Sample records for energy-conserving site design

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

    Energy Technology Data Exchange (ETDEWEB)

    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)

  2. Energy-conserving site-design case study, Radisson, New York. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1979-12-01

    Radisson is a 2,950-acre new community currently being developed by the New York State Urban Development Corporation and located in central New York, 12 miles north-west of Syracuse. Case-study sites selected for this project are a 95-acre residential site and the 51-acre Town Center of the new community. Development on the Residential Site is a low-density (2.8 dwelling units/acre) mixture of single-family, townhouse and multi-family units. Development on the Town Center site is a mixture of small-scale commercial use (144,000 sq. ft.) and 330+ multi-family dwelling units. Energy-conserving plans developed for both sites have focused on passive measures to reduce energy use for space heating. Utility-system options have been identified for both sites, but require further study as to feasibility and cost. This report summarizes energy savings and cost differentials due to passive measures incorporated in both the residential and Town Center Plans. The future implementation schedule, also discussed, summarizes the procedures an schedule required for implementation of the passive measures, as well as further study required for the development of utility-system options. 4 tables.

  3. Energy conserving site design: Greenbrier case study, Chesapeake, Virginia. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1980-04-01

    A specific case study of project planning for energy conservation for a major planned unit development at the 3000-acre Greenbrier development site in Chesapeake, Virginia, is summarized. The research suggests that very considerable reductions in energy conservation can be achieved within the confines of private-sector land development and residential construction with increased incremental costs of $200.00 to $3150.00 per dwelling unit. It is hypothesized that energy consumption at Greenbrier can be reduced by one-half with an average annual savings of 21,275 kWh per residential unit, using state-of-the-art technology with careful planning and control. This represents an annual savings $750.00 per unit at the current utility rate of 3.5 cents per kWh. These savings can be achieved through reduction in heating and cooling loads and application of more-efficient heating and cooling of the remaining loads. The reduction in loads are achieved by redesign of the land plan to include a higher percentage of south-facing lots, use of vegetation to modify microclimate, decreases in air infiltration, the use of 2 x 6 framing, better insulation, and the use of an insulated slab-on-grade foundation. Further energy savings can be expected by increased efficiencies in mechanical systems used for space heating and cooling and domestic hot water. When applied to the single-family portion of Greenbrier, containing 541 dwelling units, these options reduce the total end-use energy consumption 54.7%. This reduction represents an annual savings of $432,800.00 for an initial capital investment of $1.7 million.

  4. Energy conserving site design case study, Burke Center, Virginia. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1979-12-01

    The pattern of energy consumption within a modern suburban community, Burke Center, is examined. A variety of actions that could be incorporated to reduce its future energy demands is proposed. Recommendations have been limited to those that are technically feasible today, are reasonably cost-effective, and that should generate little or no market resistance. Findings are that: of the total energy consumed by the Burke Center Community, 57% will go to off-site transportation needs; energy conserving site planning generally coincides with cost-effective site planning; water-to-air heat pumps proved to be the most efficient and cost-effective method available today in the study area for reducing heating and cooling costs in buildings; certain public services such as the collection of solid waste, mail pick-up and delivery, and other routine activities can be made more energy efficient; and the use of available water saving devices in residential and commercial buildings can reduce a community's total utility energy consumption by as much as 20%.

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

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

    Science.gov (United States)

    Drezner, Jeffrey Alan

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

  8. Overview of energy-conserving development planning and design techniques based on five case studies

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-01

    Findings and recommendations are presented of a review of five case studies of ways to conserve energy through development planning and site design in communities. Two approaches were used. In the first approach, a conventional, pre-existing plan was analyzed to determine potential energy use. Once energy-conservation options were identified and evaluated, the conventional plan was modified by employing those options. This approach was used in The Woodlands, Burke Center, and Radisson studies. In the second approach, energy-conservation options are independently identified and evaluated. Those options that passed specific criteria screening were then utilized in developing one or more totally new plans based on energy objectives. This approach was used in Greenbrier and Shenandoah. Radisson is a new town on the outskirts of Syracuse, New York. Greenbrier is a 3000 acre planned community adjacent to Norfolk and Virginia Beach. Shenandoah is a proposed new town in the Atlanta urbanized area. The Woodlands is a new community under development north of Houston. Burke Center is a residential planned unit development in Fairfax County, Virgnia. (MCW)

    Greater energy efficiency can be achieved in existing dwellings thanks to longer lifecycles, slow replacement rates, and technical innovations. Many such dwellings are located in dense urban neighbourhoods, where urban renewal projects are undertaken. Local government can encourage the setting of ambitious goals as a stepping stone to realizing energy efficiency goals that achieve high levels of energy efficiency. The research question which this paper addresses is: to what degree do local governments influence ambitions to conserve energy in existing housing sites? To examine this issue, thirty-three sites in the Netherlands were studied using a quantitative analysis. The results show that collaboration between local authorities and local actors increases the level of ambition to conserve energy. However, local authorities intentionally selected sites with poor energy efficiency, so it would be easy to meet ambitious energy conservation targets. Collaboration between local authorities and local actors turns out to be the key factor in selecting those sites. Moreover, there is little sign of genuine ambition. This article contributes to the debate on energy conservation policies in local housing sites. The study provides starting points for systematic, empirical research into the realisation of energy conservation in existing housing, especially in large-scale refurbishment projects. - Research Highlights: → Local governments encourage the setting of goals to realize energy efficiency goals. → Local authorities intentionally select sites with poor initial energy efficiency performance. → Collaboration with local actors turns out to be a key factor in selecting those sites. →There is little sign of genuine ambition. → Starting points for empirical research into the realisation of energy conservation in housing.

  14. Role of the process designer in the evolution of a technology oriented toward energy conservation

    Energy Technology Data Exchange (ETDEWEB)

    Cassarino, S [CONSER, Rome; Riccardi, R

    1975-01-01

    The increase in energy costs has introduced new stringent boundaries to process engineering, involving the need for more and more advanced calculation techniques and a greater accountability on the part of the process designer for the purposes of a financially effective engineering work. The designing and optimization approaches tending to favor minimum investment decisions for the past are now subjected to a careful critical revision under the pressures of this new reality. The process designer can--through such revision process--bring a substantial contribution of his own to the development of a technology oriented toward energy conservation. In view of these considerations and on the basis of newly emerging trends, some examples are introduced to illustrate certain development opportunities in oil-refining and petrochemical industrial processes. Conventional designs covering a refining plant and an oil fractionating unit are compared in details in this review with alternative patterns to which new designing approaches are applied for the purposes of an optimized energy consumption.

    The risk that a technology will not be implemented or operated as designed is a significant barrier that impedes owners from adopting new energy-conserving building technologies. This results in a feedback loop that encourages decision makers to minimize risk by sticking with the status quo, regardless of the environmental impact. Different technology categories have different levels and types of risks associated with them.This study assigns levels of risk to technologies by tracing a set of envelope systems, lighting designs, lighting controls, HVAC systems, and HVAC controls in a data set of 38 buildings from the design phase through the initial implementation phase. The likelihood that a technology gets implemented and works as expected is assessed, and risk factors for the various technologies are calculated. Explanations for the levels of risk are supported by interviews with third-party reviewers who serve to assist design teams and owners through the construction phase. Results show that daylighting technologies, including dimming daylighting controls, have the highest risk of not being implemented - when otherwise chosen at the selection phase - while roof insulation and lighting designs are most likely to be fully and correctly implemented. Analysis comparing the risk to the energy conservation opportunity indicates the need for prioritization and support during the design and construction phases to realize expected levels of energy conservation. Overall, the interviewees said the most common reasons for lower than expected energy savings are that energy conservation measures were cut-out during value engineering or cut-out due to later decisions that a technology was functionally risky. This research supports large scale investments in energy conservation technologies for buildings through rebate programs, code improvements, and design guides created by large owners. It identifies technologies that need a higher degree of building management effort and

    Berry, L.; Schweitzer, M.; Freeman, E.

    1988-02-01

    This report describes barriers to energy conservation by the elderly. Because of these barriers, they have a greater need for programs that assist with the installation of energy-efficiency improvements. In response to this need, a number of specialized programs are operated for the elderly. This report contains descriptions of 39 energy conservation programs for the elderly. Telephone interviews were conducted with the managers of these programs to identify marketing techniques and organizational structures. Interagency networking, presentations and referrals are the most common methods of recruiting clients. Other marketing techniques in order of the frequency of use are: direct mail, bill inserts, television, radio, printed materials, and telemarketing. Many managers consider word-of-mouth advertising from satisfied clients the most effective form of marketing. Interagency networking and support (financial, structural and in-kind) can offer real advantages in the operation of conservation programs for the elderly. The use of specific marketing techniques is probably less important to success in recruiting clients than the degree of trust potential clients have in the sponsoring organization(s). 4 figs., 10 tabs.

    1984-01-01

    The characteristics predetermined by the method Zellik in designing the electrical furnaces isolated traditionally are comparable with measured values of furnaces in operation. The newest furnaces have been built with isolation resulting in a lower energy consumption. To plot the static characteristics, the furnace was heated up three times to the steady state. In determining the static heat capacity the stored heat was measured by the conventional method. With a view to determining the kinetic heat capacity the furnace was heated up at different rates. On the base of the operating results of the furnace can be stated both the practicability of the method Zellik and the improvement of the characteristics of the furnace isolated with fibrous material.

    Yoda, Kenichi

    1990-01-01

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

  4. Promoting household energy conservation

    International Nuclear Information System (INIS)

    Steg, Linda

    2008-01-01

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

  5. Why not energy conservation?

    International Nuclear Information System (INIS)

    Carlson, Shawn

    2016-01-01

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

  8. 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.

    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

    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.

  20. CO2 reduction through energy conservation

    International Nuclear Information System (INIS)

    1991-05-01

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

    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.

    elements of LTDH networks, particularly when supplying low heat density building areas. The purpose of article IV was to perform simulations and analyses about low-energy DH networks supplying heat to energy-efficient building areas in countries such as Denmark with an extensive existing DH infrastructure, quantify their technical and economic feasibility, and suggest strategies for optimizing their design and operation. Article V deals with the potential and barriers of implementing DH in Canada, where the DH market share is low. Technical-economic feasibility studies for DH networks supplying an urban area in the city of Ottawa were carried out, with particular attention to developing the potential for supplying heat derived from Renewable Energy (RE). Chapter 6 summarises the conclusions. First of all, analysis of the case studies suggests that local authority energy plans should take the opportunities for DH implementation into account, because DH is an essential infrastructure for future, sustainable energy systems. Energy policy should aim at organizing and facilitating the synergy between energy conservation measures and the supply of heat based on RE energy and overcome the traditional competition between the two sectors. It is recommended that Finite Element Method (FEM) models and simulation should be used when designing new pipe geometries and systems. The reliability of the FEM models of DH pipes was validated by means of experimental data and comparison with analytical formulas and data from literature. The calculation method takes into account the temperature-dependency of the thermal conductivity of the insulation foam. It was demonstrated that the asymmetrical insulation of twin pipes in lowtemperature operations leads to 4% to 8% lower heat loss from the supply media pipe than a symmetrical configuration, and at the same time the heat loss from the return media pipe can be kept close to zero. With the use of optimized double-pipe systems (a pair of

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

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

    Design and site selection criteria for the Svalbard oil spill experiments are described. All three experimental sites have coarse and mixed sediment beaches of sand and pebble; within each site wave exposure is very similar; along-shore and across-shore sediment characteristics are also relatively homogeneous. Tidal range is in the order of 0.6 m at neaps, and 1.8 m at springs. All three sites are open to wave action and are ice-free during the experimental period of mid-July to mid-October. Study plots at each site were selected for different treatments from within the continuous stretch of oiled shoreline, with oiled buffer zones between plots and at either end of the oiled zone. Treatments included mixing (tilling), sediment relocation (surf washing) and bioremediation (nutrient enrichment). Measurements and observations were carried out during the summers of 1997 and 1998. The characteristics measured were: wave and wind conditions; beach topography and elevation; sediment grain size distribution; mineral fines size distribution and mineral composition; background hydrocarbons; concentration of oil within experimental plots and the rate of oil loss over time; depth of oil penetration and thickness of the oiled sediment layer; oil concentration and toxicity of near-shore benthic sediments; mineral composition of suspended particulate material captured in sub-tidal sediment traps; and oil-fines interaction in near-shore water samples. 1 fig.

    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.

    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

    Brown, Dale H.

    1976-01-01

    A study was performed to estimate the technical/economic characteristics of a steam power plant (3500 pounds per square inch gauge, 1000 degrees Fahrenheit / 1000 degrees Fahrenheit) with a coal-burning radiant furnace and a wet lime stack gas scrubber to control sulfur emissions. Particulate emissions were controlled by an electrostatic precipitator operating at 300 degrees Fahrenheit. The stack gas from the scrubber was reheated from 125 degrees Fahrenheit to 250 degrees Fahrenheit as a base case, and from 125 degrees Fahrenheit to 175 degrees Fahrenheit as an alternate case. The study was performed on a basis consistent with the General Electric ECAS Phase II evaluation of advanced energy conversion systems for electric utility baseload applications using coal or coal-derived fuels. A conceptual design of the power plant was developed, including the on-site calcination of limestone to lime and the provision of sludge ponds to store the products of flue gas scrubbing. From this design, estimates were derived for power plant efficiency, capital cost, environmental intrusion characteristics, natural resource requirements, and cost of electricity at an assumed capacity factor of 65 percent. An implementation assessment was performed where factors affecting applicability of the conceptual design power plant in electric utility generation systems were appraised. At 250 degrees Fahrenheit and 175 degrees Fahrenheit stack gas temperatures respectively, the plants showed a cost of electricity of 39.8 and 37.0 mills per kilowatt-hours and overall plant efficiencies of 32 percent and 34 percent.

    With the deregulation of the nitrogenous fertilizer industry in Pakistan in 1986, the scenario changed for major energy conservation projects. In addition the government also started escalating the prices of natural gas. At this point they reactivated their major energy conservations projects. The plant was designed prior to the energy crisis period at the point when energy consumption was not a very major consideration. As a result, many of the energy conserving features built into subsequent plants were not included. On the gas turbine side, several changes were required in order to allow that the installation of the HRSG's. The gas turbine had to be upgraded to allow air flow due to the increased back pressure following installation of the HRSG's. Also with the uprate, the gas turbine control system had to be upgraded. The off take ducks for the HRSGs also required a design modification on the gas turbine exhaust to allow for a flanged connection, and the silencers in the exhaust duct had to be removed. The savings of natural gas was as per projections. Presently, with auxiliary firing, the HRSG's are producing 140,000 pph of steam. Their site total gas consumption has reduced by 10.6% or approximately 4 to 4.4 million CFD. In addition, the HRGS's have also provided significant ease of operation and flexibility. Of the three offsite boilers, two have been shut down and only one is operational. (A.B.)

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

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

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

    In late 1985, the Public Advisory Committees to the Environmental Council of Alberta began working toward a draft conservation strategy for Alberta. A prospectus was published and meetings and workshops held, the goal being a conservation strategy in place by 1992. This report is one of a series of discussion papers on relevant sectors such as agriculture, fish and wildlife, tourism, and various specific energy sources. This report focuses on energy use in general in the province, including the role of energy conservation in a conservation strategy, the potential for energy conservation, barriers, actions to encourage conservation, the impacts of conserving energy, and the next steps to take. 3 figs., 1 tab.

    1994-10-01

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

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

  4. Energy conservation through thermally insulated structures

    International Nuclear Information System (INIS)

    Abu-Dayyeh, Ayoub

    2006-01-01

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

    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

  7. Energy conservation in India: a profile

    1992-01-01

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

    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 Ministry of Science and Technology of China organized experts to develop the Internet-based software Counter of Energy Conservation and Emission Reduction to directly measure energy conservation and emission reduction potentials in people's daily lives. Research and testing of the software have been completed, and the software is available to the public on the Internet. The Counter of Energy Conservation and Emission Reduction software is being promoted with the aim of stimulating the public's enthusiasm for energy conservation and emission reduction. The software is of great significance in energy conservation and emission reduction education oriented to elementary and middle school students and community residents, thus changing the lagged public participation of Chinese citizens in energy conservation and emission reduction. The counter can calculate people's energy conservation and emission reduction potential in six aspects of daily life. The user can know his or her value of energy conservation and emission reduction in each aspect by clicking the options in keeping with his or her true daily routines. The user can also know the amounts of energy conservation and emission reduction as well as the potential energy conservation and emission reduction of the whole nation by clicking the Effect Calculation Button. Family life areas mainly include the methods and habits of water use, the use of energy conservation cookers, methods of saving paper, the use of environmental protection products, the habit of home appliance use, and the methods of washing clothing, especially the use of the washing machine with the function of energy conservation. Housing includes the building materials, the heating and cooling systems, the temperature control measures, and the lighting, etc. Heating and cooling times for the house by air conditioner should be reduced. Architects can do a great deal by using energy-efficient building materials and designing houses

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

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

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

  1. Pollution prevention and energy conservation: Understanding the interactions

    International Nuclear Information System (INIS)

    Purcell, A.H.

    1992-01-01

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

    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.

    1983-11-01

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

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

  12. 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.

  14. An analysis of energy conservation measure costs

    International Nuclear Information System (INIS)

    Jones, R.; Ellis, R.; Gellineau, D.

    1990-01-01

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

  17. Energy conservation and the principle of equivalence

    International Nuclear Information System (INIS)

    Haugan, M.P.

    1979-01-01

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

    2012-01-01

    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.

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

    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.

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

Exhaustible primary energy resources such as coal, lignite, oil, and nuclear fuels are being mined out to meet our energy needs. An attempt has been made in this paper to highlight the energy conservation opportunities, energy audit, the relevant Energy Conservation Act 2001 and certain energy saving measures leading to higher productivity followed by a few case study examples. 3 refs.

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

    International Nuclear Information System (INIS)

    1994-01-01

    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.)

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

    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.

    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.

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

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

    2007-01-01

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

    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.

    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.

    From the very origins of numerical hydrodynamics in the Lagrangian work of von Neumann and Richtmyer [83], the issue of total energy conservation as well as entropy production has been problematic. Because of well known problems with mesh deformation, Lagrangian schemes have evolved into Arbitrary Lagrangian-Eulerian (ALE) methods [39] that combine the best properties of Lagrangian and Eulerian methods. Energy issues have persisted for this class of methods. We believe that fundamental issues of energy conservation and entropy production in ALE require further examination. The context of the paper is an ALE scheme that is extended in the sense that it permits cyclic or periodic remap of data between grids of the same or differing connectivity. The principal design goals for a remap method then consist of total energy conservation, bounded internal energy, and compatibility of kinetic energy and momentum. We also have secondary objectives of limiting velocity and stress in a non-directional manner, keeping primitive variables monotone, and providing a higher than second order reconstruction of remapped variables. In particular, the new contributions fall into three categories associated with: energy conservation and entropy production, reconstruction and bounds preservation of scalar and tensor fields, and conservative remap of nonlinear fields. The paper presents a derivation of the methods, details of implementation, and numerical results for a number of test problems. The methods requires volume integration of polynomial functions in polytopal cells with planar facets, and the requisite expressions are derived for arbitrary order.

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

  9. Energy conservation-problems and perspectives for developing nations

    1980-03-15

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

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

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

    In this study, various energy conservation measures (ECMs) on heating, ventilating and air conditioning (HVAC) and lighting systems for a four-storied institutional building in sub-tropical (hot and humid climate) Queensland, Australia are evaluated using the simulation software called DesignBuilder (DB). Base case scenario of energy consumption profiles of existing systems are analysed and simulated first then, the simulated results are verified by on-site measured data. Three categories of ECMs, namely major investment ECMs (variable air volume (VAV) systems against constant air volume (CAV); and low coefficient of performance (COP) chillers against high COP chillers); minor investment ECMs (photo electric dimming control system against general lighting, and double glazed low emittance windows against single-glazed windows) and zero investment ECMs (reset heating and cooling set point temperatures) are evaluated. It is found that the building considered in this study can save up to 41.87% energy without compromising occupancies thermal comfort by implementing the above mentioned ECMs into the existing system.

    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.

    The design of active sites has been carried out using quantum mechanical calculations to predict the rate-determining transition state of a desired reaction in presence of the optimal arrangement of catalytic functional groups (theozyme). Eleven versatile reaction targets were chosen, including hydrolysis, dehydration, isomerization, aldol, and Diels-Alder reactions. For each of the targets, the predicted mechanism and the rate-determining transition state (TS) of the uncatalyzed reaction in water is presented. For the rate-determining TS, a catalytic site was designed using naturalistic catalytic units followed by an estimation of the rate acceleration provided by a reoptimization of the catalytic site. Finally, the geometries of the sites were compared to the X-ray structures of related natural enzymes. Recent advances in computational algorithms and power, coupled with successes in computational protein design, have provided a powerful context for undertaking such an endeavor. We propose that theozymes are excellent candidates to serve as the active site models for design processes.

    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)

  2. PHWR safety: design, siting and construction

    In all activities associated with NPPs viz. siting, design, construction, commissioning and operation, safety is given overriding importance. The safety design principles of PHWRs are based on defence-in-depth approach, physical and functional separation between process and safety systems and also among various safety systems, redundancy to meet single failure criteria and postulation of a number of design basis events for which the plant must be designed. Apart from engineered safety systems, PHWRs have inherent characteristics which contribute to safety. In siting of a NPP, it is required to ensure that the given site does not pose undue radiological hazard to public and the environment both during normal operation as well as during and following an accident condition. For this purpose, all site related external events, both natural and man induced, are assessed for their effect on the plant and are considered as part of the design basis. Possible radiological impact of the NPP on environment and surrounding population is assessed and ensured to be within acceptable limits. During construction phase, it is essential that the NPP be built in accordance with design intent and with required quality of workmanship to ensure that the NPP will remain safe during all states of operation. This is achieved through careful execution and QA activities encompassing all aspects of component fabrication at manufacturer works, civil construction, site erection, assembly, and commissioning. Future trends in nuclear safety will continue to be based on existing principles which have proved to be sound. These will be further strengthened by features such as increasing use of passive means of performing safety functions and a more explicit treatment of severe accidents. (author)

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

    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    1989-01-01

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

    1983-01-01

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

  19. Sewerage force adjustment technology for energy conservation in vacuum sanitation systems

    The vacuum sanitation is the safe and sound disposal approach of human excreta under the specific environments like flights, high speed trains and submarines. However, the propulsive force of current systems is not adjustable and the energy consumption does not adapt to the real time sewerage requirement. Therefore, it is important to study the sewerage force adjustment to improve the energy efficiency. This paper proposes an energy conservation design in vacuum sanitation systems with pneumatic ejector circuits. The sewerage force is controlled by changing the systematic vacuum degree according to the amount of the excreta. In particular, the amount of the excreta is tested by liquid level sensor and mass sensor. According to the amount of the excreta, the relationship between the excreta amount and the sewerage force is studied to provide proper propulsive force. In the other aspect, to provide variable vacuum degrees for different sanitation requirements, the suction and discharge system is designed with pneumatic vacuum ejector. On the basis of the static flow-rate characteristics and the vacuum generation model, the pressure response in the ejector circuit is studied by using the static flow rate characteristics of the ejector and air status equation. The relationship is obtained between supplied compressed air and systematic vacuum degree. When the compressed air is supplied to the ejector continuously, the systematic vacuum degree increases until the vacuum degree reaches the extreme value. Therefore, the variable systematic vacuum degree is obtained by controlling the compressed air supply of the ejector. To verify the effect of energy conservation, experiments are carried out in the artificial excreta collection, and the variable vacuum-degree design saves more than 30% of the energy supply. The energy conservation is realized effectively in the new vacuum sanitation systems with good application prospect. The proposed technology provides technological

    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.

    The energy world crisis of 1973 besides the problems of supplying and the raise of prices also propitiated in various countries, a reaction aimed at the efficient use and conservation of energy and to the application of a common sense architecture: the BIOCLIMATIC ARCHITECTURE, which is based in utilization in the buildings of the alternate energies, such as the wind power, etc. The obtaining natural environmental comfort conditions and the saving and efficient use of energy in the buildings are the fundamental objectives of the BIOCLIMATIC ARCHITECTURE. Under these considerations several passive systems for the thermal control in buildings have been set forth, which have been applied in different climatic regions of the planet. This paper presents and analyzes the potential saving of energy through the implementation of practices such as the installation of artificial high efficiency lighting systems and passive cooling systems for the thermal control of an educational building -the central library of the Universidad Autonoma Metropolitana, Azcapotzalco Unit, located in Mexico City. The objective of this study is aimed at the reduction of the consumption of energy in the library and the attainment of comfortable hygrothermal environment for its occupants. Studies performed during the first stage of the research, have permitted the identification of a excessive energy consumption and lack of comfort hygrothermal conditions and the need of high quality air inside the library. These actions have been focussed to two aspects. The first one is related to the improvement in the operation of the electric installation and in the library lighting. These actions were based in the substitution of lamps, load balancing of the secondary circuits, checking and improvement of the electric insulation a better selectivity of lighting switches installation in the vicinity of windows and areas with greater natural illumination.

    2012-01-01

    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.

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

    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.

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

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

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

  12. 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.

  13. Application of economic principles in energy conservation measures

    1976-01-01

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

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

    This paper explains the development of marine resources utilization system for energy conservation. The conceptual system is designed to take a large amount of deep sea water of 100 thousand to 1 million tons a day, to utilize it from the viewpoint of energy conservation using its coldness and purity characteristics, to then discharge it to the area of the sea in minimizing the environmental effect as well as obtaining effect such as absorption of carbon dioxide gas through cultivation of phyto-plankton. In pump-up technology, a piping system attaching on sea bed or floating with one or multiple constraints is applicable at present to all sites of geographical and oceanographic conditions. In utilization technology, use of deep-sea water as cooling water at a steam power plant, for example, improves generation efficiency by one point or more. In discharge and environment-related technologies, the research revealed that the deep-sea water from 300 m below releases carbon dioxide gas at surface, while photosynthesis can absorb the gas in the process of using nutrition contained in the deep-sea water; therefore, comprehensive examination is necessary taking energy utilization effect into account. Candidate sites were selected in areas of 200 m depth and within 5 km off-shore, with the optimum system examined at each site. (NEDO)

    1976-12-01

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

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

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

  6. Exactly energy conserving semi-implicit particle in cell formulation

    International Nuclear Information System (INIS)

    2017-01-01

    We report a new particle in cell (PIC) method based on the semi-implicit approach. The novelty of the new method is that unlike any of its semi-implicit predecessors at the same time it retains the explicit computational cycle and conserves energy exactly.

    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.

    2003-02-01

    Full Text Available Solid waste landfills are important engineering structures for protection of wastes, decrease of environmental pollution, and especially prevention of soil and water pollution. Solid wastes should conveniently be maintained in landfill areas to control environmental pollution caused by waste disposals. Until the middle of this century clay liners were used for maintenance of waste disposal, but it was observed that these liner systems were insufficient. Today thinner and less permeable liner systems are constructed by using synthetic materials. In this study, by evaluating the waste landfills, site assessment of landfills and construction of natural and synthetic liner systems were summarized respectively, and especially the design properties of these systems were examined intensively. Also, leachate collection and removal facilities, landfill gas collection unites, and final cover unites were evaluated in a detailed way.

A renewable energy online problem based learning (REePBaL) instruction package was developed based on the theory of constructivism and adaptation of the online learning model. This study employed a single group quasi-experimental design to ascertain the changed in students’ behaviour towards energy conservation after underwent the intervention. The study involved 48 secondary school students in a Malaysian public school. ANOVA Repeated Measure technique was employed in order to compare scores of students’ behaviour towards energy conservation before and after the intervention. Based on the finding, students’ behaviour towards energy conservation improved after the intervention.

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

    1983-01-01

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

    Feasibility study was conducted of the project for energy conservation and reduction in greenhouse effect gas emission by introducing the honeycomb type heat storage burner technology to heating furnaces of Vietnam Steel Corporation (VSC). Furnaces for study are the bar mill furnace at Gia Sang plant of TISCO Steelorks, bar mill furnace at Thu Duc plant of SSC Steelworks, billet furnace at new bar mill of SSC Steelworks, slab furnace at new hot strip mill that VSC is now in the planning stage. As a result of the study, the energy conservation amount is 2,900 toe/y at TISCO Steelworks, 2,130 toe/y at SSC Steelworks, and 6,000 toe/y at VSC new hot strip mill, which totaled 11,030 toe/y. The amount of greenhouse effect gas reduction is 9,000 t-CO2/y at TISCO, 6,600 t-CO2/y at SSC, and 18,600 t-CO2/y at VSC, which totaled 34,200 t/y. The total investment amount is 0.23, 0.44, 1.32 and 1.99 billion yen for each. As to the profitability, the internal earning rate is 24%, 86%, 97% and 51% for each, which are all favorable. (NEDO)

    Tramonte, D.J.

    1988-01-01

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

  17. 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.

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

  19. Retrofit energy conservation in residential buildings in southern California

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

    1982-01-01

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

  20. Overview topic paper on mass media energy conservation communications

    Vertinsky, P; Vertinsky, I

    1979-02-01

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

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

    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

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

    The guidelines laid out for the five subjects investigated in this series are to take a holistic view of energy conservation policies by describing the overall system in which they are implemented; provide analytical tools and sufficiently disaggregated data bases that can be adapted to answer a variety of questions by the users; identify and discuss some of the important issues behind successful energy conservation policy; and develop an energy conservation policy in depth. This report contains the design of a specific policy that addresses energy conservation in recreational travel. The policy is denoted as an ''Information System for the National Park Service.'' This work is based on prior examination of the characteristics of the recreational trip and decision making for the recreational experience. The examination revealed which aspects of the recreational travel system needed to be addressed to encourage energy-efficient modal decisions for recreational travel. This policy is briefly described in Section 1, the ''Summary of Initiative.'' A more detailed discussion of the policy follows. The material which led to the policy's formation is developed in Section 2: Importance and Impact of the Recreational Trip; Weekend Travel; The Flowchart: Decision Making for the Recreational Experience; Policy Development for Phase 1 ''Planning the Trip;'' and Objectives and Strategies for ''Planning the Trip.''

    1979-05-02

    A workshop was convened to assist DOE's Technology Assessment Division in evaluating the need to prepare additional environmental- and social-impact assessments of different energy-conservation measures. Attendees participated in a decision-making exercise designed to rank 19 different energy-conservation measures according to their overall potential for achieving important national goals and their ease of implementation. The participants felt that the most-important ranking criteria dealt with questions concerning feasibility (economic, political/institutional, social, and technical) and economic efficiency. Other criteria, such as environmental quality and occupational health and safety received lower weights; possibly because of the widespread belief that most of the conservation measures presented would be environmentally beneficial. In the participants' view, the most-promising and feasible conservation measures include new-building-performance standards, retrofit of existing housing stock, new-appliance-performance standards and increased use of smaller cars. In contrast, conservation options which ranked rather low, such as diesel engines, coal-fired aluminum remelt furnaces, and cupola furnace modifications were expected to have some harmful environmental and health impacts. Most of these impacts are expected to be highly localized and of lesser national concern. Disagreement exists as to the efficacy of funding those projects deemed highly desirable and feasible versus those which are expected to have the greater environmental and social impacts. These differences must be taken into account in the research priorities that are eventually established. While environmental and social impacts of alternative energy-conservation measures may prove to be either harmful or beneficial, neither side should be ignored by the policy maker.

  8. Energy conservation and the residential and commercial sector

    Science.gov (United States)

    1975-01-01

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

    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)

  12. A method of applying two-pump system in automatic transmissions for energy conservation

    Directory of Open Access Journals (Sweden)

    Peng Dong

    2015-06-01

    Full Text Available In order to improve the hydraulic efficiency, modern automatic transmissions tend to apply electric oil pump in their hydraulic system. The electric oil pump can support the mechanical oil pump for cooling, lubrication, and maintaining the line pressure at low engine speeds. In addition, the start–stop function can be realized by means of the electric oil pump; thus, the fuel consumption can be further reduced. This article proposes a method of applying two-pump system (one electric oil pump and one mechanical oil pump in automatic transmissions based on the forward driving simulation. A mathematical model for calculating the transmission power loss is developed. The power loss transfers to heat which requires oil flow for cooling and lubrication. A leakage model is developed to calculate the leakage of the hydraulic system. In order to satisfy the flow requirement, a flow-based control strategy for the electric oil pump is developed. Simulation results of different driving cycles show that there is a best combination of the size of electric oil pump and the size of mechanical oil pump with respect to the optimal energy conservation. Besides, the two-pump system can also satisfy the requirement of the start–stop function. This research is extremely valuable for the forward design of a two-pump system in automatic transmissions with respect to energy conservation and start–stop function.

    Manufactured, or HUD-Code, homes comprise a growing share of the housing stock in the Northwest, as well as nationally. Their relatively low cost has made them especially attractive to lower income families, first-time home-buyers, and retired persons. The characteristics of manufactured home (MH) buyers, the unique energy consumption characteristics of the homes, and their increasing market share make this market an especially critical one for energy consumption and conservation planning in the Northwest. This study relies on extensive, existing survey data and new analyses to develop information that can potentially assist the design of a marketing plan to achieve energy conservation in new manufactured homes. This study has the objective of assisting BPA in the development of a regional approach in which numerous organizations and parties would participate to achieve conservation in new manufactured homes. A previous survey and information collected for this study from regional dealers and manufacturers provide an indication of the energy conservation options being sold to manufactured home buyers in the PNW. Manufacturers in the Northwest appear to sell homes that usually exceed the HUD thermal requirements. Manufacturers typically offer efficiency improvements in packages that include fixed improvements in insulation levels, glazing, and infiltration control. Wholesale costs of these packages range from about $100 to $1500. Typical packages include significant upgrades in floor insulation values with modest upgrades in ceilings and walls. This study identifies trends and impacts that a marketing plan should consider to adequately address the financial concerns of manufactured home buyers.

    The Pulp and Paper Industry in the United States is one of this country`s most energy intensive industries with energy generally being the second or third largest direct operating expense in mill budgets. As such, the industry has long had an effective energy conservation program and has recorded impressive reductions in energy use. It is also one of the two most capital intensive industries in the United States and has a long capital investment cycle, which can be estimated by various techniques at between 20 and 30 years. This paper discusses the estimated impact of the industry`s energy conservation achievements on long term emission reductions of greenhouse gases and will show how technological changes within the industry have impacted past emission reductions and the prospects for continued progress through emerging technologies. The importance to the global competitiveness of the industry of implementing technological change designed to reduce the emission of greenhouse gases within the industry`s normal investment cycle will also be reviewed.

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

    Patterns of adoption and adaptation of a wide range of energy-conserving technologies were observed in 1983-1984. The most widely employed techniques were low-energy lighting and power-factor correction, both of which generate significant savings with minimal alteration to process plant and working methods, are capable of great flexibility in their mode of application, and can be installed independently for small parts of the total plant, in a step-by-step manner. The generally disappointing findings are associated with internal management attitudes to full systematic treatments of energy-cost problems, artificially high barriers to investment, especially in smaller organisations, and widespread lack of commitment to, and understanding of, relevant innovation procedures. Site specific constraints are also important in some older production facilities.

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

    Energy conservation in automotive industry plays a significant role to increase the productivity which reduces the Men, Material, and Machinery. The Automotive industry sector is one of the major sector which works in two or more times of loading of work pieces in welding fixture. It consumes more energy. This project focuses on reduce the energy consumption by applying single time loading of work pieces with minimum number of labours, machine and reduces scrap. Welding fixtures are designed for the components which are difficult to weld in normal way or without any holding unit. The fixture is to be designed for the two wheeler head tube assembly which is to be welded with its companion for its application. It is demonstrated by modelling in Uni-graphics Software and FEA analysis will be done by ANSYS and experimentally products are tested and execute in industry. A code of practice suggested establishing acceptable standard for energy used in Automotive industry.

    This article reports results from a European project, where site characteristics were incorporated into the design process of wind turbines, to enable site-specific design. Two wind turbines of different concept were investigated at six different sites comprising normal flat terrain, offshore...... and complex terrain wind farms. Design tools based on numerical optimization and aeroelastic calculations were combined with a cost model to allow optimization for minimum cost of energy. Different scenarios were optimized ranging from modifications of selected individual components to the complete design...... of a new wind turbine. Both annual energy yield and design-determining loads depended on site characteristics, and this represented a potential for site-specific design. The maximum variation in annual energy yield was 37% and the maximum variation in blade root fatigue loads was 62%. Optimized site...

    Highlights: • Comparison of natural gas and hydrogen fuels for energy conservation in buildings. • Comparison between hydrogen and natural gas fuel cell is performed. • Simulations of building energy supply. • Performance evaluation of two potential gas-power supply scenarios in buildings. • Natural gas fuel cell showed better performance over hydrogen fuel cell. - Abstract: The work provided herein involves a comparison of natural gas and hydrogen fuels for the purpose of energy conservation for buildings via alternative energy generation methodologies. A case study simulation was developed for an average type of commercial building, a nine storey hotel located in Toronto. The two alternative energy source case studies involved the generation of hydrogen via the wind turbine for the fuel cell, and the use of natural gas directly in the steam reforming fuel cell. The simulations for both scenarios were run and the recorded results were compared to the original case study, as well as between the scenarios. To supply for the base load of the building the fuel cells were given the same kW rating for both scenarios. The identification of all existing technologies for hydrogen gas and natural gas has been carried out, and the similar technologies between the two gases were found. For the purpose of realism, only existing purchasable technologies were considered in this paper. Due to the lack of commercially available technologies for hydrogen gas, only a comparison of fuel cell systems could be accomplished. Over the course of the investigative work it was found that when there is no direct supply of hydrogen to the site of utilization, the natural gas fuel cell is beneficial to the building due to its greater efficiency and lower cost. The major drawback for the hydrogen gas fuel cell, when the on-site generation is involved, is that no thermal power extraction systems currently exist for purchase and utilization in the buildings

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

    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.

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

  6. Energy conservation and the environment: conflict or complement

    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.

    2000-01-01

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

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

  10. Environmental protection through energy conservation: A free lunch at last?

    International Nuclear Information System (INIS)

    Ruff, L.E.

    1990-01-01

    A cautious analysis of demand-side management programs is presented. Utility demand-side management (DSM) programs deserve to be given full and careful consideration as a potential way to give consumers better end-use energy services for their money, utilities an edge in an increasingly competitive market, and society a way to reduce the environmental costs of energy production. But in each of these areas, DSM programs offer no free lunches and have no inherent advantages over supply-side programs. If energy conservation makes sense on economic and business grounds, it can meet the standard economic and business tests applied to most of the rest of the economy; it neither requires nor deserves to be exempt from market concepts and disciplines. If utility DSM programs make sense on environmental grounds, they should be able to demonstrate their cost-effectiveness relative to other, primarily supply-side measures society is willing to undertake in order to control environmental effects. Subsidizing DSM measures in the hope that something good will happen far upstream can waste much money and cause disappointment and frustration

  11. Consumer behavior and energy conservation. A policy-oriented field experimental study on the effectiveness of behavioral interventions promoting residential energy conservation

    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.)

    Full Text Available Energy efficiency has become one of the top design criteria for current computing systems. The dynamic voltage and frequency scaling (DVFS has been widely adopted by laptop computers, servers, and mobile devices to conserve energy, while the GPU DVFS is still at a certain early age. This paper aims at exploring the impact of GPU DVFS on the application performance and power consumption, and furthermore, on energy conservation. We survey the state-of-the-art GPU DVFS characterizations, and then summarize recent research works on GPU power and performance models. We also conduct real GPU DVFS experiments on NVIDIA Fermi and Maxwell GPUs. According to our experimental results, GPU DVFS has significant potential for energy saving. The effect of scaling core voltage/frequency and memory voltage/frequency depends on not only the GPU architectures, but also the characteristic of GPU applications.

    2002-01-01

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

  15. Energy conservation for houses and its calculation methods

    Lee, S H

    1981-04-01

    The concept of energy conservation of houses has been developed and began to be applied widely since the first oil crisis. Now we can say definitely that insulating a house is the most effective way of saving energy, and the renewable energy sources are useful only when the demand for space heating and hot water is minimized by insulating. If a house is well insulated, it will need a much smaller, simpler and cheaper heating system. So it will be less efficient to put a solar collector and wind generator on a poorly insulated house. Architects and engineers should have a certain level of practical knowledge of insulation for house to persuade customers using insulating materials and structure. Moreover, it is very essential to amend the existing building codes in order to facilitate this basic necessity. For instance, the Building Regulations of Denmark requires a U-value of 0.4 W/m/sup 2/ degC for heavy weight external wall. If the cavity wall has outer and inner leaf of just normal brick with internal finish of 20 mm cement mortar, which is a typical wall construction for houses in Korea, the thickness of insulation materials to the cavity can be calculated in order to fullfil the U-value of 0.4 W/m/sup 2/ degC in addition to the cavity of the external heavy wall: expanded polyurethane 58 mm, urea formaldehyde foam 67 mm, expanded polystyrene 78 mm, mineral wool 94 mm. The economic feasibility of solar heating system has been calculated. By applying 25% of the year inflation ratio for fuel cost, the result turns out economically comparable with solar heating systems.

    1992-01-01

    The database ICARUS has been used as a starting point to estimate the economical potential for energy conservation in different sectors of the Dutch society. ICARUS is based on research on real energy consuming processes and applications in a number of sub-sectors of the Dutch economy. The present energy conservation potential in the Netherlands is based on energy conservation studies in the Netherlands and other countries. For this article the economical efficient energy conservation potentials in 1992 have been investigated for the Dutch sectors, which do not supply energy. The potentials are determined on the basis of the technical energy conservation potentials for the year 2000, according to the database ICARUS. Two methods were used to extract the economic potential from the technical potential: the method of the Net Market Value and the method of the payback period. From the ICARUS analysis it appears that the technical potential for energy conservation is 479 PJ, which is 28.8% of the primary energy consumption of 1664 PJ in 1985. The economic energy conservation potential is 262 PJ for a payback period of less than five years, which is 17% of the 1985 primary energy consumption. Next to the above-mentioned analysis policy-aimed simulations were carried out for three scenarios to determine economical energy conservation potentials. In one scenario doubled energy prices were used in comparison with the 1991 prices. Another scenario uses the Net Market Value method with a 5% discount rate, and the third scenario uses both parameters

    aiming at achieving the sustainable development in economy and improving living standard of the residents, the government departments in China have strengthened the promotion of green, low-carbon and sustainable development concepts. Under this context, the energy conservation concept is implemented during the implementation of social production and life activities. Currently, in order to ensure the improvement in social energy conservation benefits, the advanced technologies are applied by China's enterprises and residents. This paper, based on this, discusses the development situations of energy conservation in China, and analyzes the application of power electronical technology in the field of energy conservation, hoping to realize the sustainable development of energy conservation cause in China and to gain high yield.

  8. Energy conservation education. Need for coordination; Enoek-undervisning. Behov for koordinering

    Energy Technology Data Exchange (ETDEWEB)

    Novakovic, V

    1994-05-01

    This paper discusses the energy conservation education at university level in Norway. The energy law of 29 june 1990 marks a turning point in the Norwegian energy policy; the market forces are introduced as the most important means of achieving an efficient socio-economic management of the energy resources. The importance of energy conservation is more fully appreciated. The Government can motivate energy conservation in many ways, above all by means of information and training. The position of coordinator for teaching energy conservation was created at NTH (Norwegian Institute of Technology) in 1989. Later a professorship in energy conservation has been established there. The area of activity of the professor is limited to stationary energy use in buildings and industry. 5 refs.

  9. Design Considerations for Multilingual Web Sites

    2005-09-01

    Full Text Available The most powerful marketing, service, and information-distribution tool a library has today is its Web site, but providing Web content in many languages is complex. Before allocating scarce technical and financial resources, it is valuable to learn about writing systems, types of writing, how computers render and represent writing systems, and to study potential problem areas and their possible solutions. The accepted Web standard for presenting languages is Unicode and a full understanding of its history and the coding tools it provides is essential to making appropriate decisions for specific multilingual and internationalization projects. Actual coding examples, as well as a sampling of existing multilingual library services, also serve to illuminate the path of implementation.

    2010-01-01

    To assess the effectiveness of urban energy conservation and GHG mitigation measures, a detailed Long-range Energy Alternatives Planning (LEAP) model is developed and applied to analyze the future trends of energy demand and GHG emissions in Xiamen city. Two scenarios have been designed to describe the future energy strategies in relation to the development of Xiamen city. The 'Business as Usual' scenario assumes that the government will do nothing to influence the long-term trends of urban energy demand. An 'Integrated' scenario, on the other hand, is generated to assess the cumulative impact of a series of available reduction measures: clean energy substitution, industrial energy conservation, combined heat and power generation, energy conservation in building, motor vehicle control, and new and renewable energy development and utilization. The reduction potentials in energy consumption and GHG emissions are estimated for a time span of 2007-2020 under these different scenarios. The calculation results in Xiamen show that the clean energy substitution measure is the most effective in terms of energy saving and GHG emissions mitigation, while the industrial sector has the largest abatement potential.

  11. Modern money theory and ecological tax reform: A functional finance approach to energy conservation

    Science.gov (United States)

    McConnell, Scott L. B.

    This dissertation contributes to heterodox economics by developing a theoretical and policy-relevant link that will promote the conservation of energy while driving the value of the domestic currency. The analysis relies upon the theoretical foundation of modern money theory and functional finance, which states that "taxes-drive-money" where the value of a sovereign nation's currency is imputed through the acceptance by the sovereign nation of the currency in payment of taxation. This theoretical perspective lends itself to various public policy prescriptions, such as government employment policies or the employer of last resort (ELR), which has been discussed at length elsewhere (Wray 1998; Tcherneva 2007, Forstater 2003). This research contributes to this overall program by arguing that the basis for taxation under modern money theory allows public policy makers various alternatives regarding the make-up of the tax system in place. In particular, following functional finance, taxes do not have the sole purpose of paying for government spending, but rather drive the value of the currency and may be designed to perform other functions as well, such as penalizing socially undesirable behavior. The focus in this dissertation is on the amelioration of pollution and increasing energy conservation. The research question for this dissertation is this: what federally implemented tax would best serve the multiple criteria of 1) driving the value of the currency, 2) promoting energy conservation and 3) ameliorating income and wealth disparities inherent in a monetary production economy? This dissertation provides a suggestion for such a tax that would be part of a much larger overall policy program based upon the tenets of modern money theory and functional finance. Additionally, this research seeks to provide an important theoretical contribution to the emerging Post Keynesian and ecological economics dialog.

  12. 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.

    Yavas, U [Univ. of Petroleum and Minerals, Dhahran, Saudi Arabia; Riecken, G

    1981-09-01

    While the US federal government, public utilities and oil companies, among others, have instigated programs to educate the general public on energy conservation and to stimulate an energy-conservation ethic, results of a number of surveys indicate that such efforts in promoting energy conservation have had only limited success. This may be particularly attributable to the low credibility ascribed by the public to energy-information-disseminating sources. This article investigates the feasibility of utilizing opinion leadership, an untried approach, to overcome the credibility problem in disseminating energy information to the general public. 23 references, 4 tables.

    1979-09-01

    An overview of the textile industry and a discussion of energy-conserving technologies currently available at the pilot-demonstration stage are presented. Existing and potential barriers to the adoption of these technologies in the textile industry identified are: economic; technical acceptance; conflict between commitments of capital for compliance with environmental and health regulations and for investment in energy conservation measures; and a lack of information and technical expertise. Possible measures to eliminate barriers to the implementation of energy-conserving technologies are discussed. (MCW)

  17. Impact of Site Elevation on Mg Smelter Design

    Science.gov (United States)

    Baker, Phillip W.

    Site elevation has many surprising and significant impacts on the engineering design of metallurgical plant of all types. Electrolytic magnesium smelters maybe built at high elevation for a variety of reasons including availability of raw material, energy or electric power. Because of the unit processes they typically involve, Mg smelters can be extensively impacted by site elevation. In this paper, generic examples of the design changes required to adapt a smelter originally designed for sea level to operate at 2700 m are presented. While the examples are drawn from a magnesium plant design case, these changes are generically applicable to all industrial plants utilizing similar unit processes irrespective of product.

    Wodrich, D.; Ellingson, D.; Scott, M.; Schade, A.

    1991-01-01

    This report summarizes the Hanford Site methodology used to ensure facility compliance with the natural phenomena design criteria set forth in the US Department of Energy orders and guidance. In particular, the Hanford Site approach to designating a suitable facility open-quotes Usage Category,close quotes is presented. The current Hanford Site methodology for Usage Category designation is based on an engineered feature's safety function and on the feature's assigned Safety Class. At the Hanford Site, Safety Class assignments are deterministic in nature and are based on the consequences of failure, without regard to the likelihood of occurrence. The report also proposes a risk-based approach to Usage Category designation, which is being considered for future application at the Hanford Site. To establish a proper Usage Category designation, the safety analysis and engineering design processes must be coupled. This union produces a common understanding of the safety function(s) to be accomplished by the design feature(s) and a sound basis for the assignment of Usage Categories to the appropriate systems, structures, and components

    The paper describes a methodology for designing a web site for human factor engineers that is applicable for designing a web site for a group of people. Many web pages on the World Wide Web are not organized in a format that allows a user to efficiently find information. Often the information and hypertext links on web pages are not organized into intuitive groups. Intuition implies that a person is able to use their knowledge of a paradigm to solve a problem. Intuitive groups are categories that allow web page users to find information by using their intuition or mental models of categories. In order to improve the human factors engineers efficiency for finding information on the World Wide Web, research was performed to develop a web site that serves as a tool for finding information effectively. The paper describes a methodology for designing a web site for a group of people who perform similar task in an organization.

    1995-06-01

    The US Environmental Protection Agency (EPA) and the National Renewable Energy Laboratory (NREL) for the US Department of Energy (DOE) funded a study to document energy conservation activities and their effects on operation costs, regulatory compliance, and process optimization at several wastewater treatment plants (WWTPS). The purpose of this report is to review the efforts of wastewater treatment Facilities that use residuals as fuels. Case histories are presented for facilities that have taken measures to reduce energy consumption during wastewater treatment. Most of the WWTPs discussed in this report have retrofitted existing facilities to achieve energy conservation. The case studies of energy conservation measures found no effects on the facilities` ability to comply with NPDES permits. Indeed, energy conservation activities enhance environmental compliance in several ways.

  5. Energy conservation in ethanol production from renewable resources and non-petroleum energy sources

    Energy Technology Data Exchange (ETDEWEB)

    1981-03-01

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

    1978-09-01

    The guidelines laid out for the five subjects investigated in this series are to take a holistic view of energy conservation policies by describing the overall system in which they are implemented; provide analytical tools and sufficiently disagregated data bases that can be adapted to answer a variety of questions by the users; identify and discuss some of the important issues behind successful energy conservation policy; and develop an energy conservation policy in depth. Three specific cases reviewed are: the California nonresidential code (1976); the California residential code (1978); and the Farmers Home Administration code (1978). Although these three suits were brought by the building industry, this report also discusses considerations relevant to architects, bankers, and building inspectors. These cases are discussed from three perspectives: (1) objections to the codes explicitly stated in court, (2) industry conditions and practices behind objections stated in court, and (3) general beliefs not stated in court. This discussion focuses on suits intended to limit those building codes which the building industry sees as too strong. However, some energy conservation industries may sue to strengthen codes which they consider too weak. An example of such a case is Polarized Corporation's current suit against the Lighting section of ASHRAE 90-75 (Los Angeles Federal District Court, see Murnane, 1978). (MCW)

  11. Decision support for energy conservation promotion: an analytic hierarchy process approach

    International Nuclear Information System (INIS)

    Kablan, M.M.

    2004-01-01

    An effective energy conservation program in any country should encourage the different enterprises, utilities and individuals to employ energy efficient processes, technologies, equipment, and materials. Governments use different mechanisms or policy instruments such as pricing policy (PP), regulation and legislation (RL), training and education, fiscal and financial incentives (FFI), and R and D to promote energy conservation. Effective implementation of energy conservation policies requires prioritization of the different available policy instruments. This paper presents an analytic hierarchy process (AHP) based modeling framework for the prioritization of energy conservation policy instruments. The use of AHP to support management in the prioritization process of policy instruments for promoting energy conservation is illustrated in this research using the case study of Jordan. The research provided a comprehensive framework for performing the prioritization in a scientific and systematic manner. The four most promising policy instruments for promoting energy conservation in Jordan are RL (37.4%), followed by FFI (22.2%), PP (18.0%), and Training, education and qualification (14.5%). One of the major advantages of the use of the AHP approach is that it breaks a large problem into smaller problems which enables the decision-maker (DM) to have a better concentration and to make more sound decisions. In addition, AHP employs a consistency test that can screen out inconsistent judgements. The presented methodology of the research might be beneficial to DMs in other countries

    In the context of big data age, the energy conservation and emission reduction of transportation is a natural big data industry. The planning, management, decision-making of energy conservation and emission reduction of transportation and other aspects should be supported by the analysis and forecasting of large amounts of data. Now, with the development of information technology, such as intelligent city, sensor road and so on, information collection technology in the direction of the Internet of things gradually become popular. The 3G/4G network transmission technology develop rapidly, and a large number of energy conservation and emission reduction of transportation data is growing into a series with different ways. The government not only should be able to make good use of big data to solve the problem of energy conservation and emission reduction of transportation, but also to explore and use a large amount of data behind the hidden value. Based on the analysis of the basic characteristics and application technology of energy conservation and emission reduction of transportation data, this paper carries out its application research in energy conservation and emission reduction of transportation industry, so as to provide theoretical basis and reference value for low carbon management.

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

    International Nuclear Information System (INIS)

    Lin, Boqiang; Xie, Xuan

    2015-01-01

    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

    Energy conservation is the need of the hour. The first oil shock of 1973 shook up the industrialized nations of the world and awakened them from the sleepy complacency of never-ending oil flow. It made them face the stark reality of the uncertainty in oil supply restoration and the fragility of the trade in oil. This was the time when many countries realized the urgent need for energy conservation. Notably, the wave of energy conservation had struck the Indian intelligentia 3 years earlier when a Fuel Policy Committee was set up by the Government of India in 1970, which finally bore fruits three decades hence in the form of enactment of the much awaited Energy Conservation Act, 2001 by the Government of India. This Act made provisions for setting up of the Bureau of Energy Efficiency, a body corporate incorporated under the Act, for supervising and monitoring the efforts on energy conservation in India. In this article the stages in the historical development of Energy Conservation in India, the Government initiatives taken in this regard and the reasons for the limited success in implementation of conservation policies in the past have been discussed.

    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.

  16. Recommendations for energy conservation standards for new residential buildings - volume 3: Introduction and Background to the Standard Development Effort

    1989-05-01

    The Energy Conservation for New Buildings Act of 1976, as amended, 42 U.S.C Section 6831 et. seq. requires the US Department of Energy to issue energy conservation standards for the design of new residential and commercial buildings. The standards will be mandatory only for the design of new federal buildings, and will serve as voluntary guidelines for the design of new non-federal buildings. This report documents the development and testing of a set of recommendations, from the American Society of Heating, Refrigeration and Air Conditioning Engineers, Inc. (ASHRAE) Special Projects Committee No. 53, designed to provide the technical foundation for the Congressionally-mandated energy standard for new residential buildings. The recommendations have been developed over the past 25 months by a multidisciplinary project team, under the management of the US Department of Energy and its prime contractor, Pacific Northwest Laboratory. Volume III -- Introduction and Background to the Standard Development Effort is a description of the Standard development process and contains the rationale for the general approach and specific criteria contained within the recommendations.

  17. Energy-conserving perennial agriculture for marginal land in southern Appalachia. Final technical report

    Williams, G.

    1982-01-30

    USDA economists predict the end of surplus farm production in the US within this decade. More and more marginal land will be cropped to provide feed for the growing world population and to produce energy. Much of this potential cropland in Southern Appalachia is poorly suited to annual crops, such as corn. Perennial crops are much better suited to steep, rocky, and wet sites. Research was undertaken on the theoretical potentials of perennial species with high predicted yields of protein, carbohydrates, or oils. Several candidate staple perennial crops for marginal land in Southern Appalachia were identified, and estimates were made of their yields, energy input requirements, and general suitabilities. Cropping systems incorporating honeylocust, persimmon, mulberry, jujube, and beech were compared with corn cropping systems. It appears that these candidate staple perennials show distinct advantages for energy conservation and environmental preservation. Detailed economic analyses must await actual demonstration trials, but preliminary indications for ethanol conversion systems with honeylocust are encouraging. It is suggested that short-term loans to farmers undertaking this new type of agriculture would be appropriate to solve cash-flow problems.

    2007-01-01

    Growing concern in Taiwan has arisen about energy consumption and its adverse environmental impact. The current situation of energy conservation in high energy-consuming industries in Taiwan, including the iron and steel, chemical, cement, pulp and paper, textiles and electric/electrical industries has been presented. Since the energy consumption of the top 100 energy users (T100) comprised over 50% of total industry energy consumption, focusing energy consumption reduction efforts on T100 energy users can achieve significant results. This study conducted on-site energy audits of 314 firms in Taiwan during 2000-2004, and identified potential electricity savings of 1,022,656 MWH, fuel oil savings of 174,643 kiloliters (KL), steam coal savings of 98,620 ton, and natural gas (NG) savings of 10,430 kilo cubic meters. The total potential energy saving thus was 489,505 KL of crude oil equivalent (KLOE), representing a reduction of 1,447,841 ton in the carbon dioxide emissions, equivalent to the annual carbon dioxide absorption capacity of a 39,131-ha plantation forest

    Finch, V.A.; King, J.M.

    1982-01-01

    In a study designed to simulate pastoral cattle management practices on marginal and rangelands in Kenya, the physiological adaptations for energy conservation were investigated in African Zebu cattle during a period of undernutrition and water deprivation. In experimental design, the food available to cattle was restricted to 50% of maintenance, watering reduced to every 2 d and distances walked increased from 8 to 16 km/d. Restricting food for nearly 3 months resulted in a 13-14% weight loss in cattle. A 2-day watering regime did not decrease food intake. Cattle that walked the longer distances lost slightly more weight but not significantly more. There was a significant overall reduction in water requirements. Slowing water turnover is seen as adaptive in a water-limited environment. The water turnover rate was determined using the tritiated water dilution technique. Higher solar intensities increased water turnover somewhat, as did extending walking distances. The resting metabolic rate of cattle on restricted food and water was reduced to 30% below that of well-fed and daily watered cattle. This reduction in metabolic requirements would result in conserving energy in dry seasons. Cattle became more thermolabile when offered smaller quantities of food. A heat debt was incurred at night and sweating rates were regulated at low levels during the day, resulting in heat storage. It is suggested that this is a mechanism by which energy is conserved through increasing thermogenesis to maintain body temperature within the normal range

    As the Internet continues to grow as a delivery medium for health information, the design of effective Web sites becomes increasingly important. In this paper, the authors provide an overview of one effective model for Web site design, a user-centered process that includes techniques for needs assessment, goal/task analysis, user interface design, and rapid prototyping. They detail how this approach was employed to design a family health history Web site, Health Heritage . This Web site helps patients record and maintain their family health histories in a secure, confidential manner. It also supports primary care physicians through analysis of health histories, identification of potential risks, and provision of health care recommendations. Visual examples of the design process are provided to show how the use of this model resulted in an easy-to-use Web site that is likely to meet user needs. The model is effective across diverse content arenas and is appropriate for applications in varied media. PMID:12087113

    This report describes options for monitoring the status and population trends of the golden eagle (Aquila chrysaetos) within the Desert Renewable Energy Conservation Plan (DRECP) area of Southern California in maintaining stable or increasing population in the planning area. The report profiles the ecology of golden eagles in the region and provides a range of potential sampling options to address monitoring needs and objectives. This approach also focused on links between changes in human land-use, golden eagle nesting and foraging habitat conditions, and population dynamics. The report outlines how monitoring data from demographic, prey, and habitat studies were used to develop a predictive demographic model for golden eagles in the DRECP area. Results from the model simulations suggest increases in renewable energy development could have negative consequences for population trajectories. Results also suggest site-specific conservation actions could reduce the magnitude of negative impacts to the local population of eagles. A monitoring framework is proposed including: (1) annual assessments of site-occupancy and reproduction by territorial pairs of golden eagles (including rates at which sites become colonized or vacated over time); (2) estimates of survival, movements, and intensity of use of landscapes by breeding and non-breeding golden eagles; (3) periodic (conducted every two to four years) assessments of nesting and foraging habitats, prey populations, and associations with land-use and management activities; and (4) updating the predictive demographic model with new information obtained on eagles and associated population stressors. The results of this research were published in the Journal of Rapture Research, Wiens, David,Inman, Rich D., Esque, Todd C., Longshore, Kathleen M. and Nussear, Kenneth (2017).

    This report summarizes the Hanford Site methodology used to ensure facility compliance with the natural phenomena design criteria set forth in the US Department of Energy Orders and guidance. The current Hanford Site methodology for Usage Category designation is based on an engineered feature's safety function and on the feature's assigned Safety Class. At the Hanford Site, Safety Class assignments are deterministic in nature and are based on teh consequences of failure, without regard to the likelihood of occurrence. The report also proposes a risk-based approach to Usage Category designation, which is being considered for future application at the Hanford Site. To establish a proper Usage Category designation, the safety analysis and engineering design processes must be coupled. This union produces a common understanding of the safety function(s) to be accomplished by the design feature(s) and a sound basis for the assignment of Usage Categories to the appropriate systems, structures, and components. 4 refs., 9 figs., 1 tab

    WSN (Wireless Sensor Network) is an emerging technology that has unlimited potential for numerous application areas including military, crisis management, environmental, transportation, medical, home/ city automations and smart spaces. But energy constrained nature of WSNs necessitates that their architecture and communicating protocols to be designed in an energy aware manner. Sensor data collection through clustering mechanisms has become a common strategy in WSN. This paper presents a survey report on the major perspectives with which energy conservation mechanisms has been proposed in dynamic cluster based WSNs so far. All the solutions discussed in this paper focus on the cluster based protocols only.We have covered a vast scale of existing energy efficient protocols and have categorized them in six categories. In the beginning of this paper the fundamentals of the energy constraint issues of WSNs have been discussed and an overview of the causes of energy consumptions at all layers of WSN has been given. Later in this paper several previously proposed energy efficient protocols of WSNs are presented. (author)

    The aim of this study is to investigate the Taiwanese public's perceptions of tensions between the implementation of an energy policy and the practice of traditional culture. The energy policy calls for public actions to conserve energy and reduce carbon emissions. The research participants are 94 people, selected by balancing sexes, ages, and residential areas, from a wide range of vocations. The research data were collected by semi-structured interview with the participants individually. Interview questions were designed to elicit the participants' constructs, beliefs, behaviours, and tensions in relation to energy policy and traditional culture. Data analysis was performed based on a qualitative methodology by the procedure of open coding, theme finding, constant comparison, and theory generation. The analysis identifies four tensions: (1) tensions in knowledge bases between energy conservation and carbon reduction, (2) tensions in lifestyles between having and being, (3) tensions in social systems between authority and conformity, and (4) tensions in creation boundaries between technology and nature. The themes underlying the four tensions are uncertainty, pleasure, power, and control, respectively. Solutions to the four tensions may include practical knowledge, pragmatic idealism, hierarchical collaboration, and sustainable innovation. - Highlights: ► Tensions occur between energy policy and traditional culture. ► Tensions occur in knowledge, life, society, and creation in Taiwan. ► The themes of the four tensions are uncertainty, pleasure, power, and control

    Urbanek, A.

    An energy conservation house is the winner out of a total of 60 designs and is displayed at the prefabricated-house exhibition at Bad Vilbel. Similar to Socrates' building in antiquity, this house constitutes a triangle both perpendicularly and horizontally opening its largest possible surface to the South. Any 'residual heat' needed for the Northern roof planted over, is supplied by the air collectors either directly or by means of a high-performance heat pump via heating of the controlled feed air through a novel air floor heating installation while removing energy, too, from the exhaust air through heat recovery. In a survey supported by photos of models and buildings, lay-out plans and connector diagrams of energy supply, technical details of the heat protection concept (aerated concrete for walls, ceilings, roofing structures) and the energy concept with air collectors are described along with a discussion of heat pump operation, the novel air floor heating system and the solar cycle control system. Every room has a miniature heat exchanger allocated in the central unit so that re-heated air can be demanded via the separate room thermostat depending on reflow-air temperature.

    Industrial boiler is one of the most energy-consuming equipments in china, the annual consumption of energy accounts for about one-third of the national energy consumption. Industrial boilers in service at present have several severe problems such as small capacity, low efficiency, high energy consumption and causing severe pollution on environment. In recent years, our country in the big scope, long time serious fog weather, with coal-fired industrial boilers is closely related to the regional characteristics of high strength and low emissions [1]. The energy-efficient and emission-reducing of industry boiler is of great significance to improve China’s energy usage efficiency and environmental protection. Difference in thermal equilibrium theory is widely used in boiler design, exergy analysis method is established on the basis of the first law and second law of thermodynamics, by studying the cycle of the effect of energy conversion and utilization, to analyze its influencing factors, to reveal the exergy loss of location, distribution and size, find out the weak links, and a method of mining system of the boiler energy saving potential. Exergy analysis method is used for layer combustion boiler efficiency and pollutant emission characteristics analysis and evaluation, and can more objectively and accurately the energy conserving potential of the mining system of the boiler, find out the weak link of energy consumption, and improve equipment performance to improve the industrial boiler environmental friendliness.

    Full Text Available Active suspension has not been popularized for high energy consumption. To address this issue, this paper introduces the concept of a new kind of suspension. The linear motor is considered to be integrated into an adjustable shock absorber to form the hybrid active semiactive suspension (HASAS. To realize the superiority of HASAS, its energy consumption and regeneration mechanisms are revealed. And the system controller which is composed of linear quadratic regulator (LQR controller, mode decision and switch controller, and the sliding mode control based thrust controller is developed. LQR controller is designed to maintain the suspension control objectives, while mode decision and switch controller decides the optimal damping level to tune motor thrust. The thrust controller ensures motor thrust tracking. An adjustable shock absorber with three regulating levels to be used in HASAS is trial produced and tested to obtain its working characteristics. Finally, simulation analysis is made with the experimental three damping characteristics. The impacts of adjustable damping on the motor force and energy consumption are investigated. Simulation results demonstrate the advantages of HASAS in energy conservation with various suspension control objectives. Even self-powered active control and energy regenerated to the power source can be realized.

    Discussions have been given on energy conservation, and reduction in greenhouse gas emission through efficiency improvement at the Uong Bi coal burning power plant in Vietnam. The Uong Bi power plant, which has become using coal of lower quality than the design value, has had incomplete combustion, resulting in increase of unburned components in ash, and decrease of the boiler efficiency to 65 to 70%. Clinker hopper troubles have been occurring frequently, causing plant shutdown at a number of times. The turbine efficiency also shows as very low value as 26 to 27%. The plan has envisaged replacement of combustion parts of the boilers, withdrawal and replacement of the turbine generation systems, new installation of electric dust collectors, modification of the ash treatment system, additional installation of the re-circulation system, new installation of waste water treatment facilities, and modification of the waste water treatment equipment in the plant premises. As a result of the discussions, the annual energy saving quantity was found to be 62,936 tons of crude oil equivalent for the case where only one turbine is renewed, and 93,298 tons for the case where both of the two turbines are renewed. The annual reduction quantity of the greenhouse gas emission was found to be 251,215 tons and 372,402 t-CO2, respectively. (NEDO)

    Full Text Available Technological advances have led to the emergence of wireless sensor nodes in wireless networks. Sensor nodes are usually battery powered and hence have strict energy constraints. As a result, energy conservation is very important in the wireless sensor network protocol design and the limited power resources are the biggest challenge in wireless network channels. Link adaptation techniques improve the link quality by adjusting medium access control (MAC parameters such as frame size, data rate, and sleep time, thereby improving energy efficiency. In this paper we present an adaptive packet size strategy for energy efficient wireless sensor networks. The main goal is to reduce power consumption and extend the whole network life. In order to achieve this goal, the paper introduces the concept of a bounded MAB to find the optimal packet size to transfer by formulating different packet sizes for different arms under the channel condition. At the same time, in achieve fast convergence, we consider the bandwidth evaluation according to ACK. The experiment shows that the packet size is adaptive when the channel quality changes and our algorithm can obtain the optimal packet size. We observe that the MAB packet size adaptation scheme achieves the best energy efficiency across the whole simulation duration in comparison with the fixed frame size scheme, the random packet size and the extended Kalman filter (EKF.

    A methodology is proposed to compute the design spectra for a NPP site. Near field earthquakes are included by using an appropriately scaled sample of response spectra. Site effects are considered through a probabilistic site response analysis in the frequency domain which considers nonlinear behaviour of soils. The uncertainties of the soil shear modulus, G, are introduced by using Rosenblueth's point estimates. Strong motion duration is treated by using sensitivity analysis. The procedure is applied to a NPP site and the results are: a) the USNCR R.G.1.60 underestimate the spectral amplitudes for frequencies of interest; b) the omission of the uncertainties on the G leads to under or over-estimate the spectral amplitudes at certain frequency bands; c) the effect of considering the actual strong motion duration instead of an average value is to reduce the peak spectral amplitudes by a ten per cent.

    This pilot study evaluated the effectiveness of energy conservation training to help post-therapy cancer survivors manage their fatigue. Twelve post-therapy cancer survivors were randomly assigned to an energy conservation training or usual care control (6 in each group). Participants in the intervention group received 1 to 2 hours of individual, face-to-face energy conservation training from an occupational therapist followed by once-a-week telephone monitoring sessions in the subsequent three weeks. Participants in the control group received standard care from their oncologist. Analysis of pre- and post-training data from the Piper Fatigue Scale (PFS) revealed significant reduction only in the sensory subscale of the PFS (Z = 2.21; p = 0.027) for the intervention group; but no significant reduction in the four subscale or total scores of the PFS for the control group. Findings demonstrate partial support for the effectiveness of energy conservation training in helping post-therapy cancer survivors manage their fatigue. Energy conservation training seems to be a viable strategy for managing cancer-related fatigue, though its efficacy is modest. Incorporating specific energy restoration strategies such as relaxation and meditation for future research may help advance the growing body of knowledge in symptom management for post-therapy cancer survivors.

    Mandatory or voluntary energy-efficiency standards for new or existing buildings can play an important role in a national program aimed at promoting energy conservation. Building codes and standards can provide a degree of control over design and building practices throughout the construction process, and encourage awareness of energy-conscious design. Studies in developed countries indicate that efficiency standards can produce energy reductions on the order of 20 to 40% or more. Within ASEAN, analyses of the savings potential from the proposed standards suggest that if implemented, these standards would produce savings over current new design practice of 19% to 24%. In this volume we provide an overview of the ASEAN-USAID project aimed at promulgating standards for energy efficiency in commercial buildings. The process of developing and implementing energy-efficiency standards for buildings can be subdivided into two key components: policy development; and technical and economic analysis. Each of these involves a number of steps and processes, as outlined in Figure 1-1. This volume describes the technical and economic analyses used to develop the proposed energy efficiency standards for four countries (Malaysia, Thailand, the Philippines, and Indonesia), and to refine an energy standard existing in Singapore since 1979. Though oriented toward the ASEAN region, the analysis methods described here are applicable in a range of settings, provided appropriate modifications are made for local building construction, climatic, economic, and political conditions. Implementation issues are not specifically addressed here; rather this volume is oriented towards the analytical work needed to establish or revise an energy standard for buildings.

    The Southern Shipbuilding Corporation (SSC) site is an inactive barge/ship manufacturing and repair facility situated on approximately 54 acres in Slidell, St. Tammany Parish, Louisiana. Two unlined surface impoundments (North and South impoundments) are situated on the northwest portion of the site and are surrounded on three sides by Bayou Bonfouca. These impoundments are the sources of carcinogenic polynuclear aromatic hydrocarbon (CPAH) contamination at the site. Inadequate containment has resulted in the release of impoundment wastes into the bayou. To evaluate potential response alternatives for the site, an Engineering Evaluation/Cost Analysis (EE/CA) field investigation was conducted from July through October 1994. A two phase sampling approach was used in combination with innovative and traditional sampling techniques, field screening technologies, and exploitation of the visual characteristics of the waste to determine the extent of waste migration with limited off-site laboratory confirmation. A skid-mounted mobile drilling unit, secured to a specialized sampling platform designed for multiple applications, was used for collection of sediment cores from the bayou as well as tarry sludge cores from the impoundments. Field screening of core samples was accomplished on site using an organic vapor analyzer and a total petroleum hydrocarbon (TPH) field analyzer. Pollutants of concern include metals, cyanide, dioxin, and organic compounds. This paper presents details on the sampling design and characterization techniques used to accomplish the EE/CA field investigation

    In November, 1985, Hanford was selected by the Department of Energy (DOE) as the preferred site for a full-scale test of the integrated nuclear subsystem for SP-100. The Hanford Engineering Development Laboratory, operated by Westinghouse Hanford Company, was assigned as the lead contractor for the Test Site. The nuclear subsystem, which includes the reactor and its primary heat transport system, will be provided by the System Developer, another contractor to be selected by DOE in late FY-1986. In addition to reactor operations, test site responsibilities include preparation of the facility plus design, procurement and installation of a vacuum chamber to house the reactor, a secondary heat transport system to dispose of the reactor heat, a facility control system, and postirradiation examination. At the conclusion of the test program, waste disposal and facility decommissioning are required. The test site must also prepare appropriate environmental and safety evaluations. This paper summarizes the preliminary design requirements, the status of design, and plans to achieve full power operation of the test reactor in September, 1990

    Based on experience and many years of research in the field of energy use, ways of solving methodological problems of energy conservation and environmental protection in Poland have been proposed. These problems were examined as related to the conditions of centrally-planned to market economy, with due considerations for experience of highly developed countries. The paper also presents criteria and functions for qualification of the results of energy conservation and environment protection. It emphasises the importance of direct economical criteria and non-economical criteria when solving ecology-related problems. In this stage the proposals outlined in the paper have only a theoretical character. They could be developed further as the results of the research work in the field of energy conservation and ambient media (air, water, soil) protection are brought to a common denominator. (author)

    It is pointed out that New Zealand industry has been identified as putting little effort into energy conservation. An energy conservation campaign in industry to increase efficiency and reduce wastage could have major benefits for New Zealand as a whole. Little progress in implementing energy conservation techniques in industry is apparent at present. Business decisions are in the main motivated by profits. Because of the low place of energy in industry's costs of production, seen as a single factor, it hardly rates greater priority over other established production costs. A need to integrate energy costs and material costs is apparent. The need for education is obvious, now, with cheap and limitless energy no longer existing.

    2015-01-01

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

  6. Status of small reactor designs without on-site refuelling

    International Nuclear Information System (INIS)

    2007-01-01

    There is an ongoing interest in member states in the development and application of small and medium sized reactors (SMRs). In the near term, most new NPPs are likely to be evolutionary designs building on proven systems while incorporating technological advances and often the economics of scale, resulting from the reactor outputs of up to 1600 MW(e). For the longer term, the focus is on innovative designs aiming to provide increased benefits in the areas of safety and security, non-proliferation, waste management, resource utilization and economy, as well as to offer a variety of energy products and flexibility in design, siting and fuel cycle options. Many innovative designs are reactors within the small-to-medium size range, having an equivalent electric power less than 700 MW(e) or even less than 300 MW(e). A distinct trend in design and technology development, accounting for about half of the SMR concepts developed worldwide, is represented by small reactors without on-site refuelling. Such reactors, also known as battery-type reactors, could operate without reloading and shuffling of fuel in the core over long periods, from 5 to 25 years and beyond. Upon the advice and with the support of IAEA member states, within its Programme 1 'Nuclear Power, Fuel Cycle, and Nuclear Science', the IAEA provides a forum for the exchange of information by experts and policy makers from industrialized and developing countries on the technical, economic, environmental, and social aspects of SMRs development and implementation in the 21st century, and makes this information available to all interested Member States by producing status reports and other publications dedicated to advances in SMR technology. The objective of this report is to provide Member States, including those just considering the initiation of nuclear power programmes and those already having practical experience in nuclear power, with a balanced and objective information on important development trends and

    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.

    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.

    1991-01-01

    Neurotransmitter binding sites, such as receptors, neuronal uptake systems, and vesicular uptake systems, are important targets for new radiopharmaceutical design. Selection of potential radioligands can be guided by in vitro laboratory data including such characteristics as selectivity and affinity for specific binding sites. However, development of PET radiotracers for use in vivo must include considerations of in vivo pharmacokinetics and metabolism. Introduction of potential radioligands is further narrowed by the demands of the radiochemical synthesis, which must produce radioligands of high chemical and radiochemical purity and of high specific activity. This paper will review examples of previous and current attempts by radiopharmaceutical chemists to meet these demands for new positron emitter-labeled radioligands for PET studies of a wide array of neurotransmitter binding sites

    NEDO (New Energy and Industrial Technology Development Organization), from the viewpoint that the development and popularization of energy conservation technologies are extremely important as energy conservation measures, collected energy related primary information from 12 Asian countries including Japan for the development and popularization of energy conservation technologies, and has constructed a database NEDO/DB. NEDO is now propelling forward its efforts to popularize the database. For popularizing NEDO/DB in Vietnam and for rendering the people conscious of energy conservation, NEDO dispatched some lecturers to an energy conservation seminar sponsored by the Vietnamese Government. The importance of energy conservation promoting measures was highlighted at the seminar. NEDO's approach to AIJ (activities implemented jointly) and CDM (clean development mechanism) was described at the seminar, and a lecture meeting was held to explain NEDO/DB and to teach how to use the database.

    Full text: In June 1994, there was an incident of flooding at Kakrapar Atomic Power Station (KAPS) due to combination of heavy rains and mechanical failure in the operation of gates at the adjoining weir. An indepth review of the incident was carried out and a number of flood protection measures were recommended and were implemented at site. As part of this review, a safety analysis was also done to demonstrate reactor safety with a series of failures considered in the flood protection features. For each inland NPP site, as part of design, different flood scenarios are analysed to arrive at design basis flood (DBF) level. This level is estimated based on worst combination of heavy local precipitation, flooding in river, failure of upstream/downstream water control structures

    1994-01-01

    The Fultz Landfill Superfund (Fultz) site is a 30-acre hazardous waste landfill located near Byesville, Ohio. The site is approximately 75 miles east of Columbus and 3 miles southwest of Cambridge, the largest city in Guernsey County, Ohio. The landfill is situated on the north slope of a ridge that overlies abandoned coal mines in the Upper Freeport Coal seam. The north half of the landfill lies in an unreclaimed strip mine in the Upper Freeport Coal seam, where saturated portions of surface mine spoils and natural soils form the ''shallow aquifer''. The south half of the landfill lies 40 to 50 feet (ft.) above an abandoned, flooded deep mine in the same coal seam. The flooded deep mine forms an aquifer referred to as the ''coal mine aquifer''. This paper presents the results of design studies completed by PRC Environmental Management, Inc. (PRC), during 1993, and the remedial design (RD) of the components specified by the US Environmental Protection Agency (EPA) Record of Decision (ROD) for the Fultz site (EPA 1991). The remedy specified in the ROD includes a multilayer landfill cap that is compliant with Resource Conservation and Recovery Act (RCRA) Subtitle C guidelines, a leachate collection and groundwater extraction and treatment system, and stabilizing mine voids underlying the southern portion of the site. Vinyl chloride is the only contaminant exceeding a maximum contaminant limit (MCL) in the coal mine aquifer

    consumers in demand response programs. The chapter looks at how the confluences of consumer strategic behavior, technology and price incentives in demand response lead to conflicting outcomes. Demand response has become an important tool for utilities to manage load during peak periods. While the effects of demand response programs on peak load reductions are well studied and intuitive, assessments typically fail to recognize the potential for off-peak behavioral responses that may mitigate the total benefits of the program. Using smart meter consumption data on residential air conditioning units enrolled in a direct load control program, this paper examines changes in consumption prior to and after curtailment events. The manuscript rigorously estimates both peak and off peak changes in consumption to better understand net benefits of DR programs. We examine Pacific Gas and Electric's (PG&E) SmartAC program, which is designed to reduce peak cooling load by directly controlling air conditioning units of participants. Usually, program evaluation uses the availability of a control group to obtain unbiased estimates of program impacts. However, we do not have the luxury of a control group in our data. Instead we estimate unit-specific non-linear consumption models and then compare load on event days to predicted load. Importantly, we use data from the summer 2007 training period from a stratified random sample of 294 participating AC units. In contrast to subsequent summers and normal DR designs, during the training period curtailment days were called for many different temperature levels, not just the hottest days. This aspect means we are not predicting out of sample, and we can have greater confidence in our econometric evidence. Our methodology is validated by a falsification test in which we find no changes in consumption during peak or off-peak times on non-curtailment days that match the temperature and timing profile of actual curtailment days. Several key results

    This study describes a district-level energy intervention and conservation program designed and implemented with the help of community stakeholders, which include students and staff of an educational institution, the National University of Singapore, a local non-governmental environmental group in Singapore and the district government. The program – known formally as the Eco-living Program – was funded by the district government and implemented in the Hong Kah North Residential Council in the south western part of Singapore. The research objectives are three-fold: (1) compare the effectiveness of different intervention methods, based on self-reported behavior scores and actual electricity reduction; (2) investigate how behavior and electricity consumption are influenced by values, situational and psychological factors; (3) assess the effectiveness of different methods of intervention and provide recommendations for improvement. It was found that a combined use of leaflets and stickers resulted in highest (that is, 15.8%) reduction in average consumption. Ease of practicing the recommended energy conservation actions is a strong motivators to change energy consumption behavior. This program exemplifies the important role that community-initiated bottom-up programs can play in promoting sustainable consumption with the financial support from the local (district) government. - Highlights: ► Energy intervention was implemented on 151 households. ► Outreach methods included stickers, leaflets and counseling. ► Self-reported behavioral and actual reductions were recorded. ► Actual reduction was correlated to large housing apartments not in control group. ► Intervention program found to be cost effective and promote stakeholder engagement

    1992-06-01

    This volume reports on research in the area of energy conservation technology applied to commercial buildings in the Association of Southeast Asian Nations (ASEAN) region. Unlike Volume I of this series, this volume is a compilation of original technical papers prepared by different authors in the project. In this regard, this volume is much like a technical journal. The papers that follow report on research conducted by both US and ASEAN researchers. The authors representing Indonesia, Malaysia, Philippines, and Thailand, come from a range of positions in the energy arena, including government energy agencies, electric utilities, and universities. As such, they account for a wide range of perspectives on energy problems and the role that technology can play in solving them. This volume is about using energy more intelligently. In some cases, the effort is towards the use of more advanced technologies, such as low-emittance coatings on window glass, thermal energy storage, or cogeneration. In others, the emphasis is towards reclaiming traditional techniques for rendering energy services, but in new contexts such as lighting office buildings with natural light, or cooling buildings of all types with natural ventilation. Used in its broadest sense, the term ``technology`` encompasses all of the topics addressed in this volume. Along with the more customary associations of technology, such as advanced materials and equipment and the analysis of their performance, this volume treats design concepts and techniques, analysis of ``secondary`` impacts from applying technologies (i.e., unintended impacts, or impacts on parties not directly involved in the purchase and use of the technology), and the collection of primary data used for conducting technical analyses.

  18. DEMONSTRATION OF THE DOE INTERIM ENERGY CONSERVATION STANDARDS FOR NEW FEDERAL RESIDENTIAL BUILDINGS

    In accordance with federal legislation, the U.S. Department of Energy (DOE) has sponsored a study to demonstrate use of its Interim Energy Conservation Standards for New Federal Residential Buildings. The demonstration study was conducted by DOE and the Pacific Northwest Laboratory (PNL). The demonstration is the second step in a three-step process: I) development of interim standards, 2) demonstration of the interim standards, and 3) development of final standards. The standards are mandatory for federal agency housing procurements. Nevertheless, PNL found at the start of the demonstration that agency use of the interim standards had been minimal. The purpose of the standards is to improve the energy efficiency of federal housing and increase the use of nondepletable energy sources. In accordance with the legislation, the standards were to be performance-based rather than prescribing specific energy conservation measures. To fulfill this aspect of the legislation, the standards use a computer software program called COSTSAFR which generates a point system that individualizes the standards to specific projects based on climate, housing type, and fuel costs. The standards generate minimum energy-efficiency requirements by applying the life-cycle cost methodology developed for federal projects. For the demonstration, PNL and DOE chose five federal agency housing projects which had been built in diverse geographic and climate regions. Participating agencies were the Air Force, the Army (which provided two case studies), the Navy, and the Department of Health and Human Services. PNL worked with agency housing procurement officials and designers/architects to hypothetically apply the interim standards to the procurement and design of each housing project. The demonstration started at the point in the project where agencies would establish their energyefficiency requirements for the project and followed the procurement process through the designers' use of the point

  11. Implementing China's national energy conservation policies at state-owned electric power generation plants

    International Nuclear Information System (INIS)

    Zhao Xiaofan; Ortolano, Leonard

    2010-01-01

    China's 11th Five-Year Guideline identified energy conservation as one of the country's fundamental policies and established a mandatory target: 20% reduction in national average energy intensity by 2010. Despite the various policies, laws, and administrative reforms to support energy conservation, China fell behind schedule for meeting its conservation targets in 2006 and 2007. Using a combination of available literature and an interview-based case study, this paper examines the implementation of energy conservation and investigates impediments to achieving China's conservation goal in the electric power generation sector. Three key impediments are detailed: (1) municipal governments' incentives to overlook conservation-related central directives primarily because of budget pressures linked to financial decentralization, (2) procedural obstacles in the form of time required to obtain project approvals for high-efficiency power generation units, and (3) financial obstacles making it difficult for power generation enterprises to raise capital for energy conservation projects. An interview-based case study of a state-owned coal-fired electric power generation company demonstrates the influence of the aforementioned obstacles. While procedural obstacles are notable, they can be managed. However, electricity pricing reforms and/or stronger subsidy programs will be needed to address the financial obstacles facing Chinese power generation companies.

    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.

  6. Applying the Theory of Planned Behavior in Predicting Proenvironmental Behaviour: The Case of Energy Conservation

    Directory of Open Access Journals (Sweden)

    Octav-Ionuţ Macovei

    2015-08-01

    Full Text Available This paper aims to propose and validate a model based on the Theory of Planned Behavior in order to explain consumers’ pro-environmental behaviour regarding energy conservation. The model was constructed using the five variables from Ajzen’s Theory of Planned Behavior (TPB (behaviour, intention, perceived behavioural control, subjective norms and attitude to which a variable adapted from Schwartz’s Norm Activation Theory (NAT was added (“awareness of the consequences and the need” in order to create a unique model adapted for the special case of energy conservation behaviour. Further, a survey was conducted and the data collected were analysed using structural equation modelling. The first step of data analysis confirmed that all the constructs have good reliability, internal consistency and validity. The results of the structural equation analysis validated the proposed model, with all the model fit and quality indices having very good values. In the analysis of consumers’ proenvironmental behaviour regarding energy conservation and their intention to behave in a proenvironmental manner, this model proved to have a strong predictive power. Five of seven hypotheses were validated, the newly introduced variable proving to be a success. The proposed model is unique and will offer companies and organizations a valuable green marketing tool which can be used in the fight for environment protection and energy conservation.

  10. 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.

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

    International Nuclear Information System (INIS)

    Al-Ajlan, S.A.; Al-Ibrahim, A.M.; Abdulkhaleq, M.; Alghamdi, F.

    2006-01-01

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

    1982-03-01

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

    1991-01-01

    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

    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.

    Full Text Available Wireless sensor network (WSN, which has broad application prospects, consists of small nodes with sensing, computation, and communications capabilities. IPv6 is used over low power WPAN (wireless personal area network which is run by 6LoWPAN technology on the LoWPAN devices. In order to establish seamless connection of two heterogeneous networks, that is, WSN and IPv6 network, this paper proposes an improved energy conservation and interconnection scheme (ECIS based on the analysis of the current schemes. Detailed design of each functional component in the new scheme is proposed, and an expansion of the SSCS module in NS2 802.15.4 simulator is examined. Comprehensive experiments on the simulation platform show that the newly proposed scheme is advantageous over existing results.

  6. Early Site Permit Demonstration Program: Station design alternatives report

    International Nuclear Information System (INIS)

    1993-03-01

    This report provides the results of investigating the basis for including Station Design Alternatives (SDAs) in the regulatory guidance given for nuclear plant environmental reports (ERs), explains approaches or processes for evaluating SDAs at the early site permit (ESP) stage, and applies one of the processes to each of the ten systems or subsystems considered as SDAS. The key objective o this report s to demonstrate an adequate examination of alternatives can be performed without the extensive development f design data. The report discusses the Composite Suitability Approach and the Established Cutoff Approach in evaluating station design alternatives and selects one of these approaches to evaluate alternatives for each of the plant or station that were considered. Four types of ALWRs have been considered due to the availability of extensive plant data: System 80+, AP600, Advanced Boiling Reactor (ABWR), and Simplified Boiling Water Reactor (SBWR). This report demonstrates the feasibility of evaluating station design alternatives when reactor design detail has not been determined, quantitatively compares the potential ental impacts of alternatives, and focuses the ultimate selection of a alternative on cost and applicant-specific factors. The range of alternatives system is deliberately limited to a reasonable number to demonstrate the or to the three most commonly used at operating plants

    1993-07-01

    The Slick Rock uranium mill tailings sites are located near the small town of Slick Rock, in San Miguel County, Colorado. There are two designated UMTRA sites at Slick Rock, the Union Carbide (UC) site and the North Continent (NC) site. Both sites are adjacent to the Dolores River. The UC site is approximately 1 mile (mi) [2 kilometers (km)] downstream of the NC site. Contaminated materials cover an estimated 55 acres (ac) [22 hectares (ha)] at the UC site and 12 ac (4.9 ha) at the NC site. The sites contain former mill building concrete foundations, tailings piles, demolition debris, and areas contaminated by windblown and waterborne radioactive materials. The total estimated volume of contaminated materials is approximately 620, 000 cubic yards (yd 3 ) [470,000 cubic meters (m 3 )]. In addition to the contamination at the two processing site areas, four vicinity properties were contaminated. Contamination associated with the UC and NC sites has leached into groundwater

    2000-03-31

    For the purpose of the COP3 joint implementation, this paper describes the report of year 2000 version on feasibility study on energy conservation at Teheran Oil Refinery in Iran. The facilities as the object of the study include those for atmospheric pressure distillation for a capacity of 125,000 BD, vacuum distillation for a capacity of 48,000 BD, visbreaker with a capacity of 21,000 BD, naphtha hydrogenated desulfurization and naphtha reforming for a capacity of 168,000 BD, vacuum gas oil hydro-cracking for a capacity of 20,000 BD, hydrogen production of 32 MMSCFD, four 32,000 lb/h boilers, and other off-site equipment. Improvement measures include control of excessive air rate in heating furnaces, installation of air heaters and waste heat boilers to recover heat from the heating furnace stack gas, and increase in heat recovery from interim reflux. The period to recover the energy conservation investment would be about one year for the control of oxygen concentration in the stack gas, and three to five years for other main devices. The total investment amount is estimated to be 10 to 15 billion yen. Annual fuel saving would amount to 600 to 800 million yen. CO2 emission of 1.38 million tons before applying the measures will be reduced by 260,000 tons after the measures would have been applied, or 19% reduction. The country's own fund will be used for small scale modification, but financial and technological assistance from Japan is desired for medium to large scale modification. (NEDO)

  12. Methods for assessing mine site rehabilitation design for erosion impact

    International Nuclear Information System (INIS)

    Evans, K. G.

    2000-01-01

    Erosion of rehabilitated mines may result in landform instability, which in turn may result in exposure of encapsulated contaminants, elevated sediment delivery at catchment outlets, and subsequent degradation of downstream water quality. Rehabilitation design can be assessed using erosion and hydrology models calibrated to mine site conditions. Incision rates in containment structures can be quantified using 3-dimensional landform evolution simulation techniques. Sediment delivery at catchment outlets for various landform amelioration techniques can be predicted using process-based and empirical erosion-prediction models and sediment delivery ratios. The predicted sediment delivery can be used to estimate an average annual stream sediment load that can, in turn, be used to assess water quality impacts. Application of these techniques is demonstrated through a case study applied to a proposed rehabilitation design option for the Energy Resources of Australia Ltd (ERA) Ranger Mine in the Northern Territory of Australia.

    Rustad, Hilde

    1996-12-31

    This report sums up the work done on energy conservation in state-owned civil buildings in Norway in 1978 - 1995. Departmental funding was provided for such projects annually in 1978 - 1993, while in 1994 - 1995 energy conservation work consisted in completing running projects. The calculated energy saving amounts to 162 GWh per year. About 60% of the reduction in energy consumption is due to energy conservation measures that lower the energy consumption from oil-based heating. These measures represent an annual reduction of environmentally harmful emissions of 26240 ton carbon dioxide and 41 ton sulfur dioxide. In addition to specific energy conservation measures, much work went into arranging courses and on making consumers follow-up their energy consumption with respect to efficiency. The report is aimed at people and technical committees involved in energy conservation work. 16 figs., 2 tabs.

    1993-09-01

    A cost-benefit analysis is presented of the energy conservation programs of Hydro-Quebec for 1991 to 2010. Three possible scenarios are simulated. In the first scenario, Hydro-Quebec data are used without modification. In the second, the simulation is carried out in the absence of the Hydro-Quebec programs, and in the third, it is assumed that any economies achieved are only for the short term. A comparison between these simulations allows determination of results concerning the advantages and the costs which the programs introduce for the three groups comprising society: the consumer, the producer, and the government. The results of these comparisons show that the consumer, the producer, and the whole society gain benefits from the energy conservation programs, while the government loses. 13 refs., 13 figs., 14 tabs

  4. Finding of no significant impact for the State Energy Conservation Program

    International Nuclear Information System (INIS)

    1996-01-01

    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

    1987-05-01

    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.

    Taiwan lacks indigenous energy resources and imports 99% of its energy supply. This heavy energy-dependence represents a hidden threat for Taiwan's energy security and economic development. The most effective solution thus is to adopt an energy-conservation policy, similar to those successfully implemented in certain highly developed countries, such as the UK, the USA, Japan, and Germany. From the successful experiences of these countries, this study proposes a general mechanism of increasing energy efficiency by 2% annually, together with an executive master plan, followed by a scenario breakdown for energy-conserving policy in Taiwan. The feasibility of these proposals has been confirmed by the finding that their achievements in terms of energy saving and CO 2 emission reduction conform to the goals of the 'Taiwan National Energy Conference 2005'

    Highlights: ► We identify the keys for energy conversation across China’s 31 provinces × 65 sectors. ► The results are visualized in map and matrix tables, and easy for use. ► 39 Industrial sectors by province are classified into three categories for conservation. ► There is large energy wasting in the public management sector. ► There are both urban–rural gap and provincial inequality on electricity consumption. - Abstract: In March 2011, China’s central government set a new challenging target of reducing its energy intensity by 16% during 2011–2015, after it had achieved a reduction of 19.1% during 2006–2010. And this new target was assigned to provincial authorities in August 2011. However, China’s provincial energy-economic developments are unbalanced and different provinces have different key sectors for energy conservation. Most previous studies focused on provincial energy efficiency at the aggregate level, or the three-industry level (or one-digit level). However, whether for policy decision or academic research, it is necessary to further subdivide the sectors. In this paper, we use three indicators (Gini Coefficient, energy consumption share and energy intensity) to compare provincial energy conservation potentials at the two-digit sector level. To our knowledge, this paper is the first one to identify the keys for energy conversation across the 31 provinces × 65 sectors. And the results are shown in visualized maps and matrix tables to help identify the key province × sectors for energy conservation easier. This also helps the central and provincial governments to distinguish key sectors when they monitor the energy conservation progress

    2013-01-01

    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

    2001-03-01

    Feasibility study on energy conservation and environmental improvement was carried out with the aim of considering the realization of the CDM (clean development mechanism) project for reduction of global warming gas emissions and contributing to the environmental improvement and economic growth in Pakistan. In the study, projects on the following were studied: coke oven coal moisture control (CMC), sinter cooler waste heat recovery, blast furnace hot stove waste heat recovery, blast furnace pulverized coal injection (PCI), blast furnace top pressure recovery turbine (TRT), hot strip mill reheating furnace regenerative type burner, coke oven environmental improvement, and blast furnace cast house dust collection. As a result of the study, the implementation of the following three projects was regarded as promising in terms of energy conservation and economical effects: blast furnace pulverized coal injection, blast furnace top pressure recovery turbine and hot strip mill reheating furnace regenerative type burner. Further, the reduction in poisonous gas by the coke oven environmental improvement project was made a top priority. In Pakistan, the price of energy is kept low, and therefore, effects of energy conservation projects are not very much expected. However, the PCI project has an effect of substitution of low-priced domestic coal for imported coal. (NEDO)

  19. 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.

    2014-02-01

    Africa's response to climate change has largely been focused on adaptation rather than mitigation. The reason for this is based on the fact that the continent contributes very little to global CO2 emission. Again, mitigation policies like carbon tax as being practised in developed countries may be costly and difficult to implement in a continent where most economies are fragile. Using behavioural change as an adaptation approach, we examined the opinion of Ibadan city residents towards energy conservation and CO2 emissions reduction. A total of 822 respondents were sampled across the three residential neighbourhoods of the city. Results from the study showed that female and male respondents differed in their opinion towards energy conservation. However, the female respondents tended to record higher mean scores on majority of the items used to capture energy conservation behaviour than their male counterparts. Also, those with higher level of education seemed to be more conscious of the environmental consequences arising from energy use at home than those with lower educational background. However, very slight variations were recorded in the mean value score across the different age groups, those respondents above 50 years scored a bit higher than other age groups.

    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.

  4. An approach for evaluating utility-financed energy conservation programs. The economic welfare model

    Costello, K W; Galen, P S

    1985-09-01

    The main objective of this paper is to illustrate how the economic welfare model may be used to measure the economic efficiency effects of utility-financed energy conservation programs. The economic welfare model is the theoretical structure that was used in this paper to develop a cost/benefit test. This test defines the net benefit of a conservation program as the change in the sum of consumer and producer surplus. The authors advocate the operation of the proposed cost/benefit model as a screening tool to eliminate from more detailed review those programs where the expected net benefits are less than zero. The paper presents estimates of the net benefit derived from different specified cost/benefit models for four illustrative pilot programs. These models are representative of those which have been applied or are under review by utilities and public utility commissions. From the numerical results, it is shown that net benefit is greatly affected by the assumptions made about the nature of welfare gains to program participants. The main conclusion that emerges from the numerical results is that the selection of a cost/benefit model is a crucial element in evaluating utility-financed energy conservation programs. The paper also briefly addresses some of the major unresolved issues in utility-financed energy conservation programs. 2 figs., 3 tabs., 10 refs. (A.V.)

  5. Effects of energy conservation on equilibrium properties of hot asymmetric nuclear matter

    Zhang, Zhen; Ko, Che Ming

    2018-01-01

    Based on the relativistic Vlasov-Uehling-Uhlenbeck transport model, which includes relativistic scalar and vector potentials on baryons, we consider an N -Δ -π system in a box with periodic boundary conditions to study the effects of energy conservation in particle production and absorption processes on the equilibrium properties of the system. The density and temperature of the matter in the box are taken to be similar to the hot dense matter formed in heavy ion collisions at intermediate energies. We find that to maintain the equilibrium numbers of N ,Δ , and π , which depend on the mean-field potentials of N and Δ , we must include these potentials in the energy conservation condition that determines the momenta of outgoing particles after a scattering or decay process. We further find that the baryon scalar potentials mainly affect the Δ and pion equilibrium numbers, while the baryon vector potentials have considerable effect on the effective charged pion ratio at equilibrium. Our results thus indicate that it is essential to include in the transport model the effect of potentials in the energy conservation of a scattering or decay process, which is ignored in most transport models, for studying pion production in heavy ion collisions.

Last, the report provided several recommendations related to awareness and education; translation; incentives; delivery mechanisms; and pilot projects. The report concluded with an agreement to hold a provincial conference in Toronto on the issues raised in the report. The report concluded that an Aboriginal unit within the Bureau of Conservation of the Ontario Power Authority was envisioned to plan, develop, implement, manage and monitor the deliverables resulting from the report.

  8. China's experiment on the differential electricity pricing policy and the struggle for energy conservation

    International Nuclear Information System (INIS)

    Chen Jinjin

    2011-01-01

    Differential electricity pricing was promulgated by China's central government to guide the development of high energy-consuming industries, which are significant for energy conservation. This paper examines the twists and turns of the policy implementation at the provincial level, and seeks to elucidate the difficulties in its implementation. Local governments, concerned that following the central directives would hurt local interests, have tried to deviate from the central orders while the central revises the policy from time to time to ensure local compliance. Three difficulties are analyzed: (1) the current relations between the central and local energy regulatory institutions make these local institutions difficult to perform their duties, and affect incentives for local governments to respond to central directives; (2) financial reform puts a great burden on local governments to raise revenues to cover expenditures, making local governments focus mainly on economic development rather than serving merely as political agents of the central government; (3) the aggressive attitude of local governments in pursuing GDP growth is not necessarily driven by the central government, but by pressure from competition among localities and the need to win local support. Solving these difficulties is important for making national energy conservation polices effective and efficient. - Highlights: → Adopt the differential electricity pricing policy to achieve energy conservation. → The implementation of the differential electricity pricing policy is far from smooth. → Current relations between the central and local energy regulatory institutions. → Financial burden on local governments. → Pressure from competition among localities and the need to win local support.

    This paper describes the MultiAgency Radiation Survey and Site Investigation Manual (MARSSIM) strategy for designing a final status survey. The purpose of the final status survey is to demonstrate that release criteria established by the regulatory agency have been met. Survey design begins with identification of the contaminants and determination of whether the radionuclides of concern exist in background. The decommissioned site is segregated into Class 1, Class 2, and Class 3 areas, based on contamination potential, and each area is further divided into survey units. Appropriate reference areas for indoor and outdoor background measurements are selected. Survey instrumentation and techniques are selected in order to assure that the instrumentation is capable of detecting the contamination at the derived concentration guideline level (DCGL). Survey reference systems are established and the number of survey data points is determined-with the required number of data points distributed on a triangular grid Pattern. Two suitistical tests are used to evaluate data from final status surveys. For contaminants that are b, present in background, the Wilcoxon Rank Sum test is used; for contaminants that are not present in background, the Wilcoxon Signed Rank (or Sign) test is used. The number of data points needed to satisfy these nonparametric tests is based on the contaminant DCGL value, the expected Standard deviation of the contaminant in background and in the survey unit, and the acceptable probability of making Type I and Type II decision errors. The MARSSIM also requires a reasonable level of assurance that any small areas of elevated residual radioactivity that could be significant relative to regulatory limits are not missed during the final status survey. Measurements and sampling on a specified grid size are used to obtain an adequate assurance level that small locations of elevated radioactivity will Still satisfy DCGLs-applicable to small areas

    A study was undertaken to assess the merits of proposed design modifications to the Savannah River Site (SRS) reactors. The evaluation was based on the responses calculated by the RELAP5 systems code to double-ended guillotine break loss-of-coolant-accidents (DEGB LOCAs). The three concepts evaluated were (a) elevated plenum inlet piping with a guard vessel and clamshell enclosures, (b) closure of both rotovalves in the affected loop, and (c) closure of the pump suction valve in the affected loop. Each concept included a fast reactor shutdown (to 65% power in 100 ms) and a 2-s ac pump trip. System recovery potential was evaluated for break locations at the pump suction, the pump discharge, and the plenum inlet. The code version used was RELAP5/MOD2.5 version 3d3, a preliminary version of RELAP5/MOD3. The model was a three-dimensional representation of the K-Reactor water plenum and moderator tank. It included explicit representations of all six loops, which were based on the configuration of L-Reactor. A combination of features is recommended to ensure liquid inventory recovery for all break locations. Valve closure design performance for a break location in the short section of piping between the reactor concrete shield and the pump suction valve would benefit from the clamshell enclosing that section of piping. 7 refs., 10 figs., 2 tabs

  13. Design basis flood for nuclear power plants on river sites

    International Nuclear Information System (INIS)

    1983-01-01

    The Guide presents techniques for determining the design basis flood (DBF) to be used for siting nuclear power plants at or near non-tidal reaches of rivers and for protecting nuclear power plants against floods. Since flooding of a nuclear power plant can have repercussions on safety, the DBF is always chosen to have a very low probability of exceedance per annum. The DBF may result from one or more of the following causes: (1) Precipitation, snowmelt; (2) Failure of water control structures, either from seismic or hydrological causes or from faulty operation of these structures; (3) Channel obstruction such as landslide, ice effects, log or debris jams, and effects of vulcanism. Normally the DBF is not less than any recorded or historical flood occurrence. For flood evaluation two types of methods are discussed in this Guide: probabilistic and deterministic. Simple probabilistic methods to determine floods of such low exceedance probability have a great degree of uncertainty and are presented for use only during the site survey. However, the more sophisticated probabilistic methods, the so-called stochastic methods, may give an acceptable result, as outlined in this Guide. The preferred method of evaluating the component of the DBF due to precipitation, as described in this Guide, is the deterministic one, based on the concept of a limit to the probable maximum precipitation (PMP) and on the unit hydrograph technique. Dam failures may generate a flood substantially more severe than that due to precipitation. The methodology for evaluating these types of floods is therefore presented in this Guide. Making allowance for the possible simultaneous occurrence of two or more important flood-producing events is also discussed here. The Guide does not deal with floods caused by sabotage

    Science.gov (United States)

    Wegener, F. D. A.

    2009-11-01

    This thesis follows the career of the law of energy conservation in German science and culture between 1847 and 1914. There is an interesting contrast between the initial reception of Hermann Helmholtz’ 1847 treatise ‘Über die Erhaltung der Kraft’, which was rejected by the editor of the Annalen der Physik, and its later status as a classic of science. ‘Energy’ was the shared concept of the disciplines. It was used by physiologists, physicists, psychologists, sociologists and philosophers. Moreover, the law of energy conservation also made a huge cultural impact. The period around 1900 has justly been called an energetic era. Why did the law of energy conservation become such a universal success? The obvious way to explain this success would be to say: because it is true, and subsequently comment upon its great scientific value. This thesis adopts a different perspective. It adopts Wittgenstein’s definition of meaning as use in language. Consequently, the meaning of the law is only referred to in relation to the way in which it was put to use in communicative practice. From this perspective it is immediately evident that the understanding of the law of energy conservation was subject to considerable change. Helmholtz initially conceptualized the law in terms of atoms and forces; Gustav Kirchhoff and Ernst Mach, rejected atoms and forces as hypothetical entities and they preferred to use the more mundane concept of work instead; Wilhelm Ostwald, finally, thought of energy as an immaterial substance. This thesis meticulously follows the changes in use and understanding to which the law was subject as it penetrated German science and culture. Communication and interests, rather than natural essences, are the central explanatory concepts of the thesis. From 1847 onwards Helmholtz and Du Bois-Reymond actively sought to spread the law of energy conservation among their colleagues and the general public. They told their fellow physiologists, for example, that

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

    2012-01-01

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

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

    Energy Technology Data Exchange (ETDEWEB)

    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

    1981-01-01

    The hydrodynamic theory of surface wave propagation in semi-infinite homogeneous isotropic plasma is considered. Explicit linear surface wave solutions are given for the electric and magnetic fields, charge and current densities. These solutions are used to obtain the well-known dispersion relations and, together with the general energy conservation equation, to find appropriate definitions for the energy and the energy flow densities of surface waves. These densities are associated with the dispersion relation and the group velocity by formulae similar to those for bulk waves in infinite plasmas. Both cases of high-frequency (HF) and low-frequency (LF) surface waves are considered. (author)

    The capacity of Japan's commercial electric power facilities has been increased to more than 200 million kw. In order to provide a stable supply of electric power to meet constantly fluctuaring electric power demands, Japan's power plants generate electricity using an optimal combination of facilities, with nuclear power and coal-fired thermoelectric power providing the base load supply. In the use of electric power, moreover, measures are being implemented to reduce generation costs, conserve energy, and cut carbon dioxide emissions by reducing maximum output and equalizing the load. This report presents information concerning measures for improving the efficiency of electric power facilities operation, equalizing the load and promoting energy conservation. (author)

    Liberalisation of energy markets in Europe is in progress. The expressed goal is to promote efficiency through commercial competition, with lower energy prices for consumers as a consequence. This priority raises some complex questions in relation to the desire of creating a sustainable energy...... a sustainable energy development in efficiency and energy conservation. The electric utilities play an important role in this relation, but their priority is of commercial nature rather than concern for the environment. This dilemma is analyzed in more detail in the paper....

    Also in the area of rational use of energy and use of renewable energy sources modern computer systems gain more and more importance. More and more energy conservation specialists of consulting services, public administration and utility companies use for the preparation, realization and control of energy-saving measures electronic data processing. The aim is to be able to evaluate the partly very complex dependencies in energy consumption - e.g. between building heating, process control and illumination - in an acceptable period of time. A number of software houses has specialized in the development of programs for different partly very specific fields of application in the area of energy. (orig.)

    This paper posits that if consumer energy-conservation policy is to succeed in Canada, both behavioral and institutional obstacles must be identified and overcome. The behavioral barriers, identified through a national household survey, include consumer resistance to policies that affect their lifestyles. The institutional barriers obtained from a series of interviews with government officials, include weak federal-provincial relations. Viewed from a federal perspective, these obstacles are discussed and then linked to policy types. A prior understanding of the obstacles that a particular program type is likely to face should allow more-effective execution of the program and enhance the probability of success. 11 references, 7 tables.

    The Energy Study Centre, of the Dutch Energy Research Foundation and the Department of Social and Organisational Psychology, Leyden University have performed a researchproject on the effectiveness of behavior change-strategies to influence the energy use in households. An overview is presented of the different approaches to behavior change: information, the approach based on learning principles and the coercive-approach. A field experiment has been carried out in which the effects of four strategies were tested. These strategies were: 1. general information about how to conserve energy in the home, 2. weekly feedback with respect to the magnitude and financial consequences of the own energy-use, 3. weekly feedback with respect to the magnitude and financial consequences of the own energy-use compared with the use of people in comparable conditions (same houses), 4. weekly feedback (comparative) and financial incentives for reduction of energy-use. The results indicate that the individual feedback and financial incentives + feedback are effective in reducing energy-use, the comparative feedback is effective under certain conditions, the general information seems hardly effective. The results are also related to the attitudes of the residents towards energy conservation.

    1975-10-01

    This report addresses itself to the insights offered by the psychology of motivation to those wishing to encourage the conservation of energy. After an extensive review of the relevant literature, it was found that the bulk of the psychological literature offers little that can be adapted for immediate practical application to a large scale motivational campaign. There are, nevertheless, some well-supported conclusions that can be drawn from the theory and experimentation of psychology that are of direct relevance to the efficient and effective planning and execution of a campaign to encourage conservation of energy. This report addresses itself to these conclusions. The contents of the report include comments on the efficacy of various types of programs, the conditions under which those programs are most likely to succeed, and the critical elements which should be included in those programs if they are to exert their maximum effect. These types of programs include intrinsic and extrinsic motivation, i.e. creating new behavior patterns with internally or externally generated rewards, fear inducement (threats of energy shortages), and cogenitive dissonance, involving images of oneself and one's cultural environment. 66 refs.

    1980-03-01

    The likely environmental, social, and institutional impacts of selected energy-conservation measures in two communities in Washington state are reported. The five conservation measures investigated in this study were: (1) retrofitting existing buildings; (2) district heating and Integrated Community Energy Systems (ICES); (3) small automobiles and vehicle redesign; (4) land-use and housing modifications; and (5) electric-utility rate reform. Twenty potential impact areas were selected for analysis. These areas were divided into five categories of environmental impacts, economic impacts, community impacts, personal impacts, and overall quality of life in the community. The research was conducted in Seattle and Yakima, Washington. In each location, about two dozen public officials and business, labor, and community leaders were interviewed. Their diverse views are summarized. The Seattle respondents saw energy conservation as a highly desirable policy with a number of temporary, transitional problems arising as energy-conservation measures were implemented. Yakima respondents, in contrast, did not expect to encounter many serious energy problems in the foreseeable future and consequently viewed energy conservation as a relatively minor community concern. Moreover, they anticipated that many conservation measures, if implemented by the government, would encounter either apathy or resistance in their community. Two broad generalizations can bedrawn from these interviews: (1) energy conservation will basically be beneficial for the natural environment and our society; and (2) if energy conservation does become a dominant thrust in our society, it could stimulate and reinforce a much broader process of fundamental social change.

    The following themes were presented at this session: (1) the history and roles of the NEDO's introduction and promotion projects, (2) expectation and prospects to introduction and promotion of new energy and energy conservation technologies, (3) energy innovation in houses and buildings actively using new energies and energy conservation means, (4) works on introducing new energies by using the private finance initiative (PFI), and (5) the last resort for energy conservation promoting measures in the industrial domain (high-performance industrial furnace technologies). In Item 3, design cases intended for sustainable buildings were introduced. In Item 4, the PFI is explained as a means to use as much fund and management know-how in private sectors as possible in improving the social capitals and providing high-quality public services. In Japan, the PFI promotion law was established in July 1999 (the law concerning promotion of improvements in public facilities by utilizing funds in private sectors). Introductions are given on the wide area wastes disposal project in Kimitsu Area, the PFI model project for power generation of everyday use at Kanamachi Water Purification Plant of the Tokyo Metropolitan Water Supply Bureau, and the Omuta RDF power generation project. In Item 5, descriptions are given on a new high-performance industrial furnace using the combustion mechanism of 'high-temperature air combustion' created from preheated air at temperatures higher than spontaneous combustion temperature.

  18. Hydrogen, metals, bifurcating electrons, and proton gradients: the early evolution of biological energy conservation.

    Life is a persistent, self-specified set of far from equilibrium chemical reactions. In modern microbes, core carbon and energy metabolism are what keep cells alive. In very early chemical evolution, the forerunners of carbon and energy metabolism were the processes of generating reduced carbon compounds from CO(2) and the mechanisms of harnessing energy as compounds capable of doing some chemical work. The process of serpentinization at alkaline hydrothermal vents holds promise as a model for the origin of early reducing power, because Fe(2+) in the Earth's crust reduces water to H(2) and inorganic carbon to methane. The overall geochemical process of serpentinization is similar to the biochemical process of methanogenesis, and methanogenesis is similar to acetogenesis in that both physiologies allow energy conservation from the reduction of CO(2) with electrons from H(2). Electron bifurcation is a newly recognized cytosolic process that anaerobes use generate low potential electrons, it plays an important role in some forms of methanogenesis and, via speculation, possibly in acetogenesis. Electron bifurcation likely figures into the early evolution of biological energy conservation. Copyright © 2011. Published by Elsevier B.V.

  19. Impact of International Oil Price on Energy Conservation and Emission Reduction in China

    Full Text Available In the context of “new normal” economy and frequent “haze”, the strategy of energy conservation and emission reduction aiming to lower costs and reduce pollution is currently still a major strategic direction in China and the world, and will remain so for some time in the future. This paper uses the annual data of West Texas Intermediate (WTI crude oil price in 1987–2014 as samples. We firstly present the direction and mechanism of the influence of oil price change on total consumption of every kind of energy by path analysis, and then consider establishing a Structural Vector Autoregression model of energy conservation and emission reduction in three statuses. Research shows that if the international oil price increases by 1%, the energy consumption per GDP and carbon dioxide emission increase by 0.092% and 0.053% respectively in the corresponding period. In the status of high energy consumption and high emission, if the international oil price increases by 1%, the energy consumption per GDP and carbon dioxide emission increase by 0.043% and 0.065% respectively in the corresponding period. In the status of low energy consumption and low emission, if the international oil price increases by 1%, the energy consumption per GDP per unit increases by 0.067% and carbon dioxide emission decreases by 0.085% in the corresponding period.

    In this study, a Swedish house built in 1974, heated with resistance heaters was analysed. Different options for changing the heating system and electricity production were compared for this type of detached house, assuming coal-based electricity production as a reference. Changes in the fuel used, the electricity production technology, the end-use heating technology and the heat demand were analysed. The aim was to show how these different parts of the energy system interact and to evaluate the cost-effectiveness of reducing CO{sub 2} emission and primary energy use by different combinations of changes. The results showed that the CO{sub 2} emission and primary energy use could be reduced by 95 and 70%, respectively, without increased heating costs in a national economic perspective. The choice of end-use heating system had a greater influence than the energy conservation measures on the parameters studied. The energy conservation measures were less cost-effective in combination with the more energy-efficient heating systems, although the fact that they reduced the heat demand, and thus also the investment cost of the new heating system, was taken into account.

    Results of a study of the potential for energy conservation by producing chemicals from by-product or waste carbon monoxide (CO) from industrial sources are summarized. Extensive compilations of both industrial sources and uses for carbon monoxide were developed and included. Reviews of carbon monoxide purification and concentration technology and preliminary economic evaluations of carbon monoxide concentration, pipeline transportation and utilization of CO in the synthesis of ammonia and methanol are included. Preliminary technical and economic feasibility studies were made of producing ammonia and methanol from the by-product CO produced by a typical elemental phosphorus plant. Methanol synthesis appears to be more attractive than ammonia synthesis when using CO feedstock because of reduced water gas shift and carbon dioxide removal requirements. The economic studies indicate that methanol synthesis from CO appears to be competitive with conventional technology when the price of natural gas exceeds $0.82/million Btu, while ammonia synthesis from CO is probably not competitive until the price of natural gas exceeds $1.90/million Btu. It is concluded that there appears to be considerable potential for energy conservation in the chemical industry, by collecting CO rather than flaring it, and using it to make major chemicals such as ammonia and methanol.

    Alternative complexes III (ACIII) are recently identified membrane-bound enzymes that replace functionally the cytochrome bc(1/)b(6)f complexes. In general, ACIII are composed of four transmembrane proteins and three peripheral subunits that contain iron-sulfur centers and C-type hemes. ACIII are built by a combination of modules present in different enzyme families, namely the complex iron-sulfur molybdenum containing enzymes. In this article a historical perspective on the investigation of ACIII is presented, followed by an overview of the present knowledge on these enzymes. Electron transfer pathways within the protein are discussed taking into account possible different locations (cytoplasmatic or periplasmatic) of the iron-sulfur containing protein and their contribution to energy conservation. In this way several hypotheses for energy conservation modes are raised including linear and bifurcating electron transfer pathways.

    The study evaluates the energy saving potential of the Chinese steel industry by studying its potential future energy efficiency gap. In order to predict the future energy efficiency gap, a multivariate regression model combined with risk analysis is developed to estimate future energy intensity of China's steel industry. It is found that R and D intensity, energy saving investment, labor productivity and industry concentration are all important variables that affect energy intensity. We assess the possible measures as to how China's steel industry can narrow the energy efficiency gap with Japan by means of scenario analysis. Using Japan's current energy efficiency level as baseline, the energy saving potential of China's steel industry is more than 200 million ton coal equivalent in 2008, and it would fall to zero in 2020. However, if greater efforts were made to conserve energy, it would be possible to narrow down the energy efficiency gap between China and Japan by around 2015. Finally, using the results of the scenario analysis, future policy priorities for energy conservation in China's steel industry are assessed in this paper. - Highlights: → The energy saving potential of the Chinese steel industry is evaluated. → A multivariate regression model combined with risk analysis is developed. → R and D, energy saving investment, labor, and structure affect energy intensity.→ The energy saving potential of China's steel industry would fall to zero in 2020.→ Future policy for energy conservation in China's steel industry are assessed.

    An energy conservation plan was examined for Novo oil refinery of Bashneftechim Company in Ufa City, Bashkortstan, Russia for the purpose of making the plan tied to the COP3 joint implementation. The objective units in the study include an atmospheric and vacuum distillation unit with throughput of 7.8 million tons/year, a visbreaker and a vacuum gas oil hydrodesulfurization unit (for feedstock of FCC in Lenin Refinery), and a catalytic cracking unit, for example. Energy conservation measures are improvement and revamping of heating furnace to control excess air ratio in furnace, installation of air pre-heater or heat recovery boiler to recover heat from exhaust gas of heating furnace, additional installation of heat exchangers to recover heat from product oils, and efficiency improvement of overall operation by modernization of instrumentation and controlling equipment. The policy is not complete rebuilding of the facilities but utilizing the existing facilities by improving energy efficiency as far as possible. The study shows that investment for energy saving will be recovered within 3-6 years in many cases while total investment is estimated to be 1.5-3.0 billion yen. Total reduction of fuel consumption will be 500-800 million yen. Yearly reduction of CO2 emission will amount to 0.29 million tons (23%). (NEDO)

    Four state residential energy conservation programs are reviewed in terms of their origins, evolutions, purposes and goals, administration, organization, and outcomes. The four programs chosen were selected from among 30 nominated by state energy offices and regional Department of Energy personnel as being illustrative in terms of organization and/or outcomes. While intended primarily for state-level program managers and staff, the profiles of programs, conclusions, and recommendations should be useful to anyone interested in developing viable, action-oriented conservation programs. The four case studies included Oregon's Master Conserver program, Oklahoma's energy education project for low-income and elderly families, Virginia's workshops for heating dealers service and contractors, and Maine's three energy education projects - the Energy Bus, Energy Conservation Month, and the Home Energy Check-up. All four programs utilized Energy Extension Service (EES) funds from the federal government, and three were directly managed through the state EES organization. The findings of the study indicate that these programs (1) had flexibility to experiment, iterate, and reorganize as a result of their initial experiences, (2) made extensive use of networking to involve local groups in program delivery, (3) employed a large variety of delivery methods, and (4) made substantial efforts to tailor literature and handouts to the target audiences.

    The National Savings and Loan League (NSLL) has been researching techniques that may be used to finance energy-conservation measures in the residential sector. Twelve techniques developed and tested by NSLL are: future-advances clause under open-end mortgages; borrowing against existing savings accounts; home-improvement loans; variable-rate mortgages; second trusts or second mortgages; variable-payment mortgages; balloon-payment mortgages; deferred monthly payments for periods of excessive energy use; renegotiation of terms at set intervals; lower interest rates offered on mortgages in return for lender sharing in equity appreciation of the property; graduated payments; and deferred-interest loans. The testing took place in Pittsburgh, PA. The program consisted of 8 specific tasks, including several directed at different financial innovations for the financing of retrofits. Details are presented on findings; legal research; relationship of utilities to installation of retrofits; financing techniques applicable to retrofits; and national energy program for single-family residences. Some extensive attachments include information on: legal aspects, energy loan advertisements, and potential savings to be realized from various residential retrofit energy-conservation measures.

    For the purpose of reducing greenhouse effect gas emissions, a feasibility study was conducted on the energy conservation at Huta Sendzimir Steelworks in Poland. The study was made on quantity-energy consuming facilities such as blast furnace, sintering plant and steelmaking plant, power plant, by-producing gas, purchased power, etc. Moreover, as to the energy consuming system, surveys were made on the exhaust heat recovery equipment already introduced and energy saving equipment for pig iron/steel making. As a result, it was found out that Huta Sendzimir Steelworks has an ability and experiences for implementation of the energy conservation project with no problems. As methods to save energy in individual production process, the introduction of the following was proposed: pressure recovery turbine of blast furnace, equipment for high temperature stove exhaust heat recovery, sintering cooler exhaust heat recovery, oxygen combustion furnace exhaust gas recovery, etc. By the introduction of these equipment, the reduction amount of greenhouse effect gas emissions per year will be approximately 180,000 ton-CO2.

    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

    Households constitute an important target group when it comes to encouraging energy conservation. This dissertation provides an overview of the effectiveness of interventions aimed at encouraging households to reduce their energy use through behavioral changes. It also provides more insight into the factors related to household energy use and conservation. Tailored interventions in particular appear to be effective in reducing energy consumption. Households were given tailored information about energy saving measures they could apply. They were asked to try and save 5% energy and the website indicated how much energy they could save with each measure to attain that goal. Households also received feedback about their energy savings. Households who received the combination of tailored information, goal setting and tailored feedback via the Internet saved 5%, while households in a control group used more energy. Households had adopted more energy-saving measures and had more knowledge of energy conservation, compared to the control group. Also, household energy consumption appeared to be mainly related to socio-demographic variables, such as income and household size. Energy savings appeared to be mainly related to individual factors like perceived behavioral control. If the aim is to encourage households to adopt more sustainable lifestyles, it is important to provide them with more insight into which energy saving options are most effective for them to conserve energy. In view of the annual energy reduction targets set by the Dutch government, a tailor-made approach via the Internet can be an important step in that direction.

    We show that the nitrate storing vacuole of the sulfide-oxidizing bacterium Candidatus Allobeggiatoa halophila has an electron transport chain (ETC), which generates a proton motive force (PMF) used for cellular energy conservation. Immunostaining by antibodies showed that cytochrome c oxidase, an ETC protein and a vacuolar ATPase are present in the vacuolar membrane and cytochrome c in the vacuolar lumen. The effect of different inhibitors on the vacuolar pH was studied by pH imaging. Inhibition of vacuolar ATPases and pyrophosphatases resulted in a pH decrease in the vacuole, showing that the proton gradient over the vacuolar membrane is used for ATP and pyrophosphate generation. Blockage of the ETC decreased the vacuolar PMF, indicating that the proton gradient is build up by an ETC. Furthermore, addition of nitrate resulted in an increase of the vacuolar PMF. Inhibition of nitrate reduction, led to a decreased PMF. Nitric oxide was detected in vacuoles of cells exposed to nitrate showing that nitrite, the product of nitrate reduction, is reduced inside the vacuole. These findings show consistently that nitrate respiration contributes to the high proton concentration within the vacuole and the PMF over the vacuolar membrane is actively used for energy conservation. © 2012 Society for Applied Microbiology and Blackwell Publishing Ltd.

    For the purpose of reducing greenhouse effect gas emissions, the basic survey was conducted on potential energy conservation at Nanjing Refinery, Jiangsu Nanjing city, China. Investigational studies were made on the repair of the power recovery system in line with the plan to enlarge the fluid catalytic cracker (FCC) and the power recovery using exhaust gas from the RFCC catalytic regeneration system. Moreover, the energy conservation technology to reduce power loads of the refining system was adopted to this project. As a result, it was found out that this repair plan makes recovery of the power equivalent to 10.6MW possible and produces the effect of reducing the fuel to be used. The realization of this project brings the CO2 reduction amount of approximately 70,000 t/y. It was also found out that this project not only reduces a large amount of greenhouse effect gas emissions, but contributes to profits of the plant concerned and helps improve the environment in the area concerned. For the implementation of this project, the detailed plan is expected to be further discussed. (NEDO)

    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.

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

    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.

    The Weldon Spring Site Remedial Action Project is a remedial action effort funded by the U.S. Department of Energy. The Weldon Spring Site, a former uranium processing facility, is located in east-central Missouri on a portion of a former ordnance works facility which produced trinitrotoluene during World War II. As a result of both uranium and ordnance production, the soils have become both radiologically and chemically contaminated. As a part of site characterization efforts in support of the environmental documentation process, a chemical soil characterization program was developed. This program consisted of biased and unbiased sampling program which maximized areal coverage, provided a statistically sound data base and maintained cost effectiveness. This paper discusses how the general rationale and processes used at the Weldon Spring Site can be applied to other mixed and hazardous waste sites

    At present, energy consumption is to such an extent that if the same trend goes on then in the future at some point of time, the energy sources will all be exploited. Energy conservation in a hydraulic power pack refers to the reduction in the energy consumed by the power pack. Many experiments have been conducted to reduce the energy consumption and one of those methods is by introducing a variable frequency drive. The main objective of the present work is to reduce the energy consumed by the hydraulic power pack using variable frequency drive. Variable Frequency drive is used to vary the speed of the motor by receiving electrical signals from the pressure switch which acts as the feedback system. Using this concept, the speed of the motor can be varied between the specified limits. In the present work, a basic hydraulic power pack and a variable frequency drive based hydraulic power pack were designed and compared both of them with the results obtained. The comparison was based on the power consumed, rise in temperature, noise levels, and flow of oil through pressure relief valve, total oil flow during loading cycle. By comparing both the circuits, it is found that for the proposed system, consumption of power reduces by 78.4% and is as powerful as the present system.

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

  6. The Post-Intervention Persistence of Energy Conservation Behaviors: An Evaluation of the ‘Start Green’ Program

    Full Text Available For more than four decades, behavioral intervention programs informed by psychology have been employed to increase pro-environmental behaviors. However, there has been little evidence for the post-intervention durability of target behaviors. The few studies that have conducted such evaluations have found that improvements often return to baseline levels post-intervention. This study evaluated the durability of home energy conservation behaviors before, during, and after a community based multi-technique intervention program, and examined the relationship between behavioral durability and the perceived importance, convenience and family norms of each behavior, as well as generalized pro-conservation decision making. The results show increased frequency in target behaviors that remain elevated seven months post-intervention. While the reported generalization of pro-conservation decision-making consistently increased during the study, perceived importance, convenience, and family norms of target conservation behaviors were largely unaffected. In addition, the few significant alterations in these perceptions were found to be due to increases during the post-intervention period only, indicating that they are not necessary pre-requisites for durable behavior change. These results show that a well designed community based intervention can have direct impacts on target behaviors that persist beyond its termination.

  7. Hanford Site waste tank farm facilities design reconstitution program plan

    1994-01-01

    Throughout the commercial nuclear industry the lack of design reconstitution programs prior to the mid 1980's has resulted in inadequate documentation to support operating facilities configuration changes or safety evaluations. As a result, many utilities have completed or have ongoing design reconstitution programs and have discovered that without sufficient pre-planning their program can be potentially very expensive and may result in end-products inconsistent with the facility needs or expectations. A design reconstitution program plan is developed here for the Hanford waste tank farms facility as a consequence of the DOE Standard on operational configuration management. This design reconstitution plan provides for the recovery or regeneration of design requirements and basis, the compilation of Design Information Summaries, and a methodology to disposition items open for regeneration that were discovered during the development of Design Information Summaries. Implementation of this plan will culminate in an end-product of about 30 Design Information Summary documents. These documents will be developed to identify tank farms facility design requirements and design bases and thereby capture the technical baselines of the facility. This plan identifies the methodology necessary to systematically recover documents that are sources of design input information, and to evaluate and disposition open items or regeneration items discovered during the development of the Design Information Summaries or during the verification and validation processes. These development activities will be governed and implemented by three procedures and a guide that are to be developed as an outgrowth of this plan

    This report is the result of a geochemical investigation of the former uranium mill and tailings site at Durango, Colorado. This is one in a series of site specific geochemical investigations performed on the inactive uranium mill tailings included in the UMTRA Project. The objectives of the investigation are to characterize the geochemistry, to determine the contaminant distribution resulting from the former milling activities and tailings, and to infer chemical pathways and transport mechanisms from the contaminant distribution. The results will be used to model contaminant migration and to develop criteria for long-term containment media such as a cover system which is impermeable to contaminant migration. This report assumes a familiarity with the hydrologic conditions of the site and the geochemical concepts underlying the investigation. The results reported are based on a one-time sampling of waters and solid material from the background, the area adjacent to the site, and the site. The solid samples are water extracted remove easily soluble salts and acids extracted to remove cabonates and hydroxides. The water extracts and solid samples were analyzed for the major and trace elements. A limited number of samples were analyzed for radiological components. The report includes the methods of sampling, sample processing, analysis, and data interpretation. Three major conclusions are: (1) carbonate salts and low TDS characterize the tailings; (2) the adjacent area and raffinate ponds contain contaminants deposited by a single event of fluid permeation of the soils; and (3) the Animas River adjacent to the site has elevated gross alpha activity attributed to 226 Ra in the sediments derived from the tailings or milling activities

    In sensor network, energy conservation is one of the most critical issues since sensor nodes should perform a sensing task for a long time (e.g., lasting a few years) but the battery of them cannot be replaced in most practical situations. For this purpose, numerous energy conservation schemes have been proposed and duty cycling scheme is considered the most suitable power conservation technique, where sensor nodes alternate between states having different levels of power consumption. In order to analyze the energy consumption of energy conservation scheme based on duty cycling, it is essential to obtain the probability of each state. In this paper, we analytically derive steady state probability of sensor node states, i.e., sleep, listen, and active states, based on traffic characteristics and timer values, i.e., sleep timer, listen timer, and active timer. The effect of traffic characteristics and timer values on the steady state probability and energy consumption is analyzed in detail. Our work can provide sensor network operators guideline for selecting appropriate timer values for efficient energy conservation. The analytical methodology developed in this paper can be extended to other energy conservation schemes based on duty cycling with different sensor node states, without much difficulty.

    Corporate excessive energy consumption and emissions are negative externality problems, with the basic countermeasure of establishing a series of institutional programs to promote corporate energy conservation and emissions reduction. This paper analyzes the influence of institutional factors such as laws, tax policies, credit policies, government subsidies, media supervision and marketization degree on corporate energy conservation and emissions reduction from the institutional perspective. The data, from 84 listed Chinese chemical and steel companies from 2006 to 2010, was analyzed using both a fixed effect model and the generalized method of moments (GMM) model. The empirical results demonstrate that these institutional factors positively affect corporate energy conservation and emissions reduction. Specifically, four factors – tax policies, government subsidies, credit policies and media supervision – have a significant positive relationship with corporate energy conservation and emissions reduction; whereas laws and marketization degree exhibit no significant effects. The research findings are theoretically and practically significant to the Chinese government with regard to improving the institutional environment and promoting corporate energy conservation and emissions reduction. - Highlights: ► Theoretical analysis of the influence of institutional factors based on NIE. ► Empirical analysis of the influence of institutional factors on ECER by regression. ► Economic measures and public opinions have positive influence on ECER in China. ► Laws and the degree of marketization have weak influence on ECER in China

    All attempts to generalize the three-dimensional Lorenz model by selecting higher-order Fourier modes can be divided into three categories, namely: vertical, horizontal and vertical-horizontal mode truncations. The previous study showed that the first method allowed only construction of a nine-dimensional system when the selected modes were energy-conserving. The results presented in this paper demonstrate that a five-dimensional model is the lowest-order generalized Lorenz model that can be constructed by the second method and that its route to chaos is the same as that observed in the original Lorenz model. It is shown that the onset of chaos in both systems is determined by a number of modes that describe the vertical temperature difference in a convection roll. In addition, a simple rule that allows selecting modes that conserve energy for each method is derived

  13. Energy conservation in the primary aluminum and chlor-alkali industries

    Energy Technology Data Exchange (ETDEWEB)

    1980-10-01

    The primary aluminum and chlor-alkali industries together use nearly 13% of the electrical energy consumed by US industry. As part of its mission to promote energy conservation in basic US industries, the DOE surveys the present technological status of the major electrochemical industries and evaluates promising technological innovations that may lead to reduced energy requirements. This study provides technical and economic analyses in support of a government program of research and development in advanced electrolytic technology. This program is intended to supplement the development efforts directed toward energy savings by private industry. Sections II and III of this report cover aluminum and chlorine production processes only, since these two industries represent over 90% of the electrical energy requirements of all electrolytic industries in the United States. Section IV examines barriers to accelerated research and development by the electrolytic industries, and makes suggestions for government actions to overcome these barriers.

    A band-pass filtering scheme is proposed to mitigate spectral broadening and channel coupling in the Nonlinear Schr\\"odinger (NLS) fiber optic channel. The scheme is modeled by modifying the NLS Equation to include an attenuation profile with multiple brick-wall filters centered at different frequencies. It is shown that this brick-walls profile conserves the total in-band energy of the launch signal. Furthermore, energy fluctuations between the filtered channels are characterized, and conditions on the channel spacings are derived that ensure energy conservation in each channel. The maximum spectral efficiency of such a system is derived, and a constructive rule for achieving it using Sidon sequences is provided.

    In this article, we describe details of the data used in the research paper "Confidence bounds for energy conservation in electric motors: An economical solution using statistical techniques" [1]. The data presented in this paper is intended to show benefits of high efficiency electric motors over the standard efficiency motors of similar rating in the industrial sector of Pakistan. We explain how the data was collected and then processed by means of formulas to show cost effectiveness of energy efficient motors in terms of three important parameters: annual energy saving, cost saving and payback periods. This data can be further used to construct confidence bounds for the parameters using statistical techniques as described in [1].

    The Desert Renewable Energy Conservation Plan (DRECP), a major component of California's renewable energy planning efforts, is intended to provide effective protection and conservation of desert ecosystems, while allowing for the sensible development of renewable energy projects. This NASA mapping report was developed to support the DRECP and the Bureau of Land Management (BLM). We outline in this document remote sensing image processing methods to deliver new maps of biological soils crusts, sand dune movements, desert pavements, and sub-surface water sources across the DRECP area. We focused data processing first on the largely unmapped areas most likely to be used for energy developments, such as those within Renewable Energy Study Areas (RESA) and Solar Energy Zones (SEZs). We used imagery (multispectral and radar) mainly from the years 2009-2011.

    The purpose of this study was to combine the physical pretreatments of grinding, sieving, and magnetic-separation processes to reclaim iron-rich materials from the desulfurization slag, and to use the remainder for cement clinker production. The iron-rich materials can be separated out efficiently by grinding for 30 min and sieving with a 0.3 mm mesh. The non-magnetic fraction of the particles smaller than 0.3 mm was in the majority, and proved to be suitable for use as a cement raw material. The raw mixes prepared with a pretreated desulfurization slag had a relatively high reactivity, and the temperature at which alite forms was significantly reduced during the clinkerization process. The clinkers produced with 10% desulfurization slag had a high level of alite and good grindability. Generally, the improvements in clinkerization and clinker grindability are beneficial to energy conservation in cement manufacture. 2010 Elsevier Ltd. All rights reserved.

    For a demonstration project, the costs and benefits of insulating concrete block curing kilns to isolate the kiln thermal mass from the curing cycle are determined. Data were developed on service life of FOAMGLAS insulation, the effect of Johnson burners on the insulation and mounting, performance of an alternative insulation (a rapidly installed, spray-on polyurethane foam), and a simple incentive to promote implementation of industrial energy conservation concepts. Data are tabulated and compared for the FOAMGLAS and CPR 480 polyurethane insulations. Specific studies of insulation that was installed on inside surfaces of kilns to lock the kiln-mass out of the curing cycle are given for Blocklite plant in California, the Ameron pipe plant in California, and the Superlite plant in Phoenix, Arizona.
