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

  2. Energy conservation opportunities: audit vis-a-vis mine productivity

    Mining operation, whether opencast or underground, with modern equipment is highly energy intensive, needing energy conservation and management to ensure efficiency, cost effectiveness, and overall productivity. Exhaustible primary energy resources such as coal, lignite, oil, and nuclear fuels are being mined out to meet our energy needs. An attempt has been made in this paper to highlight the energy conservation opportunities, energy audit, the relevant Energy Conservation Act 2001 and certain energy saving measures leading to higher productivity followed by a few case study examples. 3 refs.

    Developing countries like India, has to cater the imbalance of energy between the supply and demand in almost all the sectors, so as to devise energy conservation strategies. Electricity is one of the most convenient form of energy gifted to the mankind. The raising cost of electricity and the need to raise large resources to meet the required demand is only at the most of other important assets of the country. This gap between demand and supply can be partially met by appropriate energy conservation schemes through energy audit- a scientific approach for balancing the supply and demand. India has to go a long way ahead in it, therefore, energy audit has been initiated at vulnerable energy consuming places. This paper presents the effectiveness of energy audit strategy in achieving energy conservation. The energy audit of Shrama Shakti Bhavan, an office complex at New Delhi, has been taken as a case study for this work. (author). 2 refs., 12 tabs

    The widespread practice of conservation could make a substantial reduction in the rate of growth of demand and hence in the rate at which resources need to be developed and consumed. An attempt is not made to show that conservation is an alternative to increasing energy supply. After reviewing the consumption of energy before the 1973 energy crisis, the main features of conservation which have brought it to the forefront of energy policy are examined. Some information on present consumption patterns in New Zealand is presented.

    Expanding energy conservation and efficiency in every sector nationwide is one of the most cost-effective instruments for reducing US energy imports, the trade deficit and energy's environmental impacts. For these reasons, energy conservation and efficiency have been essential elements of US energy policy since the oil embargos and price spikes of the 1970s. The Energy Independence and Security Act of 2007 (EISA) is the latest federal legislation to expand and strengthen US energy conservation and efficiency policies, programs, and practices. Specifically, EISA and its recent predecessor, the Energy Policy Act of 2005 (EPAct05), contain almost 200 titles with new provisions for energy conservation and efficiency aimed at improvements in vehicle fuel economy. These provisions include efficiency of appliances and lighting; energy savings in residential, commercial, and government buildings; the efficiency of industrial manufacturing plants; and the efficiency of electric power delivery and end-use. These actions have begun to contribute to new federal, state, and local policies, programs, and practices across the US, and expectations are high for increases in the level of energy savings. This paper summarizes the history of US energy conservation and efficiency policies, outlines EISA's and EPAct05's key provisions, and considers prospects for the future. (author)

  9. Real world financing opportunities for energy conservation projects

    1988-01-01

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

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

    A simple model is presented to assess the thermal performance of a cement industry with an integrated view to improve the productivity of the plant. The model is developed on the basis of mass, energy and exergy balance and is applied to an existing Portland cement industry in Indonesia. The data obtained from industry show that the burning efficiency and the second law efficiency of the kiln system are 52.07% and 57.07% respectively. Cooler efficiency and heat recovery efficiency are 47.75% and 51.2% respectively. The unaccounted loss at kiln system was found to be 1.85% and that of cooler system was 19%. The high loss at cooler was mainly due to the convection and radiation losses from the uninsulated cooler. Irreversibility of the system was found to be about 20%, which is due to the conversion from chemical to thermal energy. The thermal energy conservation opportunities are identified. This study show that by replacing industrial diesel oil (IDO) with waste heat recovery from kiln and cooler exhaust for drying of raw meal and fuel, and preheating of combustion air, a cement industry in Indonesia can save about 1.264 x 10 5 US dollars per year

    Cement production process has been highly energy and cost intensive. The cement plant requires 8784 h per year of the total operating hours to produce 640,809 tonnes of clinker. To achieve effective and efficient energy management scheme, thermal energy audit analysis was employed on the pyroprocessing unit of the cement plant. Fuel combustion generates the bulk of the thermal energy for the process, amounting to 95.48% (4164.02 kJ/kg cl ) of the total thermal energy input. Thermal efficiency of the unit stands at 41%, below 50-54% achieved in modern plants. The exhaust gases and kiln shell heat energy losses are in significant quantity, amounting to 27.9% and 11.97% of the total heat input respectively. To enhance the energy performance of the unit, heat losses conservation systems are considered. Waste heat recovery steam generator (WHRSG) and Secondary kiln shell were studied. Power and thermal energy savings of 42.88 MWh/year and 5.30 MW can be achieved respectively. Financial benefits for use of the conservation methods are substantial. Environmental benefit of 14.10% reduction in Greenhouse gases (GHG) emissions could be achieved.

    Oceans, particularly coastal areas, are getting busier and within this increasingly human-dominated seascape, marine biodiversity continues to decline. Attempts to maintain and restore marine biodiversity are becoming more spatial, principally through the designation of marine protected areas (MPAs). MPAs compete for space with other uses, and the emergence of new industries, such as marine renewable energy generation, will increase competition for space. Decision makers require guidance on how to zone the ocean to conserve biodiversity, mitigate conflict and accommodate multiple uses. Here we used empirical data and freely available planning software to identified priority areas for multiple ocean zones, which incorporate goals for biodiversity conservation, two types of renewable energy, and three types of fishing. We developed an approached to evaluate trade-offs between industries and we investigated the impacts of co-locating some fishing activities within renewable energy sites. We observed non-linear trade-offs between industries. We also found that different subsectors within those industries experienced very different trade-off curves. Incorporating co-location resulted in significant reductions in cost to the fishing industry, including fisheries that were not co-located. Co-location also altered the optimal location of renewable energy zones with planning solutions. Our findings have broad implications for ocean zoning and marine spatial planning. In particular, they highlight the need to include industry subsectors when assessing trade-offs and they stress the importance of considering co-location opportunities from the outset. Our research reinforces the need for multi-industry ocean-zoning and demonstrates how it can be undertaken within the framework of strategic conservation planning. Copyright © 2015 Elsevier Ltd.

  20. Selling energy conservation.

    Science.gov (United States)

    Hinrichsen, D

    1995-01-01

    This article concerns the Organization of the Petroleum Exporting Countries (OPEC) crisis and its impact on energy efficiency measures in the US. In 1985, when the OPEC collapsed, the US government had avoided the need to construct 350 gigawatts of new electric capacity. The most successful efficiency improvements, especially in household appliances and equipment, lighting and tightened energy efficiency standards in new buildings, resulted from the OPEC event. The real innovation of that time was the change in profit rules for utilities. This revolution and the way some US utilities view energy have not caught on elsewhere. Despite the initiative toward improving energy efficiency in homes, offices and industries, the change has been slow. Partly to blame are the big development banks, which pointed out that short-term conservation and efficiency measures could save at least 15% of the total energy demand without the need for major investment. The benefits of energy conservation was shown during the oil shock when per capita energy consumption fell by 5% in the member states of the Organization of Economic Cooperation and Development, while the per capita gross domestic product grew by a third. There has been a decrease in energy expenditure worldwide, and the scope for further energy savings is enormous, but governments need to recognize and seize the opportunity.

    ALINET is a network model designed for the analysis of energy use in the food processing and distribution sector and for the evaluation of the potential effectiveness of energy conserving technologies. The conceptual framework of the model, as well as the design and implementation of the computer software are described. The wheat system at the national, state, and facility-specific level is used to illustrate the model's operation and use. A pilot project, carried out in cooperation with industry, is described in which energy use in (a) hard wheat milling, and (b) durum milling and pasta manufacture is analyzed. Finally, the introduction of an alternative technology for pasta drying is assessed in terms of energy conservation and cost. Recommendation for further applications and institutionalization of the model are made.

  2. Japan's energy conservation policy

    International Nuclear Information System (INIS)

    Yoda, Kenichi

    1990-01-01

    This article reviews developments in Japanese energy conservation since the 1970s. The industrial sector has achieved the greatest success, due to industrial restructuring as well as improvements in energy efficiency. In the residential/commercial sector, the efficiency of appliances has been much improved. Although improvements have been made in the fuel efficiency of passenger cars, energy consumption in the transportation sector has risen slightly owing to increased transport of passengers and freight. The overall responsibility for energy conservation policy rests with the Ministry of International Trade and Industry. MITI is also responsible for implementing specific conservation policies in regard to the industrial and commercial sectors. In the residential sector, MITI works with the Ministry of Construction and in the transportation sector with the Ministry of Transport. To realize the goals of energy conservation policy through general research, dissemination of public information and other activities, MITI works with the Energy Conservation Center (ECC).

    The nature of conservation challenges can foster a reactive, rather than proactive approach to decision making. Failure to anticipate problems before they escalate results in the need for more costly and time-consuming solutions. Proactive conservation requires forward-looking approaches to decision making that consider possible futures without being overly constrained by the past. Strategic foresight provides a structured process for considering the most desirable future and for mapping the most efficient and effective approaches to promoting that future with tools that facilitate creative thinking. The process involves 6 steps: setting the scope, collecting inputs, analyzing signals, interpreting the information, determining how to act, and implementing the outcomes. Strategic foresight is ideal for seeking, recognizing, and realizing conservation opportunities because it explicitly encourages a broad-minded, forward-looking perspective on an issue. Despite its potential value, the foresight process is rarely used to address conservation issues, and previous attempts have generally failed to influence policy. We present the strategic foresight process as it can be used for proactive conservation planning, describing some of the key tools in the foresight tool kit and how they can be used to identify and exploit different types of conservation opportunities. Scanning is an important tool for collecting and organizing diverse streams of information and can be used to recognize new opportunities and those that could be created. Scenario planning explores how current trends, drivers of change, and key uncertainties might influence the future and can be used to identify barriers to opportunities. Backcasting is used to map out a path to a goal and can determine how to remove barriers to opportunities. We highlight how the foresight process was used to identify conservation opportunities during the development of a strategic plan to address climate change in New York

  4. Evolving concepts and opportunities in soil conservation

    Julian Dumanski

    2015-03-01

    The paper discusses some of the new driving forces, new international programs, and new potential partners in soil conservation. Increasingly, international efforts to mitigate land degradation are shifting from studies of the biophysical processes to improving the global, national and local enabling policy environment, as well as mainstreaming of soil conservation into national and regional policies and programs. Also, increased emphasis is placed on economic instruments and international markets, such as carbon trading, and incorporation of non-market values in ecosystem investment, such as payment for ecosystem services, certification schemes, etc. The paper discusses some of the opportunities for soil conservation that accrue from these new driving forces.

    Energy audit is a very effective management tool for betterment of plant performance. The energy audit has a problem solving approach rather than a fault finding technique. The energy conservation is a rational use of energy. It has been the experience of the developed countries that energy is one issue which results into cost savings with relatively much less efforts/cost in comparison with other resources used in production, development and adoption of energy efficiency equipment and practices in most of production process has been the result of same technique.

  7. Promoting household energy conservation

    International Nuclear Information System (INIS)

    Steg, Linda

    2008-01-01

    It is commonly assumed that households must change their behaviour to reduce the problems caused by increasing levels of fossil energy use. Strategies for behaviour change will be more effective if they target the most important causes of the behaviour in question. Therefore, this paper first discusses the factors influencing household energy use. Three barriers to fossil fuel energy conservation are discussed: insufficient knowledge of effective ways to reduce household energy use, the low priority and high costs of energy savings, and the lack of feasible alternatives. Next, the paper elaborates on the effectiveness and acceptability of strategies aimed to promote household energy savings. Informational strategies aimed at changing individuals' knowledge, perceptions, cognitions, motivations and norms, as well as structural strategies aimed at changing the context in which decisions are made, are discussed. This paper focuses on the psychological literature on household energy conservation, which mostly examined the effects of informational strategies. Finally, this paper lists important topics for future research

  9. Why not energy conservation?

    International Nuclear Information System (INIS)

    Carlson, Shawn

    2016-01-01

    Energy conservation is a deep principle that is obeyed by all of the fundamental forces of nature. It puts stringent constraints on all systems, particularly systems that are ‘isolated,’ meaning that no energy can enter or escape. Notwithstanding the success of the principle of stationary action, it is fair to wonder to what extent physics can be formulated from the principle of stationary energy. We show that if one interprets mechanical energy as a state function, then its stationarity leads to a novel formulation of classical mechanics. However, unlike Lagrangian and Hamiltonian mechanics, which deliver their state functions via algebraic proscriptions (i.e., the Lagrangian is always the difference between a system’s kinetic and potential energies), this new formalism identifies its state functions as the solutions to a differential equation. This is an important difference because differential equations can generate more general solutions than algebraic recipes. When applied to Newtonian systems for which the energy function is separable, these state functions are always the mechanical energy. However, while the stationary state function for a charged particle moving in an electromagnetic field proves not to be energy, the function nevertheless correctly encodes the dynamics of the system. Moreover, the stationary state function for a free relativistic particle proves not to be the energy either. Rather, our differential equation yields the relativistic free-particle Lagrangian (plus a non-dynamical constant) in its correct dynamical context. To explain how this new formalism can consistently deliver stationary state functions that give the correct dynamics but that are not always the mechanical energy, we propose that energy conservation is a specific realization of a deeper principle of stationarity that governs both relativistic and non-relativistic mechanics.

  10. Energy conservation technologies

    Energy Technology Data Exchange (ETDEWEB)

    Courtright, H.A. [Electric Power Research Inst., Palo Alto, CA (United States)

    1993-12-31

    The conservation of energy through the efficiency improvement of existing end-uses and the development of new technologies to replace less efficient systems is an important component of the overall effort to reduce greenhouse gases which may contribute to global climate change. Even though uncertainties exist on the degree and causes of global warming, efficiency improvements in end-use applications remain in the best interest of utilities, their customers and society because efficiency improvements not only reduce environmental exposures but also contribute to industrial productivity, business cost reductions and consumer savings in energy costs.

  11. Energy Efficiency: Finding Leadership Opportunities

    Directory of Open Access Journals (Sweden)

    Full Text Available Between 1995 and 2011, the population of Alberta increased by roughly 40 per cent, but energy use in the province grew much faster, with a 62 per cent increase over the same period. In the industrial sector, the province’s largest energy consumer, demands grew 110 per cent. In mining and oil-and-gas extraction specifically, energy use over that period soared, growing by 355 per cent. That remarkable growth in energy consumption creates a particular challenge for Alberta Premier Alison Redford, who in 2011 ordered her ministers to develop a plan that “would make Alberta the national leader in energy efficiency and sustainability.” The province is still waiting. The incentives to become more energy efficient are not particularly strong in Alberta. The province’s terrain and size favour larger and less-efficient vehicles. Energy in the province is abundant, so there is little cause for concern over energy security. And energy is relatively affordable, particularly for a population that is more affluent than the Canadian average. There is little pressure on Albertans to radically alter their energy consumption behaviour. Yet, improved energy efficiency could position businesses in Alberta to become even more globally competitive, in addition to leading to improved air quality and public health. And for a province racing to keep up with growing energy demand, effective measures that promote conservation will prove much cheaper than adding yet more expensive infrastructure to the energy network. Many other jurisdictions have already provided examples of methods Alberta could employ to effectively promote energy conservation. First, Alberta must set hard targets for its goals to save energy, and then monitor that progress through transparent accounting, measuring and reporting. The provincial government can also nurture a culture of energy conservation, by formally and publicly recognizing leadership in efficiency improvements in industry and

    High rates of inflation combined with social justice against a backdrop of ever increasing population- this is a challenge which the Government of India is facing today. It is evident that the annual growth rate of 5.6% as envisaged for the VIIIth five year plan can never be met unless conscious efforts are made to augment energy supplies by energy demand management through energy conservation. In this context, a review of the energy consuming sectors in terms of their consumption trends, energy efficiencies or intensities, energy conservation opportunities, technologies used and energy investment programmes would prove useful and informative.

  13. Energy conservation in SIMMER

    International Nuclear Information System (INIS)

    Arnold, L.A.; Knowles, J.B.

    1983-11-01

    The SIMMER code contains models of the many interacting thermo-hydraulic processes that occur during a hypothetical core disruptive accident (HCDA), to provide an overall picture from accident initiation to containment loading. In calculations of roof loadings following the HCDA, errors in computing the overall energy balance were found to be up to ten times the kinetic energy of the sodium slug which creates the loading. On this account, the results were considered to be seriously compromised. This report describes a systematic investigation into the effect, nature and origin of the energy discrepancies. Its main conclusion are that, the errors stem from a systematic rather than a random source, energy errors for individual cells can be two decades larger than the mean value provided by the code, and cellular mass and energy errors are strongly correlated and they can actually increase when the mesh is refined. A likely cause of the conservation errors is identified as the solution of the liquid phase mass and energy equations at effectively different time instants during each timestep. (author)

  17. Energy conservation policy in China

    Haugland, T; Roland, K [ECON-Centre for Economic Analysis, Oslo (NO)

    1992-02-01

    Energy market developments and the state of the environment will be decisive for economic growth and modernization of Chinese society. Lack of adequate energy supplies could in the future seriously impair the growth potential of the economy, as it has partly done during the 1980s. Environmental damage creates major health problems for the population and hamper the productive capacity of Chinese agriculture and industry. One obvious and effective measure to meet these challenges is a policy that pursues more efficient use of energy supplies. China achieved impressive results in energy efficiency improvements during the 1980s, largely on the back of the cheapest and most obvious conservation opportunities. These are now exhausted. Further improvements will require stronger measures. It is difficult to see how the current rate of economic growth (above 6 per cent) and energy efficiency improvements can be sustained without comprehensive market reforms. Economic growth and development is however, in Chinese policy, subordinate to political stability and continuity. The disruption of the political and economic reform processes in 1988-9 was largely motivated by a perceived fear of political instability and disintegration of the state. Thus, there may exist some degree of conflict between the objective of strong economic growth and the existing 'social order and stability'. To balance the potential conflict inherent in this development process is the big challenge facing Chinese society for the coming decades. (author).

    1979-07-01

    Some ways in which energy is wasted in industry are discussed and the losses involved are quantified. Reference is made to a particular loss in annealing furnaces; wasted energy in factory and lighting systems; heat generated by motors and lighting and by such processes as welding; unlagged hot pipework and most hot processes; and poor building envelope features. It is concluded that an industry should declare its intention of conservation at the highest possible level, identify conservation as a manufacturing target, and invest the responsibility in people for whom it is a full-time activity.

    The total annual CO 2 emissions associated with the energy consumption of the major retail food outlets in the UK amount to around 4.0 MtCO 2 . The energy consumption and emissions from supermarkets varies widely and can depend on many factors such as the type and size of the store, business and merchandising practices and refrigeration and environmental control systems used. This paper provides energy consumption data of a sample of 2570 retail food stores from a number of major retail food chains in the UK. The sample covers all major store categories from convenience stores to hypermarkets and includes approximately 30% of the total number of stores in the UK having a net sales area more than 280 m 2 . The data show a wide variability of energy intensity even within stores of the same retail chain. A power law can be used to describe the variation of the average electrical energy intensity of the stores in the sample with sales area. If the electrical intensity of the stores above the average is reduced to the average by energy conservation measures, annual energy savings of the order of 10% or 840 GWh can be achieved representing 355,000 tonnes annual reduction in CO 2 emissions. The paper also discusses the major energy consuming processes in retail food stores and identifies opportunities for energy savings. - Research highlights: → Energy consumption by supermarkets in the UK is significant and a wide variability exists between stores of similar size. → Energy conservation measures to reduce energy consumption of individual stores to the average can produce a0% energy savings. → Significant opportunities for energy savings exist from the integration of HVAC and refrigeration equipment.

    In the electricity sector, energy conservation through technological and behavioral change is estimated to have a savings potential of 123 million metric tons of carbon per year, which represents 20% of US household direct emissions in the United States. In this article, we investigate the effectiveness of nonprice information strategies to motivate conservation behavior. We introduce environment and health-based messaging as a behavioral strategy to reduce energy use in the home and promote energy conservation. In a randomized controlled trial with real-time appliance-level energy metering, we find that environment and health-based information strategies, which communicate the environmental and public health externalities of electricity production, such as pounds of pollutants, childhood asthma, and cancer, outperform monetary savings information to drive behavioral change in the home. Environment and health-based information treatments motivated 8% energy savings versus control and were particularly effective on families with children, who achieved up to 19% energy savings. Our results are based on a panel of 3.4 million hourly appliance-level kilowatt-hour observations for 118 residences over 8 mo. We discuss the relative impacts of both cost-savings information and environmental health messaging strategies with residential consumers.

    Computerized Face Detection, is concerned with the difficult task of converting a video signal of a person to written text. It has several applications like face recognition, simultaneous multiple face processing, biometrics, security, video surveillance, human computer interface, image database management, digital cameras use face detection for autofocus, selecting regions of interest in photo slideshows that use a pan-and-scale and The Present Paper deals with energy conservation using face detection. Automating the process to a computer requires the use of various image processing techniques. There are various methods that can be used for Face Detection such as Contour tracking methods, Template matching, Controlled background, Model based, Motion based and color based. Basically, the video of the subject are converted into images are further selected manually for processing. However, several factors like poor illumination, movement of face, viewpoint-dependent Physical appearance, Acquisition geometry, Imaging conditions, Compression artifacts makes Face detection difficult. This paper reports an algorithm for conservation of energy using face detection for various devices. The present paper suggests Energy Conservation can be done by Detecting the Face and reducing the brightness of complete image and then adjusting the brightness of the particular area of an image where the face is located using histogram equalization.

    As a cost-effective solution to energy conservation, behavior based method focuses on changing people's behavior through normative feedback for energy efficiency. While the application of behavior-based method is promising, the challenge exists to achieve efficiently sustainable behavioral change. Based on multi-period observation of energy behavior at the Joint Base Andrews in Maryland, this paper presents a model-based approach aimed to improve the nationally popular and deep-seated benchmark setting strategy for normative feedback used in home energy reports. The improved approach has its merits of countering the undesirable boomerang effect and enhancing the effectiveness of normative feedback targeting different personalities. By introducing a modified opinion dynamics model, this paper simulates the process of energy behavior change and therefore identifies the driver and elementary rules of behavioral change. In particular, the paper defines various behavioral zones in accordance with people's personality and proposes a new customized energy reporting mechanism that maps normative benchmark to personality trait. The new energy reporting policy has strong industrial implication for promoting behavior-based method towards a sustained energy conservation movement. -- Highlights: •We explore the personality driving resident behavior change under peer pressure. •We map the distribution of behavior clusters driven by personality and benchmarks. •The model is tested using data from an experiment conducted in Maryland, U.S. •The population exposed to normative feedback can be divided into six categories. •A personality trait-based home energy reporting mechanism is proposed

Sun, water, biomass and geothermal fields main non conventional energy sources with commercial applications, are presents and in some cases plentiful in national territory. Moreover the coastal tidal power which is in research stage in several countries. Non conventional energy sources are an alternative which allow us to reduce the consumption of hydrocarbons or any other type of primary energetic, are not by oneself choices for the energy conservation, but energy replacements. At the beginning of this year, CONAE created the Direction of Non conventional Energy Sources, which main objective is to promote and impulse programs inclined towards the application of systems based in renewable energy sources. The research centers represent a technological and consultative support for the CONAE. They have an infrastructure developed along several years of continuous work. The non conventional energy sources will be a reality at the same time that their cost be equal or lower than the cost for the traditional generating systems.

    Opportunities for conserving energy and water, as well as reducing waste, within the 24,000 establishment-strong food service sector in Ontario are identified. Operators are encouraged to take advantage of these opportunities to lower their costs while conserving valuable resources at the same time. In preparing this guide, site visits were carried out at six food service facilities in Ontario. Information about how much money is generally spent on energy, water and waste management by food service operators is provided. The amount and type of waste generated by these facilities is also described. The volatility of the commercial food service market place was identified as one of the major impediments to energy conservation. It was found that most owners of the food service facilities make business decisions based on the lowest first costs, irrespective of longer-term energy efficiency and operating costs. 31 refs., 13 tabs., 9 figs., 4 appendices.

  3. Psychological dimensions of Energy Conservation

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available One of the most serious current environmental problems is the depletion of non renewable natural resources. The vast majority of our daily actions involve the consumption of energy and they increase the problem. Environmental psychology studies the psychological motivations that determine pro-ecological behaviour. In this context the aim of this review was to determine which psychological models and variables are better descriptors of residential energy conservation, comparing the predictive power of different models related to behaviour, residential consumption as well as to the acceptability of energy policies. Results suggest that energy saving is mainly linked to altruistic motivations, followed by egoistic reasons and in a minor way to environmental concerns. People would act according to these dimensions when contextual conditions are perceived as appropriate.

    The annual production of foodgrains in India rose from 50.8 million tonnes in 1950-51 to 178 million tonnes in 1989-90. One of the factors which led to this impressive growth is the continued increase in input of mechanization and energy in the agricultural sector by way of tractors running on diesel and pumps (for water supply) based on diesel and electricity. Electricity consumption in agricultural sector rose from 833 million kWh in 1960-61 to 47000 million kWh in 1990-91 and is further expected to rise to 81.8 TWH in 1999-2000. Considering the heavy investments required for production and supply of energy, it has become imperative to avoid wasteful use of energy and to use energy more efficiently. This can be done by : (1) Changing the electricity tariff structure from the present horse power related rates to energy consumption related rates. This will induce farmers to avoid waste in energy use. (2) Adopting energy efficiency measures. These measures are : (1) replacement of inefficient foot valves, suction pipes and delivery pipes of the pump sets, (2) increasing power factor of electric motors used for pumps sets, (3) reducing distribution losses over LT lines, and (4) optimizing use of fertilizers. This optimization will indirectly conserve energy by reducing electricity consumption by fertilizer industry. (M.G.B.). 5 refs., 4 tabs

    In this Letter, we consider the possibility of reconciling metric theories of gravitation with a violation of the conservation of energy-momentum. Under some circumstances, this can be achieved in the context of unimodular gravity, and it leads to the emergence of an effective cosmological constant in Einstein's equation. We specifically investigate two potential sources of energy nonconservation-nonunitary modifications of quantum mechanics and phenomenological models motivated by quantum gravity theories with spacetime discreteness at the Planck scale-and show that such locally negligible phenomena can nevertheless become relevant at the cosmological scale.

    Large, intact areas of tropical peatland are highly threatened at a global scale by the expansion of commercial agriculture and other forms of economic development. Conserving peatlands on a landscape scale, with their hydrology intact, is of international conservation importance to preserve their distinctive biodiversity and ecosystem services and maintain their resilience to future environmental change. We explored threats to and opportunities for conserving remaining intact tropical peatlands; thus, we excluded peatlands of Indonesia and Malaysia, where extensive deforestation, drainage, and conversion to plantations means conservation in this region can protect only small fragments of the original ecosystem. We focused on a case study, the Pastaza-Marañón Foreland Basin (PMFB) in Peru, which is among the largest known intact tropical peatland landscapes in the world and is representative of peatland vulnerability. Maintenance of the hydrological conditions critical for carbon storage and ecosystem function of peatlands is, in the PMFB, primarily threatened by expansion of commercial agriculture linked to new transport infrastructure that is facilitating access to remote areas. There remain opportunities in the PMFB and elsewhere to develop alternative, more sustainable land-use practices. Although some of the peatlands in the PMFB fall within existing legally protected areas, this protection does not include the most carbon-dense (domed pole forest) areas. New carbon-based conservation instruments (e.g., REDD+, Green Climate Fund), developing markets for sustainable peatland products, transferring land title to local communities, and expanding protected areas offer pathways to increased protection for intact tropical peatlands in Amazonia and elsewhere, such as those in New Guinea and Central Africa which remain, for the moment, broadly beyond the frontier of commercial development. © 2017 The Authors.

    Africa, a continent exceptionally rich in biodiversity, is rapidly urbanizing. Africa’s urbanization is manifest in the growth of its megacities as well as that of its smaller towns and cities. The conservation planning and practice will increasingly need to account for direct and indirect impacts of the continent’s urbanization. The objective of our study is to pinpoint the outstanding challenges and opportunities afforded by the growing cities on the continent to the conservation goals and practices. While there have been many studies on the impacts of urbanization and development on conservation in Africa these studies tended to focus on specific issues. Here, we provide a synthesis of this body of work supported by new analysis. Urban areas, growing both in population and in land cover, pose threats to the integrity of the continent’s ecosystems and biodiversity but their growth also create opportunities for conservation. The burgeoning urban populations, especially in Sub-Saharan Africa, increase the strain on already insufficient infrastructure and bring new governance challenges. Yet, Africa’s ecosystems can serve as foundations for green infrastructure to serve the needs of its urban populations while safeguarding fragile biodiversity. Overall, while worsening social problems overshadow the concerns for biodiversity there are also promising initiatives to bring these concerns into the fold to address social, institutional, and ecological challenges that emerge with the continued urbanization of the continent.

    The plant-wide energy assessment at W. R. Grace's Curtis Bay Works helped identify four projects with combined potential savings of $840,000 per year. A separate, unique project that would partner W. R. Grace with the City of Baltimore to recover and use landfill gas (methane) to cogenerate steam and electricity was also identified during the assessment. If implemented, the project would recover gas from the landfill to replace 40% of the electricity and 65% of the fuel currently required to produce steam at Curtis Bay Works. Annual savings are estimated at $900,000 to $1.2 million.

    This paper discusses the potential for energy and power savings that exist in electric power delivery systems. These savings translate into significant financial and environmental benefits for electricity producers and consumers as well as for society in general. AlliedSignal's knowledge and perspectives on this topic are the result of discussions with hundreds of utility executives, government officials and other industry experts over the past decade in conjunction with marketing our Amorphous Metal technology for electric distribution transformers. Amorphous metal is a technology developed by AlliedSignal that significantly reduces the energy lost in electric distribution transformers at an incremental cost of just a few cents per kilo-Watt-hour. The purpose of this paper is to discuss: Amorphous Metal Alloy Technology; Energy Savings Opportunity; The Industrial Barriers and Remedies; Worldwide Demand; and A Low Risk Strategy. I wish this presentation will help KEPCO achieve their stated aims of ensuring sound development of the national economy and enhancement of public life through the economic and stable supply of electric power. AlliedSignal Korea Ltd. in conjunction with AlliedSignal Amorphous Metals in the U.S. are here to work with KEPCO, transformer manufacturers, industry, and government agencies to achieve greater efficiency in power distribution

    In the ninth-five year plan of China, the socialist market economy model will be developed. In the stage of transferring from planning economy to market economy, the energy conservation technology services industry in China has met new challenges. Over the past ten to fifteen years, there has developed a new mechanism for financing energy efficiency investments in market economies. The process is simple. After inspecting an enterprise or an entity for energy saving opportunities, an Energy Service Company (ESCO) which business aimed at making money will review the recommended energy conservation opportunities with the enterprise or the entity (user) and implement those measures acceptable to the user at no front end cost to the user. The ESCO then guarantees that the energy savings will cover the cost of the capital renovations using the Performance Contracting.

  1. Opportunities in Canada's growing wind energy industry

    International Nuclear Information System (INIS)

    Lovshin Moss, S.; Bailey, M.

    2006-01-01

    Investment in Canada's wind sector is projected to reach $8 billion by 2012, and growth of the sector is expected to create over 16,000 jobs. Canada's wind energy capacity grew by 54 per cent in 2005 alone, aided in part by supportive national policies and programs such as the Wind Power Production Incentive (WPPI); the Canadian Renewable Conservation Expense (CRCE) and Class 43.1 Capital Cost Allowance; and support for research and development. Major long-term commitments for clean power purchases, standard offer contracts and renewable portfolio standards in several provinces are encouraging further development of the wind energy sector. This paper argued that the development of a robust Canadian wind turbine manufacturing industry will enhance economic development, create opportunities for export; and mitigate the effects of international wind turbine supply shortages. However, it is not known whether Canadian wind turbine firms are positioned to capitalize on the sector's recent growth. While Canada imports nearly all its large wind turbine generators and components, the country has technology and manufacturing strengths in advanced power electronics and small wind systems, as well as in wind resource mapping. Wind-diesel and wind-hydrogen systems are being developed in Canada, and many of the hybrid systems will offer significant opportunities for remote communities and off-grid applications. Company partnerships for technology transfer, licensing and joint ventures will accelerate Canada's progress. A recent survey conducted by Industry Canada and the Canadian Wind Energy Association (CanWEA) indicated that the total impact of wind energy related expenditures on economic output is nearly $1.38 billion for the entire sector. Annual payroll for jobs in Canada was estimated at $50 million, and substantial employment growth in the next 5 years is expected. Canada offers a strong industrial supply base capable of manufacturing wind turbine generators and

    2017-01-01

    China is undergoing rapid industrialization and urbanization, with consequent dramatic increase in energy demand. Given energy scarcity, environmental pollution, energy security and energy cost constraints, energy conservation will be the major strategy in China's transition to a low-carbon economy. Since the metallurgy industry is a main sector of energy consumption, the efficiency of energy conservation in this industry will affect the future prospects of energy savings. This paper analyzes the energy conservation potential of China's metallurgy industry. First, seemingly unrelated regression method is applied to investigate the relationship between energy relative price, R&D input, enterprise ownership structure, enterprise scale and energy intensity of the metallurgy industry. Then, based on the SUR results, we use the scenario analysis method to predict energy consumption and savings potential in the industry in different scenarios. This paper provides references for China's government and metallurgy industry in formulating relevant energy conservation policies. - Highlights: • Seemingly unrelated regression method is applied to analyze the energy intensity of metallurgy industry. • We use the scenario analysis method to predict energy consuming and energy saving of Chinese metallurgy industry. • Provide references for China's government and metallurgy industry in formulating relevant energy conservation policies.

  6. Wind energy, status and opportunities

    International Nuclear Information System (INIS)

    Van Wijk, A.

    1994-01-01

    Wind energy is diffuse but was widely used before the industrial revolution. The first oil crisis triggered renewed interest in wind energy technology in remote areas. Winds develop when solar radiation reaches the earth's highly varied surface unevenly, creating temperature density and pressure differences. The earth's atmosphere has to circulate to transport heat from the tropics towards the poles. On a global scale, these atmospheric currents work as an immense energy transfer medium. Three main applications can be distinguished: wind pumps, off-grid applications and grid-connected applications. The total generating costs for wind turbine systems are determined by total investments costs, the life time, the operating and maintenance costs, the wind regime (the wind energy potential is proportional to v 3 where v is the wind speed), the efficiency and availability of the wind turbine. The main gains are achieved as a result of improved reliability. The optimum size of a wind turbine depends on the wind speed, the wind turbine costs, the construction costs, the environmental impact and the social costs. The value of wind energy depends on the application that is made of the energy generated and on the costs of alternatives, it can be calculated by the avoided costs of damage to flora, fauna and mankind due to acid rain deposition, enhancement of the greenhouse effect. The environmental aspects are bird hindrance, noise, telecommunication interference and safety. 2 tabs., 1 fig

    This plan outlined details of Nova Scotia's proposed $5 million incremental investment in energy efficiency and conservation measures in 2006. The plan was developed through consultation with various Canadian utilities, customers and external stakeholders. A team of stakeholders identified lighting, pricing, partnerships and education as opportunities offering the greatest potential for results. Market research was conducted to identify market potential and the identification of barriers to customer adoption of programs as well as customer expectations regarding program implementation. It was anticipated that the plan will reduce electricity usage and result in significant savings for customers, as well as reducing greenhouse gas (GHG) emissions. The aim of the plan is to help build a conservation and energy efficiency culture in Nova Scotia and to bring Nova Scotia Power together with community-based partners. Specific plans for 2007 included: a 72 GWh reduction in annual electricity usage; approximately $7.7 million in annual savings to customers; a 16 MW reduction in peak electricity demand; and a 50 thousand tonne reduction of GHGs. A business case was presented along with details of proposed residential, commercial and industrial programs. A cost benefit analysis was provided, as well as an outline of the plan's budget and organizational structure. It was concluded that the success of the various program elements will be based on quantitative and qualitative data on the actual effect on energy use of each customer sector, as well as its effect on system demand profiles. Data will be collected through the use of customer surveys, questionnaires, and direct feedback from partners, educators and manufactures and suppliers. 11 tabs., 16 figs

    Full Text Available Effective transboundary conservation of highly migratory marine animals requires international management cooperation as well as clear scientific information about habitat use by these species. Populations of leatherback turtles (Dermochelys coriacea in the eastern Pacific have declined by >90% during the past two decades, primarily due to unsustainable egg harvest and fisheries bycatch mortality. While research and conservation efforts on nesting beaches are ongoing, relatively little is known about this population of leatherbacks' oceanic habitat use and migration pathways. We present the largest multi-year (2004-2005, 2005-2006, and 2007 satellite tracking dataset (12,095 cumulative satellite tracking days collected for leatherback turtles. Forty-six females were electronically tagged during three field seasons at Playa Grande, Costa Rica, the largest extant nesting colony in the eastern Pacific. After completing nesting, the turtles headed southward, traversing the dynamic equatorial currents with rapid, directed movements. In contrast to the highly varied dispersal patterns seen in many other sea turtle populations, leatherbacks from Playa Grande traveled within a persistent migration corridor from Costa Rica, past the equator, and into the South Pacific Gyre, a vast, low-energy, low-productivity region. We describe the predictable effects of ocean currents on a leatherback migration corridor and characterize long-distance movements by the turtles in the eastern South Pacific. These data from high seas habitats will also elucidate potential areas for mitigating fisheries bycatch interactions. These findings directly inform existing multinational conservation frameworks and provide immediate regions in the migration corridor where conservation can be implemented. We identify high seas locations for focusing future conservation efforts within the leatherback dispersal zone in the South Pacific Gyre.

  16. The Butterfly House Industry: Conservation Risks and Education Opportunities

    Directory of Open Access Journals (Sweden)

    Michael Boppré

    2012-01-01

    Full Text Available This paper addresses the mass supply and use of butterflies for live exhibits, discusses the risks to biodiversity which this creates, and the educational opportunities it presents. Over the past 30 years a new type of insect zoo has become popular worldwide: the butterfly house. This has given rise to the global Butterfly House Industry (BHI based on the mass production of butterfly pupae as a cash crop. Production is largely carried out by privately-owned butterfly farms in tropical countries, notably Central America and Southeast Asia. Most pupae are exported to North America and Europe, although the number of butterfly houses in tropical countries is growing. The BHI is described with respect to its stakeholders, their diverse interests, and its extent. It is estimated that the global turnover of the BHI is in the order of USD 100 million. From a conservation perspective, there is a tension between risks and benefits. The risks to biodiversity are primarily unsustainable production, potential bastardisation of local faunas and floras, and genetic mixing within and even between butterfly species. This paper discusses general ways of managing these risks. Ethical concerns range from fair trade issues to animal husbandry and the use of wildlife for entertainment. For the risks to biodiversity and unresolved ethical issues to be tolerable, the BHI needs to make a significant contribution to conservation, primarily through effective education about butterfly biology as a means to raise public awareness of basic ecological processes, and conservation and environmental issues. It should also engage with local conservation initiatives. Currently the BHI′s great potential for public good in these respects is rarely realised. The paper concludes by looking at the special nature of the BHI, and its need for effective self-regulation if it is to continue to escape from public scrutiny and the introduction of restrictive regulations. The BHI needs to

    International Nuclear Information System (INIS)

    Sardianou, Eleni

    2007-01-01

    This paper develops an empirical model to investigate the main determinants of household energy conservation patterns in Greece employing cross-section data. In the empirical analysis, household energy-conserving choices models are employed, using a discrete and a latent trait variable respectively as a dependent variable. The results show that socio-economic variables such as consumers' income and family size are suitable to explain differences towards energy conservation preferences. In addition, the results suggest that electricity expenditures and age of the respondent are negatively associated with the number of energy-conserving actions that a consumer is willing to adopt. Finally, other variables such as environmental information feedback and consciousness of energy problems are characteristics of the energy-saver consumer. By evaluating consumer's decision-making process with regards to energy conservation measures, we are able to formulate and propose an effective energy conservation framework for Greece. An energy policy framework is among the main prerequisites not only to achieve sustainable development but also to maintain consumers' quality of life

    It is not incorrect to state that all major environmental problems, such as the greenhouse effect, destruction of the ozone layer from CFC`s, acid rain due to air pollution by NOx and SOx, etc., are caused by excessive industrial and residential energy consumption. Considering the finite world energy resources and limited global space, the day might be already upon us in which the total amount of energy consumption in the world should be reduced. To maintain a high living standard without increasing energy consumption, waste energy recovery and energy conservation are vitally important. In order to effective use of energy resources, we should really know the meaning of the energy consumption and the characteristics of energy resources. In this paper, the technological aspects of energy conservation are stated from the standpoint of available energy.

    The Department of Energy's (DOE) Office of Conservation and Renewable Energy proudly presents this summary of some its most successful projects and activities. The projects included in this document have made significant contributions to improving energy efficiency and fuel flexibility in the United States. The energy savings that can be realized from these projects are considerable. Americans have shown an impressive ability to reduce energy consumption since 1973. Studies show that 34 quadrillion Btus (quads) of energy were saved in 1988 alone as a result of energy conservation and other factors. These savings, worth approximately $180 billion, represent more energy than the United States obtains from any other single source. The availability of new, energy-efficient technologies has been an important ingredient in achieving these savings. Federal efforts to develop and commercialize energy-saving technologies and processes are a part of the reason for this progress. Over the past 10 years, DOE has carefully invested more than $2 billion in hundreds of research and development (R D) projects to ensure the availability of advanced technology in the marketplace. These energy-efficient projects are carried out through DOE's Office of Conservation and Renewable Energy and reflect opportunities in the three energy-consuming, end-use sectors of the economy: buildings, transportation, and industry.

    1993-01-01

    Italian energy conservation Law No. 9 was designed to reduce Italy's worrisome 82% dependency on foreign energy supplies by encouraging the development and use of renewable energy sources, fuel diversification and auto-production/cogeneration by private industry. Law No. 10 was intended to promote energy conservation initiatives especially with regard to the efficient use of energy for space heating in public buildings. Both of these legal incentives have encountered great difficulties in implementation due to the inability of the Government to provide the necessary timely and sufficient start-up funds, as well as, due to the excessive bureaucratism that was built into the administrative procedures

    International Nuclear Information System (INIS)

    Michna, J.; Bednarz, L.M.

    2004-01-01

    The paper presents extracts from an extended review devoted to recent changes and current trends in the national energy policy pursued in the USA. In 2001 the President Bush proposed an energy strategy for the period to 2025 that would promote energy conservation, repair and expand energy infrastructure, and increase energy supply while protecting the environment. The material stresses the importance of a sound national energy policy addressing supply, energy distribution and conservation. Well - illustrated data are given on the energy production and consumption (total, per capita, per $, by category, by fuel, etc.) and on the emissions (by sector, by fuel, by region, etc.). Giving an accurate account of the current situation with energy in America and a vision of its development for the first quarter of our century, these data are helpful for analyzing the national energy policies in other countries, post - transitional included.

    1992-01-01

    The decade and half since the oil crisis of 1973 has been a period that has witnessed a steady growth of the energy conservation ethos in India. Housekeeping and low risk conservation options have been largely preferred so far. The IMWG (Inter-Ministerial Working Group on Utilization and Conservation of Energy) study did not evaluate potential saving through the introduction of high risk and high pay-off technologies. The potential for energy conservation in India is substantial. However, some of the barriers to achieving the potential in the past have been energy prices which deviate from rational tariffs and prices, a lack of information on specific measures and of options for achieving energy conservation, paucity of capital for schemes requiring technology upgradation and efficiency improvements, and the inadequacy if institutional arrangement for promoting energy conservation in different sectors of the economy. Recent efforts pursued by several organizations however provide some basis for optimism. Given the growing capital intensity of the energy sector in India, more vigorous efforts are likely to be made in the future. In particular, success stories in some industrial units indicate that decentralized efforts by the units themselves can achieve a great deal in improving the efficiency of energy use, particularly in the Indian industry. Policies to promote such programmes would help accelerate energy conservation efforts in industrial units and in other sectors. It is therefore hoped that the intensity of energy use in several sectors of the indian economy will be reduced significantly in the coming years. (author). 3 refs., 3 tabs

    1982-11-01

    This report systematically compares, within a consistent framework, the technical and economic characteristics of energy-conserving irrigation systems with those of conventional irrigation systems and to determine total energy savings. Levelized annual costs of owning and operating both energy-conserving and conventional irrigation systems have been developed and compared for all 17 states to account for the differences in energy costs and irrigation conditions in each state. Market penetration of energy-conserving systems is assessed for those systems having lower levelized annual costs than conventional systems performing the same function. Annual energy savings were computed by matching the energy savings per system with an assumed maximum market penetration of 100 percent in those markets where the levelized annual costs of energy-conserving systems are lower than the levelized annual costs of conventional systems.

    2000-06-01

    In 1992 the Thai Government passed the Energy Conservation Promotion (ECP) Act to improve energy efficiency in Thai industry and commerce. The Thai-German Energy Efficiency Promotion Project (ENEP) is supporting the Department of Energy Development and Promotion (DEDP) in its effort to implement the Energy Conservation Program for large buildings and designated factories. About 4000 buildings and factories under the Compulsory Program, have to report every 6 months their energy consumption data to DEDP. Every 3 years energy audits have to be conducted by registered energy consultants, to identify energy saving opportunities, to set saving targets and to recommend energy conservation measures. Investments in energy efficient technologies are subsidized from an Energy Conservation Fund. Data from the energy consumption reports and the energy audit reports are collected in DEDP's database for further processing. The database is structured according to the Thai Standard Industrial Classification. In order to exploit the wealth of information provided by the auditing procedure the objective of the present work carried out by the consultant FhG-ISI for DEDP/BERC on behalf of the German Gesellschaft fuer Technische Zusammenarbeit (GTZ) was to recommend an appropriate set of energy efficiency indicators. This indicator set should allow DEDP to extract from the energy consumption reports, energy audit reports and other sources, useful statistical information to monitor and improve energy efficiency in Thailand.

    Time Warner Cable (TWC), now Charter Communications (CC), partnered with the National Renewable Energy Laboratory (NREL) to assess the technical and economic potential for solar photovoltaic (PV), wind, and ground-source heat-pump systems at 696 TWC facilities. NREL identified 306 sites where adding a renewable energy system would provide cost savings over the project life-cycle. In general, the top sites have some combination of high electricity rates ($0.16-$0.29/kWh), significant state incentives, and favorable net-metering policies. If all projects were implemented via third-party power purchase agreements, TWC/CC would save $37 million over 25 years and meet 10.5% of their energy consumption with renewable energy. This paper describes the portfolio screening methodology used to identify and prioritize renewable energy opportunities across the TWC sites, as well as a summary of the potential cost savings that may be realized by implementing these projects. This may provide a template for other companies interested in identifying and prioritizing renewable energy opportunities across a large number of geographically dispersed sites. Following this initial portfolio analysis, NREL will be conducting in-depth analysis of project development opportunities at ten sites and evaluating off-grid solutions that may enable carbon emission reduction and grid independence at select facilities.

  19. Energy efficiency opportunities in the brewery industry

    Worrell, Ernst; Galitsky, Christina; Martin, Nathan

    2002-06-28

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

    The United States (U.S.) Department of Energy (DOE) and the National Energy Technology Laboratory (NETL) are working in conjunction with the City of Pittsburgh (City) to transform how energy is produced, transported, and consumed in the City. This transformation will rely on 21st Century Energy Infrastructure designs, which leverage advanced technology and design techniques to modernize energy infrastructure, create new business models and markets, and expand technology research and development opportunities. Achieving this vision will require developing solutions that are unique to the City: its climate, topography, energy needs, resources, and existing infrastructure.a In this way, the City will demonstrate what the American “City of the Future” looks like, with all its attendant environmental, economic, and job-creation benefits. It will also serve as a template for other cities seeking to reinvent their energy systems.

    Ernest C. Baynard III, in the Foreword to the conference, told of the purpose of the conference - to compare and discuss the policies and laws that highly industrialized nations have used and considered to meet the challenge of energy conservation. The following countries participated in the conference: U.K.; Australia; Federal Republic of Germany; Japan; France; Canada; Sweden; Italy; the Netherlands; and the U.S. The IEA and the Commission of the European Communities also participated. The conference format consisted of ministerial addresses to the conference, interspersed with panel discussions focusing on energy conservation in transportation, industry, agriculture, and utilities; residential, commercial, and industrial buildings; and emergency situations. There was also a panel discussion on the role of government in energy conservation and energy information collection. The panels were composed of participating countries' representatives. (MCW)

    1989-04-01

    A number of impediments have discouraged federal agencies from using shared energy savings contracts. As of November 30, 1988, only two federal agencies - the U.S. Postal Service (USPS) and the Department of the Army -had awarded such contracts even though they can yield significant energy and cost savings. The three major impediments we identified were uncertainty about the applicability of a particular procurement policy and practice, lack of management incentives, and difficulty in measuring energy and cost savings. To address the first impediment, the Department of Energy (DOE) developed a manual on shared energy savings contracting. The second impediment was addressed when the 100th Congress authorized incentives for federal agencies to enter into shared savings contracts. DOE addressed the third impediment by developing a methodology for calculating energy consumption and cost savings. However, because of differing methodological preferences, this issue will need to be addressed on a contract-by-contract basis. Some state governments and private sector firms are using performance contracts to reduce energy costs in their buildings and facilities. We were able to identify six states that were using performance contracts. Five have established programs, and all six states have projects under contract. The seven energy service companies we contacted indicated interest in federal shared energy savings contracting

    The prices of fuels in the international markets affect the development of consumer prices of energy in Finland. In the near future no factors can be foreseen, which would cause major increases in the prices of oil, coal or gas. It can thus not be expected that increased fuel prices would motivate more efficient energy conservation. In international comparison, consumer prices of energy have been relatively low in Finland. This applies especially to electricity. After the removal of price controls, energy prices have been determined by the markets. The influence of the public authorities in energy pricing is put into effect through taxation. The price of energy has a fairly small effect on energy consumption in a short term, but longer term effects are more significant. Energy products are faxed in all western countries. (orig.)

  14. South Asia energy security: Challenges and opportunities

    International Nuclear Information System (INIS)

    Kumar Singh, Bhupendra

    2013-01-01

    South Asia has witnessed a growing imbalance between energy demand and its supply from indigenous sources resulting in increased import dependence. Energy endowments differ among the South Asian countries. However, access to the significant energy resources in the neighboring countries is denied, which increases the cost of energy supply and reduces energy security of the individual countries and of the region as a whole. The countries in the region could benefit significantly only by strengthening the mechanism of energy trade through improved connectivity. Therefore, greater cooperation within South Asia could be one of the most effective ways to deal with this Regional Energy deficit and ensure Energy Security of the Region. - Highlights: • No South Asian country is going to be able to meet its energy needs domestically. • Fostering cross border energy trade and promotion of investments opportunities are key solutions. • India’s neighbors have huge potential in hydroelectricity. • Co-operation among nations to tap the energy resource can be a win–win situation for all. • However it faces certain challenges

    2013-01-01

    The cement industry represents one of the most energy intensive sectors in Taiwan. Energy audits are the direct tools which are employed to help reduce energy consumption. The objectives of energy audits are to establish energy audit systems, provide on-site energy audit service and reduce production cost. This study summarized the energy savings implemented in Taiwan's cement industry; the data were obtained from the on-line Energy Declaration System in 2010. The total implemented energy savings amounted to 68,512 kilo liter of crude oil equivalent (KLOE). The energy audit group audited seven Taiwanese cement plants in 2011 and revealed an energy saving potential of 2571.6 MWh of electricity and 1002.8 KLOE of thermal energy. The total potential energy saving was 1708.5 KL of crude oil equivalent (KLOE), equivalent to a 4560 t reduction in CO 2 emissions, representing the annual CO 2 absorption capacity of a 122 ha forest plantation. - Highlights: • This study summarizes the energy savings implemented in Taiwan's cement industry from the on-line Energy Declaration System. • The energy audit group audited seven Taiwanese cement plants in 2011 and revealed energy saving potential was 1708.5 KLOE. • This work aims to examine what Taiwan has done and also describes the current status in cement industry. • In addition, some potential energy conservation opportunities or measures are revealed in this paper

    Major developments, as well as remaining challenges and the associated research opportunities, are evaluated for three technologically distinct approaches to solar energy utilization: solar electricity, solar thermal, and solar fuels technologies. Much progress has been made, but research opportunities are still present for all approaches. Both evolutionary and revolutionary technology development, involving foundational research, applied research, learning by doing, demonstration projects, and deployment at scale will be needed to continue this technology-innovation ecosystem. Most of the approaches still offer the potential to provide much higher efficiencies, much lower costs, improved scalability, and new functionality, relative to the embodiments of solar energy-conversion systems that have been developed to date.

    Energy-conservation activities require new functional and technical activities in all participating organizations and the prospects of effectively managing such activities are contingent upon the specific organizational setting. Based on a previous large-scale investigation in which we identified five organizational archetypes, in-depth longitudinal case studies were undertaken of five organizations in Sweden during 5 years, each organization representing a different archetype. The five organizations have distinct organizational prerequisites and separate basic motivations to engage and succeed in energy-conservation management. Implications for government policy and managerial action are discussed in detail. (author)

    Energy Technology Data Exchange (ETDEWEB)

    1978-04-01

    The Urban Land Institute (ULI) has prepared the following list of outstanding energy conserving projects for the US Department of Energy. As requested by the Department, the list includes descriptions of land developments and individual buildings suggested by members of ULI and by other sources. The projects have been selected to exemplify the major energy saving techniques in use today, with emphasis on those strategies most significant for people engaged in the business of land development. To make the list a useful reference for developers and public officials, ULI has attempted to cover energy conservation in the broadest sense from overall site planning to the functioning of individual building components. Focusing too closely on the myriad types of hardware available has been avoided and examples of the basic considerations important to energy-conscious planning and design are provided. Details on some heating, ventilation and air conditioning systems are provided in order to acquaint readers with major innovations in the field.

    1997-01-01

    Wind power is today a mature technology, which at windy locations, is economically competitive to conventional power generation technologies. This and growing global environmental concerns have led governments to encourage and plan for wind energy development, a typical aim being 10% of electricity...... consumption. The successful operation of the three major power systems of Cape Verde, with a total wind energy penetration of about 15% since December 1994, demonstrates that power systems can be operated with high penetration of wind energy by adding simple control and monitoring systems only. Thorough...... analyses conclude that expanding to even above 15% wind energy penetration in the Cape Verde power systems is economical. Worldwide, numerous locations with favorable wind conditions and power systems similar to the Capeverdean provide good opportunities for installing wind farms and achieving high wind...

    2012-01-01

    The food industry in Taiwan is labor intensive, the cost of raw materials is high, and there is much product diversification. Although this industry is primarily small and medium scale, it is a large user of electricity in Taiwan's manufacturing sector. The concentration of greenhouse gases (GHGs) from manufacturing activities and vehicle emissions has increased remarkably. Energy audits are a basic and direct means by which energy efficiency can be improved, energy consumption reduced, and carbon dioxide emissions inhibited. This work summarizes the energy saving potential of 76 firms and the energy savings implemented by 23 firms as determined by energy audit tracking and from the on-line energy declaration system in Taiwan's food industry. The results of this study can serve as a benchmark for developing a quantified list in terms of potential energy savings and opportunities for improving the efficiency of the food industry. - Highlights: ► This work summarizes the energy saving potential and the energy savings implemented in food industry. ► The results of this study can serve as a benchmark for developing a quantified list in terms of potential energy savings. ► The opportunities for improving the efficiency of the food industry can be a reference.

  17. CO2 reduction through energy conservation

    International Nuclear Information System (INIS)

    1991-05-01

    A study was carried out of the potential to economically reduce carbon dioxide emissions through energy conservation in the petroleum and natural gas industry. The study examined current and projected emissions levels, cogeneration at gas plants, flaring, economics, regulation, reporting requirements, implementation, and research and development. Economically attractive energy conservation measures can reduce oil and gas industry, exclusive of Athabasca oil sands operations, CO 2 emissions by 6-7%. The energy conservation options identified range from field energy awareness committees through to equipment retrofits and replacement. At ca 3 million tonnes/y, these reductions will not offset the increases in oil and gas related CO 2 emissions anticipated by producers and Alberta government agencies. There will be increasing emphasis on in-situ bitumen production, more energy intensive light crude oil production and increasing natural gas sales, increasing energy inputs in excess of reductions. Cogeneration of electricity for utility company distribution and for internally required steam at gas plants and in-situ production sites is not economic due to low electricity prices. 8 tabs

    Majority of the power generation in India is carried out by conventional energy sources, coal and fossil fuels being the primary ones, which contribute heavily to greenhouse gas emission and global warming. The Indian power sector is witnessing a revolution as excitement grips the nation about harnessing electricity from various renewable energy sources. Electricity generation from renewable sources is increasingly recognized to play an important role for the achievement of a variety of primary and secondary energy policy goals, such as improved diversity and security of energy supply, reduction of local pollutant and global greenhouse gas emissions, regional and rural development, and exploitation of opportunities for fostering social cohesion, value addition and employment generation at the local and regional level. This focuses the solution of the energy crisis on judicious utilization of abundant the renewable energy resources, such as biomass, solar, wind, geothermal and ocean tidal energy. This paper reviews the renewable energy scenario of India as well as extrapolates the future developments keeping in view the consumption, production and supply of power. Research, development, production and demonstration have been carried out enthusiastically in India to find a feasible solution to the perennial problem of power shortage for the past three decades. India has obtained application of a variety of renewable energy technologies for use in different sectors too. There are ample opportunities with favorable geology and geography with huge customer base and widening gap between demand and supply. Technological advancement, suitable regulatory policies, tax rebates, efficiency improvement in consequence to R&D efforts are the few pathways to energy and environment conservation and it will ensure that these large, clean resource bases are exploited as quickly and cost effectively as possible. This paper gives an overview of the potential renewable energy resources

  19. On energy conservation and energy research. Om energioekonomisering og energiforskning

    Energy Technology Data Exchange (ETDEWEB)

    1989-01-01

    This report to the Storting (Parliament) is the third one on energy conservation during the last 10 years. As earlier, the report mainly treats the use of energy for stationary objects. The background for this report is, above all, the increased environmental requirements to the energy policy attached to the use of fossil fuels. The economic energy conservation potential of Norway is estimated on the basis of the present energy prices and available technology. For stationary energy use it amounts to ca 23 TWh, of which 16 TWh refer to electric power and 7 TWh to oil. Among the measures of the authorities to realize this potential, information about energy economy and energy technology is one of the most important. Other important measures are research and development activities as well as temporary arrangements for economic support. Energy conservation efforts, and efforts for a better environment should often be considered together, because higher energy efficiency in general can result in important positive environmental impacts. In the long term, the global enviromental problems may be the strongest motive power for an increased effort in energy conservation. 38 figs., 22 tabs.

  20. Ecosystem services and opportunity costs shift spatial priorities for conserving forest biodiversity.

    Directory of Open Access Journals (Sweden)

    Matthias Schröter

    Full Text Available Inclusion of spatially explicit information on ecosystem services in conservation planning is a fairly new practice. This study analyses how the incorporation of ecosystem services as conservation features can affect conservation of forest biodiversity and how different opportunity cost constraints can change spatial priorities for conservation. We created spatially explicit cost-effective conservation scenarios for 59 forest biodiversity features and five ecosystem services in the county of Telemark (Norway with the help of the heuristic optimisation planning software, Marxan with Zones. We combined a mix of conservation instruments where forestry is either completely (non-use zone or partially restricted (partial use zone. Opportunity costs were measured in terms of foregone timber harvest, an important provisioning service in Telemark. Including a number of ecosystem services shifted priority conservation sites compared to a case where only biodiversity was considered, and increased the area of both the partial (+36.2% and the non-use zone (+3.2%. Furthermore, opportunity costs increased (+6.6%, which suggests that ecosystem services may not be a side-benefit of biodiversity conservation in this area. Opportunity cost levels were systematically changed to analyse their effect on spatial conservation priorities. Conservation of biodiversity and ecosystem services trades off against timber harvest. Currently designated nature reserves and landscape protection areas achieve a very low proportion (9.1% of the conservation targets we set in our scenario, which illustrates the high importance given to timber production at present. A trade-off curve indicated that large marginal increases in conservation target achievement are possible when the budget for conservation is increased. Forty percent of the maximum hypothetical opportunity costs would yield an average conservation target achievement of 79%.

    A voluntary industrial energy-conservation program was initiated and now includes 50 trade organizations representing over 3,000 companies. Their current reporting system is an effort to respond to the Energy Policy and Conservation Act requirements, as now modified by the National Energy Conservation Policy Act. DOE's Office of Industrial Programs held six workshops in various key locations between November 1978 and February 1979 to enable energy managers to develop ideas and make suggestions that would improve the current and future energy-reporting programs. This report is a summary of the wide range of recommendations that the workshop participants offered as a means of meeting the NECPA requirements and the criticism of the current reporting program. It also reflects industry's views on potential approaches to future reporting. (MCW)

    Compressed air is an essential utility that accounts for a substantial part of the electricity consumption (bill) in most industrial plants. Although the general saying Air is free of charge is not true for compressed air, the utility's cost is not accorded the rightful importance due to its by most industries. The paper will show that the cost of 1 unit of energy in the form of compressed air is at least 5 times the cost electricity (energy input) required to produce it. The paper will also provide energy conservation tips in compressed air systems

    Energy conservation is becoming an increasingly important instrument to stay competitive in today is increasingly global market. Important investments have been made in infrastructure and personnel in order to improve the management of energy such as increased metering, energy dashboards, energy managers, etc. Despite these investments, the results have not materialized and there is still a significant potential to further reduce energy consumption. In this paper a new methodology will be presented that helps industry better operate existing assets in order to reduce energy consumption, without having to make capital investments. The methodology uses a combination of advanced data analysis tools and a specific implementation scheme that has lead to significant savings in industry. The advanced data analysis tools are used to analyze the variability of the process in order to assess when the plant has been operated well or not so well in the past. By finding the root causes of these variations and the key variables that can explain them, improved operating guidelines and models can be developed and implemented. The specific implementation scheme is an important part of the methodology as it involves the people operating the plant. Several user cases will be presented showing an energy conservation of between 10%-20% without capital investments necessary. (author)

    The dwindling wildlife species of our planet have become a cause célèbre for conservation groups, governments, and concerned citizens throughout the world. The application of powerful new genetic technologies to surviving populations of threatened mammals has revolutionized our ability to recognize hidden perils that afflict them. We have learned new lessons of survival, adaptation, and evolution from viewing the natural history of genomes in hundreds of detailed studies. A single case history of one species, the African cheetah, Acinonyx jubatus, is here reviewed to reveal a long-term story of conservation challenges and action informed by genetic discoveries and insights. A synthesis of 3 decades of data, interpretation, and controversy, capped by whole genome sequence analysis of cheetahs, provides a compelling tale of conservation relevance and action to protect this species and other threatened wildlife. © The American Genetic Association 2017.

    Over the past 50 years, human agents of deforestation have changed in ways that have potentially important implications for conservation efforts. We characterized these changes through a meta-analysis of case studies of land-cover change in the tropics. From the 1960s to the 1980s, small-scale farmers, with state assistance, deforested large areas of tropical forest in Southeast Asia and Latin America. As globalization and urbanization increased during the 1980s, the agents of deforestation changed in two important parts of the tropical biome, the lowland rainforests in Brazil and Indonesia. Well-capitalized ranchers, farmers, and loggers producing for consumers in distant markets became more prominent in these places and this globalization weakened the historically strong relationship between local population growth and forest cover. At the same time, forests have begun to regrow in some tropical uplands. These changing circumstances, we believe, suggest two new and differing strategies for biodiversity conservation in the tropics, one focused on conserving uplands and the other on promoting environmental stewardship in lowlands and other areas conducive to industrial agriculture.

  1. Pollution prevention and energy conservation: Understanding the interactions

    International Nuclear Information System (INIS)

    Purcell, A.H.

    1992-01-01

    The traditional view holds that pollution prevention is good for energy conservation and vice versa. Analysis of pollution prevention and energy conservation activities indicates, however, that interactions and synergies between environmental and energy factors can mean that pollution prevention can be energy intensive and, conversely, that energy conservation can lead to increased pollution. Full cost accounting, taking into account all media, must be performed before precise pollution prevention-energy conservation interrelationships can be characterized and quantified. Use of a pollution prevention-energy conservation matrix can further this understanding

    The objective of this document is to present, in a clear and concrete way, the results presented in the book -Nuclear energy an opportunity for Mexico- this book was prepared to evaluate the feasibility of constructing a new nuclear power plant in Mexico considering the evident worldwide rise of the nuclear energy as a way to produce electricity. The worldwide nuclear power renaissance is based on several factors, some of the most important are the uncertainty about the availability and behavior of fossil fuels, the impacts of the green house gases over the environment; improvements in the design and construction process that allow to reduce the construction periods; the competitiveness of nuclear power with other clean technologies and the experience of the nuclear power plant fleet that has shown performance indicators that exceed other technologies. Also, the competitiveness of the nuclear power as base load to satisfy the electricity demand. This book include the actual situation of the nuclear power in the world and the challenges and opportunities to incorporate additional nuclear power plants in Mexico, with the aim of satisfy the future electricity demand, in harmony with the environment and in a secure and safety way. Nonetheless, by itself a nuclear power plant is not the entire or only solution for the environmental and security of supply issues, but nuclear power is a main part of the integral solution where renewable and new clean technologies (e.g. carbon capture and storage and integrated gasification combined cycle) plays an important role. Nowadays, several countries go forward for the use or nuclear power, reinforcing and in some cases restarting their nuclear power programs, Mexico should not be the exception, nuclear power deserves to be included in the portfolio of generation technologies in the future years. The main advantages of nuclear power, as well as the most questionable issues are deeply discussed in the book. (Author)

    1981-07-01

    The need to conserve energy has changed architecture, which now has distinct energy-conscious designs and a new design vocabulary. Future designs will consider how energy affects buildings and minimize the impact in siting and landscaping decisions. Existing buildings must also be accommodated. No building performance standards exist yet that allow architects to be creative, although architects are working more closely with engineers and builders. Earth-sheltering designs will have to overcome psychological barriers, but the opportunities to preserve open space and views will improve their acceptability. The American Institute of Archiects will assume leadership in this area, but it will not take over all the research programs abandoned by the Reagan administration. Future housing will be more compact, grouped, and closely integrated. (DCK)

    The report describes the completed survey and the methodology used for the analysis of energy saving opportunities and potentials for processing technologies and equipment in the industry. The report also includes a total of fourteen technology descriptions, of which eleven relate to end use of energy, while the three descriptions are for cross-technologies. The technology descriptions analyse any significant savings opportunities in the processing technologies concerned and work out the potentials of 'here and now' cost savings, with 2, 4 and 10-year payback time, respectively. The survey makes it possible to prioritize the instruments with the shortest payback times. The total savings potential for the eleven end-use technologies is estimated to be 10% at 2 years of payback time, 15% at four year payback time, and 32% at the 10 year payback time. The percentage potential is somewhat greater for the end-use technologies using electricity than the end-use which mainly uses fuel. That the potential is less for fuel-based end-use technologies may be explained by the fact that they are key processes that are regularly upgraded to increase product quality, to reduce production time and waste, etc. Such improvements also help to save energy and means that further improvements are relatively expensive.

    Tribology is the study of friction, wear and lubrication. Recently, the concept of “green tribology” as “the science and technology of the tribological aspects of ecological balance and of environmental and biological impacts” was introduced. The field of green tribology includes tribological technology that mimics living nature (biomimetic surfaces) and thus is expected to be environmentally friendly, the control of friction and wear that is of importance for energy conservation and conversion, environmental aspects of lubrication and surface modification techniques, and tribological aspects of green applications such as wind-power turbines or solar panels. This book is the first comprehensive volume on green tribology. The chapters are prepared by leading experts in their fields and cover such topics as biomimetics, environmentally friendly lubrication, tribology of wind turbines and renewable sources of energy, and ecological impact of new technologies of surface treatment.

  8. Local policies for DSM: the UK's home energy conservation act

    Jones, E.; Leach, M.

    2000-01-01

    Residential energy use accounts for approximately 28 per cent of total primary energy use in the UK, with consumption in this sector forecast to increase due partly to expanding numbers of households. Finding ways to reduce residential energy consumption must form a key part of the climate change strategies of the UK and all developed countries. In 1995, an innovative piece of legislation was passed in the UK, devolving residential energy efficiency responsibility to local government. Under 'The Home Energy Conservation Act' (HECA), local authorities are obliged to consider the energy efficiency of private as well as public housing stock. Authorities were given a duty to produce a strategy for improving residential energy efficiency in their area by 30 per cent in the next 10-15 years. This paper describes the enormous variation in the quality of local authorities' strategies and discusses reasons for this variation. Based on a nationwide survey of HECA lead officers, it considers the opportunities and constraints facing local authorities, and what has been achieved to-date under the Act. It also examines how HECA fits into the UK's national energy policy and explains the roles of other institutions across the public, private and voluntary sector in facilitating implementation of the Act. Finally, the paper considers how other countries can learn from the UK's HECA experience and can use the Act as a template to apply the principle of subsidiarity to this area of environmental policy.

  9. Electrorheology for energy production and conservation

    Science.gov (United States)

    Huang, Ke

    Recently, based on the physics of viscosity, we developed a new technology, which utilizes electric or magnetic fields to change the rheology of complex fluids to reduce the viscosity, while keeping the temperature unchanged. The method is universal and applicable to all complex fluids with suspended particles of nano-meter, submicrometer, or micrometer size. Completely different from the traditional viscosity reduction method, raising the temperature, this technology is energy-efficient, as it only requires small amount of energy to aggregate the suspended particles. In this thesis, we will first discuss this new technology in detail, both in theory and practice. Then, we will report applications of our technology to energy science research. Presently, 80% of all energy sources are liquid fuels. The viscosity of liquid fuels plays an important role in energy production and energy conservation. With an electric field, we can reduce the viscosity of asphalt-based crude oil. This is important and useful for heavy crude oil and off-shore crude oil production and transportation. Especially, since there is no practical way to raise the temperature of crude oil inside the deepwater pipelines, our technology may play a key role in future off-shore crude oil production. Electrorehology can also be used to reduce the viscosity of refinery fuels, such as diesel fuel and gasoline. When we apply this technology to fuel injection, the fuel droplets in the fuel atomization become smaller, leading to faster combustion in the engine chambers. As the fuel efficiency of internal combustion engines depends on the combustion speed and timing, the fast combustion produces much higher fuel efficiency. Therefore, adding our technology on existing engines improves the engine efficiency significantly. A theoretical model for the engine combustion, which explains how fast combustion improves the engine efficiency, is also presented in the thesis. As energy is the key to our national

    Vickers, V. T.

    1977-10-15

    During the past two decades the dairy industry has increased the efficiency of fuel utilization in the manufacture of all dairy products. The increased thermal efficiency is due to the greater use of hot water heating in milk treatment stations, the operation of larger capacity butter and cheese factories with increased factory mechanization, greatly improved processing plant design in milk powder and casein factories, and the increased use of oil and gas firing, together with more efficient automatic boiler plants. In the industry, a greater decrease in energy consumption would be possible through the greater availability of natural gas. Natural gas-fired turbines and/or reciprocating engines could be used for on-site power generation using the waste heat for processing purposes.

    Energy use per square foot from science research labs is disproportionately higher than that of other rooms in buildings on campuses across the nation. This is partly due to labs’ use of energy intensive equipment. However, laboratory management and personnel behavior may be significant contributing factors to energy consumption. Despite an apparent increasing need for energy conservation in science labs, a systematic investigation of avenues promoting energy conservation behavior in such labs appears absent in scholarly literature. This paper reports the findings of a recent study into the energy conservation knowledge, attitude and behavior of principle investigators, laboratory managers, and student lab workers at a tier 1 research university. The study investigates potential barriers as well as promising avenues to reducing energy consumption in science laboratories. The findings revealed: (1) an apparent lack of information about options for energy conservation in science labs, (2) existing operational barriers, (3) economic issues as barriers/motivators of energy conservation and (4) a widespread notion that cutting edge science may be compromised by energy conservation initiatives. - Highlights: ► Effective energy conservation and efficiency depend on social systems and human behaviors. ► Science laboratories use more energy per square foot than any other academic and research spaces. ► Time, money, quality control, and convenience overshadow personnel’s desire to save energy. ► Ignorance of conservation practices is a barrier to energy conservation in labs.

  15. Energy conservation on Nova Scotia farms: Baseline energy data

    2008-01-01

    Direct energy use is a small but essential component of the farm greenhouse gas (GHG) budget. Improvements in energy efficiency and renewable energy can help reduce farm operating costs, improve air quality and reduce GHG emission levels. Energy conservation is especially important in Nova Scotia (NS), Canada, where fossil fuels, particularly coal, remain the primary source of electrical generation. Responses from mail surveys were used to establish baseline data on a cross-section of NS farms with respect to direct energy costs and usage to demonstrate differences in farm type and size. A 32% (N=224) response rate was achieved. Based on this survey, the average energy bill for a NS farm in 2004 was $11,228, with most (61.7%) of their energy cost attributable to the purchase of petroleum products. Almost all farmers (96.4%) indicated that their energy cost was a primary concern. Farmers identified the operation of vehicles and mobile equipment, as well as lighting and heating as having the greatest energy requirements in their operations. Energy usage varied with farm type and size. NS farms consumed 1.2 petajoules of energy equivalent to 127 kilotonnes of CO 2 with 52.7% of emissions from electricity use in 2004

    1990-01-01

    This paper reports on a Denver Support Office project to evaluate cost estimation in the Institutional Conservation Program. Unit cost characteristics and cost prediction accuracy were evaluated from 1,721 Energy Conservation Measures (ECMs) and 390 Technical Assistance (TA) reports funded in the last six years. This information is especially useful to state and DOE review engineers in determining the reasonableness of future cost estimates. The estimated cost provisions for TA report grants were generally adequate to cover the actual costs. Individually, there was a tendency for TA reports to cost less than estimated by about 10%. TA report unit costs averaged $.09 to $.11 per square foot, and decreased as the building size increased. Individually, there was a tendency for ECMs to cost more than estimated by about 17%. Overall, the estimated costs of the 1,721 measures were $20.4 minion, while the actual costs were $21.4 million. This 4.6% difference indicates that, overall, ECM cost estimates have provided a reasonable basis for grant awards. There was a high variation in ECM unit costs. The data did not support speculation that there is a tendency to manipulate cost estimates to fit ECMs within the simple payback eligibility criteria of 2 to 10 years

    1980-03-15

    While studies of the past indicated a tight coupling of energy consumption and GNP, longer range indications are that they can be mutually decoupled. Developing nations can move forward towards achieving significant energy savings in their economics without fear of economic stagnation. Conservation policies at the national level are difficult to enunciate and the implementation mechanisms have to be strengthened. Macro-level economics may not be easily apparent as unit level economics. If energy conservation is not practiced, we would require the development of additional energy supply capacity with all of its economic implications. The role of science and technology inputs in industrial processes for minimizing energy consumption is significant. Sufficient funds should be allocated for pursuance of R and D activities in energy conservation and in developing alternative energy resources to supplement and later replace the existing costly transient fuels. A climate to promote conservation of energy should formulate policies which lays emphasis on energy conservation strategies rather than soley on energy growth issues. The effort should be directed towards energy programs that are a judicious mix up of energy and energy conservation strategies for achieving economic growth and a reasonable standard of living commensurate with the aspirations of the people. In capital-scarce economies, an account of the fact that energy conservation requires far less investment than energy capital supplies, conservation policies must play a central role in the overall framework of developing nation's national energy policies.

    Berger, Joel; Beckmann, Jon P

    2010-06-01

    In the United States, as elsewhere, a growing debate pits national energy policy and homeland security against biological conservation. In rural communities the extraction of fossil fuels is often encouraged because of the employment opportunities it offers, although the concomitant itinerant workforce is often associated with increased wildlife poaching. We explored possible positive and negative factors associated with energy extraction in the Greater Yellowstone Ecosystem (GYE), an area known for its national parks, intact biological diversity, and some of the New World's longest terrestrial migrations. Specifically, we asked whether counties with different economies-recreation (ski), agrarian (ranching or farming), and energy extractive (petroleum)-differed in healthcare (gauged by the abundance of hospital beds) and in the frequency of sexual predators. The absolute and relative frequency of registered sex offenders grew approximately two to three times faster in areas reliant on energy extraction. Healthcare among counties did not differ. The strong conflation of community dishevel, as reflected by in-migrant sexual predators, and ecological decay in Greater Yellowstone is consistent with patterns seen in similar systems from Ecuador to northern Canada, where social and environmental disarray exist around energy boomtowns. In our case, that groups (albeit with different aims) mobilized campaigns to help maintain the quality of rural livelihoods by protecting open space is a positive sign that conservation can matter, especially in the face of rampant and poorly executed energy extraction projects. Our findings further suggest that the public and industry need stronger regulatory action to instill greater vigilance when and where social factors and land conversion impact biological systems.

    Heavy water plant at Manuguru is designed to produce 185 MTY of NG heavy water based on bi-thermal H 2 S-H 2 O exchange process. Being a plant based on isotopic separation process, the requirement of feed water, utilities and the inventory of H 2 S is very huge. Sustained efforts have brought down the specific energy consumption from 53.3 GJ/Kg of nuclear grade product in the financial year 1997-98 to a value of 37.6 GJ/Kg of product in the financial year 2001-02, which amounts to a reduction of 29.5%. Several modifications have been done in the following areas, which contributed towards significant energy conservation eg. reduction in consumption of steam, electric power, chemicals and man hours and in the down time of the plant/equipment's, reduction in the loss of H 2 S, D 2 O and various utilities, enhanced recycling of liquid effluents, increase in production, on stream hours, purity of the inputs, avoiding trips and unusual occurrences, trimming the built in cushions, changes in the design/elimination of certain design provisions resulting in savings, increase in operational flexibility to facilitate smooth operation, improved house keeping and quality management, improved O and M practices, upgradation of required skills/qualifications of the personnel and increasing their motivation. This paper highlights the improvements done/being taken up since the year 2000. (author)

    Energy consumption in the residential sector offers an important opportunity for conserving resources. However, much of the current debate regarding energy efficiency in the housing market focuses on the physical and technical determinants of energy consumption, neglecting the role of the economic behavior of resident households. In this paper, we analyze the extent to which the use of gas and electricity is determined by the technical specifications of the dwelling as compared to the demographic characteristics of the occupying household, using a unique set of microeconomic data for a sample of more than 300,000 Dutch homes. The results show that residential gas consumption is determined principally by structural dwelling characteristics, such as the vintage, building type and quality of the home, while electricity consumption varies more directly with household composition, in particular income and family composition. Combining these results with projections on future economic and demographic trends, we find that, absent price increases for residential energy, the aging of the population and their increasing wealth will mostly offset improvements in the energy efficiency of the building stock resulting from policy interventions and natural revitalization.

    On request of the Dutch ministry of Economic Affairs five institutes have collaborated to create a 'Protocol Monitoring Energy Conservation', a common method and database to calculate the amount of energy savings realised in past years. The institutes concerned are the Central Bureau of Statistics (CBS), the Netherlands Bureau for Economic Policy Analysis (CPB), the Energy research Centre of the Netherlands (ECN), the National Agency for Energy and Environment (Novem) and the Netherlands Institute of Public Health and the Environment (RIVM). The institutes have agreed upon a clear definition of energy use and energy savings. The demarcation with renewable energy, the saving effects of substitution between energy carriers and the role of import and export of energy have been elaborated. A decomposition method is used to split up the observed change in energy use in a number of effects, on a national and sectoral level. This method includes an analysis of growth effects, effects of structural changes in production and consumption activities and savings on end use or with more efficient conversion processes. To calculate these effects the total energy use is desegregated as much as possible. For each segment a reference energy use is calculated according to the trend in a variable which is supposed to be representative for the use without savings. The difference with the actual energy use is taken as the savings realised. Results are given for the sectors households, industry, agriculture, services and government, transportation and the energy sector; as well as a national figure. A special feature of the protocol method is the application of primary energy use figures in the determination of savings for end users. This means that the use of each energy carrier is increased with a certain amount, according to the conversion losses caused elsewhere in the energy system. The losses concern the base year energy sector and losses abroad for imports of secondary

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

    Gupta, R.V.; Venugopal, M.

    1997-01-01

    The importance of conservation of energy is well recognised all over the world as the world reserves of fossil fuels will eventually run out depending on the rate of their use. This paper deals with various energy conservation schemes adopted at Heavy Water Plant, Manuguru (HWPM). Most energy conservation measures offer large financial saving with very short pay back periods. This fact has been well recognised by the management of HWPM as well as Heavy Water Board and their wholehearted and enthusiastic approach to energy conservation and energy management yielded very good results in reducing the operating cost. The process of energy conservation is not a one time exercise. Persistent efforts are on to identify the areas like condition of heat exchangers, margins in control valves, steam and condensate leakages etc. for further reduction in energy consumption

    Conservation of energy is a national agenda as had been set by our Prime Minister at various fora, in the case of coal mining also there is ample scope to reduce specific energy conservation. The issue can be resolved through 'energy audit' so as to identify the areas of improvement, technology to introduce and innovative system to adopt. In a nutshell it can be concluded that, through energy audit, we can immediately save 10-15 % of energy without any major investment

  17. Energy conservation and the principle of equivalence

    International Nuclear Information System (INIS)

    Haugan, M.P.

    1979-01-01

    If the equivalence principle is violated, then observers performing local experiments can detect effects due to their position in an external gravitational environment (preferred-location effects) or can detect effects due to their velocity through some preferred frame (preferred frame effects). We show that the principle of energy conservation implies a quantitative connection between such effects and structure-dependence of the gravitational acceleration of test bodies (violation of the Weak Equivalence Principle). We analyze this connection within a general theoretical framework that encompasses both non-gravitational local experiments and test bodies as well as gravitational experiments and test bodies, and we use it to discuss specific experimental tests of the equivalence principle, including non-gravitational tests such as gravitational redshift experiments, Eoetvoes experiments, the Hughes-Drever experiment, and the Turner-Hill experiment, and gravitational tests such as the lunar-laser-ranging ''Eoetvoes'' experiment, and measurements of anisotropies and variations in the gravitational constant. This framework is illustrated by analyses within two theoretical formalisms for studying gravitational theories: the PPN formalism, which deals with the motion of gravitating bodies within metric theories of gravity, and the THepsilonμ formalism that deals with the motion of charged particles within all metric theories and a broad class of non-metric theories of gravity

    Boer, J. de; Ester, P.; Mindell, C.; Schopman, M.

    1983-01-01

    This report presents an overview of consumer energy conservation policies and programs in the Netherlands and analyses them in terms of program objectives, conservation strategies, program instruments, context elements, and impacts on energy consumption, on consumers' lifestyles and on the environment. Part 1 briefly outlines the energy situation in the Netherlands. Diversification of energy sources and conservation of energy use are the main themes of Dutch energy policy. Controversial issues are the export volume of natural gas and the acceptability of nuclear energy. Part 2 describes and evaluates a number of consumer energy conservation programs. A broad range of programs is presented, including governmental programs (mass media compaigns, the national insulation program), initiatives from consumer organizations and environmental groups, as well as projects on the community level. Part 3 summarizes the main findings and suggests some policy recommendations. The climate of opinion in the Netherlands appears to be quite favorable towards energy conservation. The commitment to conserve, however, is not very strong. Given the broad variety of conservation programs the necessity of coordination is emphasized. As consumers tend to be weakly represented in the program agencies, it is recommended to extend or introduce their participation. Particular attention is given to the lack of evaluation studies. Usually, program impacts are unknown. The desirability of utilizing community level indicators in the assessment of energy conservation policy is underlined. (orig.)

    1996-07-01

    This report contains information for US DOE to use in making a determination on proposing energy conservation standards for distribution transformers as required by the Energy Policy Act of 1992. Potential for saving energy with more efficient liquid-immersed and dry-type distribution transformers could be significant because these transformers account for an estimated 140 billion kWh of the annual energy lost in the delivery of electricity. Objective was to determine whether energy conservation standards for distribution transformers would have the potential for significant energy savings, be technically feasible, and be economically justified from a national perspective. It was found that energy conservation for distribution transformers would be technically and economically feasible. Based on the energy conservation options analyzed, 3.6-13.7 quads of energy could be saved from 2000 to 2030.

    About 12 % of generated electric power is the nuclear power in Eastern European countries. Generally electric power is short in these countries, and as the countermeasures for environment, the promotion of nuclear power generation is considered. However, the public opinion opposing it is also strong. The situation in respective countries is briefly discussed. The prevention of warming of the earth and the reduction of carbon dioxide gas release are the largest environmental problems discussed in western countries, but in Eastern European countries, the far more primitive problem of the damage due to SO 2 is serious. Notwithstanding high sulfur brown coal is the main fuel, the installation of desulfurizing facilities has been neglected. The demand for the countermeasures to environmental pollution by people has become strong. The energy efficiency in Eastern European countries is poor, and it is one of the causes of environmental pollution. The industrial structure is centering around heavy industries which consume much energy, the energy loss arises due to the delay of equipment modernization, and the energy is cheap, so its saving is neglected. Energy conservation is important. (K.I.)

  8. Energy conservation and efficiency in manufacturing: Employee decisions and actions

    Science.gov (United States)

    Corson, Marla D.

    Energy conservation and intensity reduction efforts are becoming increasingly more prevalent and ultimately necessary, especially for energy-intensive manufacturing companies in particular to stay in business. Typical actions are to change technology, and thus, realize an energy cost savings in overall utilities. However, in today's competitive market, with climate change and other environmental impacts as well, it is necessary for the cost of energy to be valued as a cost of making a product, and thus, managed at the same level as the cost of labor or materials. This research assessed human behavior at the individual and organizational levels both at work and at home that either prompted or prohibited employees from taking daily action to conserve energy or develop greater energy efficient practices. Ultimately, the questions began with questions regarding employee views and knowledge of energy at work and at home and what drives both behaviors toward conservation or efficiency. And, the contribution identifies the key drivers, barriers, and/or incentives that affect those behaviors. The results of this study show that the key driver and motivator for energy conservation both at home and work is cost savings. The study showed that to further motivate individuals to conserve energy at home and work, more knowledge of the impact their actions have or could have as well as tools would be needed. The most poinient aspect of the research was the level of importance placed on energy conservation and the desire to conserve. The feedback given to the open ended questions was quite impressive regarding what employees have done and continue to do particularly within their homes to conserve energy. These findings brought about final recommendations that were in fact not expected but could significantly influence an increase in energy conservation at work by leveraging the existing desire to conserve which is a key component to decision making.

    Most of the countries around the world have realized that the key to attaining and maintaining prosperity and sovereignty is having independence and self-reliance in access to and subsequent use of energy. To address the global challenges, the energy system needs to undergo a transformation from fossil-fuels to renewable energy and energy efficient technologies. Pakistan has a huge potential for harnessing renewable energy and its share in the electricity mix has to be increased to achieve energy security. Security issues and circular debt in the country are the key challenges that need to be addressed to promote on-grid renewable energy through private sector. Around 38 % of the total Pakistani population remains without access to electricity. Fifty four per cent of the rural population currently has no access to electricity, forcing them to live a sub-standard life of poverty and social inequity. Microfinance and other innovative financial tools need to be evolved to promote rural electrification through renewable energies. (author)

    In some industries, most notably food and drink and chemicals, refrigeration accounts for a significant proportion of overall site energy costs. For instance, in the industrial handling of meat, poultry and fish, it often accounts for 50% of total energy costs. In ice-cream production the proportion is 70%. In a number of commercial sectors, refrigeration also represents a significant proportion of overall energy costs. For example: Cold storage 90%; Food supermarkets 50%; Small shops with refrigerated cabinets 70% or over; Pubs and clubs 30%. Against these high costs, even a small reduction in refrigeration energy use can offer significant cost savings, resulting in increased profits. Energy saving need not be expensive. Energy savings of up to 20% can be realised in many refrigeration plant through actions that require little or no investment. In addition, improving the efficiency and reducing the load on a refrigeration plant can improve reliability and reduce the likelihood of a breakdown. Most organisations can save energy and money on refrigeration by: More efficient equipment; Good maintenance; Housekeeping and control. This publication provides an understanding of the operation of refrigeration systems, identifies where savings can be realised and will enable readers to present an informed case on energy savings to key decision makers within their organisation.

    The propose of this paper is to explicate its title through investigating the different available thermal insulating materials and the various techniques of application, as practiced in Jordan, in particular, and as practiced in many parts of the world in general, which will satisfy Jordanian standards in terms of heat transmittance and thermal comfort. A brief comparison with international standards will shed some light on the stringent measures enforced in the developed world and on our striving aspirations to keep pace. The paper consists of four main parts, pseudoally divided. The first part will deal with the mechanism of heat loss and heat gain in structures during summer and winter. It will also explain the Time-lag phenomenon which is vital for providing thermal comfort inside the dwellings. The second part will evaluate the damages induced by the temperature gradients on the different elements of the structure, particularly next to exterior opening. The paper will also demonstrate the damages induced by water condensation and fungus growth on the internal surfaces of the structure and within its skeleton. A correlation between condensation and thermal insulation will be established. The third part of the paper will evaluate the different available thermal insulating materials and the application techniques which will satisfy the needs for thermal insulating and thermal comfort at the least cost possible. The criteria of an economical design shall be established. As a conclusion, the paper infers answers to the following different criteria discussed throughout the different parts of the paper. The main theme of questions can be summarized as follows: 1)How energy conservation is possible due to thermal insulation? 2)The feasibility of investing in thermal insulation? 3)Is thermal comfort and a healthy atmosphere possible inside the dwellings during all season! What are the conditions necessary to sustain them? 4)What environmental impacts can exist due to

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

    1993-01-01

    World fossil fuel reserves, historical and current rates of consumption are reviewed and estimates of indigeneous lives in geographical regions are made. Rates of production and accumulations of carbon dioxide and other greenhouse gases in the atmosphere are calculated and correlations made with measured global mean temperatures and concomitant sea-level rises. It is concluded that, if present rates of global fossil-fuel consumptions continue unabated, the world's fossil-fuel store will be depleted by the year 2050. This would be accompanied by a substantial rise in global mean temperature. The effects of various protocols for the reductions of emissions are examined. It is concluded that there is no alternative than to cease the production and release into the atmosphere of the more damaging man-made greenhouse gases as soon as is practicably possible and to seek a sustained reduction in the rates of combustion of fossil fuels world-wide via energy management and conservation.

    Guidance is given on measuring energy consumption in the plant and pinpointing areas where energy-conservation activities can return the most favorable economics. General energy-conservation techniques applicable to most or all segments of the dairy processing industry, including the fluid milk segment, are emphasized. These general techniques include waste heat recovery, improvements in electric motor efficiency, added insulation, refrigeration improvements, upgrading of evaporators, and increases in boiler efficiency. Specific examples are given in which these techniques are applied to dairy processing plants. The potential for energy savings by cogeneration of process steam and electricity in the dairy industry is also discussed. Process changes primarily applicable to specific milk products which have resulted in significant energy cost savings at some facilities or which promise significant contributions in the future are examined. A summary checklist of plant housekeeping measures for energy conservation and guidelines for economic evaluation of conservation alternatives are provided. (MHR)

    Since Taiwan lacks sufficient self-produced energy, increasing energy efficiency and energy savings are essential aspects of Taiwan's energy policy. This work summarizes the energy savings implemented by 303 firms in Taiwan's textile industry from the on-line Energy Declaration System in 2008. It was found that the total implemented energy savings amounted to 46,074 ton of oil equivalent (TOE). The energy saving was equivalent to 94,614 MWh of electricity, 23,686 kl of fuel oil and 4887 ton of fuel coal. It represented a potential reduction of 143,669 ton in carbon dioxide emissions, equivalent to the annual carbon dioxide absorption capacity of a 3848 ha plantation forest. This study summarizes energy-saving measures for energy users and identifies the areas for making energy saving to provide an energy efficiency baseline.

    Full Text Available The course, technical progresses, and achievements of energy conservation of China steel industry (CSI during 1980–2010 were summarized. Then, the paper adopted e-p method to analyze the variation law and influencing factors of energy consumptions of large- and medium-scale steel plants within different stages. It is pointed out that energy consumption per ton of crude steel has been almost one half lower in these thirty years, with 60% as direct energy conservation owing to the change of process energy consumption and 40% as indirect energy conservation attributed to the adjustment of production structure. Next, the latest research progress of some key common technologies in CSI was introduced. Also, the downtrend of energy consumption per ton of crude steel and the potential energy conservation for CSI during 2011–2025 were forecasted. Finally, it is indicated that the key topic of the next 15 years’ research on the energy conservation of CSI is the synergistic operation of material flow and energy flow. It could be achieved by the comprehensive study on energy flow network optimization, such as production, allocation, utilization, recovery, reuse, and resource, according to the energy quantity, quality, and user demand following the first and second laws of thermodynamics.

    In consideration of the future CDM project, feasibility study was made on the energy conservation/cost reduction in national textile factories in Egypt. In textile factories in Egypt, the steam by oil fueled boiler is used in dyeing, drying and other production processes. In this study, studied were the energy conservation effect, greenhouse effect gas reduction effect and economical efficiency in the case of using electric power/steam by the natural gas fueled cogeneration system. As a result of the study, the energy conservation effect in 6 national textile factories became 13% on average, which equals to the conservation of 15,000 toe per year. The greenhouse effect gas reduction effect also became 13%, which equals to the reduction of approximately 46,000 t-CO2 per year. As to the economical efficiency, the depreciation period of investment became 4.0-8.6 years (5.6 years on average). In the light of the operation period of cogeneration facilities of 15 years, it was indicated that the system was very advantageous. (NEDO)

    The pulp and paper industry is highly energy intensive. In view of the spiralling fuel prices and rising power costs, there is an urgent need to conserve energy through better management of various operations in the industry, from the optimal utilization of the forest residues to the shipment of the final product. The total energy concept, e.g., energy generation, distribution and utilization in Indian paper industry is discussed. The need for an energy audit is emphasized and the formats of energy reporting forms are included. Short and long term measures to be enforced to achieve energy savings in the pulp and paper mills are outlined. Some important energy conservation approaches are also discussed. Factors affecting energy efficiency in a pulp and paper mill are reviewed. Some areas where sustained R and D efforts should be focused to make the paper industry nearly self-sufficient in energy generation and utilization are also given. It is essential to have a National Energy Policy clearly defining achievable targets of energy conservation for industry. The Indian paper industry could advantageously form its own committee to review the operation of the various mills in the country and come out with concrete solutions for higher energy efficiency and more effective conservation of energy.

    The Height of Land Wind Park has an installed capacity of 1000 MW and is located near Churchill Falls. The project will cost $2.5 billion, and will provide 3 terawatt hours of electricity per year, as well as 2000 direct and indirect jobs during construction, and a further 200 jobs during the project's operation and maintenance phase. The project is expected to provide power to 500,000 homes and displace the equivalent of 3 million tonnes of carbon dioxide (CO 2 ) per year. Pending regulatory approval, construction will begin in 2007 and is expected to be phased over 3 years. The Labrador Ventus Limited Partnership was established by Ventus Energy and the Metis Development Corporation to develop the project, and has been structured to ensure maximum economic benefits to the people of Labrador. The partnership is open to additional partners that will bring value to the project. To date, the project has conducted prospecting field trips, obtained Transport Canada permits and Crown land use permits. An interconnection application was filed in 2005, and a meteorological tower was installed for a 1-year wind resource assessment. The environmental assessment procedure has been initiated, and meetings have been held with Newfoundland and Labrador Hydro. The proposed ownership structure for Height of Land Wind Park includes the Innu Economic Development Limited Partnership; Newfoundland and Labrador Hydro; the Metis Development Corp.; and Ventus Energy Inc. It was concluded that while the project continues to receive positive feedback and community support, unresolved land claim negotiations must be resolved, and there are several competing projects underway in the region. The project has been hampered by the lack of an interconnection policy in Newfoundland and Labrador. refs., tabs., figs

    2005-02-15

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

  17. Zero energy growth for Canada: necessity and opportunity

    Energy Technology Data Exchange (ETDEWEB)

    Brooks, D B

    1976-05-01

    In resolving questions about the energy growth rate in Canada, two basic routes are possible: to allow costs and prices to adjust sufficiently to bring supply and demand into balance, presumably at a lower energy growth rate, or to adopt the normative propostion that some explicit choice should be made about target rates of energy consumption. This essay suggests that Canada should follow the latter route and that policies should be adopted to move Canada to a position close to zero energy growth by the year 2000. The thesis is that such a target is both feasible and desirable, with emphasis on the latter. Desirability is defined very broadly to include economic, social and environmental aspects. This essay attempts to answer basic questions about the nature of a low-energy alternative for Canada. In particular, energy conservation is associated with a larger construct called the conserver society, involving goals such as moderation in scale and in rates of change, emphasis on personal contact and community, and maintenance of a wide diversity of people and activities, as well as with the more obvious connotations of reduced material throughput and an improved environment. In this construct, zero energy growth is quite compatible with Canadian conditions that require major attention to space heating and a large transportation sector. Combined with the fact that the energy intended to be conserved includes all non-renewable energy and any other energy produced under capital-intensive, centralized conditions, but not small solar, biomass or wind plants, which can be accepted without destroying the conserver society values, it is felt that there is abundant energy for Canadians to live very well. 41 refs., 3 figs., 3 tabs.

    AVOTAN, avoparcin is a glycopeptide antibiotic manufactured by Cyanamid (UK) via the fermentation of a strain of Streptomyces candidus. The gross energy requirement of manufacturing avoparcin is calculated and compared with the gross energy savings of feed utilisation when used in animal feeding regimes for broiler chickens, pigs, beef cattle and dairy cows for milk production. Avoparcin improves farm animal production in terms of liveweight gains and feed conversion efficiency. So, by conserving animal feed it conserves the energy which would have been expended to produce that animal feed. The energy savings thus calculated range from one to two orders of magnitude on an energy ratio basis and so are very significant. The widespread use of avoparcin in world agriculture is therefore very beneficial in an energy conservation context. (Author)

    1985-06-01

    This study relies on extensive, existing survey data and new analyses to develop information that would help design a marketing plan to achieve energy conservation in new manufactured homes. Existing surveys present comprehensive information about regional manufactured home occupants and their homes that are relevant to a potential conservation marketing plan. An independent analysis of the cost-effectiveness of various efficiency improvements provides background information for designing a marketing plan. This analysis focuses on the economic impacts of alternative energy conservation options as perceived by the home owner. Identifying impediments to conservation investments is also very important in designing a marketing plan. A recent report suggests that financial constraints and the need for better information and knowledge about conservation pose the major conservation investment barriers. Since loan interest rates for new manufactured homes typically exceed site-built rates by a considerable amount and the buyers tend to have lower incomes, the economics of manufactured home conservation investments are likely to significantly influence their viability. Conservation information and its presentation directly influences the manufactured home buyer's decision. A marketing plan should address these impediments and their implications very clearly. Dealers express a belief that consumer satisfaction is the major advantage to selling energy efficient manufactured homes. This suggests that targeting dealers in a marketing plan and providing them direct information on consumers' indicated attitudes may be important. 74 refs.

  1. The evolution of nuclear energy Opportunities for the industry

    International Nuclear Information System (INIS)

    Dominguez, M. T.

    2013-01-01

    At the turn of the XXI century, the world energy context underwent a significant change due mainly to the increases in the demand for energy in the developing countries, a rise in gas prices and increased government support of clean energies in response to environmental issues. these boundary conditions led rapidly to renewed interest in nuclear energy worldwide. The phrase a Renaissance in nuclear energy was included in almost all energy forecasts. Unexpectedly, however, just then years later the panorama changed once again: unconventional gas appeared as new energy source, the world financial crisis hampered investment, and the demand for energy fell. This panorama has lowered expectations with regard to the size of the nuclear energy renaissance to a less buoyant but more balance scenario of nuclear energy deployment that we could now dub as the evolution of nuclear energy. This article describes how fission nuclear energy has continuously been evolving to adjust itself to these changing scenarios, and, in particular, how it is being adapted itself to todays vision of the role of the nuclear energy in the long term. The analysis in this paper focuses on those programs that could bring opportunities for Spanish nuclear industry participation. Starting with the development programs affecting existing reactors already in operation, the analysis moves on the new builds of Light Water Reactors (LWR) Generation III+, to then address, in two sections, Research Reactors and finally, the opportunities presented by Generation IV technologies. The development of fusion technology is not covered in this paper. (Author)

    Modern land-use planning and conservation strategies at landscape to country scales worldwide require complete and accurate digital representations of river networks, encompassing all channels including the smallest headwaters. The digital river networks, integrated with widely available digital elevation models, also need to have analytical capabilities to support resource management and conservation, including attributing river segments with key stream and watershed data, characterizing topography to identify landforms, discretizing land uses at scales necessary to identify human-environment interactions, and connecting channels downstream and upstream, and to terrestrial environments. We investigate the completeness and analytical capabilities of national to regional scale digital river networks that are available in five countries: Canada, China, Russia, Spain, and United States using actual resource management and conservation projects involving 12 university, agency, and NGO organizations. In addition, we review one pan-European and one global digital river network. Based on our analysis, we conclude that the majority of the regional, national, and global scale digital river networks in our sample lack in network completeness, analytical capabilities or both. To address this limitation, we outline a general framework to build as complete as possible digital river networks and to integrate them with available digital elevation models to create robust analytical capabilities (e.g., virtual watersheds). We believe this presents a global opportunity for in-country agencies, or international players, to support creation of virtual watersheds to increase environmental problem solving, broaden access to the watershed sciences, and strengthen resource management and conservation in countries worldwide.

    This updated market assessment for capturing water conservation opportunities in the Federal sector is based on a new analytical approach that utilizes newly available data and technologies. The new approach fine-tunes the original assessment by using actual Federal water use, which is now tracked by DOE (as compared to using estimated water use). Federal building inventory data is also used to disseminate water use by end-use technology in the Federal sector. In addition, this analysis also examines the current issues and obstacles that face performance contracting of water efficiency projects at Federal sites.

    Energy demand has increased continuously due to advancement in technology and living standards of a large section of people resulting in a wide gap between supply and demand. One of the approaches to reduce this gap would be the adoption of measures of energy conservation in general and the efficient use of energy particularly in motor. This paper presents a review of the research activity in the field of efficiency optimization of three-phase induction motor drive. The approach is analyzed and the better option of energy conservation are identified.

    Access to clean, affordable and reliable energy has been a cornerstone of the world's increasing prosperity and economic growth since the beginning of the industrial revolution. Our use of energy in the twenty-first century must also be sustainable. Solar and water-based energy generation, and engineering of microbes to produce biofuels are a few examples of the alternatives. This Perspective puts these opportunities into a larger context by relating them to a number of aspects in the transportation and electricity generation sectors. It also provides a snapshot of the current energy landscape and discusses several research and development opportunities and pathways that could lead to a prosperous, sustainable and secure energy future for the world.

  7. Energy conservation and the residential and commercial sector

    Science.gov (United States)

    1975-01-01

    A detailed analysis of energy conservation actions relevant to the residential and commercial sector has led to the conclusion that the potential for savings is great. The task will not be easy, however, since many of the actions require significant life style changes that are difficult to accomplish. Furthermore, many of the conservation actions cited as instant solutions to the energy crisis are those with only mid to long term potential, such as solar energy or heat pumps. Three significant conservation approaches are viable: adjusting price structure, mandating actions, and educating consumers. The first two appear to be the most feasible. But they are not without a price. Higher utility bills adversely affect the poor and the elderly on fixed incomes. Likewise, strict mandatory measures can be quite distasteful. But the effect of alternatives, such as voluntary savings accomplished through education processes, is minimal in a nation without a true conservation ethic.

Interviews were conducted with energy conservation professionals to identify and evaluate existing energy conservation programs, and interviews were conducted with consumers who had evaluated selected programs previously reviewed by the professionals. Information was also gathered on energy conservation activities of consumers surveyed. A directory of 34 energy conservation programs was also compiled. Some of the conclusions reached in this report are as follows. There is a need for an information system to gather data on existing conservation programs in order to increase the knowledge of relevant parties as to the outcomes of operating programs. This would help evaluation and improvement of current programs and suggest new program possibilities. The professionals rated six of the 34 programs highly, including the Energuide and the Canadian Home Insulation Program (CHIP). Retrofitting programs for houses are recommended for continuation and expansion, with some consideration given to linking these kinds of programs with home audit programs. In the private transport sector, any new conservation programs should be thoroughly tested on a small scale before widespread implementation, as evidence indicates that certain programs favorably evaluated by professionals may not be received favorably by consumers. 3 refs., 24 tabs.

  9. Overview topic paper on mass media energy conservation communications

    Vertinsky, P; Vertinsky, I

    1979-02-01

    The utilization of information diffusion strategies to increase energy conservation knowledge and practices among the general population in Canada is discussed in terms of 5 media functions: information dissemination, remedial behavior modification, lifestyle decisions, initiating conservation action, and crisis management. Each of these functions is critically addressed in terms of media mix, message content and form, timing and intensity, exposure, and specific target populations. The diffusion strategies are then organized into a matrix of policy options to enable the appropriate one to be selected. Four major categories of energy conservation information considered are the nature of the energy problem, methods of conservation, results of conservation, and the individual consumer decision-making process. Heavy television exposure suggests this medium has enormous potential for informing Canadians on conservation issues. Print seems to be the main source of detailed, specialized, and sophisticated kinds of information. However, despite wide media availability, large numbers of the population consistently escape contact with widely reported information. Behavioral modification to change undesirable energy habits is examined from the perspectives of initial change and cultural/social change required to sustain new lifestyles. The use of mass media during crisis situations may be of essential importance for implementation of future energy policies. Information dissemination and responses to the mass media do not appear to have the same patterns during crisis and non-crisis situations. 279 refs.

    2013-12-01

    Full Text Available With the ever-growing demand for renewable energy sources, energy harvesting from natural resources has gained much attention. Energy sources such as heat and mechanical motion could be easily harvested based on pyroelectric, thermoelectric, and piezoelectric effects. The energy harvested from otherwise wasted energy in the environment can be utilized in self-powered micro and nano devices, and wearable electronics, which required only µW–mW power. This article reviews pyroelectric energy harvesting with an emphasis on recent developments in pyroelectric energy harvesting and devices at micro/nanoscale. Recent developments are presented and future challenges and opportunities for more efficient materials and devices with higher energy conversion efficiency are also discussed.

    Germany reinvents itself with the energy policy turnaround as well as climate protection. In doing so, Germany holds a special position worldwide. The transformation of the electric power supply by wind turbines, photovoltaic power plants, biomass conversion plants and avoidance of CO{sub 2} have already been set up. What formerly employed the competent engineers, is interesting the entire society against the backdrop of current political decisions - since the electricity costs increase and a previously saved power supply are increasingly being questioned. The current energy policy turnaround and climate protection measures can only be sensible if there are benefits for the nature conservation, the security of supply with electrical power and the cost. Under this aspect, the author of the book under consideration reports on the opportunities, threats, advantages and disadvantages of the German route. The competitiveness of our country, the security against power outages, the tax burden, the cost of energy and finally the environment are at stake. The upcoming problems can not be solved by political wishful thinking but only with solid technology, economy and environmental protection.

    This note aims at examining whether environmental policies associated with energy transition are either a brake on, or an opportunity for economic growth. In order to so, the authors compare France's situation with that of its economic partners (Germany, Spain, Italy) in terms of energy price, and of share of employment in polluting industries. They also examine the influence of an increase of energy prices on employment and competitiveness of French manufacturing companies. They finally show that energy transition implies a structural change which may result in an actual creation of green jobs. They finally propose three recommendations regarding economic policy

    1977-12-01

    Under the sponsorship of the United States Department of Energy, a Model Code for Energy Conservation in New Building Construction has been developed by those national organizations primarily concerned with the development and promulgation of model codes. The technical provisions are based on ASHRAE Standard 90-75 and are intended for use by state and local officials. The subject of regulation of new building construction to assure energy conservation is recognized as one in which code officials have not had previous exposure. It was also determined that application of the model code would be made at varying levels by officials with both a specific requirement for knowledge and a differing degree of prior training in the state-of-the-art. Therefore, a training program and instructional materials were developed for code officials to assist them in the implementation and enforcement of energy efficient standards and codes. The training program for Energy Conservation Tehnology for Plan Examiners and Code Administrators (ECT Series 200) is presented.

    Energy conservation, energy efficiency and demand side management are defined and the role played in the promotion and advancement of energy efficiency objectives by the Canadian Energy Efficiency Alliance are explained. Direct and indirect economic and environmental benefits and the potential impacts in terms of savings and jobs are discussed, with examples of successful greenhouse gas emission reduction programs by industry. The total potential for energy efficiency in Canada is estimated at 18 per cent lower energy use by 2010, and 33 per cent by 2020, assuming that specific policy recommendations and other cost effective efficiency measures are implemented. Overall conclusions are that there is a large potential for cost-effective energy savings over and above of what has been done already. Furthermore, utilities can play a leading role in realizing these efficiencies, and in the process achieve substantial benefits for themselves

    Quantum systems described by parametrized Hamiltinians are studied in a general context. Within this context, the classification scheme of Avron-Seiler-Simon for non-degenerate energy bands is extended to cover general parameter spaces, whole their sum rule is generalized to cover cases with degenerate bands as well. Additive topological quantum numbers are defined, and these are shown to be conserved in energy band ''collisions''. The conservation laws dictate that when some invariants are non-vanishing, no energy gap can develop in a set of degenerate bands. This gives rise to a series of splitting rules

    The policy instruments considered include: greater reliance on market forces; research and development; information, education and demonstration programs; tax incentives and sanctions; mortgage and finance programs; and regulations and standards. The analysis starts with an explanation of the barriers to energy conservation in the residential and commercial sectors. Individual policy instruments are described and evaluated with respect to energy conservation, economic efficiency, equity, political impacts, and implementation and other transitional impacts. Five possible strategies are identified: (1) increased reliance on the market place; (2) energy consumption tax and supply subsidies; (3) Building Energy Performance Standards (BEPS) with no sanctions and no incentives; (4) BEPS with sanctions and incentives (price control); and (5) BEPS with sanctions and incentives (no price controls). A comparative analysis is performed. Elements are proposed for inclusion in a comprehensive strategy for conservation in new buildings.

  12. Energy conservation techniques as innovations, and their diffusion

    Energy Technology Data Exchange (ETDEWEB)

    Darley, J M

    1978-04-01

    Many effective products, procedures, and techniques for achieving energy conservation have been discovered by researchers. This paper focuses on the conditions under which these procedures and techniques will be adopted voluntarily. It is suggested, first, that an economic incentive for the utilization of those energy-conserving techniques is not a sufficient condition for their adoption, and second, that a psychologically-based theory of the diffusion of innovation will identify the critical variables for promoting the adoption of energy-conserving products and techniques. Based on preliminary, small-scale observations of homeowners' reactions to a complex, time-controlled thermostat, the initial parameters of a diffusion theory for energy innovation are suggested.

  13. Travelling energy systems: knowledge transfer for energy efficiency and conservation from European to Australian building projects

    2009-07-01

    Energy efficiency and conservation in the Australian built environment have not yet been implemented to any great extent. Despite favourable prerequisites, such as vast windswept unpopulated areas suitable for wind power and many hours of direct sunlight in most populated areas, electricity is mainly generated by burning brown coal and buildings are poorly equipped for hot summers and cool winters. Australia urgently needs to convert to alternative energy sources and implement energy efficiency measures, since its carbon dioxide emissions per capita are among the highest in the world. In a recent major redevelopment in Sydney, the Carlton and United Brewery (CUB) site knowledge of energy efficiency and conservation measures used in European buildings was transferred and implemented in local designs and infrastructure. This knowledge came mainly from urban planning and developments in London, but also from high-profile architectural firms based in Paris and Germany. The arrival of this knowledge in Australia led to phases when the knowledge was translated and enacted in local spaces and the constituent ideas were transformed into action. The present research is based on ten months of ethnographic fieldwork in which the planning and design of the CUB site was observed. The results of the study identify barriers to and opportunities for energy system knowledge transfer between different cultures and local spaces. Substantial time must be spent overcoming cultural barriers, so the involved parties can start talking the same language. This is not only true for stakeholders operating in different continents, but for stakeholders operating in different local arenas in the same country.

    Full Text Available The lighting system provides many options for cost-effective energy saving with low or no inconvenience. Lighting improvements are excellent investments in most public buildings, it is usually cost-effective to address because lighting improvements are often easier to make than many process upgrades.For public buildings, the easy no and low cost options to help save money and improve the energy performance are:Understand energy use.Identify optionsPrioritize actionsMake the changes and measure the savings.Continue managing energy efficiency.The challenge is to retrofit traditional lamps with LED lamps of good quality. The benefits of LED light bulbs are long-lasting, durable, cool, mercury free, more efficient, and cost effective.The light Emitting Diode (LED bulb uses a semiconductor as its light source, and is currently one of the most energy efficient and quickly developing types of bulbs for lighting. LEDs increasingly are being purchased to replace traditional bulbs. LEDs are relatively more expensive than other types of bulbs, but are very cost-effective because they use only a fraction of electricity of traditional lighting methods nd can last for longer.Benchmarking guides decision makers to policies aimed at the energy sector through better understanding of energy consumption trends nationwide, e.g.: energy price, moderating, peak demand, and encouraging sectors, low energy expansions.The “Improving Energy Efficiency Project of Lighting and Appliances” carried out energy audits and implemented opportunities of energy saving in lighting for different type of public buildings.To rationalize the use of energy by giving guidelines to consumers, the IEEL&A project prepared some brochures.This paper leads with the results of case studies as energy audits, opportunities in lighting systems, energy saving and CO2 reduction.

    Brondum, Jack; Palchick, Susan

    2012-12-01

    Greenhouse gases result mainly from the combustion of fossil fuels in energy use. Restaurants use large amounts of energy in their operation but systematically gathered information about such use is lacking. Hennepin County Human Services and Public Health Department surveyed owners of licensed restaurants to assess their energy use and awareness of energy conservation measures. Of 434 owners surveyed, 276 (63.6%) returned completed surveys. Responses indicated that large pluralities or majorities of restaurant owners often were aware of energy-efficient methods of operation and the means to achieve greater efficiency but used such means much less frequently. For example, 57% of respondents were familiar with the U.S. Environmental Protection Agency's Energy Star program, but only 33% of this group actually used Energy Star appliances. Given the gap between awareness and practice, opportunities for consultation and outreach to restaurant owners about energy-efficient business operation are manifold.

    The goal of LINKKI - the research program on consumer behavior and energy conservation - was to promote energy conservation by seeking potential and means for energy conservation in the short term in areas that are linked with consumers` activities and choices. Research has been conducted in the following sectors: home, buildings, traffic, and indirect energy consumption. This report discusses the results obtained through the program against a more general background of people`s ways of life and the various factors explaining energy consumption. The report assesses the differences discovered between households, for instance, with respect to demographic factors, life situations, motivation towards conservation, information needs, and attitudes to information. These factors were evaluated in their role as barriers to energy conservation. The research projects have surveyed various ways of disseminating information (e.g. advice, feedback on consumption, computer programs, energy labels), as well as information needs and decision-making processes existing among households. Research conducted in the sector of indirect energy consumption has produced data on conservation potential with respect to the selection of foods and the organization of leisure activities. In the sector of energy consumption in traffic, assessments have been made concerning the conservation potential that can be achieved by reorganizing activities and data transmission (e.g. distance work, flexible working time). The prerequisites for the actualization of this potential have also been studied. Similarly, the opportunities of reducing energy consumption in traffic by means of prices, taxation systems and regional ticket systems have been analyzed

    Regulatory requirements introduced by the new policy of energy transition will force the French industry to look for alternatives to oil and coal. Within this context, this publication contains contributions proposed by industrial and academic experts which aim at discussing how the French industry can seize the opportunity of energy transition to strengthen itself. The authors discuss the issue of competitiveness, the role of de-carbonated electricity, the context of energy transition in France, the evolutions and transformations of the energy market. They also outline the lack of an energy vision in France, the role of the electricity grid as a vector of energy transition, and the fact that the debate on energy transition did not result in concrete solutions

    The Association of Southeast Asian Nations (ASEAN) is one of the most dynamic economic regions of the world. Its economy is linked with its diverse energy resources, high-level urbanization, and rapid industrialization. ASEAN's growing economy in the last two decades has increased the concern of sustainable development in the face of deteriorating energy security, environmental pollution, and economic hardship in energy investment. However, opportunities exist to tackle these issues. Increasing energy efficiency (both supply and demand side), exploitation of renewable energy resources (mostly hydro), and an integrated approach on energy resource management are some of the important approaches toward the sustainable energy path. Because the options are capital-intensive, cooperation and development of appropriate institutional structures and decision mechanism across the region are urgently needed

    Sri Lanka is a tropical, predominantly agricultural island with a mixed population. The economy is rapidly expanding since 1977. So far the country is self-sufficient in rice, which is the staple food of the population. Indiscriminate cutting of forests for firewood resulted in a disastrous upsetting of the rain pattern. The existing capacity of hydro-electric power plants is not adequate to meet the demands of the rapidly growing industries and of households where the use of appliances increases dramatically with the progress of the economy. Periodic cut-offs of electric power supply became necessary. These are very harmful to industry. In order to keep the balance of payments in equilibrium, the government is fostering the development of new sources of foreign income, such as tourism and export of gems and spices. Remedies used to master the energy crisis are: the building of new hydroelectric plants, reforestation; introduction of ''kerosene stamps'' which will restrict the sale of this product at subsidized prices to the needy only; encouraging the use of fuel-efficient motorcycles in preference to automobiles; introduction (in cooperation with Honda) of alcohol-powered motorcycles; appointment of a Ministerial Committee endowed with broad powers to formulate and implement national energy policy. Although the general energy situation in Sri Lanka is rather bleak for the moment, it is confidently hoped that these measures will bear fruit in the long run.

  3. Promoting energy conservation in the rural areas

    Taale, K.D.

    2001-01-01

    It is estimated that more than 70% of the population of Ghana live in the rural areas. Cooking and heating in these areas are mainly achieved by fuelwood and other biomass. Although wood is a renewable energy resource, this is only so if it is grown faster than it is consumed. Firewood consumption exceeds forest growth in Ghana and other developing countries. Added to this, is the fact that the World's wood resource is used for such purposes as sawn timber, clearing of land and felling trees for agricultural purposes, etc. If our forests are to be preserved it is this population that has to be targeted. One method of reducing fuelwood demand is to encourage alternative supplies such as biogas (methane). Rural populations could be mobilized to construct bio-latrines in their communities to make use of the biogas generated to cook their food and also for heating purposes. Through levies, funds could be generated to undertake such projects in each community. Before this could be possible, a lot of education will have to be undertaken by the Renewable Energy unit of the Ministry of Mines and Energy. This is because many people are apprehensive of the idea of cooking with gas derived from their own feces. Some of the benefits to be derived from such a project are the use of the effluent slurry as high quality organic manure for farming.

    2013-01-01

    Conservation laws of energy and momentum for nonrelativistic plasmas are derived from applying Noether's theorem to the action integral for the Vlasov-Poisson-Ampère system [Sugama, Phys. Plasmas 7, 466 (2000)]. The symmetric pressure tensor is obtained from modifying the asymmetric canonical pressure tensor with using the rotational symmetry of the action integral. Differences between the resultant conservation laws and those for the Vlasov-Maxwell system including the Maxwell displacement current are clarified. These results provide a useful basis for gyrokinetic conservation laws because gyrokinetic equations are derived as an approximation of the Vlasov-Poisson-Ampère system.

    2016-01-01

    Full Text Available The designated government buildings have implemented and administered energy program under the energy development and promotion Act 2007 for many years continuously until 2015. Appointment person responsible for energy, performing energy management and implementing the energy conservation work plan and measures are legal requirements for the designated buildings. Therefore, the ministry of Energy has launched the project to support the implementation of energy management. The aim of the project was to create the energy management system in the designated government buildings, and to reduce energy consumption. In this paper, the evaluation of the project has been presented from the achievements of 839 designated government buildings. The energy saving is more than 440 ktoe/year. This is about 3% of energy consumptions of buildings.

  6. Energy conserving site design case study: Shenandoah, Georgia. Final report

    The case study examines the means by which energy conservation can be achieved at an aggregate community level by using proper planning and analytical techniques for a new town, Shenandoah, Georgia, located twenty-five miles southwest of Atlanta's Hartsfield International Airport. A potentially implementable energy conservation community plan is achieved by a study team examining the land use options, siting characteristics of each building type, alternate infrastructure plans, possible decentralized energy options, and central utility schemes to determine how community energy conservation can be achieved by use of pre-construction planning. The concept for the development of mixed land uses as a passively sited, energy conserving community is based on a plan (Level 1 Plan) that uses the natural site characteristics, maximizes on passive energy siting requirement, and allows flexibility for the changing needs of the developers. The Level 2 Plan is identical with Level 1 plan plus a series of decentraized systems that have been added to the residential units: the single-family detached, the apartments, and the townhouses. Level 3 Plan is similar to the Level 1 Plan except that higher density dwellings have been moved to areas adjacent to central site. The total energy savings for each plan relative to the conventional plan are indicated. (MCW)

  12. Energy conservation investments: A comparison between China and the US

    International Nuclear Information System (INIS)

    Lin, Jiang

    2007-01-01

    Growth in energy consumption in China has soared from 2001 to 2004, driven largely by a booming economy and heavy investment in infrastructure and housing. In response, China has poured billions of dollars of investment in building power plants-at a rate of one large power plant (1000 MW) per week. In fact, China in 2004 has added the entire generating capacity of California or Spain in a single year. In contrast, investment in energy conservation projects has weakened considerably in recent years. This paper examines trends in energy efficiency investments in China and the US. The comparison highlights the potential of energy conservation investments in addressing China's current energy crisis as well as the inadequacy of such investments in China. Finally, the paper outlines a few scenarios for appropriate levels of investments in energy efficiency in China in the future

    The efficiency of a mercury-rare gas electrical discharge, which forms the basis of a fluorescent lamp, can be increased about 5 percent simply by increasing the concentration of mercury-196 from 0.146 percent (natural) to about 3 percent. These findings can be implemented immediately without any significant change in the process of manufacturing of this widely used source of illumination, provided that mercury-196 can be obtained economically. The potential energy savings for the United States are estimated to be worth in excess of $200 million per year.

    2013-01-01

    The residential sector accounts for one-fifth of global energy consumption, resulting from the requirements to heat, cool, and light residential dwellings. It is therefore not surprising that energy efficiency in the residential market has gained importance in recent years. In this paper, we examine awareness, literacy and behavior of households with respect to their residential energy expenditures. Using a detailed survey of 1721 Dutch households, we measure the extent to which consumers are aware of their energy consumption and whether they have taken measures to reduce their energy costs. Our results show that “energy literacy” and awareness among respondents is low: just 56% of the respondents are aware of their monthly charges for energy consumption, and 40% do not appropriately evaluate investment decisions in energy efficient equipment. We document that demographics and consumer attitudes towards energy conservation, but not energy literacy and awareness, have direct effects on behavior regarding heating and cooling of the home. The impact of a moderating factor, measured by thermostat settings, ultimately results in strong variation in the energy consumption of private consumers. - Highlights: • We use a detailed survey of 1,721 Dutch households to measure awareness and conservation behavior in energy consumption. • Energy literacy and awareness among residential households is low. • 40 percent of the sample does not appropriately evaluate investment decisions in energy efficient equipment • Demographics and consumer attitudes affect behavior regarding heating and cooling of a home

  15. Smarter by Degrees. Towards new instruments for energy conservation policy

    2006-11-15

    Achieving the government's ambition of 1.5 to 2% energy savings annually will require every effort to be made. Households, small and medium-sized businesses, government and semi-governmental institutions (energy-extensive energy consumers) will also be able to make an important contribution. This group represents considerable savings potential of about 300 PJ. There are three types of instruments that may be used for this group to achieve the desired goal (1) obligation/prohibition, i.e., regulations and standards to demand energy efficient investments (construction, facilities, equipment, etc.); (2) price incentives (subsidies/taxes) to promote energy-efficient solutions; (3)enticement/influence, appealing to reason (information, arguments) or emotion to promote the right choice/behaviour. Analysis of past experiences presents the conclusion that so-called soft instruments are sometimes briefly effective but often have little or no effect. The Council believes, however, that such a conclusion is premature, as certain conditions were not met in the past that were very important to effectiveness. First, soft instruments must be implemented consistently and over the long term (about 4 years, at least). Appealing to the very diverse consumers also requires a custom approach. The tone of the conservation policy must also be more in tune with changing trends in society. Citizens must especially be appealed to in terms of cost advantages, responsible energy consumption (good housekeeping) and comfort, whereas the emphasis in the past lay on decency, solidarity and thrift. Specific action perspectives must also be offered. Partly on the basis of experience, such as in waste collection, the Council concludes that a well-assembled mix of soft and hard instruments will be necessary to encourage energy conservation. It is clear that soft instruments alone can be expected to produce unsatisfactory results. Therefore, a combination of soft and hard instruments is advocated

  19. Airplane energy use and conservation strategies

    Energy Technology Data Exchange (ETDEWEB)

    Pilati, D.A.

    1974-05-01

    Domestic commercial airplane fuel use is examined as a function of stage length. A fuel use model is developed using the eight most popular airplanes. Short flights are very fuel inefficient; a 100-mile flight consumes 2.5 times as much fuel per passenger-mile than a 1,000-mile flight. Half of today's flights are for distances under 260 miles. Fuel consumption for purposes other than flying directly between airports is examined. Over 10% of total fuel use is for those portions of the flight in which no enroute distance is achieved. Delays account for at least 4.2% of the fuel consumption and auxiliary power units use over 1%. Fuel requirements for attempting to recover lost time and for fuel ferrying are also discussed. Airplane fuel efficiency can be increased in the short term by operational changes, particularly by increasing the load factor. A load factor increase from 50 to 60% would reduce airplane fuel use by 16% for the same traffic. Other options include reducing cruise speeds, increasing cruise altitudes, and changing ground operations. Each of these strategies offer savings of 1 to 3%. Total transportation energy use can be reduced by shifting air passengers to ground modes, especially for the inefficient short-stage traffic. Net energy savings for diverting half the flights under 200 miles to buses or trains is equivalent to 6% of the fleet fuel use. (6 tables, 6 fig., 36 references)

    A new challenge to reduce energy usage has emerged in Swedish industry because of increasing energy costs. Energy usage in the Swedish powder coating industry is about 525 GWh annually. This industry has a long and successful record of working towards reduced environmental impact. However, they have not given priority to energy saving investments. Electricity and LPG, for which end-user prices are predicted to increase by as much as 50 - 60% by 2020, are the main energy carriers used in the plants. This paper presents the results of two detailed industrial energy audits conducted with the aim of quantifying the energy efficiency potential for the Swedish powder coating industry. Energy auditing and pinch analysis methods were used to identify possible energy housekeeping measures and heat exchanging opportunities. The biggest users of energy within the plants are the cure oven, drying oven and pre-treatment units. The energy use reduction by the housekeeping measures is 8 - 19% and by thermal heat recovery an additional 8 - 13%. These measures result in an average energy cost saving of 25% and reduction of carbon dioxide emissions of 30%. The results indicate that the powder coating industry has a total energy efficiency potential of at least 20%

  1. Key role for nuclear energy in global biodiversity conservation.

    Modern society uses massive amounts of energy. Usage rises as population and affluence increase, and energy production and use often have an impact on biodiversity or natural areas. To avoid a business-as-usual dependence on coal, oil, and gas over the coming decades, society must map out a future energy mix that incorporates alternative sources. This exercise can lead to radically different opinions on what a sustainable energy portfolio might entail, so an objective assessment of the relative costs and benefits of different energy sources is required. We evaluated the land use, emissions, climate, and cost implications of 3 published but divergent storylines for future energy production, none of which was optimal for all environmental and economic indicators. Using multicriteria decision-making analysis, we ranked 7 major electricity-generation sources (coal, gas, nuclear, biomass, hydro, wind, and solar) based on costs and benefits and tested the sensitivity of the rankings to biases stemming from contrasting philosophical ideals. Irrespective of weightings, nuclear and wind energy had the highest benefit-to-cost ratio. Although the environmental movement has historically rejected the nuclear energy option, new-generation reactor technologies that fully recycle waste and incorporate passive safety systems might resolve their concerns and ought to be more widely understood. Because there is no perfect energy source however, conservation professionals ultimately need to take an evidence-based approach to consider carefully the integrated effects of energy mixes on biodiversity conservation. Trade-offs and compromises are inevitable and require advocating energy mixes that minimize net environmental damage. Society cannot afford to risk wholesale failure to address energy-related biodiversity impacts because of preconceived notions and ideals. © 2014 The Authors Conservation Biology published by Wiley Periodicals, Inc. on behalf of Society for Conservation Biology.

    Options available for improving energy efficiency in the Netherlands are listed and discussed. As detailed in this report, there is still substantial scope for reducing energy consumption in the production and use of energy carriers, much of it not only attractive from the perspective of society as a whole but also profitable for the actors concerned. By exploiting these opportunities, sustainability targets can be cost-effectively met. The report examines why so much potential is still not being utilised and how this can be remedied. Following a description of the potential for energy conservation, a package of smart, effective policies is recommended to secure this potential [Dutch] De mogelijkheden van energiebesparing in Nederland zijn in kaart gebracht. In deze notitie wordt aangetoond dat bij energiebesparing bij het gebruik en bij de productie van energiedragers nog veel onbenut, maar maatschappelijk aantrekkelijk potentieel ligt, waarvan een groot deel rendabel is. Benutting daarvan leidt ertoe dat de duurzaamheidsdoelen op een kosteneffectieve manier behaald kunnen worden. We hebben onderzocht waarom veel potentieel nu niet benut wordt en hoe dat wel kan gebeuren. Deze analyse beschrijft het besparingspotentieel en biedt voorstellen voor een pakket aan slimme, effectieve beleidsinstrumenten om dit potentieel te realiseren: door inzet van verplichtingen en door energiebesparing aantrekkelijker te maken.

    This report summarizes the responses to a mail survey sent to superintendents and other administrators of public school districts. The survey was part of an evaluation project for the USDOE Institutional Conservation Program (ICP). The goal of the project is to identify the most successful energy conservation measures (equipment and activities) available to the institutional buildings sector. To accomplish this goal, four specific research objectives were defined: To determine the impact of the ICP grants program on fostering energy efficiency and saving energy; to determine key characteristics of institutional conservation efforts outside the federal program; To determine the technical, organizational, and Institutional conditions that create the opportunity for energy conservation measures (ECMS) to be most effective; and to identify key technology transfer opportunities. This report focuses on those characteristics of school districts (and the schools within those districts) that might influence the identification, implementation, operation, and impacts of institutional energy conservation efforts. Information about institutional characteristics was gathered through a mail survey of public school districts and private schools. The first mailing resulted in responses from 90 of the 823 public school districts selected through a combination cluster-and-stratification sampling technique and 64 of the 1,700 private schools selected as a stratified random sample. Remaining project resources were used to collect data to achieve a statistically sound sample of a total of 250 public school districts by telephone interviews. In doing so, some questions had to be dropped. Responses from both the mall surveys and the telephone interviews of public school districts were combined into one data set. This report describes results for all 250 districts.

    There has been an increased interest in using sustainability indicators for evaluating the impacts of development and conservation projects. Past and recent experiences have shown that sustainability indicators can be powerful tools for measuring the outcomes of various interventions, when used appropriately and adequately. Currently, there is a range of methods for applying sustainability indicators for project impact evaluation at the environment–development interface. At the same time, a number of challenges persist which have implication for impact evaluation processes especially in developing countries. We highlight some key and recurrent challenges, using three cases from Kenya, Indonesia and Brazil. In this study, we have conducted a comparative analysis across multiple projects from the three countries, which aimed to conserve biodiversity and improve livelihoods. The assessments of these projects were designed to evaluate their positive, negative, short-term, long term, direct and indirect impacts. We have identified a set of commonly used sustainability indicators to evaluate the projects and have discussed opportunities and challenges associated with their application. Our analysis shows that impact evaluation processes present good opportunities for applying sustainability indicators. On the other hand, we find that project proponents (e.g. managers, evaluators, donors/funders) face challenges with establishing full impacts of interventions and that these are rooted in monitoring and evaluation processes, lack of evidence-based impacts, difficulties of measuring certain outcomes and concerns over scale of a range of impacts. We outline key lessons learnt from the multiple cases and propose ways to overcome common problems. Results from our analysis demonstrate practical experiences of applying sustainability indicators in developing countries context where there are different prevailing socio-economic, cultural and environmental conditions.

    Many jurisdictions, including Nova Scotia (NS), have implemented policies and programs around energy. The NS government has targeted energy efficiency and more renewable energy as two main policy areas. The NS Department of Agriculture has taken initiative to provide support to implement energy conservation, energy efficiency and renewable energy opportunities in recent years but have these programs and policies been effective? A baseline energy use survey was conducted in 2005 and responses from mail surveys in 2012 (n = 273, 11.4% response rate) were used to measure the change in NS farm energy use data reported for 2004 and 2011. There have been significant reductions in energy use on NS farms. On average, NS farmers spent $8790 on energy expenses in 2011 compared to $11,228 in 2004. Adjusting for inflation, this is a 32% decrease, despite energy commodity pricing increases beyond the inflation rate. This is likely due to a decrease in energy use and a shift from gasoline use to diesel use. By the end of 2012, 36.0% of NS farmers (more than 860) had received some level of support to evaluate their energy options. This includes 410 energy audits compared to only 36 by the end of 2005. - Highlights: • Nova Scotia farmers decreased their energy costs by 32% between 2004 and 2011. • Energy reductions were likely due to decreased energy use and a shift in fuel use. • An estimated 374 NS farms had an energy audit between 2005 and 2012.

    Energy Technology Data Exchange (ETDEWEB)

    1981-03-01

    The dry milling process for the conversion of grain to fuel ethanol is reviewed for the application of energy conservation technology, which will reduce the energy consumption to 70,000 Btu per gallon, a reduction of 42% from a distilled spirits process. Specific energy conservation technology applications are outlined and guidelines for the owner/engineer for fuel ethanol plants to consider in the selection on the basis of energy conservation economics of processing steps and equipment are provided. The process was divided into 5 sections and the energy consumed in each step was determined based on 3 sets of conditions; a conventional distilled spirits process; a modern process incorporating commercially proven energy conservation; and a second generation process incorporating advanced conservation technologies which have not yet been proven. Steps discussed are mash preparation and cooking, fermentation, distillation, and distillers dried grains processing. The economics of cogeneration of electricity on fuel ethanol plants is also studied. (MCW)

  11. Energy-Efficiency Improvement Opportunities for the Textile Industry

    Energy Technology Data Exchange (ETDEWEB)

    China Energy Group; Hasanbeigi, Ali

    2010-09-29

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

    This paper provides an overview of the proven influence between anthropogenic actions such as those related with energy production and use on the natural environment. With the adverse perspectives of continued chemical changes occurring worldwide the paper also presents opportunities that can continue to ensure a more sustainable growth in harmony with the environment. A transition for a more efficient and environmentally correct final use of energy is needed in future in such a way as to diminish the conflicts between development and environment. Different scenarios aiming to provide the ideal routes for development to occur addressing sustainability indicators are studied. Some typical options for a more sustainable future include improved energy efficiency, more renewable energy and advanced energy technologies. National programs undertaken in Brazil such as those of the ethanol and bio diesel have a proven impact in the search for a sustainable future worldwide and should be further emphasized in future by means of the ratification of the Kyoto Protocol.

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

    Green buildings uses processes that are environmentally responsible and resource-efficient throughout a building's life-cycle. In these buildings Certain energy conservative and environment friendly steps are considered and implemented from design, construction, operation, maintenance and renovation. In present era no doubt new technologies are constantly constructed and used in creating greener structures, energy efficient buildings. The common objective is to reduce the overall impact of the built environment on human health using available energy efficiently. To increase the efficiency of the System or the building, Onsite generation of renewable energy through solar power, wind power, hydro power, or biomasscan significantly reduce the environmental impact of the building. Power generation is generally the most expensive feature to add to a building. Any how power generation using renewable sources that is Solar system may further enhance energy conservation ideas. Power Factor improvement can also be another source of efficient tool for efficient use of Electrical Energy in green buildings. In developing countries a significant amount of Electrical Energy can be conserved and System efficiency as a whole can be increased by Power Factor correction. The reverse flow of power can be locally engaged instead of creating extra stress and opposition to the existing grid lines.

  17. ‘God is my forest’ – Xhosa cultural values provide untapped opportunities for conservation

    Directory of Open Access Journals (Sweden)

    2012-05-01

    Full Text Available In South Africa conservation is still largely framed in terms of Western scientific values, with a focus on material benefits to local communities, whilst little is known about the intangible values local people attach to nature and biodiversity. We explored the cultural, spiritual and emotional relationships with nature expressed by Xhosa people, within the Maputaland-Pondoland-Albany Hotspot, as well as the activities that mediate this relationship. A descriptive research approach was applied to document the emotions, meanings and values associated with landscape elements. This approach included group and individual interviews and ‘walk-in-the-woods’ interviews and participatory mapping exercises. Respondents portrayed a strong, although not always easily articulated, appreciation for nature, especially ihlathi lesiXhosa (‘Xhosa forest’, vegetation types within the Thicket Biome. Activities such as collecting fuelwood and other resources, hunting and time spent at initiation schools were described as key opportunities for spending time in nature. The benefits of being in nature were ascribed not only to the physical experience of the forest environment and its biota, but also to the presence of ancestral spirits. Being in nature thus contributes significantly to the physical, mental and spiritual well-being of local people, and is also integral to their sense of cultural identity. This study has made it clear that maintenance of biodiversity and natural vegetation is as much in the interest of the local community’s well-being as it is in the interest of conservation planners. We recommend that cultural values be incorporated into local conservation plans.

  18. Leveraging Carbon Cycling in Coastal Wetlands for Habitat Conservation: Blue Carbon Policy Opportunities (Invited)

    Science.gov (United States)

    Sutton-Grier, A.

    2013-12-01

    Recent scientific studies suggest that the carbon sequestered and stored in coastal wetlands (specifically mangroves, salt marshes, and seagrass meadows) is an important, previously not well-recognized service provided by these ecosystems. Coastal wetlands have unique characteristics that make them incredibly efficient, natural carbon sinks with most carbon stored belowground in soils. Based on this new scientific evidence, there is growing interest in leveraging the carbon services of these habitats (termed 'blue carbon') to develop new policy opportunities to protect and restore coastal wetlands around the globe. The overall goal is to take full advantage of the carbon services of these habitats in order to ensure and maintain the many benefits provided to society by these habitats - including natural climate, food security, and storm protection benefits - and to enhance the resiliency of coastal communities and economies around the world. This presentation will give an update on some of the policy opportunities including: (1) examining how the implementation of U.S. federal policies can be expanded to include carbon services of ecosystems in order to improve management and decision making; (2) developing an international blue carbon community of science and practice to provide best practice guidance for protection and restoration of blue carbon habitats; and (3) developing innovative financing mechanisms for coastal conservation including carbon market credits for wetlands. Finally, the presentation will conclude by highlighting some of the most pressing blue carbon scientific gaps that need to be filled in order to support these developing policies.

    2005-01-01

    This paper represents the findings of the preliminary energy-audits performed by the Rational Use of Energy Division at the National Energy Research Center (NERC), as well as the findings of a detailed energy-audit carried out in the largest Ceramic plant in Jordan (Jordan Ceramic industries).These studies were preceded by a survey of the ceramic factories in Jordan. The survey was carried out in 1997. The performed preliminary energy-audits showed that an average saving-potential in most of theses plants is about 25 % of the total energy-bills in these plants, which constitutes a considerable portion of the total production-cost. This fact was verified through the detailed energy-audit performed by NERC team for the largest Ceramic Plant in Jordan in June 2003, which showed an energy-saving potential of about 30 %. This saving can be achieved by some no-cost or low-cost measures, in addition to some measures that need reasonable investments with an average pay-back period of about two years. This detailed energy-audit covered electrical systems, refrigeration systems, compressed-air systems, and kilns. The results of the detailed energy-audit can be disseminated to other Ceramic plant, because of the similarity in the production process between these plants and the plant where the detailed energy-audit was carried out.

    1978-08-01

    The Aerospace Corporation, the City Government, and the Board of Education of Jersey City have conducted a group of energy-conservation experiments to explore a number of conservation techniques believed to offer quick payback and to be of wide applicability. Experiments include the updating and/or rehabilitation of the energy-consuming features of old buildings and installation of devices designed to minimize energy losses caused by human error or laxity. Specific examples include: upgrading of the deteriorated and inefficient steam-distribution system of the city hall (originally constructed in 1894); an extensive program of reducing infiltration in an old school building; use of several timing devices in connection with heating, ventilation, and lighting systems to encourage energy-conservation practices; retrofit of school classrooms with high-pressure sodium lamps; and demonstration of practical and cost-effective ways of increasing the efficiency of conventional steam boilers. The report presents: the nature of the selected experiments; technical, human, and organizational factors that proved significant in performing and evaluating the experiments; discussions of observations and lessons learned; and general recommendations for an extended program of energy conservation in local governments. It is emphasized that, in retrofit of existing buildings, the unexpected is commonplace; and the habits and attitudes of building occupants are elements of the system that must always be taken into account. This report shows the benefits of energy saving, cost saving, and added comfort that may be attained by retrofitting old buildings, noting typical complications that arise. The effectiveness of the conservation methods is presented in terms of costs relative to effective payback periods calculated from results of their application in Jersey City.

    Rising concern about energy resource availability and energy prices in Jordan, cost of energy has become an issue that cannot be ignored in Jordan's industrial sector. In this study, energy auditing in a meat production factory related to poultry company was carried out. Based on the collected data and the conservation laws of energy, the performance of steam boilers, domestic hot water boilers, compressors, refrigeration systems, chillers, pumps, daily consumption of diesel and water were reviewed. The percentage of energy consumed by the refrigeration units, with respect to the total energy consumed, has been estimated. The results demonstrated a normal operation with thermal efficiency of 80.66% for the steam boiler, ability to save 18818.99 JD by installing economizer with payback period of 0.637 year and a 12.3% reduction of the energy cost achieved by reducing the blow down rate. The rate of diesel consumption was reduced by 12.87% over the last period of the study as a result of the recommendations that have been submitted to the technicians and professionals. The sum of 22223.77 JD can be saved by using heavy fuel oil instead of diesel oil. Moreover, this study demonstrated that energy saving can be considered as an ideal choice to increase profit and promote competition within the poultry industry if the company adopts all the proposals and recommendations that have been offered by this study.

    1976-12-01

    Energy conservation is currently a major concern of the cement industry. A comparison of data supplied by the U.S. Federal Energy Administration with that gathered in an extensive private study incorporating 29 wet cement plants indicates that a significant reduction of the energy consumed can be accomplished by decreasing the amount of dust generated in the process. Energy saving of 8 percent through dust suppression appears possible by increasing the slurry moisture and by using hammermills rather than impactors as the crushing technique.

  5. Financing Opportunities for Renewable Energy Development in Alaska

    Energy Technology Data Exchange (ETDEWEB)

    Ardani, K.; Hillman, D.; Busche, S.

    2013-04-01

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

    2017-01-01

    We report a new particle in cell (PIC) method based on the semi-implicit approach. The novelty of the new method is that unlike any of its semi-implicit predecessors at the same time it retains the explicit computational cycle and conserves energy exactly. Recent research has presented fully implicit methods where energy conservation is obtained as part of a non-linear iteration procedure. The new method (referred to as Energy Conserving Semi-Implicit Method, ECSIM), instead, does not require any non-linear iteration and its computational cycle is similar to that of explicit PIC. The properties of the new method are: i) it conserves energy exactly to round-off for any time step or grid spacing; ii) it is unconditionally stable in time, freeing the user from the need to resolve the electron plasma frequency and allowing the user to select any desired time step; iii) it eliminates the constraint of the finite grid instability, allowing the user to select any desired resolution without being forced to resolve the Debye length; iv) the particle mover has a computational complexity identical to that of the explicit PIC, only the field solver has an increased computational cost. The new ECSIM is tested in a number of benchmarks where accuracy and computational performance are tested. - Highlights: • We present a new fully energy conserving semi-implicit particle in cell (PIC) method based on the implicit moment method (IMM).

  16. Energy conservation and energy prices: the Hungarian experience

    International Nuclear Information System (INIS)

    Molnar, L.

    1997-01-01

    The main sources of emissions into the outdoor air are from the energy sector (e.g. power plants), industry, the transport sector and the residential sector (buildings). The danger from most of these emissions is the fact that heat plants and boilers of residential buildings in particular, are usually in the areas where people live and work and therefore their emissions may have a direct effect on health. The best way to improve this situation - to diminish emissions and to improve air quality - is to increase the efficiency of both energy production and use. This also has important consequences for the economic use of the national energy carrier stock and diminishes the need to import energy which increases the competitiveness of goods produced. The Hungarian government has set out an Energy Saving Programme to address, among other things the fact that the Hungarian average energy consumption per capita is less than the EU average but the energy intensity (the necessary energy to produce 1 USD GDP) is 3.5-4.0 times higher than the EU average. It has been shown that the best way to save energy is to invest in energy-conscious behaviour and training. Recent studies in public and residential buildings have shown that there is a potential for high energy saving in Hungarian buildings which is independent from the building technology used. Also, the pay-back times of investment in the building envelope are significantly higher than the pay-back times of investment in heating-ventilating or control systems, while the energy saved was of the same magnitude.

  17. Supply Chain Management for Improved Energy Efficiency: Review and Opportunities

    2017-10-01

    Full Text Available Energy efficiency represents a key resource for economic and social development, providing substantial benefits to different stakeholders, ranging from the entities which develop energy efficient measures to everyone in society. In addition to cost savings, multiple benefits can be achieved by supporting a better alignment between energy issues and strategic business priorities: e.g., improved competitiveness, profitability, quality, etc. Thus, energy efficiency can be a strategic advantage, not just a marginal issue, for companies. However, most firms, especially small and medium enterprises (SMEs, face many problems and, in some cases, hostility when trying to effectively implement energy efficiency actions. The most dominant barriers are the access to capital and the lack of awareness (especially in terms of life cycle cost effects. The supply chain viewpoint represents one of the main opportunities for overcoming those barriers and improving energy performance even for weaker companies. Since the current literature on energy efficiency and practical approaches to ensure energy efficiency mainly focus on energy performance on a single-firm basis, this paper aims to provide a systematic review of papers on the integration of energy efficiency in supply chain design and management published in academic journal, thereby defining potential research streams to close the gaps in the literature. A number of literature reviews have been published focusing on specific aspects of sustainable or on green supply chain management; however, to the best of our knowledge, no review has focused on the energy efficiency issue. Firstly, the present paper shows how considering energy consumption in supply chain management can contribute to more energy-efficient processes from a systemic point of view. Then, the review methodology used is defined and the sampled papers are analyzed and categorized based on the different approaches they propose. From these

  19. Combining interviewing and modeling for end-user energy conservation

    Goldblatt, David L.; Hartmann, Christoph; Duerrenberger, Gregor

    2005-01-01

    Studying energy consumption through the lens of households is an increasingly popular research avenue. This paper focuses on residential end-user energy conservation. It describes an approach that combines energy modeling and in-depth interviews for communicating about energy use and revealing consumer preferences for change at different levels and intervention points. Expert knowledge was embodied in a computer model for householders that calculates an individual's current energy consumption and helps assess personal savings potentials, while also bringing in socio-technical and economic elements beyond the user's direct control. The paper gives a detailed account of this computer information tool developed for interviewing purposes. It then describes the interview guidelines, data analysis, and main results. In general, interview subjects overestimated the environmental friendliness of their lifestyles. After experience with the program, they tended to rate external (technological, societal) factors as somewhat stronger determinants of their consumption levels than personal (behavioral and household investment) factors, with the notable exception of mobility. Concerning long-term energy perspectives, the majority of subjects felt that society has the ability to make a collective choice towards significantly lower energy consumption levels. Interviewees confirmed that the software and interactive sessions helped them think more holistically about the personal, social, and technological dimensions of energy conservation. Lessons can be applied to the development of future energy communication tools

The objective of the study was to identify renewable generation opportunities that would facilitate Rancheria energy independence through SRR owned and operated power projects. These generation facilities were to be located either on or near the reservation. Specifically, the Rancheria was interested in the viability of generating electric power using biomass and wind fuel resources. Initial research identified that a very small portion of the community's energy could be offset by renewable energy generation due to the low solar resource in this area, and the lack of significant wind or biomass resources on or near reservation land. Some larger projects were identified which offered little or no benefit to the Rancheria. As a result, the scope of this study was changed in October 2006 to focus on energy efficiency opportunities for key reservation facilities, with a continued analysis of smaller renewable energy opportunities within reservation boundaries. The consulting team initially performed a resource analysis for biomass and solar generation opportunities in the region of the Rancheria. It was quickly concluded that none of these options would yield renewable power for the Rancheria at costs competitive with current utility sources, and that any larger installations would require substantial funding that may not be available. Having made these conclusions early on, the study effort was redirected and the team investigated each of the major Rancheria buildings to look for solar, wind and conservation opportunities. The buildings were audited for energy use and the roof areas were examined for exposure of solar radiation. Wind resources were also investigated to determine if smaller wind turbines would offer power generation at a reasonable cost.

  1. Climate change mitigation through energy efficiency : opportunities in Atlantic Canada

    Canada's total energy use is expected to increase by 20 per cent between 2005 and 2020. Studies have suggested that successful energy efficiency initiatives could reduce growth in demand by up to 50 per cent, while reducing greenhouse gases (GHGs) by an estimated 40 per cent. Energy use comprises approximately 65.4 per cent of total expenditures for most businesses. Atlantic region industries contribute nearly 7 per cent of Canadian industrial energy consumption while contributing 5 per cent to the Canadian industrial gross domestic product (GDP). Energy efficiency practices adopted by industry operators in the Maritimes included modifications to boilers, process cooling equipment, motors, compressed air equipment, lighting and HVAC systems. Energy efficiency performance values in the Maritimes range from 11 to 100 per cent, with an average of 65 per cent. Opportunities for improving energy efficiency include inefficient lighting, leaking faucets, poor heat distribution, and inappropriate solid waste segregation. Cost savings for various energy efficiency measures were presented. Case studies of various eco-efficiency programs conducted at plants and businesses in the Maritimes were also included. tabs., figs.

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

    More and more local bottom-up energy initiatives are emerging. Those involved encounter many barriers during the realization of their ideas. As the generation of renewable energy is mostly included, these local initiatives contribute to the targets set at regional, national and EU level. At the same time, they are an indication that end-users themselves want to be part of the energy transition. What are the reasons for citizens to organize themselves and start and initiative? What kind of barriers do they encounter? What does this mean for roles and responsibilities of professionals? And to what kind of opportunities does this lead for products and services? Answers to these questions provide a solid starting point to develop methods and instruments to stimulate, facilitate and upscale local energy initiatives. This paper bundles the outcomes of three workshops and three additional interviews in the Netherlands as part of the European E-hub project. Conclusions can be drawn on needs and drivers, barriers, risks and solutions (lessons learned), possible roles for professionals and opportunities for new products and services.

  4. Skating on Thin Ice: Evolution of Conservation in Energy Policy

    Science.gov (United States)

    Gibbons, Jack

    2009-05-01

    Why are we physicists so often drawn into the nexus of energy policy and governance? There are several explanations. First, we are quite accustomed to this phenomenon of ``cause and effect,'' so we instinctively examine those two ends as well as the connections between them (i.e., what happens between a lump of coal and a light bulb). That way of thinking makes energy production and consumption intiminately connected and ``conservation'' naturally becomes a technological strategy rather than an appendage. Strangely, however, ``conservation'' in our society (called ``The Cowboy Economy'' by economist Kenneth Boulding) has been widely interpreted as competitive with supply and ridiculed as only a minor option, entailing denial of an amenity. After nearly a half-century of dialogue, innovation, and frustration, the rationality of what I call the ``physics'' perspective seems to have come of age. The evolution of relevant science and technology and public policy has advanced markedly, reflected and sustained at the national level by a succession of organizations. The Congressional Office of Technology Assessment, the Federal Office of Energy Conservation, the Federal Energy Administration, the U.S. Department of Energy, and the Office of Science and Technology Policy. Not surprisingly, physicists continue to play key roles in the inculcation of science and analysis into the policy and governance. This requires, as implied by C.P. Snow, a bridging and strengthening of the thin ice between science and society. We still have a long road to travel.

    1981-05-01

    The costs and effectiveness of non-regulatory options relative to those of a regulatory approach are analyzed. Nonregulatory program alternatives identified are: information and education programs, tax incentives and disincentives, and mortage and finance programs. Chapter 2 briefly reviews survey data to assess present public awareness of energy issues and energy-efficient building design. Homebuyer and homebuilder surveys are reviewed and conservation motivations are discussed. Chapter 3 examines the provision of technical and economic information to various factors affecting building design decisions. This approach assumes that the economic incentives and technical means to achieve energy conservation goals already exist but that critical information is lacking. Chapter 4 examines how adjustments to the tax structure could enhance economic incentives and counter economic disincentives for energy conservation. Qualifying buildings for tax benefits would almost certainly require certification of design energy consumption. The effectiveness of tax incentives would depend in part on dissemination of public information regarding the incentives. Chapter 5 examines subsidies, such as subsidized mortgages and loan guarantees, which lower the cost of money or other costs but do not change the market structure facing the consumer. Certification that buildings qualify for such treatment would probably be required. Chapter 6 presents recommendations based on the study's findings. (MCW)

    The present study is an initial effort to apply social system analysis to transportation energy conservation, in order to prepare the ground for a team effort of transportation and energy specialists, regional planners, policy analysis and generalists, and government administrators - with additional imputs from commerce, industry and the community at large. The task of this study has been to inventory the principal factors and inputs in the field of transportation energy demand and possible conservation, estimate their magnitudes and relations, and arrange in a tentative but reasoned pattern - where there were before only so many scattered data, technical studies with a limited focus, sectoral programs and decisions, and vague impressions about the serviceability, the impacts and the social value of the product.

  7. NCSU solar energy and conservation house. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1981-10-01

    A passive solar energy house has been built adjacent to the NCSU McKimmon Continuing Education Center. The house contains a two-story embedded sunspace, two Trombe walls, active solar hot water heating, thermal storage in a rock filled ceiling/floor, and numerous research treatments, and energy conservation features. (See attached photo brochure; Appendix 1). The house is completely decorated and furnished in an attractive manner and the exterior architecture is traditional and has broad consumer appeal. It is also thoroughly instrumented to monitor performance. The house is open to the public on weekends and numerous people come to visit on their own initiative and others take advantage of the close proximity to McKimmon while there attending conferences. The house will influence and motivate large numbers of people to consider solar and energy conservation facets in their homes and will provide data to substantiate performance to prospective home buyers and meaningful data on design and construction for builders.

  9. Targeting water and energy conservation using big data

    2016-12-01

    Water conservation is often the most cost effective source of additional water supply for water stressed regions to maintain supply reliability with increasing population and/or demands, or shorter-term droughts. In previous research we demonstrated how including energy savings of conserved water can increase willingness to adopt conservation measures, at the same time that increases energy and GHG emissions savings. But the capacity to save water, energy and GHG emissions depends fundamentally in the economic benefits for customers and utilities. Utilities have traditionally used rebates, subsidies or incentives to enhance water conservation. But the economic benefits originated by these rebates depend on the actual savings of the water, energy and GHG emissions. A crucial issue that is not considered in the financial analysis of these rebates is the heterogeneity in water consumption, resulting in rebating households that actually do not need improvements in certain appliances. Smart meters with end-use disaggregation allow to consider this heterogeneity and to target rebates. By using an optimization approach that minimizes water and energy residential costs—accounting for retrofit costs and individual benefits according to previous levels of consumption—we are able to assess economically optimal rebate programs both for customers and utilities. Three programs are considered: first, same economic incentives are provided to all households and then they do their optimal decisions; second, traditional appliance-focused rebates are assessed; and third, utilities provide only rebates to those households that maximize water, energy or GHG emissions savings. Results show that the most economically efficient options for households are not the best options for utilities, and that traditional appliance-focused rebates are much less optimal than targeted rebates.

  10. Designing effective incentives for energy conservation in the public sector

    Science.gov (United States)

    Drezner, Jeffrey Alan

    Understanding why government officials behave in certain ways under particular circumstances is an important theme in political science. This research explores the design of policies and incentives targeted at public sector officials, in particular the use of market based policy tools in a non-market environment, and the influence of that organizational environment on the effectiveness of the policy. The research examines the case of Department of Defense (DoD) facility energy management. DoD energy policy includes a provision for the retention of savings generated by conservation activities: two-thirds of the savings is retained at the installation generating the savings, half to used for further investment in energy conservation, and half to be used for general morale, welfare, and recreation activities. This policy creates a financial incentive for installation energy managers to establish higher quality and more active conservation programs. A formal written survey of installation energy managers within DoD was conducted, providing data to test hypotheses regarding policy effectiveness and factors affecting policy implementation. Additionally, two detailed implementation case studies were conducted in order to gain further insights. Results suggest that policy design needs to account for the environment within which the policy will be implemented, particularly organizational culture and standard operating procedures. The retention of savings policy failed to achieve its intended outcome---retention of savings for re-investment in energy conservation---because the role required of the financial management community was outside its normal mode of operation and interests and the budget process for allocating resources did not include a mechanism for retention of savings. The policy design did not adequately address these start-up barriers to implementation. This analysis has shown that in order for retention of savings, or similar policies based on market

  11. Energy conservation and the environment: conflict or complement

    Energy Technology Data Exchange (ETDEWEB)

    Schipper, L.

    1978-09-01

    The policy discussion following the Oil Embargo was clouded with fears of a return to a primitive existence based on drastically reduced energy inputs to society, or, on the other hand, an abandoning of environmental goals, allegedly a major barrier to development of new energy supplies. Often the energy use associated with environmental improvements was cited as a reason for expanding energy supplies, as if to say that a conflict existed between a clean environment and reductions in energy use. Or it was argued that a relaxation of environmental goals would lower the direct costs of harvesting and using energy and thereby alleviate the need for energy conservation. It has also been argued that the geopolitics of energy alone will force us to substitute riskier or ''dirtier'' energy sources for relatively clean oil and gas. Indeed, there is no question that the relationship among energy, the environment, and economic well-being is complicated. This essay sorts out many of the confusing aspects in order to show how goals relating to the efficient use of energy are aligned both with traditional economic goals and with modern environmental goals. To do this the author analyzes in depth the role of energy in the economy and, using examples, traces the origins of many of the misconceptions about that role--misconceptions that have inhibited a profound discussion of energy-related goals.

    1989-01-01

    An integral expression for the gyrokinetic total energy of a magnetized plasma, with general magnetic field configuration perturbed by fully electromagnetic fields, was recently derived through the use of a gyrocenter Lie transformation. It is shown that the gyrokinetic energy is conserved by the gyrokinetic Hamiltonian flow to all orders in perturbed fields. An explicit demonstration that a gyrokinetic Hamiltonian containing quadratic nonlinearities preserves the gyrokinetic energy up to third order is given. The Poisson-bracket formulation greatly facilitates this demonstration with the help of the Jacobi identity and other properties of the Poisson brackets

    2016-12-01

    The future of conventional energy in Canada is uncertain. World oil prices have suffered steep declines recently and there are no strong arguments for recovery in the foreseeable future. The country is now engaged in serious debates and discussions over the value of GHG emissions, pipelines, oil and gas operations, and renewable energy. Oilsands deposits in northern Alberta require long-term investment and decades of consistent sales to repay those investments. The election of more progressive governments in Alberta and Canada may provide the national and global credibility and opportunity to address the environmental problems caused by Oilsands and other fossil fuel developments. The discussion will focus on the possible ways forward for Canada to diversify the regional and national economy with renewable energy networks, thereby meeting our Paris GHG emission reduction commitments. The end goal of this work is to see the Canadian economy decarbonized within two decades.

    Cooking is the main energy consuming activity in Ghana. This is mainly due to a generally low material standard of living, but also because the cooking process itself is energy inefficient. The fuel for cooking in Ghana is mainly biomass either in the form of wood, agricultural residues or charcoal....... An energy chain for the cooking process is established and the possible conservation options are surveyed in kitchen performance tests in Abodom in the tropical zone of Ghana. The energy consumption for the food preparation has been measured and energy saving options have been determined for some parts...... point has been reached. Most cooks tend to continue using a high heat supply even though it is not necessary. This process is often carried out without lid on the pot even though the use of lid will reduce the energy loss considerably. It is also concluded that the average fuelwood consumption in Abodom...

    Renewable energy will potentially make an important contribution towards the dual aims of meeting carbon emission reduction targets and future energy demand. However, some technologies have considerable potential to impact on the biodiversity of the environments in which they are placed. In this study, an assessment was undertaken of the realistic deployment potential of a range of renewable energy technologies in the UK, considering constraints imposed by biodiversity conservation priorities. We focused on those energy sources that have the potential to make important energy contributions but which might conflict with biodiversity conservation objectives. These included field-scale solar, bioenergy crops, wind energy (both onshore and offshore), wave and tidal stream energy. The spatially-explicit analysis considered the potential opportunity available for each technology, at various levels of ecological risk. The resultant maps highlight the energy resource available, physical and policy constraints to deployment, and ecological sensitivity (based on the distribution of protected areas and sensitive species). If the technologies are restricted to areas which currently appear not to have significant ecological constraints, the total potential energy output from these energy sources was estimated to be in the region of 5,547 TWh/yr. This would be sufficient to meet projected energy demand in the UK, and help to achieve carbon reduction targets. However, we highlight two important caveats. First, further ecological monitoring and surveillance is required to improve understanding of wildlife distributions and therefore potential impacts of utilising these energy sources. This is likely to reduce the total energy available, especially at sea. Second, some of the technologies under investigation are currently not deployed commercially. Consequently this potential energy will only be available if continued effort is put into developing these energy sources

    1992-01-01

    The Bonneville Power Administration (Bonneville) has identified 101 plants in the Pacific Northwest that account for 80% of the region's industrial electricity consumption. These plants offer a precise target for a conservation program. PNL determined that most of these 101 plants were represented by 11 major industries. We then reviewed 36 major conservation technologies used in these 11 industrial settings to determine their potential environmental impacts. Energy efficiency technologies designed for industrial use may result in direct or indirect environmental impacts. Effects may result from the production of the conservation measure technology, changes in the working environment due to different energy and material requirements, or changes to waste streams. Industry type, work-place conditions, worker training, and environmental conditions inside and outside the plant are all key variables that may affect environmental outcomes. To address these issues this report has three objectives: Describe potential conservation measures that Bonneville may employ in industrial programs and discuss potential primary impacts. Characterize industrial systems and processes where the measure may be employed and describe general environmental issues associated with each industry type. Review environmental permitting, licensing, and other regulatory actions required for industries and summarize the type of information available from these sources for further analysis.

    1980-10-01

    Methods of encouraging energy conservation in multifamily housing by allocating energy costs to residents are discussed; specifically, methods appropriate for use in master metered buildings without equipment to monitor energy consumption in individual apartments are examined. Several devices available for monitoring individual energy consumption are also discussed plus methods of comparing the energy savings and cost effectiveness of monitoring devices with those of other means of promoting conservation. Specific information in Volume I includes a comparison study on energy use in master and individually metered buildings; types of appropriate conservation programs for master metered buildings; a description of the Resident Utility Billing System (RUBS); energy savings associated with RUBS; Resident reactions to RUBS; cost effectiveness of RUBS for property owners; potential abuses, factors limiting widespread use, and legal status of RUBS. Part I of Volume II contains a cost allocation decision guide and Part II in Volume II presents the RUBS Operations Manual. Pertinent appendices to some chapters are attached. (MCW)

  20. The ability of land owners and their cooperatives to leverage payments greater than opportunity costs from conservation contracts.

    Lennox, Gareth D; Armsworth, Paul R

    2013-06-01

    In negotiations over land-right acquisitions, landowners have an informational advantage over conservation groups because they know more about the opportunity costs of conservation measures on their sites. This advantage creates the possibility that landowners will demand payments greater than the required minimum, where this minimum required payment is known as the landowner’s willingness to accept (WTA). However, in recent studies of conservation costs, researchers have assumed landowners will accept conservation with minimum payments. We investigated the ability of landowners to demand payments above their WTA when a conservation group has identified multiple sites for protection. First, we estimated the maximum payment landowners could potentially demand, which is set when groups of landowners act as a cooperative. Next, through the simulation of conservation auctions, we explored the amount of money above landowners’ WTA (i.e., surplus) that conservation groups could cede to secure conservation agreements, again investigating the influence of landowner cooperatives. The simulations showed the informational advantage landowners held could make conservation investments up to 42% more expensive than suggested by the site WTAs. Moreover, all auctions resulted in landowners obtaining payments greater than their WTA; thus, it may be unrealistic to assume landowners will accept conservation contracts with minimum payments. Of particular significance for species conservation, conservation objectives focused on overall species richness,which therefore recognize site complementarity, create an incentive for land owners to form cooperatives to capture surplus. To the contrary, objectives in which sites are substitutes, such as the maximization of species occurrences, create a disincentive for cooperative formation.

  1. Survey of energy conservation in India: priorities and policy dimensions

    Energy Technology Data Exchange (ETDEWEB)

    Pachauri, R K

    1983-01-01

    The formulating and implementing of an energy conservation policy in India was delayed, because emphasis was placed upon an increase of energy production in the mistaken belief that this is tantamount to an improvement in the standard of life. Statistical data of energy production according to its source and of its consumption by individual sectors of the national economy are presented. They show that by far the largest turnover is in energy derived from firewood and vegetable and animal waste for domestic use in rural India. Although a very great potential for energy conservation exists in this domain, its implementation on a large scale is hardly practicable because it would affect many millions of village households with very different life styles dictated by varying natural conditions in individual areas of the country. Energy derived from oil and coal is used rather wastefully mainly because of obsolete equipment and technology. There is a vast scope for improvement in this area and appropriate measures have been initiated by the Government. The demand for oil derivatives for transportation is increasing dangerously, mainly because of dieselization of the national railways and of development of motorized road transport. A turnaround of this trend would require, however, a restructuring of the Indian transportation system.

    We analyze a volumetric formulation of lattice Boltzmann for compressible thermal fluid flows. The velocity set is chosen with the desired accuracy, based on the Gauss-Hermite quadrature procedure, and tested against controlled problems in bounded and unbounded fluids. The method allows the simulation of thermohydrodyamical problems without the need to preserve the exact space-filling nature of the velocity set, but still ensuring the exact conservation laws for density, momentum and energy. ...

This paper lists the proposed normatives and reports on CTI's progress in assembling groups of consultants from various sectors - public administration, end users, industrial firms, etc.

  8. Application of economic principles in energy conservation measures

    Energy Technology Data Exchange (ETDEWEB)

    Bhattacharyya, A

    1976-01-01

    The point of departure for the selection of any energy-conserving policy is the availability of (at least) two practical options or alternatives for policy maker at enterprise level. In real life, in the same point of time, or in the same geographical location, there could be several energy conservation options for the same industrial process. One need only set up a pairwise comparison of two options at a time and answer the question: which option is the most desirable from the energy conservation standpoint. Which option is the most desirable from the purchaser's point of view. If one takes both these factors into account, which option is socially the most desirable. We have explained two economic techniques (Life Cycle Cost (LCC), Market Acceptance) and their integration to compare two systems at a time. To begin with, a policy maker at enterprise level can carry out LCC. As technology progresses over time, Market Acceptance estimation may be warranted. Finally, Cost-Benefit Analysis may be applied to overall evaluation of competing projects which have involvement of large social groups, and wider foreign exchange implications.

    2017-01-01

    Using conservation of energy—a fundamental property of closed classical and quantum mechanical systems—we develop an efficient gradient-domain machine learning (GDML) approach to construct accurate molecular force fields using a restricted number of samples from ab initio molecular dynamics (AIMD) trajectories. The GDML implementation is able to reproduce global potential energy surfaces of intermediate-sized molecules with an accuracy of 0.3 kcal mol−1 for energies and 1 kcal mol−1 Å̊−1 for atomic forces using only 1000 conformational geometries for training. We demonstrate this accuracy for AIMD trajectories of molecules, including benzene, toluene, naphthalene, ethanol, uracil, and aspirin. The challenge of constructing conservative force fields is accomplished in our work by learning in a Hilbert space of vector-valued functions that obey the law of energy conservation. The GDML approach enables quantitative molecular dynamics simulations for molecules at a fraction of cost of explicit AIMD calculations, thereby allowing the construction of efficient force fields with the accuracy and transferability of high-level ab initio methods.

    This Final Report marks the end of the implementation stage of the project: 'Energy Conservation in Selected Buildings in Gdansk, Poland' supported by the Danish Environment-related Energy Sector Programme for Poland under the Danish Energy Agency. The residential and commercial sectors together with public buildings account for 40-45% of the total energy consumption and are dominated by the use of space heating and hot water. The sector has a significant over-consumption of energy, which first of all is due to the lack of or too weak incentives for the individual tenants to decrease the energy consumption. Bad thermal insulation of buildings and inefficient central heating systems with a widespread lack of measurement and automatic control systems give cause for extensive heat losses. The objective of the project has been to document the effects of energy savings in 18 multi-family houses when different types of energy saving measures are applied. These measures include thermal insulation of buildings, refurbishment of the heating system and introduction of individual billing system for heating and hot tap water. Energy audits of 18 buildings were performed by combination of on-site inspection of all buildings and data collection from the available drawings, technical descriptions, etc. The on-site inspection was carried out by use of an energy audit scheme specially developed for this project.

    Marquis, Fernand D. S.

    2012-03-01

    The transportation industry accounts for one quarter of global energy use and has by far the largest share of global oil consumption. It used 51.5% of the oil worldwide in 2003. Mobility projections show that it is expected to triple by 2050 with associated energy use. Considerable achievements recently have been obtained in the development of powder and powder-processed metallic alloys, metal matrix composites, intermetallics, and carbon fiber composites. These achievements have resulted in their introduction to the transportation industry in a wide variety of transportation components with significant impact on energy efficiency. A significant number of nano, nanostructured, and nanohybrid materials systems have been deployed. Others, some of them incorporating carbon nanotubes and graphene, are under research and development and exhibit considerable potential. Airplane redesign using a materials and functional systems integration approach was used resulting in considerable system improvements and energy efficiency. It is expected that this materials and functional systems integration soon will be adopted in the design and manufacture of other advanced aircrafts and extended to the automotive industry and then to the marine transportation industry. The opportunities for the development and application of new powder materials in the transportation industry are extensive, with considerable potential to impact energy utilization. However, significant challenges need to be overcome in several critical areas.

    Here, we present and analyze three powerful long-term historical trends in energy, particularly electrical energy, as well as the opportunities and challenges associated with these trends. The first trend is from a world containing a diversity of energy currencies to one whose predominant currency is electricity, driven by electricity’s transportability, exchangeability, and steadily decreasing cost. The second trend is from electricity generated from a diversity of sources to electricity generated predominantly by free-fuel sources, driven by their steadily decreasing cost and long-term abundance. These trends necessitate a just-emerging third trend: from a grid in which electricity is transported uni-directionally, traded at near-static prices, and consumed under direct human control; to a grid in which electricity is transported bi-directionally, traded at dynamic prices, and consumed under human-tailored agential control. Early acceptance and appreciation of these trends will accelerate their remaking of humanity’s energy landscape into one in which energy is much more affordable, abundant and efficiently deployed than it is today; with major economic, geo-political, and environmental benefits to human society.

    2008-01-31

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

  17. Application of energy conservation technologies in Indian industries

    Zubair, K.M.

    1992-01-01

    The quadrupling of oil prices in 1973 signaled the beginning of a crises period for the oil importing countries. It hampered the economic growth of developed and developing countries alike. The pace of industrialization slowed down, recession set in and the oil importing developing nations found their balance of payment situation steadily going worse. The second increase of oil prices in 1979 further compounded the problems. It did seem that the problem of economic growth and increasing debt burden was intractable as far as developing nations were concerned. Behind this turmoil were the faint stirrings of alternative actions that sought to wean the world from its oil and fossil fuel dominated economies. These alternatives ranged from harnessing renewable energy sources, such as solar, wind and biomass to implementing end-use energy efficiency strategies. A major lesson of the oil crunch era was that energy efficiency is tangible resource by itself that competes economically with contemporary energy supply options. In addition to this, four major national priorities, viz, economic competitiveness, utilization of scare capital for development, environmental quality and energy security through oil dependence provided an urgent rationale for saving energy. While conservation consciousness has already taken roots in Pakistan industry, it needs to be nurtured and gains need to be consolidated. The need of the hour is to take stock of the situation elsewhere, particularly in similar geographical and socio-economic situations, and plan for an energy efficient tomorrow. This article attempts to delineate the notable developments that have taken place in the application of energy conservation technologies in the Indian industries. These efforts have had a salutary effect on the Indian value added sector which was saddled with old plant and machinery designed in the era of cheap energy. (author)

  19. Business cycle and economic-wide energy intensity: The implications for energy conservation policy in Algeria

    Adom, Philip Kofi

    2015-01-01

    Despite the prevalence of voluntary and involuntary energy conservation policies, developing countries in Africa continue to struggle to achieve energy efficiency targets. Consequently, energy intensity levels have risen threatening the security of the energy system. This raises the important question: is there an economic state that induces agents to be energy conscious? In this study, we study the case of Algeria's energy intensity from 1971 to 2010. First, the paper argues that there is a certain economic state that economic agents find investing in energy conservation a viable option. Any state different from that would mean not investing in energy conservation. Second, the paper argues that the economy can do better even with an infinitesimal reduction in fuel subsidy, and that the gains in revenue from the policy can compensate for the negative socio-economic and equity impacts associated with such a policy. Third, the paper argues that, so long as, industrial expansion in the country move parallel with investment in technological innovation, long-term sustainable growth and energy conservation targets are jointly feasible. Fourth, the paper shows that income elasticity evolves with the business cycle, and the absorptive capability of the host country affects how FDI (foreign direct inflows) impact energy intensity. - Highlights: • Low income states inhibit fuel substitution and investment in energy conservation. • Income elasticity evolves as we pass through boom and recessionary periods. • The goals of sustainable growth and energy conservation are not mutually exclusive. • Absorptive capability affects the impact of FDI on energy intensity

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

  2. Nuclear energy and opportunity to strengthen the sustainable electricity sector

    2016-09-01

    The beginning of electricity in Mexico was through the use and exploitation of natural resources; as the demand grew, more generation power plants were required with great capacity and at the same time the fuels used varied, although, oil continued to be the main fuel. At present, due to the effects of climate change, the Conference of the Parties has proposed to reduce the consumption of fossil fuels to give way to clean energy (wind, solar, geothermal, nuclear, etc.), which entails gradually modifying the energy matrix of the electricity sector. The National Development Plan and the National Electricity Sector Development Program, this coordinated by the Energy Secretariat in Mexico, establish policies to promote sustainable development, increasing electricity generation through clean energy sources, including nuclear energy. However, such plans are not accurate in the strategy to be followed to ensure compliance with the increased participation of nuclear energy. This article proposes a nuclear program for the Mexican electricity sector, under the terms of a State policy, aimed at crystallizing a sustainable electricity development 2015-2036; considering that the application to the electricity sector constitutes a representative and justified example of the incorporation of environmental aspects in decision processes for the preservation of the environment. In order to determine the quantity and type of reactors, as well as the number of nuclear power plants and increase of the installed capacity, the general planning scheme of the electric sector was used, taking as reference the modeling criteria of the WASP planning system. Finally, is concluded that the electricity generated by fission of radioactive elements is an opportunity to fulfill the commitments made by Mexico at COP 21 and to meet in an environmentally friendly way the energy requirement that our country needs.

    The Energy Conservation Projects to benefit the railroad industry using the Norfolk Southern Company as a model for the railroad industry has five unique tasks which are in areas of importance within the rail industry, and specifically in the area of energy conservation. The NIU Engineering and Technology research team looked at five significant areas in which research and development work can provide unique solutions to the railroad industry in energy the conservation. (1) Alternate Fuels - An examination of various blends of bio-based diesel fuels for the railroad industry, using Norfolk Southern as a model for the industry. The team determined that bio-diesel fuel is a suitable alternative to using straight diesel fuel, however, the cost and availability across the country varies to a great extent. (2) Utilization of fuel cells for locomotive power systems - While the application of the fuel cell has been successfully demonstrated in the passenger car, this is a very advanced topic for the railroad industry. There are many safety and power issues that the research team examined. (3) Thermal and emission reduction for current large scale diesel engines - The current locomotive system generates large amount of heat through engine cooling and heat dissipation when the traction motors are used to decelerate the train. The research team evaluated thermal management systems to efficiently deal with large thermal loads developed by the operating engines. (4) Use of Composite and Exotic Replacement Materials - Research team redesigned various components using new materials, coatings, and processes to provide the needed protection. Through design, analysis, and testing, new parts that can withstand the hostile environments were developed. (5) Tribology Applications - Identification of tribology issues in the Railroad industry which play a significant role in the improvement of energy usage. Research team analyzed and developed solutions which resulted in friction

  6. California's crisis: An exploratory analysis of lifestyle, energy use, and conservation

    Science.gov (United States)

    Gossard, Marcia Hill

    Electricity is one of the most serious issues of the 21st century. Modern human societies have become completely dependent upon energy to power modern life---resulting in unwanted environmental effects. Although electricity itself is invisible, many of the most conspicuous household items consume the most electricity. The 2001 energy crisis in California provides a unique opportunity to study how people negotiated their lives during a time of perceived resource scarcity, increased electricity prices, and threats of blackouts. Combining cultural and environmental literatures, I argued that changes in resource availability (perceived or real) led to unsettled lives in which beliefs, rituals and ways of behaving began to be questioned---resulting in new patterns of action organized around lifestyle. As a conceptual framework, lifestyle can be useful for understanding the patterns of people's everyday lives, the objects they consume, and the degrees to which those lifestyles affect the environment. Using data from the California Residential Electricity Conservation Study (CRECS), this research explores the ways households navigated and used different conservation strategies during the summers of 2001 and 2002. Analysis of Behavioral Conservation Strategies (BCS) that require ongoing effort and attention by household residents in order to achieve successful conservation outcomes (e.g., turning off lights or regulating indoor temperature), and Consumer Investment Strategies (CIS) that are one-time purchases improving efficiency (e.g., purchase of an appliance or fixture) reveal different strategies of action over the two years. Wealth indicators and time constraints were less important for predicting conservation, while cultural differences and household composition were better predictors of conservation efforts. In addition, despite assumptions that people are unwilling to change their lifestyle in order to conserve electricity, households employed more strategies that

  7. Membranes: A Variety of Energy Landscapes for Many Transfer Opportunities.

    A membrane can be represented by an energy landscape that solutes or colloids must cross. A model accounting for the momentum and the mass balances in the membrane energy landscape establishes a new way of writing for the Darcy law. The counter-pressure in the Darcy law is no longer written as the result of an osmotic pressure difference but rather as a function of colloid-membrane interactions. The ability of the model to describe the physics of the filtration is discussed in detail. This model is solved in a simplified energy landscape to derive analytical relationships that describe the selectivity and the counter-pressure from ab initio operating conditions. The model shows that the stiffness of the energy landscape has an impact on the process efficiency: a gradual increase in interactions (such as with hourglass pore shape) can reduce the separation energetic cost. It allows the introduction of a new paradigm to increase membrane efficiency: the accumulation that is inherent to the separation must be distributed across the membrane. Asymmetric interactions thus lead to direction-dependent transfer properties and the membrane exhibits diode behavior. These new transfer opportunities are discussed.

  8. Soybean Opportunity as Source of New Energy in Indonesia

    Full Text Available These last few years, the name of soybeans soared as a source of biodiesel. Soy biodiesel is an alternative fuel produced from soybean oil. Soybean potential as an alternative renewable energy source because it is expected to have the highest energy content compared to other alternative fuels. Opportunities to develop biodiesel using soybean oil in Indonesia is quite large, considering the soybean is a commodity that is already known and widely cultivated almost in all over Indonesia. In addition, the use of soybean for biofuel feedstock is expected to motivate farmers to cultivate soybeans, so their use is not limited to non-energy raw materials. Soybean varieties that have a high oil content as well as high yield is a source of major biodiesel feedstock. From 73 soybean varieties that have been released in Indonesia, has an average oil content of 18%. Varieties with high oil content can be used as raw material for biodiesel. Research on the use of soy as an ingredient of energy crops (biodiesel have been carried out. In fact, soybean oil is the vegetable oil feedstock for most of the biodiesel being produced in the United States today. With the potential for soybean crops in Indonesia, both in terms of availability of land and varieties, the use of soybean oil for biofuel development in Indonesia is the flagship prospective materials for bio fuel substitute than other plants in the future.

    2010-01-01

    Advanced ceramic integration technologies dramatically impact the energy landscape due to wide scale application of ceramics in all aspects of alternative energy production, storage, distribution, conservation, and efficiency. Examples include fuel cells, thermoelectrics, photovoltaics, gas turbine propulsion systems, distribution and transmission systems based on superconductors, nuclear power generation and waste disposal. Ceramic integration technologies play a key role in fabrication and manufacturing of large and complex shaped parts with multifunctional properties. However, the development of robust and reliable integrated systems with optimum performance requires the understanding of many thermochemical and thermomechanical factors, particularly for high temperature applications. In this presentation, various needs, challenges, and opportunities in design, fabrication, and testing of integrated similar (ceramic ceramic) and dissimilar (ceramic metal) material www.nasa.gov 45 ceramic-ceramic-systems have been discussed. Experimental results for bonding and integration of SiC based Micro-Electro-Mechanical-Systems (MEMS) LDI fuel injector and advanced ceramics and composites for gas turbine applications are presented.

    Eisenhaure, D. B.; Bliamptis, T. E.; Downer, J. R.; Heinemann, P. C.

    Potential benefits regarding fuel savings, necessary technology, and evaluation criteria for the development of flywheel-hybrid vehicles are examined. A case study is quoted in which adoption of flywheel-hybrid vehicles in a taxi fleet would result in an increase of 10 mpg average to 32 mpg. Two proposed systems are described, one involving direct engine power to the flywheel and the second regenerating the flywheel from braking energy through a continuously variable transmission. Fuel consumption characteristics are considered the ultimate determinant in the choice of configuration, while material properties and housing shape determine the flywheel speed range. Vehicle losses are characterized and it is expected that a flywheel at 12,000 rpm will experience less than one hp average parasitic power loss. Flywheel storage is suitable for smaller engines because larger engines dominate the power train mass. Areas considered important for further investigation include reliability of an engine run near maximum torque, noise and vibration associated with flywheel operation, start up delays, compatibility of driver controls, integration of normal with regenerative braking systems, and, most importantly, the continuously variable transmission.

    Although most freshwater resources are used in agriculture, a greater amount of energy is consumed per unit of water supply for urban areas. Therefore, efforts to reduce the carbon footprint of water in cities, including the energy embedded within household uses, can be an order of magnitude larger than for other water uses. This characteristic of urban water systems creates a promising opportunity to reduce global greenhouse gas emissions, particularly given rapidly growing urbanization worldwide. Based on a previous Water-Energy-CO2 emissions model for household water end uses, this research introduces a probabilistic two-stage optimization model considering technical and behavioral decision variables to obtain the most economical strategies to minimize household water and water-related energy bills given both water and energy price shocks. Results show that adoption rates to reduce energy intensive appliances increase significantly, resulting in an overall 20% growth in indoor water conservation if household dwellers include the energy cost of their water use. To analyze the consequences on a utility-scale, we develop an hourly water-energy model based on data from East Bay Municipal Utility District in California, including the residential consumption, obtaining that water end uses accounts for roughly 90% of total water-related energy, but the 10% that is managed by the utility is worth over 12 million annually. Once the entire end-use + utility model is completed, several demand-side management conservation strategies were simulated for the city of San Ramon. In this smaller water district, roughly 5% of total EBMUD water use, we found that the optimal household strategies can reduce total GHG emissions by 4% and utility's energy cost over 70,000/yr. Especially interesting from the utility perspective could be the "smoothing" of water use peaks by avoiding daytime irrigation that among other benefits might reduce utility energy costs by 0.5% according to our

  20. Renewable energy and conservation measures for non-residential buildings

    Science.gov (United States)

    Grossman, Andrew James

    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.

  1. The origin of the energy-momentum conservation law

    Chubykalo, Andrew E.; Espinoza, Augusto; Kosyakov, B. P.

    2017-09-01

    The interplay between the action-reaction principle and the energy-momentum conservation law is revealed by the examples of the Maxwell-Lorentz and Yang-Mills-Wong theories, and general relativity. These two statements are shown to be equivalent in the sense that both hold or fail together. Their mutual agreement is demonstrated most clearly in the self-interaction problem by taking account of the rearrangement of degrees of freedom appearing in the action of the Maxwell-Lorentz and Yang-Mills-Wong theories. The failure of energy-momentum conservation in general relativity is attributed to the fact that this theory allows solutions having nontrivial topologies. The total energy and momentum of a system with nontrivial topological content prove to be ambiguous, coordinatization-dependent quantities. For example, the energy of a Schwarzschild black hole may take any positive value greater than, or equal to, the mass of the body whose collapse is responsible for forming this black hole. We draw the analogy to the paradoxial Banach-Tarski theorem; the measure becomes a poorly defined concept if initial three-dimensional bounded sets are rearranged in topologically nontrivial ways through the action of free non-Abelian isometry groups.

    This bibliography is a compilation of reports on the cost and energy savings of conservation and renewable energy applications throughout the United States. It is part of an overall effort to inform utilities of technological developments in conservation and renewable energy technologies and so aid utilities in their planning process to determine the most effective and economic combination of capital investments to meet customer needs. Department of Energy assessments of the applications, current costs and cost goals for the various technologies included in this bibliography are presented. These assessments are based on analyses performed by or for the respective DOE Program Offices. The results are sensitive to a number of variables and assumptions; however, the estimates presented are considered representative. These assessments are presented, followed by some conclusions regarding the potential role of the conservation and renewable energy alternative. The approach used to classify the bibliographic citations and abstracts is outlined.

    2012-01-01

    Relationships between measures of household energy use behavior and household characteristics are estimated using a unique dataset of approximately 5000 households in 10 EU countries and Norway. Family age-composition patterns are found to have a distinct impact on household energy use behavior. Households with young children are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy savings for environmental reasons. By contrast, households with a high share of elderly members place more importance on financial savings, and have lower levels of technology adoption, energy conservation practice use, and knowledge about household energy use. Education levels also matter, with higher levels associated with energy-efficient technology adoption and energy conservation practice use. Similarly, university education increases the stated importance of energy savings for greenhouse gas reductions and decreases the stated importance for financial reasons. Education impacts also vary greatly across survey countries and there is some evidence of an Eastern–Western European divide with respect to attitudes towards energy savings. These cross-country differences highlight the need to balance a common EU energy-efficiency policy framework with flexibility for country specific policies to address unique constraints to energy-efficient technology and conservation practice adoption. - Highlights: ► Household energy use behavior is explored with data from 11 European countries. ► Household age structure and education influence household energy use behavior and attitudes. ► Significant country differences in household energy use behavior exist. ► The EU needs to balance a common energy-efficiency policy framework with country specific policies.

  4. Energy, momentum and angular momentum conservations in de Sitter gravity

    In de Sitter (dS) gravity, where gravity is a gauge field introduced to realize the local dS invariance of the matter field, two kinds of conservation laws are derived. The first kind is a differential equation for a dS-covariant current, which unites the canonical energy-momentum (EM) and angular momentum (AM) tensors. The second kind presents a dS-invariant current which is conserved in the sense that its torsion-free divergence vanishes. The dS-invariant current unites the total (matter plus gravity) EM and AM currents. It is well known that the AM current contains an inherent part, called the spin current. Here it is shown that the EM tensor also contains an inherent part, which might be observed by its contribution to the deviation of the dust particle’s world line from a geodesic. All the results are compared to the ordinary Lorentz gravity. (paper)

    2008-01-01

    The chemical and energy industries are transforming as they adjust to the new era of high-priced petroleum and severe global warming. As a result of the transformation, engineering challenges and investment opportunities abound. Rapid evolution and fast growth are expected in cathode and anode materials as well as polymeric electrolytes for vehicular batteries and in high-performance polymer-ceramic composites for wind turbines, fuel-efficient aircraft, and lighter and safer cars. Unique process-engineering opportunities exist in sand-oil, coal, and possibly also shale liquefaction to produce transportation fuel; and also in genetic engineering of photosynthesizing plants and other organisms for their processing into high-performance biodegradable polymers and high-value-added environmentally friendly chemicals. Also, research on the feasibility of mitigation of global warming through enhancement of CO(2) uptake by the southern oceans by fertilization with trace amounts of iron is progressing. Because chemical engineers are uniquely well trained in mathematical modeling of mass transport, flow, and mixing, and also in cost analysis, they are likely to join the oceanographers and marine biologists in this important endeavor.

    Highlights: • Improving DSM program impacts by targeting high energy users. • DSM energy savings potential hinges on pre-participation performance. • Targeting can benefit different utilities and energy efficiency programs. • Overall performance can be improved by up to 250% via targeting strategies. - Abstract: Electric utilities, government agencies, and private interests in the US have committed and continue to invest substantial resources – including billions of dollars of financial capital – in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. While most of these programs are deemed to be cost effective, and therefore in the public interest, opportunities exist to improve cost effectiveness by targeting programs to those customers with the greatest potential for energy savings. This article details an analysis of three DSM programs offered by three Florida municipal electric utilities to explore such opportunities. First, we estimate programs’ energy savings impacts; second, we measure and compare energy savings across subgroups of program participants as determined by their pre-intervention energy performance, and third, we explore potential changes in program impacts that might be realized by targeting specific customers for participation in the DSM programs. All three programs resulted in statistically significant average (per-participant) energy savings, yet average savings varied widely, with the customers who performed best (i.e., most efficient) before the intervention saving the least energy and those who performed worst (i.e., least efficient) before the intervention saving the most. Assessment of alternative program participation scenarios with varying levels of customer targeting suggests that program impacts could be increased by as much as 80% for a professional energy audit program, just over 100% for a high-efficiency heat pump upgrade program, and nearly 250% for an attic insulation

    1983-11-01

    This report provides a technical description of the methodology and the results of a two year effort to collect field data on the performance of passive solar and energy conserving houses in California. Sixty-three passive solar houses were visited and several hours were spent with the homeowner obtaining building details, management procedures, architectural plans, photographs, and at least a year of billing data. With this information thermal performance parameters were calculated for each of the houses. Eleven of the above sixty-three Class C sites (nine passive solar and two energy conserving houses) were instrumented and monitored using the SERI Class B methodology as a guideline. Continuous data were collected for one year using up to 18 different sensors to measure temperatures, electric power, insolation, and the status of fans, gas burners, and moveable insulation. In addition careful one time measurements were made to determine the loss coefficient, infiltration rate, and furnace efficiency. Analysis of this data giving comfort conditions maintained and energy uses for a complete heating and cooling season for each of the houses is presented.

    Science.gov (United States)

    The primary objectives of the Caribbean Tourist Facilities (CTF) project were to develop and publish materials and conduct workshops on solar energy and conservation technologies that would directly address the needs and interests of tourist facilities in the Caribbean basin. Past contacts with the Caribbean and US tourist industries indicated that decision-makers remained unconvinced that renewable technologies could have a significant impact on development and operation costs or that renewable energy products and services suited their needs. In order to assure that the materials and programs developed were responsive to the Caribbean tourist industry and U.S. conservation and renewable energy industries, marketing research with potential end users and the organizations and associations that serve those users was included as an underlying task in the project. The tasks outlined in the CTF Statement of Work included conference planning, gathering of field data, development of educational materials, and conduct of workshop(s). In addition to providing a chronicle of the fulfillment of those tasks, this final report includes suggestions for distributing the documents developed during the project, venues for future workshops, and other technology transfer and market influence strategies.

  15. Retrofit energy conservation in residential buildings in southern California

    Turner, R. H.; Birur, G. C.; Daksla, C.

    1982-01-01

    The common energy conservation techniques (ECTs) that can be retrofit-installed into residential buildings are surveyed. The quantity of saved energy for heating and cooling attributable to each ECT is evaluated for three common modes of heating: natural gas heating at 60/therm; heating via heat pump at $1.20/therm; and electric resistance heating at $2.40/therm. In every case, a life cycle cost comparison is made between the long term revenue due to energy conservation and a safe and conventional alternative investment that might be available to the prudent homeowner. The comparison between investment in an ECT and the alternative investment is brought into perspective using the life cycle payback period and an economic Figure of Merit (FOM). The FOM allows for relative ranking between candidate ECTs. Because the entire spectrum of winter heating climates in California is surveyed, the decision maker can determine whether or not a considered ECT is recommended in a given climate, and under what conditions an ECT investment becomes attractive.

    In countries where the demand and supply gap of electricity is huge and the people are forced to endure increasing hours of load shedding, unnecessary consumption of electricity makes matters even worse. So the importance and need for electricity conservation increases exponentially. This paper outlines a step towards the conservation of energy in general and electricity in particular by employing efficient Building Automation technique. It should be noted that by careful designing and implementation of the Building Automation System, up to 30% to 40% of energy consumption can be reduced, which makes a huge difference for energy saving. In this study above mentioned concept is verified by performing experiment on a prototype experimental room and by implementing efficient building automation technique. For the sake of this efficient automation, Programmable Logic Controller (PLC) is employed as a main controller, monitoring various system parameters and controlling appliances as per required. The hardware test run and experimental findings further clarifies and proved the concept. The added advantage of this project is that it can be implemented to both small and medium level domestic homes thus greatly reducing the overall unnecessary load on the Utility provider.

    A survey of the standard of energy research in the American Literature on consumer behaviour is given. After the discussion of the importance of consumer research for energy conservation the difficulties on determining ''energy conservation behaviour'' are described. Moreover, the study compiles past American Literature that has tried to explain energy conservation behaviour. A further chapter analyzes measures of influencing the consumer energy conservation behaviour carried out so far in the United States and Canada. Finally, still open problems in future American energy conservation research in the field of consumer behaviour are demonstrated.

    Born-Oppenheimer molecular dynamics simulations with long-term conservation of the total energy and a computational cost that scales linearly with system size have been obtained simultaneously. Linear scaling with a low pre-factor is achieved using density matrix purification with sparse matrix algebra and a numerical threshold on matrix elements. The extended Lagrangian Born-Oppenheimer molecular dynamics formalism [A. M. N. Niklasson, Phys. Rev. Lett. 100, 123004 (2008)] yields microcanonical trajectories with the approximate forces obtained from the linear scaling method that exhibit no systematic drift over hundreds of picoseconds and which are indistinguishable from trajectories computed using exact forces.

    An energy conservation law is derived for fields generated by random, statistically stationary, scalar sources of any state of coherence. It is shown that correlation-induced spectral changes are in strict agreement with this law and that, basic to the understanding of such changes, is a distinction that must be made between the spectrum of a source and the spectrum of the field that the source generates. This distinction, which is obviously relevant for spectroscopy, does not appear to have been previously recognized. copyright 1996 The American Physical Society

    2002-01-01

    In the competitive industrial environment it is essential that cost of the product is kept at the minimum possible. Energy conservation is an important aspect in achieving this as energy is one of the key recourses for growth and survival of industry. The process of heavy water production being very complex and energy intensive, Heavy Water board has given a focussed attention for initiating various measures for reducing the specific energy consumption in all the plants. The initiative resulted in substantial reduction in specific energy consumption and brought in savings in cost. The cumulative reduction of specific energy consumption has been over 30% over the last seven years and the total savings for the last three years on account of the same has been about Rs. 190 crore. The paper describes the strategies adopted in the heavy water plants for effecting the above achievements. The paper covers the details of some of the energy saving schemes carried out at different heavy water plants through case studies. The case studies of schemes implemented at HWPs are general in nature and is applicable for any other industry. The case studies cover the modifications with re-optimisation of the process parameters, improvements effected in utility units like refrigeration and cooling water systems, improvements in captive power plant cycle and improved recycle scheme for water leading to reduced consumptions. The paper also mentions the innovative ammonia absorption refrigeration with improved coefficient of performance and HWB's efforts in development of the system as an integrated unit of the ammonia water deuterium exchange process for heavy water production. HWB also has taken up R and D on various other schemes for improvements in energy consumption for future activities covering utilisation of low grade energy for generation of refrigeration. (author)

  7. Quasilocal energy and conserved charges derived from the gravitational action

    International Nuclear Information System (INIS)

    Brown, J.D.; York, J.W. Jr.

    1993-01-01

    The quasilocal energy of gravitational and matter fields in a spatially bounded region is obtained by employing a Hamilton-Jacobi analysis of the action functional. First, a surface stress-energy-momentum tensor is defined by the functional derivative of the action with respect to the three-metric on 3 B, the history of the system's boundary. Energy surface density, momentum surface density, and spatial stress are defined by projecting the surface stress tensor normally and tangentially to a family of spacelike two-surfaces that foliate 3 B. The integral of the energy surface density over such a two-surface B is the quasilocal energy associated with a spacelike three-surface Σ whose orthogonal intersection with 3 B is the boundary B. The resulting expression for quasilocal energy is given in terms of the total mean curvature of the spatial boundary B as a surface embedded in Σ. The quasilocal energy is also the value of the Hamiltonian that generates unit magnitude proper-time translations on 3 B in the timelike direction orthogonal to B. Conserved charges such as angular momentum are defined using the surface stress tensor and Killing vector fields on 3 B. For spacetimes that are asymptotically flat in spacelike directions, the quasilocal energy and angular momentum defined here agree with the results of Arnowitt, Deser, and Misner in the limit that the boundary tends to spatial infinity. For spherically symmetric spacetimes, it is shown that the quasilocal energy has the correct Newtonian limit, and includes a negative contribution due to gravitational binding

  9. Developing sustainable energy policies for electrical energy conservation in Saudi Arabia

    2006-01-01

    Towards the end of 1998, the Saudi Arabian electricity sector embarked upon a major restructuring program. One of the aims of the program is to achieve sustainable performance. Although progress has been made, a number of challenges remain, including high demand growth, low generation capacity reserve margins, inefficient energy use, absence of time-of-use tariffs, and the need for large capital investments to meet current and future expansion. Electrical energy consumption in Saudi Arabia increased sharply during the last two decades due to rapid economic development and the absence of energy conservation measures. Peak loads reached nearly 24GW in 2001-25 times their 1975 level-and are expected to approach 60GW by 2023. The total investment needed to meet this demand may exceed $90 billion. Consequently, there is an urgent need to develop energy conservation policies for sustainable development. Current sustainable policies, particularly those pertaining to energy conservation, led to peak load savings of more than 871MW in 2001, mainly as a result of collaborations between the Ministry of Water and Electricity and the Saudi Electricity Company. In the long term, however, unless sustainable energy policies are developed at a national level, such efforts will be largely ineffective. To address this, policies and programs are being developed for public awareness, energy regulation and legislation, and energy information and programming. If energy conservation is taken into account, the forecast demand can be reduced by 5-10%. This is equivalent to 3-6GW of additional capacity, which represents a possible $1.5-3.0 billion saving over the next 20 years. Typically, investment in energy efficiency is 1% of utility sales revenues, which for a country like Saudi Arabia could be $15-60 million p.a. If only savings on air conditioning are considered, the return on investment is equivalent to 400-500MW p.a. of generating capacity-a saving of up to $0.25 billion p.a. In this

If only savings on air conditioning are considered, the return on investment is equivalent to 400-500MW p.a. of generating capacity-a saving of up to $0.25 billion p.a. In this

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

  12. Stable schemes for dissipative particle dynamics with conserved energy

    Energy Technology Data Exchange (ETDEWEB)

    Stoltz, Gabriel, E-mail: stoltz@cermics.enpc.fr

    2017-07-01

    This article presents a new numerical scheme for the discretization of dissipative particle dynamics with conserved energy. The key idea is to reduce elementary pairwise stochastic dynamics (either fluctuation/dissipation or thermal conduction) to effective single-variable dynamics, and to approximate the solution of these dynamics with one step of a Metropolis–Hastings algorithm. This ensures by construction that no negative internal energies are encountered during the simulation, and hence allows to increase the admissible timesteps to integrate the dynamics, even for systems with small heat capacities. Stability is only limited by the Hamiltonian part of the dynamics, which suggests resorting to multiple timestep strategies where the stochastic part is integrated less frequently than the Hamiltonian one.

  13. Energy conservation by hyperfiltration: food industry background literature survey

    Energy Technology Data Exchange (ETDEWEB)

    1980-04-15

    The application of hyperfiltration to selected food product streams and food processing wastewaters for energy conservation was examined. This literature survey had led to the following conclusions: no research has been conducted in the food industry using membranes with hot process streams due to the temperature limitation (< 40/sup 0/C) of the typically studied cellulose acetate membranes; based on the bench-scale research reviewed, concentration of fruit and vegetable juices with membranes appears to be technically feasible; pretreatment and product recovery research was conducted with membranes on citrus peel oil, potato processing and brine wastewaters and wheys. The experiments demonstrated that these applications are feasible; many of the problems that have been identified with membranes are associated with either the suspended solids or the high osmotic pressure and viscosity of many foods; research using dynamic membranes has been conducted with various effluents, at temperatures to approx. 100/sup 0/C, at pressures to 1200 psi and with suspended solids to approx. 2%; and, the dynamic membrane is being prototype tested by NASA for high temperature processing of shower water. The literature review substantiates potential for dynamic membrane on porous stainless tubes to process a number of hot process and effluent streams in the food processing industry. Hot water for recycle and product concentrations are major areas with potential for economic application. The two plants involved in the first phase of the project should be reviewed to identify potential energy conservation applications. As many as possible of the conservation applications should be tested during the screening phase at each site. The most promising applications at each site should be evaluated more intensively to establish engineering estimates of the economics of this technology for the canned fruit and vegetable segment of the food industry.

    Maas, C.

    2009-03-15

    Energy is needed to deliver water to, within and from communities to remove contaminants from water and wastewater, and to heat water in homes. The interconnections between water and energy are referred to as the water-energy nexus. Large volumes of water are needed to generate energy, notably to power turbines, to cool thermal or nuclear energy plants, and to extract oil from tar sands. At the same time, large amounts of energy are needed to pump, treat, heat and distribute water for urban, industrial and agricultural use and to collect and treat the resulting wastewater. The two sides of the water-energy nexus are generating new research and policy proposals to address the challenges of climate change, energy security and increasing water scarcity. This report demonstrated that a large untapped opportunity exists for water conservation to reduce energy, municipal costs and greenhouse gas (GHG) emissions. The water-energy research in this study was based on a Soft Path for Water approach that incorporated facets of water demand management while moving beyond a short-term focus on cost-benefit criteria to examine how the services currently provided by water can be delivered to meet the need for economic, social and ecological sustainability. Although the research was conducted using data for municipalities in Ontario, the report is relevant to the rest of Canada and much of North America. Water conservation strategies included water efficiency measures such as high efficiency toilets and washing machines, as well as water saving measures such as xeriscaping and rainwater harvesting. The objectives of the study were to quantify the energy use associated with each component of the urban water use cycle and to determine the potential for energy and GHG emissions reductions associated with water conservation strategies. This report provided an overview of energy inputs needed for water provision. It outlined the methodology used to achieve the project objectives and

    1982-07-01

    The benefits and applications of five irrigation technologies are explored: mobile drop-tube irrigation, computerized scheduling, reduced-pressure center pivots, well design and development, and automated gated-pipe systems. Perhaps the most promising of the new irrigation technologies is the low-energy, precision-application (LEPA) system. This mobile system used one-half the energy of conventional sprinkler systems and distributes water with greater efficiency through a series of low-pressure drop tubes suspended above the crop. Computerized methods of irrigation scheduling have been developed to help farmers conserve water and energy. Special computer programs determine when a crop needs water and how much to apply for optimal plant growth, thus preventing the unnecessary costs of pumping more water than the crop needs. Field test results show that replacing traditional scheduling methods of irrigation with computerized scheduling can reduce energy and water use by as much as 35%. The irrigation industry is actively promoting reduced-pressure water application methods, particularly for center-pivot systems. Reduced-pressure systems expend less energy but produce the same crop yields as conventional high-pressure systems, as long as excessive water runoff does not occur. If well design and development techniques are applied when a well is drilled into an unconsolidated acquifer, the well's life expectancy, as well as its operating efficiency, can increase, the later by as much as 40%.

    2012-05-01

    Maximizing the optical network unit’s (ONU) sleep time is an effective approach for achieving maximum energy conservation in green Ethernet passive optical networks (EPONs). While overlapping downstream and upstream ONU transmissions can maximize the ONU sleep time, it jeopardizes the quality of service (QoS) performance of the network, especially for downstream traffic in case the overlapping is based on the upstream time slot. In this paper, we study the downstream traffic performance in green EPONs under the limited service discipline and the upstream-based overlapped time window. Specifically, we first derive the expected mean packet delay, and then present a closed-form expression of the ONU sleep time, setting identical upstream/downstream transmission cycle times based on a maximum downstream traffic delay re-quirement. With the proposed system model, we present a novel downstream bandwidth allocation scheme for energy conservation in green EPONs. Simulation results verify the proposed model and highlight the advantages of our scheme over conventional approaches.

    The rapid growth of energy use, worldwide, hfs raised concerns over problems of energy supply and exhaustion of energy resources. Most of the developed countries are implementing building energy regulations such as energy standards, codes etc., to reduce building energy consumption. The position of developing countries with respect to energy regulations implementation and enforcement is either poorly documented or not documented at all. In addition, there is a lack of consistent data, which makes it difficult to understand the underlying changes that affect energy regulation implementation in developing countries. In that respect, this paper investigates the progress of building energy regulations in developing countries and its implication for energy conservation and efficiency. The present status of building energy regulations in 60 developing countries around the world was analysed through a survey of building energy regulations using online survey. The study revealed the present progress made on building energy regulations in relation to implementation, development and compliance; at the same time the study recommends possible solutions to the barriers facing building energy regulation implementation in the developing world. - Research Highlights: →Progress and implications of energy regulations in developing countries. →Investigation assessed the progress made on energy regulations using online survey. →Energy regulation activities is progressively increasing in developing countries. →The study identified 25 developing countries without energy regulatory standards. →The study shows relationship between energy regulation and energy consumption.

    Among various matters which make up the earth's crust, the thermal conductivity of coal, oil, and oil-gas, which are formed over a long period of geological time, is extremely low. This is significant to prevent transferring the internal heat of the earth to the thermal insulation of the surface, cooling the surface of the earth, stimulating biological evolution, and maintaining natural ecological balance as well. Fossil energy is thermal insulating layer in the earth's crust. Just like the function of the thermal isolation of subcutaneous fatty tissue under the dermis of human skin, it keeps the internal heat within the organism so it won't be transferred to the skin's surface and be lost maintaining body temperature at low temperatures. Coal, oil, oil-gas, and fat belong to the same hydrocarbons, and the functions of their thermal insulation are exactly the same. That is to say, coal, oil, and oil-gas are just like the earth's "subcutaneous fatty tissue" and objectively formed the insulation protection on earth's surface. This paper argues that the human large-scale extraction of fossil energy leads to damage of the earth's crust heat-resistant sealing, increasing terrestrial heat flow, or the heat flow as it is called, transferring the internal heat of the earth to Earth's surface excessively, and causing geotemperature and sea temperature to rise, thus giving rise to global warming. The reason for climate warming is not due to the expansion of greenhouse gases but to the wide exploitation of fossil energy, which destroyed the heat insulation of the earth's crust, making more heat from the interior of the earth be released to the atmosphere. Based on the energy conservation principle, the measurement of the increase of the average global temperature that was caused by the increase of terrestrial heat flow since the Industrial Revolution is consistent with practical data. This paper illustrates "pathogenesis" of climate change using medical knowledge. The

    This report provides an overview of the activities and achievements of the executive branch of the Federal Government in implementing the energy conservation requirements and provisions of section 381 of the Energy Policy and Conservation Act (EPCA) of 1975 (Public Law 94-163). The report describes Federal actions to develop procurement policies that promote energy conservation and efficiency, develop a Federal 10-Year Buildings Energy Conservation Plan, develop responsible public education and information programs, encourage energy conservation and energy efficiency, and promote vanpooling and carpooling arrangements. About half of the Nation's energy is used in our homes and automobiles. Another 48 percent is used by State and local governments, business and insutry, in providing needed goods and services. The Federal Government is the Nation's largest energy user, accouting for 2.2 percent of the total national energy used in 1977. This energy is used by nearly 6 million people in more than 400 thousand buildings and in the operation of more than 600 thousand vehicles. While energy conservation and energy efficiency measures alone cannot solve our immediate problems, they are an essential part of our transition to an era of scarce and expensive energy supplies.

    To examine the consumer behavior sector of energy demand patterns in Canada, this report undertook to identify major groupings of households based on energy consumption profiles and energy values, to relate these groupings to situational and demographic factors, and to initiate a comparative analysis of the receptivity of the major groupings to alternative energy conservation policy proposals. Data were collected from household surveys and energy suppliers. Householders were asked about their attitudes to energy conservation and energy policy, and profiles of energy consumption patterns of typical households were identified. To aid in evaluating the research, households were classified according to their levels of in-home energy consumption and automobile gasoline consumption. The findings indicated a range of lifestyles highly interrelated in terms of levels of energy consumption, ownership of energy-consuming products, knowledge and concern for energy issues, willingness to cut back energy consumption, and preferences for alternative conservation policies. The study has shown that most consumers are not very aware of the energy problem, do not see conservation as a serious need, and are unlikely to accept major policy interventions that result in major changes in energy supplies and current lifestyles. A number of recommendations are made as to policies, and their possible impact, to conserve household energy. 8 refs. 11 tabs.

  9. Opportunities and obstacles for rangeland conservation in San Diego County, California, USA

    2017-03-01

    Full Text Available Working landscapes such as rangelands are increasingly recognized as having high conservation value, providing a variety of ecosystem services, including food, fiber, habitat, recreation, open space, carbon storage, and water, in addition to a broad range of social benefits. However, conversion of rangelands to other land uses has been prevalent throughout the western United States, leading to greater attention in the conservation community to the importance of collaborating with private landowners. The level of interest in collaborative conservation among private landowners and the types of conservation programs they choose to participate in depend on the social, economic, and environmental context. We used GIS analysis and interviews with ranchers to evaluate rangeland conversion and participation in conservation programs among ranchers in San Diego County, California, USA, which is part of a biodiversity hotspot with high plant species richness and a large number of endemic and rare species. We found that > 25% of rangelands were converted to other uses, primarily urbanization, over the past 25 years while the area of public rangeland increased by 9%. Interviews revealed that ranchers in San Diego County have had limited involvement with most conservation programs, and a critical factor for nonparticipation was providing programs access to private land, along with other issues related to trust and social values. Among ranchers who had participated in conservation programs, the payment level and the agency or organization administering the program were key factors. Our results provide insight into factors influencing whether and when ranchers are likely to participate in conservation initiatives and illustrate that private and public land conservation are strongly linked and would be more effective if the two strategies were better integrated.

    The primary goal of this study is to investigate the effectiveness of behavioral interventions aimed at promoting energy conservation by consumers. It is argued that energy conservation has many advantages over other energy policy options, especially with respect to sociopolitical, economic, technical, safety and environmental considerations. Theories are discussed which deal with micromotives behind individual energy consumption and their macroconsequences. Antecedent and consequence behavioral interventions (information/education, prompting, modeling, feedback, self-monitoring, reinforcement/punishment) for promoting energy conservation by consumers are analyzed, and an extensive review is presented of behavioral experiments conducted in this area. Discussed is how the field experiment, which was conducted in five cities in the Netherlands with appr. 400 subjects, has been implemented. Hypotheses are tested regarding belief structures with respect to energy conservation. Provided are data about the absolute and relative effectiveness of energy conservation information, biweekly and monthly feedback, and self-monitoring in encouraging consumers to conserve energy. Hypotheses are tested about cognitive aspects related to responsiveness to behavioral interventions and attitude change toward energy conservation. Conclusions are presented and some energy policy recommendations and directions for future research are formulated. (J.C.R.)

    1990-01-01

    The determination of the full societal costs of energy usage must incorporate estimates of the environmental effects, or externalities, of energy production and delivery. An externality is any cost or benefit that is not reflected in the price paid by a utility or its customers for energy produced or consumed. The potential variety and scope of externality analyses are discussed. Four methods of externality valuation are briefly discussed to highlight the uses, strengths and pitfalls of each method. The use of pollutants' relative potency, polling of experts, direct estimation of costs, and implied valuation, are compared. The authors preferred method of valuation for near-term energy supply decisions, implied valuation, is discussed in detail. The distinguishing feature of the implied valuation technique is its use of the cost of control, rather than the direct cost of emissions. Only the most expensive required control measure is relevant to valuation of the external effects. The difficulties in applying implied valuation, such as the definition of the margin, the multiple effects of pollutants and the imperfect nature of the regulatory system, are also considered. The effect of environmental externalities on the benefits of conservation are summarized

    2001-05-31

    Electric motor systems are widely used in China to power fans, pumps, blowers, air compressors, refrigeration compressors, conveyers, machinery, and many other types of equipment. Overall, electric motor systems consume more than 600 billion kWh annually, accounting for more than 50 percent of China's electricity use. There are large opportunities to improve the efficiency of motor systems. Electric motors in China are approximately 2-4 percent less efficient on average than motors in the U.S. and Canada. Fans and pumps in China are approximately 3-5 percent less efficient than in developed countries. Even more importantly, motors, fans, pumps, air compressors and other motor-driven equipment are frequently applied with little attention to system efficiency. More optimized design, including appropriate sizing and use of speed control strategies, can reduce energy use by 20 percent or more in many applications. Unfortunately, few Chinese enterprises use or even know about these energy-saving practices. Opportunities for motor system improvements are probably greater in China than in the U.S. In order to begin capturing these savings, China is establishing a China Motor Systems Energy Conservation Program. Elements of this program include work to develop minimum efficiency standards for motors, a voluntary ''green motor'' labeling program for high-efficiency motors, efforts to develop and promote motor system management guidelines, and a training, technical assistance and financing program to promote optimization of key motor systems.

Positioned in urban centres and transport networks, these unique buildings were originally constructed in the 19th century to ensure better food distribution in growing European cities, then copied to other territories such as Egypt.  We argue that leaving market halls, with their large spanning structures and indoor open space, for dilapidation is a lost opportunity for sustaining community engagement, and educating the public on the original sustainability, neighbourhood regeneration and cultural thinking that underpinned these buildings. The proposed framework extends current sustainable ‘heritage conservation frameworks’ beyond concepts of adding renewable energy technologies, recycling and sustainable goods movement,  to ‘sustaining liveability and social inclusion’. We argue that market halls offer the opportunities to merge the daily activities of buying and selling food with creating local creative economies such as culinary art exhibitions, and culinary schools. The paper consists of two parts: the first discusses the historical urban context of market halls in Cairo; the second proposes a sustainable heritage conservation model for market halls.

    With increasing awareness of energy conservation and environmental protection, the Arab World is moving to further improve energy conversion efficiency. The equivalent of over 2.7 MM bbl is being daily burnt to fuel the thermal power plants that represent 92% of the total Arab power generation. This adds up to close to one billion barrels annually. At a conservative 30$ per barrel, this represents a daily cost of over $81 Million. This paper will introduce two strategies with the ultimate objective to cut-off up to half of the current fuel consumption. Firstly, Cogeneration Technology is able to improve thermal efficiency from the current average of less than 25% to up to 80%. Just 1% improvement in power plant thermal efficiency represents 3 million $/day in fuel cost savings. In addition, a well-designed and operated cogeneration plant will: - Reduce unfriendly emissions by burning less fuel as a result of higher thermal efficiency, - Increase the decentralization of electrical generation, - Improve the reliability of electricity supply. As an example, the Kingdom of Saudi Arabia's experience of implementing cogeneration will be presented, in particular within its hydrocarbon facilities and desalination plants. This will include the existing facilities and the planned and on-going projects. Secondly, by interconnecting the power networks of all the adjacent Arab countries, the following benefits could be reached: - Reduce generation reserves and enhance the system reliability, - Improve the economic efficiency of the electricity power systems, - Provide power exchange and strengthen the supply reliability, - Adopt technological development and use the best modern technologies. At least two factors plead for this direction. On one hand, the four-hour time zone difference from Eastern to Western Arab World makes it easy to exchange power. On the other hand, this will help to reduce the reserve capacity and save on corresponding Capital investment, fuel, and O and M

    An air conditioner has been retrofitted by application of an optimized fan in combination with an EC motor (brushless dc-motor). Attention is paid to the difference between an AC- and and EC motor, between free-running and spiral housing fans, between direct or indirect-driven, and between forward-bended and backward-bended blades. By means of equations and diagrams the realized energy conservation is visualized. [Dutch] De renovatie van een luchtbehandelingskast wordt besproken. Door de toepassing van ventilatoren met een geoptimaliseerde waaier in combinatie met een EC-motor (borstelloze gelijkstroommotor) wordt een substantiele energiebesparing gerealiseerd. Er wordt op verschillende aspecten ingegaan. Onder meer het verschil tussen een AC- en EC-motor, tussen vrijlopende en slakkenhuisventilatoren, tussen direct- of indirect-gedreven schoepen en tussen voorwaarts- of achterwaartsgebogen schoepen. Aan de hand van vergelijkingen en diagrammen wordt de energiewinst zichtbaar gemaakt.
