Programs in Renewable Energy  

SciTech Connect

Our nation faces significant challenges as we enter the 1990s: securing a reliable supply of competitively priced energy, improving the quality of our environment, and increasing our share of foreign markets for goods and services. The US Department of Energy's (DOE) Programs in Renewable Energy are working toward meeting these challenges by developing the technologies that make use of our nation's largest energy resource: renewable energy. The sunlight, wind biomass, flowing water, ocean energy, and geothermal energy that make up the renewable energy resource can be found throughout our nation. These resources can provide all the forms of energy our nation needs: liquid fuels, electricity, and heating and cooling. Renewable energy meets about 10% of our need for these forms of energy today, yet the potential contribution is many times greater. DOE's Programs in Renewable Energy are working side-by-side with American industry to develop the technologies that convert renewable energy resources into practical, cost-competitive energy. After a decade of progress in research, several of these technologies are poised to make large contributions during the 1990s and beyond. This booklet provides an overview of the renewable energy programs and their plans for FY 1990. Sources of additional information are listed at the back of the booklet. 48 figs., 4 tabs.

Integrated renewable energy systems  

SciTech Connect

Utilization of several manifestations of solar energy in tandem by means of integrated renewable energy systems (IRES) to supply a variety of energy and other needs has the potential to energize (in contrast to electrification) remote rural areas in a cost-effective manner. Such actions can dramatically improve the quality of life for hundreds of millions of people living in remote villages in the continents of Asia, Africa, and Latin America. The environmentally benign nature of renewable resource utilization and the potability of exploiting locally available resources with the consequent growth of job opportunities are some of the many benefits that can accrue by the deployment of IRES. Even small amounts of energy can be very beneficial in remote rural areas of developing countries with no grid connection as compared to the massive urban sprawls in both developed and developing countries. A concerted global effort in this direction can build the much-needed market potential for renewables now, resulting in future cost reductions.

Reducing theatre energy consumption.  

PubMed

As little has been written to describe the electrical energy required to deliver anaesthesia, we undertook to measure the total electrical energy consumption for a day's clinical anaesthesia. Daily energy consumption related to anaesthesia was measured with commercially available 'plug-in' power and energy meters, and additional in-use energy estimates were based on direct observation made in theatre and from measuring the power consumption of anaesthetic gas scavenging system (AGSS) pumps. Total energy use for anaesthesia per day was 28 kWh, and cost the modest sum of around pound 2.24 per day. Disproportionately large amounts of energy were required to run the anaesthetic gas scavenging pumps and the overhead radiant heaters. Energy saving can be safely obtained by switching off AGSS out of hours, and placing radiant heaters on timing or thermostatic controls. PMID:24697094

Will Renewable Energy Save Our Planet?  

NASA Astrophysics Data System (ADS)

This paper discusses some important fundamental issues behind application of renewable energy (RE) to evaluate its impact as a climate change mitigation technology. The discussed issues are the following: definition of renewable energy, concentration of RE by weight and volume, generation of electrical energy and its power at unit area, electrical energy demand per unit area, life time approach vs. layman approach, energy return time, energy return ratio, CO2 return time, energy mix for RES production and use, geographical distribution of RES use, huge scale of energy shift from RES to non-RES, increase in energy consumption, Thermodynamic equilibrium of earth, and probable solutions for energy future of our energy and environmental crisis of today. The future solution (that would enable to human civilization further welfare, and good living, but with lower release of CO2 in atmosphere) may not be only RES. This will rather be an energy mix that may contain nuclear energy, non-nuclear renewable energy, or fossil energy with CO2 sequestration, efficient energy technologies, energy saving, and energy consumption decrease.

Renewable energy is now a mainstream concern among businesses and governments across the world, and could be considered a characteristic preoccupation of our time. It is interesting to note that many of the energy technologies currently being developed date back to very different eras, and even predate the industrial revolution. The fuel cell was first invented as long ago as 1838 by the Swiss--German chemist Christian Friedrich Schönbein [1], and the idea of harnessing solar power dates back to ancient Greece [2]. The enduring fascination with new means of harnessing energy is no doubt linked to man's innate delight in expending it, whether it be to satisfy the drive of curiosity, or from a hunger for entertainment, or to power automated labour-saving devices. But this must be galvanized by the sustained ability to improve device performance, unearthing original science, and asking new questions, for example regarding the durability of photovoltaic devices [3]. As in so many fields, advances in hydrogen storage technology for fuel cells have benefited significantly from nanotechnology. The idea is that the kinetics of hydrogen uptake and release may be reduced by decreasing the particle size. An understanding of how effective this may be has been hampered by limited knowledge of the way the thermodynamics are affected by atom or molecule cluster size. Detailed calculations of individual atoms in clusters are limited by computational resources as to the number of atoms that can studied, and other innovative approaches that deal with force fields derived by extrapolating the difference between the properties of clusters and bulk matter require labour-intensive modifications when extending such studies to new materials. In [4], researchers in the US use an alternative approach, considering the nanoparticle as having the same crystal structure as the bulk but relaxing the few layers of atoms near the surface. The favourable features of nanostructures for catalysis also recommend them for ethanol fuel cells, as demonstrated in the decoration of SnO2-coated single-walled carbon nanotubes with platinum catalysts by researchers in Canada [5] Interest in solar power received an enormous boost in the early 1990s when Brian O'Regan and Michael Grätzel published work on a new way to maximise the amount of energy harvested by colloidal TiO2 films with the use of a charge-transfer dye [6]. This approach captured attention across the community due to the large current densities, exceptional stability and low cost of the devices. This design has been modified since, using arrays of nanowires, where each nanowire provides a direct pathway to the collection electrode. In [7], researchers in the US investigate how arrays of vertical nanowires with controlled aspect ratios grow in solution, and how the nanowire aspect ratio affects the performance of nanowire-based dye-sensitized solar cells. A collaboration of researchers in China and Australia has considered how the cell performance could be improved by maximising the interface area between the indium-tin-oxide (ITO)-glass electrode and the oxide semiconductor. To this end, they synthesized arrays of ITO nanowires and ITO/TiO2 core-shell nanowires creating a three-dimensional electrode [8]. Quantum dots have also been incorporated into solar cell devices as they have higher extinction coefficients than metal-organic dyes and their size-dependent spectral responses allow them to be tuned to optimize their performance. Until recently, molecular linkers have been required to attach the quantum dots to the electrode, creating a gap between quantum dot and electrode that is thought to diminish cell performance. Researchers in Spain and Japan have applied a new technique that allows the quantum dots to be adsorbed directly onto the electrode, yielding significant improvements to cell efficiency [9]. Organic photovoltaic devices have also attracted considerable interest as a result of their flexibility and the ability to produce them at a low cost in large scales. While maximising cell effici

Per Capita Energy Consumption  

NSDL National Science Digital Library

Chart ranking states by per capita energy consumption shows it to be an almost perfect inverse of population density. Could be used in a course dealing with energy policy or as a crossover in many other course. Might be especially interesting, for instance, in a course about governing institutions at their consequences on policy using the uneven representation in the United States Senate and the uncertain future of the cap-and-trade climate bill to demonstrate the importance of institutions.

Annual renewable energy technology review  

SciTech Connect

The Renewable Energy Institute has seen a growing need to provide a central source of information on the full range of renewable energy technologies. Inquiries from federal and state governments, colleges and universities, renewable energy companies, foreign companies and governments, journalists, and the general public have revealed that such an information source was sorely lacking. National energy statistics generally identify only the ''tip of the iceberg'' by surveying traditional supply sources (e.g. electric utilities) and group the renewable energy contribution into the ''other'' category. Because of their decentralized application, the direct contribution of these technologies and their displacement of conventional energy sources are often overlooked. The Annual Renewable Energy Technology Review: Progress Through 1984 marks the second effort by the Renewable Energy Institute to quantify the contribution of renewable energy. The publication has been greatly expanded from the previous edition. Information on total resources availability, international activities, and state government incentives has been added. Also, sections which appeared in the previous edition on technology status, industry status, and market status have been enhanced to provide readers with vital information for evaluating the status and prospects of each technology.

Developing Government Renewable Energy Projects  

SciTech Connect

The US Army Corps of Engineers has retained Idaho National Laboratory (INL) to conduct a study of past INL experiences and complete a report that identifies the processes that are needed for the development of renewable energy projects on government properties. The INL has always maintained expertise in power systems and applied engineering and INL’s renewable energy experiences date back to the 1980’s when our engineers began performing US Air Force wind energy feasibility studies and development projects. Over the last 20+ years of working with Department of Defense and other government agencies to study, design, and build government renewable projects, INL has experienced the do’s and don’ts for being successful with a project. These compiled guidelines for government renewable energy projects could include wind, hydro, geothermal, solar, biomass, or a variety of hybrid systems; however, for the purpose of narrowing the focus of this report, wind projects are the main topic discussed throughout this report. It is our thought that a lot of what is discussed could be applied, possibly with some modifications, to other areas of renewable energy. It is also important to note that individual projects (regardless the type) vary to some degree depending on location, size, and need but in general these concepts and directions can be carried over to the majority of government renewable energy projects. This report focuses on the initial development that needs to occur for any project to be a successful government renewable energy project.

Renewable Energy: Energy Security and Sustainability  

NASA Astrophysics Data System (ADS)

Renewable energy offers the possibility of providing a complete, sustainable energy infrastructure without anthropogenic emission of CO2. Large-scale implementation of renewable technologies would eliminate the need to develop and implement sequestration systems, by reducing the use of, and ultimately eliminating fossil based energy production. Renewable energy also offers energy security because indigenous resources are sufficient. The major renewable energy systems include phovoltaics (solar cells), solar thermal (electric and thermal), wind, biomass (plants and trees), hydroelectric, ocean, and geothermal. Given the intermittent nature of solar energy, only those energy systems that are coupled to an energy storage technology will be viable. Among the energy storage technologies are hydrogen, batteries, flywheels, superconductivity, ultracapacitors, pumped hydro, molten salts (for thermal storage), and compressed gas. One of the most versatile energy storage systems and the best energy carrier for transportation is hydrogen. This talk will review some of the basic renewable energy systems, present possible pathways for the implementation of hydrogen into the energy infrastructure and offer research areas that need to be addressed to increase the viability of these renewable energy technologies.

The potential of renewable energy  

SciTech Connect

On June 27 and 28, 1989, the US Department of Energy (DOE) national laboratories were convened to discuss plans for the development of a National Energy Strategy (NES) and, in particular, the analytic needs in support of NES that could be addressed by the laboratories. As a result of that meeting, interlaboratory teams were formed to produce analytic white papers on key topics, and a lead laboratory was designated for each core laboratory team. The broad-ranging renewables assignment is summarized by the following issue statement from the Office of Policy, Planning and Analysis: to what extent can renewable energy technologies contribute to diversifying sources of energy supply What are the major barriers to greater renewable energy use and what is the potential timing of widespread commercialization for various categories of applications This report presents the results of the intensive activity initiated by the June 1989 meeting to produce a white paper on renewable energy.

Energy Efficiency and Importance of Renewable Energy Sources in Latvia  

NASA Astrophysics Data System (ADS)

The main goal of Latvian energy policy is to ensure safe and environmentally friendly long-term energy supply at cost-effective prices, contributing to enhance competitiveness, and to ensure safe energy transit. The Latvian Parliament approved an Energy Efficiency Strategy in 2000. Its objective is to decrease energy consumption per unit of GDP by 25% by 2010. Awareness raising, implementation of standards and economic incentives for self financing are the main instruments to increase energy efficiency, mentioned in the strategy. Latvia, as many other European Union member states, is dependent on the import of primary energy resources. The Latvian Renewable Energy strategy is still under development. The only recent study on RES was developed in the framework of a PHARE program in year 2000: "Renewable energy resource program", where three main objectives for a future RES strategy were proposed: 1. To increase the use of wood waste and low value wood and forest residues. 2. To improve efficiency of combustion technologies and to replace outdated plants. 3. To increase the use of renewables in Combined Heat and Power plants (CHP). Through the Renewable Energy and Energy Efficiency Partnership, partners will develop a set of new shared activities, and coordinate and strengthen existing efforts in this area.

Analysis and Optimization of Building Energy Consumption  

NASA Astrophysics Data System (ADS)

Energy is one of the most important resources required by modern human society. In 2010, energy expenditures represented 10% of global gross domestic product (GDP). By 2035, global energy consumption is expected to increase by more than 50% from current levels. The increased pace of global energy consumption leads to significant environmental and socioeconomic issues: (i) carbon emissions, from the burning of fossil fuels for energy, contribute to global warming, and (ii) increased energy expenditures lead to reduced standard of living. Efficient use of energy, through energy conservation measures, is an important step toward mitigating these effects. Residential and commercial buildings represent a prime target for energy conservation, comprising 21% of global energy consumption and 40% of the total energy consumption in the United States. This thesis describes techniques for the analysis and optimization of building energy consumption. The thesis focuses on building retrofits and building energy simulation as key areas in building energy optimization and analysis. The thesis first discusses and evaluates building-level renewable energy generation as a solution toward building energy optimization. The thesis next describes a novel heating system, called localized heating. Under localized heating, building occupants are heated individually by directed radiant heaters, resulting in a considerably reduced heated space and significant heating energy savings. To support localized heating, a minimally-intrusive indoor occupant positioning system is described. The thesis then discusses occupant-level sensing (OLS) as the next frontier in building energy optimization. OLS captures the exact environmental conditions faced by each building occupant, using sensors that are carried by all building occupants. The information provided by OLS enables fine-grained optimization for unprecedented levels of energy efficiency and occupant comfort. The thesis also describes a retrofit-oriented building energy simulator, ROBESim, that natively supports building retrofits. ROBESim extends existing building energy simulators by providing a platform for the analysis of novel retrofits, in addition to simulating existing retrofits. Using ROBESim, retrofits can be automatically applied to buildings, obviating the need for users to manually update building characteristics for comparisons between different building retrofits. ROBESim also includes several ease-of-use enhancements to support users of all experience levels.

Renewable Energy Resources in Lebanon  

NASA Astrophysics Data System (ADS)

The energy sector in Lebanon plays an important role in the overall development of the country, especially that it suffers from many serious problems. The fact that Lebanon is among the few countries that are not endowed with fossil fuels in the Middle East made this sector cause one third of the national debt in Lebanon. Despite the large government investments in the power sector, demand still exceeds supply and Lebanon frequently goes through black out in peak demand times or has to resort to importing electricity from Syria. The Energy production sector has dramatic environmental and economical impacts in the form of emitted gasses and environment sabotage, accordingly, it is imperative that renewable energy (RE) be looked at as an alternative energy source. Officials at the Ministry of Energy and Water (MEW) and Lebanese Electricity (EDL) have repeatedly expressed their support to renewable energy utilization. So far, only very few renewable energy applications can be observed over the country. Major efforts are still needed to overcome this situation and promote the use of renewable energy. These efforts are the shared responsibility of the government, EDL, NGO's and educational and research centers. Additionally, some efforts are being made by some international organizations such as UNDP, ESCWA, EC and other donor agencies operating in Lebanon. This work reviews the status of Energy in Lebanon, the installed RE projects, and the potential projects. It also reviews the stakeholders in the field of RE in Lebanon Conclusion In considering the best R.E. alternative, it is important to consider all potential R.E. sources, their costs, market availability, suitability for the selected location, significance of the energy produced and return on investment. Several RE resources in Lebanon have been investigated; Tides and waves energy is limited and not suitable two tentative sites for geothermal energy are available but not used. Biomass resources badly affect the environment with the current technology and it is preferred to go for recycling. Limited hydropower plants are already installed and there are plans for new projects. Small wind turbines found their way in the market for individuals living in the rural areas that suffer from blackouts the most to replace the fuel stand alone generators. Solar PV is still immature however projects like street lighting in the south were successfully achieved. Solar thermal power is the most suitable for water heating in and outside the residential areas. Projects to increase the efficiency like replacing lights with power saving lights and thermal insulation of buildings are funded by several organizations.

Renewable energy - Target for 2050  

NASA Astrophysics Data System (ADS)

The possibilities of various renewable energy technologies to supply a projected world demand for 40,000 GW years of energy each year by the year 2050 are examined. Noting that industrial processes consume 50% of all energy needs, fossil fuel reserves are shown to be sufficient for a maximum of 370 yr in the U.S., when all supplies become depleted. Breeder reactors have a doubling time which is 30 yr too long for meeting more than 0.5% of world energy demand in 2050, while fusion, even considering ocean-derived deuterium as a fuel source, will not be supplying energy for another 35-70 yr. Among the solar technologies, the installation of ten million 100 m tall 4 MW wind generators is feasible to meet all the projected energy needs, and solar cells with 10% conversion efficiency could do the same with 14 times less land. Further discussion is given to geothermal, fuel cell, and OTEC technologies, as well as the forty trillion dollars necessary to erect the fully renewable systems.

Renewable Energy: Solar Fuels GRC and GRS  

SciTech Connect

This Gordon Research Conference seeks to bring together chemists, physicists, materials scientists and biologists to address perhaps the outstanding technical problem of the 21st Century - the efficient, and ultimately economical, storage of energy from carbon-neutral sources. Such an advance would deliver a renewable, environmentally benign energy source for the future. A great technological challenge facing our global future is energy. The generation of energy, the security of its supply, and the environmental consequences of its use are among the world's foremost geopolitical concerns. Fossil fuels - coal, natural gas, and petroleum - supply approximately 90% of the energy consumed today by industrialized nations. An increase in energy supply is vitally needed to bring electric power to the 25% of the world's population that lacks it, to support the industrialization of developing nations, and to sustain economic growth in developed countries. On the geopolitical front, insuring an adequate energy supply is a major security issue for the world, and its importance will grow in proportion to the singular dependence on oil as a primary energy source. Yet, the current approach to energy supply, that of increased fossil fuel exploration coupled with energy conservation, is not scaleable to meet future demands. Rising living standards of a growing world population will cause global energy consumption to increase significantly. Estimates indicate that energy consumption will increase at least two-fold, from our current burn rate of 12.8 TW to 28 - 35 TW by 2050. - U.N. projections indicate that meeting global energy demand in a sustainable fashion by the year 2050 will require a significant fraction of the energy supply to come carbon free sources to stabilize atmospheric carbon dioxide levels at twice the pre-anthropogenic levels. External factors of economy, environment, and security dictate that this global energy need be met by renewable and sustainable sources from a carbon-neutral source. Sunlight is by far the most abundant global carbon-neutral energy resource. More solar energy strikes the surface of the earth in one hour than is obtained from all of the fossil fuels consumed globally in a year. Sunlight may be used to power the planet. However, it is intermittent, and therefore it must be converted to electricity or stored chemical fuel to be used on a large scale. The 'grand challenge' of using the sun as a future energy source faces daunting challenges - large expanses of fundamental science and technology await discovery. A viable solar energy conversion scheme must result in a 10-50 fold decrease in the cost-to-efficiency ratio for the production of stored fuels, and must be stable and robust for a 20-30 year period. To reduce the cost of installed solar energy conversion systems to $0.20/peak watt of solar radiation, a cost level that would make them economically attractive in today's energy market, will require revolutionary technologies. This GRC seeks to present a forum for the underlying science needed to permit future generations to use the sun as a renewable and sustainable primary energy source. Speakers will discuss recent advances in homoogeneous and heterogeneous catalysis of multi-electron transfer processes of importance to solar fuel production, such as water oxidation and reduction, and carbon dioxide reduction. Speakers will also discuss advances in scaleably manufacturable systems for the capture and conversion of sunlight into electrical charges that can be readily coupled into, and utilized for, fuel production in an integrated system.

The subject of this paper is innovative policies to promote renewable energy. The renewable energy industry has made great progress in the last decade. Prices have dropped four-fold or more, and reliability has increased dramatically. By most measures, then, the renewable energy industry should be poised to become a mainstream success. But upon closer examination, it appears instead that our society may snatch defeat from the jaws of victory. Unless something changes, and soon, we will watch dozens of promising renewable technologies stumble and fail. This paper examines what drives this ironic situation, where on the one hand our renewable energy technologies are more cost-effective than ever, and on the other our society is not yet poised to purchase them in sufficient quantities, and what can be to overcome this dangerous irony. 1 fig.

Renewable energy in Hawaii--Lessons learned  

SciTech Connect

Hawaii`s extensive renewable resources and limited access to conventional fuels has, in a sense, created a natural environment for the development and implementation of renewable energy processes, technologies, and materials. Aside from its traditional combustion of bagasse at sugar mills, Hawaii has invested in a wide range of renewable energy technologies, including municipal waste-to-energy incineration, hydropower, wind energy, solar photovoltaic (PV), small-scale solar, geothermal, and innovative hybrid wind/diesel and wind/pumped hydro systems. While regarded as a leader in the field of renewable energy, Hawaii`s pioneering approach has generally focused on research and development rather on implementation and commercialization. Despite being a front-runner in the utilization of a number of renewable energy resources, Hawaii`s dependence on petroleum continues to be among the highest in the United States. In 1990, petroleum constituted 92% of Hawaii`s energy supply in contrast to renewable energy`s contribution of 8%. The introduction of coal-fired electricity generation in 1992 has helped to diversify the energy base and decrease the share of oil. But, coal`s low fuel costs may also impact negatively on the prospects for renewable energy. The combination of the impending decline of sugarcane and the growing concerns for the islands` energy and environmental security is changing Hawaii`s energy landscape. While a number of traditional options may be phased out over the next few years, the emergence of new prospects holds considerable promise for an expanded role for renewable energy in the future.

International Voluntary Renewable Energy Markets (Presentation)  

SciTech Connect

This presentation provides an overview of international voluntary renewable energy markets, with a focus on the United States and Europe. The voluntary renewable energy market is the market in which consumers and institutions purchase renewable energy to match their electricity needs on a voluntary basis. In 2010, the U.S. voluntary market was estimated at 35 terawatt-hours (TWh) compared to 300 TWh in the European market, though key differences exist. On a customer basis, Australia has historically had the largest number of customers, pricing for voluntary certificates remains low, at less than $1 megawatt-hour, though prices depend on technology.

State Clean Energy Practices: Renewable Fuel Standards  

SciTech Connect

The State Clean Energy Policies Analysis (SCEPA) project is supported by the Weatherization and Intergovernmental Program within the Department of Energy's Office of Energy Efficiency and Renewable Energy. This project seeks to quantify the impacts of existing state policies, and to identify crucial policy attributes and their potential applicability to other states. The goal is to assist states in determining which clean energy policies or policy portfolios will best accomplish their environmental, economic, and security goals. For example, renewable fuel standards (RFS) policies are a mechanism for developing a market for renewable fuels in the transportation sector. This flexible market-based policy, when properly executed, can correct for market failures and promote growth of the renewable fuels industry better than a more command-oriented approach. The policy attempts to correct market failures such as embedded fossil fuel infrastructure and culture, risk associated with developing renewable fuels, consumer information gaps, and lack of quantification of the non-economic costs and benefits of both renewable and fossil-based fuels. This report focuses on renewable fuel standards policies, which are being analyzed as part of this project.

An Economic Evaluation Framework for Assessing Renewable Energy Projects  

SciTech Connect

It is becoming increasingly imperative to integrate renewable energy, such as solar and wind, into electricity generation due to increased regulations on air and water pollution and a sociopolitical desire to develop more clean energy sources. This increased spotlight on renewable energy requires evaluating competing projects using either conventional economic analysis techniques or other economics-based models and approaches in order to select a subset of the projects to be funded. Even then, there are reasons to suspect that techniques applied to renewable energy projects may result in decisions that will reject viable projects due to the use of a limited number of quantifiable and tangible attributes about the projects. This paper presents a framework for economic evaluation of renewable energy projects. The framework is based on a systems approach in which the processes within the entire network of the system, from generation to consumption, are accounted for. Furthermore, the framework uses the concept of fuzzy system to calculate the value of information under conditions of uncertainty.

Factors that promote renewable energy production in U.S. states: A fixed effect estimation  

NASA Astrophysics Data System (ADS)

The unsustainability of conventional energy sources and its environmental destructions are well-known; the sustainability of renewable energy and its environmental benefits are also well-documented. The United States in common with many other countries is increasingly focused on developing renewable energy. At first, the pursuit of this strategy in U.S. was seen more as a way to reduce dependence on oil importation. With increased awareness of environmental challenges resulting from the consumption and production of conventional energy, an additional strategy for the continued interest in renewable energy development in the United States was as a result of its potential to ameliorate environmental problems. The U.S. government are utilizing policy measures and dedicating funding to encourage the development of renewable energy technologies. Beside government policies, there are contextual factors that also affect renewable energy production. These include, but not limited to population growth, energy demand, economic growth, and public acceptance. Given the pressing need to develop a sustainable energy, this study embarks on an outcome assessment of the nature of relationship of renewable energy policy incentives, and selected contextual factors on renewable energy production in the United States. The policy incentive evaluated in this study is the Renewable Energy Production Incentive program. The contextual factors evaluated in this study are energy consumption, population growth, employment, and poverty. Understanding the contextual factors within which policies are placed is essential to defining the most appropriate policy features. The methodological approach to the study is quantitative, using panel data from 1976 to 2007. The study tested two hypotheses using fixed effect estimation with robust standard error as a statistical model. Statistical analyses reveal several interesting results which lend support that besides policy incentives, contextual factors also affect renewable energy production. It therefore appears that to obtain a maximum renewable energy production, policymakers need to adopt a policy approach that incorporates these contextual factors.

International cooperation for renewable energy transfer  

SciTech Connect

This paper reports that in considering the potential of major renewable energy resources in relation to their remoteness from demand centers, it is necessary to take a global view of the implications of their utilization. The present concerns regarding global warming and environmental degradation from fossil fuel combustion could be given active direction if the positive benefits of renewable energy could be realized on a meaningful scale. The dire prospect of global warming looms large in the scientific consciousness, but strategies to counter the effects of increased release of carbon dioxide and other greenhouse gases are just beginning to emerge along with remedial measures to address other environmental threats. One of the ways to achieve this is to place more reliance on renewable energy. As the impact of small-scale dispersed sources of renewable energy is minimal in comparison with fossil fuel usage, a meaningful impact could only be made by drawing upon major sources of renewable energy, mainly hydropower, tidal, and solar, in large capacity installations concentrated at sites relatively far from demand centers. There are sites that warrant serious consideration in the face of the growing environmental impact of fossil fuel usage. However, to realize this objective, an environmental imperative should be adopted that would place the importance of global environmental security on a par with present concerns for national security.

Findings are based on secondary energy consumption in the Federal Republic of Germany. Results show that potential energy savings can reduce demand for primary energy by 265 to 290 billion kilowatt hours. (8% to 9% of the total demand of the Federal Republic of Germany).

DRI Renewable Energy Center (REC) (NV)  

SciTech Connect

The primary objective of this project was to utilize a flexible, energy-efficient facility, called the DRI Renewable Energy Experimental Facility (REEF) to support various renewable energy research and development (R&D) efforts, along with education and outreach activities. The REEF itself consists of two separate buildings: (1) a 1200-ft2 off-grid capable house and (2) a 600-ft2 workshop/garage to support larger-scale experimental work. Numerous enhancements were made to DRI's existing renewable power generation systems, and several additional components were incorporated to support operation of the REEF House. The power demands of this house are satisfied by integrating and controlling PV arrays, solar thermal systems, wind turbines, an electrolyzer for renewable hydrogen production, a gaseous-fuel internal combustion engine/generator set, and other components. Cooling needs of the REEF House are satisfied by an absorption chiller, driven by solar thermal collectors. The REEF Workshop includes a unique, solar air collector system that is integrated into the roof structure. This system provides space heating inside the Workshop, as well as a hot water supply. The Workshop houses a custom-designed process development unit (PDU) that is used to convert woody biomass into a friable, hydrophobic char that has physical and chemical properties similar to low grade coal. Besides providing sufficient space for operation of this PDU, the REEF Workshop supplies hot water that is used in the biomass treatment process. The DRI-REEF serves as a working laboratory for evaluating and optimizing the performance of renewable energy components within an integrated, residential-like setting. The modular nature of the system allows for exploring alternative configurations and control strategies. This experimental test bed is also highly valuable as an education and outreach tool both in providing an infrastructure for student research projects, and in highlighting renewable energy features to the public.

How might renewable energy technologies fit in the food-water-energy nexus?  

NASA Astrophysics Data System (ADS)

Feeding the growing population in the U.S. will require additional land for crop and livestock production. Similarly, a growing population will require additional sources of energy. Renewable energy is likely to play an increased role in meeting the new demands of electricity consumers. Renewable energy technologies can differ from conventional technologies in their operation and their siting locations. Many renewable energy technologies have a lower energy density than conventional technologies and can also have large land use requirements. Much of the prime area suitable for renewable energy development in the U.S. has historically been used for agricultural production, and there is some concern that renewable energy installations could displace land currently producing food crops. In addition to requiring vast expanses of land, both agriculture and renewable energy can require water. The agriculture and energy sectors are responsible for the majority of water withdrawals in the U.S. Increases in both agricultural and energy demand can lead to increases in water demands, depending on crop management and energy technologies employed. Water is utilized in the energy industry primarily for power plant cooling, but it is also required for steam cycle processes and cleaning. Recent characterizations of water use by different energy and cooling system technologies demonstrate the choice of fuel and cooling system technologies can greatly impact the withdrawals and the consumptive use of water in the energy industry. While some renewable and conventional technology configurations can utilize more water per unit of land than irrigation-grown crops, other renewable technology configurations utilize no water during operations and could lead to reduced stress on water resources. Additionally, co-locating agriculture and renewable energy production is also possible with many renewable technologies, avoiding many concerns about reductions in domestic food production. Various metrics exist for defining land use impacts of energy technologies, with little consensus on how much total land is impacted or is necessary. Here we characterize the land use requirements of energy technologies by comparing various metrics from different studies, providing ranges of the potential land impact from alternative energy scenarios. Land use requirements for energy needs under these scenarios are compared with projected land use requirements for agriculture to support a growing population. The water implications of various energy and food scenarios are analyzed to provide insights into potential regional impacts or conflicts between sectors.

Status report on renewable energy in the States

As the concept of integrated resource planning has spread among states and utilities, a reexamination of the role of renewable energy sources in the utility resource mix is taking place. This report documents the findings of a study of state regulatory commissions undertaken to: (1) help assess the state of knowledge and awareness about renewable energy resources and technologies; (2) assess the impacts of state policies on renewable energy development; and (3) identify important information needs. The key findings from this effort are: Renewable energy development has occurred only slowly over the last decade, and a small number of states account for the bulk of development. The development that has occurred has been limited to non-utility entities. Directed state policies have been a key driver in renewable energy development. Those states not currently addressing renewables may need more data and information before they proceed with directed policies. Other important observations are: The cost of renewables is an overriding concern. Regulators distinguish between 'emerging' and 'established' renewable energy technologies. Specific data are lacking on state-level renewable energy development. Detailed renewable resource assessments have yet to be performed in many states. This report identifies renewable energy information needs of state regulators. However, a number of concerns are also identified that must be addressed before renewables will receive serious attention in many of those states with limited renewables experience. Finally, the report catalogs a wide variety of policies that have been utilized in the states to promote greater development of renewable energy.

Optimal Power Allocation for Renewable Energy Source  

E-print Network

Battery powered transmitters face energy constraint, replenishing their energy by a renewable energy source (like solar or wind power) can lead to longer lifetime. We consider here the problem of finding the optimal power allocation under random channel conditions for a wireless transmitter, such that rate of information transfer is maximized. Here a rechargeable battery, which is periodically charged by renewable source, is used to power the transmitter. All of above is formulated as a Markov Decision Process. Structural properties like the monotonicity of the optimal value and policy derived in this paper will be of vital importance in understanding the kind of algorithms and approximations needed in real-life scenarios. The effect of curse of dimensionality which is prevalent in Dynamic programming problems can thus be reduced. We show our results under the most general of assumptions.

Energy Consumption of Die Casting Operations  

SciTech Connect

Molten metal processing is inherently energy intensive and roughly 25% of the cost of die-cast products can be traced to some form of energy consumption [1]. The obvious major energy requirements are for melting and holding molten alloy in preparation for casting. The proper selection and maintenance of melting and holding equipment are clearly important factors in minimizing energy consumption in die-casting operations [2]. In addition to energy consumption, furnace selection also influences metal loss due to oxidation, metal quality, and maintenance requirements. Other important factors influencing energy consumption in a die-casting facility include geographic location, alloy(s) cast, starting form of alloy (solid or liquid), overall process flow, casting yield, scrap rate, cycle times, number of shifts per day, days of operation per month, type and size of die-casting form of alloy (solid or liquid), overall process flow, casting yield, scrap rate, cycle times, number of shifts per day, days of operation per month, type and size of die-casting machine, related equipment (robots, trim presses), and downstream processing (machining, plating, assembly, etc.). Each of these factors also may influence the casting quality and productivity of a die-casting enterprise. In a die-casting enterprise, decisions regarding these issues are made frequently and are based on a large number of factors. Therefore, it is not surprising that energy consumption can vary significantly from one die-casting enterprise to the next, and within a single enterprise as function of time.

Renewable Energy Positioning System: Energy Positioning: Control and Economics

GENI Project: The University of Washington and the University of Michigan are developing an integrated system to match well-positioned energy storage facilities with precise control technologies so the electric grid can more easily include energy from renewable power sources like wind and solar. Because renewable energy sources provide intermittent power, it is difficult for the grid to efficiently allocate those resources without developing solutions to store their energy for later use. The two universities are working with utilities, regulators, and the private sector to position renewable energy storage facilities in locations that optimize their ability to provide and transmit electricity where and when it is needed most. Expanding the network of transmission lines is prohibitively expensive, so combining well-placed storage facilities with robust control systems to efficiently route their power will save consumers money and enable the widespread use of safe, renewable sources of power.

There is growing interest in renewable energy around the world. Since most renewable sources are intermittent in nature, it is a challenging task to integrate renewable energy resources into the power grid infrastructure. In this grid integration, communication systems are crucial technologies, which enable the accommodation of distributed renewable energy generation and play extremely important role in monitoring, operating, and protecting both renewable energy generators and power systems. In this paper, we review some communication technologies available for grid integration of renewable energy resources. Then, we present the communication systems used in a real renewable energy project, Bear Mountain Wind Farm (BMW) in British Columbia, Canada. In addition, we present the communication systems used in Photovoltaic Power Systems (PPS). Finally, we outline some research challenges and possible solutions about the communication systems for grid integration of renewable energy resources.

The status of renewable energy technology  

NASA Astrophysics Data System (ADS)

Renewable energy technologies convert naturally occurring phenomena into useful energy forms. These technologies use resources that generally are not depleted, such as the direct energy (heat and light) from the sun and the indirect results of its impact on the earth (wind, falling water, heating effects, plant growth), gravitational forces (the tides), and the heat of the Earth's core (geothermal), as the sources from which they produce useful energy. These very large stores of natural energy represent a resource potential that is incredibly massive, and dwarfs that of equivalent fossil energy resources. The magnitude of these resources is, therefore, not a key constraint on energy production. However, they are generally diffuse and not fully accessible, some are intermittent, and all have distinct regional and local variability. It is these aspects of their character that give rise to difficult, but generally solvable, technical, institutional, and economic challenges inherent in development and use of renewable energy resources. This report discusses the technologies and their associated energy source.

This paper describes a method for determining the combination of renewable energy technologies that minimize life-cycle cost at a facility, often with a specified goal regarding percent of energy use from renewable sources. Technologies include: photovoltaics (PV); wind; solar thermal heat and electric; solar ventilation air preheating; solar water heating; biomass heat and electric (combustion, gasification, pyrolysis, anaerobic digestion); and daylighting. The method rests upon the National Renewable Energy Laboratory's (NREL's) capabilities in characterization of technology cost and performance, geographic information systems (GIS) resource assessment, and life-cycle cost analysis. The paper discusses how to account for the way candidate technologies interact with each other, and the solver routine used to determine the combination that minimizes life-cycle cost. Results include optimal sizes of each technology, initial cost, operating cost, and life-cycle cost, including incentives from utilities or governments. Results inform early planning to identify and prioritize projects at a site for subsequent engineering and economic feasibility study.

Renewable Energy Options for a Utility System  

NASA Astrophysics Data System (ADS)

In this paper, renewable energies have been re-addressed with respect to the potentials and feasibility of being incorporated in process industries. Within a process, utility system is considered to be the most appropriate place for using sustainable energies. For integrating the renewable energies, the pinch analysis is applied as the main tool to provide opportunity for energy conservation. The results demonstrated that the power generation by the wind is the most cost effective and environmentally friendly option for energy conservation in comparison to the other sustainable resources. However the tidal energy stands the least due to the long payback period. Also, a computer program has been developed, using MATLAB 7.3, to screen out different scenarios and perform economic study. The outcome data showed that, there are several different opportunities for the integration of alternative energies. Finally, this method has been applied to a case study and various retrofit projects have been identified, each of which has certain amount of CO2 reduction and estimated values for the required investment, saving potential and payback period.

WIRE: Weather Intelligence for Renewable Energies  

NASA Astrophysics Data System (ADS)

Renewable energies such as wind and solar energy will play an important, even decisive role in order to mitigate and adapt to the projected dramatic consequences to our society and environment due to climate change. Due to shrinking fossil resources, the transition to more and more renewable energy shares is unavoidable. But, as wind and solar energy are strongly dependent on highly variable weather processes, increased penetration rates will also lead to strong fluctuations in the electricity grid which need to be balanced. Proper and specific forecasting of ‘energy weather' is a key component for this. Therefore, it is today appropriate to scientifically address the requirements to provide the best possible specific weather information for forecasting the energy production of wind and solar power plants within the next minutes up to several days. Towards such aims, Weather Intelligence will first include developing dedicated post-processing algorithms coupled with weather prediction models and with past and/or online measurement data especially remote sensing observations. Second, it will contribute to investigate the difficult relationship between the highly intermittent weather dependent power production and concurrent capacities such as transport and distribution of this energy to the end users. Selecting, resp. developing surface-based and satellite remote sensing techniques well adapted to supply relevant information to the specific post-processing algorithms for solar and wind energy production short-term forecasts is a major task with big potential. It will lead to improved energy forecasts and help to increase the efficiency of the renewable energy productions while contributing to improve the management and presumably the design of the energy grids. The second goal will raise new challenges as this will require first from the energy producers and distributors definitions of the requested input data and new technologies dedicated to the management of power plants and electricity grids and second from the meteorological measurement community to deliver suitable, short term high quality forecasts to fulfill these requests with emphasis on highly variable weather conditions and spatially distributed energy productions often located in complex terrain. This topic has been submitted for a new COST Action under the title "Short-Term High Resolution Wind and Solar Energy Production Forecasts".

Integrating Renewable Energy Requirements Into Building Energy Codes  

SciTech Connect

This report evaluates how and when to best integrate renewable energy requirements into building energy codes. The basic goals were to: (1) provide a rough guide of where we’re going and how to get there; (2) identify key issues that need to be considered, including a discussion of various options with pros and cons, to help inform code deliberations; and (3) to help foster alignment among energy code-development organizations. The authors researched current approaches nationally and internationally, conducted a survey of key stakeholders to solicit input on various approaches, and evaluated the key issues related to integration of renewable energy requirements and various options to address those issues. The report concludes with recommendations and a plan to engage stakeholders. This report does not evaluate whether the use of renewable energy should be required on buildings; that question involves a political decision that is beyond the scope of this report.

Understanding energy consumption: Beyond technology and economics  

SciTech Connect

This paper summarizes two years of efforts among a cross-disciplinary group of senior researchers to bring social and cultural perspectives to modeling of household energy consumption. The work has been organized by the Center for Energy Studies of the University of Geneva. The researchers represent both the physical and social sciences, several institutions and a number of countries. The initiative was based on an acknowledgement of the failure of technical and economic models to explain consumption or more importantly, how consumption patterns change. Technical and economic models most often either ignore social and cultural issues or reduce them to parameters of other variables. An important objective for the Geneva Group has been to engage modelers and social scientists in a dialogue which brings social and cultural context to the fore. The process reveals interesting insights into the frictions of cross-disciplinary interaction and the emergence of new perspectives. Various classical modeling approaches have been discussed and rejected. Gradually, a framework has emerged which says something about the appropriate institutions and actors which contribute to consumption patterns; about how they are related; and finally about how the interinstitutional relationships and the consumption patterns themselves change. A key point of convergence is that a complete understanding of energy end-use will not be possible from an analysis directed at the point of end use alone. The analysis must incorporate what happens inside institutions like manufacturers, retailers, and public policy organizations as well as how those organizations interact with consumers, including media and advertising. Progress towards a better understanding of energy consumption requires a greater engagement of social scientists with these heretofore little explored actors an relationships.

However, IEUA is preparing a Supplemental report that will be mailed to the Department of Energy (DOE) by August 1, 2003, that provides additional information regarding IEUA's plan to expedite certain project activities. The report has been prepared in accordance with the Department of Energy (DOE) Guidelines. This technical report covers all meetings, discussions, and engineering and design activities that took place to finalize the project scope of work and complete the Request for Proposal (RFP) for the RP-5 Renewable Energy Efficiency Project. IEUA has decided to invite three more consulting engineering firms besides CH2M Hill, the Public Interest Energy Research (PIER) Consultant, to submit proposals for the design of the energy efficiency project. The proposals are currently in the evaluation phase and a decision is expected by the end of July. IEUA moved to its new headquarters building on June 13, 2003. The central plant is the system that supplies cooling and heating water to the headquarters building, and it primarily consists of equipment listed in the cooperative agreement under ''Chiller and Heater''. The central plant equipment was successfully installed and started. Other activities include gas analysis of three sources of low quality digester gas and foul air which could be used as fuel for an innovative flex microturbine. IEUA is also working with Stirling Energy Systems to determine if the Agency should be a host site for their equipment for testing the engine's operation on digester and natural gas. A matching funds update is also included in the Results and Discussion section, which presents the work effort performed by the PIER Consultant and the associated costs that serve as matching funds for the RP-5 Project during this report period.

Renewable energy and conservation measures for non-residential buildings  

NASA Astrophysics Data System (ADS)

The energy demand in most countries is growing at an alarming rate and identifying economically feasible building retrofit solutions to decrease the need for fossil fuels so as to mitigate their environmental and societal impacts has become imperative. Two approaches are available for identifying feasible retrofit solutions: 1) the implementation of energy conservation measures; and 2) the production of energy from renewable sources. This thesis focuses on the development of retrofit software planning tools for the implementation of solar photovoltaic systems, and lighting system retrofits for mid-Michigan institutional buildings. The solar planning tool exploits the existing blueprint of a building's rooftop, and via image processing, the layouts of the solar photovoltaic arrays are developed based on the building's geographical location and typical weather patterns. The resulting energy generation of a PV system is estimated and is utilized to determine levelized energy costs. The lighting system retrofit analysis starts by a current utilization assessment of a building to determine the amount of energy used by the lighting system. Several LED lighting options are evaluated on the basis of color correlation temperature, color rendering index, energy consumption, and financial feasibility, to determine a retrofit solution. Solar photovoltaic installations in mid-Michigan are not yet financially feasible, but with the anticipated growth and dynamic complexity of the solar photovoltaic market, this solar planning tool is able to assist building proprietors make executive decisions regarding their energy usage. Additionally, a lighting system retrofit is shown to have significant financial and health benefits.

NASA Astrophysics Data System (ADS)

The demand for renewable energy in social energy systems has grown in recent years. In the atmospheric sciences, the energy balances and dynamics in the atmosphere are studied on both local and global scales, and thus estimation of renewable energy is an important practical application. For instance, shortwave solar radiation that reaches Earth's surface is an essential quantity for evaluating the photovoltaic (PV) power generation. Indeed, shortwave solar radiation can be calculated by a radiative transfer solver and an accurate electromagnetic wave scattering theory. A beneficial application of atmospheric sciences is obtaining of solar radiation on the basis of geostationary satellite measurements. Such satellites provide data covering most parts of the Earth every 30 min to 1 h. Geo-parameters such as cloud and aerosol properties are needed for calculating the amount of solar radiation that reaches Earth's surface. Multispectral images acquired by geostationary satellites allow for such geo-parameters to be evaluated. Additionally, polar-orbiting Earth observation satellites are also needed for improving data analysis techniques. For instance, multispectral imagers (e.g., MODIS) and cloud radars (e.g., CloudSat) aboard polar-orbiting satellites can be used to reveal the relationship between multispectral imaging results and the vertical structure of clouds. The EarthCARE (JAXA, ESA, NICT) and the GCOM-C (JAXA) satellites that will be launched in the middle of 2010-era are also used for improving cloud and aerosol process. This paper presents a method using satellite data to evaluate the optical and microphysical parameters of clouds that affect solar radiation. Also presented is a method for evaluating solar radiation that reaches Earth's surface. A new research project in Japan, JST-CREST-EMS (Energy Management System)-TEEDDA (Terrestrial Energy Estimation by Diurnal Data Analyses), which was started in October 2012, is also introduced.

[Analysis of China's energy consumption and its impact on the environment in the future].  

PubMed

With the development of economy and urbanization, energy consumption and its impact on the environment in the future have become a focal point in China. Based on briefly reviewing energy consumption during 1980-2000 and analyzing its impact, three scenarios are assumed to forecast energy consumption status and analyze its impact on the environment in the future. The results indicate that the emissions of SO2, NOx, CO2 and soot dust caused by energy consumption would keep a high level in the future, and there are significant differences among the three scenarios' estimates. Improving energy efficiency and strengthening the exploitation and utilization of clean and renewable energy are suggested to mitigate the environmental pollution. PMID:16124459

Nuclear and Renewable Energy Synergies Workshop: Report of Proceedings  

SciTech Connect

Two of the major challenges the U.S. energy sector faces are greenhouse gas emissions and oil that is both imported and potentially reaching a peak (the point at which maximum extraction is reached). Interest in development of both renewable and nuclear energy has been strong because both have potential for overcoming these challenges. Research in both energy sources is ongoing, but relatively little research has focused on the potential benefits of combining nuclear and renewable energy. In September 2011, the Joint Institute for Strategic Energy Analysis (JISEA) convened the Nuclear and Renewable Energy Synergies Workshop at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) to identify potential synergies and strategic leveraging opportunities between nuclear energy and renewable energy. Industry, government, and academic thought leaders gathered to identify potential broad categories of synergies and brainstorm topic areas for additional analysis and research and development (R&D). This report records the proceedings and outcomes of the workshop.

This is the final technical report for the RP-5 Renewable Energy Efficiency Project (REEP). The report summarizes, in a comprehensive manner, all the work performed during the award period extending between July 12, 2002 and June 30, 2007. This report has been prepared in accordance with the Department of Energy (DOE) Guidelines and summarizes all of the activities that occurred during the award period. The RP-5 Renewable Energy Efficiency Project, under development by the Inland Empire Utilities Agency (IEUA), is comprised of a series of full-scale demonstration projects that will showcase innovative combinations of primary and secondary generation systems using methane gas derived from local processing of biosolids, dairy manure and other organic material. The goal of the project is to create renewable energy-based generation systems with energy efficiencies 65% or more. The project was constructed at the 15 MGD Regional Wastewater Treatment Plant No. 5 located in the City of Chino in California where the Agency has constructed its new energy-efficient (platinum-LEED rating) headquarters building. Technologies that were featured in the project include internal combustion engines (ICE), absorption chillers, treatment plant secondary effluent cooling systems, heat recovery systems, thermal energy storage (TES), Organic Rankine Cycle (ORC) secondary power generation system, the integration of a future fuel cell system, gas cleaning requirements, and other state-of-the-art design combinations. The RP-5 REEP biogas source is coming from three manure digesters which are located within the RP-5 Complex and are joined with the RP-5 REEP through gas conveyance pipelines. Food waste is being injected into the manure digesters for digester gas production enhancement. The RP-5 REEP clearly demonstrates the biogas production and power generation viability, specifically when dealing with renewable and variable heating value (Btu) fuel. The RP-5 REEP was challenged with meeting stringent utility, gas, power, and air quality rules and regulations. Coordination with the Southern California Gas Company (SCGC), Southern California Edison (SCE), and South Coast Air Quality Management District (SCAQMD) was continuous and extensive. The interconnecting agreement and the permit to construct and operate were major obstacles despite the early start and coordination with the utility companies and regulatory agencies. The RP-5 REEP is part of a unique RP-5 Complex approach where several facilities are tied and connected with each other; where energy and gas can be transferred from one facility to another (see attached RP-5 Complex Ultimate Energy Balance Diagram). The REEP also incorporated new technologies, such as TES and ORC, along with using heat recovery for the platinum-LEED headquarter buildings heating and cooling via efficient absorption chillers. Through the conceptual design phase, numerous innovative technologies were researched and evaluated, with the most proven and efficient selected to be part of the RP-5 REEP.

Assessing the Energy Consumption of Smartphone Applications  

NASA Astrophysics Data System (ADS)

Mobile devices are increasingly becoming essential in people's lives. The advancement in technology and mobility factor are allowing users to utilize mobile devices for communication, entertainment, financial planning, fitness tracking, etc. As a result, mobile applications are also becoming important factors contributing to user utility. However, battery capacity is the limiting factor impacting the quality of user experience. Hence, it is imperative to understand how much energy impact do mobile apps have on the system relative to other device activities. This thesis presents a systematic studying of the energy impact of mobile apps features. Time-series electrical current measurements are collected from 4 different modern smartphones. Statistical analysis methodologies are used to calculate the energy impact of each app feature by identifying and extracting mobile app-feature events from the overall current signal. In addition, the app overhead energy costs are also computed. Total energy consumption equations for each component is developed and an overall total energy consumption equation is presented. Minutes Lost (ML) of normal phone operations due to the energy consumption of the mobile app functionality is computed for cases where the mobile app is simulated to run on the various devices for 30 minutes. Tutela Technologies Inc. mobile app, NAT, is used for this study. NAT has two main features: QoS and Throughput. The impact of the QoS feature is indistinguishable, i.e. ML is zero, relative to other phone activities. The ML with only the TP feature enabled is on average 2.1 minutes. Enabling the GPS increases the ML on average to 11.5 minutes. Displaying the app GUI interface in addition to running the app features and enabling the GPS results in an average ML of 12.4 minutes. Amongst the various mobile app features and components studied, the GPS consumes the highest amount of energy. It is estimated that the GPS increases the ML by about 448%.

Public opinion and communicative action around renewable energy projects  

NASA Astrophysics Data System (ADS)

This thesis investigates how rural communities negotiate the development of renewable energy projects. Public and local community acceptance of these new technologies in rural areas around the world is uncertain and spatially uneven and represents an area of emerging public policy interest and one where scholarly theory is rapidly developing. This thesis uses Habermasian concepts of public sphere, communicative action and deliberative democracy, as well as the concept of "wicked problems" from the planning studies literature combined with geographical concepts of place and scale to advance theoretical and empirical understanding of how public opinion on renewable energy technologies is formed in place. It documents energy use patterns, attitudes and socio-political relations at a time when considerable state and business efforts are directed at the construction of solar, wind, biomass and small-hydro technologies in rural regions. These concepts and theories are applied in a case study of rural communities in the Eastern Ontario Highlands, an impoverished area undergoing rapid restructuring driven by centralization of services and amenity migration but with abundant natural resources in form of forests, numerous waterways and open space which have attracted a broad range of new energy developments. Overall high levels of support for alternative energy development particularly for solar power were found, albeit for reasons of local energy security and not for reasons of preventing climate change. There was some evidence that seasonal residents are less supportive of hydro and biomass projects than permanent residents possibly reflecting broader trends in rural economies away from productive uses of land to consumptive appreciation of rural landscapes. The thesis suggests that collective action to advance energy projects in the case study area require agreement along three world-claims (truth, rightness and truthfulness) and that communication leading to discourse which uncovers hitherto hidden reasons for action is possible. These findings offer rare empirical evidence of the predictions of deliberative democratic theory in environmental planning settings. However, multiple barriers to communicative action were also identified and there is evidence that the state's reliance on market incentives may have long term costs in terms of diminished public reasoning around renewable energy.

Renewable energy: Energy from agricultural products  

NASA Astrophysics Data System (ADS)

Agricultural products, particularly sugarcane and corn, are currently meeting major energy needs in Florida. Recent figures indicate that about 10 percent of the gasoline sold in Florida is ethanol enriched. This gasohol contains a 10 percent mix of ethanol, which is generally produced from corn or sugarcane molasses. Sugarcane residues (bagasse) also supply most of the fuel to power Florida's large sugar processing industry. These products have the potential to play an expanded role in Florida's energy future. Neither ethanol nor methane appear able to compete in the free market for mass distribution at present, although studies indicate that genetic engineering and more efficient conversion processes may lower prices to cost effective levels. These fuels will be most cost effective in cases where waste products are utilized and the fuel is used close to the site of production. Wider applications will require either government incentives or genetic engineering of crops and improve efficiencies in conversion processes to lower costs.

Renewable energy: energy from agricultural products

This report discusses the major issues concerning fuels derived from agricultural products. Agricultural products, particularly sugarcane and corn, are currently meeting major energy needs in Florida. Recent figures indicate that about 10 percent of the gasoline sold in Florida is ethanol enriched. This gasohol contains a 10 percent mix of ethanol, which is generally produced from corn or sugarcane molasses. Sugarcane residues (bagasse) also supply most of the fuel to power Florida's large sugar processing industry. These products have the potential to play an expanded role in Florida's energy future. Principle areas of interest are: growing crops such as napier grass or harvesting water hyacinths to produce methane that can be substituted for natural gas; expanded use of sugar, starch, and industrial and agricultural wastes as raw materials for ethanol production; and improved efficiency in conversion processes such as anaerobic digestion and fermentation. The Institute of Food and Agricultural Sciences at the University of Florida plays a leading national role in energy crops research, while Walt Disney World is using a demonstration project to convert water hyacinths into methane. Increased use of fuels produced from agricultural products depends largely on their costs compared to other fuels. Ethanol is currently attractive because of federal and state tax incentives. The growth potential of ethanol and methane is enhanced by the ease with which they can be blended with fossil fuels and thereby utilize the current energy distribution system. Neither ethanol nor methane appear able to compete in the free market for mass distribution at present, although studies indicate that genetic engineering and more efficient conversion processes may lower prices to cost effective levels.

Role of Renewable Energy Certificates in Developing New Renewable Energy Projects  

SciTech Connect

For more than a decade, renewable energy certificates (RECs) have grown in use, becoming a common way to track ownership of the renewable and environmental attributes of renewable electricity generation. In recent years, however, questions have risen about the role RECs play in the decision to build new renewable energy projects. Information from a variety of market participants suggests that the importance of RECs in building new projects varies depending on a number of factors, including electricity market prices, the cost-competitiveness of the project, the presence or absence of public policies supportive of new projects, contract duration, and the perspective of different market participants. While there is no single answer to the role that RECs play, there are situations in which REC revenues are essential to project economics, as well as some where REC revenues may have little impact. To strengthen the role RECs play in both compliance and voluntary markets, there are a number of options that could be considered. In compliance markets, lawmakers or regulators would have to adopt measures that strengthen the role of RECs in the development of new projects, while in voluntary markets, it would be up to program leaders and market participants themselves to implement measures.

Mining landforms - A renewable energy development opportunity  

SciTech Connect

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. The terrace-landform development of mineral properties in remote, infrastructurally destitute areas creates renewable energy, sustainable, electric power-water {open_quotes}oases.{close_quotes} The landform development of mineral properties adjacent to metropolitan areas creates utilities expansions and recreational {open_quotes}greenspace{close_quotes} in areas of growing urban need.

Carbon dioxide, the feedstock for using renewable energy  

NASA Astrophysics Data System (ADS)

Extrapolation of world energy consumption between 1990 and 2007 to the future reveals the complete exhaustion of petroleum, natural gas, uranium and coal reserves on Earth in 2040, 2044, 2049 and 2054, respectively. We are proposing global carbon dioxide recycling to use renewable energy so that all people in the whole world can survive. The electricity will be generated by solar cell in deserts and used to produce hydrogen by seawater electrolysis at t nearby desert coasts. Hydrogen, for which no infrastructures of transportation and combustion exist, will be converted to methane at desert coasts by the reaction with carbon dioxide captured by energy consumers. Among systems in global carbon dioxide recycling, seawater electrolysis and carbon dioxide methanation have not been performed industrially. We created energy-saving cathodes for hydrogen production and anodes for oxygen evolution without chlorine formation in seawater electrolysis, and ideal catalysts for methane formation by the reaction of carbon dioxide with hydrogen. Prototype plant and industrial scale pilot plant have been built.

Renewable energy technologies and its adaptation in an urban environment  

NASA Astrophysics Data System (ADS)

This general article is based on the inaugural talk delivered at the opening of OMTAT 2013 conference. It notes that the integration of renewable energy sources into living and transport sectors presents a daunting task, still. In spite of the fact that the earth and its atmosphere continually receive 1.7 × 1017 watts of radiation from the sun, in the portfolio of sustainable and environment friendly energy options, which is about 16% of the world's energy consumption and mostly met by biomass, only a paltry 0.04% is accredited to solar. First and second generation solar cells offer mature technologies for applications. The most important difficulty with regards to integration with structures is not only the additional cost, but also the lack of sufficient knowledge in managing the available energy smartly and efficiently. The incorporation of PV as a part of building fabric greatly reduces the overall costs compared with retrofitting. BIPV (Building Integrated photovoltaic) is a critical technology for establishing aesthetically pleasing solar structures. Infusing PV and building elements is greatly simplified with some of the second generation thin film technologies now manufactured as flexible panels. The same holds true for 3rd generation technologies under development such as, and dye- and quantum dot- sensitized solar cells. Additionally, these technologies offer transparent or translucent solar cells for incorporation into windows and skylights. This review deals with the present state of solar cell technologies suitable for BIPV and the status of BIPV applications and its future prospects.

Matching renewable energy systems to village-level energy needs  

SciTech Connect

This report provides a five step process for matching alternative renewable energy technologies with energy needs in rural villages of developing countries. Analytic tools are given for each of the five steps as well as information that can be expected. Twelve characterization criteria are developed to assist in the matching process. Three of these criteria, called discrimination criteria, are used for preliminary screening of technology possibilities for each need. The other criteria address site-specific temporal, climatic, social, cultural, and environmental characteristics of the energy need, technology, and cost considerations. To illustrate the matching process, seven basic human needs for energy are matched with seven potential renewable energy technologies. The final portion of the paper discusses the advantages of such a matching process and the resources required to initiate such an effort within a development project. Specific recommendations are given for field-testing this process and actions that could be taken immediately in basic research and development, applied research and technology modification, demonstrations, and commercialization to assist in the future diffusion of renewable energy technologies to rural areas of developing countries.

Development of Electricity Generation from Renewable Energy Sources in Turkey  

NASA Astrophysics Data System (ADS)

Electricity is mainly produced from coal, natural gas and hydropower in Turkey. However, almost all the natural gas and high quality coal are imported. Thus, increasing the shares of both hydro and other renewables in energy supply is necessary to decrease dependency of the country on foreign sources. In 2008, the total installed capacity of Turkey was around 42000 MW and 66 % of this was from thermal sources. The remaining 33 % was from hydro, which leaves only one percent for the other renewable energy sources. The share of renewable energy in the energy budget of Turkey has increased in the last two decades; however, in 2008, only 17 % of the total electricity generation was realized from renewable sources most of which was hydro. According to State Hydraulic Works (SHW) which is the primary executive state agency responsible for the planning, operating and managing of Turkey's water resources, Turkey utilizes only around 35% of its economically viable hydro potential. The current situation clearly demonstrates the need for increasing the share of renewables in the energy budget. New laws, such as the Electricity Market Law, have been enacted and the following items were identified by the Ministry of Energy and Natural Resources of Turkey among primary energy policies and priorities: (i) decreasing dependency on foreign resources by prioritizing utilization of natural resources, (ii) increasing the share of renewable energy resources in the energy budget of Turkey; (iii) minimization of adverse environmental impacts of production and utilization of natural resources. The government's energy policy increased investments in renewable energy resources; however lack of a needed legal framework brought various environmental and social problems with this fast development. The development of the share of renewable resources in the energy budget, current government policy, and environmental concerns related with renewables, and ideas to improve the overall benefits of the use of these domestic energy sources are investigated in this study.

Renewable energy recovery through selected industrial wastes  

NASA Astrophysics Data System (ADS)

Typically, industrial waste treatment costs a large amount of capital, and creates environmental concerns as well. A sound alternative for treating these industrial wastes is anaerobic digestion. This technique reduces environmental pollution, and recovers renewable energy from the organic fraction of those selected industrial wastes, mostly in the form of biogas (methane). By applying anaerobic technique, selected industrial wastes could be converted from cash negative materials into economic energy feed stocks. In this study, three kinds of industrial wastes (paper mill wastes, brown grease, and corn-ethanol thin stillage) were selected, their performance in the anaerobic digestion system was studied and their applicability was investigated as well. A pilot-scale system, including anaerobic section (homogenization, pre-digestion, and anaerobic digestion) and aerobic section (activated sludge) was applied to the selected waste streams. The investigation of selected waste streams was in a gradually progressive order. For paper mill effluents, since those effluents contain a large amount of recalcitrant or toxic compounds, the anaerobic-aerobic system was used to check its treatability, including organic removal efficiency, substrate utilization rate, and methane yield. The results showed the selected effluents were anaerobically treatable. For brown grease, as it is already well known as a treatable substrate, a high rate anaerobic digester were applied to check the economic effect of this substrate, including methane yield and substrate utilization rate. These data from pilot-scale experiment have the potential to be applied to full-scale plant. For thin stillage, anaerobic digestion system has been incorporated to the traditional ethanol making process as a gate-to-gate process. The performance of anaerobic digester was applied to the gate-to-gate life-cycle analysis to estimate the energy saving and industrial cost saving in a typical ethanol plant.

Advanced Energy Efficiency and Distributed Renewables  

NASA Astrophysics Data System (ADS)

The US now wrings twice the GDP from each unit of energy that it did in 1975. Reduced energy intensity since then now provides more than twice as much service as burning oil does. Yet still more efficient end-use of energy -- explained more fully in a companion workshop offered at 1245 -- is the largest, fastest, cheapest, most benign, least understood, and least harnessed energy resource available. For example, existing technologies could save half of 2000 US oil and gas and three-fourths of US electricity, at lower cost than producing and delivering that energy from existing facilities. Saving half the oil through efficiency and replacing the other half with saved natural gas and advanced biofuels would cost an average of only 15/barrel and could eliminate US oil use by the 2040s, led by business for profit. Efficiency techniques and ways to combine and apply them continue to improve faster than they're applied, so the ``efficiency resource'' is becoming ever larger and cheaper. As for electricity, ``micropower'' (distributed renewables plus low-carbon cogeneration) is growing so quickly that by 2005 it provided a sixth of the world's electricity and a third of its new electricity, and was adding annually 4x the capacity and 11x the capacity added by nuclear power, which it surpassed in capacity in 2002 and in output in 2006. Together, micropower and ``negawatts'' (saved electricity) now provide upwards half the world's new electrical services, due to their far lower cost and lower financial risk than the central thermal power stations that still dominate policy discussions. For oil and electricity, each of which adds about two-fifths of the world's energy-related carbon dioxide emissions, efficiency plus competitive alternative supplies can stabilize the earth's climate at a profit, as well as solving the oil and (largely) the nuclear proliferation problems. Conversely, costlier and slower options, notably nuclear power, would displace less carbon emission per dollar and per year, thus worsening climate change compared with best-buys-first investments.

Energy consumption of personal computer workstations  

SciTech Connect

A field study directly measured the electric demand of 189 personal computer workstations for 1-week intervals, and a survey recorded the connected equipment at 1,846 workstations in six buildings. Each separate workstation component (e.g., computer, monitor, printer, modem, and other peripheral) was individually monitored to obtain detailed electric demand profiles. Other analyses included comparison of nameplate power rating with measured power consumption and the energy savings potential and cost-effectiveness of a controller that automatically turns off computer workstation equipment during inactivity. An important outcome of the work is the development of a standard workstation demand profile and a technique for estimating a whole-building demand profile. Together, these provide a method for transferring this information to utility energy analysts, design engineers, building energy modelers, and others. A life-cycle cost analysis was used to determine the cost-effectiveness of three energy conservation measures: (1) energy awareness education, (2) retrofit power controller installation, and (3) purchase of energy-efficient PCs.

Quinault Indian Nation Renewable Energy Plan  

SciTech Connect

The Quinault Indian Nation (Nation) initiated this study on conservation and production of renewable energy because this approach created the opportunity: • To become self-sufficient and gain greater control over the energy the Nation uses; • To generate jobs and businesses for its members; • To better manage, sustain, and protect its resources; • To express the cultural values of the Nation in an important new arena. The Nation has relatively small energy needs. These needs are concentrated at two separate points: the Quinault Beach Resort and Casino (QBRC) and Taholah on the Quinault Indian Reservation (QIR). Except for the town of Queets, energy needs are small and scattered. The needs vary greatly over the season. The small scale, widely dispersed, and variable nature of these needs presents a unique challenge to the Nation. Meeting these needs requires a resource and technology that is flexible, effective, and portable. Conservation is the most cost-effective way to meet any need. It is especially effective in a situation like this where production would leave a high per unit cost. This plan is based on first gaining energy savings through conservation. Major savings are possible through: 1. Upgrading home appliances on the QIR. 2. Weatherizing homes and facilities. 3. Changes in lighting/ventilation in the QBRC pool room. These elements of the plan are already being implemented and promise to save the Nation around a quarter of its present costs. Wood biomass is the best resource available to the QIN for energy production either on-site or for commercial development. It is abundant, flexible and portable. Its harvesting has high job potential and these jobs are a good fit for the present “skill set” of the QIN. This plan focuses on using wood biomass to produce energy and other value-added products. Our study considered various technologies and approaches to using wood for energy. We considered production for both on-site and commercial production. This plan calls for commercial-scale production only, with the QIN being the first “customer” for the product. This plan favors employing the pyrolysis technology to produce bio-oil, heat, and char. We favor this approach and technology because it is the most cost effective way to use the available resource. Its main product, bio-oil, has proven utility for the production of heat and electricity. It has promise for use as an alternative fuel, which is a much higher value than present uses of wood and it meets the QIN need for flexibility, scalability, and portability. Char, the secondary product from the pyrolysis process, has proven value-added uses. In addition to these direct benefits, the use of biomass in pyrolysis technology has significant indirect benefits. These benefits include the fact that the technology is a good fit with the Nation’s cultural values, i.e., environmental protection and the holistic use of a resource. It fits well with current QIN enterprises. For example, char could be processed into a charcoal co-product for QIN fish. Finally, the QIN can become a leader in developing and demonstrating this innovative approach to the use of wood. This plan proposes key organization steps to insure both excellent implementation of the plan and taking the best advantage of the processes and facilities put in place. This plan calls for two new QIN organizations: an energy production/distribution corporation and a community development corporation. The production/distribution corporation can be either a utility or a business enterprise that develops and markets renewable energy. The community development corporation can be a not-for-profit to support the QIN in taking best advantage of its energy opportunities. The production and distribution corporation is the subject of a further business planning effort now underway. This plan envisions a community development corporation that works directly with the Business Committee on research, education, and project development. Specifically, this corporation can seek grant funding to research energy m

Renewability and sustainability aspects of nuclear energy  

NASA Astrophysics Data System (ADS)

Renewability and sustainability aspects of nuclear energy have been presented on the basis of two different technologies: (1) Conventional nuclear technology; CANDU reactors. (2) Emerging nuclear technology; fusion/fission (hybrid) reactors. Reactor grade (RG) plutonium, 233U fuels and heavy water moderator have given a good combination with respect to neutron economy so that mixed fuel made of (ThO2/RG-PuO2) or (ThC/RG-PuC) has lead to very high burn up grades. Five different mixed fuel have been selected for CANDU reactors composed of 4 % RG-PuO2 + 96 % ThO2; 6 % RG-PuO2 + 94 % ThO2; 10 % RG-PuO2 + 90 % ThO2; 20 % RG-PuO2 + 80 % ThO2; 30 % RG-PuO2 + 70 % ThO2, uniformly taken in each fuel rod in a fuel channel. Corresponding operation lifetimes have been found as ˜ 0.65, 1.1, 1.9, 3.5, and 4.8 years and with burn ups of ˜ 30 000, 60 000, 100 000, 200 000 and 290 000 MW.d/ton, respectively. Increase of RG-PuO2 fraction in radial direction for the purpose of power flattening in the CANDU fuel bundle has driven the burn up grade to 580 000 MW.d/ton level. A laser fusion driver power of 500 MWth has been investigated to burn the minor actinides (MA) out of the nuclear waste of LWRs. MA have been homogenously dispersed as carbide fuel in form of TRISO particles with volume fractions of 0, 2, 3, 4 and 5 % in the Flibe coolant zone in the blanket surrounding the fusion chamber. Tritium breeding for a continuous operation of the fusion reactor is calculated as TBR = 1.134, 1.286, 1.387, 1.52 and 1.67, respectively. Fission reactions in the MA fuel under high energetic fusion neutrons have lead to the multiplication of the fusion energy by a factor of M = 3.3, 4.6, 6.15 and 8.1 with 2, 3, 4 and 5 % TRISO volume fraction at start up, respectively. Alternatively with thorium, the same fusion driver would produce ˜160 kg 233U per year in addition to fission energy production in situ, multiplying the fusion energy by a factor of ˜1.3.

Epibenthic Assessment of a Renewable Tidal Energy Site  

PubMed Central

Concern over global climate change as a result of fossil fuel use has resulted in energy production from renewable sources. Marine renewable energy devices provide clean electricity but can also cause physical disturbance to the local environment. There is a considerable paucity of ecological data at potential marine renewable energy sites that is needed to assess potential future impacts and allow optimal siting of devices. Here, we provide a baseline benthic survey for the Big Russel in Guernsey, UK, a potential site for tidal energy development. To assess the suitability of proposed sites for marine renewable energy in the Big Russel and to identify potential control sites, we compared species assemblages and habitat types. This baseline survey can be used to select control habitats to compare and monitor the benthic communities after installation of the device and contribute towards the optimal siting of any future installation.

RECENT TRENDS IN EMERGING TRANSPORTATION FUELS AND ENERGY CONSUMPTION  

SciTech Connect

Abundance of energy can be improved both by developing new sources of fuel and by improving efficiency of energy utilization, although we really need to pursue both paths to improve energy accessibility in the future. Currently, 2.7 billion people or 38% of the world s population do not have access to modern cooking fuel and depend on wood or dung and 1.4 billion people or 20% do not have access to electricity. It is estimated that correcting these deficiencies will require an investment of $36 billion dollars annually through 2030. In growing economies, energy use and economic growth are strongly linked, but energy use generally grows at a lower rate due to increased access to modern fuels and adaptation of modern, more efficient technology. Reducing environmental impacts of increased energy consumption such as global warming or regional emissions will require improved technology, renewable fuels, and CO2 reuse or sequestration. The increase in energy utilization will probably result in increased transportation fuel diversity as fuels are shaped by availability of local resources, world trade, and governmental, environmental, and economic policies. The purpose of this paper is to outline some of the recently emerging trends, but not to suggest winners. This paper will focus on liquid transportation fuels, which provide the highest energy density and best match with existing vehicles and infrastructure. Data is taken from a variety of US, European, and other sources without an attempt to normalize or combine the various data sources. Liquid transportation fuels can be derived from conventional hydrocarbon resources (crude oil), unconventional hydrocarbon resources (oil sands or oil shale), and biological feedstocks through a variety of biochemical or thermo chemical processes, or by converting natural gas or coal to liquids.

The impacts of renewable energy policies on renewable energy sources for electricity generating capacity  

NASA Astrophysics Data System (ADS)

Electricity generation from non-hydro renewable sources has increased rapidly in the last decade. For example, Renewable Energy Sources for Electricity (RES-E) generating capacity in the U.S. almost doubled for the last three year from 2009 to 2012. Multiple papers point out that RES-E policies implemented by state governments play a crucial role in increasing RES-E generation or capacity. This study examines the effects of state RES-E policies on state RES-E generating capacity, using a fixed effects model. The research employs panel data from the 50 states and the District of Columbia, for the period 1990 to 2011, and uses a two-stage approach to control endogeneity embedded in the policies adopted by state governments, and a Prais-Winsten estimator to fix any autocorrelation in the panel data. The analysis finds that Renewable Portfolio Standards (RPS) and Net-metering are significantly and positively associated with RES-E generating capacity, but neither Public Benefit Funds nor the Mandatory Green Power Option has a statistically significant relation to RES-E generating capacity. Results of the two-stage model are quite different from models which do not employ predicted policy variables. Analysis using non-predicted variables finds that RPS and Net-metering policy are statistically insignificant and negatively associated with RES-E generating capacity. On the other hand, Green Energy Purchasing policy is insignificant in the two-stage model, but significant in the model without predicted values.

Fueling Wisconsin`s economy with renewable energy  

SciTech Connect

A dynamic macroeconomic model of the Wisconsin economy is used to estimate the economic impacts of displacing a portion of future investment in fossil fuel power plants (coal and natural gas) with renewable energy resources (biomass, wind, solar and hydro). The results show that renewable energy investments produce over three times more jobs, income and economic activity than the same amount of electricity generated from coal and natural gas power plants. Between 1995 and 2020, a 75% increase in renewable energy use generates approximately 65,000 more job-years of employment, $1.6 billion in higher disposable income and a $3.1 billion increase in gross regional product than conventional power plant investments. This includes the effects of a 0.3% average annual increase in electricity prices from renewable energy investments.

Technological learning and renewable energy costs: implications for U.S. renewable energy policy.  

SciTech Connect

This paper analyzes the relationship between current renewable energy technology costs and cumulative production, research, development and demonstration expenditures, and other institutional influences. Combining the theoretical framework of 'learning by doing' and developments in 'learning by searching' with the fields of organizational learning and institutional economics offers a complete methodological framework to examine the underlying capital cost trajectory when developing electricity cost estimates used in energy policy planning models. Sensitivities of the learning rates for global wind and solar photovoltaic technologies to changes in the model parameters are tested. The implications of the results indicate that institutional policy instruments play an important role for these technologies to achieve cost reductions and further market adoption.

India has great potential to accelerate use of endowed renewable resources in powering its growing economy with a secure and affordable energy supply. The Government of India recognizes that development of local, renewable resources will be critical to ensure that India is able to meet both economic and environmental objectives and has supported the development of renewable energy through several policy actions. This paper describes the status of renewable energy in India as of DIREC 2010. It begins by describing the institutional framework guiding energy development in India, the main policy drivers impacting energy, and the major policy actions India has taken that impact renewable energy deployment. The paper presents estimates of potential for wind, solar, small hydro, and bioenergy and the deployment of each of these technologies to date in India. The potential for India to meet both large-scale generation needs and provide access to remote, unelectrified populations are covered. Finally, the enabling environment required to facilitate rapid scale of renewables is discussed, including issues of technology transfer and the status of financing in India.

Renewable Energy Opportunities at the Kanto Installations, Japan  

SciTech Connect

This document provides an overview of renewable resource development potential at the U.S. Army installations in the Kanto region in Japan, which includes Camp Zama, Yokohama North Dock, Sagamihara Family Housing Area (SFHA), Sagami General Depot, and Akasaka Press Center. This effort focuses on grid-connected generation of electricity from renewable energy sources and also on ground source heat pumps for heating and cooling buildings. The effort was funded by the Huntsville Army Corps of Engineers, and includes the development of a methodology for renewable resource assessment at Army installations located on foreign soil. The methodology is documented in Renewable Energy Assessment Methodology for Japanese OCONUS Army Installations. The site visit to the Kanto installations took place on April 5 and 6, 2010. At the current time, there are some renewable technologies that show economic potential. Because of siting restrictions and the small size of these installations, development of most renewable energy technologies will likely be limited to Camp Zama. Project feasibility is based on installation-specific resource availability and energy costs and projections based on accepted life-cycle cost methods. Development of any renewable energy project will be challenging, as it will require investigation into existing contractual obligations, new contracts that could be developed, the legality of certain partnerships, and available financing avenues, which involves the U.S. Forces Japan (USFJ), the Government of Japan (GOJ), and a number of other parties on both sides. The Army will not be able to implement a project without involvement and approval from the other services and multiple levels of Japanese government. However, implementation of renewable energy projects could be an attractive method for GOJ to reduce greenhouse gas emissions and lower annual utility payments to USFJ. This report recommends projects to pursue and offers approaches to use. The most promising opportunities include waste-to-energy and ground source heat pumps. Solar photovoltaics (PV) may also prove successful. Other resources were found to be insufficient on the Kanto installations.

Future U.S. water consumption : The role of energy production.  

SciTech Connect

This study investigates how meeting domestic energy production targets for both fossil and renewable fuels may affect future water demand. It combines projections of energy production developed by the U.S. Department of Energy with estimates of water consumption on a per-unit basis (water-consumption coefficients) for coal, oil, gas, and biofuels production, to estimate and compare the domestic freshwater consumed. Although total domestic freshwater consumption is expected to increase by nearly 7% between 2005 and 2030, water consumed for energy production is expected to increase by nearly 70%, and water consumed for biofuels (biodiesel and ethanol) production is expected to increase by almost 250%. By 2030, water consumed in the production of biofuels is projected to account for nearly half of the total amount of water consumed in the production of all energy fuels. Most of this is for irrigation, and the West North Central Region is projected to consume most of this water in 2030. These findings identify an important potential future conflict between renewable energy production and water availability that warrants further investigation and action to ensure that future domestic energy demand can be met in an economically efficient and environmentally sustainable manner.

Energy consumption of personal computer workstations  

SciTech Connect

The explosive growth of the information age has had a profound effect on the appearance of today`s office. Although the telephone still remains an important part of the information exchange and processing system within an office, other electronic devices are now considered required equipment within this environment. This office automation equipment includes facsimile machines, photocopiers, personal computers, printers, modems, and other peripherals. A recent estimate of the installed base indicated that 42 million personal computers and 7.3 million printers are in place, consuming 18.2 billion kWh/yr-and this installed base is growing (Luhn 1992). From a productivity standpoint, it can be argued that this equipment greatly improves the efficiency of those working in the office. But of primary concern to energy system designers, building managers, and electric utilities is the fact that this equipment requires electric energy. Although the impact of each incremental piece of equipment is small, installation of thousands of devices per building has resulted in office automation equipment becoming the major contributor to electric consumption and demand growth in commercial buildings. Personal computers and associated equipment are the dominant part of office automation equipment. In some cases, this electric demand growth has caused office buildings electric and cooling systems to overload.

Analysis of Final Energy Consumption Patterns in 10 Arab Countries  

NASA Astrophysics Data System (ADS)

This study presents an analysis of the energy consumption patterns in 10 Arab countries: Saudi Arabia, Kuwait, United Arab Emirates (UAE), Syria, Lebanon, Jordan, Egypt, Libya, Tunisia, and Algeria. Commonalities and variations between these countries are discussed and explained through key economic and energy indicators, and the relationship between the overall final energy consumption per capita and the GDP per capita is examined. The distribution of the final energy consumption across different sectors is also analysed, and the patterns of consumption in the industrial, transportation, and residential sectors are discussed with focus on the types of energy consumed, and the main drivers of this consumption. The findings and the conclusions of this study are believed to be beneficial to the national energy policy planners in identifying possible strengths, weaknesses, and areas of emphasis and improvement in their strategic energy plans.

A mixed bag: The economic case for renewable energy  

SciTech Connect

Large amounts of renewable energy, including solar, wind, and biomass (wood and plant matter), are available for generating electricity throughout the United States. In some states - especially those in the West and Midwest - the wind and biomass potential alone far exceeds current and foreseeable electricity demand. Moreover, since the 1970s, renewable energy technologies have come down dramatically in cost and have established an impressive record of reliability in grid- and nongrid-connected applications. Despite their promise, however, renewable energy sources are for the most part ignored in utility resource plans. One obstacle is a lack of reliable information about renewable resources and technologies, a problem that is slowly being overcome. Just as important, however, most utility planners fail to recognize the substantial economic benefits of adding renewable energy to their resource mix. In a time of uncertainty about customer load growth, fuel prices, and environmental regulation, renewable energy sources can represent a sound insurance policy against financial losses for utilities and customers alike.

Resource management tools based on renewable energy sources  

NASA Astrophysics Data System (ADS)

Renewable energy is an important source of power for unattended sensors (ground, sea, air), tagging systems, and other remote platforms for Homeland Security and Homeland Defense. Also, Command, Control, Communication, and Intelligence (C3I) systems and technologies often require renewable energy sources for information assurance (IA), in general, and anti-tampering (AT), in particular. However, various geophysical and environmental conditions determine different types of energy harvesting: solar, thermal, vibration, acoustic, hydraulic, wind, and others. Among them, solar energy is usually preferable, but, both a solar habitat and the necessity for night operation can create a need for other types of renewable energy. In this paper, we introduce figures of merit (FoMs) for evaluating preferences of specific energy sources, as resource management tools, based on geophysical conditions. Also, Battery Systemic Modeling is discussed.

Efficiency in energy production and consumption  

NASA Astrophysics Data System (ADS)

This dissertation deals with economic efficiency in the energy industry and consists of three parts. The first examines how joint experience between pairs of firms working together in oil and gas drilling improves productivity. Part two asks whether oil producers time their drilling optimally by taking real options effects into consideration. Finally, I investigate the efficiency with which energy is consumed, asking whether extending Daylight Saving Time (DST) reduces electricity use. The chapter "Learning by Drilling: Inter-Firm Learning and Relationship Persistence in the Texas Oilpatch" examines how oil production companies and the drilling rigs they hire improve drilling productivity by learning through joint experience. I find that the joint productivity of a lead firm and its drilling contractor is enhanced significantly as they accumulate experience working together. Moreover, this result is robust to other relationship specificities and standard firm-specific learning-by-doing effects. The second chapter, "Drill Now or Drill Later: The Effect of Expected Volatility on Investment," investigates the extent to which firms' drilling behavior accords with a key prescription of real options theory: irreversible investments such as drilling should be deferred when the expected volatility of the investments' payoffs increases. I combine detailed data on oil drilling with expectations of future oil price volatility that I derive from the NYMEX futures options market. Conditioning on expected price levels, I find that oil production companies significantly reduce the number of wells they drill when expected price volatility is high. I conclude with "Daylight Time and Energy: Evidence from an Australian Experiment," co-authored with Hendrik Wolff. This chapter assesses DST's impact on electricity demand using a quasi-experiment in which parts of Australia extended DST in 2000 to facilitate the Sydney Olympics. We show that the extension did not reduce overall electricity consumption, but did cause a substantial intra-day shift in demand consistent with activity patterns that are tied to the clock rather than sunrise and sunset.

Modeling renewable energy resources in integrated resource planning  

SciTech Connect

Including renewable energy resources in integrated resource planning (IRP) requires that utility planning models properly consider the relevant attributes of the different renewable resources in addition to conventional supply-side and demand-side options. Otherwise, a utility`s resource plan is unlikely to have an appropriate balance of the various resource options. The current trend toward regulatory set-asides for renewable resources is motivated in part by the perception that the capabilities of current utility planning models are inadequate with regard to renewable resources. Adequate modeling capabilities and utility planning practices are a necessary prerequisite to the long-term penetration of renewable resources into the electric utility industry`s resource mix. This report presents a review of utility planning models conducted for the National Renewable Energy Laboratory (NREL). The review examines the capabilities of utility planning models to address key issues in the choice between renewable resources and other options. The purpose of this review is to provide a basis for identifying high priority areas for advancing the state of the art.

Secondary School Teachers' Knowledge and Attitudes Towards Renewable Energy Sources  

NASA Astrophysics Data System (ADS)

Investigating knowledge, perceptions as well as attitudes of public that concern various aspects of environmental issues is of high importance for Environmental Education. An integrated understanding of these parameters can properly support the planning of Environmental Education curriculum and relevant educational materials. In this survey we investigated knowledge and attitudes of secondary school teachers in Greece towards renewable energy sources, particularly wind and solar energy systems. A questionnaire with both open and close questions was used as the main methodological instrument. Findings revealed that although teachers were informed about renewable energy sources and well disposed towards these sources, they hardly expressed clear positions regarding several issues about wind and solar energy technologies and farms. Moreover such themes are limited integrated in teaching either as extra curricular educational programs or through the curriculum. These findings cannot confirm that teachers could influence students' opinion towards renewable energy systems. Thus, authorities should invest more in Environmental Education and relevant Teachers' Education.

Role of Energy Storage with Renewable Electricity Generation  

SciTech Connect

Renewable energy sources, such as wind and solar, have vast potential to reduce dependence on fossil fuels and greenhouse gas emissions in the electric sector. Climate change concerns, state initiatives including renewable portfolio standards, and consumer efforts are resulting in increased deployments of both technologies. Both solar photovoltaics (PV) and wind energy have variable and uncertain (sometimes referred to as intermittent) output, which are unlike the dispatchable sources used for the majority of electricity generation in the United States. The variability of these sources has led to concerns regarding the reliability of an electric grid that derives a large fraction of its energy from these sources as well as the cost of reliably integrating large amounts of variable generation into the electric grid. In this report, we explore the role of energy storage in the electricity grid, focusing on the effects of large-scale deployment of variable renewable sources (primarily wind and solar energy).
