    1998-07-01

    This report presents an overview of the state of conventional energy sources and the potential for development of renewable energy sources in the Central Asia countries of Kazakhstan, Uzbekistan, Kyrgyzstan, Turkmenistan, and Tajikistan. The region has a population of about 50 million in an area of more than four million square kilometers. The per capita gross internal product is more than $2,500, although the economy has been declining the past five years. The area has substantial coal, oil, uranium, and natural gas reserves, although they are not distributed equally among the five countries. Energy production is such that the countries do not have to rely heavily on imports. One of the problems in Central Asia is that the energy prices are substantially below the world prices. This is a factor in development of renewable energy sources. The primary renewable energy resources available are wind in Kazakhstan, solar in the entire region, biomass in Kyrgyzstan, and micro-hydropower stations in Kazakhstan and Kyrgyzstan. All of these have the potential to provide a significant amount of the required energy for the region. However, all of the countries have an abundance of various renewable energy resources. To effectively use these resources, however, a number of barriers to their development and commercialization must be overcome. These include low prices of conventional energy sources, absence of legislative support, lack of financing for new technologies, and lack of awareness of renewable energy sources by the population. A number of specific actions are proposed to overcome these barriers. These include establishment of a Central Asia coordinating council for renewable energy, development of a regional renewable energy program, and setting up a number of large demonstration projects. 16 figs.

    The increasing concerns over the depletion of fossil resources and its associated geo-political issues have driven the entire world to move toward sustainable forms of energy. Pretreatment is the first step in any biochemical conversion process for the production of valuable fuels/chemicals from lignocellulosic biomass to eliminate the lignin and produce fermentable sugars by hydrolysis. Conventional techniques have several limitations which can be addressed by using them in tandem with non-conventional methods for biomass pretreatment. Electron beam and γ (gamma)-irradiation, microwave and ultrasound energies have certain advantages over conventional source of energy and there is an opportunity that these energies can be exploited for biomass pretreatment.

    One of the major national economic problems of Russia is raising of agricultural production, which will provide strategic security and sustainable supply of the population with provisions. Creation of subsidiary small holdings, farm holdings, and peasant farm holdings will require addressing issues of energy supply. At considerable distance of small farms from centralized energy systems (by fuel, electricity and thermal energy) it is proposed to create a system of local energy networks on the basis of low-powered power plants using renewable energy sources (RES). There is economic unreasonableness of use of imported components of small power plants. Creation of new combined small power plants on renewable energy sources produced by domestic manufacturers is recommended. Schemes of arrangements of small power plants based on renewable energy sources are proposed, variants and characteristics of a basic source are provided—biogas plants developed by the authors. Calculations revealed that heat and power supply of self-contained farms distant from small power plants based on renewable energy sources is 2.5-2.6 times cheaper than from centralized networks. Production of biogas through anaerobic fermentation of organic waste of cattle complexes is considered as the basis. The analysis of biowaste output in various cattle farms is carried out, and the volume of biogas is determined to meet the requirements of these farms in electrical and thermal energy. The objective of the present article is to study the possibility of creating small combined power plants in Russia based on renewable sources of energy for independent consumers.

    1996-01-01

    Rapid growth in economic development coupled with the absence of an electric grid in large areas of rural China have created a need for new energy sources both in urban centers and the rural countryside. Electric capacity expansion plans call for increased use of coal-fired steam turbines for electricity production that will contribute to increased concerns over environmental pollution. China is rich in renewable energy resources, strategically located in areas of greatest need and economic viability. China is also already one of the world's largest users of renewables, especially hydro, wind, biomass, and solar thermal, and has significant experience with photovoltaics, geothermal and other technologies. The use of renewable energy is being encouraged in expanded programs at the central and provincial government levels, with growing private sector involvement. These conditions create opportunities for U.S. business participation in renewable energy markets in China.

    The feasibility of using data derived replicas from ships of opportunity for implementing matched field processing is demonstrated. The Automatic Identification System (AIS) is used to provide the library coordinates for the replica library and a correlation based processing procedure is used to overcome the impediment that the replica library is constructed from sources with different spectra and will further be used to locate another source with its own unique spectral structure. The method is illustrated with simulation and then verified using acoustic data from a 2009 experiment for which AIS information was retrieved from the United States Coast Guard Navigation Center Nationwide AIS database.

    2016-04-01

    This paper investigates the opportunities of deploying distributed sensors within the manufacturing environment of a large scale automobile plant using energy harvesting techniques. Measurements were taken in three domains at the plant in order to characterize ambient energy. Due to the location of the plant, the RF power density for radio access technologies present varied between -127 dBm/cm2 and -113 dBm/cm2. The maximum temperature difference measured within accessible distance from machine parts on the production lines surveyed was 10°C. Indoor lighting was dominant at the plant via fluorescent tubes, with average irradiance of 1 W/m2. The results obtained from this measurement campaign showed that indoor lighting was the most suitable ambient source for energy harvesting.

    This document is a study of research opportunities that are important to developing advanced technologies for efficient energy use. The study's purpose is to describe a wide array of attractive technical areas from which specific research and development programs could be implemented. Research areas are presented for potential application in each of the major end-use sectors. The study develops and applies a systematic approach to identifying and screening applied energy conservation research opportunities. To broadly cover the energy end-use sectors, this study develops useful information relating to the areas where federally-funded applied research will most likely play an important role in promoting energy conservation. This study is not designed to produce a detailed agenda of specific recommended research activities. The general information presented allows uniform comparisons of disparate research areas and as such provides the basis for formulating a cost-effective, comprehensive federal-applied energy conservation research strategy. Chapter 2 discusses the various methodologies that have been used in the past to identify research opportunities and details the approach used here. In Chapters 3, 4, and 5 the methodology is applied to the buildings, transportation, and industrial end-use sectors and the opportunities for applied research in these sectors are discussed.Chapter 6 synthesizes the results of the previous three chapters to give a comprehensive picture of applied energy conservation research opportunities across all end-use sectors and presents the conclusions to the report.

    2012-03-01

    Natural daylight is characterized by high proportions of blue light. By proof of a third type of photoreceptor in the human eye which is only sensitive in this spectral region and by subsequent studies it has become obvious that these blue proportions are essential for human health and well being. In various studies beneficial effects of indoor lighting with higher blue spectral proportions have been proven. On the other hand with increasing use of light sources having enhanced blue light for indoor illumination questions are arising about potential health risks attributed to blue light. Especially LED are showing distinct emission characteristics in the blue. Recently the French agency for food, environmental and occupational health & safety ANSES have raised the question on health issues related to LED light sources and have claimed to avoid use of LED for lighting in schools. In this paper parameters which are relevant for potential health risks will be shown and their contribution to risk factors will quantitatively be discussed. It will be shown how to differentiate between photometric parameters for assessment of beneficial as well as hazardous effects. Guidelines will be discussed how blue enhanced light sources can be used in applications to optimally support human health and well being and simultaneously avoid any risks attributed to blue light by a proper design of lighting parameters. In the conclusion it will be shown that no inherent health risks are related to LED lighting with a proper lighting design.

    The power sector is the largest user of freshwater in the U.S. The dominant use of water in power plants is for steam cycle cooling. The current portfolio of electricity generating technologies in the U.S. has highly regionalized and technology-specific requirements for water. Certain areas employ once-through cooling technologies with high withdrawals and low consumptive uses, whereas other areas employ recirculating cooling technologies with relatively low withdrawals but high consumptive uses. As water availability differs widely throughout the nation, assessments of water withdrawal and consumption impacts from the power sector must have a high geographic resolution and consider regional differences. The U.S. electricity portfolio is likely to evolve in coming years, shaped by various energy policies and economic drivers on both the national and regional level, which will impact power sector water demands. It is likely that the U.S. will continue to decarbonize its electricity industry, leading to more low-carbon technologies. However, many low-carbon technologies, such as coal with carbon capture and storage, nuclear, and concentrated solar power, can use more water than the current electricity portfolio average. National- and state-level water policies have been proposed (and enacted) that affect cooling system choices for power plants, with resulting implications for water use as well as power plant installed and operating costs and reliability. Energy policy analyses that do not consider power plant cooling system impacts may miss an important component power plant siting decisions. Similarly, water policies that do not take into consideration potential impacts on power plant operations or comprehensive regional water budget impacts may have deleterious effects on the energy industry. Analysis of future energy scenarios that incorporate technology options and constraints as well as different policies can provide useful insights about likely changes to both

    Barringer, Frank Leonard, III

    Industrial energy assessments are performed primarily to increase energy system efficiency and reduce energy costs in industrial facilities. The most common energy systems are lighting, compressed air, steam, process heating, HVAC, pumping, and fan systems, and these systems are described in this document. ASME has produced energy assessment standards for four energy systems, and these systems include compressed air, steam, process heating, and pumping systems. ASHRAE has produced an energy assessment standard for HVAC systems. Software tools for energy systems were developed for the DOE, and there are software tools for almost all of the most common energy systems. The software tools are AIRMaster+ and LogTool for compressed air systems, SSAT and 3E Plus for steam systems, PHAST and 3E Plus for process heating systems, eQUEST for HVAC systems, PSAT for pumping systems, and FSAT for fan systems. The recommended assessment procedures described in this thesis are used to set up an energy assessment for an industrial facility, collect energy system data, and analyze the energy system data. The assessment recommendations (ARs) are opportunities to increase efficiency and reduce energy consumption for energy systems. A set of recommended assessment procedures and recommended assessment opportunities are presented for each of the most common energy systems. There are many assessment opportunities for industrial facilities, and this thesis describes forty-three ARs for the seven different energy systems. There are seven ARs for lighting systems, ten ARs for compressed air systems, eight ARs for boiler and steam systems, four ARs for process heating systems, six ARs for HVAC systems, and four ARs for both pumping and fan systems. Based on a history of past assessments, average potential energy savings and typical implementation costs are shared in this thesis for most ARs. Implementing these ARs will increase efficiency and reduce energy consumption for energy systems in

    Solar energy reduces greenhouse gas emissions by an order of magnitude when substituted for fossil fuels. Nonetheless, the strategic deployment of solar energy—from single, rooftop modules to utility-scale solar energy power plants—can confer additional environmental co-benefits beyond its immediate use as a low carbon energy source. In this study, we identify a diverse portfolio of environmental co-benefit opportunities of solar energy technologies resulting from synergistic innovations in land, food, energy, and water systems. For each opportunity, we provide a demonstrative, quantitative framework for environmental co-benefit valuation—including, equations, models, or case studies for estimating carbon dioxide equivalent (CO2-eq) and cost savings ($US) averted by environmental co-benefit opportunities of solar energy—and imminent research questions to improve certainty of valuations. As land-energy-food-water nexus issues are increasingly exigent in 21st century, we show that environmental co-benefit opportunities of solar energy are feasible in numerous environments and at a wide range of spatial scales thereby able to contribute to local and regional environmental goals and for the mitigation of climate change.

    2002-06-28

    Breweries in the United States spend annually over $200 Million on energy. Energy consumption is equal to 3-8% of the production costs of beer, making energy efficiency improvement an important way to reduce costs, especially in times of high energy price volatility. After a summary of the beer making process and energy use, we examine energy efficiency opportunities available for breweries. We provide specific primary energy savings for each energy efficiency measure based on case studies that have implemented the measures, as well as references to technical literature. If available, we have also listed typical payback periods. Our findings suggest that there may still be opportunities to reduce energy consumption cost-effectively for breweries. Major brewing companies have and will continue to spend capital on cost effective measures that do not impact the quality of the beer. Further research on the economics of the measures, as well as their applicability to different brewing practices, is needed to assess implementation of selected technologies at individual breweries.

    The petroleum refining industry in the United States is the largest in the world, providing inputs to virtually any economic sector,including the transport sector and the chemical industry. The industry operates 146 refineries (as of January 2004) around the country,employing over 65,000 employees. The refining industry produces a mix of products with a total value exceeding $151 billion. Refineries spend typically 50 percent of cash operating costs (i.e., excluding capital costs and depreciation) on energy, making energy a major cost factor and also an important opportunity for cost reduction. Energy use is also a major source of emissions in the refinery industry making energy efficiency improvement an attractive opportunity to reduce emissions and operating costs. Voluntary government programs aim to assist industry to improve competitiveness through increased energy efficiency and reduced environmental impact. ENERGY STAR (R), a voluntary program managed by the U.S. Environmental Protection Agency, stresses the need for strong and strategic corporate energy management programs. ENERGY STAR provides energy management tools and strategies for successful corporate energy management programs. This Energy Guide describes research conducted to support ENERGY STAR and its work with the petroleum refining industry.This research provides information on potential energy efficiency opportunities for petroleum refineries. This Energy Guide introduces energy efficiency opportunities available for petroleum refineries.

Much progress has been made, but research opportunities are still present for all approaches. Both evolutionary and revolutionary technology development, involving foundational research, applied research, learning by doing, demonstration projects, and deployment at scale will be needed to continue this technology-innovation ecosystem. Most of the approaches still offer the potential to provide much higher efficiencies, much lower costs, improved scalability, and new functionality, relative to the embodiments of solar energy-conversion systems that have been developed to date.

    This technical report provides an overview of existing and potential financing structures for renewable energy project development in Alaska with a focus on four primary sources of project funding: government financed or supported (the most commonly used structure in Alaska today), developer equity capital, commercial debt, and third-party tax-equity investment. While privately funded options currently have limited application in Alaska, their implementation is theoretically possible based on successful execution in similar circumstances elsewhere. This report concludes that while tax status is a key consideration in determining appropriate financing structure, there are opportunities for both taxable and tax-exempt entities to participate in renewable energy project development.

    plants were chosen for a more detailed energy audit and financial assessment. Results of a detailed engineering analysis and a financial assessment of each plant led to prioritized list of recommended energy efficiency measures. The recommendations made to the plant management at two of these facilities are reported here. In addition, audits were conducted at some of the secondary plants and their results are reported as well. Some specific technologies recommended in the course of this work have included installing a new Western glass furnace at the Gostomel glass plant, which not only saves energy but also increases the volume and quality of glass production. The gas turbine cogeneration plant proposed for the coke-chemical plant will use coke-oven gas, a by-product of the coking process, as the primary fuel. Some of the more generic energy saving measures that could apply to a majority of the industrial facilities include replacing an existing compressed-air system with high-efficiency equipment, upgrading the lighting system, and installation of heat recovery systems. This paper describes the process of identifying opportunities and discusses some of the recommendations made to the plant management at some of these facilities. The paper also provides an update on the implementation plans for some of the recommended energy efficiency measures.

    The Department of Defense (DoD) has a goal of obtaining 25% of its domestic electricity from renewable sources by 2025, and also must meet federal renewable energy mandates and schedules. This report describes the analyses undertaken to study the renewable resource potential at 15 Army sites, focusing on grid-connected generation of electricity. The resources analyzed at each site include solar, wind, geothermal, biomass, waste-to-energy, and ground source heat pumps (GSHPs). For each renewable generation resource, an assessment was completed to determine the level of resource availability, and the price at which that resource would be available for electricity generation. Various design alternatives and available technologies were considered in order to determine the best way to utilize each resource and maximize cost-effective electricity generation. Economic analysis used multiple funding options, including investment by an independent power producer (IPP), Energy Savings Performance Contract (ESPC), and Energy Conservation Investment Program (ECIP), and considered tax incentives, renewable energy credits, and other economic factors to reveal the most realistic costs possible. Where resource options proved to be economically viable, implementation approaches were recommended. The intention was to focus each installation’s efforts on realistic projects, moving them from initial assessment through the design and financing to implementation. Many Army sites enjoy very low costs of electricity, limiting the number of cost-effective renewable energy options where resources are available. Waste-to-energy was often a viable option due to the additional revenue gathered from transferred tipping fees. GSHPs were also commonly cost-effective options for replacement in inefficient buildings. Geothermal, wind, and solar resources are found to be more available in certain parts of the country over others, reducing overall potential for use. Wind is variable and often most

    A {open_quotes}landforming{close_quotes} land development opportunity unique to metals mining is described. {open_quotes}Landforming{close_quotes}, wherein the earth`s surface is reconfigured with mining waste rock and tails for the capture of renewable energy, is proposed by the United States Bureau of Mines (USBM) to be ecologically acceptable and, in selected cases, economically superior to conventional mineral extraction, reclamation, and minesite abandonment practices. Landforming is primary land construction that uses mining waste and applies the principles of land overlay architecture. Landforms can be layered, shaped, and configured through the use of binders and plastic sheeting to the engineering specifications necessary for the support of physical structures and passage or retention of fluids. Landforms that are terraced and south facing (in the Northern Hemisphere) are an ideal mount for sun-tracking mirror (heliostat) arrays. In {open_quotes}blue sky{close_quotes}. solar-rich environments, the mirrors can be targeted on a common area to form a {open_quotes}solar furnace.{close_quotes} The heat generated at the focal point of the solar array can be used to flash generate steam and run a turbine electric generator. The solar steam power generation cycle coproducers distilled water that can be sprayed onto the surfaces of the landform to create {open_quotes}greenscape.{close_quotes} Waters not consumed or evaporated in the site greening process percolate into and are stored by the landform if it is underlain with plastic. The landform serves, in effect as a shallow aquifer.

    As the U.S. energy system evolves, the amount of electricity from variable-generation sources is likely to increase, which could result in additional times when electricity demand is lower than available production. Thus, purveyors of technologies that traditionally have provided base-load electricity—such as nuclear power plants—can explore new operating procedures to deal with the associated market signals. Concurrently, innovations in nuclear reactor design coupled with sophisticated control systems now allow for more complex apportionment of heat within an integrated system such as one linked to energy-intensive chemical processes. This paper explores one opportunity – nuclear-renewable hybrid energy systems. These are defined as integrated facilities comprised of nuclear reactors, renewable energy generation, and industrial processes that can simultaneously address the need for grid flexibility, greenhouse gas emission reductions, and optimal use of investment capital. Six aspects of interaction (interconnections) between elements of nuclear-renewable hybrid energy systems are identified: Thermal, electrical, chemical, hydrogen, mechanical, and information. Additionally, system-level aspects affect selection, design, and operation of this hybrid system type. Throughout the paper, gaps and research needs are identified to promote further exploration of the topic.

    A public consensus has developed on the need for national energy policies and better planning in the utilization of energy resources in Nigeria. A look at Nigeria's energy future is timely as a period of rapid technological growth and industrial development begins. At the present time, Nigeria exports a relatively high percentage (92%) of the petroleum produced annually. In addition, about 95% of all produced natural gas is flared. Only a relatively minor fraction of the coal produced is used and the rest exported to West African countries. Water power in Nigeria is not yet fully developed. Although the deposits of uranium and oil sand may be substantial, the reserves are not currently known. The proportions in which mineral fuels are used are not related to their relative abundance. Based on present production rates, domestic reserves of petroleum will last 20 years, those of natural gas 63 years, and those of coal 1503 years. Nigeria is not currently and is not likely to become self-sufficient in terms of energy requirements. During the past decade, Nigeria's population has increased by 28.4%. Of vital concern for the immediate future in Nigeria are the demands on energy consumption and mineral resources resulting from increasing population pressure.

    The purpose of this study is to identify and quantify potential energy savings available through the development and application of biotechnologies. This information is required in support of ECUT research planning efforts as an aid in identifying promising areas needing further consideration and development. It is also intended as background information for a companion ECUT study being conducted by the National Academy of Science to evaluate the use of bioprocessing methods to conserve energy. Several studies have been conducted recently to assess the status and implications of the development of biotechnology. The Office of Technology Assessment (OTA) considered institutional, economic, and scientific problems and barriers. The National Science Foundation sponsored a study to examine regulatory needs for this new and expanding technology. Somewhat in contrast to these studies, this report covers principally the technical issues. It should be emphasized that the practicality of many developments in biotechnology is not evaluated solely on the basis of energy considerations. Bioprocesses must often compete with well-established coal, petroleum, and natural gas technologies. A complete evaluation of the technical, economical, and ecological impacts of the large-scale applications discussed in this report is not possible within the scope of this study. Instead, this report assesses the potential of biotechnology to save energy so that research into all aspects of implementation will be stimulated for those industries with significant energy savings potential. 92 references, 6 figures, 24 tables.

    Energy-based instrumentation has not only facilitated the rapid adoption of laparoscopic surgery, but could be considered essential for the completion of abdominal and pelvic procedures under endoscopic guidance. For decades, relatively simple and generic reusable monopolar and bipolar systems were the only options available. More recently, the available options for energy-based surgical instrumentation have become more crowded with the introduction of ultrasound-based cutting and sealing instruments and proprietary, impedance monitoring radiofrequency coagulation devices. Such instrumentation is presented as being easier to use as well as providing greater safety and efficacy. However, these new instruments typically require the expenditure of capital for proprietary energy generators and are usually designed to be for single use, a circumstance that increases per case costs, a circumstance that begs the question of value. Do the additional costs expended for the more expensive devices translate into reduced complications, faster operating time, or even wider access to minimally invasive procedures because they enable more surgeons to offer the service? Herein is explored the complex economic issues associated with the use of energy-based surgical devices as they apply to minimal access surgery in general and to laparoscopic procedures specifically.

    In order to reach higher standards of living, man has always been interested in searching new energy sources. Natural energy from sun, wind and water has been overcame by more sophisticated resources such as coal, vapour, hydroelectricity, natural gas, petroleum, and, at least, nuclear energy. However all these resources present unwanted effects, namely various hazards to man and environment. On this matter society is quering the risk-benefit balance of some energy choices and optimum performance with new safety means to limit dangerousness are being pursued and developed. It is necessary to evaluate carefully every aspect of safety without under-estimating or over-evaluating problems. For each energy source a "real price" has to be paired, even more in the future, since more energy will be required to guarantee the necessary technological progress linked to a better quality of life. In the present review all risks related to different energy sources are described and discussed aiming at defining: 1) specific risks for different sources 2) benefit from their utilization 3) means of defence guaranteeing security for man and environment. Italy is strictly dependent for energy production, which comes for 80% from abroad. An appropriate balance is required considering economical and social factors and real availability of energy. This balance needs therefore to be clearly evaluated hoping in a better future for an alternative energy, less dangerous and more clear, such as that from nuclear fusion. PMID:2483087

A fluidized bed system is used for combustion. An example of the use of this system is briefly cited; it has extended landfill life up to 100 years for one county and allowed three counties to close municipal landfills. Over 50,000 tons of material are recycled each year, saving more than $100 million on waste disposal. Energy generation saves a chemical company over 3 million gallons of oil annually and allows the local utility company to save 75,000 tons of coal.

    Controversy exists concerning the appropriate use of carbohydrate solutions and fat emulsions as energy sources in intravenous nutritional regimens. Current evidence suggests that glucose is the carbohydrate energy source of choice and that when infused with appropriate quantities of protein it provides cheap and effective nutritional support in the majority of patients and clinical circumstances. During glucose infusion, blood glucose and acid-base balance should be closely monitored and, when indicated, exogenous insulin should be added to the regimen to combat hyperglycaemia and improve protein anabolism. Fat emulsions, although expensive, may justifiably be used in patients with moderate or severe stress to provide up to 50% of non-protein energy, especially in circumstances where attempts to satisfy energy requirements exclusively with glucose would impose an additional metabolic stress.

    2010-09-29

    The textile industry is one of the most complicated manufacturing industries because it is a fragmented and heterogeneous sector dominated by small and medium enterprises (SMEs). Energy is one of the main cost factors in the textile industry. Especially in times of high energy price volatility, improving energy efficiency should be a primary concern for textile plants. There are various energy-efficiency opportunities that exist in every textile plant, many of which are cost-effective. However, even cost-effective options often are not implemented in textile plants mostly because of limited information on how to implement energy-efficiency measures, especially given the fact that a majority of textile plants are categorized as SMEs and hence they have limited resources to acquire this information. Know-how on energy-efficiency technologies and practices should, therefore, be prepared and disseminated to textile plants. This guidebook provides information on energy-efficiency technologies and measures applicable to the textile industry. The guidebook includes case studies from textile plants around the world and includes energy savings and cost information when available. First, the guidebook gives a brief overview of the textile industry around the world, with an explanation of major textile processes. An analysis of the type and the share of energy used in different textile processes is also included in the guidebook. Subsequently, energy-efficiency improvement opportunities available within some of the major textile sub-sectors are given with a brief explanation of each measure. The conclusion includes a short section dedicated to highlighting a few emerging technologies in the textile industry as well as the potential for the use of renewable energy in the textile industry.

  16. Energy efficiency standards for residential and commercial equipment: Additional opportunities

    SciTech Connect

    Rosenquist, Greg; McNeil, Michael; Iyer, Maithili; Meyers, Steve; McMahon, Jim

    2004-08-02

    Energy efficiency standards set minimum levels of energy efficiency that must be met by new products. Depending on the dynamics of the market and the level of the standard, the effect on the market for a given product may be small, moderate, or large. Energy efficiency standards address a number of market failures that exist in the buildings sector. Decisions about efficiency levels often are made by people who will not be responsible for the energy bill, such as landlords or developers of commercial buildings. Many buildings are occupied for their entire lives by very temporary owners or renters, each unwilling to make long-term investments that would mostly reward subsequent users. And sometimes what looks like apathy about efficiency merely reflects inadequate information or time invested to evaluate it. In addition to these sector-specific market failures, energy efficiency standards address the endemic failure of energy prices to incorporate externalities. In the U.S., energy efficiency standards for consumer products were first implemented in California in 1977. National standards became effective starting in 1988. By the end of 2001, national standards were in effect for over a dozen residential appliances, as well as for a number of commercial sector products. Updated standards will take effect in the next few years for several products. Outside the U.S., over 30 countries have adopted minimum energy performance standards. Technologies and markets are dynamic, and additional opportunities to improve energy efficiency exist. There are two main avenues for extending energy efficiency standards. One is upgrading standards that already exist for specific products. The other is adopting standards for products that are not covered by existing standards. In the absence of new and upgraded energy efficiency standards, it is likely that many new products will enter the stock with lower levels of energy efficiency than would otherwise be the case.

    New scientific frontiers, recent advances in theory, and rapid increases in computational capabilities have created compelling opportunities for theory and computation to advance the scientific mission of the Office of Basic Energy Sciences (BES). The prospects for success in the experimental programs of BES will be enhanced by pursuing these opportunities. This report makes the case for an expanded research program in theory and computation in BES. The Subcommittee on Theory and Computation of the Basic Energy Sciences Advisory Committee was charged with identifying current and emerging challenges and opportunities for theoretical research within the scientific mission of BES, paying particular attention to how computing will be employed to enable that research. A primary purpose of the Subcommittee was to identify those investments that are necessary to ensure that theoretical research will have maximum impact in the areas of importance to BES, and to assure that BES researchers will be able to exploit the entire spectrum of computational tools, including leadership class computing facilities. The Subcommittee s Findings and Recommendations are presented in Section VII of this report.

    Compressed air is a common energy medium. The production of compressed air itself is not a very efficient process. Avoiding any unnecessary losses of air can lead to large reductions in electricity consumption. Since blowing applications are one of the main domains were compressed-air is used, any reduction in the mass flow needed for operation can lead to significant energy savings. In this paper the normal volumetric flow rate and generated impact force are compared between a stepped nozzle and a so called energy saving nozzle which allows extra air from the surroundings to be entrained. These two different nozzle geometries are used in industrial blowing applications. Until now there was no study available which compares the impact forces and volumetric flow rates for these types of nozzles. The flow field of the two nozzles was calculated by CFD simulations. The impact forces and volumetric flow rates are calculated out of this flow field. Each nozzle was simulated with three different input pressures. The nozzles were simulated with an input pressure of 3, 4 and 5 barg. The energy saving nozzle consumes only 1 % less volumetric flow rate then the stepped nozzle at the same inlet pressure. The replacement of a stepped nozzle with an energy saving nozzle will not immediately result in a decrease in input volumetric flow rate. The pressure at the inlet of the energy saving nozzle has to be reduced as well. After reducing the input pressure the energy saving nozzle generates the same impact force than the stepped nozzle. Hereby a decrease of 4.5 % in input volumetric flow rate was possible. The energy cost will decrease with 4.5 % as well because the normal volumetric flow rate is directly proportional to the energy cost. The replacement of a stepped nozzle with an energy saving nozzle while maintaining the same inlet pressure is only useful when the impact force from the stepped nozzle is not sufficient. The energy saving nozzle can generate 5.6 % more impact

    China's remarkable economic growth has been supported by a generally adequate and relatively low-cost supply of energy, creating the world's largest coal industry, its second-largest oil market, and an eclectic power business that is adding capacity at an unprecedented rate. If energy requirements continue to double every decade, China will not be able to meet the energy demands of the present without seriously compromising the ability of future generations to meet their own energy needs. This title uses historical data from 1980 and alternative scenarios through 2020 to assess China's future energy requirements and the resources to meet them. It calls for a high-level commitment to develop and implement an integrated, coordinated, and comprehensive energy policy. The authors recommend eight building blocks to reduce energy consumption growth well below the targeted rate of economic growth, to use national resources on an economically and environmentally sound basis, and to establish a robust energy system that can better ensure the security of a diverse supply of competitively priced energy forms. Sustainability calls for persistence of effort, greater reliance on advanced energy technologies, and better standards enforcement. Achieving these goals will require policy initiatives that restrict demand and create a 'resources-conscious society', reconcile energy needs with environmental imperatives, rationalize pricing, and tackle supply security. While the challenges are daunting, China has a unique opportunity to position itself as a world leader in the application of cutting-edge energy developments to create a sustainable energy sector effectively supporting a flourishing economy and society.

    The renaissance of nuclear energy for electricity and hydrogen production and process heat for other potential applications is moving ahead rapidly. Both near- and far-term roles are envisioned for this important energy technology, and each of these roles will have its own particular technical challenges and opportunities. Numerous power producers world-wide are actively considering the construction of new nuclear power plants for the production of electricity in the near-term. The U.S. Department of Energy has announced plans to develop both the next generation of nuclear power plants and the technology necessary to recycle used nuclear fuel. These exciting technologies will bring novel challenges to their developers and designers as they push the knowledge base in materials utilization, high temperatures and pressures, extended operating cycles, and extreme operating environments. Development of the techniques and methods to interrogate, understand, manage and control these devices will be crucial to enabling the full extension of these technologies.

    Electrocatalytic energy conversion has been considered as one of the most efficient and promising pathways for realizing energy storage and energy utilization in modern society. To improve electrocatalytic reactions, specific catalysts are needed to lower the overpotential. In the search for efficient alternatives to noble metal catalysts, transition metal nitrides have attracted considerable interest due to their high catalytic activity and unique electronic structure. Over the past few decades, numerous nitride-based catalysts have been explored with respect to their ability to drive various electrocatalytic reactions, such as the hydrogen evolution reaction and the oxygen evolution reaction to achieve water splitting and the oxygen reduction reaction coupled with the methanol oxidation reaction to construct fuel cells or rechargeable Li-O2 batteries. This Minireview provides a brief overview of recent progress on electrocatalysts based on transition metal nitrides, and outlines the current challenges and future opportunities. PMID:26494184

  6. Implementation of the Energy Efficiency Directive: Opportunities and Challenges

    2015-12-01

    Discussions in Latvia are ongoing regarding the optimum solution to implementing Directive 2012/27/EU of the European Parliament and of the Council of 25 October 2012 on energy efficiency, amending Directives 2009/125/EC and 2010/30/EU and repealing Directives 2004/8/EC and 2006/32/EC (Directive 2012/27/EU). Without a doubt, increased energy efficiency contributes significantly to energy supply security, competitive performance, increased quality of life, reduced energy dependence and greenhouse gas (GHG) emissions. However, Directive 2012/27/EU should be implemented with careful planning, evaluating every aspect of the process. This study analyses a scenario, where a significant fraction of target energy efficiency is achieved by obliging energy utilities to implement user-end energy efficiency measures. With implementation of this scheme towards energy end-use savings, user payments for energy should be reduced; on the other hand, these measures will require considerable investment. The energy efficiency obligation scheme stipulates that these investments must be paid by energy utilities; however, they will actually be covered by users, because the source of energy utilities' income is user payments for energy. Thus, expenses on such measures will be included in energy prices and service tariffs. The authors analyse the ways to achieve a balance between user gains from energy end-use savings and increased energy prices and tariffs as a result of obligations imposed upon energy utilities. Similarly, the suitability of the current regulatory regime for effective implementation of Directive 2012/27/EU is analysed in the energy supply sectors, where supply tariffs are regulated.

    In this paper, we present a series of hybrid energy configurations that are designed to provide a robust power source for embedded sensing hardware. The proper management of energy resources is a critical component in the design of any deployed sensing network. For systems that are installed in remote or inaccessible locations, or those with an operational lifespan that exceeds traditional battery technologies, energy harvesting is an attractive alternative. Unfortunately, the dependence on a single energy source (i.e. solar) can cause potential problems when environmental conditions preclude the system from operating at peak performance. In this paper we consider the use of a hybrid energy source that extracts energy from multiple sources and uses this collective energy to power sensing hardware. The sources considered in this work include: solar, vibration, thermal gradients, and RF energy capture. Methods of increasing the efficiency, energy storage medium, target applications and the integrated use of energy harvesting sources with wireless energy transmission will be discussed.

    2009-07-01

    Early experiences with energy savings certificates (ESCs) have revealed their merits and the challenges associated with them. While in the United States ESC markets have yet to gain significant traction, lessons can be drawn from early experiences in the states of Connecticut and New York, as well as from established markets in Italy, France, and elsewhere. The staying power of European examples demonstrates that ESCs can help initiate more efficiency projects. This article compares ESCs with renewable energy certificates (RECs), looks at the unique opportunities and challenges they present, and reviews solutions and best practices demonstrated by early ESC markets. Three major potential ESC market types are also reviewed: compliance, voluntary, and carbon. Additionally, factors that will benefit ESC markets in the United States are examined: new state EEPS policies, public interest in tools to mitigate climate change, and the growing interest in a voluntary market for ESCs.

    2008-01-31

    This report provides information on the energy savings, costs, and carbon dioxide emissions reductions associated with implementation of a number of technologies and measures applicable to the cement industry. The technologies and measures include both state-of-the-art measures that are currently in use in cement enterprises worldwide as well as advanced measures that are either only in limited use or are near commercialization. This report focuses mainly on retrofit measures using commercially available technologies, but many of these technologies are applicable for new plants as well. Where possible, for each technology or measure, costs and energy savings per tonne of cement produced are estimated and then carbon dioxide emissions reductions are calculated based on the fuels used at the process step to which the technology or measure is applied. The analysis of cement kiln energy-efficiency opportunities is divided into technologies and measures that are applicable to the different stages of production and various kiln types used in China: raw materials (and fuel) preparation; clinker making (applicable to all kilns, rotary kilns only, vertical shaft kilns only); and finish grinding; as well as plant wide measures and product and feedstock changes that will reduce energy consumption for clinker making. Table 1 lists all measures in this report by process to which they apply, including plant wide measures and product or feedstock changes. Tables 2 through 8 provide the following information for each technology: fuel and electricity savings per tonne of cement; annual operating and capital costs per tonne of cement or estimated payback period; and, carbon dioxide emissions reductions for each measure applied to the production of cement. This information was originally collected for a report on the U.S. cement industry (Worrell and Galitsky, 2004) and a report on opportunities for China's cement kilns (Price and Galitsky, in press).

  12. Future Physics Opportunities in Beam Energy Scan at RHIC

    NASA Astrophysics Data System (ADS)

    Xu, Nu

    2015-10-01

    In the first phase of the beam energy scan program (BES-I) at RHIC, we have collected data from Au +Au collisions at the center of mass energy range from 7.7 GeV to 39 GeV, corresponding to the baryonic chemical potential of 420 MeV to 120 MeV, respectively. We have observed the disappearance of the suppression of leading hadrons at large pT, break down of the quark scaling in the identified particle elliptic flow, the net-proton directed flow slope dv1/dy shows a minimum with negative sign, and a non-monotonical behavior of the net-proton correlation function (the fourth order) at the energy less than 20 GeV. All of these observations indicate that the property of the medium at high baryon density is dramatically different from that created at the RHIC top energy where the baryon density is small and partonic interactions are dominant. In this talk I will first review what we have learned in RHIC BES-I. Then I will discuss the opportunities in the future bean energy scan program in order to address key questions regarding the QCD phase structure including the illusive critical point. I will stress that adequate detector upgrades, focused at the large baryon density region, are essential for the physics program.

  13. The RHIC Beam Energy Scan: Present Challenges and Coming Opportunities

    2015-10-01

    The RHIC Beam Energy Scan is mapping the phase diagram of QCD, creating and probing quark-gluon plasma ``doped'' to varying degrees with an excess of quarks over antiquarks. Recent data from the first phase of the scan challenge us to understand intriguing non-monotonic collision energy dependence (and therefore doping dependence) of various observables. They hint at a reduction in the QGP pressure, long anticipated in collisions that form QGP at temperatures not far above the crossover region. As the collision energy is lowered, possible signs of the turning off of effects driven by the chiral anomaly, signaling the approximate restoration of chiral symmetry, have been seen. And, there are tantalizing indications of a substantial drop and a subsequent substantial rise in a fluctuation observable that is particularly sensitive to critical fluctuations and that has been predicted to do exactly that the doping increases if a critical point on the phase diagram is approached. Each of these points to opportunities for discovery in the second phase of the scan (BES-II), coming in 2019-20, with much higher statistics data at the low energies where the most tantalizing effects reside. Today, though, the ball is squarely in the theorists' court: the data demand a concerted, multifaceted, theoretical response, building a quantitative framework for modeling the salient features of lower energy heavy ion collisions. If we respond well to this present challenge, BES-II can turn today's trends and features into discoveries, conclusions, and new understanding.

    This article presents a summary of research issues and opportunities in alternative energy source research identified by panels of experts assembled by the Engineering Directorate of the US National Science Foundation. The objective was to identify transformative research issues and opportunities to make alternative energy sources viable. The article presents motivations for energy research, grand challenges, and specific challenges in the research areas covered. The grand challenges identified for the United States include supplying 30% of US electricity from photovoltaics by 2030, supplying 25% of US electricity from wind by 2025, displacing 30% of US hydrocarbon use by 2030 with bio-based products, and providing a practical 250-300 W h/kg energy storage system by 2025. Similar challenges could be outlined along the same lines for the remainder of the world. Examples of specific areas of research focus identified as promising include high performance p-type transparent conductors, multijunction thin-film photovoltaic devices, defects in chalcogenide semiconductors, experimental study and numerical modeling of the fluid mechanics of airflow as applied to wind turbines, improved materials for wind turbines, methods for creating high energy density transportable biological feedstocks, biorefinery processes yielding infrastructure-compatible biofuels and biochemicals directly, and improved electrodes and electrolytes for Li ion batteries. Arguments for each of these as research priorities are given.

    Solar energy installations in arid and semi-arid regions are rapidly increasing, due to technological advances and policy changes. Large-scale expansion of solar infrastructure can adversely impact land and water resources. A major challenge is how to meet the ever-expanding energy demand with limited land and water resources, in the context of increasing competition from agricultural and domestic consumption. We explored opportunities to co-locate solar infrastructures and agricultural crops or biofuel feedstocks to maximize the efficiency of land and water use. We considered energy inputs/outputs, water use, greenhouse gas emissions and economics of solar installations in comparison to location-specific agricultural /biofuel crops in different arid regions of the world. The life cycle analyses show that co-located systems are economically viable in some areas and may provide opportunities for electrification and stimulate economic growth in rural areas. The water inputs for cleaning solar panels (photo voltaic) or mirrors (concentrated solar) and dust suppression are similar to amounts required for the desert-adapted crops (e.g. agave, aloe) considered in the study, suggesting the possibility of integrating the two systems to maximize water and land use efficiency. A life-cycle analysis of a hypothetical co-location indicated higher returns per m3 of water used than either system alone. Arid and semi arid regions of the world are experiencing high population growth, creating additional demand for land and water resources. In these water limited areas, coupled solar infrastructure and agriculture could be established on marginal lands, thus minimizing the socioeconomic and environmental issues resulting from cultivation of high value non-food crops in prime agricultural lands.

    A spate of recently enacted energy legislation and associated program changes is providing numerous opportunities to help California federal energy managers cut costs and meet their renewables, energy efficiency and GHG emissions goals. In April 2011, Governor Jerry Brown approved the nation’s most ambitious renewable portfolio standard (RPS), which requires 33% of the state’s electricity to come from renewable energy sources by 2020. Policy changes that will support the RPS include expanded eligibility rules that fill previous gaps in incentives for certain sizes of on-site renewable energy systems. Program updates described in this document include: $200 million more in funding for California Solar Initiative rebates to commercial and industrial customers; an increase in the eligible system size for the Feed-In-Tariff (FIT) from 1.5MW to 3MW; and pending changes that may allow customer-side systems to sell tradable renewable energy credits (TRECs) to entities with RPS compliance obligations in California.

    Despite common characterizations of modern wind energy technology as mature, there remains a persistent disconnect between the vast global wind energy resource—which is 20 times greater than total global power consumption—and the limited penetration of existing wind energy technologies as a means for electricity generation worldwide. We describe an approach to wind energy harvesting that has the potential to resolve this disconnect by geographically distributing wind power generators in a manner that more closely mirrors the physical resource itself. To this end, technology development is focused on large arrays of small wind turbines that can harvest wind energy at low altitudes by using new concepts of biology-inspired engineering. This approach dramatically extends the reach of wind energy, as smaller wind turbines can be installed in many places that larger systems cannot, especially in built environments. Moreover, they have lower visual, acoustic, and radar signatures, and they may pose significantly less risk to birds and bats. These features can be leveraged to attain cultural acceptance and rapid adoption of this new technology, thereby enabling significantly faster achievement of state and national renewable energy targets than with existing technology alone. Favorable economics stem from an orders-of-magnitude reduction in the number of components in a new generation of simple, mass-manufacturable (even 3D-printable), vertical-axis wind turbines. However, this vision can only be achieved by overcoming significant scientific challenges that have limited progress over the past three decades. The following essay summarizes our approach as well as the opportunities and challenges associated with it, with the aim of motivating a concerted effort in basic and applied research in this area.

    Sometimes the greatest investment opportunities are in those areas where the least progress seems to be taking place. This report describes energy-based developments taking place in the Persian/Arabian Gulf. The 8 Gulf states are building their nations; each has large minority groups and swelling populations; their economies are built on one product (hydrocarbons). Large expatriate populations, being integrated into local societies and economies, have led to hostility and guarded access to contacts with the outside world. Gulf nations cannot benefit from any oil price rise as they did in the past, as their populations have grown too rapidly. Policies change daily and can be changed back to original ones as well as into new ones. Since the oil and gas industries are the primary source of government revenue, oil and gas are likely to remain longest under government control. A breakdown of energy-base investment potentials in the Middle East is tabulated: upstream oil, refining, domestic oil marketing, upstream gas, LNG, electricity, petrochemical.

    Limitations on current wastewater treatment plant (WWTP) biological processes and solids disposal options present opportunities to implement novel technologies that convert WWTPs into resource recovery facilities. This review considered replacing or augmenting extensive dewatering, anaerobic digestion, and off-site disposal with new thermo-chemical and liquid extraction processes. These technologies may better recover energy and metals while inactivating pathogens and destroying organic pollutants. Because limited direct comparisons between different sludge types exist in the literature for hydrothermal liquefaction, this study augments the findings with experimental data. These experiments demonstrated 50% reduction in sludge mass, with 30% of liquefaction products converted to bio-oil and most metals sequestered within a small mass of solid bio-char residue. Finally, each technology's contribution to the three sustainability pillars is investigated. Although limiting hazardous materials reintroduction to the environment may increase economic cost of sludge treatment, it is balanced by cleaner environment and valuable resource benefits for society.

    The high brightness, high intensity, and pulsed time-structure of synchrotron sources provide new opportunities for time-resolved x-ray diffraction investigations. With third generation synchrotron sources coming on line, high brilliance and high brightness are now available in x-ray beams with the highest flux. In addition to the high average flux, the instantaneous flux available in synchrotron beams is greatly enhanced by the pulsed time structure, which consists of short bursts of x-rays that are separated by {approximately}tens to hundreds of nanoseconds. Time-resolved one- and two-dimensional position sensitive detection techniques that take advantage of synchrotron radiation for materials science x-ray diffraction investigations are presented, and time resolved materials science applications are discussed in terms of recent diffraction and spectroscopy results and materials research opportunities.

It is intended for strategists and researchers seeking to identify market potential for their products and services in all sectors of the China energy industry. The report is in 4 Sections: Overview of China Energy Market; Market Analysis; Market Segments (including electricity and coal); and Breaking into theMmarket. China's economic trajectory has driven its expanding energy needs, and it is now the world's second largest energy consumer behind the United States. China's energy sector has enormous potential, especially the coal, petroleum and natural gas industries, yet China is currently a net importer of oil, and imports are expected to increase to more than 900 million barrels in 2006, against a total demand of 1.993 billion barrels per year. China is looking to expand its production of coal, natural gas, and renewable energy sources such as nuclear, solar and hydroelectric power to meet the enormous appetite for energy spawned by its massive industrial complex and consumer sectors. It is estimated that in 2020, China will need 2.8 billion tons of coal and 600 million tons of crude oil, two and a half times more than in 2000.

    Young people these days are very concerned about the environment. There is also a great deal of interest in using technology to improve energy efficiency. Many physics students share these concerns and would like to find ways to use their scientific and quantitative skills to help overcome the environmental challenges that the world faces. This may be particularly true for female students. Showing physics students how they can contribute to environmental and energy solutions while doing scientific research which excites them is expected to attract more physicists to work on these very important problems and to retain more of the best and the brightest in physical science. This is a major thrust of the 'Gathering Storm' report, the 'American Competitiveness Initiative' report, and several other studies. With these concerns in mind, the American Physical Society (APS) and more specifically, the newly formed APS Topical Group on Energy Research and Applications (GERA), organized and conducted a one-day workshop for graduate students and post docs highlighting the contributions that physics-related research can make to meeting the nation's energy needs in environmentally friendly ways. A workshop program committee was formed and met four times by conference call to determine session topics and to suggest appropriate presenters for each topic. Speakers were chosen not only for their prominence in their respective fields of energy research but also for their ability to relate their work to young people. The workshop was held the day before the APS March Meeting on March 14, 2009 in Portland, OR. The workshop was restricted to approximately 80 young physicists to encourage group discussion. Talks were planned and presented at a level of participants with a physics background but no special knowledge of energy research. Speakers were asked to give a broad overview of their area of research before talking more specifically about their own work. The format was designed with

    The Missouri Agricultural Energy Saving Team-A Revolutionary Opportunity (MAESTRO) program brought together a team of representatives from government, academia, and private industry to enhance the availability of energy efficiency services for small livestock producers in the State of Missouri. The Missouri Department of Agriculture (MDA) managed the project via a subcontract with the University of Missouri (MU), College of Agriculture Food and Natural Resources, MU Extension, the MU College of Human Environmental Sciences, the MU College of Engineering, and the Missouri Agricultural and Small Business Development Authority (MASBDA). MU teamed with EnSave, Inc, a nationally-recognized expert in agricultural energy efficiency to assist with marketing, outreach, provision of farm energy audits and customer service. MU also teamed with independent home contractors to facilitate energy audits of the farm buildings and homes of these livestock producers. The goals of the project were to: (1) improve the environment by reducing fossil fuel emissions and reducing the total energy used on small animal farms; (2) stimulate the economy of local and regional communities by creating or retaining jobs; and (3) improve the profitability of Missouri livestock producers by reducing their energy expenditures. Historically, Missouri scientists/engineers conducted programs on energy use in agriculture, such as in equipment, grain handling and tillage practices. The MAESTRO program was the first to focus strictly on energy efficiency associated with livestock production systems in Missouri and to investigate the applicability and potential of addressing energy efficiency in animal production from a building efficiency perspective. A. Project Objectives The goal of the MAESTRO program was to strengthen the financial viability and environmental soundness of Missouri's small animal farms by helping them implement energy efficient technologies for the production facility, farm buildings

    As communities grow, greater demands are placed on water supplies, wastewater services, and the electricity needed to power the growing water services infrastructure. Water is also a critical resource for thermoelectric power plants. Future population growth in the United States is therefore expected to heighten competition for water resources. Many parts of the United States with increasing water stresses also have significant wind energy resources. Wind power is the fastest-growing electric generation source in the United States and is decreasing in cost to be competitive with thermoelectric generation. Wind energy can offer communities in water-stressed areas the option of economically meeting increasing energy needs without increasing demands on valuable water resources. Wind energy can also provide targeted energy production to serve critical local water-system needs. The research presented in this report describes a systematic assessment of the potential for wind power to support water utility operation, with the objective to identify promising technical applications and water utility case study opportunities. The first section describes the current situation that municipal providers face with respect to energy and water. The second section describes the progress that wind technologies have made in recent years to become a cost-effective electricity source. The third section describes the analysis employed to assess potential for wind power in support of water service providers, as well as two case studies. The report concludes with results and recommendations.

    1995-11-01

    Electricity produced from burning sugarcane bagasse has provided as much as 10 percent of Hawaii`s electricity supply in the past. As sugarcane production has ceased on the islands of Oahu and Hawaii and diminished on Maui and Kauai, the role of biomass energy will be reduced unless economically viable alternatives can be identified. An empirical biomass yield and cost system model linked to a geographical information system has been developed at the University of Hawaii. This short-rotation forestry decision support system was used to estimate dedicated biomass feedstock supplies and delivered costs of tropical hardwoods for ethanol, methanol, and electricity production. Output from the system model was incorporated in a linear programming optimization model to identify the mix of tree plantation practices, wood processing technologies, and end-products that results in the highest economic return on investment under given market situations. An application of these decision-support tools is presented for hypothetical integrated forest product systems established at two former sugarcane plantations in Hawaii. Results indicate that the optimal profit opportunity exists for the production of medium density fibreboard and plywood, with annual net return estimates of approximately $3.5 million at the Hamakua plantation on the island of Hawaii and $2.2 million at the Waialua plantation on Oahu. Sensitivity analyses of the effects of different milling capacities, end-product market prices, increased plantation areas, and forced saw milling were performed. Potential economic credits for carbon sequestration and wastewater effluent management were estimated. While biofuels are not identified as an economical viable component, energy co-products may help reduce market risk via product diversification in such forestry ventures.

    2010-06-01

    The American Recovery and Reinvestment Act of 2009 (Recovery Act) highlighted the importance of reducing the Nation's dependence on foreign oil and conserving scarce energy resources. The Department of Energy, as the designated lead agency for promoting new technologies, providing leadership for energy conservation and helping Federal agencies reduce energy costs, plays a pivotal role in achieving the Recovery Act's energy related goals. The Department spends nearly $300 million per year in energy costs for its 9,000 buildings at 24 sites. Electricity costs, totaling $190 million, account for close to two-thirds of the Department's total energy expenditures, with roughly 40 percent or $76 million of those costs attributable to the cost of lighting. New lighting technologies and advanced lighting systems offer the Department the opportunity to significantly reduce energy consumption; decrease operating costs at its sites throughout the country; and, demonstrate the benefits of using new lighting technologies that are currently being developed in its laboratories and by other sources. Because of its energy conservation leadership role, we initiated this audit to determine whether the Department's facilities had implemented lighting conservation measures.

    The objectives of this study were to prepare a summary report that examines the opportunities for and obstacles to the integration of renewable energy resources in the Southeast between now and the year 2030. The report, which is based on a review of existing literature regarding renewable resources in the Southeast, includes the following renewable energy resources: wind, solar, hydro, geothermal, biomass, and tidal. The evaluation was conducted by the Oak Ridge National Laboratory for the Energy Foundation and is a subjective review with limited detailed analysis. However, the report offers a best estimate of the magnitude, time frame, and cost of deployment of renewable resources in the Southeast based upon the literature reviewed and reasonable engineering and economic estimates. For the purposes of this report, the Southeast is defined as the states of Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Virginia, and West Virginia. In addition, some aspects of the report (wind and geothermal) also consider the extended Southeast, which includes Maryland, Missouri, Oklahoma, and Texas. A description of the existing base of renewable electricity installations in the region is given for each technology considered. Where available, the possible barriers and other considerations regarding renewable energy resources are listed in terms of availability, investment and maintenance costs, reliability, installation requirements, policies, and energy market. As stated above, the report is a comprehensive review of renewable energy resources in the southeastern region of United States based on a literature study that included information obtained from the Southern Bio-Power wiki, sources from the Energy Foundation, sources available to ORNL, and sources found during the review. The report consists of an executive summary, this introductory chapter describing report objectives, a chapter on analysis methods and

    In the decade since the Low Energy Neutron Source (LENS) at Indiana University Center for Exploration of Energy and Matter (CEEM) produced its first neutrons, the facility has made important contributions to the international neutron scattering community. LENS employs a 13MeV proton beam at up to 4kW beam power onto one of two Be targets to produce neutrons for research in fields ranging from radiation effects in electronics to studies of the structure of fluids confined in nanoporous materials. The neutron source design at the heart of LENS facilitates relatively rapid hands-on access to most of its components which provides a foundation for a research program in experimental neutronics and affords numerous opportunities for novel educational experiences. We describe in some detail a number of the unique capabilities of this facility.

    Isotope batteries offer solutions for long-lived low-power sensor requirements. Alpha emitting isotopes have energy per decay 103 times that of beta emitters. Alpha particles are absorbed within 20 μm of most materials reducing shielding mitigation. However, damage to materials from the alphas limits their practical use. A Schottky Barrier Diode (SBD) geometry is considered with an alpha emitting contact-layer on a diamond-like crystal semiconductor region. The radiation tolerance of diamond, the safety of alpha particles, combined with the internal field of the SBD is expected to generate current useful for low-power electronic devices over decades. Device design parameters and calculations of the expected current are described.

    2013-11-01

    Master Limited Partnerships (MLPs) and Real Estate Investment Trusts (REITs) are two proposed investment vehicles which have the potential to lower renewable energy assets' high cost of capital; a critical factor in the Department of Energy's goal for renewable energy to achieve grid-parity with traditional sources of electric generation. Due to current U.S. federal income tax laws, regulations, and administrative interpretations, REITs and MLPs cannot finance a significant portion of the cost of renewable energy assets. Efforts are underway to alter these rules by changing the definition of 'real property' (REIT) and 'qualified income' (MLP). However, even with rule changes, both investment vehicles have structural challenges to efficiently finance renewable energy assets. Among them are 1) effectively utilizing the U.S. federal income tax incentives; 2) administratively structuring the investments to not be overly onerous or complicated, given the potential for pooling a relatively large amount of small assets; and 3) attracting and retaining a large enough investment community to participate in the funding opportunities. This report summarizes these challenges so that if proposed federal changes are made, stakeholders have an understanding of the possible outcomes.

    From the beginning of its discovery the Moessbauer effect has continued to be one of the most powerful tools with broad applications in diverse areas of science and technology. With the advent of synchrotron radiation sources such as the Advanced Photon Source (APS), the European Synchrotron Radiation Facility (ESRF) and the Super Photon Ring-8 (SPring-8), the tool has enlarged its scope and delivered new capabilities. The popular techniques most generally used in the field of materials physics, chemical physics, geoscience, and biology are hyperfine spectroscopy via elastic nuclear forward scattering (NFS), vibrational spectroscopy via nuclear inelastic scattering (NRIXS), and, to a lesser extent, diffusional dynamics from quasielastic nuclear forward scattering (QNFS). As we look ahead, new storage rings with enhanced brilliance such as PETRA-III under construction at DESY, Hamburg, and PEP-III in its early design stage at SLAC, Stanford, will provide new and unique science opportunities. In the next two decades, x-ray free-electron lasers (XFELs), based both on self-amplified spontaneous emission (SASE-XFELs) and a seed (SXFELs), with unique time structure, coherence and a five to six orders higher average brilliance will truly revolutionize nuclear resonance applications in a major way. This overview is intended to briefly address the unique radiation characteristics of new sources on the horizon and to provide a glimpse of scientific prospects and dreams in the nuclear resonance field from the new radiation sources. We anticipate an expanded nuclear resonance research activity with applications such as spin and phonon mapping of a single nanostructure and their assemblies, interfaces, and surfaces; spin dynamics; nonequilibrium dynamics; photochemical reactions; excited-state spectroscopy; and nonlinear phenomena.

    expressed at the atomic and electronic scales, it can dominate the macroscopic properties of materials and chemical reactions such as superconductivity and efficient photosynthesis. In recent years, enormous progress has been made in recognizing, manipulating, and exploiting quantum coherence. This progress has already elucidated the role that symmetry plays in protecting coherence in key materials, taught us how to use light to manipulate atoms and molecules, and provided us with increasingly sophisticated techniques for controlling and probing the charges and spins of quantum coherent systems. With the arrival of new sources of coherent light and electron beams, thanks in large part to investments by the U.S. Department of Energy’s Office of Basic Energy Sciences (BES), there is now an opportunity to engineer coherence in heterostructures that incorporate multiple types of materials and to control complex, multistep chemical transformations. This approach will pave the way for quantum information processing and next-generation photovoltaic cells and sensors. Revolutionary Advances in Models, Mathematics, Algorithms, Data, and Computing Science today is benefiting from a convergence of theoretical, mathematical, computational, and experimental capabilities that put us on the brink of greatly accelerating our ability to predict, synthesize, and control new materials and chemical processes, and to understand the complexities of matter across a range of scales. Imagine being able to chart a path through a vast sea of possible new materials to find a select few with desired properties. Instead of the time-honored forward approach, in which materials with desired properties are found through either trial-and-error experiments or lucky accidents, we have the opportunity to inversely design and create new materials that possess the properties we desire. The traditional approach has allowed us to make only a tiny fraction of all the materials that are theoretically possible. The

    As energy efficiency in buildings continues to move from discreet technology development to an integrated systems approach, the need to understand and integrate complementary goals and targets becomes more pronounced. Whether within Department of Energy’s (DOE) Building Technologies Program (BTP), across the Office of Energy Efficiency and Renewable Energy (EERE), or throughout DOE and the Federal government, mutual gains and collaboration synergies exist that are not easily achieved because of organizational and time constraints. There also cases where federal agencies may be addressing similar issues, but with different (and sometimes conflicting) outcomes in mind. This report conducts a comprehensive inventory across all EERE and other relevant Federal agencies of potential activities with synergistic benefits. A taxonomy of activities with potential interdependencies is presented. The report identifies a number of federal program objectives, products, and plans related to building energy efficiency and characterizes the current structure and interactions related to these plans and programs. Areas where overlap occurs are identified as are the challenges of addressing issues related to overlapping goals and programs. Based on the input gathered from various sources, including 20 separate interviews with federal agency staff and contractor staff supporting buildings programs, this study identifies a number of synergistic opportunities and makes recommends a number of areas where further collaboration could be beneficial.

    We empirically estimated the total energy loss from the atmospheric regions above the photo sphere in T Tauri stars. We have also estimated the flux input into the atmosphere by magnetohydrodynamic (MHD) aves produced in the subphotospheric convection zone. Within the uncertainties of both theory and observations, this flux seems to represent the basic energy input into the atmosphere provided that a large surface coverage of magnetic regions exists. In addition to this basic energy input from the convection zone the T Tauri atmospheres must have other energy sources, originating in the stellar surfitee. Among those we can include the flux of energy carried by Alfven waves resulting from the action of surface material motions on magnetic flux tubes, as well as dissipation and annihilation of magnetic fields in flare events. The observed decrease in emission line fluxes with luminosity seems to indicate that MHD wave fluxes heat the chromosphere, while the uppermost atmospheric regions require another source of heating.

    Major changes in the law governing the electric industry are underway, fundamentally altering how the generation and sale of electric power is regulated and how electric power is marketed in the United States. Legislative and regulatory initiatives promoting competition will create a variety of opportunities, and commensurate risks, for power generators, marketers, brokers, sellers, and purchasers. To succeed in the new marketplace, suppliers of renewable energy must understand the changes occurring on the state and federal levels, and position themselves to take advantage of the opportunities available. In this environment, monitoring and participating in state and federal legislative and regulatory efforts will be crucial for maximizing opportunities for wind energy.

    Annually, breweries in the United States spend over $200 million on energy. Energy consumption is equal to 38 percent of the production costs of beer, making energy efficiency improvement an important way to reduce costs, especially in times of high energy price volatility. After a summary of the beer making process and energy use, we examine energy efficiency opportunities available for breweries. We provide specific primary energy savings for each energy efficiency measure based on case studies that have implemented the measures, as well as references to technical literature. If available, we have also listed typical payback periods. Our findings suggest that given available technology, there are still opportunities to reduce energy consumption cost-effectively in the brewing industry. Brewers value highly the quality, taste and drinkability of their beer. Brewing companies have and are expected to continue to spend capital on cost-effective energy conservation measures that meet these quality, taste and drinkability requirements. For individual plants, further research on the economics of the measures, as well as their applicability to different brewing practices, is needed to assess implementation of selected technologies.

    2010-12-22

    This study examines the characteristics of cement plants and their ability to shed or shift load to participate in demand response (DR). Relevant factors investigated include the various equipment and processes used to make cement, the operational limitations cement plants are subject to, and the quantities and sources of energy used in the cement-making process. Opportunities for energy efficiency improvements are also reviewed. The results suggest that cement plants are good candidates for DR participation. The cement industry consumes over 400 trillion Btu of energy annually in the United States, and consumes over 150 MW of electricity in California alone. The chemical reactions required to make cement occur only in the cement kiln, and intermediate products are routinely stored between processing stages without negative effects. Cement plants also operate continuously for months at a time between shutdowns, allowing flexibility in operational scheduling. In addition, several examples of cement plants altering their electricity consumption based on utility incentives are discussed. Further study is needed to determine the practical potential for automated demand response (Auto-DR) and to investigate the magnitude and shape of achievable sheds and shifts.

    Some US renewable energy industries are now looking abroad, especially to the rapidly developing Asia-Pacific region, in order to increase sales and expand markets. The developing world appears in principle to be an important market for renewable energy technologies. These international markets have proven extremely difficult to penetrate, and the US competitive position is threatened by strong, well-organized, government-supported competition from Japan and Western Europe. For example, US photovoltaic manufacturers held 80% of the world PV market in 1980; today their market share is down to 35%. Less developed countries (LDCs) present a potentially significant but highly elusive market for renewable energy technologies. This market may develop for three major reasons; the shortage of electricity supply and the high cost of grid extension to rural areas, the high cost of oil imports and the scarcity of light oil products, and the gradual replacement of traditional fuels with modern ones. The focus of this report is on the policies and attitudes of national and regional governments in India and Pakistan towards renewable energy technology and how these policies and attitudes affect the potential for penetration of these markets by US industry. We have attempted to provide some useful insight into the actual market environment in India and Pakistan rather than just report on official laws, regulations, and policies. The report also examines the economics of technologies in comparison with more traditional sources of energy. It concentrates primarily on technologies, such as photovoltaics and wind electric systems, that would benefit from foreign participation, but also identifies potential market opportunities for advanced solar desalination and other renewable energy technologies. 31 refs.

    Emerging fossil energy power generation systems must operate with unprecedented efficiency and near-zero emissions, while optimizing profitably amid cost fluctuations for raw materials, finished products, and energy. To help address these challenges, the fossil energy industry will have to rely increasingly on the use advanced computational tools for modeling and simulating complex process systems. In this paper, we present the computational research challenges and opportunities for the optimization of fossil energy power generation systems across the plant lifecycle from process synthesis and design to plant operations. We also look beyond the plant gates to discuss research challenges and opportunities for enterprise-wide optimization, including planning, scheduling, and supply chain technologies.

  11. Energy scavenging sources for biomedical sensors.

    Romero, E; Warrington, R O; Neuman, M R

    2009-09-01

    Energy scavenging has increasingly become an interesting option for powering electronic devices because of the almost infinite lifetime and the non-dependence on fuels for energy generation. Moreover, the rise of wireless technologies promises new applications in medical monitoring systems, but these still face limitations due to battery lifetime and size. A trade-off of these two factors has typically governed the size, useful life and capabilities of an autonomous system. Energy generation from sources such as motion, light and temperature gradients has been established as commercially viable alternatives to batteries for human-powered flashlights, solar calculators, radio receivers and thermal-powered wristwatches, among others. Research on energy harvesting from human activities has also addressed the feasibility of powering wearable or implantable systems. Biomedical sensors can take advantage of human-based activities as the energy source for energy scavengers. This review describes the state of the art of energy scavenging technologies for powering sensors and instrumentation of physiological variables. After a short description of the human power and the energy generation limits, the different transduction mechanisms, recent developments and challenges faced are reviewed and discussed.

    2007-09-01

    As the power requirements for modern electronics continue to decrease, many devices which were once dependent on wired power are now being implemented as portable devices operating from self-contained power sources. The most prominent source of portable power is the electrochemical battery, which converts chemical energy into electricity. However, long lasting batteries require large amounts of space for chemical storage, and inevitably require replacement when the chemical reaction no longer takes place. There are many transducers and scavenging energy sources (SES) that are able to exploit their environment to generate low levels of electrical power over a long-term time period, including photovoltaic cells, thermoelectric generators, thermionic generators, and kinetic/piezoelectric power generators. This generated power is sustainable as long as specific environmental conditions exist and also does not require the large volume of a long lifetime battery. In addition to the required voltage generation, stable power conversion requires excess energy to be efficiently stored in an ultracapacitor or similar device and monitoring control algorithms to be implemented, while computer modeling and simulation can be used to complement experimental testing. However, building an efficient and stable power source scavenged from a varying input source is challenging.

    When the suitability of a settlement area is investigated, soil-amplification, liquefaction and fault-related hazards should be defined, and the associated risks should be clarified. For this reason, soil engineering parameters and subsurface geological structure of a new settlement area should be investigated. Especially, faults covered with quaternary alluvium; thicknesses, shear-wave velocities and geometry of subsurface sediments could lead to a soil amplification during an earthquake. Likewise, changes in shear-wave velocities along the basin are also very important. Geophysical methods can be used to determine the local soil properties. In this study, use of alternative seismic energy sources when implementing seismic reflection, seismic refraction and MASW methods in the residential areas of Eskisehir/Turkey, were discussed. Our home developed seismic energy source, EAPSG (Electrically-Fired-PS-Gun), capable to shoot 2x24 magnum shotgun cartridges at once to generate P and S waves; and our home developed WD-500 (500 kg Weight Drop) seismic energy source, mounted on a truck, were developed under a scientific research project of Anadolu University. We were able to reach up to penetration depths of 1200 m for EAPSG, and 800 m for WD-500 in our seismic reflection surveys. WD-500 seismic energy source was also used to perform MASW surveys, using 24-channel, 10 m apart, 4.5 Hz vertical geophone configuration. We were able to reach 100 m of penetration depth in MASW surveys.

  18. Locally Appropriate Energy Strategies for the Developing World: A focus on Clean Energy Opportunities in Borneo

    NASA Astrophysics Data System (ADS)

    Shirley, Rebekah Grace

    This dissertation focuses on an integration of energy modeling tools to explore energy transition pathways for emerging economies. The spate of growth in the global South has led to a global energy transition, evidenced in part by a surge in the development of large scale energy infrastructure projects for the provision of reliable electricity service. The rational of energy security and exigency often usher these large scale projects through to implementation with minimal analysis of costs: social and environmental impact, ecological risk, or opportunity costs of alternative energy transition pathways foregone. Furthermore, development of energy infrastructure is inherently characterized by the involvement of a number of state and non-state actors, with varying interests, objectives and access to authority. Being woven through and into social institutions necessarily impacts the design, control and functionality of infrastructure. In this dissertation I therefore conceptualize energy infrastructure as lying at the intersection, or nexus, of people, the environment and energy security. I argue that energy infrastructure plans and policy should, and can, be informed by each of these fields of influence in order to appropriately satisfy local development needs. This case study explores the socio-techno-environmental context of contemporary mega-dam development in northern Borneo. I describe the key actors of an ongoing mega-dam debate and the constellation of their interaction. This highlights the role that information may play in public discourse and lends insight into how inertia in the established system may stymie technological evolution. I then use a combination of power system simulation, ecological modeling and spatial analysis to analyze the potential for, and costs and tradeoffs of, future energy scenarios. In this way I demonstrate reproducible methods that can support energy infrastructure decision making by directly addressing data limitation barriers. I

    1983-01-01

    Our ability to make underground mines a safe place to work will be a major concern to those seeking to use coal as an energy source. Increased production will stimulate a heightened concern for making mining a more effective energy resource. This effectiveness means that unless safe performance is achieved, the cost of poor safety, such as loss of lives and costly delays due to breakdowns and other failures, will greatly reduce productivity of underground mining operations. As such, coal companies and miners must be prepared to safely manage their operation before underground mining makes a significant effect on energy independence.

    The U.S. pharmaceutical industry consumes almost $1 billion in energy annually. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. pharmaceutical industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy efficient technologies that can be implemented at the component, process, system, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. pharmaceutical industry is provided along with a description of the major process steps in the pharmaceutical manufacturing process. Expected savings in energy and energy-related costs are given for many energy efficiency measures, based on case study data from real-world applications in pharmaceutical and related facilities worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers reduce energy consumption in a cost-effective manner while meeting regulatory requirements and maintaining the quality of products manufactured. At individual plants, further research on the economics of the measures?as well as their applicability to different production practices?is needed to assess potential implementation of selected technologies.

    Predominant forms of food and energy systems pose multiple challenges to the environment as current configurations tend to be structured around centralized one-way through-put of materials and energy. One proposed form of system transformation involves locally integrating "unclosed" material and energy loops from food and energy systems. Such systems, which have been termed integrated food-energy systems (IFES), have existed in diverse niche forms but have not been systematically studied with respect to technological, governance, and environmental differences. This is likely because IFES can have widely different configurations, from co-located renewable energy production on cropland to agroforestry. As a first step in creating a synthesis of IFES, our research team constructed a taxonomy using exploratory data analysis of diverse IFES cases (Gerst et al., 2015, ES&T 49:734-741). It was found that IFES may be categorized by type of primary product produced (plant- or animal-based food or energy) and the degree and direction of vertical supply chain coordination. To further explore these implications, we have begun a study of a highly-coordinated, animal-driven IFES: dairy farms with biogas production from anaerobic digestion of manure. The objectives of the research are to understand the barriers to adoption and the potential benefits to the farms financial resilience and to the environment. To address these objectives, we are interviewing 50 farms across New York and Vermont, collecting information on farmer decision-making and farm operation. These results will be used to calibrate biophysical and economic models of the farm in order understand the future conditions under which adoption of an IFES is beneficial.

    Kansas produces both conventional energy (oil, gas, and coal) and nonconventional (coalbed gas, wind, hydropower, nuclear, geothermal, solar, and biofuels) and ranks the 22nd in state energy production in the U. S. Nonrenewable conventional petroleum is the most important energy source with nonrenewable, nonconventional coalbed methane gas becoming increasingly important. Many stratigraphic units produce oil and/or gas somewhere in the state with the exception of the Salina Basin in north-central Kansas. Coalbed methane is produced from shallow wells drilled into the thin coal units in southeastern Kansas. At present, only two surface coal mines are active in southeastern Kansas. Although Kansas has been a major exporter of energy in the past (it ranked first in oil production in 1916), now, it is an energy importer. ?? 2011 International Association for Mathematical Geology.

    State recycling legislation represents one of the barriers to using wood wastes for energy. Although many states are setting recycling goals that often mandate a significant portion of the waste stream be recycled, legislation in the same states specifically excludes wood-to-energy as a recycling option. A significant supply of yard waste and wood waste could be available for biomass power generation of recycling legislation credited the use of wood-to-energy as an acceptable recycling alternative. This article discusses in some detail the approach Florida legislation has pursued. It could be a model for other innovative recycling programs.

    Thirty-eight studies of energy conservation research opportunities are reviewed. The 38 studies chosen for review include many of the major efforts in the identification of energy conservation research and development (R and D) opportunities and provide a representative sample of the types of studies that have been performed. The sample includes studies that focus on specific energy use (e.g., auto transport), as well as studies that focus on specific types of research (e.g., materials science). The sample also includes studies that can be further contrasted in terms of long-term vs. short-term projects, evolutionary vs. revolutionary ideas, generic vs. process-specific activities, and technology base research vs. hardware development. Each of these perspectives contributes toward assuring coverage of the breadth of energy conservation R and D opportunities. In each review the technical or end-use focus is described, the research ideas identified in the study are listed, and a critical summary is given. The reviews also indicate whether the studies present end-use consumption data, estimate potential energy savings, estimate times to commercialization, summarize existing research programs, or describe the identification methodology. In Section 2.0 the various research studies are compared. In Section 3.0 the characteristics of an aggregate list of research ideas are discussed. The characteristics were collected from the research opportunities studies, which are included in Appendix A. Appendix A contains a compilation of energy conservation R and D opportunities arranged by energy end-use applications. Appendix B contains an outline of the format followed in writing the critical reviews of the studies, the individual study reviews, and the extended bibliography of 88 studies that describe energy conservation research opportunities.

    The following paper sets forth the current understanding of the US clean energy demand and opportunity. As clean energy systems come online and technology is developed, modeling and simulation of these complex energy programs provides an untapped business opportunity. The US Department of Defense provides a great venue for developing new technology in the energy sector because it is demanding lower fuel costs, more energy efficiencies in its buildings and bases, and overall improvements in its carbon footprint. These issues coupled with the security issues faced by foreign dependence on oil will soon bring more clean energy innovations to the forefront (lighter batteries for soldiers, alternative fuel for jets, energy storage systems for ships, etc).

    Optofluidics is a rapidly advancing field that utilizes the integration of optics and microfluidics to provide a number of novel functionalities in microsystems. In this review, we discuss how this approach can potentially be applied to address some of the greatest challenges facing both the developing and developed world, including healthcare, food shortages, malnutrition, water purification, and energy. While medical diagnostics has received most of the attention to date, here we show that some other areas can also potentially benefit from optofluidic technology. Whenever possible we briefly describe how microsystems are currently used to address these problems and then explain why and how optofluidics can provide better solutions. The focus of the article is on the applications of optofluidic techniques in low-resource settings, but we also emphasize that some of these techniques, such as those related to food production, food safety assessment, nutrition monitoring, and energy production, could be very useful in well-developed areas as well.

    CMAS is an intensive user of electricity for lighting because of its size, lack of daylight, and 24-hour operating schedule. Argonne National Laboratory recently conducted a lighting energy conservation evaluation at CMAS. The evaluation included inspection and characterization of existing lighting systems, analysis of energy-efficient retrofit options, and investigation of the environmental effects that these lighting system retrofits could have when they are ready to be disposed of as waste. Argonne devised three retrofit options for the existing lighting systems at various buildings: (1) minimal retrofit--limited fixture replacement; (2) moderate retrofit--more extensive fixture replacement and limited application of motion detectors; and (3) advanced retrofit--fixture replacement, reduction in the number of lamps, expansion of task lighting, and more extensive application of motion detectors. Argonne used data on electricity consumption to analyze the economic and energy effects of these three retrofit options. It performed a cost analysis for each retrofit option in terms of payback. The analysis showed that lighting retrofits result in savings because they reduce electricity consumption, cooling load, and maintenance costs. The payback period for all retrofit options was found to be less than 2 years, with the payback period decreasing for more aggressive retrofits. These short payback periods derived largely from the intensive (24-hours-per-day) use of electric lighting at the facility. Maintenance savings accounted for more than half of the annual energy-related savings under the minimal and moderate retrofit options and slightly less than half of these savings under the advanced retrofit option. Even if maintenance savings were excluded, the payback periods would still be impressive: about 4.4 years for the minimal retrofit option and 2 years for the advanced option. The local and regional environmental impacts of the three retrofit options were minimal.

    1992-01-01

    The suggestion is made that the energy spectrum from point sources such as galactic black hole candidates (GBHC) and active galactic nuclei (AGN) is universal on the average, irrespective of the species of the emitted particles, photons, nucleons, or others. The similarity between the observed energy spectra of cosmic rays, gamma-rays, and X-rays is discussed. In other words, the existing data for gamma-rays and X-rays seem to support the prediction. The expected data from the Gamma Ray Observatory are to provide a further test.

    2009-05-11

    This report summarizes the Lawrence Berkeley National Laboratory's research to date in characterizing energy efficiency and open automated demand response opportunities for industrial refrigerated warehouses in California. The report describes refrigerated warehouses characteristics, energy use and demand, and control systems. It also discusses energy efficiency and open automated demand response opportunities and provides analysis results from three demand response studies. In addition, several energy efficiency, load management, and demand response case studies are provided for refrigerated warehouses. This study shows that refrigerated warehouses can be excellent candidates for open automated demand response and that facilities which have implemented energy efficiency measures and have centralized control systems are well-suited to shift or shed electrical loads in response to financial incentives, utility bill savings, and/or opportunities to enhance reliability of service. Control technologies installed for energy efficiency and load management purposes can often be adapted for open automated demand response (OpenADR) at little additional cost. These improved controls may prepare facilities to be more receptive to OpenADR due to both increased confidence in the opportunities for controlling energy cost/use and access to the real-time data.

    2015-12-01

    A decentralized energy system is a relatively new approach in the power industry. Decentralized energy systems provide promising opportunities for deploying renewable energy sources locally available as well as for expanding access to clean energy services to remote communities. The electricity system of the future must produce and distribute electricity that is reliable and affordable. To accomplish these goals, both the electricity grid and the existing regulatory system must be smarter. In this paper, the major issues and challenges in distributed systems for smart grid are discussed and future trends are presented. The smart grid technologies and distributed generation systems are explored. A general overview of the comparison of the traditional grid and smart grid is also included.

  7. Real world financing opportunities for energy conservation projects

    1988-01-01

    Do you have the resources, dollars, people expertise and general know-how to do all the energy conservation measures. If you have the funds, do it yourself. Historically you would save more if you hired a private concern because that is the only job the contractor does for you. You have other hats to wear and fires to put out. Using third-party financing can be a good decision based on your specific needs. Procrastination is not the answer - the cost of delay is extensive. Financing energy conservation measures is no different from financing your automobile or home. If the benefits outweigh the negatives, the answer is obvious. Remember, in any case of using private sector financing, your are joining a partnership arrangement. The only way to succeed is to be honest with each other on the front end. There need not be any surprises. Any reputable company will gladly have your attorney evaluate all agreements, amortization schedules, and attachments. Real world financing alternatives will continue to change as the market matures. It's not too good to be true. It is no more than a vehicle to make the efforts of capital improvements streamlined. The money or financing is the catalyst to the project and makes the other areas meld.

    There is a multiplicity of development pathways in which low energy sector emissions are not necessarily associated with low economic growth. However, changes in development pathways can rarely be imposed from the top. On this basis, examples of energy efficiency opportunities to change development pathways toward lower emissions are presented in this paper. We review opportunities at the sectoral and macro level. The potential for action on nonclimate policies that influence energy use and emissions are presented. Examples are drawn from policies already adopted and implemented in the energy sector. The paper discusses relationships between energy efficiency policies and their synergies and tradeoffs with sustainable development and greenhouse gas emissions. It points to ways that energy efficiency could be mainstreamed into devel?opment choices.

    This report outlines the technical barriers, gaps, and opportunities that arise in executing home energy upgrade market delivery approaches, as identified through research conducted by the U.S. Department of Energy's Building America program. The objective of this report is to outline the technical1 barriers, gaps, and opportunities that arise in executing home energy upgrade market delivery approaches, as identified through research conducted by the U.S. Department of Energy's (DOE) Building America program. This information will be used to provide guidance for new research necessary to enable the success of the approaches. Investigation for this report was conducted via publications related to home energy upgrade market delivery approaches, and a series of interviews with subject matter experts (contractors, consultants, program managers, manufacturers, trade organization representatives, and real estate agents). These experts specified technical barriers and gaps, and offered suggestions for how the technical community might address them. The potential benefits of home energy upgrades are many and varied: reduced energy use and costs; improved comfort, durability, and safety; increased property value; and job creation. Nevertheless, home energy upgrades do not comprise a large part of the overall home improvement market. Residential energy efficiency is the most complex climate intervention option to deliver because the market failures are many and transaction costs are high (Climate Change Capital 2009). The key reasons that energy efficiency investment is not being delivered are: (1) The opportunity is highly fragmented; and (2) The energy efficiency assets are nonstatus, low-visibility investments that are not properly valued. There are significant barriers to mobilizing the investment in home energy upgrades, including the 'hassle factor' (the time and effort required to identify and secure improvement works), access to financing, and the opportunity cost of

    The U.S. glass industry is comprised of four primary industry segments--flat glass, container glass, specialty glass, and fiberglass--which together consume $1.6 billion in energy annually. On average, energy costs in the U.S. glass industry account for around 14 percent of total glass production costs. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There is a variety of opportunities available at individual plants in the U.S. glass industry to reduce energy consumption in a cost-effective manner. This Energy Guide discusses energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, system, and organizational levels. A discussion of the trends, structure, and energy consumption characteristics of the U.S. glass industry is provided along with a description of the major process steps in glass manufacturing. Expected savings in energy and energy-related costs are given for many energy efficiency measures, based on case study data from real-world applications in glass production facilities and related industries worldwide. Typical measure payback periods and references to further information in the technical literature are also provided, when available. The information in this Energy Guide is intended to help energy and plant managers in the U.S. glass industry reduce energy consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of the measures--as well on as their applicability to different production practices--is needed to assess potential implementation of selected technologies at individual plants.

    1998-11-01

    Although the U.N. Framework Convention on Climate Change (FCCC) has been signed and ratified by 168 countries, global greenhouse gas (GHG) emissions have increased substantially since the 1992 Rio Summit. In both developing countries (DCs) and industrialized countries (ICs), there has been a need to find mechanisms to facilitate environmentally sound mitigation strategies. This need led to the formation of Activities Implemented Jointly (AIJ) at the first Conference-of the Parties (COP) in 1995. In Article 4A, para 2D, the COP established an AIJ pilot phase in which Annex I (IC) countries would enter into agreements to implement activities jointly with non-Annex I parties. DCs would engage in AIJ on a purely voluntary basis and all AIJ projects should be compatible with and supportive of national environment and development goals. AIJ does not imply GHG reduction commitments by DCs. Neither do all projects undertaken during the pilot phase qualify as a fulfillment of current commitment s of Annex I parties under the COP. The current pilot phase for AIJ ends in the year 2000, a date which may be extended. Current AIJ activities are largely focused on the energy sector. The Nordic countries, for example, feel that the most important potential areas for cooperation in AIJ are fuel conversion, more effective energy production, increased energy efficiency, and reforms in energy-intensive industry (Nordic Council of Ministers, 1995). Denmark does not want to include non-energy sector projects such as carbon sink enhancement projects in the pilot phase (Nordic Council of Ministers, 1995). However, other countries, including the US, have already funded a number of forestry sector projects (Development Alternatives, 1997). Moreover, energy-sector projects involving high technology or capital-intensive technology are often a source of controversy between DCs and ICs regarding the kind of technology transferred and sharing of costs and benefits. Further, the pilot phase

    This report provides a preliminary engineering and economic assessment of five direct use projects using low and moderate temperature geothermal resources. Each project site and end-use application was selected because each has a high potential for successful, near-term (2 to 5 years) commercial development. The report also includes an extensive bibliography, and reference and contact lists. The five projects are: Wendel Agricultural Complex, East Mesa Livestock Complex, East Mesa Vegetable Dehydration Facility, Calapatria Heating District and Bridgeport Heating District. The projects involve actual investors, resource owners, and operators with varying financial commitments for project development. For each project, an implementation plan is defined which identifies major barriers to development and methods to overcome them. All projects were determined to be potentially feasible. Three of the projects cascade heat from a small-scale electric generator to direct use applications. Small-scale electric generation technology (especially in the 0.5 to 3 MW range) has recently evolved to such a degree as to warrant serious consideration. These systems provide a year-round heating load and substantially improve the economic feasibility of most direct use energy projects using geothermal resources above 200/sup 0/F.

    The potential geothermal direct-use energy market and its application to projects in California are assessed. Project identification effort is to be focused on those that have the highest probability for near-term successful commercial operations. Near-term herein means 2 to 5 years for project implementation. Phase I has been focused on defining and assessing: (1) the geothermal direct-use resources that are suitable for near-term utilization; and (2) the generic applications (municipal heating districts, horticultural greenhouse firms, laundries, etc.) that are suitable for near-term projects. Five economic development regions in the state, containing recognized geothermal direct-use resources, have been defined. Thirty-eight direct use resources have been evaluated in these regions. After assessment against pre-selected criteria, twenty-seven have been rated with a priority of I, II or III, thereby qualifying them for further marketing effort. The five areas with a priority of I are summarized. These areas have no perceived impediments to near-term development. Twenty-nine generic categories of applications were assessed against previously selected criteria to determine their near term potential for direct use of geothermal fluids. Some twenty industry, commercial and institutional application categories were rated with a priority of I, II or III and warrant further marketing efforts. The seven categories with a priority of I are listed. These categories were found to have the least impediments to near-term application projects.

  15. Biochar As a Renewable Energy Source

    NASA Astrophysics Data System (ADS)

    Stein, Richard

    2011-11-01

    Biochar is a form of charcoal prepared by heating biomass in limited air. It is porous and has high surface area, maintaining much of the morphology of the biomass. The heat for its preparation arises primarily from burning volatiles emitted upon heating. About half the chemical energy in the biomass is contained in the biochar, about 40% is used for the conversion, and about 10% may be used as a local heat source. The biochar can serve as a soil additive where it acts as a template for the growth of bacteria and fungi which then lead to improved growth of biomass by as much as several hundred percent. It remains inert in the soil for many years. Thus, it sequesters the carbon, originally coming from the carbon dioxide absorbed during the photosynthesis occurring during the growth of the biomass. Its use reduces fertilizer and water needs and to pollution arising from the run-off of fertilizer and emission of noxious vapors. Its use is best done at a local level, close to sources of biomass from farm and forest waste. The Pioneer Valley Biochar Initiative along with the Center of Agriculture of the University of Massachusetts, Amherst is promoting the use of biochar on local farms which reduces their dependence on energy arising from fossil fuel and nuclear sources.

    Ammonia- and nitrite-oxidizing microorganisms are collectively responsible for the aerobic oxidation of ammonia via nitrite to nitrate and have essential roles in the global biogeochemical nitrogen cycle. The physiology of nitrifiers has been intensively studied, and urea and ammonia are the only recognized energy sources that promote the aerobic growth of ammonia-oxidizing bacteria and archaea. Here we report the aerobic growth of a pure culture of the ammonia-oxidizing thaumarchaeote Nitrososphaera gargensis using cyanate as the sole source of energy and reductant; to our knowledge, the first organism known to do so. Cyanate, a potentially important source of reduced nitrogen in aquatic and terrestrial ecosystems, is converted to ammonium and carbon dioxide in Nitrososphaera gargensis by a cyanase enzyme that is induced upon addition of this compound. Within the cyanase gene family, this cyanase is a member of a distinct clade also containing cyanases of nitrite-oxidizing bacteria of the genus Nitrospira. We demonstrate by co-culture experiments that these nitrite oxidizers supply cyanase-lacking ammonia oxidizers with ammonium from cyanate, which is fully nitrified by this microbial consortium through reciprocal feeding. By screening a comprehensive set of more than 3,000 publically available metagenomes from environmental samples, we reveal that cyanase-encoding genes clustering with the cyanases of these nitrifiers are widespread in the environment. Our results demonstrate an unexpected metabolic versatility of nitrifying microorganisms, and suggest a previously unrecognized importance of cyanate in cycling of nitrogen compounds in the environment.

    Constantly growing demand for energy carriers, limitation and irretrievability of their now in use resources have forced to turn in the end of XX century the close attention on searches of the no conventional sources possessing both more significant potential resources, and an opportunity of their constant completion. Sources of the energy carrier of organic carbon most widespread by the Earth resources of gas hydrates are prevailing and by different estimations on the order or exceed resources of hydrocarbon raw material used nowadays more. Gas hydrates - the firm crystal connections formed water (liquid water, an ice, water vapor) and low-molecular waterproof natural gases such as carbohydrates (mainly methane), 2, N2 and others, whose crystal structure effectively compresses gas: each cubic meter of hydrate can yield over 160 m3 of methane. Natural gas hydrates occur on earth in three kinds of environments: deep-water subaquactic regions, permafrost and glacier shields. The current estimates show that the amount of energy in these gas hydrates is twice total fossil fuel reserves, indicating a huge source of energy, which can be exploited in the right economical conditions. Despite of appeal of use gas hydrates as the perspective and ecologically more pure fuel with possessing huge resources, investigation and development of their deposits can lead to a number of the negative consequences connected with hazards arising difficulties for maintenance of their technical and ecological safety of carrying out. Furthermore, these gas hydrates are a safety hazard to drilling operation, as they could become unstable under typical wellborn conditions and produce large quantities of gas. The decomposition of natural gas hydrates in porous media could also be responsible for sub sea landslides and global weather changes. Recent studies show that they might provide an opportunity for CO2 sequestering. Scales of arising problems including Geoethical can change from local up to

  1. Matter sourced anisotropic stress for dark energy

    Usually a dark energy as a perfect fluid is characterized by the ratio of pressure to energy density (w =p /ρ ) and the ratio of their perturbations in its rest frame (cs2=δ p /δ ρ ). However, a dark energy would have other characteristics beyond its equation of state and the effective speed of sound. Here the extra property is the anisotropic stress sourced by matter as a simple extension to the perfect fluid model. At the background level, this anisotropic stress is zero with respect to the cosmological principle, but not at the first-order perturbation. We tested the viability of the existence of this kind of anisotropic stress by using the currently available cosmic observations through the geometrical and dynamical measurements. Using the Markov-chain Monte Carlo method, we found that the upper bounds on the anisotropic stress which enters into the summation of the Newtonian potentials should be of the order O (1 0-3)Δm . We did not find any strong evidence for the existence of this matter-sourced anisotropic stress, even in the 1 σ region.

    2011-04-01

    Energy Recovery Linacs are being considered for applications in present and future light sources. ERLs take advantage of the continuous operation of superconducting rf cavities to accelerate high average current beams with low losses. The electrons can be directed through bends, undulators, and wigglers for high brightness x ray production. They are then decelerated to low energy, recovering power so as to minimize the required rf drive and electrical draw. When this approach is coupled with advanced continuous wave injectors, very high power, ultra-short electron pulse trains of very high brightness can be achieved. This paper will review the status of worldwide programs and discuss the technology challenges to provide such beams for photon production.

    The decreasing availability of fossil fuels emphasizes the need to develop systems which will produce synthetic fuel to substitute for and supplement the natural supply. An important first step in the synthesis of liquid and gaseous fuels is the production of hydrogen. Thermonuclear fusion offers an inexhaustible source of energy for the production of hydrogen from water. Depending on design, electric generation efficiencies of approx. 40 to 60% and hydrogen production efficiencies by high temperature electrolysis of approx. 50 to 70% are projected for fusion reactors using high temperature blankets. Fusion/coal symbiotic systems appear economically promising for the first generation of commercial fusion synfuels plants. Coal production requirements and the environmental effects of large-scale coal usage would be greatly reduced by a fusion/coal system. In the long term, there could be a gradual transition to an inexhaustible energy system based solely on fusion.

    Predictions are made concerning the development of alternative energy sources in the light of the present national energy situation. Particular emphasis is given to the impact of alternative fuels development on aviation fuels. The future outlook for aircraft fuels is that for the near term, there possibly will be no major fuel changes, but minor specification changes may be possible if supplies decrease. In the midterm, a broad cut fuel may be used if current development efforts are successful. As synfuel production levels increase beyond the 1990's there may be some mixtures of petroleum-based and synfuel products with the possibility of some shale distillate and indirect coal liquefaction products near the year 2000.

This solution is composed of three regions separated by the contact surface and the shock front. The innermost region is assumed to be uniform and the outside of the contact surface includes the shocked matter described by self-similar solutions. We analytically derive the applicable range of parameters of this solution from requirements needed to satisfy the boundary conditions. We perform numerical simulations for flows with various values of parameters, some of which reside out of the thus-derived applicable range, and compare the results with the semi-analytic solutions.

    Ammonia- and nitrite-oxidizers are collectively responsible for the aerobic oxidation of ammonia via nitrite to nitrate and play essential roles for the global biogeochemical nitrogen cycle. The physiology of these nitrifying microbes has been intensively studied since the first experiments of Sergei Winogradsky more than a century ago. Urea and ammonia are the only recognized energy sources that promote the aerobic growth of ammonia-oxidizing bacteria and archaea. Here we report the aerobic growth of a pure culture of the ammonia-oxidizing thaumarchaeote Nitrososphaera gargensis1 on cyanate as the sole source of energy and reductant, the first organism known to do so. Cyanate, which is a potentially important source of reduced nitrogen in aquatic and terrestrial ecosystems2, is converted to ammonium and CO2 by this archaeon using a cyanase that is induced upon addition of this compound. Within the cyanase gene family, this cyanase is a member of a distinct clade that also contains cyanases of nitrite-oxidizing bacteria of the genus Nitrospira. We demonstrate by co-culture experiments that these nitrite-oxidizers supply ammonia-oxidizers lacking cyanase with ammonium from cyanate, which is fully nitrified by this consortium through reciprocal feeding. Screening of a comprehensive set of more than 3,000 publically available metagenomes from environmental samples revealed that cyanase-encoding genes clustering with the cyanases of these nitrifiers are widespread in the environment. Our results demonstrate an unexpected metabolic versatility of nitrifying microbes and suggest a previously unrecognized importance of cyanate for N-cycling in the environment. PMID:26222031

    This report summarizes the results and the assumptions used in an analysis of the potential “lost efficiency opportunities” in the buildings sector. These targets of opportunity are those end-uses, applications, practices, and portions of the buildings market which are not currently being addressed, or addressed fully, by the Building Technologies Program (BTP) due to lack of resources. The lost opportunities, while a significant increase in effort and impact in the buildings sector, still represent only a small portion of the full technical potential for energy efficiency in buildings.

  16. Assessing Energy Efficiency Opportunities in US Industrial and Commercial Building Motor Systems

    SciTech Connect

    Rao, Prakash; Sheaffer, Paul; McKane, Aimee; Scheihing, Paul

    2015-09-01

    In 2002, the United States Department of Energy (USDOE) published an energy efficiency assessment of U.S. industrial sector motor systems titled United States Industrial Electric Motor Systems Market Opportunities Assessment. The assessment advanced motor system efficiency by providing a greater understanding of the energy consumption, use characteristics, and energy efficiency improvement potential of industrial sector motor systems in the U.S. Since 2002, regulations such as Minimum Energy Performance Standards, cost reductions for motor system components such as variable frequency drives, system-integrated motor-driven equipment, and awareness programs for motor system energy efficiency have changed the landscape of U.S. motor system energy consumption. To capture the new landscape, the USDOE has initiated a three-year Motor System Market Assessment (MSMA), led by Lawrence Berkeley National Laboratory (LBNL). The MSMA will assess the energy consumption, operational and maintenance characteristics, and efficiency improvement opportunity of U.S. industrial sector and commercial building motor systems. As part of the MSMA, a significant effort is currently underway to conduct field assessments of motor systems from a sample of facilities representative of U.S. commercial and industrial motor system energy consumption. The Field Assessment Plan used for these assessments builds on recent LBNL research presented at EEMODS 2011 and EEMODS 2013 using methods for characterizing and determining regional motor system energy efficiency opportunities. This paper provides an update on the development and progress of the MSMA, focusing on the Field Assessment Plan and the framework for assessing the global supply chain for emerging motors and drive technologies.

    This study revealed that increasing numbers of American Indians are securing jobs at energy projects on or near their reservations, and that tribal governments and individual members are taking greater advantage of business opportunities associated with large-scale development projects. The Navajo and Northern Cheyenne experience show that the most effective strategy available to the tribes in securing jobs and service contracting opportunities in the energy industry is through the inclusion of Indian preference provisions in agreements with energy companies. The Navajo have developed explicit tribal policies and procedures for negotiating such agreements, with the result that Navajo employment in coal and uranium mining and processing operations on or near the reservation is as high as 75% and averages around 20% of the total labor force at these facilities. Eight specific recommendations are included.

  18. Opportunities and barriers for a crop-based energy sector in Ontario

    NASA Astrophysics Data System (ADS)

    Klupfel, Ellen Joanne

    This study investigates the existing opportunities and barriers for expanding the crop-based energy sector in Ontario. The investigation takes place at a time when growing concerns about sustainability---environmental, social, and economic---are encouraging the exploration of alternatives to energy systems based on fossil fuels, and concerns around the future viability of rural communities are making agriculturally-based and rural-based energy production systems attractive to many. To explore opportunities and barriers for the crop-based energy sector, this thesis addresses the question: What is the political-economic context within which the crop-based energy sector operates in Ontario? Taking an institutional approach, the study involved 26 interviews with individuals whose organizations influence Ontario's crop-based energy sector (that includes the biofuels ethanol and biodiesel), developed a model outlining relationships between the crop-based energy sector and other sectors of the economy, as well as the state, and implemented a survey of Ontario Members of Provincial Parliament's perspectives on biofuels. This research examines the balance of power of knowledge, production, security, finance, and technology for Ontario's crop-based energy sector. The overall balance of power currently rests with the petroleum sector. Through force field analysis, the study also identifies the key opportunities and barriers for the growth and development of the biofuels sector. These opportunities include climate change and rural development agendas, and the barriers include the petroleum sector, cost of production, and some sectors of the state. A few overarching conclusions emerge from this research: (1) Change in Ontario's crop-based energy sector is driven foremost by political and economic forces; (2) Climate change is the most significant driving force for the development and expansion of Ontario's crop-based energy sector; (3) Production cost and resistance from the

    1981-06-01

    Sugar cane stands out as a renewable resource for fuel alcohol production, thanks to its unique, highly positive energy balance. It supplies its own processing fuel, bagasse. Net liquid fuel usage is only that consumed on the farm, amounting to a maximum of 0.3 volume per volume of ethanol produced. In some locations, the net liquid fuel consumption of the farm is as low as 0.12 volume/volume produced. This small debit may be offset by generating electric power and by foreseeable processing improvements. In view of the very favorable fuel balance for sugar cane, a decision to employ it as a renewable source of ethanol depends wholly on economic and political factors, which in turn are highly location-dependent.

    Natural gas (all of it domestically produced) was the largest single source of Pakistan's 1980 energy supply, contributing 40.1% of the total, compared with 37.4% for oil, 16.6% for hydroelectricity, 5.6% for coal, and 0.3% for LP-gas, plus a very small amount of nuclear power. In 1979, gas accounted for 37.6% of the total and oil for 38.9%. Eighty percent of Pakistan's total natural gas production of nearly 300 billion CF came from the Sui field in central Pakistan, which is being developed by Pakistan Petroleum Ltd. The balance was produced in Esso's Mari field and the Oil and Gas Development Commission's Sari and Hundi fields.

  3. Using ambient noise and sources of opportunity to estimate environment parameters and improve matched field source detection and localization

    2001-07-01

    This dissertation describes matched field source localization methods in a shallow water ocean waveguide which overcome lack of knowledge of the waveguide properties, whose measurement would otherwise be essential for conventional matched field methods to succeed. Such measurements are typically obtained only at great cost by dedicated measurement platforms, separate and distinct from the sensors used to localize sources. We demonstrate MFP using modes derived from data, the sound speed profile, but no a priori bottom information. We show how mode shapes can be estimated directly from vertical line array data, without a priori knowledge of the environment and without using numerical wavefield models. However, it is difficult to make much headway with modes derived from data, without wave numbers, since only a few modes at a few frequencies may be captured, and only at depths sampled by the array. Using a measured sound speed profile, we derive self-consistent, complete sets of modes, wave numbers and bottom parameters from incomplete modes derived from data. Bottom parameters enable us to calculate modes at all frequencies, not just those at which we derived modes from data. This process is applied to SWellEx-96 experiment data. Modes, wave numbers and bottom parameters are derived from source tow data along one track and MFP based on this information is performed on source tow data along another track.

  4. Opportunity Analysis for Recovering Energy from Industrial Waste Heat and Emissions

    United States industry consumed 32.5 Quads (34,300 PJ) of energy during 2003, which was 33.1% of total U.S. energy consumption (EIA 2003 Annual Energy Review). The U.S. industrial complex yields valuable goods and products. Through its manufacturing processes as well as its abundant energy consumption, it supports a multi-trillion dollar contribution to the gross domestic product and provides millions of jobs in the U.S. each year. Industry also yields waste products directly through its manufacturing processes and indirectly through its energy consumption. These waste products come in two forms, chemical and thermal. Both forms of waste have residual energy values that are not routinely recovered. Recovering and reusing these waste products may represent a significant opportunity to improve the energy efficiency of the U.S. industrial complex. This report was prepared for the U.S. Department of Energy Industrial Technologies Program (DOE-ITP). It analyzes the opportunity to recover chemical emissions and thermal emissions from U.S. industry. It also analyzes the barriers and pathways to more effectively capitalize on these opportunities. A primary part of this analysis was to characterize the quantity and energy value of the emissions. For example, in 2001, the industrial sector emitted 19% of the U.S. greenhouse gases (GHG) through its industrial processes and emitted 11% of GHG through electricity purchased from off-site utilities. Therefore, industry (not including agriculture) was directly and indirectly responsible for emitting 30% of the U.S. GHG. These emissions were mainly comprised of carbon dioxide (CO2), but also contained a wide-variety of CH4 (methane), CO (carbon monoxide), H2 (hydrogen), NMVOC (non-methane volatile organic compound), and other chemicals. As part of this study, we conducted a survey of publicly available literature to determine the amount of energy embedded in the emissions and to identify technology opportunities to capture and

    This study of job opportunities in the energy industry for minority youth (16 to 24 years old) was precipitated by two factors: (1) the unusually high unemployment rate for minority youth in the United States; and (2) the question of whether or not the expanding domestic energy industry offered job opportunities to assist in reducing that high unemployment rate. As recently as March 16, 1981, US Department of Labor Secretary Raymond Donovan expressed the Reagan Administration's determination to tackle the persistent problems of minority teen-age unemployment, which has been running at a national average of 40.8% in 1981, having reached 43% in some urban areas during the years 1976 and 1980. Secretary Donovan emphasized his approach would be to encourage jobs for youth in private industry. Through the development of an analytical model, Minority-Emphasized Regional Demand and Supply Analysis, this study attempts a projection of job opportunities and minority youth availability in the energy industries in 18 energy producing states.

    This white paper surveys DOD installations that could have an increased potential interest in the purchase of energy from renewable energy projects on tribal lands. Identification of likely purchasers of renewable energy is a first step in the energy project development process, and this paper aims to identify likely electricity customers that tribal commercial-scale projects could serve. This white paper builds on a geospatial analysis completed in November 2012 identifying 53 reservations within 10 miles of military bases (DOE 2012). This analysis builds on those findings by further refining the list of potential opportunity sites to 15 reservations (Table ES-1), based on five additional factors: 1) The potential renewable resources required to meet the installation energy loads; 2) Proximity to transmission lines; 3) Military installation energy demand; 4) State electricity prices; 5) Local policy and regulatory environment.

    Agronomists, evaluating tropical grasses from Saccharum and allied genera as potential renewable energy sources for boiler fuel and alcohol, emphasized (1) maximizing sugar cane's total biomass rather than sucrose production, (2) utilizing alternative tropical grasses during sugar cane's offseason for year-round fuel production, and (3) mechanizing production technologies for fibrous, thin-stemmed tropical grasses that are to be managed as solar-dried fuels and feedstocks. Based on the time required to maximize their dry matter yields, three categories of grasses have emerged as potential energy crops: short rotation (2-3 months) with Sordan 70A (a sorghum/sudan grass hybrid), intermediate rotation (4-6 months) with napier grass, and long rotation (12-18 months) with sugar cane. Total oven-dried matter is 50 tons/acre-yr (114 metric tons /hectare-yr) for sugar cane, 33 tons (74 metric tons) from napier grass harvested at 6-month intervals, and 21 tons (47 metric tons) from Sordan 70A harvested every 14 weeks.

    US industry produces about 12 billion tons of waste a year, or two-thirds of the waste generated in the US. The costs of handling and disposing of these wastes are significant, estimated to be between $25 and $43 billion in 1991, and represent an increase of 66% since 1986. US industry also uses about one-third of all energy consumed in the nation, which adds to the environmental burden. Industrial wastes affect the environmental well-being of the nation and, because of their growing costs, the competitive abilities of US industry. As part of a national effort to reduce industrial wastes, the US Congress passed the Energy Policy Act (EPAct, P.L. 102-486). Section 2108, subsections (b) and (c), of EPAct requires the Department of Energy (DOE) to identify opportunities to demonstrate energy efficient pollution prevention technologies and processes; to assess their availability and the energy, environmental, and cost effects of such technologies; and to report the results. Work for this report clearly pointed to two things, that there is insufficient data on wastes and that there is great breadth and diversity in the US industrial sector. This report identifies: information currently available on industrial sector waste streams, opportunities for demonstration of energy efficient pollution prevention technologies in two industries that produce significant amounts of waste--chemicals and petroleum, characteristics of waste reducing and energy saving technologies identifiable in the public literature, and potential barriers to adoption of waste reducing technologies by industry.

    Liberal economic and political reforms in Latin America, a declining oil market in the US, and world events such as last year`s Persian Gulf Crisis are making foreign investment in Latin America`s energy sector increasingly attractive. The Persian Gulf crisis indicated the US must diversify oil sources; increased competition and deregulation in electric power generation and gas production are providing more opportunities for independent power producers at home and abroad; and Latin America`s need for foreign financial and technical assistance are providing an important ``pull`` factor. Electricity needs in the developing world wig be huge in the years to come. In Latin America and the Caribbean, 66,500 mg of new capacity will be required by 1999. The developing world will require US $100 billion in energy investment a year. But Latin American countries will have trouble obtaining funds. The region will need to rely heavily on private international sources to finance future energy requirements. Multilateral development bank participation win remain critical, however, serving as a catalyst for government reform and private investment in the sector. In particular, World Bank lending will be focused on countries with a clear commitment to pricing reform, regulatory reform, competitive markets, non-market barriers, and technology transfer. Opportunities for foreign participation in the Latin American oil sector are particularly large in Ecuador, Peru, Argentina, and Venezuela. Mexico`s plans for reform in the oil sector, a delicate issue in that country, appear to be less defined and likely to occur farther into the future. The conference made clear that a regulatory entity is needed even when the sector is owned by the government. Regulatory processes must be fair and transparent in order to ensure adequate financial and technical performance.

    This analysis is an update to the 2005 Energy Efficiency Potential Study completed by KEMA for the Kauai Island Utility Cooperative (KIUC) and identifies potential energy efficiency opportunities in the residential sector on Kauai (KEMA 2005). The Total Resource Cost (TRC) test is used to determine which of the energy efficiency measures analyzed in the KEMA report are cost effective for KIUC to include in a residential energy efficiency program. This report finds that there remains potential energy efficiency savings that could be cost-effectively incentivized through a utility residential demand-side management program on Kauai if implemented in such a way that the program costs per measure are consistent with the current residential program costs.

    Kramer, Klaas Jan; Masanet, Eric; Worrell, Ernst

    2009-01-01

    The U.S. pulp and paper industry consumes over $7 billion worth of purchased fuels and electricity per year. Energy efficiency improvement is an important way to reduce these costs and to increase predictable earnings, especially in times of high energy price volatility. There are a variety of opportunities available at individual plants in the U.S. pulp and paper industry to reduce energy consumption in a cost-effective manner. This paper provides a brief overview of the U.S. EPA ENERGY STAR(R) for Industry energy efficiency guidebook (a.k.a. the"Energy Guide") for pulp and paper manufacturers. The Energy Guide discusses a wide range of energy efficiency practices and energy-efficient technologies that can be implemented at the component, process, facility, and organizational levels. Also provided is a discussion of the trends, structure, and energy consumption characteristics of the U.S. pulp and paper industry along with a description of the major process technologies used within the industry. Many energy efficiency measure descriptions include expected savings in energy and energy-related costs, based on case study data from real-world applications in pulp and paper mills and related industries worldwide. The information in this Energy Guide is intended to help energy and plant managers in the U.S. pulp and paper industry reduce energy consumption in a cost-effective manner while maintaining the quality of products manufactured. Further research on the economics of all measures?as well as on their applicability to different production practices?is needed to assess their cost effectiveness at individual plants.

    Nonrenewable sources are subject to intertemporal optimization. Electrical and renewable sources, which are exogenous, can be integrated and treated on nonrenewable sources. For typical conditions, the model predicts that prices will increase and flows will fall more abruptly than is generally expected. These trends are exacerbated by limits on renewable sources. Predicted price trajectories should permit the introduction of alternative fuels if available, but their late introduction could be costly. Greater imports do not appear likely or appropriate. 17 refs., 24 figs.

    Traditionally, renewable biomass energy sources comprise forests, agriculture and other large vegetation units. With the increasing demand on those landscape elements, including conflicts of interest to nature conservation and food production, the research focus should also incorporate smaller vegetation entities. In this study, we highlight the availability of small-scale features like roadside vegetation or hedges, which are rarely featured in maps. Roadside vegetation, however, is well known and regularly trimmed to allow the passing of traffic but the cut material is rarely harvested. Here, we combine a remote-sensing-based approach to quantify the seasonal biomass harvests with a GIS-based method to outline optimal transportation routes to, and the location of, storage units and power plants. Our main data source will be ESA's upcoming Sentinel-2 optical satellite. Spatial resolution of 10 meters in the visible and near infrared requires the use of spectral unmixing to derive end member spectra of the targeted biomass objects. Additional stereo-matching and LIDAR measurements allow the accompanying height estimate to derive the biomass volume and its changes over time. GIS data bases from the target areas allow the discrimination between traditional, large features (e.g. forests and agriculture) as well as previously unaccounted for, smaller vegetation units. With the mapped biomass occurrence and additional, GIS-based infrastructure information, we can outline transport routes that take into account local restrictions like nature reserve areas, height or weight limitations as well as transport costs in relation to potential gains. This information can then be processed to outline optimal places for power plants. To simulate the upcoming Sentinel-2 data sets, we use airborne data from the AISA Eagle, spatially and spectrally down-sampled to match Sentinel 2's resolution. Our test scenario is an area in western Germany, the Kirchheller Heide, close to the city

  5. Source-separated urine opens golden opportunities for microbial electrochemical technologies.

    The food security of a booming global population demands a continuous and sustainable supply of fertilisers. Their current once-through use [especially of the macronutrients nitrogen (N), phosphorus (P), and potassium (K)] requires a paradigm shift towards recovery and reuse. In the case of source-separated urine, efficient recovery could supply 20% of current macronutrient usage and remove 50-80% of nutrients present in wastewater. However, suitable technology options are needed to allow nutrients to be separated from urine close to the source. Thus far none of the proposed solutions has been widely implemented due to intrinsic limitations. Microbial electrochemical technologies (METs) have proved to be technically and economically viable for N recovery from urine, opening the path for novel decentralised systems focused on nutrient recovery and reuse.

  6. Opportunities to enhance alternative sources of long-chain n-3 fatty acids within the diet.

    Health benefits or advocated health benefits of long-chain (LC) n-3 PUFA are better known by medical doctors as well as by consumers, so that consumption increases. In addition, the development of aquaculture requires more fishmeal and fish oil. Humanisation of care of companion animals is also associated with addition of LC n-3 PUFA in pet foods. The risk of the increased demand for LC n-3 PUFA is the excess harvesting of natural sources, especially of marine origin (oily fishes, krill). In order to improve sustainability, alternative sources of LC n-3 PUFA have been developed. These alternative sources are: (a) terrestrial plants naturally or genetically enriched in stearidonic acid (SDA), which bypasses the first limiting step of (i.e. ∆6 desaturase) of the biosynthesis of LC n-3 PUFA; (b) single-cell oils rich in LC n-3 PUFA (microalgae, Escherichia coli) and krill. Currently, plants rich in SDA are expensive, metabolic engineering is unfavourably accepted by consumers in many countries, cultivation of microalgae is very expensive even though their ability (for some of them) to synthesise biofuels could induce a decrease in industrial costs, and Antarctic krill harvest must be restricted. Thus, it is difficult to predict their real development in the future. PMID:24886839

    Replacing inefficient kerosene lighting with electric lighting or other clean alternatives can rapidly achieve development and energy access goals, save money and reduce climate warming. Many of the 250 million households that lack reliable access to electricity rely on inefficient and dangerous simple wick lamps and other kerosene-fueled light sources, using 4 to 25 billion liters of kerosene annually to meet basic lighting needs. Kerosene costs can be a significant household expense and subsidies are expensive. New information on kerosene lamp emissions reveals that their climate impacts are substantial. Eliminating current annual black carbon emissions would provide a climate benefit equivalent to 5 gigatons of carbon dioxide reductions over the next 20 years. Robust and low-cost technologies for supplanting simple wick and other kerosene-fueled lamps exist and are easily distributed and scalable. Improving household lighting offers a low-cost opportunity to improve development, cool the climate and reduce costs.

    A small scale (1 gal/hr) biomass-to-alcohol still was built at the Raft River Geothermal Site to investigate difficulties in geothermal assisted biomass conversion. The unit was successfully operated, producing 95% (190 proof) ethanol from sugar beet juice. The unit was designed and built in less than eight weeks from surplus equipment using commercially available design information. This small-scale still demonstrated that 95% ethanol can be produced from sugar beet beer containing 8 to 10% alcohol using geothermal energy and present commercial technology. The geothermal resource provided both an energy source and process water. Recently, Bechtel National, Incorporated, of San Francisco, California completed a study to analyze the economic feasibility of producing ethanol from potatoes, wheat, and sugar beets using geothermal resources available in the Raft River Region of Idaho. The study concluded that a 20 million gallon per year facility can be built that will supply alcohol at $1.78 per gallon using geothermal energy. (MHR)
