    In total, about 650 million DKK yearly is used in Denmark for energy conservation incentives - 300 million DKK for the electric utilities' energy saving activities, 250 million DKK for energy labelling of buildings, and 100 million DKK for electric power saving activities. The present evaluation of all the Danish energy conservation activities has been performed based on the energy political agreements of 10 June 2005 and of 21 February 2008. The objective is to strengthen and develop the Danish energy savings efforts based on the experiences with the present activities and incentives. The evaluation is performed through data compilations from interviews with selected target groups and from questionnaires to the electric utilities. Furthermore, a statistical analysis was performed of the development of the energy consumption in eight countries, and information of other countries' energy conservation activities was compiled. The energy saving activities and incentives that are evaluated are: Taxes and CO{sub 2} quotas, the electric utilities' activities, energy labelling of buildings, the Electric Power Saving Trust, building codes, labelling of appliances, energy conservation requirements for public workplaces, agreement with the energy intensive industry, and the Energy Conservation Fund. The evaluation of these nine energy saving activities and incentives shows, that they were established over several years as answers to different energy political requirements. The coordination of these activities is in some cases insufficient. At the same time, the implementation of EU's CO{sub 2} quota system is a challenge to the other incentives. For example, the quota system has increased the incentive for electric power savings because of a higher power price but on the other hand it does not result in CO{sub 2} reductions within the actual quota period. Several of the savings systems seem to have too little focus on a systematic documentation of their

Finally, the achieved effects of the present Danish energy saving efforts are presented. (ln)

  3. Promoting household energy conservation

    International Nuclear Information System (INIS)

    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

    @@ May 20 is World Metrology Day and the theme of this year is "Metrology and Energy Conservation." Energy is not only a vital issue for China, but also for the world. In order to implement Proposal of the CPC Central Committee on the 11th Five-Year Program for National Economic and Social Development, the government bulletin of 5th Plenary Session of the 16th CPC Central Committee announced that "there shall be marked improvement on resource utilization; the energy consumption for unit GDP shall cut 20%, water consumption of unit industrial added value drop 30%... and the recycle ratio of industrial solid wastes shall raise by 60%." These are key targets of economic development during the 11th five-year program. To make full use of metrology for energy conservation and energy utilization, the competent metrology department of Chinese Goyernment advanced metrology program in light of China's energy status.

  5. Energy audit for energy conservation

    International Nuclear Information System (INIS)

    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.

  6. 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. PMID:12295818

  7. 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.

  8. Building for energy conservation

    Energy Technology Data Exchange (ETDEWEB)

    Burberry, P.

    1978-01-01

    Ways in which buildings may be designed to increase thermal efficiency are discussed, giving first of all examples of thermal design in relation to climate. How the building itself may be designed to take advantage of solar energy and the ways in which heat loss takes place are described; the effect of design variables such as siting, volume, and insulation is shown. The book also reviews the development of thermal regulations for health and comfort and, more recently, energy conservation. It discusses the possitilities and difficulties of legislation for energy saving. The UK regulations are given in detail together with descriptions of the FHA and ASHRAE recommendations for the USA and the lastest Scandinavian norms. The author argues that no significant cost need be involved in many of the aspects of thermal design, e.g., shape and fenestration; and that these factors should automatically be taken into account by designers. Even existing buildings can be adapted in various respects to save energy consumption. The book concludes with an explanation of calculation methods for U-values, heat loss, plant sizing, seasonal heat requirements, and other procedures, amply illustrated with tables and graphs.

  9. Supply Curves of Conserved Energy

    Energy Technology Data Exchange (ETDEWEB)

    Meier, Alan Kevin

    1982-05-01

    Supply curves of conserved energy provide an accounting framework that expresses the potential for energy conservation. The economic worthiness of a conservation measure is expressed in terms of the cost of conserved energy, and a measure is considered economical when the cost of conserved energy is less than the price of the energy it replaces. A supply curve of conserved energy is independent of energy prices; however, the economical reserves of conserved energy will depend on energy prices. Double-counting of energy savings and error propagation are common problems when estimating conservation potentials, but supply curves minimize these difficulties and make their consequences predictable. The sensitivity of the cost of conserved energy is examined, as are variations in the optimal investment strategy in response to changes in inputs. Guidelines are presented for predicting the consequences of such changes. The conservation supply curve concept can be applied to peak power, water, pollution, and other markets where consumers demand a service rather than a particular good.

  14. Foundry energy conservation workbook

    Energy Technology Data Exchange (ETDEWEB)

    1990-01-01

    The foundry industry is a significant user of energy, and therefore, a natural candidate for efforts to save energy and improve efficiency by both governmental agencies and technical/trade associations. These efforts are designed to both improve the national energy position and improve the industry's efficiency and profitability. Increased energy cost and the reduced availability of fossil fuels at certain times have provided the incentive to curb waste and to utilize purchased energy wisely. Energy costs now approach and sometimes exceed 10% of the sales dollar of many foundries. Although energy use by foundries has gradually decreased on a per/ton basis in recent years, the foundry industry must continue to find ways to utilize energy more efficiently. This workbook provides ways to achieve this goal.

    On the path to Fusion power, the construction of ITER is on-going, however there is not much progress in performance improvements of tokamaks in the last 15 years, Fig.1. One possible reason for this stagnation is the lack of innovations in physics and technology that could be implemented...... with this approach in which progress is expected mainly from the increase in the size of a Fusion device. Such innovations could be easier to test and use in much smaller (and so cheaper and quicker to build) compact Fusion devices. In this paper we propose a new path to Fusion energy based on a compact high field...

    International Nuclear Information System (INIS)

    The promotion of energy economy and efficiency is recognized as the single most cost-effective and least controversial component of any strategy of matching energy demand and supply with resource and environmental constraints. Historically such efficiency gains are not out of reach for the industrialized market economy countries, but are unlikely to be reached under present conditions by developing countries and economics in transition. The aim of the work was to analyze the main characteristics of United Kingdom, France, Japan, Canada, Australia and Denmark energy conservation integrated programs

    1990-01-01

    Binary logit and bivariate probit models were used to investigate the investment behavior of farmers relative to two energy-conserving assets, heat-recovery systems and precoolers. The bivariate probit procedure was useful in correcting for self-selectivity bias. Holdout samples and cross-validation procedures were used to develop true model statistics. Farm size, educational level of the operator, and the type of milking system in use were the important factors influencing investment behavior.

    Deotale, Nilesh T.; Kalbande, Dhananjay R.; Mishra, Akassh A.

    2011-10-01

    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.

  20. Personality traits and energy conservation

    International Nuclear Information System (INIS)

    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

  1. Psychological dimensions of Energy Conservation

    Directory of Open Access Journals (Sweden)

    Tonello, Graciela

    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.

  4. On energy conservation in extended magnetohydrodynamics

    International Nuclear Information System (INIS)

    A systematic study of energy conservation for extended magnetohydrodynamic models that include Hall terms and electron inertia is performed. It is observed that commonly used models do not conserve energy in the ideal limit, i.e., when viscosity and resistivity are neglected. In particular, a term in the momentum equation that is often neglected is seen to be needed for conservation of energy

  5. Quantum wormhole and energy conservation

    International Nuclear Information System (INIS)

    We present an exact solution of a traversable wormhole in the semiclassical scheme without introducing any unnatural matter as exotic matter, which is a source of the wormhole, and study the back-reaction of the infalling matter on the wormhole. When a static traversable wormhole is used to transport matter from our universe to an other universe, we show that it satisfies the energy conservation law with an appropriate boundary condition. It means that the non-static wormhole perturbed by the in going f-matter field in an intermediate region finally returns to its original static state, and that the energy difference between the in going and the radiated energy causes a change in the radius of the throat of the final static wormhole as compared with that of the initial wormhole.

  6. Energy Conservation In Computational Grids

    Directory of Open Access Journals (Sweden)

    Monika Yadav

    2012-07-01

    Full Text Available With the increasing development of high-speed wide-area networks and powerful though low cost computational resources, grid computing has emerged as an attractive computing paradigm.With recent advances in computing, the scope of grid computing has been expanded to include mobile and pervasive devices. Grids have become one of the highest consumers of energy. High performance computing is achieved at the cost of energy consumption. Increasing the performance of computer systems requires increasing number of resources which leads to higher power consumption and it creates negative impact on environment. Idle sites in grid are direct sources of energy waste. Saving energy causes twodirect advantages: financial and environmental cost reduction and sustainability. With the Grid becoming a viable high-performance alternative to the traditional supercomputing environment, various aspects of Grid resource utilization which can help in energy conservation are gaining significance. In this paper we explore the possibility of reduction in energy consumption of a grid of heterogeneous computers by making use of different power states of cpu.

  12. Equity implications of utility energy conservation programs

    Energy Technology Data Exchange (ETDEWEB)

    Sutherland, R.J.

    1994-03-15

    This paper uses the Residential Energy Consumption Survey undertaken by the Energy Information Administration in 1990 to estimate the statistical association between household income and participation in electric utility energy conservation programs and the association between participation and the electricity consumption. The results indicate that utility rebates, energy audits, load management programs and other conservation measures tend to be undertaken at greater frequency by high income households than by low income households. Participants in conservation programs tend to occupy relatively new and energy efficient residences and undertake conservation measures other than utility programs, which suggests that utility sponsored programs are substitutes for other conservation investments. Electricity consumption during 1990 is not significantly less for households participating in utility programs than for nonparticipants, which also implies that utility conservation programs are displacing other conservation investments. Apparently, utility programs are not avoiding costs of new construction and instead are transferring wealth, particularly to high income participating households.

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

  7. Energy-momentum conservation and Lipkin's zilch

    OpenAIRE

    Lashkari-Ghouchani, H.; Alizadeh, M. H.

    2014-01-01

    As Noether's theorem states any differentiable symmetry of the action of a physical system has a corresponding conservation law. Lipkin introduced the conservation laws of zilches. But the corresponding symmetries are yet to be determined. Here we find a method to determine those symmetries and by direct calculations express the zilch tensor's relation to current-density for $n$-dimensional Minkowski space-time. Also, we extend this method to calculate symmetries of conservation of energy-mom...

    1993-12-31

    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 Directory facilitates quick access to DOE offices responsible for conservation and renewable energy activities. Because several offices in DOE may have responsibility for various phases of a technology or service (i.e., research, development, demonstration, commercialization, information, education, etc.) the Directory lists the key contacts from the various phases by category. The Directory is organized in five main categories plus an index and relevant appendices. The categories are: revewable energy technologies (thermal and electric solar, wind energy systems, small scale hydroelectric, biomass, ocean systems); complementary technologies (appropriate technology, advanced engine design, cogeneration, energy storage, total energy systems); conservation technologies (buildings and community systems, transportation, industrial and agricultural energy conservation, state and local programs); environment; and support services (information, outreach, education, small business support, basic research, data and analysis, publication, films, Solar Energy Research Institute, regional offices laboratories, and information centers).

  11. Italian energy conservation laws: Implementation problems

    International Nuclear Information System (INIS)

    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

  14. Energy conservation in India: a profile

    International Nuclear Information System (INIS)

    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

  16. Energy efficiency and conservation in Mexico

    Energy Technology Data Exchange (ETDEWEB)

    Guzman, O.M.; Yunez Naude, A.; Wionczek, M.S.

    1987-01-01

    Comparing the degree of efficiency in energy production and the uses to which energy resources are allocated in Mexico with that in other countries, this book addresses three basic questions: What are the major reasons for differences in energy efficiency between industrial economies and a newly industrializing country like Mexico. To what extent is energy conservation possible in the Mexican economy. And what are the social and economic benefits of more efficient use and conservation of energy in comparison with their costs. Using the history and operations of two state-owned energy agencies, PEMEX and the Federal Electricity Commission, as case studies, the contributors explore the patterns of energy use in all major sectors of the economy and discuss the prospects for energy-saving policies between the mid-1980s and the end of the century.

  17. Analysis of sectoral energy conservation in Malaysia

    International Nuclear Information System (INIS)

    The electrical energy consumption in Malaysia has increased sharply in the past few years, and modern energy efficient technologies are desperately needed for the national energy policy. This article presents a comprehensive picture of the current status of energy consumption and various energy conservation options viable for Malaysian environment. A detailed survey is made to assess the consumption pattern and the existing techniques for energy efficiency. Based on the survey, the feasibility of improving the available systems and adopting new programs in different sectors is investigated. The study reveals the fact that the energy conservation policy of the country has been fairly improved in the last ten years. However the country has to pay more attention to this area and make urgent measures to adopt more energy efficient technologies in various sectors.

    An energy conservation law is described, expressing the increase in mass-energy of a general black hole in terms of the energy densities of the infalling matter and gravitational radiation. For a growing black hole, this first law of black-hole dynamics is equivalent to an equation of Ashtekar & Krishnan, but the new integral and differential forms are regular in the limit where the black hole ceases to grow. An effective gravitational-radiation energy tensor is obtained, providing measures o...

  19. Energy Conservation Equations of Motion

    CERN Document Server

    Vinokurov, Nikolay A

    2015-01-01

    A conventional derivation of motion equations in mechanics and field equations in field theory is based on the principle of least action with a proper Lagrangian. With a time-independent Lagrangian, a function of coordinates and velocities that is called energy is constant. This paper presents an alternative approach, namely derivation of a general form of equations of motion that keep the system energy, expressed as a function of generalized coordinates and corresponding velocities, constant. These are Lagrange equations with addition of gyroscopic forces. The important fact, that the energy is defined as the function on the tangent bundle of configuration manifold, is used explicitly for the derivation. The Lagrangian is derived from a known energy function. A development of generalized Hamilton and Lagrange equations without the use of variational principles is proposed. The use of new technique is applied to derivation of some equations.

  20. Social psychological aspects of energy conservation

    Science.gov (United States)

    Aronson, Elliot; Yates, Suzanne

    1985-11-01

    Although some increases in the adoption of energy-efficient practices have been noted, only a small fraction of the potential savings are being realized, perhaps because human behavior is too complex for existing economic models. The rational-economic model is able to predict behavior in many situations, but it has limitations. To design effective public policy, the social, cognitive, and personal forces, that in addition to the economic realities define the situation, must be understood. This chapter examines one aspect of current energy conservation policy, the home energy audit program mandated by the Residential Conservation Service, and attempts to show how existing social psychological research might be beneficially applied.

    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)

  2. Energy conservation and substitution: refining the objectives

    Energy Technology Data Exchange (ETDEWEB)

    Foley, G.

    1981-06-01

    Energy conservation is not a precisely defined concept; consequently, there is a considerable confusion about how to implement it or predict its effects. Reducing dependence on oil should be the central objective of energy policy, but this may not be furthered by generalized conservation strategies. Achieving a reduction in oil dependence requires a balanced policy of conservation and substitution. As governments have reacted against oil price rises and the subsequent inflationary effects with a swing towards monetarism and a harsher reliance upon market forces, the role of oil has become even more important. Reliance upon these policies has not eased the oil blockage upon economic activity; it has made it worse and made the task of providing alternatives to oil more difficult. Market forces have had a wedging, rather than a freeing, effect upon the pattern of energy supply. But the point is that conservation, on its own, does not create the momentum away from oil which is essential. The immediate objective is not to achieve a reduction in the consumption of energy as an end in itself, but as part of a liberation from dependence upon oil. Energy conservation needs to be seen as a servant of this wider objective. 21 references.

  3. Energy conserving dehumidification of greenhouses

    NARCIS (Netherlands)

    2014-01-01

    As greenhouses become better insulated and increasingly airtight, the humidity of the inside air rises easily and may become unfavourably high. Therefore, most greenhouses frequently open their vents to remove the moisture excess. When heated, opening the vents will increase the energy consumption.

  4. Energy savings potential from energy-conserving irrigation systems

    Energy Technology Data Exchange (ETDEWEB)

    Wilfert, G.L.; Patton, W.P.; Harrer, B.J.; Clark, M.A.

    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.

    1994-12-31

    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.

    1981-12-01

    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.

  13. Energy prices and the promotion of energy conservation. A background study for energy conservation programme

    International Nuclear Information System (INIS)

    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. Exploration of energy conservation opportunities through energy audit

    International Nuclear Information System (INIS)

    Developing countries like India, has to cater to 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 cost 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. (author). 2 refs., 12 tabs

    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.

    A series of Energy Conservation Indicators were developed for the Department of Energy to assist in the evaluation of current and proposed conservation strategies. As descriptive statistics that signify current conditions and trends related to efficiency of energy use, indicators provide a way of measuring, monitoring, or inferring actual responses by consumers in markets for energy services. Related sets of indicators are presented in some 40 one-page indicator summaries. Indicators are shown graphically, followed by several paragraphs that explain their derivation and highlight key findings. Indicators are classified according to broad end-use sectors: Aggregate (economy), Residential, Commercial, Industrial, Transportation and Electric Utilities. In most cases annual time series information is presented covering the period 1960 through 1981.

  20. Energy conserving effects of dividing wall column☆

    2015-01-01

    The energy-conserving performance of dividing wal column (DWC) is discussed in this paper. The heat transfer through the dividing wall is considered and the results are compared with that of common heat insulation dividing wall column (HIDWC). Based on the thermodynamic analysis of heat transfer dividing wall column (HTDWC) and HIDWC, both computer simulation and experiments are employed to analyze the energy-conserving situation. Mixtures of n-hexane, n-heptane and n-octane are chosen as the example for separation. The results show that the energy consumption of HTDWC is 50.3%less than that of conventional distillation column, while it is 46.4% less than that of HIDWC. It indicates that DWC is efficient on separating three-component mixtures and HTDWC can save more energy than HIDWC. Thus it is necessary to consider the heat transfer while applying DWC to industry.

  2. Energy conservation. Federal shared energy savings contracting

    International Nuclear Information System (INIS)

    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

  3. Energy conservation for dynamical black holes.

    Science.gov (United States)

    Hayward, Sean A

    2004-12-17

    An energy conservation law is described, expressing the increase in mass-energy of a general black hole in terms of the energy densities of the infalling matter and gravitational radiation. This first law of black-hole dynamics describes how a black hole grows and is regular in the limit where it ceases to grow. An effective gravitational-radiation energy tensor is obtained, providing measures of both ingoing and outgoing, transverse and longitudinal gravitational radiation on and near a black hole. Corresponding energy-tensor forms of the first law involve a preferred time vector which plays the role of a stationary Killing vector. Identifying an energy flux, vanishing if and only if the horizon is null, allows a division into energy supply and work terms. The energy supply can be expressed in terms of area increase and a newly defined surface gravity, yielding a Gibbs-like equation. PMID:15697889

    In this address, the author states that although DOE-sponsored energy conservation programs slowed between 1986-1990, the trend is expected to be reversed because of more aggressive government and utility incentive programs. The federal government, through technology R and D, technology transfer, industry partnerships and appropriate market conditioning activities, is playing a substantial role in the achievement of greater energy efficiency for the nation

    The general position of France and its energy conservation objectives; the action taken by the government to stimulate this policy; and government cooperation with industrial circles and the action of industry itself are discussed. It is observed that the potential for future energy savings are smaller in France than in other countries because consumptions are already down to minimal levels. Consumption patterns in France are illustrated. (MCW)

  10. Energy-conserving development regulations: current practice

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-01

    Almost every aspect of land development has an effect on energy use, from minute architectural details to broad considerations of urban density. Energy-efficiency depends in part on how development is planned and carried out. Conventional development regulations, such as zoning ordinances and subdivision regulations, can be adapted in many ways to promote energy conservation at the community level. This report is about energy-efficient site and neighborhood design. It examines recent experiences of local governments that have adopted new development regulations or amended existing ones to promote energy conservation, more efficient generation and distribution, or a switch to alternative, renewable sources. Although much has been written in recent years about saving energy through community design, actual experience in applying these new ideas is still limited. To date, most communities have focused their efforts on studying the problem, documenting consumption patterns, and writing reports and plans. Only a handful have amended their land-use controls for the express purpose of saving energy. This study identifies 13 of these pioneering communities, after undertaking a survey of over 1400 local, regional, and state planning agencies. It takes a look at their experiences, to learn what has been done, how well it has worked, and what problems have been encountered.

  11. Energy conservation by reducing process variability

    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)

  12. Dissipative or Conservative cosmology with dark energy ?

    2006-01-01

    All evolutional paths for all admissible initial conditions of FRW cosmological models with dissipative dust fluid (described by dark matter, baryonic matter and dark energy) are analysed using dynamical system approach. With that approach, one is able to see how generic the class of solutions leading to the desired property -- acceleration -- is. The theory of dynamical systems also offers a possibility of investigating all possible solutions and their stability with tools of Newtonian mechanics of a particle moving in 1D potential which is parametrised by the cosmological scale factor. We demonstrate that flat cosmology with bulk viscosity can be treated as a conservative system with a potential function of the Chaplygin gas type. We characterise the class of dark energy models that admit late time de Sitter attractor solution in terms of the potential function of corresponding conservative system. We argue that inclusion of dissipation effects makes the model more realistic because of its structural stabil...

    1982-05-01

    Multifamily housing project managers can reduce their energy costs from 30 to 60 percent by capitalizing on a variety of energy conservation opportunities (ECO's) identified in HUD research on the physical condition of public housing stock. This workbook prepares managers for this planning and for making individualized energy audits. It provides all the materials they need to proceed, including analysis sheets for calculating costs - benefit and payback periods for each of the 50 ECO's described. The ECO's listed all into four general categories: architectural improvements to the energy design of the building envelope; heating system ECO's to increase energy efficiency; secondary ECO's related to the domestic water supply, air conditioning systems, and central laundry equipment; and electric system ECO's reducing utility surcharges and increasing light bulb efficiency.

    1994-09-01

    The impetus at the national level to invest in energy conservation is quite strong and has long been reflected not only in official pronouncements, but also in the investments and organizational activities of the Chinese government. In the early 1980s the central government began a program of direct investments in industrial energy conservation that continues to the present. In addition, concurrently established governmental and quasi-governmental agencies have pursued conservation through administrative and educational measures. In Section 2 of this paper the authors outline the policies and institutions that supported China`s program of energy conservation investments in the Sixth and Seventh Five-Year Plans (FYPs) (1981--1985 and 1986--1990). In Section 3 they describe examples of the types of conservation projects pursued in four industrial subsectors: ferrous metals manufacturing; non-ferrous metals mining and manufacturing; chemicals manufacturing; and building materials manufacturing. Section 4 presents a simple methodology for comparing the costs of energy conservation to those of energy supply. Further discussion points out the applicability and limitations of this methodology to State Planning Commission published statistical material on the overall results of energy conservation investments. Though problematic, such analysis indicates that energy conservation investments were probably substantially cheaper than investments in equivalent energy supply would have been. They end with a discussion of some of the difficulties encountered in carrying out the conservation investment programs.

  18. HOSPITAL VENTILATION STANDARDS AND ENERGY CONSERVATION: A REVIEW OF GOVERNMENTAL AND PRIVATE AGENCY ENERGY CONSERVATION INITIATIVES

    Energy Technology Data Exchange (ETDEWEB)

    Banks, Robert S.; Rainer, David

    1980-03-01

    This report presents the results of a recent research project originally concerned with review of governmental initiatives for changes to hospital design and operation standards at both the federal and state levels. However. it quickly became apparent that concern with energy conservation was not impacting hospital environmental standards, especially at the state level, irrespective of the energy implications. Consequently, the study was redirected to consider all energy conservation initiatives directed toward design and operating practices unique to the hospital environment. The scope was limited to agency programs (i.e., not undertaken at the initiative of individual hospitals), applicable to non-federal public and private hospitals.

  1. Green Tribology Biomimetics, Energy Conservation and Sustainability

    CERN Document Server

    Bhushan, Bharat

    2012-01-01

    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.

  2. Opportunities for energy conservation through biotechnology

    Energy Technology Data Exchange (ETDEWEB)

    Young, J.K.; Griffin, E.A.; Russell, J.A.

    1984-11-01

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

  3. Energy conservation and energy decentralization: issues and prospects

    Energy Technology Data Exchange (ETDEWEB)

    Levine, M.D.; Craig, P.P.

    1980-01-01

    Views are presented of the seemingly paradoxical nature and irrationality of the energy system and the decisions that determine its evolution. An economic approach to energy decisions, while widely espoused and generally believed to be the underpinning of our system, appears not to be functioning in very-important areas. The result is enormous waste of economic and intangible resources to produce energy that could be effectively replaced by energy conservation at low costs. This inefficiency in the economic system is, in the author's judgment, far greater than is recognized either by the public or by experts. They feel it has led to an over-investment in centralized energy systems and has discouraged the use of decentralized systems that could contribute significantly in the near term to a lessening of our energy problems. There are some signs that the situation is changing, albeit rather slowly. High prices and the widespread recognition of the seriousness of our energy problems have contributed to an increasing involvement of individuals in energy decisions profoundly affecting their future. To achieve an evolution of the energy system in which decentralized technologies (and, in the near term, particularly technologies that improve the efficiency of energy use) play an important role, the government must act forcefully. This action needs to recognize and be responsive to the powerful discriminatory effect of the economic system, as it is presently constituted, against investments in energy conservation.

    We have presented views of the seemingly paradoxical nature and irrationality of the energy system and the decisions that determine its evolution. An economic approach to energy decisions, while widely espoused and generally believed to be the underpinning of our system. appears not to be functioning in very important areas. The result is enormous waste of economic and intangible resources to produce energy that could be effectively replaced by energy conservation at low costs. This inefficiency in the economic system is, in our judgment. far greater than is recognized either by the public or by 'experts.' It has led to an over-investment in centralized energy systems and has discouraged the use of decentralized systems that could contribute significantly in the near term to a lessening of our energy problems. There are some signs that the situation is changing. albeit rather slowly.

  5. 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

  10. Energy conservation attitudes, knowledge, and behaviors in science laboratories

    International Nuclear Information System (INIS)

    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.

  11. Conservation and energy efficiency plan 2006

    International Nuclear Information System (INIS)

    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

    Energy Technology Data Exchange (ETDEWEB)

    Gaines, L.L.; Wolsky, A.M.

    1979-12-01

    Scrap tires that are not recycled through retreading constitute a serious solid-waste problem, but also offer energy-conservation opportunities through their use as: (1) solid fuel (displaced energy = 15,000 Btu/lb or 35 kJ/g); (2) derived fuel and chemical feedstock (11,000 to 23,000 Btu/lb or 25 to 53.5 kJ/g); (3) virgin rubber compound substitute in traditional rubber products (34,000 to 40,000 Btu/lb or 79 to 93 kJ/g); and (4) asphalt additive for paving applications (90,000 Btu/lb or 210 kJ/g). Both the energy of the displaced fuel and material and the energy consumed preparing the tires for the above uses have been included, where possible, in these estimates. Also provided is a summary of the available data on the cost and requisite scale of operation for the various end use processes.

    1975-01-01

    A methodology for a systems approach display and assessment of the potential for energy conservation actions and the impacts of those actions was presented. The U.S. economy is divided into four sectors: energy industry, industry, residential/commercial and transportation. Each sector is assessed with respect to energy conservation actions and impacts. The four sectors are combined and three strategies for energy conservation actions for the combined sectors are assessed. The three strategies (national energy conservation, electrification and diversification) represent energy conservation actions for the near term (now to 1985), the mid term (1985 to 2000) and the far term (2000 and beyond). The assessment procedure includes input/output analysis to bridge the flows between the sectors, and net economics and net energetics as performance criteria for the conservation actions. Targets of opportunity for large net energy net energy savings and the application of technology to achieve these savings are discussed.

With that approach, one is able to see how generic the class of solutions leading to the desired property-acceleration-is. The theory of dynamical systems also offers a possibility of investigating all possible solutions and their stability with tools of Newtonian mechanics of a particle moving in a one-dimensional potential which is parameterized by the cosmological scale factor. We demonstrate that flat cosmology with bulk viscosity can be treated as a conservative system with a potential function of the Chaplygin gas type. We characterize the class of dark energy models that admit late time de Sitter attractor solution in terms of the potential function of corresponding conservative system. We argue that inclusion of dissipation effects makes the model more realistic because of its structural stability. We also confront viscous models with SNIa observations. The best fitted models are obtained by minimizing the χ2 function which is illustrated by residuals and χ2 levels in the space of model independent parameters. The general conclusion is that SNIa data supports the viscous model without the cosmological constant. The obtained values of χ2 statistic are comparable for both the viscous model and ΛCDM model. The Bayesian information criteria are used to compare the models with different power-law parameterization of viscous effects. Our result of this analysis shows that SNIa data supports viscous cosmology more than the ΛCDM model if the coefficient in viscosity parameterization is fixed. The Bayes factor is also used to obtain the posterior probability of the model

    This report describes the results of a project that examined what commercial banks could do on their own to encourage energy conservation in existing residences. The recommendations made herein reflect the present realities of both the commercial banking sector and the marketplace for energy conservation technology. These realities include three key points: (1) banks have limited intereat in promoting energy conservation; (2) the economics of their operations limit their opportunities for radical improvement in the terms that they can offer consumers; and (3) consumer demand for financing of energy conservation is derived, not primary. The report is organized in a question and answer format, including 10 questions dealing with observations about the marketplace for conservation programs; attitudes and operations; what banks are doing in energy conservation now; and finally issues relevant to the policymaker in DOE and in the banking industry.

    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.)

    Barnes, P.R.; Van Dyke, J.W.; McConnell, B.W.; Das, S.

    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.

  8. A new method for constructing total energy conservation algorithms

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    Based on a basic rule for the research on numerical methods which requires that the properties of the original problem should be preserved as much as possible under discretization, a new method for constructing total energy conservation algorithms is presented. By this method, all kinds of implicit schemes with energy conservation laws including many classical conservation schemes can be constructed from a kind of special function. Also, the concrete criterion for judging total energy conservation schemes is given. Numerical tests show that these new schemes are effective.

  9. 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.

  3. US energy conservation and efficiency policies: Challenges and opportunities

    International Nuclear Information System (INIS)

    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.

  7. Marketing: an approach to successful energy-conservation information programs

    Energy Technology Data Exchange (ETDEWEB)

    Hutton, R. B.; McNeill, D. L.

    1980-08-01

    This monograph shows how the adoption of a marketing approach can improve the quality of the development and delivery of energy-conservation programs. Several factors make the use of such a marketing approach to conservation particularly beneficial, namely: (1) goals of conservation programs can be quantified (e.g., specified amount of energy to be saved); in addition, intermediate effects necessary for program success are also measureable (e.g., knowledge, attitude change, etc); (2) there is an apparent and increasing need for conservation by different parts (or sectors) of the population; however, it is clear that the desire for conservation is not the same for all sectors; (3) conservation programs can be thought of in much the same way as products with benefits and costs; this necessitates an understanding of how the population makes conservation decisions so that the program can fit into that decision process; (4) the need to tailor programs to the needs of the population is heightened by the general competition for the consumer dollar; it is necessary to design and present programs in a way that the individual will view conservation as an attractive choice among many (e.g., bank savings, buying clothes, furniture, car, etc.); and (5) the population's response to, and need for conservation is constantly changing; consequently, it is important to realize that these changes may need to be reflected in the conservation programs themselves (both ongoing and new).

  8. A New Conserved Energy for Incompressible Navier-Stokes Equations

    OpenAIRE

    2010-01-01

    Pressure conditions in incompressible Navier-Stokes equations give rise to conservation of total energy. The energy rate getting into a volume is the same energy rate that gets out from it. Suitable choice of pressure counteracts energy disipation of viscosity term in such a way that total energy is preserved. As consequence, this prevents kinetic energy blow-up in a given volume of the fluid.

  11. Progressively safer, cheaper demolition of Fernald

    International Nuclear Information System (INIS)

    Fluor Fernald, Inc. has been progressively improving Decontamination and Dismantlement (D and D) at the Department of Energy's Fernald Environmental Management Project by applying new technologies and better methodologies to the work. Demolition issues existed in the past that necessitated new or improved solutions to maintain worker safety, protect the environment and accomplish the work in a cost effective manner. Lessons learned from D and D of 80 structures has led to a systematic approach, which can be implemented in various D and D arenas. When facility production was halted, hold-up material and process residues remained in the process piping and components. Over 500,000 pounds of material was removed by workers who completed the tasks two years ahead of schedule, $7 million under budget and with an excellent safety record. This success was the result of detailed planning and irdision of lessons learned as work progressed from facility to facility. Work sequences were developed that reduced airborne contamination. Demolition of structures has been performed at Fernald by carefully selected and qualified subcontractors. Asbestos and lead abatement, equipment, piping and conduit removal, and structural demolition have been completed to progressively higher performance specifications developed by Fluor Fernald based on lessons learned during execution. Safety continues to be the primary consideration in performing potentially hazardous work. Technologies such as hydraulic shears have been developed and used to keep workers away from danger. A new technology, ''Cool Suits,'' has been demonstrated to help prevent heat stress when anti-contamination clothing is required in elevated temperature working conditions. For tall structures, implosion technologies have been employed with progressively improved results, Several other new technologies have been evaluated by Fluor Fernald and applied by subcontractors. The improved technologies included the oxy-gas torch

    1977-09-01

    This study is an application of the modeling and demand projection capability existing at Brookhaven National Laboratory to specific options in energy conservation. Baseline energy demands are modified by introducing successively three sets of conservation options. The implementation of improved building standards and the use of co-generation in industry are analyzed in detail and constitute the body of this report. Two further sets of energy demands are presented that complete the view of a low energy use, ''conservation'' scenario. An introduction to the report covers the complexities in evaluating ''conservation'' in view of the ways it is inextricably linked to technology, prices, policy, and the mix of output in the economy. The term as used in this report is narrowly defined, and methodologies are suggested by which these other aspects listed can be studied in the future.

    Hendrickson, P.L.; Mohler, B.L.; Taylor, Z.T.; Lee, A.D.; Onisko, S.A.

    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.

  17. Energy conservation in industry: Technical feasibility and obstacles

    Energy Technology Data Exchange (ETDEWEB)

    Lazzarin, R. (Padua Univ. (Italy))

    A comparison of Italy's energy requirements with those of other industrialized countries reveals that, while this nation does not have a particularly burdensome energy demand, it is strongly dependent on foreign energy supplies, and thus must have recourse to energy conservation. This analysis of energy demand and energy conservation in Italy focusses on industrial trends witnessed over the last decade. Here, it is noted that energy conservation received attention early in the 1980's as energy prices increased - a trend which died, however, with this current span of relatively stable prices. Noted obstacles to vigorous energy conservation include: a strong tendency towards the use of conventional, proven technologies; difficulties in evaluating the benefits of innovative energy savings equipment alternatives due to oil price uncertainty; and the pronounced lack of sufficiently well trained energy managers. On the technical side, sound energy savings systems are coming on the market, e.g., heat pumps, cogeneration systems, etc., but marketing efforts for these products have yet to incorporate effective programs for information dissemination and operator training.

    Lewis, C.W. [Strathclyde Univ., Glasgow (United Kingdom); O`Beirne, P. [Cyanamid (United Kingdom) Ltd. (United Kingdom). Animal Health Div.

    1994-12-31

    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)

  2. Model code for energy conservation in new building construction

    1977-12-01

    In response to the recognized lack of existing consensus standards directed to the conservation of energy in building design and operation, the preparation and publication of such a standard was accomplished with the issuance of ASHRAE Standard 90-75 ''Energy Conservation in New Building Design,'' by the American Society of Heating, Refrigerating and Air-Conditioning Engineers, Inc., in 1975. This standard addressed itself to recommended practices for energy conservation, using both depletable and non-depletable sources. A model code for energy conservation in building construction has been developed, setting forth the minimum regulations found necessary to mandate such conservation. The code addresses itself to the administration, design criteria, systems elements, controls, service water heating and electrical distribution and use, both for depletable and non-depletable energy sources. The technical provisions of the document are based on ASHRAE 90-75 and it is intended for use by state and local building officials in the implementation of a statewide energy conservation program.

    The objectives of this study were to: identify government policies for reducing Canadian consumption of home heating fuel, electricity, and gasoline; assess probable effectiveness of different policy alternatives as a means of reducing consumer energy consumption; and measure the acceptability to Canadian consumers of the different policy alternatives. 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.

    Full Text Available Current energy conservation and emissions reduction strategies in iron and steel industry were reviewed. Since foundry industry is one of the major source of energy consumption and pollution emission (especially CO2, issues concerning energy-saving and emission-reduction have been raised by governments and the industry. Specialists from around the world carried out multidimensional analyses and evaluation on the potentials in energy conservation and emissions reduction in iron and steel industry, and proposed various kinds of analyzing models. The primary measures mainly focus on the targeted policies formulation and also on clean and high-efficient technologies development. The differences and similarities in energy conservation and emission reduction in foundry industry between China and other countries were discussed, while, the future development trend was also pointed out.

    1980-12-01

    Building Energy Performance Standards (BEPS) were mandated by the Energy Conservation Standards for New Buildings Act of 1976 (Title III of Energy Conservation and Production Act) to promote energy efficiency and the use of renewable resources in new buildings. The report analyzes alternative Federal strategies and their component policy instruments and recommends a strategy for achieving the goals of the Act. The concern is limited to space conditioning (heating, cooling, and lighting) and water heating. 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 then 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) 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. (MCW)

    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.

    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.

  1. Energy and other resource conservation within urbanizing areas

    Science.gov (United States)

    Rowe, Peter G.

    1982-05-01

    The reported research seeks to answer several questions regarding energy conservation within urbanizing areas. As a practical matter, to what extent can dependence upon exhaustible resources be reduced? Can these reductions be achieved without severely impairing social well-being and environmental quality? And, what seem to be the prevailing institutional constraints limiting energy conservation within urbanizing areas? The study area was the proposed “downtown” of The Woodlands, a new town north of Houston, Texas. Two plans were developed for this area. In one, no particular attempt was made to conserve energy (conventional plan), while in the other, energy conservation was a primary consideration (conservation plan). For both plans, estimates were made of energy consumption within buildings, in the transportation sector, and in the actual production of building materials themselves (embodied energy). In addition, economic and environmental analyses were performed, including investigation of other resource issues such as water supply, solid waste disposal, stormwater management, and atmospheric emissions. Alternative on-site power systems were also investigated. Within the bounds of economic feasibility and development practicality, it was found that application of energy-conserving methods could yield annual energy savings of as much as 23%, and reduce dependence on prime fuels by 30%. Adverse economic effects on consumers were found to be minimal and environmental quality could be sustained. The major institutional constraints appeared to be those associated with traditional property ownership and with the use of common property resources. The resistance to change of everyday practices in land development and building industries also seemed to constrain potential applications.

    At a time of concern for energy supplies and costs it is essential to examine the energy-conserving potential of once again using natural energy systems and patterns that exist on any site on which a building is to be or has been placed. This state-of-the-art study examines existing research and applications of land planning and design for energy-conservation purposes. It is organized around the basic principles of natural heating and cooling factors and the impact of site elements on human comfort, regional adaptation of these principles, steps in the site planning and design process, and energy-conservation options available in each of the steps. This is supplemented by an appendix and a bibliography of additional references. The principles of site planning and design for energy conservation deal with the impact of the sun and wind on natural elements and, conversely, ways in which landforms, water, and vegetation affect the impact of the sun and wind on limited sections of the earth. For instance, the sun is able to naturally warm certain slopes more than others, certain surface materials naturally accentuate the warmth of the sun, while certain naturally occurring elements, such as vegetation, block and control the sun. The wind moving over the earth's surface has certain natural directions, patterns, and characteristics. By recognizing these and by introducing or removing impediments it is possible to modify these patterns to provide natural ventilation and to conserve energy. Four commonly accepted regional divisions were utilized to illustrate the differing applications of these principles in the temperate, hot-humid, hot-arid, and cool regions of the continental U.S. The typical site planning or design process was superimposed over each region to illustrate the various energy conservation options possible, depending upon the precise decision made in each step in each region. 300 references.

    United States energy consumption has remained essentially constant at about 80 exajoules/year (75 quads/year) since the oil embargo of 1973-1974, while the GNP in constant dollars has increased by about 30%. This article will discuss the physics behind some of these improvements in end-use efficiency in such areas as: (i) buildings (scaling laws, ``free-heat,'' superinsulated houses, thermal storage in large buildings, off-peak cooling), (ii) solar energy (passive, photovoltaics), (iii) utility load management (``smart meters,'' capital recovery fees, voltage control), (iv) appliances (life-cycle costs, refrigerators), and (v) lighting (isotopic enhancement).

    The energy conservation is a general law of nature. In the classical physics, the energy W_{AB} of a conservative system {AB} that contains the objects A and B is equal to a sum of the positive energies W_A and W_B of the isolated objects A and B, W_{AB} = W_A+W_B. We show that the energy conservation does not exhibit the "classic law" if the physical objects are waves or they do have a wave nature of microscopic (quantum) objects.

    1980-01-01

    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)

    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.

  7. Energy conservation in distillation: a technology applications manual

    Energy Technology Data Exchange (ETDEWEB)

    1980-05-01

    Distillation is the most widely practiced technique for separating mixtures of chemical species, but it is an energy intensive process. A 10% reduction in distillation energy consumption would effect a significant savings. On a national basis this would be an annual savings of 200 trillion Btu, or the equivalent of 36.5 million barrels of oil per year. Technology to achieve these savings in distillation energy is available and measures are presented to assist process engineers in technical and economic analysis of the energy conservation measures most suitable for particular distillation applications. The manual catalogs all of the energy conservation options applicable to distillation and the options by the investment required; describes in detail the options having a significant potential to reduce distillation energy requirements economically; provides guidelines that will allow the plant engineer to quickly screen each option for his application; and provides short-cut calculation procedures for use in a preliminary economic analysis of promising options.

    1984-01-01

    The internal heat gains from solar radiation in two unoccupied isolated houses resulting from external climatic factors were recorded over a two year period at Oakpark Research Centre, Carlow, Ireland. Different recording regimes were undertaken with altered site characteristics mostly windbreaks. Using the monitored data, regression models for each regime were generated which related internal ambient temperature to the external climatic parameters. A model was developed to withstand the difficulties imposed by short monitoring periods and these regression models were used to predict internal temperatures for a standard reference year. Thus resulting energy saving for different site characteristics were estimated. The savings due to the erection of a windbreak were in the region of 5% to 10% and the savings accruing from the use of a standard low energy house was about 70% over a basic house. The possible implications of these savings for Ireland and Europe are outlined.

    Full Text Available Most of the HVAC system in home is running based on static control algorithm; based on fixed work schedules. In that old system energy became waste when home contains low or no people occupancy. In this paper we presented new dynamic approach of HVAC system control, by combined with pervasive computing. Pervasive computing can be defined as availability of centralized system and information anywhere and anytime. We achieved our target by using occupancy sensors for collecting home status. Initially our occupancy sensors collect human presence and current HVAC status details and stored in centralized system. Then based on our user defined threshold value the centralized system maintains the building's heating, cooling and air quality conditions by controlling HVAC devices. I.e. this system turned off HVAC systems when a home is unoccupied, or put the system into an energy saving sleep mode when persons are asleep.

    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.

  17. Energy literacy, awareness, and conservation behavior of residential households

    International Nuclear Information System (INIS)

    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

  11. Energy conservation in dissipative processes: Teacher expectations and strategies associated with imperceptible thermal energy

    CERN Document Server

    Daane, Abigail R; Vokos, Stamatis; Scherr, Rachel E

    2014-01-01

    Research has demonstrated that many students and some teachers do not consistently apply the conservation of energy principle when analyzing mechanical scenarios. In observing elementary and secondary teachers engaged in learning activities that require tracking and conserving energy, we find that challenges to energy conservation often arise in dissipative scenarios in which kinetic energy transforms into thermal energy (e.g., a ball rolls to a stop). We find that teachers expect that when they can see the motion associated with kinetic energy, they should be able to perceive the warmth associated with thermal energy. Their expectations are violated when the warmth produced is imperceptible. In these cases, teachers reject the idea that the kinetic energy transforms to thermal energy. Our observations suggest that apparent difficulties with energy conservation may have their roots in a strong and productive association between forms of energy and their perceptible indicators. We see teachers resolve these ch...

  12. Home retrofitting for energy conservation and solar considerations

    Energy Technology Data Exchange (ETDEWEB)

    1981-10-01

    This manual explains both the key concepts behind our need for and our impact on energy usage, as well as a nuts-and-bolts explanation of how to improve the energy efficiency of your home. By reviewing both the concepts and practices of energy conservation, the manual presents a comprehensive picture of how home energy use is effected by the inhabitants and by the structure itself. The manual begins with an explanation of why we are looking at energy, then proceeds to explain how the heat transfer occurs between houses and humans. Next is a chapter on energy audits and how to use them, followed by a comprehensive section on energy conservation actions to do now to reduce energy use. Conservation actions include low cost/no cost measures, schemes to reduce infiltration, how to increase insulation, and what to do with windows and doors, heating and heat distribution systems, and water heaters. Solar energy options are then briefly explained, as well as the all important issues of financing and tax credits. The manual concludes with a bibliography to direct the reader to more sources of information.

  13. A surface-scattering model satisfying energy conservation and reciprocity

    CERN Document Server

    Sasihithlu, Karthik; Hugonin, Jean-Paul; Greffet, Jean-Jacques

    2015-01-01

    In order for surface scattering models to be accurate they must necessarily satisfy energy conservation and reciprocity principles. Roughness scattering models based on Kirchoff's approximation or perturbation theory do not satisfy these criteria in all frequency ranges. Here we present a surface scattering model based on analysis of scattering from a layer of particles on top of a substrate in the dipole approximation which satisfies both energy conservation and reciprocity and is thus accurate in all frequency ranges. The model takes into account the absorption in the substrate induced by the particles but does not take into account the near-field interactions between the particles.

    Traces the history of thermal insulation technology and standards since the commercialization of the steam engine in the late 18th century. Reveals that the development of magnesium carbonate as an insulation, and use of asbestos fiber as a heat resistant reinforcing material marked the transition of the insulation industry from small entrepreneurs to large corporate organizations. Points out that many of the world's current insulation manufacturers marked their genesis in the 1890-1910 period. Emphasizes that when the energy crisis occurred, C-16 standards for residential, commercial, and industrial insulation materials, application methods, and performance evaluation were either already available or, in the case of cellulosic and foam-in-place insulations, quickly prepared. Reports that a subcommittee has been formed to translate government specifications for commercial grade insulations to ASTM format, as in accordance with OMB Circular A119 which promotes the use of voluntary consensus standards by government agencies.

  17. China’s Structural Energy Conservation: Analysis and Proposals

    Institute of Scientific and Technical Information of China (English)

    张雷; 黄园淅

    2008-01-01

    Given the increasing dependence of development on energy consumption, an understanding of the rules and trends of national energy consumption is required for boosting social energy conservation. By using two models -- the structural evolution energy consumption model and the structural evolution per-unit energy consumption model, this article attempts to make an international comparison of the industrial structure development versus energy consumption patterns in the United States, the United Kingdom, France, Germany, Japan, and India. The results of this analysis indicate that the dominance of secondary industry over the industrial structure evolution process noticeably accelerates national energy consumption at the initial stage of modernization. Subsequently, a slowdown in energy consumption as a result of industrial structure development yields effects as the diversification process speeds up. Under such influence, energy consumption per unit of GDP follows an inverted U-shaped curve from rise to decline. As one of the world’s major energy producers and consumers, China has long employed a one- sided sector development policy. Under the influence of this policy, national energy conservation endeavors have been inhibited by the rigidity in its industry structural evolution. Thus, in China, energy consumption per unit of GDP has remained at a high level.

  1. The conservation of light's energy, mass, and momentum

    Science.gov (United States)

    Mortenson, Juliana H. J.

    2011-09-01

    An advance in the foundations of quantum mechanics was presented at the previous "Nature of Light" meeting which brings new insights to the conservation of light's energy, mass and momentum. Those discoveries suggest that the "photon" is a time-based collection of sub-photonic elementary light particles. Incorporation of this new understanding into quantum mechanics has allowed the determination of universal constants for the energy, mass, and momentum of light. The energy constant for light is 6.626 X 10-34 J/osc, meaning the energy of a single oscillation of light is constant irrespective of the light's frequency or wavelength. Likewise, the mass and momentum of a single oscillation of light are constant, regardless of changes to either time or space. A realistic understanding of the conservation of energy, mass and momentum for both matter and light in a single conservation law is now possible. When a body with mass absorbs or emits light, its energy, mass and momentum change in quantized amounts according to the relationship: Δ E = Nh~ = Nm0c2 = Nρ0c where "N" is the number of oscillations absorbed absorbed or emitted by the body and h~, m0, and ρ0 are the constant energy, mass and momentum of an oscillation. Implications extend from general relativity and gravity to space sails and light driven nanomotors.

  2. Jersey City energy conservation demonstration program. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Newbold, R.F.

    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.

  3. Effects of energy conservation measures on the German labour market

    International Nuclear Information System (INIS)

    In these times of rising unemployment, the effects of energy-political measures on the labour market should be scrutinized thoroughly. In addition, the structural effects on the various branches of economy ought to be investigated as well. This contribution first discusses the interdependences between energy conservation measures and the national economy in general. It then proceeds to investigate the model approaches which may be employed for an empirical analysis of these mechanisms. The fourth section investigates the economic effects of energy conservaton from an aggregated point of view and presents the empirical results of a comprehensive study. This is followed by a presentation of the sectoral effects based on the same study. The contribution closes by taking stock of the political conclusion that can be drawn from these analyses for improving energy conservation concepts. (orig)

  13. Conservation Laws and Energy Budget in a Static Universe

    Science.gov (United States)

    Heymann, Yuri

    2016-10-01

    The universe is characterized by large concentrations of energy contained in small, dense areas such as galaxies, which radiate energy towards the surrounding space. However, no current theory balances the loss of energy of galaxies, a requirement for a conservative universe. This study is an investigation of the physics nature might use to maintain the energy differential between its dense parts and the vacuum. We propose time contraction as a principle to maintain this energy differential. Time contraction has the following effects: photons lose energy, while masses gain potential energy and lose kinetic energy. From the virial theorem, which applies to a system of bodies, we find that the net energy resulting from the gain in potential energy and the loss in kinetic energy remains unchanged, meaning that the orbitals of stars in galaxies remain unaffected by time contraction. However, each object in a galaxy has an internal potential energy leading to a surplus of energy within the object. This internal energy surplus should balance with the energy radiated at the level of a galaxy. We illustrate this principle with a calculation of the energy balance of the Milky Way.

  16. National Target of Energy conservation and Policy Measures

    Energy Technology Data Exchange (ETDEWEB)

    Shim, S.R. [Korea Energy Economics Institute, Euiwang (Korea)

    2001-12-01

    This study investigates impacts of energy saving policies on the national economy in Korea. An energy saving policy for a specific sector causes changes in energy consumption patterns of a target sector as well as the others. In addition to its positive bearing on energy consumption, such policy can change energy prices, output, employment, consumer price levels, and resources allocation in the economy. In this context, successful analyses of energy saving policies need to consider such interactions to develop and evaluate the best policy alternatives. Thus, this study employs a Korean computable general equilibrium model to analyze optimal energy saving targets, and corresponding programs for each sector in the economy. The R and D investment policy in the energy sector is the most effective one since it is projected to increase real GNP and GDP, decreasing energy consumption. The policy is accordingly considered as one of so-called no-regret policies. And, the policy is evaluated to be appropriate for the energy intensive industries and transportation sectors. The government loan program for energy efficiency improvement is also predicted to raise GNP although it may have a negative impact on trade balance. And, the policy is observed to be suitable for the transportation and household sectors. An energy saving effort with energy taxation is found to be cost-effective since its marginal cost of energy conservation is estimated to be much lower than about 80,000 won per ton of oil equivalent, the estimated benefit of energy conservation. It is recommended, however, that an additional energy tax be implemented with care, given the high level of existing energy taxes. The effectiveness of energy efficiency standards in the transportation, household, and commercial sectors varies depending on how prices of relevant energy using equipments and appliances change in response to the standards. Energy saving policies are adequately formulated and implemented for all the

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

    International Nuclear Information System (INIS)

    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

  18. Fuel conservation under rational expectations of the energy price evolution

    Energy Technology Data Exchange (ETDEWEB)

    1986-06-01

    It is supposed, that a consumer demands a 'service' rather than a commodity. This service can be generated from a durable and non-durable good, e.g., 'thermal comfort' is the product of two at least partially substitutable factors: fuel and capital (insulation, heating system). Now, the choice of an efficient fuel conservation programme requires that the consumers integrate the counteractions of the energy producers. This leads formally to a (differential) game situation, where it will be shown that the expansion of capital stock based on a myopic analysis may lead to a too large investment in fuel conservation.

This tendency cannot be explained in terms of cost developments or foreign-trade considerations. A positive explanation proposed focuses on demand-income-supply interaction. An analysis of a cross-country price-augmented modification of Engel Law, econometrically specified, indicates that the relative price offood is related positively to the supply of food items and negatively to that of non-food items. This finding is consistent with "agricultural price scissors", and also casts a different light on the nature of economic development and structural change.

    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)

  4. 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.

  5. Selecting appropriate energy efficiency indicators for the Thai Energy Conservation Promotion Programme. Final report

    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.

  6. Energy conservation in dissipative processes: Teacher expectations and strategies associated with imperceptible thermal energy

    Research has demonstrated that many students and some teachers do not consistently apply the conservation of energy principle when analyzing mechanical scenarios. In observing elementary and secondary teachers engaged in learning activities that require tracking and conserving energy, we find that challenges to energy conservation often arise in dissipative scenarios in which kinetic energy transforms into thermal energy (e.g., a ball rolls to a stop). We find that teachers expect that when they can see the motion associated with kinetic energy, they should be able to perceive the warmth associated with thermal energy. Their expectations are violated when the warmth produced is imperceptible. In these cases, teachers reject the idea that the kinetic energy transforms to thermal energy. Our observations suggest that apparent difficulties with energy conservation may have their roots in a strong and appropriate association between forms of energy and their perceptible indicators. We see teachers resolve these challenges by relating the original scenario to an exaggerated version in which the dissipated thermal energy is associated with perceptible warmth. Using these exaggerations, teachers infer that thermal energy is present to a lesser degree in the original scenario. They use this exaggeration strategy to track and conserve energy in dissipative scenarios.

    This note addresses the issue of energy conservation for the 2D Euler system with an L p -control on vorticity. We provide a direct argument, based on a mollification in physical space, to show that the energy of a weak solution is conserved if {ω = nabla × u in L^{3/2}}. An example of a 2D field in the class {ω in L^{3/2 - ɛ}} for any ɛ > 0, and {u in B^{1/3}_{3,∞}} (Onsager critical space, see Shvydkoy in Discr Contin Dyn Syst Ser S 3(3):473-496, 2010) is constructed with non-vanishing energy flux. This demonstrates sharpness of the kinematic argument, which does not differentiate between 2D and 3D, and requires Onsager's regularity control on the solution. Next, we show that for physically realizable solutions there is a mechanism preventing the anomalous dissipation in 2D that does not require such a control. Namely, we prove that any solution to the Euler equations produced via a vanishing viscosity limit from the Navier-Stokes equations, with {ω in L^p}, for p > 1, conserves energy.

  9. Conservation of reactive electromagnetic energy in reactive time

    CERN Document Server

    Kaiser, Gerald

    2015-01-01

    The complex Poynting theorem (CPT) is extended to a canonical time-scale domain $(t,s)$. Time-harmonic phasors are replaced by the positive-frequency parts of general fields, which extend analytically to complex time $t+is$, with $s>0$ interpreted as a time resolution scale. The real part of the extended CPT gives conservation in $t$ of a time-averaged field energy, and its imaginary part gives conservation in $s$ of a time-averaged reactive energy. In both cases, the averaging windows are determined by a Cauchy kernel of width $\\Delta t\\sim \\pm s$. This completes the time-harmonic CPT, whose imaginary part is generally supposed to be vaguely `related to' reactive energy without giving a conservation law, or even an expression, for the latter. The interpretation of $s$ as reactive time, tracking the leads and lags associated with stored capacitative and inductive energy, gives a simple explanation of the volt-ampere reactive (var) unit measuring reactive power: a var is simply one Joule per reactive second.

  10. 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.

    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.

  16. Energy conservation and energy prices: the Hungarian experience

    International Nuclear Information System (INIS)

    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.

    The Washington Energy Extension Service Finance Program was commissioned for the overall purpose of facilitating and assessing the development of energy-related loan policies by financial institutions. Explicit objectives of the project are to: identify financial problems of small energy consumers in the domestic installation of energy-saving technologies; identify the financial options currently available in the State of Washington; and in concert with the financial institutions of the state, develop and analyze recommended additional programs which will benefit both consumers and financial institutions. This final report of the WEES Finance Program extends the rate-of-return analysis to include the overall required rates of return necessary to justify various commercial bank functional activities; with judicious implementation, this methodology can be a substitute for the subjective risk-assessment techniques currently utilized in the commercial banking sector. This report also considers changes that have occurred in the development of financial options related to energy-conservation measures.

The fuel consumption structure has changed from coal-burning to natural gas or fuel oil. The following auditing procedures were followed according to Chinese national standards. These procedures include constituting an ordinance on energy management, strengthening the energy measurement and data statistical system, and improving production lines as well as energy-saving measures. Production scale expanded approximately twice during the period of audit. Comprehensive energy consumption was 2.58 ton coal equivalent (tce) at aqual in heat value (AHV refers to energy consumed to generate each kW h of electric power, each m{sup 3} of oxygen, nitrogen, hydrogen, or each kg of steam. The term of AHV provides a unification measurement criterion for fossil fuels consumed before the energy transformation.) account per 10,000 Yuan output value, and 2.17 tce at heat value equivalent (HVE) account. Comprehensive energy consumption per unit of product was 15.35 kg coal equivalent (kce) per weight box. The percentage of energy cost among total cost reduced from 51.19% in 2007 to 46.48% in 2008. Consequently, the comprehensive energy conversion level holds a leading position among peers in China. (author)

    We present high-order, energy conserving, continuum algorithms for the solution of gyrokinetic equations for use in edge turbulence simulations. The distribution function is evolved with a discontinuous Galerkin scheme, while the fields are evolved with a continuous finite-element method. These algorithms work for a general, possibly non-canonical, Poisson bracket operator and conserve energy exactly. Benchmark simulations with ETG turbulence in 3X/2V are shown, as well as initial applications of the algorithms to turbulence in a simplified SOL geometry. Sheath boundary conditions with recycling and secondary electron emission are implemented, and a Lenard-Bernstein collision operator is included. Extension of these algorithms to full Vlasov-Maxwell equations are presented. It is shown that with a particular choice of numerical fluxes the total (particle+field) energy is conserved. Algorithms are implemented in a flexible and open-source framework, Gkeyll, which also includes fluid models, allowing potential hybrid simulations of various plasma problems.

    1979-10-01

    Policy assessment of energy conservation strategies has tended to emphasize technological and economic costs, problems, and benefits. However, too narrow a focus may fail to delineate all the environmental and social impacts associated with the technology in question. In recognition of the importance of a balanced evaluation, a study was undertaken to identify local-level perceptions about environmental and social problems and opportunities associated with several energy conservation measures. These measures included building performance standards and retrofit; waste heat utilization; modifications in land use configurations and transportation modes; and electric utility demand management, and rate reform initiatives. The perceptions were identified by interviewing 55 officials, planners, and members of business and citizen groups in Erie, Philadelphia, and Harrisburg (the capital), Pennsylvania. Results of the study indicate that implementation of the energy conservation measures under investigation faces political, economic, and social barriers of varying dimensions. Major among these are the constraints felt to be imposed by a declining economy and the resulting concern with attracting and holding business and industry.

    2016-05-25

    Coarse-graining (CG) of complex molecules is a method to reach time scales that would be impossible to access through brute force molecular simulations. In this paper, we formulate a coarse-grained model for complex molecules using first principles caculations that ensures energy conservation. Each molecule is described in a coarse way by a thermal blob characterized by the position and momentum of the center of mass of the molecule, together with its internal energy as an additional degree of freedom. This level of description gives rise to an entropy-based framework instead of the usual one based on the configurational free energy (i.e. potential of mean force). The resulting dynamic equations, which account for an appropriate description of heat transfer at the coarse-grained level, have the structure of the dissipative particle dynamics with energy conservation (DPDE) model but with a clear microscopic underpinning. Under suitable approximations, we provide explicit microscopic expressions for each component (entropy, mean force, friction and conductivity coefficients) appearing in the coarse-grained model. These quantities can be computed directly using MD simulations. The proposed non-isothermal coarse-grained model is thermodynamically consistent and opens up a first principles CG strategy for the study of energy transport issues that are not accessible using current isothermal models.

    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.

  17. Evaporation of (quantum) black holes and energy conservation

    International Nuclear Information System (INIS)

    We consider Hawking radiation as due to a tunneling process in a black hole were quantum corrections, derived from Quantum Einstein Gravity, are taken into account. The consequent derivation, satisfying conservation laws, leads to a deviation from an exact thermal spectrum. This has consequences for the information loss paradox since the non-thermal radiation is shown to carry information out of the black hole. Under the appropriate approximation, a quantum corrected temperature is assigned to the black hole. The evolution of the quantum black hole as it evaporates is then described by taking into account the full implications of energy conservation as well as the backscattered radiation. It is shown that, as a critical mass of the order of Planck's mass is reached, the evaporation process decelerates abruptly while the black hole mass decays towards this critical mass

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

    Science.gov (United States)

    Lu, Jia-An

    2016-08-01

    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.

  19. 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.

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

    International Nuclear Information System (INIS)

    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

  1. Optimal residential water conservation strategies considering related energy in California

    Science.gov (United States)

    Escriva-Bou, Alvar; Lund, Jay R.; Pulido-Velazquez, Manuel

    2015-06-01

    Although most freshwater resources are used in agriculture, residential water use is a much more energy intensive user. Based on this, we analyze the increased willingness to adopt water conservation strategies if energy cost is included in the customers' utility function. Using a Water-Energy-CO2 emissions model for household water end uses and probability distribution functions for parameters affecting water and water-related energy use in 10 different locations in California, 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 and costs given both water and energy price shocks. Results can provide an upper bound of household savings for customers with well-behaved preferences, and show greater adoption rates to reduce energy intensive appliances when energy is accounted, resulting in an overall 24% reduction in indoor water use that represents a 30% reduction in water-related energy use and a 53% reduction in household water-related CO2 emissions. Previous use patterns and water and energy rate structures can affect greatly the potential benefits for customers and so their behavior. Given that water and energy are somewhat complementary goods for customers, we use results of the optimization to obtain own-price and cross-price elasticities of residential water use by simulating increases in water and energy prices. While the results are highly influenced by assumptions due to lack of empirical data, the method presented has no precedent in the literature and hopefully will stimulate the collection of additional relevant data.

  13. Pressurization test results: Bonneville Power Administration Energy Conservation Study

    Energy Technology Data Exchange (ETDEWEB)

    Krinkel, D.L.; Dickeroff, D.J.; Casey, J.; Grimsrud, D.T.

    1980-12-01

    Results are presented of air leakage measurements in 18 single-family detached houses at the Midway substation, Hanford, Washington, performed as part of the Bonneville Power Administration's Energy Conservation Study. The change in energy consumption following various retrofit strategies is compared. Air leakage was measured in each house with the fan pressurization technique, before and after the retrofits were installed. No significant change was found in infiltration rates in those houses receiving either no retrofits or insulation only; and average reduction of 17% in leakage area was found in the houses retrofitted with storm doors and windows. There appears to be great potential for further savings in energy use from reduced infiltration, and the study is being extended to investigate this.

  14. Technology Utilization House Study Report. [For Energy Conservation

    Science.gov (United States)

    1974-01-01

    The objectives of Project TECH are: (1) to construct a single family detached dwelling for demonstrating the application of advanced technology and minimizing the requirement for energy and utility services, and (2) to help influence future development in home construction by defining the interaction of integrated energy and water management systems with building configuration and construction materials. Components and methods expected to be cost effective over a 20 year span were studied. Emphasis was placed on the utilization of natural heating and cooling characteristics. Orientation and location of windows, landscaping, natural ventilation, and characteristics of the local climate and microclimate were intended to be used to best advantage. Energy conserving homes are most efficient when design for specific sites, therefore project TECH should not be considered a prototype design suitable for all locations. However, it does provide ideas and analytical methods which can be applied to some degree in all housing.

  15. Computer simulated building energy consumption for verification of energy conservation measures in network facilities

    Science.gov (United States)

    Plankey, B.

    1981-01-01

    A computer program called ECPVER (Energy Consumption Program - Verification) was developed to simulate all energy loads for any number of buildings. The program computes simulated daily, monthly, and yearly energy consumption which can be compared with actual meter readings for the same time period. Such comparison can lead to validation of the model under a variety of conditions, which allows it to be used to predict future energy saving due to energy conservation measures. Predicted energy saving can then be compared with actual saving to verify the effectiveness of those energy conservation changes. This verification procedure is planned to be an important advancement in the Deep Space Network Energy Project, which seeks to reduce energy cost and consumption at all DSN Deep Space Stations.

  16. Retrofit energy conservation in residential buildings in southern California

    Science.gov (United States)

    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.

  18. Innovations for competitiveness: European views on "better-faster-cheaper"

    Science.gov (United States)

    Atzei, A.; Groepper, P.; Novara, M.; Pseiner, K.

    1999-09-01

    The paper elaborates on " lessons learned" from two recent ESA workshops, one focussing on the role of Innovation in the competitiveness of the space sector and the second on technology and engineering aspects conducive to better, faster and cheaper space programmes. The paper focuses primarily on four major aspects, namely: a) the adaptations of industrial and public organisations to the global market needs; b) the understanding of the bottleneck factors limiting competitiveness; c) the trends toward new system architectures and new engineering and production methods; d) the understanding of the role of new technology in the future applications. Under the pressure of market forces and the influence of many global and regional players, applications of space systems and technology are becoming more and more competitive. It is well recognised that without major effort for innovation in industrial practices, organisations, R&D, marketing and financial approaches the European space sector will stagnate and loose its competence as well as its competitiveness. It is also recognised that a programme run according to the "better, faster, cheaper" philosophy relies on much closer integration of system design, development and verification, and draws heavily on a robust and comprehensive programme of technology development, which must run in parallel and off-line with respect to flight programmes. A company's innovation capabilities will determine its future competitive advantage (in time, cost, performance or value) and overall growth potential. Innovation must be a process that can be counted on to provide repetitive, sustainable, long-term performance improvements. As such, it needs not depend on great breakthroughs in technology and concepts (which are accidental and rare). Rather, it could be based on bold evolution through the establishment of know-how, application of best practices, process effectiveness and high standards, performance measurement, and attention to

  1. The Law of Conservation of Energy in Chemical Reactions

    CERN Document Server

    Stepanov, I A

    2000-01-01

    Earlier it has been supposed that the law of conservation of energy in chemical reactions has the following form: DU=DQ-PDV+SUM(muiDN) In the present paper it has been proved by means of the theory of ordinary differential equations that in the biggest part of the chemical reactions it must have the following form: DU=DQ+PDV+SUM(muiDN) The result obtained allows to explain a paradox in chemical thermodynamics: the heat of chemical processes measured by calorimetry and by the Vant-Hoff equation differs very much from each other. The result is confirmed by many experiments.

  4. Residential energy-efficient technology adoption, energy conservation, knowledge, and attitudes: An analysis of European countries

    International Nuclear Information System (INIS)

    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.

  5. Energy conservation and management strategies in Heavy Water Plants

    International Nuclear Information System (INIS)

    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. 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.

  8. Credit tools to promote energy conservation: a possible federal role

    Energy Technology Data Exchange (ETDEWEB)

    1979-11-01

    An analysis is presented of the potential of banking institutions to assist in the promotion and implementation of energy conserving measures. Emphasis is given to urban problems and to a possible federal involvement with any measures taken. The relationship between commercial banks and their borrowers was examined. In order to assess a potential federal role, existing regulatory mechanisms were examined. Senior officers of commercial banks were interviewed. A review of relevant literature and federal regulations was undertaken. The fundamentals of lending decisions were reviewed and analyzed in order to develop an understanding of the function of energy considerations in the loan process. The large money-center bank, which satisfies the financial needs of the Fortune 500 borrowers and the city-wide or regional bank, which derives its business from local consumers, are considered.

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.

  10. Downstream-based Scheduling for Energy Conservation in Green EPONs

    KAUST Repository

    Chen, Shen

    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.

  11. Reducing fuel usage through applications of conservation and solar energy

    Solar thermal technology, coupled with aggressive conservation measures, offers the prospect of greatly reducing the dependence of industry on oil and natural gas. The near-term market for solar technology is largely in industrial processes operating at temperatures below 288/sup 0/C (550/sup 0/F). Such process heat can be supplied by the relatively unsophisticated solar equipment available today. The number and diversity of industrial plants using process heat at this temperature allows favorable matches between solar technologies and industrial processes. The problems involved with the installation and maintenance of conservation and solar equipment are similar. Both compete for scarce investment capital, and each complicates industrial operations and increases maintenance requirements. Technological innovations requiring new types of equipment and reducing the temperature requirements of industrial processes favor the introduction of solar hardware. The industrial case studies program at the Solar Energy Research Institute has examined technical, economic, and other problems facing the near-term application of solar thermal technology to provide industrial process heat. The plant engineer is in the front line of any measure to reduce energy consumption or to supplement existing fuel supplies. The conditions most favorable to the integration of solar technology are presented and illustrated with examples from actual industrial plants.

    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.

    1979-02-21

    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.

    Ester, P.

    1984-01-01

    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.)

  1. The valuation of environmental externalities in energy conservation planning

    International Nuclear Information System (INIS)

    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

  3. Gravitational Energy-Momentum and Conservation of Energy-Momentum in General Relativity

    Science.gov (United States)

    Wu, Zhao-Yan

    2016-06-01

    Based on a general variational principle, Einstein-Hilbert action and sound facts from geometry, it is shown that the long existing pseudotensor, non-localizability problem of gravitational energy-momentum is a result of mistaking different geometrical, physical objects as one and the same. It is also pointed out that in a curved spacetime, the sum vector of matter energy-momentum over a finite hyper-surface can not be defined. In curvilinear coordinate systems conservation of matter energy-momentum is not the continuity equations for its components. Conservation of matter energy-momentum is the vanishing of the covariant divergence of its density-flux tensor field. Introducing gravitational energy-momentum to save the law of conservation of energy-momentum is unnecessary and improper. After reasonably defining “change of a particle's energy-momentum”, we show that gravitational field does not exchange energy-momentum with particles. And it does not exchange energy-momentum with matter fields either. Therefore, the gravitational field does not carry energy-momentum, it is not a force field and gravity is not a natural force.

  4. Cool roofs as an energy conservation measure for federal buildings

    Energy Technology Data Exchange (ETDEWEB)

    Taha, Haider; Akbari, Hashem

    2003-04-07

    We have developed initial estimates of the potential benefits of cool roofs on federal buildings and facilities (building scale) as well as extrapolated the results to all national facilities under the administration of the Federal Energy Management Program (FEMP). In addition, a spreadsheet ''calculator'' is devised to help FEMP estimate potential energy and cost savings of cool roof projects. Based on calculations for an average insulation level of R-11 for roofs, it is estimated that nationwide annual savings in energy costs will amount to $16M and $32M for two scenarios of increased roof albedo (moderate and high increases), respectively. These savings, corresponding to about 3.8 percent and 7.5 percent of the base energy costs for FEMP facilities, include the increased heating energy use (penalties) in winter. To keep the cost of conserved energy (CCE) under $0.08 kWh-1 as a nationwide average, the calculations suggest that the incremental cost for cool roofs should not exceed $0.06 ft-2, assuming that cool roofs have the same life span as their non-cool counterparts. However, cool roofs usually have extended life spans, e.g., 15-30 years versus 10 years for conventional roofs, and if the costs of re-roofing are also factored in, the cutoff incremental cost to keep CCE under $0.08 kWh-1 can be much higher. In between these two ends, there is of course a range of various combinations and options.

  5. Energy conservation and chaos in the gravitationally driven Fermi oscillator

    1998-10-01

    Chaotic dynamics of the two-body conservative system, which consists of a particle of mass m bouncing elastically on a horizontal plate of mass M supported by an elastic spring, is investigated. The system integrates the properties of coupled oscillators with those of the bouncing-ball and impact oscillator problems. Results obtained by varying the mass ratio M/m and the spring constant k in numerical computations are presented in the form of time-dependent diagrams and discrete maps. The rich variety of resulting chaotic behavior includes strange attractors with fractal structure, resonant islands, crisis, and intermittency route to chaos. The system has a remarkable didactic value as an example of chaotic behavior in simple systems close to everyday experience. The integrable limit M=0 is appropriate for introducing the phase portraits and discussing the interrelationship between the shape of the potential energy curves and the resulting oscillatory motion.

  6. Topology control in MANET for efficient energy conservation

    Directory of Open Access Journals (Sweden)

    2013-06-01

    Full Text Available The MANET is a Mobile Ad-hoc Network. Topologycontrol is an important issue in design of MANETs,due to its nature of the node-mobility. Manysolutions are available for topology control in ad-hoc networks, centralized or distributed algorithmslike-i.e.GAF, LEACH, AFECA etc.The basic ideafor topology maintenance is to elect the leader andall the moving node information is collected by it.This basically referred as clustering in ad-hoccommunication. This paper proposes an energyconservation scheme for multi-hop ad-hoc wirelessnetwork, where it reduces energy consumptionduring idle-listening, without significantlydiminishing the capacity or connectivity of thenetwork. It is built on the observation that, when aregion of a sufficient density of nodes, only a smallnumber of them need to be ready at any time toforward traffic for active connections. It uses theclustering mechanism in a distributed manner. Themain issue in design of such scheme is to choose thenode status be-active or power save, in order toprovide energy efficient communication. In thispaper, we propose a schematic for the improvedforwarding backbone mechanism, which reactivelyutilizes information about ongoing communicationas well as the current power management mode ofnodes along potential routes. This proposed designreduces the energy consumption for the overallnetwork by almost 30%, and also with satiablenetwork performance. By the results and theiranalysis, it can be concluded, that this algorithmpreserves capacity and connectivity of network,decreases latency, and also provides significantenergy conservation

  7. A Moored Underwater Energy Conservation System for Profiling Measurement

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    There is a need to obtain the hydrologic data including ocean current, wave, temperature and so on in the South China Sea. A new profiling instrument which does not suffer from the damage due to nature forces or incidents caused by passing ships, is under development to acquire data from this area. This device is based on a taut single point mid-water mooring system. It incorporates a small, instrumented vertically profiling float attached via an electromechanical cable to a winch integral with the main subsurface flotation. On a pre-set schedule, the instrument float with sensors is winched up to the surface if there is no ship passing by, which is defined by an on-board miniature sonar. And it can be immediately winched down to a certain depth if the sonar sensor finds something is coming. Since, because of logistics, the area can only be visited once for a long time and a minimum of 10 times per day profiles are desired, energy demands are severe. To respond to these concerns, the system has been designed to conserve a substantial portion of the potential energy lost during the ascent phase of each profile and subsequently use this energy to pull the instrument down. Compared with the previous single-point layered measuring mode,it is advanced and economica1. At last the paper introduces the test in the South China Sea.

  8. Federal problems in energy law with special regard to the Hessian Energy Conservation Law

    International Nuclear Information System (INIS)

    The book deals with aspects of energy law which have arisen in the general political discussion of energy and particularly in the light of the Hessian Energy Conservation Law (HEnSPG). It shows that the concept of energy law is to be understood in a broad sense. The material can be attributed neither wholly to public nor to civil law and ranges from special regulations for cable-carried energy supplies to the ruling on renewable types of energy. However, it also contains the requirements for primary energy sources available as deposits and regulations on energy safety and conservation. Regulations on transport and disposal problems are also there and, not least, energy-related subsidy rules are to be ascribed to energy law. The at times stromy debate of recent years on ways forward in energy policy and in energy law is used as a starting-point for a weighing of the arguments, an indication of attempts at solutions and for showing a way forward for energy policies.

  9. Dilemma between economic development and energy conservation: Energy rebound effect in China

    International Nuclear Information System (INIS)

    Promoting technological development to improve energy efficiency has been the primary method of energy conservation in China. However, the existence of energy rebound effect will impose negative effects on the final result of energy saving. In this article, we adopt the Malmquist index approach to estimate the contribution of technological progress to economic growth. We also employ Logarithmic mean weight Divisia index (LMDI) to measure the impact of technological improvement on the energy intensity. Based on the above, we set up a model to estimate the technology-based energy rebound effect in China. The results show that, over 1981–2009, energy rebound effect amounts averagely to 53.2%, implying that China cannot simply rely on technical means to reduce energy consumption and emission. Economic instruments should also be applied as supplements to ensure results of energy conservation and emission reduction. -- Highlights: ► Two improvements in rebound effect calculation model are proposed. ► The size of energy rebound in Chinese macro-economic level is evaluated. ► Energy rebound effect over 1981–2009 in China is averagely up to 53.2%. ► Chinese policy for energy consumption reduction should focus on energy pricing reform.

    Maersta Nursing Home consists of an H-shaped ward building with 4x12 beds and a supply building. The design of the ward sections, with four blocks of equal size but incorporating different building methods and different installation services, has permitted comparative investigations of performance, energy savings, operating costs etc. The project has included everything from initial design and construction to performance measurement and assessment. Data from parameters affecting energy consumption has been continuously monitored over a period of more than three years. About ten million hourly mean values have been logged for the production and analysis of energy balances for individual components and for parts of the buildings. The report compares the performance of massive and light building structures with different insulation levels, different types of window design, airborne and waterborne heating systems regenerative and recuperative heat exchangers and other variables. Different types of water-saving taps are compared, as are economy-flush and normal-flush lavatories. The value of waste water heat exchangers, solar collectors for domestic hot water production, recovery of heat from refrigerator condensers, conversion of flushing desinfectors and so on are also considered. The objective has been achieved, and the results indicate that 50% savings can be obtained without any reduction in the standard of either thermal comfort or hygiene. In general, it can be said that well-planned energy conservation measures make it easier to establish a good indoor climate. The report also reveals that an energy-efficient building can be produced without incurring higher building costs. (authors).

  11. Effect of energy and momentum conservation on fluid resonances for resonant magnetic perturbations in a tokamak

    International Nuclear Information System (INIS)

    In this paper, the impact of momentum and energy conservation of the collision operator in the kinetic description for Resonant Magnetic Perturbations (RMPs) in a tokamak is studied. The particle conserving differential collision operator of Ornstein-Uhlenbeck type is supplemented with integral parts such that energy and momentum are conserved. The application to RMP penetration in a tokamak shows that energy conservation in the electron collision operator is important for the quantitative description of plasma shielding effects at the resonant surface. On the other hand, momentum conservation in the ion collision operator does not significantly change the results

    This article introduces a string of energy conservation measures adopted over the past several years by the RFCC unit at Shengli Petrochemical Complex, including the optimization of feedstock properties, the adoption of high-efficiency atomizing nozzles, the revamp of CO boiler, the atomization by means of dry gas, the post-burning of flue gas as well as the application of frequency converting machines and pumps, resulting in ideal effects. The energy consumption of the RFCC unit was gradually decreased to 2984.25 MJ/t from the original level of 3716.99 MJ/t. After comparing basic energy consumption values with actual consumption values, the authors have set forward measures for further energy conservation, such as the recovery of low-temperature excess heat contained in oil/gas streams exiting from the fractionation tower top, addition of the fourth cyclone, delivery of hot oil slurry, and heat tracing with hot water.

  3. K-12 Teacher Understanding of Energy Conservation: Conceptual Metaphor, Dissipation, and Degradation

    Science.gov (United States)

    Daane, Abigail R.

    In K-12 educational settings, conservation of energy is typically presented in two ways: the conservation of energy principle (energy is neither created nor destroyed) and the sociopolitical need to conserve energy (we guard against energy being used up). These two meanings of conservation typically remain disconnected from each other and can appear contradictory, even after instruction. In an effort to support teachers in building robust understandings of energy from their existing knowledge, I designed a study to investigate the productive ideas in K-12 teachers' conversations about energy. A micro-analysis of discourse, gestures, and artifacts of professional development courses revealed teachers' productive ideas about three aspects of energy: conceptual metaphor, dissipation and degradation. In learning about energy, K-12 teachers come to use conceptual metaphors in their own language and value attending to students' metaphorical language as a means of formative assessment. Teachers' conversations about dissipation suggest that apparent difficulties with energy conservation may have their roots in a strong association between forms of energy (thermal) and their perceptible indicators (warmth). Teachers address this challenge by employing an exaggeration strategy to locate the dissipated thermal energy, making the energy indicator perceptible. Finally, teachers' unprompted statements about sociopolitical aspects of energy are related to both statements from the NGSS and aspects of energy degradation. I conclude that energy conservation can be better taught and learned in K-12 Education by: 1) understanding and applying conceptual metaphors about energy in K-12 settings, 2) using prior experiences to better understand dissipative energy processes involving imperceptible thermal energy, thereby understanding how energy conservation applies in all situations, and 3) connecting productive ideas about sociopolitical aspects of energy to canonical physics.

  4. Energy conservation potential in China’s petroleum refining industry: Evidence and policy implications

    International Nuclear Information System (INIS)

    Highlights: • A long-term equilibrium relationship of energy demand in China’s petroleum refining industry is established. • The sectoral energy conservation potential is evaluated by using scenarios analysis. • Energy prices, enterprise scale, R and D investment and ownership structure affect electricity intensity. • Future policy for energy conservation in China’s petroleum refining industry is suggested. - Abstract: China is currently the second largest petroleum refining country in the world due to rapid growth in recent years. Because the petroleum refining industry is energy-intensive, the rapid growth in petroleum refining and development caused massive energy consumption. China’s urbanization process will guarantee sustained growth of the industry for a long time. Therefore, it is necessary to study the energy conservation potential of the petroleum industry. This paper estimates the energy conservation potential of the industry by applying a cointegration model to investigate the long-run equilibrium relationship between energy consumption and some factors such as energy price, enterprise scale, R and D investment and ownership structure. The results show that R and D investment has the greatest reduction impact on energy intensity, and the growth of market participants (i.e. the decline of the share of state-owned companies) can improve energy efficiency of this industry. Under the advanced energy-saving scenario, the accumulated energy conservation potential will reach 230.18 million tons of coal equivalent (tce). Finally, we provide some targeted policy recommendations for industrial energy conservation

  5. On the Coupling Effects between Elastic and Electromagnetic Fields from the Perspective of Conservation of Energy

    CERN Document Server

    Zhou, Peng

    2015-01-01

    In this paper, the law of conservation of energy is applied to analyze reversible and coupling processes between elastic and electromagnetic fields. This approach is here called the energy formulation. For simple physical processes such as mechanical movement, diffusion and electrodynamic process, it is shown their governing equations all satisfy the law of conservation of energy. Then, analysis is extended to coupling effects. First, it is found the constitutive equations of the linear direct and converse piezoelectric and piezomagnetic effects guarantee that energy is conserved during the conversion of energies. Second, analyses found that for the generalized Villari effects, the electromagnetic energy can be treated as an extra term in the generalized elastic energy. Third, both the laws of conservation of momentum and energy are used to analyze electrostriction and magnetostriction. It is argued that both of these strictive effects are induced by the Maxwell stress. In addition, their energy is purely ele...

  6. Energy conservation enthalpy control system and sensor therefor

    Energy Technology Data Exchange (ETDEWEB)

    Nickell, G.T.; Alexander, J.L. Sr.

    1978-01-17

    An energy conservation enthalpy control system utilizes a sensing unit for sensing the wet bulb temperature of sampled air, both outside air and return air, under conditions which approximate adiabatic saturation. The unit includes a housing adapted to pass filtered air through the unit. Water circulated throughout from a sump in the housing is intimately contacted and mixed with the air by a spray or an evaporative pad. A temperature sensing element located in the sump or in the airstream provides a signal indicating the wet bulb temperature of the air under adiabatic saturation conditions. The unit provides the inputs to a control system which operates to coordinate the operations of return air dampers, outside air dampers, and air conditioning equipment. When outside air reaches a wet bulb condition lower than the wet bulb condition of return air in the system, the control system operates to open or modulate the outside air dampers, close or modulate the return air dampers, and modulate or shutoff the chilled water in the system.

  7. Energy and conservation benefits from managed prairie biomass

    2011-01-01

    Marginally productive land, such as that enrolled in the Conservation Reserve Program (CRP), may provide acreage and economic incentives for cellulosic energy production. Improving the yields from these lands will help establish a biomass producer?s position in the marketplace. The effects of water and nitrogen on biomass yields were investigated in both a plot-scale experiment and a broad-scale survey of CRP lands. The plot-scale experiment demonstrated that irrigation improved mixed-species prairie biomass yields more than nitrogen fertilizer on coarse-textured, marginally productive soils. Experimental plots amended with both irrigation and moderate (but not high) nitrogen produced more biomass than other treatment combinations, but this trend was not statistically significant. The survey of biomass yields on CRP lands across four Midwestern States indicates that yields are better correlated with June rainfall than any other individual month. Applying nutrient-enriched water such as agricultural runoff could benefit prairie yields if applied at appropriate times.

  8. Problems in the implementation of energy conservation measures. II. Consumer motivation

    Energy Technology Data Exchange (ETDEWEB)

    Phillips, P.H.

    1977-10-15

    During the course of 1975 a national survey of household attitudes to energy use and conservation was undertaken. The study suggested that while the public are generally in favor of energy conservation, they do not practice it. The study highlighted the need to do more than merely raise the level of awareness of the need for energy conservation. The energy intensive nature of our life-style was identified as a critical constraint on the implementations of effective voluntary energy conservation programs. It was suggested that our pattern of energy use is so deeply embedded in our everyday behaviors that it would take more than the presentation of information to produce the necessary changes in behavior. Some of the problems involved in attempting to motivate the consumer to conserve energy using either an extrinsic or instrinsic motivational approach are explored. A general model of the energy system is employed to illustrate that changes in the informational environment must be accompanied by changes in the institutional environment if pro-conservation attitudes are to be converted into conserving behavior. The case of personal transportation is used to indicate the need for a comprehensive package of measures which not only motivate the consumer but also facilitate and reinforce positive behavior if the dual goals of satisfying personal mobility needs and energy conservation are to be satisfied.

  9. Energy management action plan: Developing a strategy for overcoming institutional barriers to municipal energy conservation

    Energy Technology Data Exchange (ETDEWEB)

    1992-12-31

    Energy offices working to improve efficiency of local government facilities face not only technical tasks, but institutional barriers, such as budget structures that do not reward efficiency, a low awareness of energy issues, and purchasing procedures based only on minimizing initial cost. The bureau, in working to remove such barriers in San Francisco, has identified 37 institutional barriers in areas such as operations & maintenance, purchasing, and facility design; these barriers were then reorganized into three groupings-- policy & attitudes, budget & incentives, and awareness & information-- and mapped. This map shows that the barriers mutually reinforce each other, and that a holistic approach is required for permanent change. The city`s recreation & parks department was used as a model department, and information about facility energy use was compiled into a departmental energy review. Staff interviews showed how barriers affect conservation. The bureau then generated ideas for projects to remove specific barriers and rated them according to potential impact and the resources required to implement them. Four of the six projects selected focused on maintenance staff: a cost- sharing lighting retrofit program, a boiler efficiency program, a departmental energy tracking system, and a budgetary incentive program for conservation. The other two projects are city-wide: promotion of a new term contract supplying energy-efficient light materials, and publication/distribution of ENERGY NEWS newsletter. A general methodology, the EMAP Strategy Guide, has been created to assist other energy offices in developing EMAPs.

  10. Energy management: a program of energy conservation for the community college facility. [Handbook

    Energy Technology Data Exchange (ETDEWEB)

    Various Authors

    1978-01-01

    This handbook developes helps for assessing and improving the energy efficiency of the community-college facility. The TEEM approach (Total Educational Energy Management) is a labor-intensive approach which requires the commitment and participation of all segments of the college community. The TEEM program presented here defines a series of tasks selected, ordered, and implemented in such a way as to achieve two basic objectives: (1) reducing campus energy requirements, and (2) meeting those reduced energy requirements more efficiently without adversely affecting the quality of educational programs. This guide to large-scale energy conservation on college campuses includes step-by-step procedures for establishing a program task force, defining specific tasks, and assigning responsibilities. Action plans are developed, energy consumption monitored, goals set, and conservation measures implemented. A series of appendices provides more detailed information, charts, and worksheets related to all aspects of energy use. The TEEM program provides the basic structure for achieving a significant reduction in campus energy costs.

  3. Energy Conservation in Waste Water Treatment Operation: a case study at Himmerfjaerden WWTP

    Energy Technology Data Exchange (ETDEWEB)

    Holmberg, M.; Andersson, R.

    2007-07-01

    Swedish wastewater treatment plants' energy usage equals a total of 0.6 TWh per year. Together with the Swedish drinking water treatment, the usage corresponds to approximately 1% of the total electrical energy consumption in Sweden. Potentials for a reduction of this usage do exist. However, very modest efforts for energy usage conservation are attempted. In a master thesis presented in 2006 by the authors of this article, the potential of energy conservation at Himmerfjaerden WWTP was investigated. The thesis establishes a general methodology for performing an energy conservation project at any wastewater treatment plant. The methodology is then applied to an actual wastewater treatment plant, Himmerfjaerden WWTP. Results when performing the energy conservation project and recommendations for future measures are presented. The thesis clearly shows the existence of a potential for reducing energy usage in wastewater treatment operation, not necessarily implying a negative impact on the quality of the process.

  4. Energy conservation behavioural intention: attitudes, subjective norm and self-efficacy

    Lee, J. W. C.; Tanusia, A.

    2016-08-01

    This paper examines the influence of attitude towards energy conservation at home, the attitude in the campus, subjective norm, and self-efficacy on energy conservation behavioural intention among students in a private university using the Theory of Planned Behaviour (TPB). Data was collected from about 194 students using a questionnaire developed from current literature on TPB. Data analysis using Smart PLS version 3.2.4 found that attitude towards energy conservation at home has an indirect significant influence on attitude towards energy conservation behavioural intention via the mediating effect of attitude towards energy conservation in the campus. Self-efficacy and subjective norm are also positively related to energy conservation intention. The study also indicates the suitability of the TPB in predicting behavioural intention through attitudes, subjective norms, and self-efficacy. Results suggest that energy education is vital in creating a positive attitude towards energy conservation while facilities managers in institutions need to formulate appropriate policies and regulations to inculcate the right attitude and behaviour towards energy saving.

  5. A New Energy Conservation Law for Time-Harmonic Electromagnetic Fields and Its Applications

    CERN Document Server

    Geyi, Wen

    2016-01-01

    We report a new energy conservation law for time-harmonic electromagnetic fields, which is valid for an arbitrary medium. In contrast to the well-established Poynting theorem for time-harmonic fields, the real part of the new energy conservation law gives an equation for the sum of stored electric and magnetic field energies and the imaginary part involves an equation related to the difference between the dissipated electric and magnetic energies. Universally applicable expressions for both the electric and magnetic field energies have been obtained and demonstrated to be valuable in characterizing the energy storage and transport properties in complex media. For a lossless isotropic and homogeneous medium, the new energy conservation law implies that the stored electromagnetic field energy of a radiating system enclosed by a surface is equal to the total field energy inside the surface subtracted by the energy flowing out of the surface.

    This volume contains technical material related to community energy conservation programs, and supplements the organizational material in Volume I. It is in looseleaf format so that sections related to specific topics can be easily copied or transferred to individuals responsible for various sorts of conservation, such as carpooling programs, building improvements, and community outreach. Three technical chapters are included, discussing topics in the areas of: internal city and county operations; community powers and regulations, and outreach programs. In the first, the concern is with what the community can do to reduce energy use in its own operations, an effective first step in promoting comprehensive energy conservation. The second chapter analyzes ways that the police power and fiscal powers of the community can be used for energy conservation, through building codes, zoning, and similar measures. In the final chapter, ways to promote energy conservation in the community are discussed: programs include outreach to households and firms, carpool promotion, waste oil recycling, etc.

  8. Illustrations of the Relativistic Conservation Law for the Center of Energy

    CERN Document Server

    Boyer, T H

    2005-01-01

    The relativistic conservation law involving the center of energy is reviewed and illustrated using simple examples from classical electromagnetic theory. It is emphasized that this conservation law is parallel to the conservation laws for energy, linear momentum, and energy, in arising from the generators of the Poincare group for electromagnetic theory; yet this relativistic law reflecting the continuous flow of energy goes virtually unmentioned in the text books. The illustrations here present situations both where external forces are present and are absent. The cases of a parallel plate capacitor, a flattened slip-joint solenoid, and two interacting charges are included.

  9. Assessment of the industrial energy-conservation program. Final report of the Committee on Assessment of the Industrial Energy Conservation Program

    Energy Technology Data Exchange (ETDEWEB)

    1982-01-01

    Industrial operations in the United States account for some 37% of the nation's consumptions of energy. It has been estimated that this figure will increase to 50% by 1990 unless appropriate industrial energy conservation measures are adopted. However, such measures are difficult to implement in spite of the potential of various existing, emerging, and advanced technologies that can be applied to the problem. Specifically, the application of many industrial energy conservation measures entails high economic, technological, and institutional risks and uncertainties that constrain industries from adopting such measures. Accordingly, in 1975 the federal government started a program designed to mitigate these risks and uncertainties via government-industry partnership arrangements in the interests of national energy conservation. An important element of this program is the Industrial Energy Conservation Program in the Federal Department of Energy (DOE). In June 1980, DOE asked the National Materials Advisory Board, a unit of the National Academy of Sciences-National Research Council, to form a study committee to assess the effectiveness of the Industrial Energy Conservation Program. The committee concluded that federal support embodied in the DOE program, present and planned, is important to conserving additional industrial energy. However, the committee also concluded that the program needs various improvements in project selection and management and in transfer of results to industry. The committee's findings and recommendations and the results of the deliberation of the committee's three panels, a special report on heat and power, and a report on the visit by four members of the committee to Japan are presented.

    The work in this project is based on a previous project (Energy Awareness Displays - Making the Invisible Visible) in which several measurement and visualization approaches have been developed to make employees more aware about energy consumption and pro-environmental behavior at the workplace. While awareness is a first important step for the decrease of energy consumption and environmental learning it is not sufficient as a means for sustainable behavior change. For this reason we have explored in the follow-up project approaches how pro-environmental behavior at the workplace can be encouraged, rewarded and sustained. For this purpose we have implemented several technological solutions and we have piloted these in form of an energy conservation game called Mindergie at the main campus of the Open University in Heerlen, Netherlands. The project is in line with an earlier identified research gap in terms of energy conservation at the workplace and uses state-of-the-art technologies for mobile gaming and rewarding of non-formal learning activities.

  11. Norway encourages energy conservation in Serbia; Norge fremmer ENOEK i Serbia

    Energy Technology Data Exchange (ETDEWEB)

    2003-07-01

    There is a great potential in Serbia for energy conservation and new technology after years of war. In practice, Serbia has lost 10 - 15 years and much must be rebuilt from the ground. Norway is working with Serbia to develop Serb know-how in the field of energy conservation. This involves consultative advice to the energy department in Belgrade for the development of a new energy act and the preparation of an energy report to the parliamentary assembly. There is also cooperation with the universities in order to establish four regional centres for energy conservation, and with several industrial companies to develop and implement definite investment projects. In Norway, several models for local energy conservation centres have been tried out during the last 20 years. These centres used to be financed by a mark-up on the electric tariff and they offered subsidized energy conservation counselling to the energy consumers. However, this did not work out well and the centres were removed from the electricity companies and now have to compete with other consultants to deliver the demanded services to the industries and private consumers. This false step will not be repeated in Serbia, where the energy conservation centres will be independent, commercial centres from the beginning. In developing this system, experience is drawn upon from Norwegian projects in many of the major cities in North-Western Russia.

    Field effect mobility in an organic device is determined by the activation energy. A new physical model of the activation energy is proposed by virtue of the energy and momentum conservation equations. The dependencies of the activation energy on the gate voltage and the drain voltage, which were observed in the experiments in the previous independent literature, can be well explained using the proposed model. Moreover, the expression in the proposed model, which has clear physical meanings in all parameters, can have the same mathematical form as the well-known Meyer-Neldel relation, which lacks of clear physical meanings in some of its parameters since it is a phenomenological model. Thus it not only describes a physical mechanism but also offers a possibility to design the next generation of high-performance optoelectronics and integrated flexible circuits by optimizing device physical parameter.

    2007-08-13

    We argue that a primary focus on energy efficiency may not be sufficient to slow (and ultimately reverse) the growth in total energy consumption and carbon emissions. Instead, policy makers need to return to an earlier emphasis on"conservation," with energy efficiency seen as a means rather than an end in itself. We briefly review the concept of"intensive" versus"extensive" variables (i.e., energy efficiency versus energy consumption), and why attention to both consumption and efficiency is essential for effective policy in a carbon- and oil-constrained world with increasingly brittle energy markets. To start, energy indicators and policy evaluation metrics need to reflect energy consumption as well as efficiency. We introduce the concept of"progressive efficiency," with the expected or required level of efficiency varying as a function of house size, appliance capacity, or more generally, the scale of energy services. We propose introducing progressive efficiency criteria first in consumer information programs (including appliance labeling categories) and then in voluntary rating and recognition programs such as ENERGY STAR. As acceptance grows, the concept could be extended to utility rebates, tax incentives, and ultimately to mandatory codes and standards. For these and other programs, incorporating criteria for consumption as well as efficiency offers a path for energy experts, policy-makers, and the public to begin building consensus on energy policies that recognize the limits of resources and global carrying-capacity. Ultimately, it is both necessary and, we believe, possible to manage energy consumption, not just efficiency in order to achieve a sustainable energy balance. Along the way, we may find it possible to shift expectations away from perpetual growth and toward satisfaction with sufficiency.

    Particle-in-cell (PIC) plasma simulations are a productive and valued tool for the study of nonlinear plasma phenomena, yet there are basic questions about the simulation methods themselves that remain unanswered. Here we study energy and momentum conservation by PIC. We employ both analysis and simulations of one-dimensional, electrostatic plasmas to understand why PIC simulations are either energy or momentum conserving but not both, what role a numerical stability plays in non-conservation, and how errors in conservation scale with the numerical parameters. Conserving both momentum and energy make it possible to model problems such as Jeans'-type equilibria. Avoiding numerical instability is useful, but so is being able to identify when its effect on the results may be important. Designing simulations to achieve the best possible accuracy with the least expenditure of effort requires results on the scaling of error with the numerical parameters. Our results identify the central role of Gauss' law in conservation of both momentum and energy, and the significant differences in numerical stability and error scaling between energy-conserving and momentum-conserving simulations.

  3. Energy potential of biomass from conservation grasslands in Minnesota, USA.

    Full Text Available Perennial biomass from grasslands managed for conservation of soil and biodiversity can be harvested for bioenergy. Until now, the quantity and quality of harvestable biomass from conservation grasslands in Minnesota, USA, was not known, and the factors that affect bioenergy potential from these systems have not been identified. We measured biomass yield, theoretical ethanol conversion efficiency, and plant tissue nitrogen (N as metrics of bioenergy potential from mixed-species conservation grasslands harvested with commercial-scale equipment. With three years of data, we used mixed-effects models to determine factors that influence bioenergy potential. Sixty conservation grassland plots, each about 8 ha in size, were distributed among three locations in Minnesota. Harvest treatments were applied annually in autumn as a completely randomized block design. Biomass yield ranged from 0.5 to 5.7 Mg ha(-1. May precipitation increased biomass yield while precipitation in all other growing season months showed no affect. Averaged across all locations and years, theoretical ethanol conversion efficiency was 450 l Mg(-1 and the concentration of plant N was 7.1 g kg(-1, both similar to dedicated herbaceous bioenergy crops such as switchgrass. Biomass yield did not decline in the second or third year of harvest. Across years, biomass yields fluctuated 23% around the average. Surprisingly, forb cover was a better predictor of biomass yield than warm-season grass with a positive correlation with biomass yield in the south and a negative correlation at other locations. Variation in land ethanol yield was almost exclusively due to variation in biomass yield rather than biomass quality; therefore, efforts to increase biomass yield might be more economical than altering biomass composition when managing conservation grasslands for ethanol production. Our measurements of bioenergy potential, and the factors that control it, can serve as parameters for assessing

    Forty-seven fuel conservation strategies are identified for commercial aviation and the fuel saving potential, costs, constraints, and current implementation levels of these options are examined. This assessment is based on a comprehensive review of published data and discussions with representatives from industry and government. Analyses were performed to quantify the fuel saving potential of each option, and to assess the fuel savings achieved to date by the airline industry. Those options requiring further government support for option implementation were identified, rated, and ranked in accordance with a rating methodology developed in the study. Finally, recommendations are made for future government efforts in the area of fuel conservation in commercial aviation.

    International Nuclear Information System (INIS)

    The Department of Energy (DOE) has prepared a Programmatic Environmental Assessment (PEA), DOE/EA 1068, to assess the environmental impacts associated with the State Energy Conservation Program (SECP). DOE previously funded SECP projects under the Energy Policy and Conservation Act of 1975 (EPCA). The State Energy Efficiency Programs Improvements Act of 1990 (SEEPIA) and the Energy Policy Act of 1992 (EPACT) amended EPCA to broaden the range of state initiatives qualifying for Federal assistance under the SECP. The PEA presents a general analysis of the potential environmental effects associated with broad types of projects that can be funded under the SECP. It does not analyze specific environmental effects or alternatives associated with individual energy conservation, energy efficiency, and renewable energy projects. Individual actions are to be evaluated in detail on a project-by-project basis to determine whether their impacts fall within the bounding analysis of the impacts analyzed in the SECP PEA

  10. Einstein's physical strategy, energy conservation, symmetries, and stability: "But Grossmann & I believed that the conservation laws were not satisfied"

    Science.gov (United States)

    Pitts, J. Brian

    2016-05-01

    Recent work on the history of General Relativity by Renn et al. shows that Einstein found his field equations partly by a physical strategy including the Newtonian limit, the electromagnetic analogy, and energy conservation. Such themes are similar to those later used by particle physicists. How do Einstein's physical strategy and the particle physics derivations compare? What energy-momentum complex(es) did he use and why? Did Einstein tie conservation to symmetries, and if so, to which? How did his work relate to emerging knowledge (1911-1914) of the canonical energy-momentum tensor and its translation-induced conservation? After initially using energy-momentum tensors hand-crafted from the gravitational field equations, Einstein used an identity from his assumed linear coordinate covariance xμ‧ = Mνμ xν to relate it to the canonical tensor. Usually he avoided using matter Euler-Lagrange equations and so was not well positioned to use or reinvent the Herglotz-Mie-Born understanding that the canonical tensor was conserved due to translation symmetries, a result with roots in Lagrange, Hamilton and Jacobi. Whereas Mie and Born were concerned about the canonical tensor's asymmetry, Einstein did not need to worry because his Entwurf Lagrangian is modeled not so much on Maxwell's theory (which avoids negative-energies but gets an asymmetric canonical tensor as a result) as on a scalar theory (the Newtonian limit). Einstein's theory thus has a symmetric canonical energy-momentum tensor. But as a result, it also has 3 negative-energy field degrees of freedom (later called "ghosts" in particle physics). Thus the Entwurf theory fails a 1920s-1930s a priori particle physics stability test with antecedents in Lagrange's and Dirichlet's stability work; one might anticipate possible gravitational instability. This critique of the Entwurf theory can be compared with Einstein's 1915 critique of his Entwurf theory for not admitting rotating coordinates and not getting

  15. Regional Differences in China's Energy Efficiency and Conservation Potentials

    2007-01-01

    This paper investigates the maximum energy efficiency level and the energy saving potentials in each region in China that can be practically attained at current economic and technological development levels. Most of the nation's energy efficient provinces are found along the coast of southeast China, while most of its least energy efficient provinces are in the hinterland that is rich in coal resources, and which depends heavily on coal consumption. China's low efficiency in energy resource allocation stems from its secondary industry, which is handicapped by the lowest energy efficiency and the most striking regional differentials. 4comparison of the factors affecting the energy efficiency shows that the provinces being compared in this study differ tremendously in energy consumption structure, technological level of the secondary industry, and abundance of energy resources, and that the other factors are only adequate, rather than necessary, conditions. It is imperative to rectify the behaviors of provinces in balancing local energy allocation, to channel energy resources to energy efficient provinces, and to improve the national energy efficiency as a whole. When taking energy-saving steps, provinces must take into full consideration both the national and local factors that affect energy efficiency. Furthermore, it is unrealistic for China to set a unified energy saving goal for different provinces.

    The New York Industrial Retention Network (NYIRN) manages the RenewableNY program to assist industrial companies in New York City to implement energy efficiency projects. RenewableNY provides companies with project management assistance and grants to identify opportunities for energy savings and implement energy efficiency projects. The program helps companies identify energy efficient projects, complete an energy audit, and connect with energy contractors who install renewable energy and energy efficient equipment. It also provides grants to help cover the costs of installation for new systems and equipment. RenewableNY demonstrates that a small grant program that also provides project management assistance can incentivize companies to implement energy efficiency projects that might otherwise be avoided. Estimated savings through RenewableNY include 324,500 kWh saved through efficiency installations, 158 kW of solar energy systems installed, and 945 thm of gas avoided.

  18. Energy, Metaphysics, and Space: Ernst Mach's Interpretation of Energy Conservation as the Principle of Causality

    Science.gov (United States)

    Guzzardi, Luca

    2014-06-01

    This paper discusses Ernst Mach's interpretation of the principle of energy conservation (EC) in the context of the development of energy concepts and ideas about causality in nineteenth-century physics and theory of science. In doing this, it focuses on the close relationship between causality, energy conservation and space in Mach's antireductionist view of science. Mach expounds his thesis about EC in his first historical-epistemological essay, Die Geschichte und die Wurzel des Satzes von der Erhaltung der Arbeit (1872): far from being a new principle, it is used from the early beginnings of mechanics independently from other principles; in fact, EC is a pre-mechanical principle which is generally applied in investigating nature: it is, indeed, nothing but a form of the principle of causality. The paper focuses on the scientific-historical premises and philosophical underpinnings of Mach's thesis, beginning with the classic debate on the validity and limits of the notion of cause by Hume, Kant, and Helmholtz. Such reference also implies a discussion of the relationship between causality on the one hand and space and time on the other. This connection plays a major role for Mach, and in the final paragraphs its importance is argued in order to understand his antireductionist perspective, i.e. the rejection of any attempt to give an ultimate explanation of the world via reduction of nature to one fundamental set of phenomena.

  20. An approach to enhance the conservation-compatibility of solar energy development.

    D Richard Cameron

    Full Text Available The rapid pace of climate change poses a major threat to biodiversity. Utility-scale renewable energy development (>1 MW capacity is a key strategy to reduce greenhouse gas emissions, but development of those facilities also can have adverse effects on biodiversity. Here, we examine the synergy between renewable energy generation goals and those for biodiversity conservation in the 13 M ha Mojave Desert of the southwestern USA. We integrated spatial data on biodiversity conservation value, solar energy potential, and land surface slope angle (a key determinant of development feasibility and found there to be sufficient area to meet renewable energy goals without developing on lands of relatively high conservation value. Indeed, we found nearly 200,000 ha of lower conservation value land below the most restrictive slope angle (<1%; that area could meet the state of California's current 33% renewable energy goal 1.8 times over. We found over 740,000 ha below the highest slope angle (<5%--an area that can meet California's renewable energy goal seven times over. Our analysis also suggests that the supply of high quality habitat on private land may be insufficient to mitigate impacts from future solar projects, so enhancing public land management may need to be considered among the options to offset such impacts. Using the approach presented here, planners could reduce development impacts on areas of higher conservation value, and so reduce trade-offs between converting to a green energy economy and conserving biodiversity.

    1980-03-01

    The State Energy Conservation Program was established in 1975 to promote energy conservation and to help states develop and implement their own conservation programs. Base (5) and supplemental (3) programs required states to implement programs including: mandatory thermal-efficiency standards and insulation requirements for new and renovated buildings; mandatory lighting efficiency standards for public buildings; mandatory standards and policies affecting the procurement practices of the state and its political subdivisions; program measures to promote the availability and use of carpools, vanpools, and public transportation; a traffic law or regulation which permits a right turn-on-red; and procedures to carry out a continuing public education effort to increase awareness of energy conservation; procedures which promote effective coordination among local, state, and Federal energy conservation programs; and procedures for carrying out energy audits on buildings and industrial plants. All 50 states and Puerto Rico, Guam, the Virgin Islands, American Samoa, and the District of Columbia participated in the program. The total 1980 energy savings projected by the states is about 5.9 quadrillion Btu's or about 7% of the DOE projected 1980 baseline consumption of just under 83 quads. The detailed summary is presented on the following: information the SECP evaluation; DOE response to the SECP; DOE's role in the program management process; the effectiveness of the states in managing the SECP; the status of program measure implementation; innovative state energy conservation programs; and the evaluation methodology.

  2. Estimating energy conservation potential in China's commercial sector

    International Nuclear Information System (INIS)

    With low energy intensity and great potential for growth, the commercial sector has become one of the key sectors for energy conservation and emission reduction in the context of China's rapid urbanization process. Based on the EIA (Energy Information Administration) statistical methods, this paper calculates the energy consumption of China's commercial sector from 1981 to 2012, specifies the determinants of commercial energy demand, forecasts future energy consumption and estimates the energy conservation potentials using the Johansen co-integration methodology. The results indicate: (i) GDP (Gross Domestic Product) and urbanization have positive effects on the energy consumption of the commercial sector while labor productivity and energy price contribute to reduction in the sector's energy consumption. (ii) Under the basic scenario, energy consumption of the commercial sector will be 317.34 and 469.84 Mtce (million tons of coal equivalent) in 2015 and 2020 respectively. (iii) Under the moderate and advanced scenario, about 187.00 and 531.45 Mtce respectively of the energy consumption of the commercial sector can be conserved from 2013 to 2020. The findings have important implications for policy-makers to enact energy-saving policies. - Highlights: • Calculation of China's commercial energy consumption and saving potential. • Co-integration model is applied to estimate commercial energy efficiency. • Decomposition of driving forces of energy consumption. • Future policies for commercial energy efficiency are discussed

    Pacific Northwest Laboratory (PNL) has analyzed the changes in consumer energy conservation attitudes and behaviors in the Pacific Northwest between 1983 and 1985. The information was collected through stratified random telephone surveys on 2000 and 1058 households, respectively, for 1983 and 1985 in the Bonneville Power Administration (BPA) service area in Idaho, Oregon, Washington and Western Montana. This report covers four topic areas and tests two hypotheses. The topics are as follows: consumer perceptions and attitudes of energy use and conservation in the home; consumer perceptions of energy institutions and other entities; past and intended conservation actions and investments; and segmentation of homeowners into market prospect groups. The hypotheses tested are as follows: (1) There has been no change in the size and psychographic make-up of the original three market segments found in the 1983 survey analysis; and (2) image profiles of institutions with respect to familiarity, overall impression, and believability as sources of energy conservation information remain unchanged since 1983.

    The report assesses the availability and implementation of energy conservation technology, particularly in the residential sector. Of concern is that energy-conserving innovations are restricted and, in some cases, blocked entirely from reaching the marketplace by a variety of institutional barriers. An ERDA-sponsored project to identify practical policy or program options whose implementation would increase the rate and degree of market penetration of these products is summarized. From research performed over a five-month period, the report describes the results of a survey of energy-conserving products and certification practices and procedures; energy-conserving products identified as being restricted; identification and analysis of the effects of these barriers; and the recommendations of policies and programs to mitigate the effects of the identified barriers.

  7. Energy conservation and emission reduction policies for the electric power industry in China

    International Nuclear Information System (INIS)

    Because of China's increasingly limited energy supplies and serious environmental pollution, much attention has been paid to conserving energy and reducing emissions to help the country's economy achieve sustainable development. As the electric power industry is the largest consumer of coal resources in China and also emits high levels of air pollutants each year, the Chinese government has enacted many technical and economic policies for energy conservation and emission reduction in the last few years. These policies are summarized in this paper, along with relevant laws and medium- and long-term plans, all of which address ideas such as adjusting the power generation mix, promoting demand-side management, introducing energy-efficient scheduling, and installing desulfurization units. The paper also assesses the results of these policies by analyzing several key indicators of energy consumption and emissions. The analysis shows that although some progress has been made in conserving energy and reducing emissions, substantial work is still required for China to catch up with developed countries. Some suggestions for future work are provided. - Highlights: → China has made many policies for reducing the power industries' energy consumption and emissions. → Progress has been made in conserving energy and reducing emission of the electric power industry. → Substantial works need to be done for China to catch up with the level of developed country. → Market mechanisms for conserving energy and reducing emission should be constructed in the future.

    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.

    In a natural system, coupling effects among different physical fields substantially reflect the conversion of energy from one form to another. According to the law of conservation of energy (LCE), the loss of energy in one field must equal to the gain of energy in another field. In this paper, this LCE is applied to analyze the reversible processes coupled between elastic and electromagnetic fields. Here, it is called the energy formulation. For simple physical processes such as mechanical mo...

    Full Text Available Mobile Ad-hoc network (MANET is infrastructure less network in which nodes are mobile, self reconfigurable, battery powered. As nodes in MANET are battery powered, energy saving is an important issue. We are using routing protocol to save energy so as to extend network lifetime. We have extended original Optimized Linked State Routing (OLSR protocol by using two algorithms and named it as Enhancement in OLSR using Residual Energy approach (EOLSRRE and Enhancement in OLSR using Energy Consumption approach (EOLSR-EC. To analyze relative performance of modified protocol EOLSR-RE and EOLSR-EC over OLSR, we performed various trials using Qualnet simulator. The performance of these routing protocols is analyzed in terms of energy consumption, control overheads, end to end delay, packet delivery ratio. The modified OLSR protocol improves energy efficiency of network by reducing 20 % energy consumption and 50% control overheads.

    2016-03-01

    We describe the development of a density-dependent transferable coarse-grain model of crystalline hexahydro-1,3,5-trinitro-s-triazine (RDX) that can be used with the energy conserving dissipative particle dynamics method. The model is an extension of a recently reported one-site model of RDX that was developed by using a force-matching method. The density-dependent forces in that original model are provided through an interpolation scheme that poorly conserves energy. The development of the new model presented in this work first involved a multi-objective procedure to improve the structural and thermodynamic properties of the previous model, followed by the inclusion of the density dependency via a conservative form of the force field that conserves energy. The new model accurately predicts the density, structure, pressure-volume isotherm, bulk modulus, and elastic constants of the RDX crystal at ambient pressure and exhibits transferability to a liquid phase at melt conditions.

    More efficient use of energy resources can be promoted by various regulatory means, i.e., taxation, subsidies, and pricing. Various incentives can be provided by income and revenue tax breaks-deductible energy audit fees, energy saving investment credits, breaks for energy saving entrepreneurs, and energy savings accounts run through utility accounts. Value added and excise taxes can also be adjusted to reward energy saving investments and energy saving entrepreneurial activity. Incentives can be provided in the form of cash refunds, including trade-in-and-scrap programs and reimbursements or subsidies on audit costs and liability insurance. Pricing incentives include lower rates for less energy use, prepayment of deposit related to peak load use, electronically dispatched multiple tariffs, savings credits based on prior peak use, and subsidized {open_quotes}leasing{close_quotes} of more efficient appliances and lights. Credits, with an emphasis on pooling small loans, and 5-year energy savings contracts are also discussed.

  11. Residential energy use and conservation in Venezuela: Results and implications of a household survey in Caracas

    Energy Technology Data Exchange (ETDEWEB)

    Figueroa, M.J.; Ketoff, A.; Masera, O.

    1992-10-01

    This document presents the final report of a study of residential energy use in Caracas, the capital of Venezuela. It contains the findings of a household energy-use survey held in Caracas in 1988 and examines options for introducing energy conservation measures in the Venezuelan residential sector. Oil exports form the backbone of the Venezuelan economy. Improving energy efficiency in Venezuela will help free domestic oil resources that can be sold to the rest of the world. Energy conservation will also contribute to a faster recovery of the economy by reducing the need for major investments in new energy facilities, allowing the Venezuelan government to direct its financial investments towards other areas of development. Local environmental benefits will constitute an important additional by-product of implementing energy-efficiency policies in Venezuela. Caracas`s residential sector shows great potential for energy conservation. The sector is characterized by high saturation levels of major appliances, inefficiency of appliances available in the market, and by careless patterns of energy use. Household energy use per capita average 6.5 GJ/per year which is higher than most cities in developing countries; most of this energy is used for cooking. Electricity accounts for 41% of all energy use, while LPG and natural gas constitute the remainder. Specific options for inducing energy conservation and energy efficiency in Caracas`s residential sector include energy-pricing policies, fuel switching, particularly from electricity to gas, improving the energy performance of new appliances and customer information. To ensure the accomplishment of an energy-efficiency strategy, a concerted effort by energy users, manufacturers, utility companies, government agencies, and research institutions will be needed.

  12. An approach to enhance the conservation-compatibility of solar energy development.

    2012-01-01

    The rapid pace of climate change poses a major threat to biodiversity. Utility-scale renewable energy development (>1 MW capacity) is a key strategy to reduce greenhouse gas emissions, but development of those facilities also can have adverse effects on biodiversity. Here, we examine the synergy between renewable energy generation goals and those for biodiversity conservation in the 13 M ha Mojave Desert of the southwestern USA. We integrated spatial data on biodiversity conservation value, solar energy potential, and land surface slope angle (a key determinant of development feasibility) and found there to be sufficient area to meet renewable energy goals without developing on lands of relatively high conservation value. Indeed, we found nearly 200,000 ha of lower conservation value land below the most restrictive slope angle (offset such impacts. Using the approach presented here, planners could reduce development impacts on areas of higher conservation value, and so reduce trade-offs between converting to a green energy economy and conserving biodiversity.

  13. Policy instruments for energy conservation: A multidimensional assessment

    International Nuclear Information System (INIS)

    This thesis evaluates the effectiveness of various forms of taxes, subsidies and regulations implemented to correct for market failures that may prevent energy savings. It builds on various approaches, with gradual complexity. First, a standard micro-economic model is developed to compare the static performances of these instruments. Second, the representation of consumer behaviour is strengthened in a model of the residential energy demand for space heating in France, which allows to identify the dynamic mechanisms by which instruments can correct for the main market failures. Third, an empirical evaluation of 'white certificate' schemes - tradable energy saving obligations imposed on energy operators - is made from the comparison between the British, Italian and French experiences, taking into account national institutions. The following conclusions can be drawn from these various approaches: (i) energy taxes, by encouraging both energy efficiency investment and sufficiency behaviour, are particularly effective; (ii) energy efficiency regulations have a significant impact on the diffusion of efficient technologies; (iii) subsidies to energy efficiency induce a large rebound effect; (iv) depending on the institutional environment in which they operate, white certificate schemes combine different properties of these instruments. Applied to the French residential building sector, the most effective combination of these instruments does not allow to reach the energy saving target set by the Government. (author)

    The Augustine Band of Cahuilla Indians was awarded a grant through the Department of Energy First Steps program in June of 2006. The primary purpose of the grant was to enable the Tribe to develop energy conservation policies and a strategy for alternative energy resource development. All of the work contemplated by the grant agreement has been completed and the Tribe has begun implementing the resource development strategy through the construction of a 1.0 MW grid-connected photovoltaic system designed to offset a portion of the energy demand generated by current and projected land uses on the Tribe’s Reservation. Implementation of proposed energy conservation policies will proceed more deliberately as the Tribe acquires economic development experience sufficient to evaluate more systematically the interrelationships between conservation and its economic development goals.

    This study examines the causal relationships among energy consumption, economic growth and carbon dioxide emissions in twenty countries from Latin America and the Caribbean region. The methodology includes the use of Phillips and Perron (PP) tests, a cointegration model with vector error correction modeling (VECM) and vector autoregression (VAR) with Granger causality. The study concludes that of the twenty countries analyzed, only in four of them will it be possible to implement energy conservation polices without affecting their economic growth, four others are not able to consider an energy conservation policy with economic growth, and the other twelve should focus on their economic growth before adopting any conservation policies. Energy efficiency was found in this region, especially in the countries which have both cointegration and short-term equilibrium. - Highlights: > Only four countries could implement energy conservation polices without affecting economic growth. > Twelve nations should focus on their economic growth before designing any energy conservation policies. > Energy efficiency was found in the countries which have both cointegration and short-term equilibrium.

  16. Lessons for integrated household energy conservation policies from an intervention study in Singapore

    International Nuclear Information System (INIS)

    In preparation for a community energy conservation program in the southwest district of Singapore, a pilot intervention study was conducted between August and November 2008 to study the effectiveness of tailored information and feedback in promoting household conservation. A sample of 125 households was involved in the study, of which 63 were the control group. Both self-reported behavioral changes and actual energy reductions were measured and any Hawthorne effect was identified. It was found that self-reported behavioral changes were strongly correlated to the level of trust in the energy conservation information given, the need for ease in practicing the recommended conservation measures and feeling of satisfaction in executing the measures; these results differ from several past studies on energy interventions. 60.7% of those who reported behavioral changes actually reduced energy consumption. Reasons were found and discussed. Lessons from this intervention study can be applied to design integrated policies aimed at promoting energy conservation in households. - Highlights: ► Energy intervention was implemented on 125 households. ► Outreach instruments included stickers, pamphlets and counseling. ► Self-reported behavioral and actual reductions were recorded. ► Self-reported behavioral change was only correlated to trust of information given. ► It was also correlated to ease of actions and feeling of satisfaction from actions.

    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.

    2013-01-01

    The U.S. Department of Energy (DOE) awarded the Center for Transportation and the Environment (CTE) federal assistance for the management of a project to develop and test a prototype flywheel-based energy recovery and storage system in partnership with Test Devices, Inc. (TDI). TDI specializes in the testing of jet engine and power generation turbines, which uses a great deal of electrical power for long periods of time. In fact, in 2007, the company consumed 3,498,500 kW-­hr of electricity in their operations, which is equivalent to the electricity of 328 households. For this project, CTE and TDI developed and tested a prototype flywheel-based energy recovery and storage system. This technology is being developed at TDI’s facilities to capture and reuse the energy necessary for the company’s core process. The new technology and equipment is expected to save approximately 80% of the energy used in the TDI process, reducing total annual consumption of power by approximately 60%, saving approximately two million kilowatt-hours annually. Additionally, the energy recycling system will allow TDI and other end users to lower their peak power demand and reduce associated utility demand charges. The use of flywheels in this application is novel and requires significant development work from TDI. Flywheels combine low maintenance costs with very high cycle life with little to no degradation over time, resulting in lifetimes measured in decades. All of these features make flywheels a very attractive option compared to other forms of energy storage, including batteries. Development and deployment of this energy recycling technology will reduce energy consumption during jet engine and stationary turbine development. By reengineering the current inefficient testing process, TDI will reduce risk and time to market of efficiency upgrades of gas turbines across the entire spectrum of applications. Once in place the results from this program will also help other US industries

  2. Conservation of Energy for Crowd Self-Driven Motion

    CERN Document Server

    Wang, Peng; Marsh, Kerry L

    2013-01-01

    For centuries, how an object moves given external forces is characterized by physical laws. As for creatures like human, their movements are self-driven, and the driving forces are generated by intention of people in a psychological sense. How to capture this characteristic in consistency with known physics laws is meaningful to understand human behaviors. By investigating a Newtonian-like model of a pedestrian, this paper presents a fluid-like model of crowd, showing that the physical concept of energy is also suited for psychological study of human collective behaviors. An energy balance equation is derived to characterize how the energy is transformed between the psychological forms and physical forms: the psychological drive arises as a potential form of energy, which aims at either accelerating or compressing a crowd as transformed to energy in physical forms (e.g., kinetic energy or static energy). If such transformation cannot be realized, disorder of the crowd may appear as a possible result. Based on...

  3. The potential for energy conservation in the United States

    Energy Technology Data Exchange (ETDEWEB)

    Carlsmith, R.S. [Oak Ridge National Laboratory, TN (United States)

    1993-12-31

    The period of high oil prices between 1973 and 1985 was traumatic in the United States, as it was also in the rest of the world. It was also instructive in showing the kinds of adaptation that could occur rapidly in a very large industrialized economy. During the period, energy use remained essentially constant while the economy continued to grow. The efficiency of energy use, as indicated by the ratio of energy consumption to gross domestic product, increased by 24 percent. Since 1985 there has been little further improvement in energy efficiency. Can this kind of improvement in efficiency be repeated, and if so, what can make it happen? A number of energy analysts have recently made projections for the next 20 years. The projections all indicate steady increases of about 1 percent per year in the level of energy use. Since these projections assumed that gross domestic product will increase by about 2.3 percent per year, the implication is that energy efficiency is expected to increase slowly during the next two decades.

  6. Interregional sharing of energy conservation targets in China: Efficiency and equity

    Science.gov (United States)

    Wei, Dan

    Energy conservation is a long-term strategic policy in China to support its economic and social development. This policy strategy is important for saving resources, protecting the environment, and ensuring the secure supply of energy to all economic activities. However, energy conservation often involves large amounts of investment and may also have dampening impacts on some local and regional economies. Moreover, energy conservation and efficiency improvement have many features of a public good. Therefore, government policy and intervention play a strong role to foster regional efforts and cooperative interregional actions on this issue. This dissertation introduces and analyzes a promising policy instrument---an interregional energy conservation-quota trading system---to help China fulfill its national energy conservation objective in an efficient and equitable way. To analyze the workings of the energy conservation-quota trading system, trading entities are first determined. In this study, statistical analyses (principal component analysis and cluster analysis) are applied to identify regional aggregations of provinces of China to act as the trading units. The marginal energy conservation cost curves of these regions are developed using engineering-economic methods and regression analysis. Simulations of interregional conservation-quota trading are undertaken after China's conservation goals in 2010 are allocated among regions according to several equity criteria. Various equity criteria are applied and analyzed in this study because of the philosophical differences in the appropriate definition of the concept. The trading simulations yield several important findings. First, the introduction of an interregional quota trading system can minimize both regional net compliance costs and national total conservation costs, irrespective of how the conservation tasks are initially allocated among regions according to different equity rules. Second, regional welfare

    Carnegie Mellon University was teamed with the Alcoa Technical Center with support from the US Dept. of Energy (Office of Industrial Technology) and the Pennsylvania Technology Investment Authority (PTIA) to make processing of aluminum less costly and more energy efficient. Researchers in the Department of Materials Science and Engineering have investigated how annealing processes in the early stages of aluminum processing affect the structure and properties of the material. Annealing at high temperatures consumes significant amounts of time and energy. By making detailed measurements of the crystallography and morphology of internal structural changes they have generated new information that will provide a scientific basis for shortening processing times and consuming less energy during annealing.

    Full Text Available Russian agricultural production at current stage is very energy intensive. At the cost of agricultural production overall cost of energy resources is growing: in 2000 was 36.5 billion rubles, 2008 - 92 billion rubles, 2009 - 110.6 billion rubles, and in 2010 rose to 119.8 billion rubles, or increased by 3.3 times. The analysis of consumption of the main energy sources for the period from 1990 to 2010 showed a decrease in general and the specific consumption of diesel fuel, gasoline and electricity by 5-7 times. Reducing energy consumption is explained as a forced saving resources because of lack of funds for the acquisition and implementation of agricultural enterprises of energy and resource saving measures (resource-saving technologies in the production process, motor fuel, biofuels and alternative energy sources. To solve this problem State and business in a matter of priority should be to build an effective system of innovation development for agriculture, promote the participation of agricultural science and education system in this process, modernize the domestic agricultural machinery, engineering and technology infrastructure.

  12. Building Energy Efficiency in India: Compliance Evaluation of Energy Conservation Building Code

    2014-03-26

    India is experiencing unprecedented construction boom. The country doubled its floorspace between 2001 and 2005 and is expected to add 35 billion m2 of new buildings by 2050. Buildings account for 35% of total final energy consumption in India today, and building energy use is growing at 8% annually. Studies have shown that carbon policies will have little effect on reducing building energy demand. Chaturvedi et al. predicted that, if there is no specific sectoral policies to curb building energy use, final energy demand of the Indian building sector will grow over five times by the end of this century, driven by rapid income and population growth. The growing energy demand in buildings is accompanied by a transition from traditional biomass to commercial fuels, particularly an increase in electricity use. This also leads to a rapid increase in carbon emissions and aggravates power shortage in India. Growth in building energy use poses challenges to the Indian government. To curb energy consumption in buildings, the Indian government issued the Energy Conservation Building Code (ECBC) in 2007, which applies to commercial buildings with a connected load of 100 kW or 120kVA. It is predicted that the implementation of ECBC can help save 25-40% of energy, compared to reference buildings without energy-efficiency measures. However, the impact of ECBC depends on the effectiveness of its enforcement and compliance. Currently, the majority of buildings in India are not ECBC-compliant. The United Nations Development Programme projected that code compliance in India would reach 35% by 2015 and 64% by 2017. Whether the projected targets can be achieved depends on how the code enforcement system is designed and implemented. Although the development of ECBC lies in the hands of the national government – the Bureau of Energy Efficiency under the Ministry of Power, the adoption and implementation of ECBC largely relies on state and local governments. Six years after ECBC

    International Nuclear Information System (INIS)

    The use of renewable energy has experienced in Fukushima Prefecture in the years after the reactor accident in March 2011, a substantial upswing. In total 500 MW of renewable energy capacity have been installed. According to the plans of the prefecture this capacity should be increased in 2020 to a total of just over 8 gigawatts. As in the rest of the country parts also, the solar energy was primarily used; this accounted 295 MW alone. In future, the priorities but more are in the areas of wind energy and hydropower.

  3. Final Report: Weatherization and Energy Conservation Education and Home Energy and Safety Review in the Aleutian Islands

    2011-08-30

    Aleutian/Pribilof Islands Association, Inc. (APIA) hired three part-time local community members that desire to be Energy Technicians. The energy technicians were trained in methods of weatherization assistance, energy conservation and home safety. They developed a listing of homes in the region that required weatherization, and conducted on-site weatherization and energy conservation education and a home energy and safety reviews in the communities of Akutan, False Pass, King Cove and Nelson Lagoon. Priority was given to these smaller communities as they tend to have the residences most in need of weatherization and energy conservation measures. Local residents were trained to provide all three aspects of the project: weatherization, energy conservation education and a home energy and safety review. If the total energy saved by installing these products is a 25% reduction (electrical and heating, both of which are usually produced by combustion of diesel fuel), and the average Alaska home produces 32,000 pounds of CO2 each year, so we have saved about: 66 homes x 16 tons of CO2 each year x .25 = 264 tons of CO2 each year.

  5. An Energy Conservative Wireless Sensor Networks Approach for Precision Agriculture

    Directory of Open Access Journals (Sweden)

    Jing Li

    2013-12-01

    Full Text Available Reducing energy consumption of sensor nodes to prolong the lifetime of finite-capacity batteries and how to enhance the fault-tolerant ability of networks are the major challenges in design of Wireless Sensor Networks (WSNs. In this paper, we present an energy-efficient system of WSNs for black pepper monitoring in tropical areas. At first, we optimized the base station antenna height in order to facilitate reliable communication, after which the Energy-efficient Sensor Protocol for Information via Negotiation (ESPIN routing protocol was utilized to solve the energy saving challenge. We conducted radio propagation experiments in actual black pepper fields. The practical test results illustrate that the ESPIN protocol reduces redundant data transmission and whole energy consumption of network, and enhances the success rate of data transmission compared with traditional Sensor Protocol for Information via Negotiation (SPIN protocol. To further optimize topology for improving the network lifetime, we designed a symmetrical double-chain (SDC topology which is suitable to be deployed in farmland and compared the lifetime with traditional tree topology. Experiment results indicate SDC topology has a longer network lifetime than traditional tree topology. The system we designed will greatly help farmers to make more informed decisions on the efficient use of resources and hence improve black pepper productivity.

  6. Conservation vs. renewable energy: Cases studies from Hawaii

    International Nuclear Information System (INIS)

    State of Hawaii generates about 90 percent of its electricity from imported fossil fuel sources. Thus, there is pressure from both public and policy makers to reduce the State dependency on foreign fossil fuel sources. To this extend, there are incentives created at State and Federal level for both residential and commercial buildings to install photovoltaic (PV) systems. Although such incentives are necessary for long-term objectives, it is shown in this study that retrofitting inefficient old building-equipment is another viable source to reduce the State of Hawaii's electricity demand. Four case studies are presented to illustrate that building-equipment retrofitting is a viable and necessary tool for increasing the energy efficiency of buildings. Each case study presents an equipment retrofit project electricity savings with its payback periods, and compares with equivalent electricity capacity and economics PV systems in Honolulu, Hawaii. The case studies show that energy savings from retrofit projects ranged from 28% to 61% for individual equipment retrofits. These results indicate that equipment retrofitting with energy-efficient alternatives is about 50% or more cost-effective than installing PV systems. This is so even when large renewable energy tax incentives provided by the Federal and State Governments are taken into account.

    Full Text Available There are several alternatives to enhance the efficiency of energy usage and to decrease energy losses. Pinch technology is the best method of approach to enhance energy efficiency. Heat exchangers network (HEN of refrigeration unit of ammonia production process was analyzed to use pinch technology to decrease energy usage. The obtained results showed that pinch technology was unsuccessful for the shaft work targeting capabilities. In contrast, it is posed that for optimization of such systems, one should use the combined pinch and exergy analysis (CPEA method. In this analysis CPEA method was used in the system. It was observed that the refrigeration system use cold streams for cooling the hot streams. Therefore, retrofitting the refrigeration cycle without changing the main process is impossible. Some suggestions were made for improving the refrigeration system, such as the use of economizer after cooler, multistage cycle and removal of the 111-FFD3 stream. It was also observed that the exchanger 128-E act as an intercooler and the flashed 110-F, 111-F and 112-F act as an economizer. In addition, ammonia refrigerant was used at three different temperatures of -33,-7 and 13.5 ˚C. Also, eliminated the 111-FFD3 stream bring about 2% reduction in exergy loss.

  8. Increasing the energy conservation awareness using the influential power of a lottery system

    Science.gov (United States)

    Nayak, Amruta Vijay

    This thesis presents an influence maximization-driven approach to promoting energy conservation awareness, with the objective to generate a competitive environment for energy consumption supervision. As consumers are typically reluctant to invest their time and effort in the activities beyond their business, an incentive-based distribution strategy is proposed to encourage consumers to actively take part in energy conservation. The key idea of the thesis lies in leveraging the consumer instincts as a driving factor for spreading positive social influence, via a smart lottery program. In the proposed framework, saving energy automatically increases the consumers' chances of winning the lottery, thereby motivating them to save more, while the smart winner selection will maximize the word-of-mouth effect of the program. The thesis collects and organizes a large body of literature in support of the claim that the spread of awareness in a social network can play a key role in the emergence of energy conscious behavior. It also reports on the findings of a survey conducted to determine the present day consumer perspective toward energy conservation and the level of influence required to motivate them to conserve more energy. Finally, a mathematical model for smart lottery winner selection is presented, and insightful observations are made concerning the properties of optimal solutions to tractable, small problem instances.

    Energy Technology Data Exchange (ETDEWEB)

    Howard, C.D.

    1987-07-01

    Despite the recent drop in world oil prices, the Japanese government is continuing to stress energy conservation, because Japan relies on imports for 85% of its total energy requirements and virtually 100% of its petroleum. Japan stresses long-term developments and sees conservation as an integral part of its 50- to 100-year transition from fossil fuels to nuclear and renewable sources of energy. The Japanese government is targeting new materials, biotechnology, and electronics technologies as the foundation of Japan's economy in the 21st century. Most government research programs in Japan are governed by aggressive timetables and fixed technical goals and are usually guaranteed funding over a 5- to 10-year period. Of the major energy conservation research programs, the best known is the Moonlight Project, administered by the Ministry of International Trade and Industry (MITI), and oriented towards end-use technologies such as Stirling engines and advanced heat pumps. Parts of MITI's Basic Technologies for Future Industries Program involve research in new materials and bioreactors. The Science and Technology Agency's Exploratory Research in Advanced Technologies (ERATO) Program is also investigating these technologies while emphasizing basic research. Other ministries supporting research related to energy conservation are the Ministry of Education, Science, and Culture and the Ministry of Construction. For 1985, government spending for energy conservation research was at least $50 million. Private sector funding of energy conservation research was $500 million in 1984. A brief outline of major programs and key participants is included for several of the most relevant technologies. An overview of Japan's experience in international scientific collaboration is also included.

  14. Oblique superposition of two elliptically polarized lightwaves using geometric algebra: is energy-momentum conserved?

    Science.gov (United States)

    Sze, Michelle Wynne C; Sugon, Quirino M; McNamara, Daniel J

    2010-11-01

    In this paper, we use Clifford (geometric) algebra Cl(3,0) to verify if electromagnetic energy-momentum density is still conserved for oblique superposition of two elliptically polarized plane waves with the same frequency. We show that energy-momentum conservation is valid at any time only for the superposition of two counter-propagating elliptically polarized plane waves. We show that the time-average energy-momentum of the superposition of two circularly polarized waves with opposite handedness is conserved regardless of the propagation directions of the waves. And, we show that the resulting momentum density of the superposed waves generally has a vector component perpendicular to the momentum densities of the individual waves.

  18. The potential estimation and factor analysis of China′s energy conservation on thermal power industry

    International Nuclear Information System (INIS)

    At present, researches about energy conservation are focused on prediction. But there are few researches focused on the estimation of effective input and energy conservation potential, and there has been even no research on energy conservation of thermal power industry of China. This paper will try to fill in such a blank. Panel data on Chinese thermal power industry over 2005–2010 are established, and we adopt the stochastic frontier analysis approach to estimate the energy saving potential of thermal power industry. The results are as follows: (1) the average efficiency of energy inputs in China′s thermal power industry over 2005–2010 was about 0.85, and cumulative energy saving potential equals to 551.04 (Mtce); (2) by improving the non-efficiency factors, the relatively backward inland cities could achieve higher energy saving in thermal power industry; (3) the energy input efficiency of Eastern China Grid is shown to be the highest; (4) in order to realize the energy-saving goal of thermal power industry, one important policy method the government should adopt is to conduct a market-oriented reform in power industry and break the state-owned monopoly to provide incentives for private and foreign direct investment in thermal power sector. -- Highlights: •We adopt SFA model to estimate the coal input efficiency of power sector in China. •We calculate the cumulative energy saving potential equals to 551.04 Mtce. •East China power grid has the highest energy input efficiency. •Some backward inland cities may be the main force for future energy conservation. •Encourage private and foreign direct investment in power sector might be effective

    2015-10-01

    Full Text Available  Wireless Sensor Network (WSN consists of large number of sensor nodes deployed at physical location for sensing & monitoring some physical phenomenon like temperature, humidity, pressure, soil moisture etc. Energy Conservation is one of the prime challenges in WSN owing to the limited battery power and unattended deployment of sensor nodes. There are various techniques motivated towards conserving energy in order to increase overall lifetime of the network. Various schemes and protocols like energy efficient media access control and Routing protocols, Data cycling techniques, Power Management, Sleep Management, Data-driven techniques etc. are used for energy conservation. This paper mainly focuses on exploitation of data-driven techniques in which the sensed data is statistically analyzed in order to find a clue which can save energy requirements. Spatial and temporal correlation between sensor node data can be exploited to propose and efficient data-acquisition technique. The inter-node data association can be measured by calculating the most commonly used metrics for measuring degree of similarity. Finally, data-driven energy conservation technique can be applied if high correlation between inter-node observations is identified.

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.

  4. Macro-economic effects of additional energy conservation in the European Community

    International Nuclear Information System (INIS)

    The aim of the title study is to evaluate the environmental and economic consequences of additional energy conservation in five Western European countries: the Netherlands, the Federal Republic of Germany, the United Kingdom, France and Italy. In the first part of the study the economic effects of a policy, in which additional energy conservation is realized only for the Netherlands, is calculated. In this report the results are presented. The calculated results of the economic effects of a coordinated energy conservation policy in the abovementioned countries will be published in a separate report. The effects of three policy variants will be evaluated: the non-financial policy variant, the shift of the financial burden variant, and the variant in which the levies are not compensated.The starting point for the first variant is an autonomous realization of the energy conservation. The basis of the second variant is that an equal amount of energy can be saved by means of a substantial energy levy. The profits of this levy can be used to reduce the financial burden of labour. For the economic calculations use has been made of the HERMES-model. Every member of the European Community has developed such a macro-economic model. In chapter two the different starting points for the calculations are outlined, with special attention to descriptions of the policy variants, the model-input and the basic projection. In chapter three the economic effects of the policy variants are presented and discussed. In chapter four the energy conservation and the environmental effects of the variants are dealt with. The most important conclusion of this study is that a considerable amount of energy can be saved, which will have positive effects on the economy and the environment. 8 figs., 20 tabs., 6 apps., 32 refs

    Full Text Available Efficient conversion of electrical energy from one form to another has always been a fascinating domain for researchers. Right from the era of mercury arc rectifiers to present AC-DC-AC two stage converters and cycloconverters, efforts are consistently being laid to minimize the losses involved in conversion process. In the present study the AC-AC conversion topology known as Matrix Converter (MC, is modeled using MATLAB. Venturini’s simplified algorithm is used to determine the switch modulation duty cycle. The model is designedfor conversion of 50 Hz input frequency to 100 Hz and 25 Hz, using a simplified switch modulation strategy. The waveforms generated by MATLAB/simulink confirm the reduction of conversion losses by 12% to 15% with use of proposed model as compared to conventional (PWM converters. It is not intended in this study just to list out various works done so for but to establish the brevity of fundamental concept representing the simplified design along with its application areas mainly the VFDs and Wind Energy Conversion Systems (WECS. The model has also been tested for control of induction motor with 100 HZ and 25 Hz output frequencies. The waveforms of changed frequencies and reduced losses confirm the results anticipated at design stage.

    International Nuclear Information System (INIS)

    Energy shortage and environmental catastrophe is the severe problem globally and particularly important for the developing countries like Pakistan. There is a serious need to solve the problem for a sustainable building environment as the building sector has become a major consumer of energy. An attempt has been made for the building professionals and building users for adherence into their design and construction the energy conservation measures to reduce environmental problems more easily after the thorough review of the famous authors' research work and findings in this field. The ultimate aim is the establishment of awareness for the building professionals for delivering sustainable buildings in Pakistan. Through the implementation of design measures to mitigate the urban heat island, the general public can decrease their demand for energy and effectively cool the urban landscape. In addition to the economic benefits, energy conservation leads to reductions in CO/sub 2/ emissions. (author)

  10. All-optical design for inherently energy-conserving reversible gates and circuits

    As energy efficiency becomes a paramount issue in this day and age, reversible computing may serve as a critical step towards energy conservation in information technology. The inputs of reversible computing elements define the outputs and vice versa. Some reversible gates such as the Fredkin gate are also universal; that is, they may be used to produce any logic operation. It is possible to find physical representations for the information, so that when processed with reversible logic, the energy of the output is equal to the energy of the input. It is suggested that there may be devices that will do that without applying any additional power. Here, we present a formalism that may be used to produce any reversible logic gate. We implement this method over an optical design of the Fredkin gate, which utilizes only optical elements that inherently conserve energy.

  12. Light energy conservation processes in Halobacterium halobium cells

    1977-01-01

    Proton pumping driven by light or by respiration generates an electrochemical potential difference across the membrane in Halobacterium halobium. The pH changes induced by light or by respiration in cell suspensions are complicated by proton flows associated with the functioning of the cellular energy transducers. A proton-per-ATP ratio of about 3 is calculated from simultaneous measurements of phosphorylation and the proton inflow. This value is compatible with the chemiosmotic coupling hypothesis. The time course of the light-induced changes in membrane potential indicates that light-driven pumping increases a dark pre-existing potential of about 130 mV only by a small amount (20 to 30 mV). The complex kinetic features of the membrane potential changes do not closely follow those of the pH changes, which suggests that flows of ions other than protons are involved. A qualitative model consistent with the available data is presented.

  13. Returns to residential energy efficiency and conservation measures: A field experiment

    International Nuclear Information System (INIS)

    Residential energy conservation is a key component of contemporary energy and climate change policy in the US and elsewhere. Comparisons of the relative effectiveness of measures aimed at reducing residential energy consumption are made challenging, however, by the endogeneity of technology and energy use decisions. In this paper we describe a novel small-scale field experiment that uses randomized treatments to estimate the returns to three types of energy conservation measures in institutionally owned homes. The results from the experiment indicate considerable reductions in natural gas consumption associated with the installation of attic insulation and the provision of incentives for conservation. The results are supported by observations of ambient indoor temperature data, which show that households receiving incentives significantly reduce their temperature settings—especially when coupled with access to a programmable thermostat. The study will ideally provide guidance for institutions and communities considering energy efficiency measures and for future researchers designing randomized experiments to study residential energy use. - Highlights: • Uses a novel field experiment to test the efficacy of residential energy efficiency measures. • Randomization eliminates endogeneity concerns and rebound effects. • Insulation and financial incentives reduce annual natural gas consumption by nearly 20%. • Reductions are most significant with a combination of incentives and programmable thermostats. • Ambient temperature in homes receiving incentives is as much as 4 degrees F lower than the control

  14. Conflicts in Everyday Life: The Influence of Competing Goals on Domestic Energy Conservation

    Directory of Open Access Journals (Sweden)

    Anneli Selvefors

    2015-05-01

    Full Text Available A common approach for understanding people’s domestic energy behavior is to study the influence of deterministic factors, such as attitudes, norms and knowledge, on behavior. However, few studies have succeeded in fully explaining people’s behavior based on these factors alone. To further the understanding of people’s everyday energy use, a goal-oriented approach based on activity theory has been applied to discuss energy conservation from a multiple goal perspective based on the findings from an interview study with 42 informants. The findings show that the informants used energy to fulfill goals linked to basic needs or desires related to their well-being. Even though the majority of informants had an explicit goal to reduce their energy consumption, many experienced conflicts with other competing goals, which often made energy conservation undesirable or challenging. The findings suggest that actions to reduce energy use will most often not be prioritized if they cannot be integrated into people’s daily life without jeopardizing their possibilities to achieve their primary goals and satisfy their everyday needs. It is thus vital to consider people’s everyday life and the many conflicts they experience when aiming to understand why people do, or do not, prioritize energy conservation during everyday activities.

    This study attempts to identify the optimum social marketing mix for marketing energy conservation behaviour to students in Malaysian universities. A total of 2000 students from 5 major Malaysian universities were invited to provide their preferred social marketing mix. A choice-based conjoint analysis identified a mix of five social marketing attributes to promote energy conservation behaviour; the mix is comprised of the attributes of Product, Price, Place, Promotion, and Post-purchase Maintenance. Each attribute of the mix is associated with a list of strategies. The Product and Post-purchase Maintenance attributes were identified by students as the highest priority attributes in the social marketing mix for energy conservation behaviour marketing, with shares of 27.12% and 27.02%, respectively. The least preferred attribute in the mix is Promotion, with a share of 11.59%. This study proposes an optimal social marketing mix to university management when making decisions about marketing energy conservation behaviour to students, who are the primary energy consumers in the campus. Additionally, this study will assist university management to efficiently allocate scarce resources in fulfilling its social responsibility and to overcome marketing shortcomings by selecting the right marketing mix.

    Cloud computing is a new technology which supports resource sharing on a "Pay as you go" basis around the world. It provides various services such as SaaS, IaaS, and PaaS. Computation is a part of IaaS and the entire computational requests are to be served efficiently with optimal power utilization in the cloud. Recently, various algorithms are developed to reduce power consumption and even Dynamic Voltage and Frequency Scaling (DVFS) scheme is also used in this perspective. In this paper we have devised methodology which analyzes the behavior of the given cloud request and identifies the associated type of algorithm. Once the type of algorithm is identified, using their asymptotic notations, its time complexity is calculated. Using best fit strategy the appropriate host is identified and the incoming job is allocated to the victimized host. Using the measured time complexity the required clock frequency of the host is measured. According to that CPU frequency is scaled up or down using DVFS scheme, enabling energy to be saved up to 55% of total Watts consumption. PMID:27239551
