Sample records for energy reform measures

  1. Reforming Romanian energy policy

    Perkins, S.

    1993-01-01

    Success in reforming energy sector depends on the implementation of the programme of economic reform agreed in February 1993. The difficulty of the negotiations between the International Monetary Fund and the Romanian government reflects the wider difficulties faced by the economy as a whole. They can be blamed in part on the legacy of uneconomic and inflexible industrial development and in part on opposition from interest groups which stand to lose from reform. Nonetheless, in spite of hesitant approach, the government does appear committed to the economic reform necessary to establish a market-oriented economy. But as the danger of a financial crisis engendered by the inadequately supported short-term borrowing of foreign exchange becomes urgent, the question is whether economic reform can be now implemented fast enough to protect economic enterprises and saving from a debt crisis. The scope for further delay in implementing the 1993 economic reform programme is fast disappearing. Procrastination should not be allowed to threaten the success of the reforms achieved in the energy and other sectors of the economy. 8 refs., 2 figs

  2. The Danish Energy Reform

    2001-01-01

    Since 1998 Denmark has been in a process of re-regulating its energy market introducing competition and incentive based economic regulation. The ''Danish model'' reflects specific Danish political priorities on energy, environment and the role of the energy consumers. The paper focuses on the electricity sector, tracing the reasons why Denmark re-regulates the way it does and what are the results. Denmark is a small country of 43000 2 kilometers and 5.3 million inhabitants. Denmark is a net-exporter of oil and gas produced in the North Sea. The hydro-resources are negligible. Renewable energy, however, covers 11 percent of gross energy consumption.(author)

  3. Does the Energy Sector Reform Call for Reform

    This paper discusses the course of the energy sector reforms in Europe so far, its objectives, achievements, issues, and dilemmas. In particular, long term and security aspects of energy supply of Europe are analyzed. In addition to the legislative changes regarding the open energy market regulation, and primarily the changes, concerning electricity and natural gas markets, the past period saw dynamic changes of institutional framework such as: increasing members of the European Union, increased number of countries aspiring to the EU (candidate countries and potential candidates), changes in other European countries out of which Russia is the most significant energy producer. The paper analyzes the issue of responsibility between state - regulator - system operator - trader - energy buyer. In Europe, it is more a complex question because the system of responsibility includes the institution of the European Union. Therefore, the relations between EU - state - regulator - system operator - trader - energy buyer are especially important. The paper looks in to the issue of energy company integrations, creation of energy mega-undertakings and their influence on further market development. The question of monopolies now appears in s new form. The conclusions suggest possible measures for institutional influence on energy market development, especially in the network energy systems, which may have a positive impact on system security and stability and markets development and their long term sustainability.(author)

  4. Energy market reform and greenhouse gas emission reductions

    The report reviews micro-economic reform in the energy market and measures the impact that energy market reform is expected to have on greenhouse gas outcomes. It indicates that reform in the electricity and gas industries is delivering what was promised, an efficient market with lower energy prices and, over the longer term, will deliver a gradually reducing rate of greenhouse gas emissions per unit of energy produced. It also recognises that energy market reform has removed some barriers to the entry of less greenhouse gas intense fuels. These trends will result in reduced greenhouse gas intensity in the supply of energy and significant reductions in the growth in greenhouse gas emissions compared to what may have been expected without the reforms

  5. Welfare implication of reforming energy consumption subsidies

    2016-01-01

    Reforming energy consumption subsidies, in particular for fossil fuels, has been frequently referred to as a quick-win policy to enhance environmental mitigation. In addition, the removal of such subsidies may release a sizeable portion of a country's national budget for use on more productive targets. One of the most recognized challenges of such reform is “selling” the new energy prices to citizens, particularly those with a more fragile purchasing power. Several empirical and technical studies have prescribed that the reform might be supported by a direct compensation mechanism in order to ensure feasibility. This is what was done during the recent energy subsidy reform in Iran. However, the compensation mechanism implemented in Iran's reform was successful at the beginning, but did not proceed as expected. This has raised questions about the feasibility and sustainability of the direct compensation mechanism, and even of the reform policy itself. In this paper, we consider a stylized model where direct compensation is the instrument proposed to restore consumers’ utility against increased energy prices. We find that, when prices of Other Goods are affected by the announced reform policy, the feasibility of a subsidy reform critically depends on the value of certain parameters: the initial subsidization rate, the share of energy in the consumers’ bundle, and the energy portion of price of Other Goods. - Highlights: • A model of energy subsidy reform with direct compensation is proposed. • Feasibility of the reform is related to three key parameters. • An illustrative example using data from the recent Iranian reform is discussed.

    Full Text Available Combined (steam and CO2 reforming is one of the methods to produce syngas for different applications. An energy requirement analysis of steam reforming to dry reforming with intermediate steps of steam reduction and equivalent CO2 addition to the feed fuel for syngas generation has been done to identify condition for optimum process operation. Thermodynamic equilibrium data for combined reforming was generated for temperature range of 400–1000°C at 1 bar pressure and combined oxidant (CO2 + H2O stream to propane (fuel ratio of 3, 6, and 9 by employing the Gibbs free energy minimization algorithm of HSC Chemistry software 5.1. Total energy requirement including preheating and reaction enthalpy calculations were done using the equilibrium product composition. Carbon and methane formation was significantly reduced in combined reforming than pure dry reforming, while the energy requirements were lower than pure steam reforming. Temperatures of minimum energy requirement were found in the data analysis of combined reforming which were optimum for the process.

    Erdogdu, Erkan

    2007-01-01

    The Republic of Turkey has initiated an ambitious reform program in the most important segments of her energy market; which requires privatization, liberalization as well as a radical restructuring of these industries. However, there is no consensus that the measures introduced are optimal. The present article attempts, first, to evaluate the regulatory framework created by the laws of 2001 in terms of economic efficiency considerations; and second, to determine what still needs to be done to improve the current situation. The paper not only provides an analysis of these reforms but also lists some policy suggestions. The study concludes that despite relatively good legislative framework, in practice, the reforms in Turkey are far from ideal as they are mainly in the form of 'textbook reforms'; and therefore a significant amount of work still lies ahead of Turkey to set up a fully fledged energy market

    Nuclear damage compensation and energy reform were closely related. Nuclear damage compensation cost should be part of generation cost of nuclear power. Extend of nuclear damage compensation was limited by compensation standard of Tokyo Electric Power Co. (TEPCO) following guidelines of Dispute Reconciliation Committee for Nuclear Damage Compensation. TEPCO had already paid compensation of about two trillion yen until now, which was only a part of total damage compensation cost. TEPCO had been provided more than 3.4 trillion yen by Nuclear Damage Liability Facilitation Cooperation, which would be put back by nuclear operators including TEPCO. TEPCO could obtain present raising funds and try to reconstruct business with restart of nuclear power, which might disturb energy reform. Present nuclear damage compensation scheme had better be reformed with learning more from Minamata disease case in Japan. (T. Tanaka)

    During the past ten years, the energy sector has passed through significant changes including fundamental market, economic, legislative and institutional aspects of sector operation. As the main goal of the Republic of Croatia is the integration into the European Union, the energy sector reform ought to be conducted in keeping with the present market development processes of the EU in such a way as to fulfil all safety criteria. In view of the above mentioned, the Croatian Parliament brought a number of laws during its session in July 2001 (''Official Gazette'' 68/01): 1. Energy Law 2. Energy Activities Regulation Law 3. Electricity Market Law 4. Gas Market Law 5. Oil and Oil Derivatives Market Law, which present the commencement of the energy sector reform (www.mingo.hr).(author)

    Cherni, Judith A.; Kentish, Joanna

    2007-01-01

    The article examines the potential effectiveness of the renewable energy policy in China and its regulatory Law framework. It frames the option of renewable energy technology within the background of the long-lasting electricity problems that China has faced including serious supply shortages, reliance on coal, and severe environmental contamination. Its dual administrative and ownership system based on state and privately owned industry is discussed together with the market reform measures adopted in the sector. Current renewable energy policy is analysed, and the scope of the 2005 Renewable Energy Promotion Law is investigated. This is conducted within the context of the electricity sector reform that China adopted, and its effects upon the prospects of encouraging as well as expanding the development of renewable energy. This study draws upon primary information collected from interviews with stakeholders on the policy adequacy, and identifies three main types of shortcomings that have interfered with a more successful expansion of renewable energy in China.

    Aruna, M.; Raj, M.G.

    2008-01-01

    The government of India cannot afford to fund the total investment needed for restructuring the country's electric power sector. As such, India's Electricity Act of 2003 encouraged private participation to implement the required measures for efficient and optimum use of energy resources available in India and to supply quality power at the best cost to consumers. This paper described the present status of India's power sector with respect to generation, transmission and distribution of electricity. India's economy is growing at a faster rate compared to many other developing countries. It is expected that in the next 6 to 7 years additional capacity of 84,000 MW will be needed to meet the projected electricity demand. The Power Finance Corporation Limited (PFC) was established in 1986 in order to generate and provide funds for the power sector, which is in the process of reforms in every element of the electricity value chain. India is facing an energy deficit and peak power deficit of 8 per cent and 12.2 per cent, respectively. The inter-regional power transmission capacity is planned to be increased from 16,500 MW to 37,000 MW by 2012. Thermal and nuclear energy are major sources for electricity production in India. As most of these resources are non renewable, they must be efficiently used. Coal will continue to contribute about 60 per cent of power generation in India. It was concluded that a large capacity national power grid is necessary for inter-regional power transfer, and that Transmission Super Highways are needed for the development of a high capacity National Power Grid. 7 refs., 1 tab., 3 figs

    There is little systematic information about the impact of energy sector reform on all sources and methods of energy utilised or potentially utilised by the poor. It is not sufficiently known what fuels the poor use, if a larger range of fuels becomes available and affordable and if barriers to access and consumption are reduced. A detailed assessment is presented for four countries, three in Africa (Botswana, Ghana and Senegal) and for comparison one in Latin America (Honduras), of steps taken to reform the energy sector and their effect on various groups of poor households. The paper analyses the pattern of energy supply to, and use by, poor households and explores the link-or its absence-to energy policy. We investigate what works for the poor and which type of reforms and implementation are effective and lead to a transition to more efficient and clean fuels from which the poor benefit. Energy sector reforms when adjusted to the specific conditions of the poor have a positive impact on access and use of clean, safe and efficient fuels. The poor are using gradually less wood as cooking fuel. Gas and kerosene are made more widely available through market liberalisation and subsidy in the particular case of Senegal. Electricity access and use is generally promoted or subsidised through changes in payment conditions and lifeline tariffs

    This paper is a subsequent study of China's energy security situation which concludes that China's energy security has not improved over 30 years of economic reform. The objective of the study is to explore qualitatively why the energy security situation has not improved. To answer the ‘why’ question, the study opens up a new perspective by analyzing the relationship between energy security and energy policies from the macroeconomic reform perspective. This study discusses major reforms that took place over 30 years. It is found that China's macroeconomic reform has restricted the formation of China's energy policies and determined its energy security situation. In essence, China's energy policies are only a reaction to the macroeconomic measures. In other words, China's energy policies are not originally intended to improve energy security, but passive reactions to China's macroeconomic reform. This explains why China did not improve its energy security situation despite 30 years of reform. - Highlights: • This study identifies relationship between China's reform and energy policy. • This study identifies the key variable that has affected China's energy security. • Policy implication of the identification is drawn. • A new perspective to analyze energy security is provided

    The new millennium brings change and new ways of thinking to the energy sector. Today the sector faces new challenges which it must deal with at a time where increasing market liberalisation and increasing internalisation is creating completely new frameworks for the sector. The Danish tradition of progressive energy policy action plans is the best possible basis on which to build. The target remains set. Energy policy must create the framework for structuring future energy systems so as to ensure that they are sustainable. Over many years there have been numerous initiatives to transfer consumption to cleaner energy sources, which has now led to a steady reduction in CO 2 emissions. The government places great importance on a continuation of this current development, both short term and long term. The adoption of the Electricity Reform in spring 1999 was an important step in the right direction. The government can, with great satisfaction, conclude that an agreement has now been made with most of the Parliament regarding a Gas reform, modernisation of the heat Supply Act and a new Energy Saving Act. In addition to this, the agreement also includes a follow up to the Electricity Reform concerning utilisation of biomass, offshore wind turbines, harmonisation of costs for priority electricity production, private generator's payment to priority electricity and the establishment of a market for electricity based on renewable.

    Among the renewable energies, wind energy has gained the rapidest development in China. Moreover wind power generation has been penetrated into power system in a large scale. However, the high level wind curtailment also indicates a low efficiency of wind energy utilization over the last decade in China. One of the primary constraints on the utilization of wind energy is the lack of an electricity market, in which renewable energies can compete equally with traditional fossil fuel generation. Thus the new round electric power industry reform is essential in China. The reform involves implementing new pricing mechanism, introducing retail-side competition, promoting the consumption of renewable energy. The new round reform can be a promising solution for promoting the development and consumption of wind energy generation in China. Based on proposed reform policies of electric power industry, this paper suggests a roadmap for retail electricity market reform of China, which consists of three stages. Barriers to the efficient utilization of wind energy are also analysed. Finally, this paper introduces several efficient measures for mitigating wind curtailment in each stage of reform.

  20. Energy Reforms in The Developing World: Sustainable Development Compromised?

    2015-06-01

    Full Text Available Energy sector reforms with an emphasis on electricity growth have been taking place extensively and rapidly worldwide Particularly, motivated chiefly by classical economics’ standpoint of efficiency and market considerations, reforms have been made in the developed North. Models of reforms in the North have in turn been replicated in developing countries. However, questions arise as to whether the models used are suitable for the mostly rural and socioeconomically disadvantaged economies in the South. It is argued in this paper that a sustainability focused mode of reforms guided by futures studies is needed for such economies. Reforms taking place in Kenya and neighbouring countries are in particular examined from a sustainable future perspective; and appropriate improvements and further research are recommended.

  1. Energy transition. Between reform and revolution

    International Nuclear Information System (INIS)

    Laville, Bettina

    2014-07-01

    The author comments the content of the French bill project on energy transition. She first discusses the meaning of this concept of energy transition which can be perceived as an evolution, a transformation, a progressive change, rather than a revolution. She recalls the original debate between those who wanted to preserve nuclear energy because it does not produce CO 2 emissions, and those who wanted a more radical change of the energy system. In this respect, she outlines and comments the main statements made by the French President on these issues, and indicates the main measures defined in the bill project regarding the reduction of greenhouse gas emission, the increase of the share of renewable energies, a decrease of the share of nuclear in power production, and a reduction of energy consumption. Then, she discusses how this transition is to be financed, proposes an assessment and a discussion of the skills and shortcomings of the bill project. She notably states that the main shortcoming is the lack of strong objectives regarding the reduction of emissions by transports, and the development of inter-modality. She also regrets the disappearance of the regional public service of energy efficiency, the fact that electricity consumption is not capped. Because of that, it's not that sure that the reduction of greenhouse gas emission by a factor 4 in 2050 with respect to 1990 will be reached. In the next parts, the author discusses the issue of the ecologic tax policy, outlines the importance of being exemplary within the perspective of the 2015 Conference on Climate (COP21)

  2. Energy reforms in central and eastern Europe - The first year

    International Nuclear Information System (INIS)

    1991-01-01

    The first stages of the energy reforms in central and eastern Europe - taking stock of the heritage of the past and conceptualizing the nature of reforms - were accomplished in 1990. While two countries - the USSR and Albania -introduced some market economy elements into central energy planning and basically maintained the latter, all other countries of central and eastern Europe opted for a replacement of central energy planning by market-oriented energy policies and practices. In those latter countries, a typical policy of market adaptation emerged consisting of a change of policies, institutions, economic instruments and relations. Differences in the conditions prevailing in the various countries resulted in the emergence of specific national ''models'' of market adaptation. The reforms, if successful, would imply: greater energy efficiency, reduced pollution, enhanced nuclear safety, a reduced impact on the climate, greater business opportunities, the closure of uneconomic capacities, a decline of coal production, a rise in unemployment; a rise of the energy trade dependence coupled with a rise of gas and oil imports; but practically no change of the net energy exports of the USSR. By the end of 1990 developed market economies agreed to co-ordinate assistance (within the ''Group of 24'') and determined the type and modalities of support. This support would enable and encourage the economies in transition to finalize reform, stimulate their practical implementation and address side effects (disinvestments, unemployment) and systematic risks (e.g. trade dependence) and opportunities (e.g. trade diversification). The business community and lending institutions would have to assess and support investments opportunities more actively. Intergovernmental organizations will play an important role in improving the conditions for business involvement. In 1990, the frameworks for energy reforms in central and eastern Europe, short term assistance, long term business

    This presentation will be based on the World Energy Council's recently published report, Energy Market Reform: Lessons Learned and Next Steps with Special Emphasis on the Energy Access Problems of Developing Countries. The report draws on practical lessons from past studies carried out by the World Energy Council and on current experiences on the desirable architecture of market reforms in electricity and natural gas. The approach of the study was not to further deepen the analysis or to provide technical recommendations but rather, to build a debate guided by the common thread of energy security and end-user e mpowerment , highlighting the possible areas of conflict of interest and the broad solutions that might be chosen depending on the local circumstances for different parts of the energy chains. The ambition was to identify key concerns and to initiate a debate on possible answers.(author)

    1992-01-01

    By the end of the winter 1991/92, the energy situation in central and eastern Europe had further deteriorated. Despite a significant fall in industrial demand, supply shortages occurred, pollution continued and safety problems remained potentially high. Top-down legislative and institutional reforms met with conflicting policies and structures. Energy trade declined and traditional trade patterns disintegrated. Western assistance had increased but had little impact on actual energy supplies, efficiency, pollution or safety as it was aimed at supporting structural reforms and securing a stable macro-economic famework. Also private sector investments while growing remained limited. Legislation on foreign investments, demonopolization and concessions, and energy policies were either still under debate or undergoing the first tests of their practicability and appeal. As 1992 unfolds the energy reform process appears at a critical stage. Its final success would seem to depend on a further special effort on the part of all concerned and on prioritisation. As the various initiatives depend on each other, their international co-ordination becomes a separate issue. 11 refs., 1 tab.

  6. The effects of the energy price reform on households consumption in Iran

    Moshiri, Saeed

    2015-01-01

    The substantial subsidizing of energy prices over the years has led to high energy consumption, inefficiencies, fiscal pressures, and environmental problems in Iran. To address the increasing socio-economic problems associated with the energy subsidies, the government embarked on an aggressive energy price reform through which energy subsidies were removed and cash handouts were given to all households in 2010. In this paper, I analyze the effectiveness of the energy price reform in Iran by estimating energy demand elasticities for households in different income groups. I apply a two-stage consumer optimization model and estimate the system of energy expenditures shares using the household budget survey data for the period 2001–2008. The results show that the overall price elasticities of demand are small, but income elasticities are close to one. The results also indicate heterogeneous responses to energy price and income changes in different income groups. Specifically, the urban households show stronger response to price changes, but rural households, particularly mid-income households, to income changes. These findings suggest that the current policy of price increases would not solely be able to reduce energy consumption and, therefore, it should be geared towards increasing energy efficiency through a series of price and non-price measures. - Highlights: • The effectiveness of the recent energy price reform in Iran is analyzed. • Energy demand elasticities for households in different income groups are estimated. • A two-stage optimization model was applied to estimate the system of equations using micro-data for 2001–2008. • The price elasticities are small and income elasticities rather large, but responses are heterogeneous. • A price and non-price reform policy package is needed for different income groups and regions

    Gabriele, Alberto

    2004-01-01

    This paper examines the policy alternatives faced by developing countries in their endeavor to preserve and develop their electricity and gas systems, two service-oriented industries which--along with oil--provide the bulk of energy supply both in developed and in developing countries. Even in very poor countries, industrially generated energy is indispensable for carrying out most economic activities. Therefore, governments traditionally recognize that the supply of gas and electricity entails a fundamental public service dimension. The Introduction presents the case for reforming of energy utilities, discusses in general terms the pros and cons of privatization, and attempts to locate the reforms in a broader historical framework in which developing countries' governments faced characterized by increasing financial hardship. Section 2 constitutes the core of the paper. It reviews the main features of gas and power sector reforms in the developing world and analyzes specifically the cases of five semi-industrialized countries in Latin America and Asia. Section 3 (Concluding remarks) briefly evaluates the country experiences reviewed above and indicates a few policy lessons which can be learnt from them. The main conclusion is that, in a long-run development perspective, full-scale privatization of gas and power sectors in developing countries entails significant risks, and therefore a flexible policy approach is preferable to a rigid commitment to extensive liberalization

    Highlights: • We measure fossil-fuel subsidies and effects of subsidy removal in a systematic fashion during 2006–2010. • Fossil-fuel subsidies scale of China was CNY 881.94 billion in 2010, equivalent to 2.59% of GDP. • Impacts of removing subsidies on macroeconomic variables are examined by the CGE model. • Future policy should focus on designing transparent, targeted and efficient energy subsidies. - Abstract: Fossil-fuel subsidies contribute to the extensive growth of energy demand and the related carbon dioxide emissions in China. However, the process of energy price reform is slow, even though China faces increasing problems of energy scarcity and environmental deterioration. This paper focuses on analyzing fossil fuel subsidies in China by estimating subsidies scale and the implications for future reform. We begin by measuring fossil-fuel subsidies and the effects of subsidy removal in a systematic fashion during 2006–2010 using a price-gap approach. Results indicate that the oil price reform in 2009 significantly reduced China’s fossil-fuel subsidies and modified the subsidy structure. Fossil-fuel subsidies scale in China was 881.94 billion CNY in 2010, which was lower than the amount in 2006, equivalent to 2.59% of the GDP. The macro-economic impacts of removing fossil-fuel subsidies are then evaluated by the computable general equilibrium (CGE) model. Results demonstrate that the economic growth and employment will be negatively affected as well as energy demand, carbon dioxide and sulfur dioxide emissions. Finally, policy implications are suggested: first, risks of government pricing of energy are far from negligible; second, an acceptable macroeconomic impact is a criterion for energy price reform in China; third, the future energy policy should focus on designing transparent, targeted and efficient energy subsidies

  10. Developing an energy efficient steam reforming process to produce hydrogen from sulfur-containing fuels

    Simson, Amanda

    Hydrogen powered fuel cells have the potential to produce electricity with higher efficiency and lower emissions than conventional combustion technology. In order to realize the benefits of a hydrogen fuel cell an efficient method to produce hydrogen is needed. Currently, over 90% of hydrogen is produced from the steam reforming of natural gas. However, for many applications including fuel cell vehicles, the use of a liquid fuel rather than natural gas is desirable. This work investigates the feasibility of producing hydrogen efficiently by steam reforming E85 (85% ethanol/15% gasoline), a commercially available sulfur-containing transportation fuel. A Rh-Pt/SiO2-ZrO2 catalyst has demonstrated good activity for the E85 steam reforming reaction. An industrial steam reforming process is often run less efficiently, with more water and at higher temperatures, in order to prevent catalyst deactivation. Therefore, it is desirable to develop a process that can operate without catalyst deactivation at more energy efficient conditions. In this study, the steam reforming of a sulfur-containing fuel (E85) was studied at near stoichiometric steam/carbon ratios and at 650C, conditions at which catalyst deactivation is normally measured. At these conditions the catalyst was found to be stable steam reforming a sulfur-free E85. However, the addition of low concentrations of sulfur significantly deactivated the catalyst. The presence of sulfur in the fuel caused catalyst deactivation by promoting ethylene which generates surface carbon species (coke) that mask catalytic sites. The amount of coke increased during time on stream and became increasingly graphitic. However, the deactivation due to both sulfur adsorption and coke formation was reversible with air treatment at 650°C. However, regenerations were found to reduce the catalyst life. Air regenerations produce exotherms on the catalyst surface that cause structural changes to the catalyst. During regenerations the

    Since the mid-nineties Brazil has implemented significant changes in the country's power sector, including privatization, introduction of competition and the creation of regulatory agency. As reform started in Brazil traditional support to energy efficiency and energy research and development suffered a discontinuation, budget cuts and re-definition of roles of the public agents in charge. At the same time, new regulatory measures and the creation of a national public interest fund have helped to maintain and potentially enhance the country's effort to promote energy efficiency and investments in energy R and D. This paper analyses the impacts of these changes in the areas of energy efficiency and energy research and development and argues for an increased role of developing countries to provide solutions for a meeting energy demand requirements more suitable to their internal markets

    By utilization of concentrated solar thermal energy for steam reforming of natural gas, which is an endothermic reaction, the chemical energy of natural gas can be up-graded. The chemical system for steam reforming of natural gas with concentrated solar thermal energy was studied to produce hydrogen by using the thermal storage with molten salt and the membrane reactor. The original steam reforming module with hydrogen permeable palladium membrane was developed and fabricated. Steam reforming of methane proceeded with the original module with palladium membrane below the decomposition temperature of molten salt (around 870 K). (authors)

    Fossil energy subsidies reform would be an effective way to improve the energy consumption structure; however, the reform needs to be assessed comprehensively beforehand as it would exert uncertain impacts on economy, society and environment. In this paper, we use price-gap approach to estimate the fossil energy subsidies of China, then establish CGE model that contains pollutant emissions accounts and CO 2 emissions account to stimulate the fossil energy subsidies reform under different scenarios, and the environmental economic analysis concept is introduced to monetize the pollutant reduction benefits. Furthermore, we analyze the possibility and scope of improving the energy consumption structure from the perspective of technical and economic analysis. Analytical results show that the energy consumption structure could be improved by different extent by removing coal or oil subsidies, while the economic and social indexes will be influenced distinctively. Meanwhile, the effects of cutting coal subsidies are more feasible than that of cutting oil subsidies overall. It is recommended to implement fossil energy subsidies gradually, cut the coal first and then cut oil subsidies successively. - Research highlights: → This paper estimates the scale of fossil energy subsidies of China in 2007 with price-gap approach. → We establish a Social Accounting Matrix and a CGE model extended with pollutant accounts. → We simulate the impacts of removing or cutting subsidies under three different scenarios. → We discuss the possibility and potential of improving energy consumption structure.

  14. Major energy users and reforms of the German energy industry

    1994-06-01

    There is a historic tradition of industrial autoproduction of electricity in Germany. Major energy users in the past used to be and today often still are autoproducers of electric power. The public utility sector, according to present legal standards, operates in a framework that protects local and regional monopolies. The large consumers and autoproducers are an important countervailing power in the whole system of the electricity supply industry. Electric utilities (EU) in Germany are semi-public or private enterprises of a wide variety of size. The large producer utilities operate the high voltage grid on the basis of private contracts. Regional distribution companies mostly without a considerable share in production often in cooperation with local distributors deliver electricity (el) in the non-urban areas whereas mostly city owned EU supply the large cities often on the basis of considerable parts of autoproduction and often also with a considerable share of el produced in cogeneration plants. The equilibrium between the parts of this system in the past was ensured by a legal framework protecting local monopolies as well as long term contracts between producers and distributors. Deregulation trends inherent in European legislation on competition have threatened this stability. In the first phase resistance against a more competitive order seemed unanimous. In the meantime however the different actors had time to rethink their position: The European Council has now proposed a more moderate regulation. The German Government has made a proposal for some important changes in the Energy Law and connected passages in the Competition Law, which would introduce some more competitive elements into the system without anticipating the results of a competitive process.

  16. Methodology and estimation of the welfare impact of energy reforms on households in Azerbaijan

    Science.gov (United States)

    Klytchnikova, Irina

    This dissertation develops a new approach that enables policy-makers to analyze welfare gains from improvements in the quality of infrastructure services in developing countries where data are limited and supply is subject to interruptions. An application of the proposed model in the former Soviet Republic of Azerbaijan demonstrates how this approach can be used in welfare assessment of energy sector reforms. The planned reforms in Azerbaijan include a set of measures that will result in a significant improvement in supply reliability, accompanied by a significant increase in the prices of energy services so that they reach the cost recovery level. Currently, households in rural areas receive electricity and gas for only a few hours a day because of a severe deterioration of the energy infrastructure following the collapse of the Soviet Union. The reforms that have recently been initiated will have far-reaching poverty and distributional consequences for the country as they result in an improvement in supply reliability and an increase in energy prices. The new model of intermittent supply developed in this dissertation is based on the household production function approach and draws on previous research in the energy reliability literature. Since modern energy sources (network gas and electricity) in Azerbaijan are cleaner and cheaper than the traditional fuels (fuel wood, etc.), households choose modern fuels whenever they are available. During outages, they rely on traditional fuels. Theoretical welfare measures are derived from a system of fuel demands that takes into account the intermittent availability of energy sources. The model is estimated with the data from the Azerbaijan Household Energy Survey, implemented by the World Bank in December 2003/January 2004. This survey includes an innovative contingent behavior module in which the respondents were asked about their energy consumption patterns in specified reform scenarios. Estimation results strongly

    The fuel processor in which hydrogen is produced from fuels is an important unit in a fuel cell system. The aim of this study is to apply a thermodynamic concept to identify a suitable reforming process for an ethanol-fueled solid oxide fuel cell (SOFC). Three different reforming technologies, i.e., steam reforming, partial oxidation and autothermal reforming, are considered. The first and second laws of thermodynamics are employed to determine an energy demand and to describe how efficiently the energy is supplied to the reforming process. Effect of key operating parameters on the distribution of reforming products, such as H2, CO, CO2 and CH4, and the possibility of carbon formation in different ethanol reformings are examined as a function of steam-to-ethanol ratio, oxygen-to-ethanol ratio and temperatures at atmospheric pressure. Energy and exergy analysis are performed to identify the best ethanol reforming process for SOFC applications. Copyright © 2014 Elsevier Ltd. All rights reserved.

    In the new millennium, understanding China's energy economy is crucial for politicians, businesspeople and energy economists, as China's energy policy choices will mean both challenges and opportunities for the world in terms of an increasing share of primary energy consumption and investment. This book initially reviews the literature on China's energy economy and in so doing reveals that many important areas have been overlooked or are outdated in their coverage. Given the size of China and its global importance, the book then review s China's current energy situation and fills the gaps in the literature for those who are interested in and concerned about China's economic development and energy reform in the new millennium. The book is different from previous studies in several important ways: Firstly, it presents recent, pioneering research rather than a simple textbook, several sections of which have been published in high-quality energy journals. Secondly, the book first subdivides China's energy intensity change into aspects of budget constraint, technological change, factor substitution, energy demand and economic growth using a newly developed econometric approach. Thirdly, it provides many new and different econometric findings and derives many new policy implications for China's energy economy. And lastly, it brings to light a wealth of new knowledge for those who are interested in China's energy economy, the world energy market and global environmental and climate change issues.

    This article presents an electrical energy sector reform 'initiative' adapted to developing countries, in particular those of Maghreb, in order to promote competitive electricity business outside of market structures. It is a matter 1) of authorizing access to networks and international interconnections for all high or low voltage consumers, in particular those very sensitive to electricity prices and to competition, in order to get electricity supply on foreign markets and/or from private producers and/or develop their own productions directly or via consortium; 2) of authorizing access to networks and international interconnections for every independent production destined for internal and/or foreign markets, resulting especially in the development of competitive supplies which are renewable or reduce network constraints; 3) of initiating (or promoting) the integrated management of supply, demand and network systems, around the fundamental principles of technical and economical optimizations, bearing in mind the sector's unique character in order to develop the trans-border electricity business. Much appreciated by internal and external economic operators, the outcome of this initiative applied to the development of self generation and launched for the first time in Morocco, is impressive, since less than one year following its launch, several national and foreign company associations committed, by way of signed agreements, to equip around a dozen wind energy sites spread across the whole of the land and totaling a power of more than 1000 MW so 20% to 25% of the country's current peak demand. Some of the region's countries have shown their keen interest in this solution. In addition, analysis and simulation studies carried out on the integrated systems of Maghreb and the Iberian Peninsula show that access to international networks and interconnections in order to choose one's own suppliers, means among other things that significant gains on production costs of

    From the point of view of the industry there are two central tasks for energy policy: 1. The German industry has to be supplied with energy at internationally competitive prices. Of the three aims of energy policies (secure, moderately-priced and low-pollutant) the price aim is in Germany in the international comparison today least achieved. 2. Policy always tends to solve problems in the energy sector with regulating interventions. An example from the recent past is the power supply law of 1990 with which the way to political electricity pricing was opened. But the precept for the Internal European Market has to be deregulation as only in this way the larger market can develop its efficiency to the full. Also for the reform of the economic laws concerning the energy sector these two central aims have to be taken into consideration. (orig./UA).

  2. Measuring industrial energy savings

    2008-01-01

    Accurate measurement of energy savings from industrial energy efficiency projects can reduce uncertainty about the efficacy of the projects, guide the selection of future projects, improve future estimates of expected savings, promote financing of energy efficiency projects through shared-savings agreements, and improve utilization of capital resources. Many efforts to measure industrial energy savings, or simply track progress toward efficiency goals, have had difficulty incorporating changing weather and production, which are frequently major drivers of plant energy use. This paper presents a general method for measuring plant-wide industrial energy savings that takes into account changing weather and production between the pre and post-retrofit periods. In addition, the method can disaggregate savings into components, which provides additional resolution for understanding the effectiveness of individual projects when several projects are implemented together. The method uses multivariable piece-wise regression models to characterize baseline energy use, and disaggregates savings by taking the total derivative of the energy use equation. Although the method incorporates search techniques, multi-variable least-squares regression and calculus, it is easily implemented using data analysis software, and can use readily available temperature, production and utility billing data. This is important, since more complicated methods may be too complex for widespread use. The method is demonstrated using case studies of actual energy assessments. The case studies demonstrate the importance of adjusting for weather and production between the pre- and post-retrofit periods, how plant-wide savings can be disaggregated to evaluate the effectiveness of individual retrofits, how the method can identify the time-dependence of savings, and limitations of engineering models when used to estimate future savings

    It has been demonstrated that if the renewable energies are stopped the problems will grow and that with more renewable the price of energy is reduced. An effective energy reform should begin by recognizing the impacts of the crisis on the electric power system in order to decide on profound changes in the energy mix, the regulated costs and the setting of electricity prices, to make energy saving a top priority and to promote more competitive, consumer-friendly energy markets.

    Highlights: • The effect of O_2 content from 0 to 15% on Ni/SiO_2 are studied for biogas reforming. • The presence of O_2 in biogas improves CH_4 conversion and stability of biogas reforming. • An obvious carbon-resistance effect is observed due to the carbon gasification effect of O_2 in biogas. • The presence of O_2 in biogas greatly helps inhibit the catalyst sintering. - Abstract: We report an energy-efficient biogas reforming process with high and stable methane conversions by O_2 presence. During this biogas reforming process, the effects of various O_2 concentrations in biogas on initial conversions and stability at various temperatures on a Ni/SiO_2 catalyst were detailed investigated. In addition, theoretical energy consumption and conversions were calculated based on the Gibbs energy minimization method to compare with experimental results. Carbon formation and sintering during the reforming process were characterized by thermal gravity analysis, the Brunauer-Emmett-Teller method, X-ray diffraction, and high-resolution transmission electron microscopy to investigate the feasibility of applying this process to an inexpensive nickel catalyst. The results showed that 5% O_2 in biogas improved the CH_4 conversion and stability of biogas reforming. The enhancement of stability was attributed to the inhibited sintering, our first finding, and the reduced carbon deposition at the same time, which sustained a stable conversion of CH_4, and proved the applicability of base Ni catalyst to this process. Higher O_2 concentrations (⩾10%) in biogas resulted in severe decrease in CO_2 conversion and greater H_2O productivity. Our proposed biogas reforming process, with a high and stable conversion of CH_4, reduced energy input, and the applicability to inexpensive base metal catalyst, offers a good choice for biogas reforming with low O_2 concentrations (⩽5%) to produce syngas with high energy efficiency.

    2014-01-01

    The aim of this study is to analyze the effect that the Energy Tax Directive reform proposed in 2011 would have, if implemented, on the level of prices in the different sectors of the 27 countries of the European Union. We apply a multiregional and multisectoral model of trade flows that takes into account all the intersectoral and intercountry interdependences in the production processes. Using the World Input–Output Database we perform two different simulations. The first one considers the tax changes proposed by the reform; the second one shows the impact the reform would have entailed if it were applied also to sectors belonging to the European Trade System. The main finding of the first simulation shows that the new energy tax regime would have had a low economic cost in terms of impact on prices (less than 1% in all the countries). So, the concerns about competitiveness do not find empirical support in our results, suggesting the need for further analyses to find out the reasons that caused the failure of a reform that was an important step to introduce a taxation explicitly linked to CO 2 emissions. The second simulation, however, leads to strongly different results, pointing out the relevance of maintaining significant economic incentives to reduce carbon emissions for the European Trade System sectors, by improving the emission market performance or by applying carbon taxation also to these sectors. - Highlights: • We analyze the reform of the European energy tax proposed in 2011, rejected in 2012. • We simulate what potential economic effect this reform would have if implemented. • We find that this reform would have weak effects on prices in all 27 EU countries. • We study the effect of the reform if applied to European emission market sectors. • In this second scenario, the economic impacts would have been much stronger

    Full Text Available The article attempts to revise the issue of the State regulation of the macroeconomic processes associated with the economic, energy, fiscal, and educational reforms that are being carried out in Ukraine. In order to implement the State energy policy, fiscal approaches have been emphasized. The use of the fiscal stimulus of «carbon tax» can be seen as an effective measure for implementation of the existing State energy strategy. A review of introduction of such a tax in the developed countries confirms the expediency of applying fiscal mechanism in order to encourage investment in energy-efficient technologies. Prospects for introduction of this tax in Ukraine were considered. To this end, actual CO2 emissions have been generalized and prediction calculations for the energy sector have been accomplished. The calculated estimates of possible tax revenues have been provided. For further studies on the outlined topic, there is an impelling need to detalize the financial statistics of the ecologic tax revenues in terms of sources.

    Highlights: • Energy storage of methane reforming in a tubular packed reactor is investigated. • Thermochemical storage efficiency approaches maximum at optimal temperature. • Sensible heat and heat loss play important roles in the energy storage system. • The reaction and energy storage models of methane reforming reactor are established. • The simulated methane conversion and energy storage efficiency fit with experiments. - Abstract: High temperature heat transfer and energy storage performances of methane reforming with carbon dioxide in tubular packed reactor are investigated under different operating conditions. Experimental results show that the methane reforming in tubular packed reactor can efficiently store high temperature thermal energy, and the sensible heat and heat loss besides thermochemical energy storage play important role in the total energy storage process. When the operating temperature is increased, the thermochemical storage efficiency first increases for methane conversion rising and then decreases for heat loss rising. As the operating temperate is 800 °C, the methane conversion is 79.6%, and the thermochemical storage efficiency and total energy efficiency can be higher than 47% and 70%. According to the experimental system, the flow and reaction model of methane reforming is established using the laminar finite-rate model and Arrhenius expression, and the simulated methane conversion and energy storage efficiency fit with experimental data. Along the flow direction, the fluid temperature in the catalyst bed first decreases because of the endothermic reaction and then increases for the heat transfer from reactor wall. As a conclusion, the maximum thermochemical storage efficiency will be obtained under optimal operating temperature and optimal flow rate, and the total energy efficiency can be increased by the increase of bed conductivity and decrease of heat loss coefficient.

  10. What lessons have been learned in reforming the Renewables Obligation? An analysis of internal and external failures in UK renewable energy policy

    Wood, Geoffrey; Dow, Stephen

    2011-01-01

    Despite operating a delivery programme for RES-E since 1990, UK targets and policy goals have not been achieved. In response, the Government reformed the RO. This article re-examines UK renewable energy policy by analysing the internal and external failures of the various mechanisms to determine if Government has learnt from previous experience in reforming the RO. Government did not learn from their own actions during the NFFO/RO transition, evidenced by high-levels of similarity in internal/external failures. The reformed-RO is expected to significantly increase deployment, has provided a 'renewables package' by comprehensively addressing both internal/external failures but major internal failures (price/financial risk) still remain, resulting in contiguous failures over two decades and two mechanism changes (NFFO, RO, RO/reformed-RO). Success will again be heavily dependent on a select few technologies and new/untested measures to combat external failures. Mechanism-extension to 2037 is probably the single most important factor underlying potential deployment increases. However, introducing a FIT-like system via the sheer number of 'bolt-on' reforms to counter policy failures indicates loss of direction and clarity. Overall, although Government appears to have learnt some of its lessons from the past two-decades, significant doubt remains whether renewable energy policy objectives will be met via the latest mechanism change. - Research highlights: → Review of UK renewable energy policy learning behaviour via the 2009 Renewable Obligation reform. → Applies key lessons and analysis of NFFO/RO, RO reform and possible FIT schemes. → Finds UK Government has learnt some lessons from the past but some failures remain contiguous over two decades. → In contrast to previous changes, 2009 reform provided a comprehensive reform package. → Significant doubt remains whether objectives will be met via latest mechanism change.

    1981-01-01

    High-frequency (> 100 MHz) energy measurements present special problems to the experimenter. Environment or available electronics often limit the applicability of a given detector type. The physical properties of many detectors are frequency dependent and in some cases, the physical effect employed can be frequency dependent. State-of-the-art measurements generally involve a detection scheme in association with high-speed electronics and a method of data recording. Events can be single or repetitive shot requiring real time, sampling, or digitizing data recording. Potential modification of the pulse by the detector and the associated electronics should not be overlooked. This presentation will review typical applications, methods of choosing a detector, and high-speed detectors. Special considerations and limitations of some applications and devices will be described

  15. Can market oriented economic reforms contribute to energy efficiency improvement? Evidence from China

    International Nuclear Information System (INIS)

    Fan Ying; Liao Hua; Wei Yiming

    2007-01-01

    Since China accelerated its market oriented economic reforms at the end of 1992, its energy intensity has declined 3.6% annually over 1993-2005. However, its energy intensity declined 4.2% annually during its first reform period 1979-1992. Therefore, can we conclude that the accelerated marketization since the end of 1992 has made no contribution to its energy efficiency improvement? In order to answer this challenging question, we examine the changes of energy own-price elasticity, as well as the elasticities of substitution between energy and non-energy (capital and labor) in China during the periods of 1979-1992 and 1993-2003. Generally, in transition or developing economies, holding the technology and output level fixed, if the energy own-price elasticity (algebraic value) declines or the substitution elasticity between factors rises, they will contribute to energy efficiency improvement. Our empirical study finds that: (1) during 1979-1992, the energy own-price elasticity is positive (0.285), and capital-energy, labor-energy are both Morishima complementary; which indicates a distorted energy price and inefficient allocation; and (2) during 1993-2003, the own-price elasticity for energy is negative (-1.236), and capital-energy and labor-energy are both Morishima substitute. All factor demands become more elastic, and all elasticities of substitution increase.

    2015-01-01

    This article discusses the concept of a direct-injection ICE (internal combustion engine) with thermo-chemical recuperation realized through SRM (steam reforming of methanol). It is shown that the energy required to compress the reformate gas prior to its injection into the cylinder is substantial and has to be accounted for. Results of the analysis prove that the method of reformate direct-injection is unviable when the reforming is carried-out under atmospheric pressure. To reduce the energy penalty resulted from the gas compression, it is suggested to implement a high-pressure reforming process. Effects of the injection timing and the injector's flow area on the ICE-SRM system's fuel conversion efficiency are studied. The significance of cooling the reforming products prior to their injection into the engine-cylinder is demonstrated. We show that a direct-injection ICE with high-pressure SRM is feasible and provides a potential for significant efficiency improvement. Development of injectors with greater flow area shall contribute to further efficiency improvements. - Highlights: • Energy needed to compress the reformate is substantial and has to be accounted for. • Reformate direct-injection is unviable if reforming is done at atmospheric pressure. • Direct-injection engine with high-pressure methanol reforming is feasible. • Efficiency improvement by 12–14% compared with a gasoline-fed engine was shown

    The Western Balkans - composed of Albania, Bosnia and Herzegovina, Croatia, the Former Yugoslav Republic of Macedonia, Montenegro, Serbia and Kosovo - is a complex region facing significant energy challenges. The conflicts over the break-up of the former Yugoslavia damaged much of the energy infrastructure and compounded the challenge of providing reliable energy supply. Electricity systems in many parts of the region remain fragile and in need of investment. A priority across the region is to put into place the institutions, infrastructure and policies that can support the provision of reliable, affordable and sustainable energy. For the Western Balkans as a whole, a key element of the reform effort is the Energy Community Treaty - a regulatory and market framework to which the entire region has now subscribed. This Treaty aims to create an integrated regional market for electricity and gas compatible with the European Union's internal energy market. This Energy Policy Survey is the first comprehensive review of energy policies and strategies in the Western Balkan region, and also covers important cross-cutting topics such as co-operation and energy trade, oil and gas transportation, and the links between energy and poverty. It identifies and assesses the reforms that are still needed to deliver efficient, modernised energy systems that can assist economic development, address energy poverty and reduce the environmental impacts of energy use.

    Given increasing concern over global climate change and national security there is a burgeoning interest in examining the relationship between economic growth and energy use in developed and developing countries. More specifically, decoupling energy use per unit of gross domestic product (GDP) has fast come to be seen as in the interests of national economies and the world as a whole. Recent attention has been paid to the dramatic decreases in the energy intensity of the Chinese economy, which fell by 55% between 1975 and 1995. Do other developing economies follow similar trajectories? This paper examines the energy intensity of the Mexican economy for the period 1988-1998. Although the long-term trend in Mexican energy intensity is rising, the energy intensity of the Mexican economy began to decline in 1988. This paper explores the factors that have contributed to this reduction. Diminishing Mexican energy use per unit of GDP has been driven by significant decreases in industrial energy intensity. We show that these changes have resulted from changes in the composition of Mexican industrial structure, and technological change

    Highlights: •A novel CCHP system with biogas steam reforming using solar energy is raised. •Chemical and physical energy of biogas is efficiently used in a cascaded way. •The energy quality of concentrating solar heat is promoted in the system. •A parametric analysis is adopted to optimize the thermodynamic performance. •A typical-day study is conducted to explore the general operation features. -- Abstract: The conventional way to utilize biogas either is energy-intensive due to biogas upgrading or causes huge waste of energy grade and environmental pollution by direct burning. This paper proposes a biogas and solar energy-assisted combined cooling, heating and power (BSCCHP) system that upgrades the caloric value of biogas before combustion by introducing a thermochemical conversion process that is driven by solar heat. Adopting commercially established technologies including steam reforming and parabolic dish concentrators, the system exhibits an enhanced system exergy efficiency, and the technology considerably reduces the direct CO 2 footprint and saves depletable fossil fuel. With a solar thermal share of 22.2%, the proposed system not only has a high net solar-to-product thermal and exergy efficiency of 46.80% and 26.49%, respectively, but also results in a commensurate 18.27% reduction of the direct CO 2 footprint compared with the reference individual systems. The effect of critical parameters in the biogas steam reforming process on the system performance was studied. A proper selection of the steam/carbon ratio leads to the optimal direct CO 2 footprint and system exergy efficiency. Pursuing a very high conversion of biogas by improving the reforming temperature is not a wise choice from a system perspective. Finally, a typical-day dynamic simulation was conducted to preliminarily explore the general operation features. This study may provide a new way to efficiently use the renewable energy in the distributed energy system.

    Improving energy efficiency is the primary method adopted by the Chinese government in an effort to achieve energy conservation target in the transport sector. However, the offsetting effect of energy rebound would greatly reduce its real energy-saving potentials. We set up a Linear Approximation of the Almost Ideal Demand System Model (LA-AIDS model) to estimate the rebound effect for passenger transportation in China. Real energy conservation effect of improving energy efficiency can also be obtained in the process. The result shows that the rebound effect is approximately 107.2%. This figure signifies the existence of ‘backfire effect’, indicating that efficiency improvement in practice does not always lead to energy-saving. We conclude that one important factor leading to the rebound effect, is the refined oil pricing mechanism. China's refined oil pricing mechanism has been subjected to criticism in recent years. The results of simulation analysis show that the rebound could be reduced to approximately 90.7% if the refined oil pricing mechanism is reformed. In this regard, we suggest further reforms in the current refined oil pricing mechanism. - Highlights: ► We set up the LA-AIDS model to estimate traffic service demand for urban residents. ► The size of the rebound effect for passenger transportation in China is evaluated. ► The rebound effect for passenger transportation in China is 107.2%. ► Reform of oil pricing could reduced the rebound to 90.7%. ► Reform of oil pricing might be an effective method for mitigating rebound effect

    Malaysia is paying a high level of subsidies on the consumption of energy (about 5% of its GDP). Therefore, reforming the energy subsidies, as planned by the government, will have a significant impact on household welfare and energy-intensive sectors, such as the transport sector. This study employs a computable general equilibrium (CGE) model to highlight the transmission channels through which the removal of energy subsidies affects the domestic economy. The findings show that the shock increases real GDP and real investment, while decreasing Malaysian total exports and imports. The removal of energy subsidies also decreases the aggregate energy demand, and, consequently, decreases the level of carbon emissions in the Malaysian economy. In addition, households experience significant falls in their consumption and welfare. The transport sector is significantly influenced through an increase in production costs due to an increase in the prices of intermediate inputs. The total output and total exports of the whole transport sector decrease while its imports increase. In addition, the use of all kinds of transport by households decreases significantly. The Malaysian energy subsidy reform, leads to an initial decrease in CO 2 emissions and demand for electricity, gas, and petroleum products in the entire transport sector. - Highlights: • Malaysia pays a high level of subsidy on consumption of energy. • The transportation sector in this country is the highest energy consumer among others. • A general equilibrium model used to analyse the effects of energy subsidy reform. • The shock increases real GDP and decreases energy and carbon emission in this sector. • It is not beneficial for the transport sector as decreases the output of this sector

    Two years after the implementation of the Health Sector Evolution Plan (HSEP), this study evaluated the effects of the plan on health equity indices. The main indices assessed by the study were the Out-of-Pocket (OOP) health expenditures, the Fairness in Financial Contribution (FFC) to the health system index, the index of households' Catastrophic Health Expenditure (CHE) and the headcount ratio of Impoverishing Health Expenditure (IHE). The per capita share of costs for total health services has been decreased. The lowered costs have been more felt in rural areas, generally due to sharp decrease in inpatient costs. Per capita pay for outpatient services is almost constant or has slightly increased. The reform plan has managed to improve households' Catastrophic Health Expenditure (CHE) index from an average of 2.9% before the implementation of the plan to 2.3% after the plan. The Fairness in Financial Contribution (FFC) to the health system index has worsened from 0.79 to 0.76, and the headcount ratio of Impoverishing Health Expenditure (IHE) index deteriorated after the implementation of plan from 0.34 to 0.50. Considerable improvement, in decreasing the burden of catastrophic hospital costs in low income strata which is about 26% relative to the time before the implementation of the plan can be regarded as the main achievement of the plan, whereas the worsening in the headcount ratio of IHE and FFC are the equity bottlenecks of the plan.

  5. Energy and behavioral impacts of integrative retrofits for residential buildings: What is at stake for building energy policy reforms in northern China?

    2013-01-01

    Based upon the results from extensive building monitoring and surveys on occupant’s behaviors in a representative nine-story apartment building in northern China, building energy simulations were performed to evaluate the impacts of integrative retrofits implemented. Integrative retrofits required by the newer building energy standard produced significant heating-energy savings (i.e., 53%) when compared with baseline buildings commonly built in early 1980s. Taking into account district-heating-system upgrades as part of integrative retrofit measures, a representative apartment building was 66% more efficient than the baseline building. Contrary to expectation, little behavioral change was found in response to the provisions of monetary incentive, billing-method reform, or metering of heating energy use in individual apartment units. Yet this paper identified sizable energy savings potential if occupants’ behavioral changes were to actually happen. This indicates that provisions of financial incentives or individual metering were insufficient for triggering substantial behavioral changes leading toward more energy savings in the current buildings. It is recommended that innovative energy policies, technology upgrades, and education would be needed to promote behavioral changes toward additional energy savings. Finally, measures and strategies to further enhance thermal integrity criteria (e.g., insulations of roof and balcony) are recommended in China’s future building energy policy reforms. - Highlights: ► Integrative retrofits significantly reduce residential heating energy in north China. ► Energy effects of retrofits, incentive, billing and behavioral changes were studied. ► Monetary incentive, control or metering technologies did not lead to behavior change. ► Potential energy savings due to occupants’ behavioral changes are sizable. ► Thermal integrity needs to be enhanced in future building standards and policies.

  6. Energy wealth and tax reform in Russia and Kazakhstan

    Resource-rich states throughout the developing world are prone to rent-seeking, excessive borrowing, wasteful spending, and unbalanced growth as well as states with weak institutions and authoritarian regimes. Are the five energy-rich Soviet successor states necessarily doomed to repeat this experience, often referred to as the 'resource curse'? This paper advances and tests the hypothesis that Russia and Kazakhstan are more likely to avoid the 'resource curse' than Uzbekistan, Turkmenistan, and Azerbaijan because they privatized their energy sectors. Specifically, we find that privatization offers a potential path out of the 'resource curse' when it involves a transfer of ownership to domestic actors. Although Kazakhstan initially appeared to be developing a viable tax regime in response to foreign investors, over the long term Kazakhstan's tax regime has become increasingly volatile and dependent upon these foreign investors. In contrast, domestic oil companies are helping to foster the development of an increasingly viable tax regime in Russia. (author)

    In this report, we use a dynamic AGE model to study the effects of the energy tax reform that took place in 2011 and is to be completed by 2015. We construct a counterfactual baseline which evaluates, how the economy would develop had the reform not been implemented. We find that the reform curbs domestic consumption and pushes domestic wages down compared to the baseline, improving the country's external balance. We also study the effects of the 2009 removal of a part of the employers' social security contributions, which the energy tax reform was intended to finance. The 2009 reform increased overall labour demand, resulting in higher wages and higher domestic demand, which had the opposite effects on external balance. (orig.)

    The typical ingredients of energy reforms in the European Union (EU) in the 1990s were full or partial privatization, vertical disintegration and liberalization. This paper analyses the effects of energy reforms on the probability of households experiencing deprivation, defined as difficulty in paying the bills. We use two sets of micro-data. First, the European Community Household Panel (ECHP), a large EU survey, offers evidence on people who report having been unable to pay scheduled utility bills. We consider seven European countries: Denmark, Belgium, France, Ireland, Italy, the Netherlands and Spain, and eight ECHP waves (1994-2001), with around 28,000 observations. Second, we also use micro-data from the European Statistics on Income and Living Conditions survey (EU-SILC) 2004-2005, with around 84,000 observations. The countries included are Belgium, France, Ireland, Italy, Spain, Austria, Finland, Luxembourg, Norway and Sweden. As indicators of regulatory reforms in the same countries and years we use ECTR (formerly REGREF), a database provided by the OECD. In both samples we find evidence that privatization increases the probability of households experiencing deprivation. Vertical disintegration has a similar effect and also increases the persistence in the status of household deprivation. Liberalization has no statistically significant effect. We discuss possible interpretations of these findings.

    Full Text Available This work presents a method to analyze hydrogen production by biomass gasification, as well as electric power generation in small scale fuel cells. The proposed methodology is the thermodynamic modeling of a reaction system for the conversion of methane and carbon monoxide (steam reforming, as well as the energy balance of gaseous flow purification in PSA (Pressure Swing Adsorption is used with eight types of gasification gases in this study. The electric power is generated by electrochemical hydrogen conversion in fuel cell type PEMFC (Proton Exchange Membrane Fuel Cell. Energy and exergy analyses are applied to evaluate the performance of the system model. The simulation demonstrates that hydrogen production varies with the operation temperature of the reforming reactor and with the composition of the gas mixture. The maximum H2 mole fraction (0.6-0.64 mol.mol-1 and exergetic efficiency of 91- 92.5% for the reforming reactor are achieved when gas mixtures of higher quality such as: GGAS2, GGAS4 and GGAS5 are used. The use of those gas mixtures for electric power generation results in lower irreversibility and higher exergetic efficiency of 30-30.5%.

    Full Text Available In 2014, the Mexican government approved a bold energy reform that allows private energy companies to freely participate in the energy market (something prohibited during the previous eight decades. This reform is expected to significantly restructure the energy sector and boost and diversify the energy production. Moreover, changes in the energy sector and production might lead to structural changes in the rest of the economy and ultimately generate significant economic benefits for the country. Nevertheless, the fundamental role of the energy sector in this oil producing country makes the potential impacts of the reform complex to forecast. The objective of the study is to analyze the current state, evolution, and driving factors of the total primary energy use in Mexico in 2003–2012 (prior to the implementation of the reform as a precedent for future analyses of impacts of the energy reform. The results show three driving factors of the evolution of primary energy use: final non-energy demand, direct energy intensity, and economic structure. Also, it was found that the energy sector has been in a precarious situation regarding its structure and efficiency. However, this situation had a small effect on the evolution of primary energy use.

    2010-07-15

    The research project 'Energy efficient selective reforming of hydrocarbons', funded by the Swedish and Energinet.dk Agency has now reached its end. The report is an overview of the work. Details of the work within the different areas can be found in the reports from each part. In this project, an innovative method for tar removal and reformation of hydrocarbons was investigated: Chemical Looping Reforming (CLR). This gas treatment has the potential to be economically competitive, reliable and environmentally friendly (due to higher energy efficiency, amongst others). The aim of the CLR is to 1) eliminate downstream problems with tar 2) simplify the energy recovery from the hot product gas 3) selectively save lighter hydrocarbons for the production of synthetic natural gas (SNG). A guarantor for the outcome of the project is the engagement of Goeteborg Energi, which has a commitment to build a 20 MW output SNG plant by 2012. DTU (Danish Technical University) is responsible for carrying out the laboratorial part, where different oxygen carriers for the CLR have been considering their capability of selectively reforming hydrocarbons. The conclusion was that, of the four carriers tested, the Mn and Ni40 was the most promising. CUT (Chalmers University of Technology) has installed a 600 W CLR unit connected to a slipstream from the gasifier. During the firing season 2010 the CLR has been tested with raw gas for 36 hours and the results so far show that the equipment works as intended and that it can reduce the amount of tars substantially. GE (Goeteborg Energi AB) together with SEP (Scandinavian Energy Project AB) and CUT have studied the integration of a methane production plant to an existing boiler. The main focus of the study has been the gasifier and the CLR. The integration of a 100 MW methane production plant is estimated to cost 1.3-2.4 billion SEK. The different work packages have altogether shown that a CLR is a possible solution to the tar problem

    The actual distribution of powers about energy is more discussed after the reform of the art. 117 of the constitution. In front of a contradiction in terms, the government is been obliged to take some emergency solutions, that are witnessed by the reiterated petition to the urgent decree. It was a question of some measures justified, about the matter, from several points of view but they risked cracking seriously the relation between state and regions. The system of energy has naturally and objectively a national configuration and so people demand how the decentralization politics of the competencies has to be interpreted, that was introduced by the reform of title 5. of the constitution. The art. 117 of the Constitution implies the energy among the subjects of competing law, and let the State to determinate the basic principles, in order to ensure the basic homogeneity of the subject. The limits of such regional power are: 1) the limit of national interest (disappeared from the literal diction of the art. 117, but there are debates above its survival; 2) the basic principles role; 3) the normative settlement and the admissibility of 'accomodating' state detail norms in the subordinate matters to the competing legislative power. Even if in the Constitutional text does not exist any longer national interest just like a 'passe-par tout' to limit and coerce the regional interventions, this does not mean that national interest are disappeared: national interest has one of its substantial variability and only the State can be its interpreter, as only representative of the joint republican interest. The Consulta has recently asserted that if on one hand the Constitution has moved the centre of the legislative power in aid of the districts, on the other has strengthened the role and the importance of the basic principles; at least, it has done it for the subjects of competing law. In fact, someone confirmed that the principles may be deducible without an explicit

    On going through the catalogue of ideas for a reform it becomes evident that a fundamental revision of the law is not needed, rather that this could bring about a deterioration of the normative situation. The often called for but never achieved consensus in the nuclear energy issue has in practice proved to be a problem of law execution. Legislative measures can neither solve this problem nor bring about the necessary consensus. The present law goes towards but falls short of creating the basis of trust, necessary for economically efficient action in the area of nuclear energy utilization. Any shift of the borders defining the consensus through new acts of law-making will simultaneously shift the borders of the area of trust and must influence future entrepreneurical decisions. Seen in this light any amendment to the Atomic Energy Law bears implications reaching far beyond its subject-matter. (orig./HSCH) [de

    India's transmission and distribution losses are among the highest in the world. When non-technical losses such as energy theft are included in the total, losses go as high as 65% in some states and average about 35-40%. The financial loss has been estimated at 1.5% of the national GDP. These act as a major deterrent to the private as well as global investments in the sector. To address the issue of Aggregate Transmission and Commercial (AT&C) losses funding mechanism was introduced for in the form of the Accelerated Power Development Reforms Programme (APDRP).

    This study investigates the emergence of energy markets by testing for convergence of energy prices with a new dataset on energy spot prices in 35 major cities in China. Both descriptive statistics and unit root are employed to test the convergence of energy prices for each of four fuel price series. The whole study period is divided into two sub-periods in order to reconcile the gradual energy reforms. The results show the steady improvement in energy market performance in China, especially during the second sub-period, which suggests that the market appears to be playing an increasing role in determining energy prices. While panel unit root tests show energy markets are integrated in China as a whole, city-by-city univariate unit root tests suggest that there are still many regional energy markets, probably because energy reserves (especially coal) vary widely across regions. Since China's energy economy is gradually moving towards market-oriented mechanisms, the existing literature may become obsolete soon.

    The development of an energy reform strategy based on the market economy so as to introduce competition in the market segments is of crucial importance for provision of a stable and favourable environment for energy investments. Reform strategies have begun developing in most of the 12 Mediterranean Countries of North Africa and the Eastern Mediterranean, especially in the context of the Euro-Mediterranean Free Trade Area. Even though energy sector reforms have been initiated, they are still at an early stage in most of these countries. The majority of energy utilities remain state owned, vertically integrated monopolies. Few of these countries have established energy regulators, and where they have, these institutions have many difficulties in effective development. In addition, competition is virtually absent from the sector, and private participation has been confined to independent power plants, which tend to be introduced into unreformed sectors. The aim of this paper is to propose energy reform strategies for the reform of the sector by 2010 in terms of the development of the regional oil, gas and electricity sectors in these countries

    This paper investigates the impact of energy on China's industrial sustainability by using a novel approach to estimate real total factor productivity. The growth accounting indicates that the substantial industrial reforms in China have led to productivity growth. Energy and capital are also important factors driving China's industrial growth. Productivity growth in China's industry is mostly attributable to the high-tech light industrial sectors. - Highlights: ► Productivity has become the most important growth engine in majority of sectors. ► Energy and capital are also important factors promoting China's industrial growth. ► The productivity improvement is more attributable to high-tech light industry. ► The heavy industry performs worse than the light one in terms of productivity

  7. Energy measurements from betatron oscillations

    1989-03-01

    In the Stanford Linear Collider the electron beam is accelerated from 1--50 GeV in a distance of 3 km. The energy is measured and corrected at the end with an energy feedback loop. There are no bends within the linear accelerator itself, so no intermediate energy measurements are made. Errors in the energy profile due to mis-phasing of the rf, or due to calibration errors in the klystrons' rf outputs are difficult to detect. As the total betatron phase advance down the accelerator is about 30 /times/ 2π, an energy error of a few percent can cause a large error in the total phase advance. This in turn degrades the performance of auto-steering programs. We have developed a diagnostic program which generates and measures several betatron oscillations in the accelerator. It then analyzes this oscillation, looking for frequency changes which indicate energy errors. One can then compensate for or correct these energy errors. 6 refs., 1 fig

    With its GDP growing at an average rate of 9.8% for the last seventeen years, China has the world's fastest growing economy. This rapid pace of growth and industrialization has caused economic strain because fuel production cannot keep pace with demand, If China allows this situation to continue, significant oil imports will be necessary. In 1993, the industrial sector contributed 56% to China's GDP and consumed 61% of the total final energy. The industrial sector will remain the largest energy consumer in China well into the next century. According to China's Ninth Five-Year Plan (1996--2000), China will strengthen its ability to develop new products and will use technological advancement to promote industrial development. The Plan calls for special attention in four major areas: microelectronics technology, digital technology, software technology, and network technology. Given China's emphasis on developing light industries and on improving industrial sector energy efficiency, it is important to study the future energy demand of the industrial sector. Two scenarios for future energy requirements are studied through the year 2015: a Business As Usual (BASU) scenario and an Energy Efficient (EE) scenario. The study evaluates China's current economic reform policies and energy efficiency policies. The results of this evaluation are used to assign appropriate growth rates to industrial GDP and the industrial energy intensity for both scenarios. Results from the two scenarios are compared and analyzed

    Measuring energy security or resilience in energy is, in the main, confined to indicators which are used for comparative purposes or to show trends rather than provide empirical evidence of resilience to unpredicted crises. In this paper, the electricity systems of the individual states within the United States of America are analysed for their response to the 1973-1982 and the 2003-2012 oil price shocks. Empirical evidence is sought for elements which are present in systems that experience r...

    Pachauri, Shonali; Spreng, Daniel

    2011-01-01

    This article undertakes a review of alternative measures and indicators of energy poverty targeted to specific audiences and for particular purposes. At the national and international scales there have been some efforts for constructing measures of energy poverty. However, much more needs to be done to develop an internationally consistent measurement framework and to put in place data collection systems that will enable regular reporting. At the programme and project level, indicator systems by necessity need to be designed for specific purposes. Nevertheless, the article proposes that in many instances it is desirable to widen the scope of metrics used for designing and evaluating policies and programmes. In the past, monitoring and evaluation indicators have focused largely on outputs, service delivery or dissemination. Central to the recommendations laid out in the paper is the call for widening the focus of evaluation and necessity to design indicators that adequately assess the needs of beneficiaries and describe the living conditions of families and communities, who are targeted by such programmes and initiatives. - Highlights: ► Consistent measurement frameworks and regular data collection systems on energy poverty are needed. ► Metrics used for designing and evaluating energy access programmes should be widened. ► Indicators that adequately assess needs and describe living conditions of targeted beneficiaries are required.

    Due to the strategic importance, the energy industry in Poland was excluded from the privatisation up to the year 1996. In 1996, the deregulation and privatisation of the energy industry in Poland was induced by the outline plan of the implementation of the fundamentals of the energy policy up to the year 2020 as well as by the de-monopolization and privatisation of the electric energy. In October, 2012, the Polish Ministry of Economy finished the draft of a correspondent energy legislation consisting of three single laws - the so-called energy threepack. The authors of the contribution under consideration characterize the development lines of the Polish energy industry and review on the expected new regulations of the energy law.

  14. Energy and CO2 emissions performance in China's regional economies: Do market-oriented reforms matter?

    Lin, Boqiang; Du, Kerui

    2015-01-01

    This paper employs a newly developed non-radial directional distance function to evaluate China's regional energy and CO 2 emission performance for the period 1997–2009. Moreover, we analyze the impact of China's market-oriented reform on China's regional energy and carbon efficiency. The main findings are as follows. First, most of China's regions did not perform efficiently in energy use and CO 2 emissions. Provinces in the east area generally performed better than those in the central and west areas. By contrast, provinces in the west area generally evidenced the lowest efficiency. Second, Market-oriented reforms, especially the promotion of factor market, were found to have positive effect on the efficiency of energy use and CO 2 emissions. Third, the share of coal in the total energy consumption and the expansion of the industrial sector were found to be negatively correlated with China's regional energy and CO 2 emissions performance. Based on the empirical findings, we provide policy suggestions for enhancing energy and carbon efficiency in China. - Highlights: • A newly developed NDDF are applied to evaluate China's energy and carbon performance. • Most of China's regions did not perform efficiently in energy use and CO 2 emissions. • Market-oriented reforms contributed to improving China's energy and carbon efficiency

    2002-09-01

    This article argues the case for introducing new energy policies in Ethiopia that will ensure energy initiatives for rural development meet the desired expectations. A review of the rural energy sector in Ethiopia is presented. Rural communities have for centuries relied solely on traditional biomass energy sources, human and animal power. In addition, sample findings show that the basic stock of traditional biomass energy resources is dwindling fast for two reasons: one, due to rapid population growth; and two, due to the absence of energy substitutes for traditional energy sources. Renewable energy technologies and other modern energy technologies are almost non-existent. In terms of budgetary allocation, rural energy development has not received a fair share of public investment in comparison to education, rural road construction and health. A key policy recommendation made in this article is the need for commitment from concerned authorities to the use of renewables for spurring rural development. This could be done through increasing the budget allocation to rural energy, which is currently negligible. Other policy recommendations include the modification of existing institutional frameworks for rural energy delivery, and the design and implementation of appropriate rural energy initiatives suitable for productive activities and sustainable development.

    The U.S. health care system is currently experiencing profound change. Pressure to improve the quality of patient care and control costs have caused a rapid shift from traditional volume-driven fee-for-service reimbursement to value-based payment models. Under the 2015 Medicare Access and Children's Health Insurance Program Reauthorization Act, providers will be evaluated on the basis of quality and cost efficiency and ultimately receive adjusted reimbursement as per their performance. Although current performance metrics do not incorporate patient-reported outcome measures (PROMs), many wonder whether and how PROMs will eventually fit into value-based payment reform. On November 17, 2016, the second annual Patient-Reported Outcomes in Healthcare Conference brought together international stakeholders across all health care disciplines to discuss the potential role of PROs in value-based health care reform. The purpose of this article was to summarize the findings from this conference in the context of recent literature and guidelines to inform implementation of PROs in value-based payment models. Recommendations for evaluating key perspectives and measurement goals are made to facilitate appropriate use of PROMs to best benefit and amplify the voice of our patients.

    The Slovak Republic faces the task to secure conditions for a long-term economic growth. A crucial precondition for an efficient implementation of economic and social measures is the knowledge of the status quo and of the impacts on the economy and the society as a whole, to be expected from the relevant measures and it is important to focus on short-term as well as on long-term goals. For a successful implementation of many economic and social measures citizens' acceptance is needed. Therefore, the non-governmental, non-profit organisation Institute for Economic and Social Reforms INEKO aims to make the public more familiar with the nature of economic and social processes in the country and abroad, and to eliminate, through economic research and educational activities, hindrances to a long-term positive development of the Slovak economy and society.

    2016-12-01

    We develop and implement what we believe is the first conceptually valid health-inclusive poverty measure (HIPM) - a measure that includes health care or insurance in the poverty needs threshold and health insurance benefits in family resources - and we discuss its limitations. Building on the Census Bureau's Supplemental Poverty Measure, we construct a pilot HIPM for the under-65 population under ACA-like health reform in Massachusetts. This pilot demonstrates the practicality, face validity and value of a HIPM. Results suggest that public health insurance benefits and premium subsidies accounted for a substantial, one-third reduction in the health inclusive poverty rate. Copyright © 2016 Elsevier B.V.

    The use of fuel cells is a promising technology in the conversion of chemical to electrical energy. Due to environmental concerns related to the reduction of atmospheric pollution and greenhouse gases emissions such as CO 2 , NO x and hydrocarbons, there have been many researches about fuel cells using hydrogen as fuel. Hydrogen gas can be produced by several routes; a promising one is the steam reforming of ethanol. This route may become an important industrial process, especially for sugarcane producing countries. Ethanol is renewable energy and presents several advantages over other sources related to natural availability, storage and handling safety. In order to contribute to the understanding of the steam reforming of ethanol inside the reformer, this work displays a detailed thermodynamic analysis of the ethanol/water system, in the temperature range of 500-1200K, considering different H 2 O/ethanol reforming ratios. The equilibrium determinations were done with the help of the Gibbs energy minimization method using the Generalized Reduced Gradient algorithm (GRG). Based on literature data, the species considered in calculations were: H 2 , H 2 O, CO, CO 2 , CH 4 , C 2 H 4 , CH 3 CHO, C 2 H 5 OH (gas phase) and C gr . (graphite phase). The thermodynamic conditions for carbon deposition (probably soot) on catalyst during gas reforming were analyzed, in order to establish temperature ranges and H 2 O/ethanol ratios where carbon precipitation is not thermodynamically feasible. Experimental results from literature show that carbon deposition causes catalyst deactivation during reforming. This deactivation is due to encapsulating carbon that covers active phases on a catalyst substrate, e.g. Ni over Al 2 O 3 . In the present study, a mathematical relationship between Lagrange multipliers and the carbon activity (with reference to the graphite phase) was deduced, unveiling the carbon activity in the reformer atmosphere. From this, it is possible to foreseen if soot

    Full Text Available This project aims to develop a measurement of solar energy using Arduino Board technology. In this research, four parameters that been measured are temperature, light intensity, voltage and current. The temperature was measured using temperature sensor. The light intensity was measured using light dependent resistor (LDR sensor. The voltage was measured using the voltage divider because the voltage generated by the solar panel are large for the Arduino as receiver. Lastly for the current was measured using the current sensor module that can sense the current generated by the solar panel. These parameters as the input value for the Arduino and the output was display at the Liquid Crystal Display (LCD screen. The LCD screen display output of the temperature, the light intensity, the voltage and the current value. The purpose of Arduino to convert the analog input of parameter to the digital output and display via LCD screen. Other than that, this project also involve with a design to ensure that device case are easy to be carry around.

  1. Renewable energy: Method and measures

    Nilsen, Trond Hartvedt

    2003-01-01

    The thesis presents various possibilities for renewable energy in Norway. The wind power would give a practical and economic alternative. The external costs for the wind power would be moderate. In chapter 3 the utility cost analysis for renewable alternatives are studied relative to the macroeconomic efficiency. Some methodical problems and how these analyses are used are reviewed. In the practical utility cost analyses wind power is studied relative to gas power which is the non-renewable alternative present in Norway today. A qualitative part is included. It is not possible to determine whether wind power is preferable to gas power in the macroeconomic perspective. Wind power would be the choice if high environmental and CO2 cleaning costs are expected. The first conclusion to be drawn is that it is difficult to decide whether wind power is the best solution based on cost benefit analysis. However, the alternative seems to be quite robust in the analysis. Due to the central position the energy supplies have in the society this business should be heavily regulated. The sector is also overtaxed as a reduction in consumption is desired. The analysis shows that the system does not function perfectly. The thesis surveys various measures for improving the renewable energy supply and focuses on the wind power. A model for and analysis of the measures are carried out and resulted in a second conclusion. The measures have various properties as to the influence on the market. A subsidy is a fine measure for stimulation production of green power while a tax reduces efficiently the production of black power. A system with green licenses in combination with a subsidy and a tax would be preferable as to increasing the part of renewable energy of the total production. It is therefore necessary to have clearly defined goals and use suitable measures for achieving them. The costs of wind power is falling and it would therefore soon be macroeconomic profitable. It is also

    Mexico's 2009 "narcomenudeo reform" decriminalized small amounts of drugs, shifting some drug law enforcement to the states and mandating drug treatment diversion instead of incarceration. Data from Tijuana suggested limited implementation of this harm reduction-oriented policy. We studied whether a police education program (PEP) improved officers' drug and syringe policy knowledge, and aimed to identify participant characteristics associated with improvement of drug policy knowledge. Pre- and post-training surveys were self-administered by municipal police officers to measure legal knowledge. Training impact was assessed through matched paired nominal data using McNemar's tests. Multivariable logistic regression was used to identify predictors of improved legal knowledge, as measured by officers' ability to identify conceptual legal provisions related to syringe possession and thresholds of drugs covered under the reform. Of 1750 respondents comparing pre- versus post training, officers reported significant improvement (p < 0.001) in their technical understanding of syringe possession (56 to 91%) and drug amounts decriminalized, including marijuana (9 to 52%), heroin (8 to 71%), and methamphetamine (7 to 70%). The training was associated with even greater success in improving conceptual legal knowledge for syringe possession (67 to 96%) (p < 0.001), marijuana (16 to 91%), heroin (11 to 91%), and methamphetamine (11 to 89%). In multivariable modeling, those with at least a high school education were more likely to exhibit improvement of conceptual legal knowledge of syringe possession (adjusted odds ratio [aOR] 2.6, 95% CI 1.4-3.2) and decriminalization for heroin (aOR 2.7, 95% CI 1.3-4.3), methamphetamine (aOR 2.2, 95% CI 1.4-3.2), and marijuana (aOR 2.5, 95% CI 1.6-4). Drug policy reform is often necessary, but not sufficient to achieve public health goals because of gaps in translating formal laws to policing practice. To close such gaps, PEP initiatives

  3. Rasch Validation of a Measure of Reform-Oriented Science Teaching Practices

    Growing evidence from recent curriculum documents and previous research suggests that reform-oriented science teaching practices promote students' conceptual understanding, levels of achievement, and motivation to learn, especially when students are actively engaged in constructing their ideas through scientific inquiries. However, it is difficult to identify to what extent science teachers engage students in reform-oriented teaching practices (RTPs) in their science classrooms. In order to exactly diagnose the current status of science teachers' implementation of the RTPs, a valid and reliable instrument tool is needed. The principles of validity and reliability are fundamental cornerstones in developing a robust measurement tool. As such, this study was motivated by the desire to point out the limitations of the existing statistical and psychometric analyses and to further examine the validation of the RTP survey instrument. This paper thus aims at calibrating the items of the RTPs for science teachers using the Rasch model. The survey instrument scale was adapted from the 2012 National Survey of Science and Mathematics Education (NSSME) data. A total of 3701 science teachers from 1403 schools from across the USA participated in the NSSME survey. After calibrating the RTP items and persons on the same scale, the RTP instrument well represented the population of US science teachers. Model-data fit determined by Infit and Outfit statistics was within an appropriate range (0.5-1.5), supporting the unidimensional structure of the RTPs. The ordered category thresholds and the probability of the thresholds showed that the five-point rating scale functioned well. The results of this study support the use of the RTP measure from the 2012 NSSME in assessing usage of RTPs.

    2006-01-01

    This paper summarizes the first comprehensive estimation of California's electricity avoided costs since the state reformed its electricity market. It describes avoided cost estimates that vary by time and location, thus facilitating targeted design, funding, and marketing of demand-side management (DSM) and energy efficiency (EE) programs that could not have occurred under the previous methodology of system average cost estimation. The approach, data, and results reflect two important market structure changes: (a) wholesale spot and forward markets now supply electricity commodities to load serving entities; and (b) the evolution of an emissions market that internalizes and prices some of the externalities of electricity generation. The paper also introduces the multiplier effect of a price reduction due to DSM/EE implementation on electricity bills of all consumers. It affirms that area- and time-specific avoided cost estimates can improve the allocation of the state's public funding for DSM/EE programs, a finding that could benefit other parts of North America (e.g. Ontario and New York), which have undergone electricity deregulation.

  5. Building state capacity in Russia: A case study of energy sector reform, 1992--1998

    Science.gov (United States)

    Kim, Younkyoo

    This study seeks an explanation for the neglect of state building in Russia. The major hypothesis is that dependence on external rent leads to the weakness of the state. Three intervening variables---transaction costs, bargaining power of the state, and discount rates---are posited to explain variance on the dependent variable, the weakness of the state. Based on the exploration of three dimensions of energy sector reform, the dissertation argues that in the short run resource rents may be the only reliable and adequate source of finance for the Russian government. The division of resource rents among the many claimants (state vs. business, state vs. society, Moscow vs. regions, and Russia vs. foreign companies), it submits, will pose a stringent test of the viability of democratic governance in Russia. The dissertation concludes that some evidence indicates that Russia has in fact met the characteristics of the rentier state. The greater reliance on a large resource sector for revenue has led to high transaction costs of tax collection, weak bargaining power of the state, and high discount rates of government officials in Russia.

    1993-01-01

    The failure of both democracies and revolutions in Latin America is due to the fact that the State has been trusted with political, economic and social organization, instead of relying on the motivations and capabilities of intermediate associations and the individual members of society. Therefore, the process of change is not just a matter of national decision; it is something that must, and will, take place. Ecuador understands perfectly well the need for reform. Major laws have already been enacted, and a bill for modernization of the State is currently under consideration by congress. The concept of modernization and, therefore, change does not merely imply new laws, simplified procedures or easier operations; it basically means allowing the creative forces of individuals, enterprises and intermediate associations to play a more influential role. As in other Latin American countries, in Ecuador there can be no real modernization, no real change in society without a major revolution in energy and telecommunications. Thus, two important laws have been drafted to demonopolize petroleum and electric power operations and open them up both to national and foreign private sector participation

    2016-01-01

    A comprehensive research in the field of energy poverty is undertaken in this paper, in an attempt to highlight the great vulnerability of Greek households on energy poverty, in the middle of a severe economic crisis. Till now, Greek energy policy has been considered insufficient to tackle energy poverty issues, as focusing mainly on short-term rather than permanent solutions. A primary survey has been conducted, recording objective data of energy expenses as well as subjective perceptions about housing conditions. The findings showed that, under the objective expenditure-based method, 58% of Greek households are energy poor. Among households under the poverty threshold, the energy poverty rate exceeds 90%. Existing and new subjective indicators shed light on other aspects of energy poverty, such as the level of thermal comfort at home, damp problems detected, restriction of other essential needs in order to manage energy payments, etc. Some interesting conclusions are also drawn by exploring the relationship between various indicators. It appears that households considered energy poor are not identical when examined by objective and subjective indicators. However, different indicators complement each other by capturing different aspects of the problem and provide a broader overview of the issue. - Highlights: •58% of Greek households are energy poor. •75% of Greek households have reduced other essentials in favor of energy needs. •Combination of objective and subjective indicators captures better energy poverty. •Greek energy policy has failed to tackle energy poverty issues.

    Urban environments in the United States account for a majority of the population and, as such, require large volumes of treated drinking water supply and wastewater removal, both of which need energy. Despite the large share of water that urban environments demand, there is limited accounting of these water resources outside of the city itself. In this study, we provide and analyze a database of drinking water and wastewater utility flows and energy that comprise anthropogenic fluxes of water through the urban environment. We present statistical analyses of the database at an annual, spatial, and intra-annual scale. The average daily per person water flux is estimated as 563 liters of drinking water and 496 liters of wastewater, requiring 340 kWh/1000 m3 and 430 kWh/1000 m3 of energy, respectively, to treat these resources. This energy demand accounts for 1% of the total annual electricity production of the United States. Additionally, the water and embedded energy loss associated with non-revenue water (estimated at 15.8% annually) accounts for 9.1 km3of water and 3600 GWh, enough electricity to power 300,000 U.S. households annually. Through the analysis and benchmarking of the current state of urban water fluxes, we propose the term `blue city,' which promotes urban sustainability and conservation policy focusing on water resources. As the nation's water resources become scarcer and more unpredictable, it is essential to include water resources in urban sustainability planning and continue data collection of these vital resources.

    Processes and technologies to produce hydrogen synergistically by the steam reforming reaction using fossil fuels and nuclear heat are reviewed. Formulas of chemical reactions, required heats for reactions, saving of fuel consumption or reduction of carbon dioxide emission, possible processes and other prospects are examined for such fossil fuels as natural gas, petroleum and coal. The 'membrane reformer' steam reforming with recirculation of reaction products in a closed loop configuration is considered to be the most advantageous among various synergistic hydrogen production methods. Typical merits of this method are: nuclear heat supply at medium temperature below 600 deg. C, compact plant size and membrane area for hydrogen production, efficient conversion of feed fuel, appreciable reduction of carbon dioxide emission, high purity hydrogen without any additional process, and ease of separating carbon dioxide for future sequestration requirements. With all these benefits, the synergistic production of hydrogen by membrane reformer using fossil fuels and nuclear energy can be an effective solution in this century for the world which has to use. fossil fuels any way to some extent while reducing carbon dioxide emission. For both the fossil fuels industry and the nuclear industry, which are under constraint of resource, environment and economy, this production method will be a viable symbiosis strategy for the coming hydrogen economy era.

    Full Text Available Abstract Background Mexico’s 2009 “narcomenudeo reform” decriminalized small amounts of drugs, shifting some drug law enforcement to the states and mandating drug treatment diversion instead of incarceration. Data from Tijuana suggested limited implementation of this harm reduction-oriented policy. We studied whether a police education program (PEP improved officers’ drug and syringe policy knowledge, and aimed to identify participant characteristics associated with improvement of drug policy knowledge. Methods Pre- and post-training surveys were self-administered by municipal police officers to measure legal knowledge. Training impact was assessed through matched paired nominal data using McNemar’s tests. Multivariable logistic regression was used to identify predictors of improved legal knowledge, as measured by officers’ ability to identify conceptual legal provisions related to syringe possession and thresholds of drugs covered under the reform. Results Of 1750 respondents comparing pre- versus post training, officers reported significant improvement (p < 0.001 in their technical understanding of syringe possession (56 to 91% and drug amounts decriminalized, including marijuana (9 to 52%, heroin (8 to 71%, and methamphetamine (7 to 70%. The training was associated with even greater success in improving conceptual legal knowledge for syringe possession (67 to 96% (p < 0.001, marijuana (16 to 91%, heroin (11 to 91%, and methamphetamine (11 to 89%. In multivariable modeling, those with at least a high school education were more likely to exhibit improvement of conceptual legal knowledge of syringe possession (adjusted odds ratio [aOR] 2.6, 95% CI 1.4–3.2 and decriminalization for heroin (aOR 2.7, 95% CI 1.3–4.3, methamphetamine (aOR 2.2, 95% CI 1.4–3.2, and marijuana (aOR 2.5, 95% CI 1.6–4.

    Wohlgemuth, N.

    1999-01-01

    Worldwide, the electricity industry is in the process of undergoing fundamental transitions. The reform process typically involves one or more of the following changes: commercialisation, privatisation, unbundling/restructuring and introduction of competition. The environmental impacts of these changes pull in different directions. There is concern that restructured electricity markets may not always incorporate adequately the environmental impacts of electricity resource development and consumption decisions. However, the electricity sector reform process also offers an opportunity to promote positive environmental changes: because the sector is already in flux, it may be easier to address environmental issues. The paper gives an overview of power sector reform in six countries where reforms have already been implemented, and concludes that reform measures will have to be accompanied by competitively neutral regulations in order to stimulate investment in environmentally sound technologies, including renewable and energy efficient technologies.

    The fuel cells transform the chemical energy stored in the connection H-H of the H 2 molecule in electric energy and water vapor when is combines with the oxygen. Even when the hydrogen has a high potential as energy source, its handling is difficult (storage and transport). This has motivated the search of hydrogen production methods in situ starting from liquid fuels like the methanol or ethanol through the reaction of reforming. The methanol is a fuel of easy availability for fuel cells with electronic applications and of transport. Although the methanol energy density is approximately half of the gasoline and diesel, it is more reagent and can be used directly in fuel cells or can also be reformed to low temperatures for the hydrogen obtaining to be used in fuel cells of proton exchange. In this article the results obtained of the systems, Cu-Ni/ZrO 2 and Ag-Au(1-D)-CeO 2 are presented and can be competitive to generate H 2 and being used in the fuel cells to generate energy.

  15. Measuring energy efficiency: Is energy intensity a good evidence base?

    International Nuclear Information System (INIS)

    Proskuryakova, L.; Kovalev, A.

    2015-01-01

    Highlights: • Energy intensity measure reflects consumption, not energy efficiency. • Thermodynamic indicators should describe energy efficiency at all levels. • These indicators should have no reference to economic or financial parameters. • A set of energy efficiency indicators should satisfy several basic principles. • There are trade-offs between energy efficiency, power and costs. - Abstract: There is a widespread assumption in energy statistics and econometrics that energy intensity and energy efficiency are equivalent measures of energy performance of economies. The paper points to the discrepancy between the engineering concept of energy efficiency and the energy intensity as it is understood in macroeconomic statistics. This double discrepancy concerns definitions (while engineering concept of energy efficiency is based on the thermodynamic definition, energy intensity includes economic measures) and use. With regard to the latter, the authors conclude that energy intensity can only provide indirect and delayed evidence of technological and engineering energy efficiency of energy conversion processes, which entails shortcomings for management and policymaking. Therefore, we suggest to stop considering subsectoral, sectoral and other levels of energy intensities as aggregates of lower-level energy efficiency. It is suggested that the insufficiency of energy intensity indicators can be compensated with the introduction of thermodynamic indicators describing energy efficiency at the physical, technological, enterprise, sub-sector, sectoral and national levels without references to any economic or financial parameters. Structured statistical data on thermodynamic efficiency is offered as a better option for identifying break-through technologies and technological bottle-necks that constrain efficiency advancements. It is also suggested that macro-level thermodynamic indicators should be based on the thermodynamic first law efficiency and the energy

    This note discusses the overall ATLAS detector performance for the reconstruction of the missing transverse energy, ETmiss. Two reconstruction algorithms are discussed and their performance is evaluated for a variety of simulated physics processes which probe different topologies and different total transverse energy regimes. In addition, effects of fake ETmiss, resulting from instrumental effects and from false reconstructions are investigated. Finally, studies with first data, corresponding to an integrated luminosity of 100 pb-1, are suggested which can be used to assess and calibrate the ETmiss performance at the startup of data taking.

    2015-01-01

    Full Text Available The increase in energy consumption in buildings causes the need to propose energy efficiency improvement measures. Urban planning in accordance with micro location conditions can lead to energy consumption reduction in buildings through the passive solar design. While satisfying the thermal comfort to the user space purpose, energy efficiency can be achieved by optimizing the architectural and construction parameters such as shape of the building, envelope structure and the percentage of glazing. The improvement of the proposed measures, including the use of renewable energy sources, can meet requirements of Directive 2010/31 / EU of 'nearly zero energy buildings'.

    Mexico has entered in an important dynamic of structural changes in the energy area, proof of this, it is the Energy Reform 2013 and the Energy Transition Law published the last December 24th, 2015, thus it is important to carry out studies of the impacts of future politics in the consumption of the population, so this study estimate an energy demand system using microdata collected from 97,817 households in a National Households Income and Expenditure Survey (ENIGH acronyms in Spanish, Encuesta Nacional de Ingresos y Gastos de los Hogares) in the 20-years period from 1994 to 2014. The magnitudes of all the fuels are smaller than one indicating that electricity, LPG, gasoline and public transport are normal goods, while LPG is the most inelastic energy source. The geographic factor shows that households in the north of Mexico tend to consume more gasoline, whereas in the south of the country, the lowest share of LPG expenditure is reported. The rigorous evaluation of energy demanded in households will help policy makers to put forward more efficient reforms. - Highlights: • The electricity, LPG, gasoline and public transport are normal goods. • LPG is the most inelastic energy source. • The north of Mexico tend to consume more gasoline. • Evidence of complement between personal vehicle and public transport.

    The fuel cell has many potential applications, from power sources for electric hybrid vehicles to small power plants for commercial buildings. The choice of fuel will be critical to the pace of its commercialization. This paper reviews the various liquid fuels being considered as an alternative to direct hydrogen gas for the fuel cell application, presents calculations of the hydrogen and carbon dioxide yields from autothermal reforming of candidate liquid fuels, and reports the product gas composition measured from the autothermal reforming of a synthetic fuel in a micro-reactor. The hydrogen yield for a synthetic paraffin fuel produced by a cobalt-based Fischer-Tropsch process was found to be similar to that of retail gasoline. The advantages of the synthetic fuel are that it contains no contaminants that would poison the fuel cell catalyst, is relatively benign to the environment, and could be transported in the existing fuel distribution system.

    Purpose: To assess QCT equivalent BMD of the lumbar spine in sagittal reformations of routine abdominal contrast-enhanced MDCT with simple PACS measurement tools and to apply this method to MDCT datasets for differentiating patients with and without osteoporotic vertebral fractures. Materials and methods: Eight postmenopausal women (65 {+-} 5years) underwent standard QCT to assess BMD of L1-L3. Afterwards routine abdominal contrast-enhanced MDCT images of these women were obtained and apparent BMD of L1-L3 was measured using the sagittal reformations. The MDCT-to-QCT conversion equation for BMD was calculated with linear regression analysis. The conversion equation was applied to vertebral BMD datasets (L1-L3) of 75 postmenopausal women (66 {+-} 4years). Seventeen of the 75 patients had osteoporotic vertebral fractures. Results: BMD values of contrast-enhanced MDCT were on average 56 mg/ml higher than those of standard QCT. A correlation coefficient of r = 0.94 (p < 0.05) was calculated for the BMD values of MDCT and standard QCT with the conversion equation BMD{sub QCT} = 0.69 x BMD{sub MDCT} - 11 mg/ml. Accordingly converted BMD values of patients with vertebral fractures were significantly lower than those of patients without vertebral fractures (69 mg/ml vs. 85 mg/ml; p < 0.05). Using ROC analysis to differentiate patients with and without vertebral fractures, AUC = 0.72 was obtained for converted BMD values (p < 0.05). Short- and long-term reproducibility errors for BMD measurements in the sagittal reformations amounted 2.09% and 7.70%, respectively. Conclusion: BMD measurements of the spine could be computed in sagittal reformations of routine abdominal contrast-enhanced MDCT with minimal technical and time effort. Using the conversion equation, the acquired BMD data could differentiate patients with and without osteoporotic vertebral fractures.

  5. Tales of two islands – Lessons for EU energy policy from electricity market reforms in Britain and Ireland

    International Nuclear Information System (INIS)

    Newbery, David

    2017-01-01

    Britain considers the energy-only EU Target Electricity Model (TEM) wanting in delivering the trilemma of reliability, sustainability and affordability and argues that a capacity auction with long-term contracts for new entrants is the least-cost solution compared to relying on expectations of future prices to deliver adequate generation and demand side response. The Energy Union argues against feed-in tariffs (FiTs) for renewables, pressing for premium FiTs (pFiTs), just as GB has abandoned PFiTs in favour of FiTs. This paper draws on the GB experience of Electricity Market Reform before and after the 2015 change of government, to highlight promising resolutions of the energy trilemma, and the problems that have arisen between the diagnosis of the problem and the delivery of solutions. It sets out the theory and practice of delivering capacity, energy and quality of supply, gives a brief history of GB electricity from the CEGB to its current unbundled, liberalized and privatized structure. That sheds light on the trilemma problem and discusses possible solutions. The island of Ireland Single Electricity Market reforms illustrate the problem and possible answer of how best to deliver quality of service with high intermittency. - Highlights: • The UK has introduced capacity payments and feed-in tariffs for renewables. • This contrasts with the energy-only target model and the Energy Union vision. • Transmission and distribution charges are critical in capacity auctions. • New flexibility services are needed for massive renewables penetration. • Britain and Ireland provide relevant evidence on addressing the energy trilemma.

    2013-01-01

    Energy consumption and efficiency emerged as the hottest topic in the context of China's sustainable development. Energy subsidies and “rebound effect” were closely related to this topic while few combinative studies on them with a focus on China. This paper employed a co-thinking approach, focusing on how the energy subsidies reform could mitigate the rebound effect in China, and how to achieve an “economic and environmental gains” that reduced pecuniary spending, improved the distorted energy market and reduced energy consumption simultaneously. Firstly, with price-gap approach we calculated the total energy subsidies scale of China in 2007, which amounted to582.0 billion CNY; then we detected and identified rebound effect of China energy consumption with the features. Furthermore, based on China 2007 monetary input–output table and energy flow analysis, we compiled a hybrid physical energy input and monetary output model (EIMO) to simulate the mitigation effect of subsidies reform. Results showed that removing energy subsidies would decrease ultimate demand of different economy sectors and reduce the accumulatively physical consumption of coal, oil, natural gas and electricity by 17.74, 13.47, 3.64 and 15.82 million tce, respectively. Finally we discussed relevant policy issues on China's energy subsidies reform in depth. - Highlights: ► Analyze the economic and environmental gains of fossil energy subsidies reform in China. ► Energy input and monetary output model was applied for analysis. ► Subsidies reform would help to reduce the rebound effect. ► The benefits of money saving, energy saving and CO 2 mitigation were achieved

    Industrial demand for neutrons constrains careful energy measurements. Elastic scattering of monoenergetic α -particles from neutron collision enables neutron energy measurement by calculating the amount of deviation from the position where collision takes place. The neutron numbers with specific energy is obtained by counting the number of α -particles in the corresponding location on the charged particle detector. Monte Carlo simulation and COMSOL Multiphysics5.2 are used to account for one-to-one collision of neutrons with α -particles.

    This article deals with the energy harvesting systems, especially the energy harvesting backpack, which appears as a convenient means for energy harvesting for mobile sensors power. Before starting the experiment, it was necessary to verify whether this energy will be sufficient to get acquainted with the human kinematics and analyze problematics itself. For this purpose there was used motion capture technology from Xsens. Measured data on the position of a particle moving man and back when walking, these data were then used for experimental realization of energy harvesting backpack and as input data to the simulation in Simulink, which brought us a comparison between theoretical assumptions and practical implementation. When measuring characteristics of energy harvesting system we have a problem with measurements on backpack solved when redoing of the hydraulic cylinder as a source of a suitable movement corresponding to the amplitude and frequency of human walk.

    The Fermilab Antiproton Accumulator has recently been used to produce Charmonium resonances (charm quark, anti-charm quark bound states) in proton-antiproton annihilations using an internal H 2 gas jet target. A measurement of the resonance mass and width may be obtained from a precise knowledge of the antiproton beam energy and energy spread. The beam energy is measured to an accuracy of 1 part in 10 4 in the range 6.3 Gev to 4.1 Gev by measuring the orbit length and revolution frequency of the beam. The beam momentum spread is measured to an accuracy of 10% by measuring the beam frequency spread and the parameter η = (P beam /F rev )·(dF rev /dP beam ). These two measurement techniques are described in this report

    In this paper the authors compare and contrast three powerful methods for experimentally measuring bond energies in polyatomic molecules. The methods are: radical kinetics; gas phase acidity cycles; and photoionization mass spectroscopy. The knowledge of the values of bond energies are a basic piece of information to a chemist. Chemical reactions involve the making and breaking of chemical bonds. It has been shown that comparable bonds in polyatomic molecules, compared to the same bonds in radicals, can be significantly different. These bond energies can be measured in terms of bond dissociation energies

    All measurements where conducted in the spring of 2007, except the Interpane panel. The solar cell panels have been evaluated by three performance indicators to assess the daylight quantity within the room and the systems ability to maintain view to the outside. In the study, we used two performance indicators to assess the daylight quantity within the room: 1. the daylight factor (overcast sky) 2. the relative work plane illuminance (clear sky condition) Overcast sky: In general, all panels provided less daylight than the recommended requirement in the Danish Building Regulation of 2% on the work plane. This will most likely result in additional need for electric lighting. However, larger window areas and more parts of the facade with clear unobstructed glass may be one solution. Clear sky: In general, all panels provided less interior light levels than the two reference systems in the back of the room. Almost all systems aloud more or less direct sunlight in the window perimeter through the clear openings and additional needs for some kind of shading device is to be expected. Some systems blocked a large portion of the light in the majority of the room, and additional electric light in this part of the room may be needed. Only one performance indicator where used to describe the quality of the panels. View: In general, all panels, except two, obstruct the view significantly and cause figure/background confusion for a view position close to the window and the discrepancies of colour judgements. Only two systems provided a fairly clear view to the outside without to much distortion of the view. (au)

    2005-10-01

    This document provides standard definitions of performance metrics and methods to determine them for the energy performance of building interior lighting systems. It can be used for existing buildings and for proposed buildings. The primary users for whom these documents are intended are building energy analysts and technicians who design, install, and operate data acquisition systems, and who analyze and report building energy performance data. Typical results from the use of this procedure are the monthly and annual energy used for lighting, energy savings from occupancy or daylighting controls, and the percent of the total building energy use that is used by the lighting system. The document is not specifically intended for retrofit applications. However, it does complement Measurement and Verification protocols that do not provide detailed performance metrics or measurement procedures.

    This study discusses how to quantify the energy savings related to the companies' aims to enhance their customers' energy efficiency which is one target in the Action Plan for Energy Services in the Energy Efficiency Agreement for the Industries. In Finland, a majority of the energy utilities have signed this action plan and are providing their customers services to improve their energy efficiency. Dissemination of information is the most widely used service to the customers and it is provided in a number of ways including printed material, annual energy report, and an internet tool to access and report hourly measurements. Some of the internet tools cover electricity, district heat and water. The focus of the study is in the evaluation of 'soft' measures; in other words, those measures given by energy utilities that principally rely on communication instruments. However, monitoring the impact of information and communication is far from easy. Carrying out a properly designed evaluation of programmes aiming on enhanced energy efficiency is difficult. Evaluation of the impact of a magazine article on energy efficiency is even more challenging, costly and therefore also rare. Distribution of information as measure to enhance energy efficiency is an important part of EU.s energy policy but what are the ways and even more so, are there ways to actually quantify these savings? There has been excessive work by the member states and research institutes to find a common and robust methodology within the EU to evaluate and quantify energy savings from technical measures. The ex-ante and ex-post results from these evaluations can however differ considerably, e.g. the expected energy savings from installing air to air heat pumps in Denmark did not deliver the expected energy savings. The problems with finding a common robust methodology become even more visible when the 'soft' measures are put under the evaluation loop. The &apos

    Measures of affordability and of fuel poverty are applied in practice to assess the affordability of energy services, for example, or of water or housing. The extensive body of literature on affordability measures has little overlap with the existing literature on poverty measurement. A comprehensive assessment of the response of affordability measures as a result of changes in the distribution of income or expenditure (the dynamic properties) is missing. This paper aims to fill this gap by providing a conceptual discussion on the ‘dynamics’ of both energy affordability measures and fuel poverty measures. Several types of measures are examined in a microsimulation framework. Our results indicate that some measures exhibit odd dynamic behavior. This includes measures used in practice, such as the low income/high cost measure and the double median of expenditure share indicator. Odd dynamic behavior causes the risk of drawing false policy recommendations from the measures. Thus, an appropriate response of affordability measures to changes in relevant variables is a prerequisite for defining meaningful measures that inform about affordability or deprivation in certain domains of consumption. - Highlights: • We investigate changes in fuel poverty measures as result from changes in income and expenditure. • More generally, we investigate dynamic behavior of affordability measures using microsimulation. • We propose axioms regarding dynamic behavior of affordability measures. • Some measures which are used in practice show unintuitive dynamic behavior. • Inappropriate dynamic behavior causes a risk of false policy implications.

  20. Main aspects of the planned reform of the Act on the Peaceful Uses of Atomic Energy and Protection against its Hazards (Atomic Energy Act)

    Lukes, R.

    1991-01-01

    There is no specific reason for planning a reform of the atomic energy law just now; the main idea is to keep the atomic energy law abreast with the developments made in the regime of protective laws pertaining to the sector of science and technology. A further aspect not to be neglected, however, is the nuclear power phase-out currently under debate, and a decision against the abandonment of nuclear power should be taken as an occasion to think about a nuclear law reform. The judiciary has been contributing to the development of nuclear law in the last years, and the decisions of the Federal Constitutional Court and of the Federal Administrative Court have not only set the corner flags for the future development of the nuclear law, but have given concrete shape by final settlement of cases of divergence of judicial decisions, to the protective intents of the law and to the subject-related purposes. Thus the judiciary has been taking into account the idea prevailing today, namely that the scope of duties of the Federal Government certainly includes the task of protecting the citizens against the hazards of technology in general, and of novel technologies in particular, and the task of avoiding hazards. So the main line of orientation to be pursued is to draw level with protective regulations established in other fields of law, and to make the Atomic Energy Act a modern instrument of protection by the law.

  1. The reform of energy subsidies for the enhancement of marine sustainability: An empirical analysis of energy subsidies worldwide and an in-depth case study of South Korea's energy subsidy policies

    Science.gov (United States)

    Shim, Jae Hyun

    This dissertation seeks to raise awareness about harmful effects of fossil fuel and nuclear energy subsidies that have blocked transition from conventional energy to a decarbonized, renewable energy system. Today, humans face daunting challenges in the form of global warming, which results mainly from the burning of fossil fuels. To avoid catastrophe, the transition to a renewable energy regime should be an urgent priority; however, the reality is that the progress of renewable energy is very slow due to the various political and economic factors when compared to conventional energy resources. A chief factor is that the energy subsidy for fossil fuel and nuclear energy obstructs the "level playing field" for renewable energy. Energy subsidies for conventional energy can be understood in the context of the commodification paradigm, which regards nature as an object of conquest and supports the principle of more is better. Although fossil fuel energy damages the environment, economy, and social equity, all countries subsidize such energy, no matter the country's state of development. This holds true as much in the U.S. and the EU as in China, India and South Korea. The oceans, which cover 71% of the earth, are threatened by the activities of conventional energy, which are underpinned by subsidies. These subsidies have contributed to the destruction of the marine ecosystem through increased GHG emissions like CO2 and NOx which cause a sea temperature increase and coral bleaching. Subsidies also significantly affect fishery overexploitation, oil pollution, and thermal pollution. In-depth empirical analysis of South Korea showed how fossil fuel and nuclear energy activities have threatened marine sustainability through thermal pollution, algae bloom (red tides), overexploitation, and oil-related marine pollution. Reforming subsidies of fossil fuel and nuclear energy should be a global priority because of imminent of global warming. As strategies for energy subsidy

    During anaerobic digestion, organic matter is converted to carbon dioxide and methane, and organic nitrogen is converted to ammonia. Generally, ammonia is recycled as a fertilizer or removed via nitrification–denitrification in treatment systems; alternatively it could be recovered and catalytically converted to hydrogen, thus supplying additional fuel. To provide a basis for further investigation, a theoretical energy balance for a model system that incorporates anaerobic digestion, ammonia separation and recovery, and conversion of the ammonia to hydrogen is reported. The model Anaerobic Digestion-Bioammonia to Hydrogen (ADBH) system energy demands including heating, pumping, mixing, and ammonia reforming were subtracted from the total energy output from methane and hydrogen to create an overall energy balance. The energy balance was examined for the ADBH system operating with a fixed feedstock loading rate with C:N ratios (gC/gN) ranging from 136 to 3 which imposed corresponding total ammonia nitrogen (TAN) concentrations of 20–10,000 mg/L. Normalizing total energy potential to the methane potential alone indicated that at a C:N ratio of 17, the energy output was greater for the ADBH system than from anaerobic digestion generating only methane. Decreasing the C:N ratio increased the methane content of the biogas comprising primarily methane to >80% and increased the ammonia stripping energy demand. The system required 23–34% of the total energy generated as parasitic losses with no energy integration, but when internally produced heat and pressure differentials were recovered, parasitic losses were reduced to between 8 and 17%. -- Highlights: •Modeled an integrated Anaerobic Digestion-Bioammonia to Hydrogen (ADBH) system. •Demonstrated positive net energy produced over a range of conditions by ADBH. •Demonstrated significant advantages of dual fuel recovery for energy gain by >20%. •Suggested system design considerations for energy recovery with

    2015-01-01

    Since the 1992 Earth Summit in Rio and the negotiation of the United Nations Framework Convention on Climate Change (UNFCCC), the European Union has consistently been at the forefront of global action to combat climate change, leading the world to a low-carbon economy. The EU has set itself greenhouse gas emission targets designed to produce an almost carbon-free economy by 2050 in order to make a major contribution to limiting the global temperature increase by the end of the century to 2 deg. C, compared to the pre-industrial average. As an interim step on the way to 2050, EU leaders in March 2007 set a number of ambitious climate and energy targets known as the '20-20-20 targets by 2020' or the 3 x 20 policy. In this, the EU committed to: - A 20% reduction in EU greenhouse gas emissions from 1990 levels; - Raising the share of EU energy consumption produced from renewable resources to 20%; and - A 20% improvement in the EU's energy efficiency. This 3 x 20 package is a part of a wider European energy strategy that aims at enhancing: - Sustainability; - Competitiveness and affordability; and - Security of supply. The EU energy and climate package has attracted criticism in the last few years, as each day brought more evidence that the policy measures had numerous unexpected, or unintended impacts on the energy markets and industry: an excess of intermittent sources of electricity causing disruption for grid operators, surplus electricity resulting in a price collapse of the wholesale electricity market, electricity price increase at retail level, exit of gas from the fuels for power generation and the advent of coal as an electricity price-setter... At the same time, it has also become evident that EU policy has failed to solve the existing EU energy imbalances in general. Ironically, after years of huge investments aimed at achieving the ambitious policy targets, a number of the objectives still seem to be a long way away. Indeed some may not even

    This paper analyzes the evolution of productivity of the electricity distribution companies in Peru, to assess whether reforms have improved the efficiency in this sector. The paper also identifies potential sources of productivity changes, based on market restructuring the electricity sector and changes in property. To do this, we rely on a set of data for 14 distribution companies, for the period 1996-2006. Our analysis suggests that improvements in the efficiency and productivity of electricity distribution in Peru have occurred, and that there is a relationship between the restructuring of distribution sector and the enhancement of productivity.

    Linac4 is a 160 MeV normal-conducting linear accelerator for negative Hydrogen ions (H−), which will replace the 50 MeV proton Linac (Linac2) as linear injector for the CERN accelerators. The low energy part, comprising a 45 keV Low Energy Beam Transport system (LEBT), a 3 MeV Radiofrequency Quadrupole (RFQ) and a Medium Energy Beam Transport (MEBT) is being assembled in a dedicated test stand for pre-commissioning with a proton beam. During 2011 extensive measurements were done after the source and after the LEBT with the aim of preparing the RFQ commissioning and validating the simulation tools, indispensable for future source upgrades. The measurements have been thoroughly simulated with a multi-particle code, including 2D magnetic field maps, error studies, steering studies and the generation of beam distribution from measurements. Emittance, acceptance and transmission measurements will be presented and compared to the results of the simulations.

    2014-01-01

    Highlights: • A novel framework to characterize energy efficiency measures is proposed. • It allows a greater knowledge sharing, facilitating the adoption of the best measures. • It supports policy-makers in developing drivers for industrial energy efficiency. - Abstract: The need to increase the diffusion of energy efficiency measures (EEMs) is of crucial importance to achieve a consistent reduction of energy consumption and green house gases (GHG) emissions. A clear comprehension of the characteristics of such EEMs could assist in gathering and capitalizing all the information needed by industrial firms in selecting and adopting technologies, as well as by policy-makers in designing appropriate policies for their diffusion. Therefore, in this study, starting from a literature review of the studies analyzing the attributes of EEMs, we aim at providing an innovative and comprehensive framework to characterize such measures, based on 17 attributes grouped according to six categories, such as: economic, energy, environmental, production-related, implementation-related and the possible interaction with other systems. We applied this scheme to an extensive range of EEMs in cross-cutting technologies, i.e. motors, compressed air, lighting and HVAC systems. The analysis provides a relevant contribution firstly to the structuring and the sharing of knowledge on EEMs and hence to the comprehension of the barriers currently hindering their adoption; secondly, it provides a structured basis for the analysis of the drivers that policy-makers should develop in order to promote industrial energy efficiency

  12. The rise and fall of French Ecological Tax Reform: social acceptability versus political feasibility in the energy tax implementation process

    International Nuclear Information System (INIS)

    Deroubaix, Jose-Frederic; Leveque, Francois

    2006-01-01

    The French government has a 10-year history of negotiations with industry, resulting in voluntary agreements on energy consumption. When implemented, these voluntary agreements produced very few results in terms of global reduction of greenhouse emissions (Politiques et Management Public 11(4) (1993) 47), hence the idea of an energy tax became increasingly attractive for many French decision-makers. Ecological/Environmental Tax Reform (ETR) should have been one of the major political decisions and successes of the past leftwing coalition government. Instead it became one of its major failures as the Constitutional Court decided to terminate the energy tax project in December 2000. Through insights gleaned from focus groups and interviews with business-people and decision-makers, an attempt is made to understand the failure of the energy tax project. Firstly, decision-makers lacked crucial information about public and business opinions and secondly, there were conflicts between the relevant administrations. The fuel revolts of 2000 ended any hope of resolving the conflicts and implementing ETR, which was ultimately found unconstitutional. This paper examines the political controversies raised by the ETR project and the reasons for its eventual collapse, in the hope of contributing new understanding to the body of knowledge on the political difficulties of introducing environmental policy instruments.

  13. Measuring Income and Projecting Energy Use

    International Nuclear Information System (INIS)

    Pitcher, Hugh M.

    2009-01-01

    Energy is a key requirement for a healthy, productive life and a major driver of the emissions leading to an increasingly warm planet. The implications of a doubling and redoubling of per capita incomes over the remainder of this century for energy use are a critical input into understanding the magnitude of the carbon management problem. A substantial controversy about how the Special Report on Emssions Scenarios (SRES) measured income and the potential implications of how income was measured for long term levels of energy use is revisited again in the McKibbin, Pearce and Stegman article appearing elsewhere in this issue. The recent release of a new set of purchasing power estimates of national income, and the preparations for creating new scenarios to support the IPCC's fifth assessment highlight the importance of the issues which have arisen surrounding income and energy use. Comparing the 1993 and 2005 ICP results on Purchasing Power Parity (PPP) based measures of income reveals that not only do the 2005 ICP estimates share the same issue of common growth rates for real income as measured by PPP and US $, but the lack of coherence in the estimates of PPP incomes, especially for developing countries raises yet another obstacle to resolving the best way to measure income. Further, the common use of an income term to mediate energy demand (as in the Kaya identity) obscures an underlying reality about per capita energy demands, leading to unreasonable estimates of the impact of changing income measures and of the recent high GDP growth rates in India and China. Significant new research is required to create both a reasonable set of GDP growth rates and long term levels of energy use.

    2017-11-01

    From the perspective of energy supply-side reform, this paper, by conducting an empirical study on foreign trade enterprises, conducts a research on the cross-role effect of optimizing the resources allocation and enhancing the energy efficiency. Methodologically, this paper creatively introduces the HILE's probabilistic structured property into Granger causality test analysis, forming an HILE-Granger (H-G) model, so as to empirically estimate both the short-term and long-term causal relationship effects between the energy efficiency and resources allocation. Conclusion is drawn that optimization of resources allocation is positively proportional with the energy efficiency enhancement. This paper is to provide a decision-making reference for the supply side reform strategy of foreign trade enterprises under the background of green energy economy.

  15. Fossil fuel subsidy reform: lessons from the Indonesian case

    International Nuclear Information System (INIS)

    Savatic, Filip

    2016-10-01

    Global assessments of consumption and the Indonesian case show the relevance of non-household consumers of subsidized energy products. As shown in this study, understanding in more nuance how reforms affect them has the potential to improve the reforms that will be developed by policy-makers worldwide. Further study can reinforce the many benefits of successful reform for the countries and societies slowly turning away from these policies of the past. Estimates regarding the amount of public funds utilized to subsidize the production or consumption of fossil fuels are staggering. For 2011, they range from $83 billion in OECD member states, to nearly $4.1 trillion worldwide if environmental externalities are considered. Numerous studies have demonstrated that subsidies repress economic growth, undermine energy sector investment, increase public debt, benefit wealthy citizens over the poor, instigate a rise in illicit activities, and engender greater global and local pollution. The negative effects of fossil fuel subsidies have led numerous governments to reform their energy policies. There has also been a growing international consensus in favor of reform. While the components of successful reform programs have been identified through past case studies, the nature of reforms adopted by several governments that target non-households have not been systematically examined. Since the late 1990s, the Indonesian government has implemented numerous reforms of its fossil fuel subsidies, including measures targeting household as well as non-household energy consumption. In doing so, it has incurred significant fiscal savings. However, an innovative budgetary analysis reveals that households receive a minority, and a declining share, of fossil fuel subsidy funds. This is the case despite the fact that subsidies were implemented to ensure poor households have access to cheap energy. These findings demonstrate the need to consider non-household sectors in the design of fossil

    2016-01-01

    Highlights: • A case study of implementation of eco energy technologies in municipal transport. • The “ready to use” methods are presented. • The “niche” ways of increasing efficiency, e.g. “intelligent heating”. • Novel multi way measurement method using GPS localization system. • Confirmation of the results by means of research and experimental measurement. - Abstract: Nowadays the issue of electric energy saving in public transport is becoming a key area of interest, which is connected both with a growth of environmental awareness in the society and an increase in the prices of fuel and electricity. That is why the reduction of energy consumption by increasing electrified urban transport, such as trams, trolleybuses, light rail and underground is becoming an increasingly important issue. Energy recovery during braking is possible in all modern electric vehicles, but in many cases this possibility is not fully taken advantage of, inter alia, because of an inadequate power supply structure. The aim of this article is to present practical examples of implementation of eco-friendly solutions in urban municipal transport. The article shows a thorough analysis of braking energy dispatch in the urban traction power supply system, which was based on extensive measurement research conducted in Gdynia trolleybus network. The authors applied multi way measurement method using Global Positioning System. The optimal conditions for implementation of several methods of energy recovery (storage energy systems, reconfiguration of supply system, using auxiliaries) have been shown. Great emphasis has been put on the confirmation of the results by means of research and experimental measurement.

  18. The ambiguities of performance-based governance reforms in Italy: Reviving the fortunes of evaluation and performance measurement.

    Marra, Mita

    2018-08-01

    Over the past two decades, Italy's administrative reforms have institutionalized evaluation to improve program effectiveness, staff productivity, and results-driven accountability against waste and corruption. Across ministries, regional governments, universities, schools and environmental protection agencies, seemingly unexpected consequences have emerged out of the implementation of performance measurement and evaluation regimes within public organizations. Formal compliance to legally binding evaluation procedures, judicially-sanctioned managerial accountability and lack of cross-agency coordination coupled with long-standing cultural separations among evaluators are some of the ambiguities associated with a performance-based governance system within Italian public administration. Building upon the 'new governane theory,' and qualitative fieldwork, I explore the political consequences of evaluation and performance measurement for possible improvements. From a normative perspective, greater integration between program evaluation and performance measurement can support organizational learning and democratic accountability both at the central and local level.

    Ground-based indirect measurements have shown that the cosmic-ray allparticle spectrum extends many orders of magnitude beyond the energy thought possible for supernova acceleration. Our balloon-borne Cosmic Ray Energetics And Mass (CREAM) experiment is capable of extending direct measurements of cosmic-rays to the supernova energy scale of 1015 eV in a series of Ultra Long Duration Balloon (ULDB) flights. Identification of Z = 1 - 26 particles will be made with a timing-based charge detector and a pixelated silicon charge detector. Energy measurements will be made with a transition radiation detector and a tungsten/scintillating fiber calorimeter. The instrument has been tested with various particles in accelerated beams at the CERN SPS. The first flight is planned to be launched from Antarctica in December 2004.

    This document presents the most cost effective Energy Savings Measure Packages (ESMP) for existing mixed-fuel and all electric homes to achieve 15% and 30% savings for each BetterBuildings grantee location across the United States. These packages are optimized for minimum cost to homeowners for source energy savings given the local climate and prevalent building characteristics (i.e. foundation types). Maximum cost savings are typically found between 30% and 50% energy savings over the reference home; this typically amounts to $300 - $700/year.

    Urban, A.

    1981-01-01

    This paper summarizes ion measurements in the energy range 0.1 to 30 keV observed during the campaigns 'Substorm Phenomena' and 'Porcupine'. For a clear survey of the physical processes during extraordinary events, sometimes ion measurements of higher energies are also taken into account. Generally, the pitch angle distributions were isotropic during all flights except some remarkable events. In general the ion and electron flux intensities correlated, but sometimes revealed a spectral anti-correlation. Acceleration of the ions by an electrostatic field aligned parallel to the magnetic field could be identified accompanied by intense electron precipitation. On the other hand deceleration of the ions was observed in other field-aligned current sheets which are indicated by the electron and magnetic field measurements. Temporal successive monoenergetic ion variations pointed to energy dispersion and to the location of the source region at 9 Rsub(E). Furthermore, ion fluxes higher than those of the electrons were measured at pitch angles parallel to the magnetic field. The integral down-going number and energy flux of the ions contributed to the total particle or energy influx between 65% and less than 7% and did not clearly characterize the geophysical launch conditions or auroral activities.

    The term of the energy transition will not be translated as it travels around the world. He points to the urgency of the conversion of the energy supply for electricity, heat and mobility through renewable energies. Faster than many had expected the energy revolution has reached a pace of expansion, especially in the electricity sector, which many did not expect. However, it is not a voluntary measure, but is forced by the proneness of unsustainable production methods and lifestyles. It is also not a foregone conclusion. The many new initiatives, policies and programs are in competition with an old, fossil and nuclear energy system. From the hurdles that have already been taken in this race, the pace of expansion, innovation as well as the necessary reforms and diverse challenges of the energy transition, this book is dealing. [German] Der Begriff der Energiewende wird bei seinem Lauf um die Welt nicht uebersetzt. Er weist auf die Dringlichkeit der Umstellung der Energieversorgung bei Strom, Waerme und Mobilitaet durch erneuerbare Energien hin. Schneller als von vielen erwartet hat die Energiewende vor allem im Strombereich ein Ausbautempo erreicht, mit dem viele nicht gerechnet hatten. Sie ist allerdings keine freiwillige Massnahme, sondern wird durch die Krisenhaftigkeit von nicht nachhaltigen Produktions- und Lebensweisen erzwungen. Sie ist auch kein Selbstlaeufer. Die vielfaeltigen neuen Initiativen, Massnahmen und Programme befinden sich im Wettbewerb mit einem alten, fossilen und nuklearen Energiesystem. Von den Huerden, die in diesem Wettlauf bereits genommen wurden, vom Tempo des Ausbaus, von Innovationen sowie von den notwendigen Reformen und vielfaeltigen Herausforderungen der Energiewende handelt dieses Buch.

Power companies are placing emphasis on the remote accessibility of measurement data at customer sites and on a greater variety of rates. Enermet, a member of the IVO Group, is a frontrunner in this business area, investing 8 % of its turnover in product development

    We argue that the internal energy E=(H) of a macroscopic system in thermal equilibrium must increase, if we measure an observable A which does not commute with the Hamiltonian H. We derive an expression for calculating a lower bound for this increase in E. We then generalize the above result, and show that under certain conditions the expectation value (C) of an observable C should increase by the measurement of another observable A, if A and C do not commute.

    We review the relationship between energy efficiency improvement measures and productivity in industry. We review over 70 industrial case studies from widely available published databases, followed by an analysis of the representation of productivity benefits in energy modeling. We propose a method to include productivity benefits in the economic assessment of the potential for energy efficiency improvement. The case-study review suggests that energy efficiency investments can provide a significant boost to overall productivity within industry. If this relationship holds, the description of energy-efficient technologies as opportunities for larger productivity improvements has significant implications for conventional economic assessments. The paper explores the implications this change in perspective on the evaluation of energy-efficient technologies for a study of the iron and steel industry in the US. This examination shows that including productivity benefits explicitly in the modeling parameters would double the cost-effective potential for energy efficiency improvement, compared to an analysis excluding those benefits. We provide suggestions for future research in this important area.

    This report represents the national case study of Norway for the IEE-project {sup M}onitoring of EU and national energy efficiency targets (ODYSSEE-MURE 2010)'. The Norwegian part of the project is co-funded by Enova. The report presents the recent energy efficiency trends in Norway on the basis of indicators extracted from the ODYSSEE database. The database contains information on energy use in a detailed level of the industry, transport, household and service sectors and other energy use. lt also contains information on energy drivers like heated square meters in the households and services sectors, transported passenger-km and ton-km of gods, value added, production index, production volumes etc. Final energy consumption has increased from 195 TWh in 1990 lo 229 TWh in 2010 The last ten years the energy consumption has varied between 212I Wh (2009) and 229 TWh (2010) with an annual average of 221TfUh. The sector using most energy is the industry, but the share has decreased from 40 % in 1990 to 31 % in 2010. From 1990 to 2010 the growth rate has been highest in the transport sector. Half of the energy end-use was electricity in 20,10, 42 % was fossil fuels and 6 % was biomass. The electricity use has an annual increase of 0.8 % since 1990, but the last decade the annual increase is reduced to 0.14 %. The consumption of oil products has decreased in stationary end-use (heating) and increased in the transport sector. In ODYSSEE, an aggregate bottom-up energy efficiency index, ODEX, is calculated. This energy efficiency index aggregates the trends in the detailed bottom-up indicators in one single indicator. This ODEX has improved by 26 o/o from 1990 to 2010 or by 1.3 o/o per year. This means that energy efficiency policies and measures implemented since 1990 have contributed to a decrease in the energy use of 2010 of approximately 59 TWh. (Author)

    These are turbulent times for the Dutch energy sector. The peace did not return when the Unbundling Act was implemented. The privatization of Nuon and Essent caused quite a stir. In the opinion of the author part of this stir was unjustified. It was the logical consequence of the liberalization of the energy markets that started 15 years ago. The soap does not end with the sale of the energy companies. The establishment of the public grid companies and finding a destination for the returns of the sales are new issues of conflict that emerge. [nl

    2002-01-01

    A new approach to energy loss measurements is proposed. In the same experiment electronic stopping force (power) in gold, nickel, carbon, polycarbonate and Havar for sup 4 sup 0 Ar, sup 2 sup 8 Si, sup 1 sup 6 O, sup 4 He and sup 1 H ions in the energy range 0.12-11 MeV/u has been measured. In this paper we give the full results for gold, nickel, and carbon and for sup 4 sup 0 Ar, sup 1 sup 6 O, sup 4 He and sup 1 H ions. Good agreement of the measured stopping force values for light ions with literature data is interpreted as the positive test of the experimental technique. The same technique used with heavy ions yields agreement with the published data only for energies above 1 MeV/u. At lower energies we observe progressively increasing discrepancy. This discrepancy is removed completely as soon as we neglect pulse height defect compensation. This observation makes us believe that the majority of the published results as well as semi-empirical calculations based on them (like the popular SRIM) may be in er...

    The ground-state dissociation energy, D0(S0), of isolated intermolecular complexes in the gas phase is a fundamental measure of the interaction strength between the molecules. We have developed a three-laser, triply resonant pump-dump-probe technique to measure dissociation energies of jet-cooled M•S complexes, where M is an aromatic chromophore and S is a closed-shell 'solvent' molecule. Stimulated emission pumping (SEP) via the S0→S1 electronic transition is used to precisely 'warm' the complex by populating high vibrational levels v" of the S0 state. If the deposited energy E(v") is less than D0(S0), the complex remains intact, and is then mass- and isomer-selectively detected by resonant two-photon ionization (R2PI) with a third (probe) laser. If the pumped level is above D0(S0), the hot complex dissociates and the probe signal disappears. Combining the fluorescence or SEP spectrum of the cold complex with the SEP breakoff of the hot complex brackets D0(S0). The UV chromophores 1-naphthol and carbazole were employed; these bind either dispersively via the aromatic rings, or form a hydrogen bond via the -OH or -NH group. Dissociation energies have been measured for dispersively bound complexes with noble gases (Ne, Kr, Ar, Xe), diatomics (N2, CO), alkanes (methane to n-butane), cycloalkanes (cyclopropane to cycloheptane), and unsaturated compounds (ethene, benzene). Hydrogen-bond dissociation energies have been measured for H2O, D2O, methanol, ethanol, ethers (oxirane, oxetane), NH3 and ND3.

    Climate change, in particular rainfall variability, affects rain-dependent agriculture in Africa. The resulting food shortages, in combination with rising population and lack of access to electricity needed for development, require the governments and people of Africa to consider renewable energy sources. One example that has high potential in Africa is solar energy. Many African governments have begun discussions about renewable energy but tangible results have yet to materialize. This research contributes to the governmental efforts by presenting the solar electricity potentials for some African cities. Using photovoltaic geographical information system (PVGIS) data, it is clear that there is enough electricity for urban and rural dwellers if there is political will and if the solar panels are mounted at the suggested optimal angles ranging from 8-34 . The solar irradiation at all sites was higher than the typical daily domestic load requirement of 2324 Wh/m 2 in urban and rural areas. We provide a strong rationale for political will, collaboration and transparent energy policies that will ensure that life is enhanced through the use of environmentally-friendly renewable energy technologies such as solar power.

    The paper discusses selected problems related to application of energy harvesting (that is, generating electricity from surplus energy present in the environment) to supply autonomous ultra-low-power measurement systems applicable in high voltage engineering. As a practical example of such implementation a laboratory model of a remote temperature sensor is presented, which is self-powered by heat generated in a current-carrying busbar in HV- switchgear. Presented system exploits a thermoelectric harvester based on a passively cooled Peltier module supplying micro-power low-voltage dc-dc converter driving energy-efficient temperature sensor, microcontroller and a fibre-optic transmitter. Performance of the model in laboratory simulated conditions are presented and discussed. (paper)

  14. Energy intensity ratios as net energy measures of United States energy production and expenditures

    International Nuclear Information System (INIS)

    2010-01-01

    In this letter I compare two measures of energy quality, energy return on energy invested (EROI) and energy intensity ratio (EIR) for the fossil fuel consumption and production of the United States. All other characteristics being equal, a fuel or energy system with a higher EROI or EIR is of better quality because more energy is provided to society. I define and calculate the EIR for oil, natural gas, coal, and electricity as measures of the energy intensity (units of energy divided by money) of the energy resource relative to the energy intensity of the overall economy. EIR measures based upon various unit prices for energy (e.g. $/Btu of a barrel of oil) as well as total expenditures on energy supplies (e.g. total dollars spent on petroleum) indicate net energy at different points in the supply chain of the overall energy system. The results indicate that EIR is an easily calculated and effective proxy for EROI for US oil, gas, coal, and electricity. The EIR correlates well with previous EROI calculations, but adds additional information on energy resource quality within the supply chain. Furthermore, the EIR and EROI of oil and gas as well as coal were all in decline for two time periods within the last 40 years, and both time periods preceded economic recessions.

    The furnace waste heat of a company’s existing 4 × 100t ultra-high-power electric arc furnaces is not used and discharged directly of the situation has been unable to meet the national energy-saving emission reduction requirements, and also affected their own competitiveness and sustainable development. In order to make full use of the waste heat of the electric arc furnace, this paper presents an the energy-saving transformation program of using the new heat pipe boiler on the existing ultra-high-power electric arc furnaces for recovering the waste heat of flue gas. The results show that after the implementation of the project can save energy equivalent to 42,349 tons of standard coal. The flue gas waste heat is fully utilized and dust emission concentration is accorded with the standard of Chinese invironmental protection, which have achieved good results.

  16. Iran's sustainable development and the need to a reform in energy consumption policy

    2007-01-01

    The Islamic Republic of Iran has always paid a lot of attention to the concept of sustainable development since the article fifty of its constitution forbids any activity that results in pollution or in the irremediable destruction of the environment. According to the International Atomic Energy Agency (IAEA), the consumption of electricity is practically synonymous with modern life in the industrialized world. From this point of view, the optimization of production and consumption of energy are among the main strategies in both developed and developing countries. Considering a report published by the World Bank in 2004, over 96% of electricity production in Iran in 2001 came from fossil sources (74.9% from gas and 21.2% from oil) and the insignificant remaining part (3.9%) was based on hydroelectric sources. Although Iran's export of crude oil currently runs about 2.3 million barrels per day, total refining capacity of the country (1.5 million barrels per day) is insufficient to meet the country's domestic need. If the current rate of oil and gasoline consumption continues in Iran, the country will lose its oil export revenues by 2015. Combustion of fossil fuels in Iran produces large amounts of CO 2 (the biggest contributor to global warming), noxious gases, and many toxic pollutants. Analysis of carbon dioxide production in Iran clearly confirms the necessity of the use of emission-free alternative energy resources such as hydroelectric and nuclear power. It should be also noted that Iran's rich fossil resources can be used in many industrial fields such as petrochemistry, while currently the only practical application of uranium is energy production. It can be concluded that due to Iran's rapidly increasing energy demand, optimal use of fossil resources and using combination of proper resources such as hydro-nuclear energy as effective alternatives seem to be inevitable in the upcoming years of 21. century

    Purpose: To compare different methods measuring abdominal aortic aneurysm (AAA) maximal diameter (Dmax) and its progression on multidetector computed tomography (MDCT) scan. Materials and Methods: Forty AAA patients with two MDCT scans acquired at different times (baseline and follow-up) were included. Three observers measured AAA diameters by seven different methods: on axial images (anteroposterior, transverse, maximal, and short-axis views) and on multiplanar reformation (MPR) images (coronal, sagittal, and orthogonal views). Diameter measurement and progression were compared over time for the seven methods. Reproducibility of measurement methods was assessed by intraclass correlation coefficient (ICC) and Bland–Altman analysis. Results: Dmax, as measured on axial slices at baseline and follow-up (FU) MDCTs, was greater than that measured using the orthogonal method (p = 0.046 for baseline and 0.028 for FU), whereas Dmax measured with the orthogonal method was greater those using all other measurement methods (p-value range: <0.0001–0.03) but anteroposterior diameter (p = 0.18 baseline and 0.10 FU). The greatest interobserver ICCs were obtained for the orthogonal and transverse methods (0.972) at baseline and for the orthogonal and sagittal MPR images at FU (0.973 and 0.977). Interobserver ICC of the orthogonal method to document AAA progression was greater (ICC = 0.833) than measurements taken on axial images (ICC = 0.662–0.780) and single-plane MPR images (0.772–0.817). Conclusion: AAA Dmax measured on MDCT axial slices overestimates aneurysm size. Diameter as measured by the orthogonal method is more reproducible, especially to document AAA progression.

    The local electron energy flux produced by magnetic fluctuations has been measured directly in the MST reversed field pinch (over the radial range r/a > 0.75). The flux, produced by electrons traveling parallel to a fluctuating magnetic field, is obtained from correlation between the fluctuations in the parallel heat flux and the radial magnetic field. The fluctuation induced flux is large (100 kW/cm 2 ) in the ''core'' (r/a 2 ) in the edge

    2007-01-01

    We suggest a new method for the determination of the detector relative energy resolution and its uncertainty based on spline approximation of experimental spectra and a statistical bootstrapping procedure. The proposed method is applied to the spectra obtained with NaI(Tl) scintillating detectors and 137 Cs sources. The spectrum histogram with background subtracted channel-by-channel is modeled by cubic spline approximation. The relative energy resolution (which is also known as pulse height resolution and energy resolution), defined as the full-width at half-maximum (FWHM) divided by the value of peak centroid, is calculated using the intercepts of the spline curve with the line of the half peak height. The value of the peak height is determined as the point where the value of the derivative goes to zero. The residuals, which are normalized over the square root of counts in a given bin (y-coordinate), obey the standard Gaussian distribution. The values of these residuals are randomly re-assigned to a different set of y-coordinates where a new 'pseudo-experimental' data set is obtained after 'de-normalization' of the old values. For this new data set a new spline approximation is found and the whole procedure is repeated several hundred times, until the standard deviation of relative energy resolution becomes stabilized. The standard deviation of relative energy resolutions calculated for each 'pseudo-experimental' data set (bootstrap uncertainty) is considered to be an estimate for relative energy resolution uncertainty. It is also shown that the relative bootstrap uncertainty is proportional to, and generally only two to three times bigger than, 1/√(N tot ), which is the relative statistical count uncertainty (N tot is the total number of counts under the peak). The newly suggested method is also applicable to other radiation and particle detectors, not only for relative energy resolution, but also for any of the other parameters in a measured spectrum, like

    Using the magnetic spectrometer SPES I at SATURNE, energy-loss measurements have been performed for projectiles of 40 Ar (401 MeV/u), 36 P (362 MeV/u), 15 N (149 MeV/u), 11 Li (131 MeV/u) and 8 Li, 9 Li (130 MeV/u) in carbon, aluminum and lead targets. The experimental results are compared to calculations based on a modified relativistic Bethe formula and to a semi-empirical formula using a Z 2 scaling law for the stopping power and an effective charge parametrization for the heavy ions.

  1. Measuring the impact of marginal tax rate reform on the revenue base of South Africa using a microsimulation tax model

    Directory of Open Access Journals (Sweden)

    Yolande Jordaan

    2015-08-01

    Full Text Available This paper is primarily concerned with the revenue and tax efficiency effects of adjustments to marginal tax rates on individual income as an instrument of possible tax reform. The hypothesis is that changes to marginal rates affect not only the revenue base, but also tax efficiency and the optimum level of taxes that supports economic growth. Using an optimal revenue-maximising rate (based on Laffer analysis, the elasticity of taxable income is derived with respect to marginal tax rates for each taxable-income category. These elasticities are then used to quantify the impact of changes in marginal rates on the revenue base and tax efficiency using a microsimulation (MS tax model. In this first paper on the research results, much attention is paid to the structure of the model and the way in which the database has been compiled. The model allows for the dissemination of individual taxpayers by income groups, gender, educational level, age group, etc. Simulations include a scenario with higher marginal rates which is also more progressive (as in the 1998/1999 fiscal year, in which case tax revenue increases but the increase is overshadowed by a more than proportional decrease in tax efficiency as measured by its deadweight loss. On the other hand, a lowering of marginal rates (to bring South Africa’s marginal rates more in line with those of its peers improves tax efficiency but also results in a substantial revenue loss. The estimated optimal individual tax to gross domestic product (GDP ratio in order to maximise economic growth (6.7 per cent shows a strong response to changes in marginal rates, and the results from this research indicate that a lowering of marginal rates would also move the actual ratio closer to its optimum level. Thus, the trade-off between revenue collected and tax efficiency should be carefully monitored when personal income tax reform is being considered.

    It is crucial to predict the human energy expenditure in any sports activity and health science application accurately to investigate the impact of the activity. However, measurement of the real energy expenditure is not a trivial task and involves complex steps. The objective of this work is to improve the performance of existing estimation models of energy expenditure by using machine learning algorithms and several data from different sensors and provide this estimation service in a cloud-based platform. In this study, we used input data such as breathe rate, and hearth rate from three sensors. Inputs are received from a web form and sent to the web service which applies a regression model on Azure cloud platform. During the experiments, we assessed several machine learning models based on regression methods. Our experimental results showed that our novel model which applies Boosted Decision Tree Regression in conjunction with the median aggregation technique provides the best result among other five regression algorithms. This cloud-based energy expenditure system which uses a web service showed that cloud computing technology is a great opportunity to develop estimation systems and the new model which applies Boosted Decision Tree Regression with the median aggregation provides remarkable results.

  3. 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.

  4. FLUIDIZED BED STEAM REFORMING MINERALIZATION FOR HIGH ORGANIC AND NITRATE WASTE STREAMS FOR THE GLOBAL NUCLEAR ENERGY PARTNERSHIP

    Energy Technology Data Exchange (ETDEWEB)

    Jantzen, C; Michael Williams, M

    2008-01-11

    Waste streams that may be generated by the Global Nuclear Energy Partnership (GNEP) Advanced Energy Initiative may contain significant quantities of organics (0-53 wt%) and/or nitrates (0-56 wt%). Decomposition of high nitrate streams requires reducing conditions, e.g. organic additives such as sugar or coal, to reduce the NO{sub x} in the off-gas to N{sub 2} to meet the Clean Air Act (CAA) standards during processing. Thus, organics will be present during waste form stabilization regardless of which GNEP processes are chosen, e.g. organics in the feed or organics for nitrate destruction. High organic containing wastes cannot be stabilized with the existing HLW Best Developed Available Technology (BDAT) which is HLW vitrification (HLVIT) unless the organics are removed by preprocessing. Alternative waste stabilization processes such as Fluidized Bed Steam Reforming (FBSR) operate at moderate temperatures (650-750 C) compared to vitrification (1150-1300 C). FBSR converts organics to CAA compliant gases, creates no secondary liquid waste streams, and creates a stable mineral waste form that is as durable as glass. For application to the high Cs-137 and Sr-90 containing GNEP waste streams a single phase mineralized Cs-mica phase was made by co-reacting illite clay and GNEP simulated waste. The Cs-mica accommodates up to 30% wt% Cs{sub 2}O and all the GNEP waste species, Ba, Sr, Rb including the Cs-137 transmutation to Ba-137. For reference, the cesium mineral pollucite (CsAlSi{sub 2}O{sub 6}), currently being studied for GNEP applications, can only be fabricated at {ge} 1000 C. Pollucite mineralization creates secondary aqueous waste streams and NO{sub x}. Pollucite is not tolerant of high concentrations of Ba, Sr or Rb and forces the divalent species into different mineral host phases. The pollucite can accommodate up to 33% wt% Cs{sub 2}O.

    Hydrogen has a significant future potential as an alternative energy source for the transportation sector as well as in residential homes and offices, H 2 in fuel cell power systems provides an alternative to direct fossil fuel and biomass combustion based technologies and offer the possibility for a significant reduction in greenhouse gas emission based on improved H 2 yield per unit of fossil fuel and biomass, compatibility with renewable energies and motivation to convert to a H 2 -based energy economy. Several practical techniques for H 2 production to service H 2 refuelling stations as well as homes and offices, all of which need to be located at the end of the energy distribution network, include: (1) the carbon dioxide reforming of natural gas; (2) reforming of gasoline; (3) reforming of crude ethanol. Locating the H 2 production at the end of the energy distribution network solves the well-known problems of metal fatigue and high cost of H 2 compression for long distance transportation if H 2 is produced in a large centralized plant. In addition, the ratification of the Kyoto Protocol and the need to reduce emissions of CO 2 to the atmosphere has prompted the capture and utilization of the CO 2 produced from the reforming process. In this research: (1) new efficient catalysts for each reforming process was developed; (2) a new efficient catalyst for our version of the water gas shift reaction to convert carbon monoxide to carbon dioxide was developed; (3) a new membrane separation process for production of high purity, fuel cell-grade H 2 was designed; (4) a numerical model for optimum process design and optimum utilization of resources both at the laboratory and industrial scales was developed; (5) various processes for CO 2 capture were investigated experimentally in order to achieve a net improvement in the absorption process; (6) the utilization of captured CO 2 for enhanced oil recovery and/or storage in an aging oil field were investigated; (7

    The deliberations on the amendment to the Atomic Energy Act aim at a harmonization with the Federal Immission Control Act. This holds especially for the area of regulations dealing with the installation. With its function as a licensing law for industrial installations the Federal Immission Control Act has a key position in technology and safety law. The lecture deals especially with the obligation to inform and with the right of the supervising authority to reserve its consent to minor alterations; legal qualification and lawfulness of the reservation of consent; reservation of consent to the start-up after an exchange of fuel elements; requirement of a permit for the decommissioning of installations.

  9. Measuring Short-term Energy Security

    2011-07-01

    Ensuring energy security has been at the centre of the IEA mission since its inception, following the oil crises of the early 1970s. While the security of oil supplies remains important, contemporary energy security policies must address all energy sources and cover a comprehensive range of natural, economic and political risks that affect energy sources, infrastructures and services. In response to this challenge, the IEA is currently developing a Model Of Short-term Energy Security (MOSES) to evaluate the energy security risks and resilience capacities of its member countries. The current version of MOSES covers short-term security of supply for primary energy sources and secondary fuels among IEA countries. It also lays the foundation for analysis of vulnerabilities of electricity and end-use energy sectors. MOSES contains a novel approach to analysing energy security, which can be used to identify energy security priorities, as a starting point for national energy security assessments and to track the evolution of a country's energy security profile. By grouping together countries with similar 'energy security profiles', MOSES depicts the energy security landscape of IEA countries. By extending the MOSES methodology to electricity security and energy services in the future, the IEA aims to develop a comprehensive policy-relevant perspective on global energy security. This Brochure provides and overview of the analysis and results. Readers interested in an in-depth discussion of methodology are referred to the MOSES Working Paper.

    A technique for validating electron energy resolution results measured using the modified Compton coincidence technique (MCCT) has been developed. This technique relies on comparing measured gamma-ray energy resolution with calculated values that were determined using the measured electron energy resolution results. These gamma-ray energy resolution calculations were based on Monte Carlo photon transport simulations, the measured NaI(Tl) electron response, a simplified cascade sequence, and the measured electron energy resolution results. To demonstrate this technique, MCCT-measured NaI(Tl) electron energy resolution results were used along with measured gamma-ray energy resolution results from the same NaI(Tl) crystal. Agreement to within 5% was observed for all energies considered between the calculated and measured gamma-ray energy resolution results for the NaI(Tl) crystal characterized. The calculated gamma-ray energy resolution results were also compared with previously published gamma-ray energy resolution measurements with good agreement (<10%). In addition to describing the validation technique that was developed in this study and the results, a brief review of the electron energy resolution measurements made using the MCCT is provided. Based on the results of this study, it is believed that the MCCT-measured electron energy resolution results are reliable. Thus, the MCCT and this validation technique can be used in the future to characterize the electron energy resolution of other scintillators and to determine NaI(Tl) intrinsic energy resolution

    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

    As part of a study of the science preparation of elementary school teachers, we investigated the quality of students' reasoning and explored the relationship between sophistication of reasoning and the degree to which the courses are considered inquiry oriented. First, we devised written content questions, which were open ended with the distinguishing feature of applying recently learned concepts in a new context. All the questions developed were based on a common template that required students to recognize and generalize the relevant facts or concepts and their interrelationships to suggest an applicable or plausible theory. To evaluate students' answers, we developed a rubric based on Bloom's taxonomy as revised and expanded by Anderson. Along with analyzing students' reasoning, we visited 20 universities and observed the courses in which the students were enrolled. We ranked the courses with respect to characteristics that are valued for the inquiry courses. With the large amount of collected data, we found that the likelihood of the higher cognitive processes are in favor of classes with higher measures of inquiry.

  17. Measuring energy efficiency in economics: Shadow value approach

    Science.gov (United States)

    Khademvatani, Asgar

    For decades, academic scholars and policy makers have commonly applied a simple average measure, energy intensity, for studying energy efficiency. In contrast, we introduce a distinctive marginal measure called energy shadow value (SV) for modeling energy efficiency drawn on economic theory. This thesis demonstrates energy SV advantages, conceptually and empirically, over the average measure recognizing marginal technical energy efficiency and unveiling allocative energy efficiency (energy SV to energy price). Using a dual profit function, the study illustrates how treating energy as quasi-fixed factor called quasi-fixed approach offers modeling advantages and is appropriate in developing an explicit model for energy efficiency. We address fallacies and misleading results using average measure and demonstrate energy SV advantage in inter- and intra-country energy efficiency comparison. Energy efficiency dynamics and determination of efficient allocation of energy use are shown through factors impacting energy SV: capital, technology, and environmental obligations. To validate the energy SV, we applied a dual restricted cost model using KLEM dataset for the 35 US sectors stretching from 1958 to 2000 and selected a sample of the four sectors. Following the empirical results, predicted wedges between energy price and the SV growth indicate a misallocation of energy use in stone, clay and glass (SCG) and communications (Com) sectors with more evidence in the SCG compared to the Com sector, showing overshoot in energy use relative to optimal paths and cost increases from sub-optimal energy use. The results show that energy productivity is a measure of technical efficiency and is void of information on the economic efficiency of energy use. Decomposing energy SV reveals that energy, capital and technology played key roles in energy SV increases helping to consider and analyze policy implications of energy efficiency improvement. Applying the marginal measure, we also

    Along with the oil price, concerns about the security of energy supply have soared once again in recent years.Yet, more than 30 years after the OPEC oil embargo in 1973, energy security still remains a diffuse concept. This paper conceives a statistical indicator that aims at characterizing the energy supply risk of nations that are heavily dependent on energy imports. Our indicator condenses the bulk of empirical information on the imports of fossil fuels originating from a multitude of export countries as well as data on the indigenous contribution to the domestic energy supply into a single parameter. Applying the proposed concept to empirical energy data on Germany and the U.S. (1980-2004), we find that there is a large gap in the energy supply risks between both countries, with Germany suffering much more from a tensed energy supply situation today than the U.S. (orig.)

  19. Analyzing the Effects of the Iranian Energy Subsidy Reform Plan on Short- Run Marginal Generation Cost of Electricity Using Extended Input-Output Price Model

    Full Text Available Subsidizing energy in Iran has imposed high costs on country's economy. Thus revising energy prices, on the basis of a subsidy reform plan, is a vital remedy to boost up the economy. While the direct consequence of cutting subsidies on electricity generation costs can be determined in a simple way, identifying indirect effects, which reflect higher costs for input factors such as labor, is a challenging problem. In this paper, variables such as compensation of employees and private consumption are endogenized by using extended Input-Output (I-O price model to evaluate direct and indirect effects of electricity and fuel prices increase on economic subsectors. The determination of the short-run marginal generation cost of electricity using I-O technique with taken into account the Iranian targeted subsidy plan's influences is the main goal of this paper. Marginal cost of electricity, in various scenarios of price adjustment of energy, is estimated for three conventional categories of thermal power plants. Our results show that the raising the price of energy leads to an increase in the electricity production costs. Accordingly, the production costs will be higher than 1000 Rials per kWh until 2014 as predicted in the beginning of the reform plan by electricity suppliers.

  2. Public service or commodity goods? Electricity reforms, access, and the politics of development in Tanzania

    Science.gov (United States)

    Ghanadan, Rebecca Hansing

    Since the 1990s, power sector reforms have become paramount in energy policy, catalyzing a debate in Africa about market-based service provision and the effects of reforms on access. My research seeks to move beyond the conceptual divide by grounding attention not in abstract 'market forces' but rather in how development institutions shape energy services and actually practice policy on the ground. Using the case of Tanzania, a country known for having instituted some of the most extensive reforms and a 'success story' in Africa, I find that reforms are creating large burdens and barriers for access and use of services, including: increasing costs, enforcement pressures, and measures to impose 'market' discipline. However, I also find that many of the most significant outcomes are not found in direct 'market' changes, but rather how reforms are selective, partial, and shaped by the wider needs and claims of the institutions driving reforms, so that questions of how reforms are implemented, how they are measured, and who tells the story become as important as the policies themselves. Using a multiple-arenas framework, including (i) a household and community level study of urban energy conditions, (ii) a study of service and management conditions at the national electric utility, (iii) an examination of the international policy process, and (iv) a study of the history of electricity services across colonial, post-independence, and reform periods, I show that African energy reforms are a technical and political project connecting energy to international investments, donor aid programs, and elite interests within national governments. Energy reforms also involve fundamental service changes that are reorganizing how the costs and benefits of energy systems are distributed, allocated, and managed. The effects of reform extend beyond formal services to have wide-reaching repercussions within natural resources, and uneven social dynamics on the ground. These features point

    Steam systems consume approximately one third of energy applied at US industrial facilities. To reduce energy consumption, steam system energy assessments have been conducted on a wide range of industry types over the course of 5 years through the Energy Savings Assessment (ESA) program administered by the US Department of Energy (US DOE). ESA energy assessments result in energy efficiency measure recommendations that are given potential energy and energy cost savings and potential implementation cost values. Saving and cost metrics that measure the impact recommended measures will have at facilities, described as percentages of facility baseline energy and energy cost, are developed from ESA data and used in analyses. Developed savings and cost metrics are examined along with implementation and rejection rates of recommended steam system energy efficiency measures. Based on analyses, implementation of steam system energy efficiency measures is driven primarily by cost metrics: payback period and measure implementation cost as a percentage of facility baseline energy cost (implementation cost percentage). Stated reasons for rejecting recommended measures are primarily based upon economic concerns. Additionally, implementation rates of measures are not only functions of savings and cost metrics, but time as well. - Highlights: ► We examine uptake/rejection of industrial steam system energy efficiency measures. ► We examine metrics that correspond to uptake/rejection of recommended measures. ► We examine barriers hindering steam system energy efficiency measure implementation. ► Uptake/rejection of steam measures is linked to potential cost metrics. ► Increased uptake of measures and uptake of more costly measures increases with time

    To assess the change in efficiency and total factor productivity (TFP) of the local public hospitals in Japan after the local public hospital reform launched in late 2007, which was aimed at improving the financial capability and operational efficiency of hospitals. Secondary data were collected from the Ministry of Internal Affairs and Communications on 213 eligible medium-sized hospitals, each operating 100-400 beds from FY2006 to FY2011. The improved slacks-based measure nonoriented data envelopment analysis models (Quasi-Max SBM nonoriented DEA models) were used to estimate dynamic efficiency score and Malmquist Index. The dynamic efficiency measure indicated an efficiency gain in the first several years of the reform and then was followed by a decrease. Malmquist Index analysis showed a significant decline in the TFP between 2006 and 2011. The financial improvement of medium-sized hospitals was not associated with enhancement of efficiency. Hospital efficiency was not significantly different among ownership structure and law-application system groups, but it was significantly affected by hospital location. The results indicate a need for region-tailored health care policies and for a more comprehensive reform to overcome the systemic constraints that might contribute to the decline of the TFP. © Health Research and Educational Trust.

    This study analyses farm level economic impacts of biomass production from perennial crops including Arundo donax L. (arundo), Miscanthus x giganteus (miscanthus), Panicum virgatum L. (switchgrass) and Cynara cardunculus L. (cardoon). Regional biomass supply curves are estimated with a dynamic, multi-farm, mathematical programming model. Micro-economic data for the model are generated from farm surveys covering 52 farms containing a total of 400 parcels, in Central Greece. The study also examines the potential effects of the Common Agricultural Policy reform in 2003 on regional biomass supply. Simulations show that the policy reform toward decoupled subsidies lowers the cost of biomass between 15 and 25 euro per tonne. Switchgrass appears to be the most attractive option, followed by cardoon and miscanthus. Due to high specific machinery cost, arundo is never preferred. Relative to the agricultural policy setting of Agenda 2000, the biomass potential increases more for farms of small economic size and farms with a higher share of cotton. (author)

    Highlights: • Biogas-to-electricity conversion through Solid Oxide Fuel Cell is investigated. • Two solutions are compared for biogas-to-electricity conversion. • Direct feeding by partially upgraded biogas meets with fuel cell long operation. • Best energy and exergy performances are obtained with an innovative system-design. • A sensitivity analysis on the process parameters determines its convenience margin. - Abstract: Aiming at designing biogas-to-electricity advanced systems, Solid Oxide Fuel Cells are promising candidates. They benefit from scalability on plant sizes that suit anaerobic digesters potentialities. For biogas-Solid Oxide Fuel Cells applications, the implementation of an external pre-reformer is usually considered. However, the possibility to perform direct fuel feeding to the Solid Oxide Fuel Cell offers new opportunities towards the realization of lean systems, which are competitive especially on small-scale installations (i.e. on-farm biogas-to-electricity conversion). In this frame, scientific literature is rather poor and, to cover this gap, system simulations are called for two reasons: first, to demonstrate the potential efficiency gain of new concepts; second, to provide a meaningful support for long-term experimental investigation on Solid Oxide Fuel Cells operated upon direct feeding of unreformed biogas. For that, the current study compares two system designs for biogas utilization into Solid Oxide Fuel Cells. The conventional one realizes biogas steam reforming prior the fuel cell, while the novel concept is based on direct feeding of partially upgraded biogas by means of carbon dioxide-separation membranes. As main outcome of the study, the system equipped with carbon dioxide-separation membranes achieves better performances than its conventional competitor does, scoring 51.1% energy efficiency and 52.3% exergy efficiency (compared to 37.2% and 38.6% respectively exhibited by the reformer-based system).

  13. Common morality and moral reform.

    Science.gov (United States)

    Wallace, K A

    2009-01-01

    The idea of moral reform requires that morality be more than a description of what people do value, for there has to be some measure against which to assess progress. Otherwise, any change is not reform, but simply difference. Therefore, I discuss moral reform in relation to two prescriptive approaches to common morality, which I distinguish as the foundational and the pragmatic. A foundational approach to common morality (e.g., Bernard Gert's) suggests that there is no reform of morality, but of beliefs, values, customs, and practices so as to conform with an unchanging, foundational morality. If, however, there were revision in its foundation (e.g., in rationality), then reform in morality itself would be possible. On a pragmatic view, on the other hand, common morality is relative to human flourishing, and its justification consists in its effectiveness in promoting flourishing. Morality is dependent on what in fact does promote human flourishing and therefore, could be reformed. However, a pragmatic approach, which appears more open to the possibility of moral reform, would need a more robust account of norms by which reform is measured.

    1981-01-01

    Electron spectra were obtained during two rocket flights into pulsating aurora from Southend, Saskatchewan. The first rocket launched at 1143:24 UT on February 15, 1980 flew into an aurora of background intensity 275 R of N 2 + 4278 A and showing regular pulsations with about a 17 s period. Electron spectra of Maxwellian energy distributions were observed with an average E 0 = 1.5 keV, rising to 1.8 keV during the pulsations. There was one-to-one correspondence between the electron energy modulation and the observed optical pulsations. The second rocket, launched at 1009:10 UT on February 23, flew into a diffuse auroral surface of intensity 800 R of N 2 + 4278 A and with somewhat irregular pulsations. The electron spectra were again of Maxwellian energy distribution with an average E 0 = 1.8 keV increasing to 2.1 keV during the pulsations. The results from these flights suggest that pulsating auroras occurring in the morning sector may be quite commonly excited by low energy electrons. The optical pulsations are due to periodic increases in the energy of the electrons with the source of modulation in the vicintiy of the geomagnetic equatorial plane. (auth)

    1995-01-01

    Low energy prices in Iran do not reflect economic costs. Further distortions exist in the tariff structures of most energy sources and in their relative prices. Price reform is a key policy element for achieving increased energy conservation and economic substitution. Subsidies should be made transparent and explained by the Government, and, when eliminated, they could be compensated by target measures or direct subsidies for low income households. Price reforms are under way, with some caution though, because of possible political and inflationary consequences. In order to better understand the need for price reforms a brief analysis of the current energy pricing policy is provided there. (author)

    1978-01-01

    DCARR, the Differential Critical Angle Reflection Refraction detector system, is described. This detector was designed to measure low-energy x rays, 500 to 5000 eV, with a high degree of resolution, 250 eV. DCARR was developed because these low-energy measurements are of interest in the diagnostics of x-radiation in nuclear tests and available equipment could not make measurements at this low an energy in field tests. DCARR is a versatile piece of equipment that can also be used as a laboratory tool, such as in measuring the low-energy x rays emitted by lasers and various x-ray machines

    Energy efficiency policy is seen as a very important activity by almost all policy makers. In practical energy policy analysis, the typical indicator used as a proxy for energy efficiency is energy intensity. However, this simple indicator is not necessarily an accurate measure given changes in energy intensity are a function of changes in several factors as well as ‘true’ energy efficiency; hence, it is difficult to make conclusions for energy policy based upon simple energy intensity measures. Related to this, some published academic papers over the last few years have attempted to use empirical methods to measure the efficient use of energy based on the economic theory of production. However, these studies do not generally provide a systematic discussion of the theoretical basis nor the possible parametric empirical approaches that are available for estimating the level of energy efficiency. The objective of this paper, therefore, is to sketch out and explain from an economic perspective the theoretical framework as well as the empirical methods for measuring the level of energy efficiency. Additionally, in the second part of the paper, some of the empirical studies that have attempted to measure energy efficiency using such an economics approach are summarized and discussed.

    Highlights: • Tri-reforming of methane is an energy efficient process to produce synthesis gas. • Nanocrystalline Ni–ZrO_2 catalyst is prepared for tri-reforming of methane. • Strong metal-support interaction is the driving force for high activity. • The process produces synthesis gas with H_2/CO ratio of around 2. • The produced synthesis gas can be used to synthesize methanol. - Abstract: We report the synthesis of nanocrystalline Ni–ZrO_2 catalyst for tri-reforming of methane (5CH_4 + O_2 + CO_2 + 2H_2O → 6CO + 12H_2) to produce synthesis gas with H_2/CO mole ratio ∼2. Nanocrystalline Ni–ZrO_2 catalyst of size between 10 and 40 nm was prepared by hydrothermal method using cetyltrimethylammonium bromide (CTAB) as a surfactant. The prepared catalysts were characterized by N_2-physisorption studies, X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), temperature programmed reduction (TPR), H_2-chemisorpton, thermo-gravimetric analysis (TGA), Inductively coupled plasma atomic emission spectroscopy (ICP-AES) and X-ray photoelectron spectroscopy (XPS). The catalytic activity was monitored over temperature range between 500 and 800 °C. Different reaction parameters like temperature, Ni-loading, gas hourly space velocity (GHSV) and time on stream (TOS) were studied in detail. 4.8 wt% Ni loading for Ni–ZrO_2 catalyst was found to be the optimum Ni loading which showed the superior catalytic activity for methane tri-reforming. The catalyst was found to be stable for more than 100 h on time on stream with methane, carbon dioxide and steam conversion of ∼95% at 800 °C. The H_2/CO ratio was almost constant to 1.9 throughout the time on stream experiment. Highly dispersed nickel and the presence of strong metal support interaction were found to be the key factor for the superior activity of the catalyst. The effect of O_2 and H_2O concentration on reactant conversions and H_2/CO ratios were also

    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.

    New measurements of the high energy deuteron photodisintegration differential cross section were made at the Thomas Jefferson National Accelerator Facility in Newport News, Virginia. Two experiments were performed. Experiment E96-003 was performed in experimental Hall C. The measurements were designed to extend the highest energy differential cross section values to 5.5 GeV incident photon energy at forward angles. This builds upon previous high energy measurements in which scaling consistent with the pQCD constituent counting rules was observed at 90 degrees and 70 degrees in the center of mass. From the new measurements, a threshold for the onset of constituent counting rule scaling seems present at transverse momentum approximately 1.3 GeV/c. The second experiment, E99-008, was performed in experimental Hall A. The measurements were designed to explore the angular distribution of the differential cross section at constant energy. The measurements were made symmetric about 90 degrees

    This report examines several different measures of industrial output for use in constructing estimates of industrial energy efficiency and discusses some reasons for differences between the measures. Estimates of volume-based measures of output, as well as 3 value-based measures of output (value of production, value of shipments, and value added), are evaluated for 15 separate 4-digit industries. Volatility, simple growth rate, and trend growth rate estimates are made for each industry and each measure of output. Correlations are made between the volume- and value-based measures of output. Historical energy use data are collected for 5 of the industries for making energy- intensity estimates. Growth rates in energy use, energy intensity, and correlations between volume- and value-based measures of energy intensity are computed. There is large variability in growth trend estimates both long term and from year to year. While there is a high correlation between volume- and value-based measures of output for a few industries, typically the correlation is low, and this is exacerbated for estimates of energy intensity. Analysis revealed reasons for these low correlations. It appears that substantial work must be done before reliable measures of trends in the energy efficiency of industry can be accurately characterized.

    Topics discussed include measuring Λ, tests of QCD using hard scattering processes, and measuring parton distributions. In each case, any opportunities and advantages afforded by the unique features of the SSC are emphasized. The working group on structure functions was charged with investigating two specific questions: (1) How well are the various parton distributions known in the kinematic region relevant to calculations for the SSC. (2) What new information can be learned about parton distributions at the SSC. Especially for this working group, the advantages of having a fixed-target facility at the SSC for the measurement of the parton distributions with multi-TeV leptons, were to be examined. 15 references

  8. Measuring energy efficiency in the United States` economy: A beginning

    1995-10-01

    Energy efficiency is a vital component of the Nation`s energy strategy. One of the Department of Energy`s missions are to promote energy efficiency to help the Nation manage its energy resources. The ability to define and measure energy efficiency is essential to this objective. In the absence of consistent defensible measures, energy efficiency is a vague, subjective concept that engenders directionless speculation and confusion rather than insightful analysis. The task of defining and measuring energy efficiency and creating statistical measures as descriptors is a daunting one. This publication is not a final product, but is EIA`s first attempt to define and measure energy efficiency in a systematic and robust manner for each of the sectors and the United States economy as a whole. In this process, EIA has relied on discussions, customer reviews, in-house reviews, and seminars that have focused on energy efficiency in each of the sectors. EIA solicits the continued participation of its customers in further refining this work.

    Lockwood, G.J.; Miller, G.H.; Halbleib, J.A. Sr.

    Results of a series of experiments in which backscattered energy has been determined from precise energy deposition measurements using an improved technique are presented. The fraction of the energy backscattered for electrons incident on Be, Ti, Mo, and Ta is determined as a function of energy and angle of incidence. The improved technique for the absolute measurement of energy deposition using calorimeters involves square-wave (on-off) modulation of the beam. Uncertainties in the measured backscattered energy are 1 to 6 percent, except for Be at normal incidence where they must agree by definition. Experiment and theory agree quite well for Mo and Be at 60 0 . The measured data for Ta and Ti are clearly higher than the calculated results, which is not completely understood. (U.S.)

    A calorimetric sensor with several novel design features has been developed. These sensors will provide an accurate sampling of thermal power density and energy deposition from proton beams incident on target components of accelerator-based systems, such as the Accelerator Production of Tritium Project (APT) and the Spallation Neutron Source (SNS). A small, solid slug (volume = 0.347 cc) of target material is suspended by kevlar fibers and surrounded by an adiabatic enclosure in an insulating vacuum canister of stainless steel construction. The slug is in thermal contact with a low-mass, calibrated, 100-kΩ thermistor. Power deposition caused by the passage of radiation through the slug is calculated from the rate of temperature rise of the slug. The authors have chosen slugs composed of Pb, Al, and LiAl

    The creation of the Energy Community of South Eastern Europe in 2005 committed countries in South Eastern Europe to liberalize their energy markets in accordance to EU regulations. The Government of Montenegro is thus in the process of reforming its energy sector, which includes an electricity tariff reform. This paper analyzes the environmental and social impacts of an increase in residential electricity tariffs contemplated - which is expected to range anywhere from 40 to over 100% increase. As this analysis shows, such a significant price rise will impose a heavy burden on the poor households and it may adversely affect the environment. In an ex ante investigation of the welfare impact of this price increase on households in Montenegro, we show that the anticipated price increase will result in a very significant increase in households' energy expenditures. A simulation of alternative policy measures analyzes the impact of different tariff levels and structures, focusing on the poor and vulnerable households. Higher electricity prices could also significantly increase the proportion of households using fuelwood for space heating. Thus the level of fuelwood consumption should be carefully monitored under the electricity tariff reforms and the Government of Montenegro should combine the tariff reforms with a carefully evaluated set of policy measures to mitigate the effect of the electricity price increase on the poor.

    The uranium scintillator calorimeter of the ZEUS detector is designed to achieve an excellent energy calibration and the best possible energy resolution for jets. Therefore the response of the prototype calorimeter to jets has been measured using an interaction trigger. The mean response and energy resolution was measured for jets of 50 GeV - 100 GeV and compared to the one for pions. Within the ZEUS detector dead material is placed in front of the calorimeter. The influence of 4 cm and 10 cm thick aluminium absorbers in front of the calorimeter was measured. The charged multiplicity was measured in front and behind the aluminium absorber. With these multiplicities the energy loss in the absorber is corrected. The correction has been done so that the mean response with absorber is equal to the mean response without absorber. The improvement of the energy resolution is investigated. The measured results are compared with Monte Carlo simulations. (orig.) [de

  18. ICT energy efficiency in higher education. Continuous measurement and monitoring

    2011-11-15

    Power consumption of information and communications technology (ICT) is rising rapidly worldwide. Reducing (the growth in) energy demand helps to achieve sustainability goals in the area of energy resource depletion, energy security, economy, and ecology. Various governments and industry consortia have set out policies and agreements to reduce the (growth in) demand for energy. In the MJA3 agreements in the Netherlands, various organizations, including all 14 universities and 39 universities of applied sciences pledged to achieve 30% increase in energy efficiency in 2020 compared to 2005. In this report, we argue that using the number of kilowatt-hours of final electricity used for ICT per enrolled student per day (kWh/st/d), should be used as the primary metric for ICT energy efficiency in higher education. For other uses of electricity than ICT in higher education, we express electricity use in kilowatthours per person per day (kWh/p/d). Applying continuous monitoring and management of ICT energy is one approach one could take to increase ICT energy efficiency in education. In households, providing direct (i.e. real-time) feedback about energy use typically results in 5-15% energy savings, whereas indirect feedback (provided some time after consumption occurs), results in less energy savings, typically 0-10%. Continuous measurement of ICT electricity use can be done in a variety of ways. In this report, we distinguish and describe four major measurement approaches: (1) In-line meters, which require breaking the electrical circuit to install the meter; (2) clamp-on-meters, which can be wrapped around a wire; (3) add-ons to existing energy meters, which use analog or digital ports of existing energy meters; (4) software-only measurement, which uses existing network interfaces, protocols and APIs. A measurement approach can be used at one or more aggregation levels: at building level (to measure all electrical energy used in a building, e.g. a datacenter); at

    Full Text Available A more objective method for measuring the energy needs of businesses, System Energy Assessment (SEA, measures the combined impacts of material supply chains and service supply chains, to assess businesses as whole self-managing net-energy systems. The method is demonstrated using a model Wind Farm, and defines a physical measure of their energy productivity for society (EROI-S, a ratio of total energy delivered to total energy expended. Energy use records for technology and proxy measures for clearly understood but not individually recorded energy uses for services are combined for a whole system estimate of consumption required for production. Current methods count only energy needs for technology. Business services outsource their own energy needs to operate, leaving no traceable record. That uncounted business energy demand is often 80% of the total, an amount of “dark energy” hidden from view, discovered by finding the average energy estimated needs for businesses far below the world average energy consumed per dollar of GDP. Presently for lack of information the energy needs of business services are counted to be “0”. Our default assumption is to treat them as “average”. The result is a hard measure of total business demand for energy services, a “Scope 4” energy use or GHG impact assessment. Counting recorded energy uses and discounting unrecorded ones misrepresents labor intensive work as highly energy efficient. The result confirms a similar finding by Hall et al. in 1981 [1]. We use exhaustive search for what a business needs to operate as a whole, tracing internal business relationships rather than energy data, to locate its natural physical boundary as a working unit, and so define a business as a physical rather than statistical subject of scientific study.

    Research in recent years has demonstrated the efficient use of solar thermal energy for driving endothermic chemical reforming reactions in which hydrocarbons are reacted to form synthesis gas (syngas). Closed-loop reforming/methanation systems can be used for storage and transport of process heat and for short-term storage for peaking power generation. Open-loop systems can be used for direct fuel production; for production of syngas feedstock for further processing to specialty chemicals and plastics and bulk ammonia, hydrogen, and liquid fuels; and directly for industrial processes such as iron ore reduction. In addition, reforming of organic chemical wastes and hazardous materials can be accomplished using the high-efficiency destruction capabilities of steam reforming. To help identify the most promising areas for future development of this technology, we discuss in this paper the economics and market potential of these applications.

  2. A Framework for Comparative Assessments of Energy Efficiency Policy Measures

    Blum, Helcio; Atkinson, Barbara; Lekov, Alex

    2011-05-24

    When policy makers propose new policies, there is a need to assess the costs and benefits of the proposed policy measures, to compare them to existing and alternative policies, and to rank them according to their effectiveness. In the case of equipment energy efficiency regulations, comparing the effects of a range of alternative policy measures requires evaluating their effects on consumers’ budgets, on national energy consumption and economics, and on the environment. Such an approach should be able to represent in a single framework the particularities of each policy measure and provide comparable results. This report presents an integrated methodological framework to assess prospectively the energy, economic, and environmental impacts of energy efficiency policy measures. The framework builds on the premise that the comparative assessment of energy efficiency policy measures should (a) rely on a common set of primary data and parameters, (b) follow a single functional approach to estimate the energy, economic, and emissions savings resulting from each assessed measure, and (c) present results through a set of comparable indicators. This framework elaborates on models that the U.S. Department of Energy (DOE) has used in support of its rulemakings on mandatory energy efficiency standards. In addition to a rigorous analysis of the impacts of mandatory standards, DOE compares the projected results of alternative policy measures to those projected to be achieved by the standards. The framework extends such an approach to provide a broad, generic methodology, with no geographic or sectoral limitations, that is useful for evaluating any type of equipment energy efficiency market intervention. The report concludes with a demonstration of how to use the framework to compare the impacts estimated for twelve policy measures focusing on increasing the energy efficiency of gas furnaces in the United States.

    In an era of increasing globalization, secure and affordable energy supplies are an essential requirement for economies to work, much less develop and grow in the long term. The present study, Energy security of supply - indicators for measuring vulnerability and risk, develops a broad methodical assessment concept to raise awareness among policy makers and the public regarding the vulnerability of energy supplies to potential energy crises. It explores the different aspects of vulnerability, from the primary energy level to energy infrastructure (storage, networks, power plant parks) to the efficiency and cost of energy consumption for end users. The individual characteristics of the formal concept were quantitatively evaluated for several OECD regions (Germany, UK, Sweden, Poland, Italy, France and the US) using a comprehensive empirical database and reduced to a single indicator for assessing energy supply vulnerability. Part of the database comprises historical observations for the period between 1978 and 2007.(author).

    2017-11-01

    The present paper describes different energy production, recovery and saving measures which can be applied in an integrated urban water system. Production measures are often based on the installation of photovoltaic systems; the recovery measures are commonly based on hydraulic turbines, exploiting the available pressure potential to produce energy; saving measures are based on substitution of old pumps with higher efficiency ones. The possibility of substituting some of the pipes of the water supply system can be also considered in a recovery scenario in order to reduce leakages and recovery part of the energy needed for water transport and treatment. The reduction of water losses can be obtained through the Active Leakage Control (ALC) strategies resulting in a reduction in energy consumption and in environmental impact. Measures were applied to a real case study to tested it the efficiency, i.e., the integrated urban water system of the Palermo metropolitan area in Sicily (Italy).

    The energy stored in alkali-halogen crystals after X-ray irradiation is studied at 11 K. Using a heat flux calorimeter designed especially for this experiment, single crystals are irradiated and the energy release is recorded as the temperature is increased proportional to time from 10 K to 50 K. The energy release spectra are compared with relevant optical measurements and thus a relation between energy release and tempering of point defects is established. The energy release peaks can be assigned definitly to tempering stages of the Frenkel pairs. For explanation a simple model is proposed. (orig./HPOE) [de

    1996-12-31

    An important commitment in the UN Framework Convention on Climate Change is to conduct mitigation analysis and to communicate climate change measures and policies. In major part reducing CO{sub 2} as well as the other greenhouse gas emissions in Kazakstan, can be a side-product of measures addressed to increasing energy efficiency. Since such measures are very important for the national economy, mitigation strategies in the energy sector of Kazakstan are directly connected with the general national strategy of the energy sector development. This paper outlines the main measures and technologies in energy sector of Kazakstan which can lead to GHG emissions reduction and presents the results of current mitigation assessment. The mitigation analysis is addressed to energy production sector. A baseline and six mitigation scenarios were developed to evaluate the most attractive mitigation options, focusing on specific technologies which have been already included in sustainable energy programs. According to the baseline projection, Kazakstan`s CO{sub 2} emissions will not exceed their 1990 level until 2005. The potential for CO{sub 2} emission reduction is estimated to be about 11 % of the base line emission level by the end of considered period (in 2020). The main mitigation options in the energy production sector in terms of mitigation potential and technical and economical feasibility include rehabilitation of thermal power plants aimed to increasing efficiency, use of nuclear energy and further expansion in the use of hydro energy based on small hydroelectric power plants.

    The energy gain through the drift tube linac is a function of the synchronous phase, therefore, the output beam energy from DTL can be affected by the RF phase setting in low-level RF (LLRF) system. The DTL at Korea Multi-purpose Accelerator Complex (KOMAC) consists of 11 tanks and the RF phase setting in each tank should be matched for synchronous acceleration in successive tanks. That means a proper setting of RF phase in each DTL tank is critical for efficient and loss-free operation. The matching RF phase can be determined based on the output energy measurement from the DTL tank. The beam energy can be measured by several methods. For example, we can use a bending magnet to determine the beam energy because the higher momentum of beam means the less deflection angle in the fixed magnetic field. By measuring the range of proton beam through a material with known stopping power also can be utilized to determine the beam energy. We used a well-known time-of-flight method to determine the output beam energy from the DTL tank by measuring beam phase with a beam position monitor (BPM). Based on the energy measurement results, proper RF operating point could be obtained. We performed a RF phase scan to determine the output beam energy from KOMAC DTL by using a time-of-flight method and to set RF operating point precisely. The measured beam energy was compared with a beam dynamics simulation and showed a good agreement. RF phase setting is critical issue for the efficient operation of the proton accelerator, we have a plan to implement and integrate the RF phase measurement system into an accelerator control system for future need.

    Environmental sustainability agenda are generally compromised by energy, water, and food production resources, while in the recent waves of global financial crisis, it mediates to increase the intensity of air pollutants, which largely affected the less developing countries due to their ease of environmental regulation policies and lack of optimal utilization of economic resources. Sub-Saharan African (SSA) countries are no exception that majorly hit by the recent global financial crisis, which affected the country's natural environment through the channel of unsustainable energy-water-food production. The study employed panel random effect model that addresses the country-specific time-invariant shocks to examine the non-linear relationship between water-energy-food resources and air pollutants in a panel of 19 selected SSA countries, for a period of 2000-2014. The results confirmed the carbon-fossil-methane environmental Kuznets curve (EKC) that turned into inverted U-shaped relationships in a panel of selected SSA countries. Food resources largely affected greenhouse gas (GHG), methane (CH 4 ), and nitrous oxide (N 2 O) emissions while water resource decreases carbon dioxide (CO 2 ), fossil fuel, and CH 4 emissions in a region. Energy efficiency improves air quality indicators while industry value added increases CO 2 emissions, fossil fuel energy, and GHG emissions. Global financial crisis increases the risk of climate change across countries. The study concludes that although SSA countries strive hard to take some "good" initiatives to reduce environmental degradation in a form of improved water and energy sources, however, due to lack of optimal utilization of food resources and global financial constraints, it leads to "the bad" and "the ugly" sustainability reforms in a region.

    A thermodynamic equilibrium analysis on steam reforming process to utilize acetone-butanol-ethanol-water mixture obtained from biomass fermentation as biorenewable fuel has been performed to produce clean energy carrier H 2 via non-stoichiometric approach namely Gibbs free energy minimization method. The effect of process variables such as temperature (573-1473 K), pressure (1-10 atm), and steam/fuel molar feed ratio (F ABE  = 5.5-12) have been investigated on equilibrium compositions of products, H 2 , CO, CO 2 , CH 4 and solid carbon. The best suitable conditions for maximization of desired product H 2 , suppression of CH 4 , and inhibition of solid carbon are 973 K, 1 atm, steam/fuel molar feed ratio = 12. Under these conditions, the maximum molar production of hydrogen is 8.35 with negligible formation of carbon and methane. Furthermore, the energy requirement per mol of H 2 (48.96 kJ), thermal efficiency (69.13%), exergy efficiency (55.09%), exergy destruction (85.36 kJ/mol), and generated entropy (0.29 kJ/mol.K) have been achieved at same operating conditions.

  13. Constitutional questions on a reform of the Atomic Energy Act, in particular on the distribution of administrative competence within the Federation

    Steinberg, R.

    1991-01-01

    The lecture deals in particular with the constitutional framing and the principles of the Laender administration on behalf of the Federal Government, the responsibility of the Land for subject matters and action and submit reports, court proceedings the barrier of Paragraph 85 II of the Basic Law: 'Directives'. The final conclusion is that the proposals to shift the administrative responsibilities for the execution of the Atomic Energy Act to the Federation and those for a supposed elimination of weak points in the Laender administration on behalf of the Federal Government are highly questionable in the face of constitutional law. The attempt at a new interpretation of the regulations on the Federal Government is equal to the intention of amending the Constitution without a law for such an amendment. What poses the foremost problems, however, is the perspective that is to set the course here for the reform of the Atomic Energy Act: strengthening of the Federation and further weakening of the competences of the Laender that constitute their autonomous statehood. No consideration is given to the point that structural changes to the atomic energy administration must necessarily effect other areas of the Laender administration on behalf of the Federal Government where the work done over more than 40 years has been to everyone's satisfaction. Then again the intention of fostering the nuclear industry by strengthening the Federal Government might backfire after the next elections to the Bundestag. (orig./HSCH) [de

  16. Negative vacuum energy densities and the causal diamond measure

    International Nuclear Information System (INIS)

    Salem, Michael P.

    2009-01-01

    Arguably a major success of the landscape picture is the prediction of a small, nonzero vacuum energy density. The details of this prediction depend in part on how the diverging spacetime volume of the multiverse is regulated, a question that remains unresolved. One proposal, the causal diamond measure, has demonstrated many phenomenological successes, including predicting a distribution of positive vacuum energy densities in good agreement with observation. In the string landscape, however, the vacuum energy density is expected to take positive and negative values. We find the causal diamond measure gives a poor fit to observation in such a landscape - in particular, 99.6% of observers in galaxies seemingly just like ours measure a vacuum energy density smaller than we do, most of them measuring it to be negative.

  17. Could dark energy be measured in the lab?

    International Nuclear Information System (INIS)

    Beck, Christian; Mackey, Michael C.

    2005-01-01

    The experimentally measured spectral density of current noise in Josephson junctions provides direct evidence for the existence of zero-point fluctuations. Assuming that the total vacuum energy associated with these fluctuations cannot exceed the presently measured dark energy of the universe, we predict an upper cutoff frequency of ν c =(1.69+/-0.05)x10 12 Hz for the measured frequency spectrum of zero-point fluctuations in the Josephson junction. The largest frequencies that have been reached in the experiments are of the same order of magnitude as ν c and provide a lower bound on the dark energy density of the universe. It is shown that suppressed zero-point fluctuations above a given cutoff frequency can lead to 1/f noise. We propose an experiment which may help to measure some of the properties of dark energy in the lab

  19. Measuring the security of energy exports demand in OPEC economies

    International Nuclear Information System (INIS)

    Dike, Jude Chukwudi

    2013-01-01

    One of the objectives of OPEC is the security of demand for the crude oil exports of its members. Achieving this objective is imperative with the projected decline in OECD countries' crude oil demand among other crude oil demand shocks. This paper focuses on determining the external crude oil demand security risks of OPEC member states. In assessing these risks, this study introduces two indexes. The first index, Risky Energy Exports Demand (REED), indicates the level of energy export demand security risks for OPEC members. It combines measures of export dependence, economic dependence, monopsony risk and transportation risk. The second index, Contribution to OPEC Risk Exposure (CORE), indicates the individual contribution of the OPEC members to OPEC's risk exposure. This study utilises the disaggregated index approach in measuring energy demand security risks for crude oil and natural gas and involves a country level analysis. With the disaggregated approach, the study shows that OPEC's energy export demand security risks differ across countries and energy types. - Highlights: • REED and CORE indexes are suitable measures for energy exports demand security risk. • The indexes show that energy demand security risk is different for each OPEC country. • The countries contribution to OPEC's energy demand security risk is also different. • The outcome is necessary for OPEC's common energy and climate change policies. • The outcome makes a case for oil demand security as a topical issue in the literature

    1997-01-01

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

    2010-01-01

    The nature of dark energy can be probed not only through its equation of state but also through its microphysics, characterized by the sound speed of perturbations to the dark energy density and pressure. As the sound speed drops below the speed of light, dark energy inhomogeneities increase, affecting both cosmic microwave background and matter power spectra. We show that current data can put no significant constraints on the value of the sound speed when dark energy is purely a recent phenomenon, but can begin to show more interesting results for early dark energy models. For example, the best fit model for current data has a slight preference for dynamics [w(a)≠-1], degrees of freedom distinct from quintessence (c s ≠1), and early presence of dark energy [Ω de (a<<1)≠0]. Future data may open a new window on dark energy by measuring its spatial as well as time variation.

    1998-03-01

    For analytical evaluation of effects of environmental protection measures, energy conservation measures, new energy promotion measures, etc., a very-long term energy supply/demand model was developed and used for a simulational study. The model is composed of the models of macro economics, secondary energy prices, new energy introduction, and energy supply/demand. The feature is that the amount of new energy introduction is measuringly analyzed based on the cost and market scale, and integratedly estimated in a frame of energy supply/demand of the whole Japan. As a result of the simulation, energy source as of 2030 is composed of coal (17%), oil (44%) and nuclear power (15%) in the case of the economic growth as viewed optimistically. Contrarily, in the case of it as viewed pesimistically, energy source is composed of coal (11%), oil (40%) and nuclear power (22%). CO2 emission is -12.4% in the case of the new energy promotion than in the standard case. 7 refs., 79 figs., 107 tabs.

  4. Tariffing of energy measured consumers in the distribution network

    International Nuclear Information System (INIS)

    2006-01-01

    Criteria for socio-economic effective tariffing of energy-measured clients in the distribution network are discussed (i.e. households, leisure homes and smaller business clients), this means consumers that do not have hourly measurements or effect measurements. The tariffs should be based on variable segments that reflect short-term marginal costs in the network (in practice loss of transfer) and fixed segments that to the least extent possible influence the consumers' decisions in the choice of energy solutions, both in short term and long term. High-priced energy segments and effect based fixed segments may give unfortunate socio-economic price signals compared to the marginal long-term network costs. A fixed segment per measurement unit is in principle completely neutral, but it is to some extent vulnerable to strategic adjustments if the consumers choose collective measurement. This is not necessarily a big problem in practice (author)

  5. High temperature ceramic-tubed reformer

    Williams, Joseph J.; Rosenberg, Robert A.; McDonough, Lane J.

    1990-03-01

    The overall objective of the HiPHES project is to develop an advanced high-pressure heat exchanger for a convective steam/methane reformer. The HiPHES steam/methane reformer is a convective, shell and tube type, catalytic reactor. The use of ceramic tubes will allow reaction temperature higher than the current state-of-the-art outlet temperatures of about 1600 F using metal tubes. Higher reaction temperatures increase feedstock conversion to synthesis gas and reduce energy requirements compared to currently available radiant-box type reformers using metal tubes. Reforming of natural gas is the principal method used to produce synthesis gas (primarily hydrogen and carbon monoxide, H2 and CO) which is used to produce hydrogen (for refinery upgrading), methanol, as well as several other important materials. The HiPHES reformer development is an extension of Stone and Webster's efforts to develop a metal-tubed convective reformer integrated with a gas turbine cycle.

    This paper analyses the factors behind the deployment of renewable energy, focusing particularly on the effect of energy efficiency policies and measures. The impact of these factors is appraised within the context of several phases of the use of renewable sources. We therefore apply the quantile regression technique to a set of 21 European Countries in two time spans: from 1990 to 1998, and from 1999 to 2006. We control variables of policy, environment, socioeconomic characteristics, and electricity generation. For the second period, energy efficiency policies and measures concerning renewable sources effectively promote renewables, namely in the take-off phase. We shed light on the lobbying effect of traditional energy industries, showing that it depends both on the period under analysis, and on the kind of traditional energy source.

    External actors can influence potential adopters to adopt energy efficiency measures. In Sweden energy advisers are one such actor group who provides energy advice and information to the end users. Currently, all municipalities offer energy advisers' service. The success of such service for improvement of energy efficiency of detached houses depends on homeowners' perception towards it. In this context we conducted a national survey of about 3000 owners of detached houses through stratified random sampling method in 2008 summer. We found that majority of owners' of detached houses consider energy advisers as an important source of information. Furthermore, many homeowners who contacted energy advisers for advice had implemented the suggestions. However, only a few homeowners had actually contacted energy advisers. Our findings suggest that it is beneficial to continue the energy adviser service, but more efforts are needed to increase homeowners' awareness of and satisfaction with such services.

  9. Energy Efficiency Measures to Incorporate into Remodeling Projects

    2014-12-01

    Energy improvements in a home are often approached as one concerted effort, beginning with a simple walk-through assessment or more in-depth energy audit and followed by the installation of recommended energy measures. While this approach allows for systems thinking to guide the efforts, comprehensive energy improvements of this nature are undertaken by a relatively small number of U.S. households compared to piecemeal remodeling efforts. In this report, the U.S Department of Energy Building America Retrofit Alliance research team examines the improvement of a home’s energy performance in an opportunistic way by examining what can be done to incorporate energy efficiency measures into general remodeling work and home repair projects. This allows for energy efficiency upgrades to occur at the same time as remodeling proejcts. There are challenges to this approach, not the least of which being that the work will take place over time in potentially many separate projects. The opportunity to improve a home’s energy efficiency at one time expands or contracts with the scope of the remodel. As such, guidance on how to do each piece thoughtfully and with consideration for potential future projects, is critical.

    In calorimetric method, ion energy is determined based on the temperature changes during radiation of an absorbing material, radiation current and heat capacity of the calorimeter. This method is convenient and its measuring procedures are simple as well as the measuring apparatus. Here, the temperature changes of the calorimeter during {sup 14}N ion beam radiation were determined. The temperature increased linearly when irradiated with {sup 14}N{sup 3+}, 8.3 MeV or {sup 14}N{sup 2+}, 6 MeV, but not linearly for {sup 14}N{sup 1+}, 3.6 MeV, resulting in a comparatively large error. Thus, the measurement of ion energy by calorimetric method was found available as a convenient method for an accelerator having an energy stability less than 10{sup -3}. Especially this method seems to be useful for low-energy ion accelerator or ion injecting apparatus. (M.N.)

    Through the Chicagoland Single Family Housing Characterization and Retrofit Prioritization report, the Partnership for Advanced Residential Retrofit research team characterized 15 housing types in the Chicagoland region based on assessor data, utility billing history, and available data from prior energy efficiency programs. Within these 15 groups, a subset showed the greatest opportunity for energy savings based on BEopt Version 1.1 modeling of potential energy efficiency package options and the percent of the housing stock represented by each group. In this project, collected field data from a whole-home program in Illinois are utilized to compare marketplace-installed measures to the energy saving optimal packages previously developed for the 15 housing types. Housing type, conditions, energy efficiency measures installed, and retrofit cost information were collected from 19 homes that participated in the Illinois Home Performance with ENERGY STAR program in 2012, representing eight of the characterized housing groups. Two were selected for further case study analysis to provide an illustration of the differences between optimal and actually installed measures. Taken together, these homes are representative of 34.8% of the Chicagoland residential building stock. In one instance, actual installed measures closely matched optimal recommended measures.

    2010-01-01

    This paper analyzes carbon dioxide (CO 2 ) emissions related to energy consumption for electricity generation in four Latin-American countries in the context of the liberalization process. From 1990 to 2006, power plants based on renewable energy sources decreased its share in power installed capacity, and the carbon index defined as CO 2 emission by unit of energy for electricity production stayed almost constant for all countries with the exception of Colombia, where the index reduced due to increase in hydroelectricity generation in the last years. The paper also presents a new set of policies to promote renewable energy sources that have been developed in the four countries. The paper concludes that restructuring did not bring about environmental benefits related to a decrease in CO 2 emissions because this depend on the existence of committed policies, and dedicated institutional and regulatory frameworks.

  13. Internal reforming of methane in solid oxide fuel cell systems

    Science.gov (United States)

    Peters, R.; Dahl, R.; Klüttgen, U.; Palm, C.; Stolten, D.

    Internal reforming is an attractive option offering a significant cost reduction, higher efficiencies and faster load response of a solid oxide fuel cell (SOFC) power plant. However, complete internal reforming may lead to several problems which can be avoided with partial pre-reforming of natural gas. In order to achieve high total plant efficiency associated with low energy consumption and low investment costs, a process concept has been developed based on all the components of the SOFC system. In the case of anode gas recycling an internal steam circuit exists. This has the advantage that there is no need for an external steam generator and the steam concentration in the anode gas is reduced. However, anode gas recycling has to be proven by experiments in a pre-reformer and for internal reforming. The addition of carbon dioxide clearly shows a decrease in catalyst activity, while for temperatures higher than 1000 K hydrogen leads to an increase of the measured methane conversion rates.

    In the ideal electricity market, electricity prices give the signal that supply and demand are balanced in real time, flexibility is offered and cost and energy efficiency are achieved. When electricity is scarce, high prices mobilise the operation of storage facilities, load management and generation plants. If electricity is available in surplus, the low prices attract additional customers. Ideally, prices also stimulate the right investments for a reliable, efficient and climate-friendly electricity system - even at the borders of the electricity, heating and transport sectors. In reality, 75 to 80 percent of the electricity price for most consumers consists of government-regulated, regulated price components. Energy taxes, grid charges, taxes and levies total around 55 billion euros per year and fulfil important functions in the financing of the electricity system and energy turnaround. However, they often almost completely overlap the coordinating price signal in wholesale. Offering flexibility is hardly worthwhile because taxes, fees, levies and charges are due immediately. The price signals are also not right at the sector borders: heating oil and natural gas, diesel and petrol are taxed according to other criteria than electricity; there are misguided incentives in the choice of energy sources and climate protection. The reform of the tax, remuneration, levy and levy system is therefore urgently needed, but it is a complex undertaking. Agora Energiewende, with the support of E-Bridge, ZEW and TU Clausthal, has carried out an analysis of the current price structure and explored the scope for a fundamental reform of the existing system. In this way, we want to lay a foundation for the development of concrete reform proposals, which will be worked out in a further study.

  16. Effectiveness of policy measures in transforming the energy system

    International Nuclear Information System (INIS)

    Lund, P.D.

    2007-01-01

    The effectiveness of public policy measures in creating energy impacts were investigated through 20 policy cases on renewable energy and efficient energy use. The policies were grouped into subsidy-type and catalyzing measures based on the use of the public financial resources. The policy cost of subsidies ranged from 1 Euro/MWh up to over 100 Euro/MWh, the feed-in tariffs being clearly the most expensive choice. The public measures that strive for catalyzing market breakthroughs lie in the range 0.1-1 Euro/MWh, but some business driven and procurement type measures could come down to even 0.01 Euro/MWh. The policy costs observed could decrease by 25-60% if accounting for lagging energy impacts. The better policy efficiency of catalytic measures is most likely due to a stronger market and business sensitiveness, understanding of market needs, and focusing more on the end-use sector with active stakeholder involvement. The magnitude of the energy impacts were in average larger from the subsidy instruments but a few end-use technologies linked to catalytic measures reached even higher effects due to the strong market penetration achieved.

The policy cost of subsidies ranged from 1 Euro /MWh up to over 100 Euro /MWh, the feed-in tariffs being clearly the most expensive choice. The public measures that strive for catalyzing market breakthroughs lie in the range 0.1-1 Euro /MWh, but some business driven and procurement type measures could come down to even 0.01 Euro /MWh. The policy costs observed could decrease by 25-60% if accounting for lagging energy impacts. The better policy efficiency of catalytic measures is most likely due to a stronger market and business sensitiveness, understanding of market needs, and focusing more on the end-use sector with active stakeholder involvement. The magnitude of the energy impacts were in average larger from the subsidy instruments but a few end-use technologies linked to catalytic measures reached even higher effects due to the strong market penetration achieved

    Turkish electricity reform has progressed slowly due to internal resistance against privatisation, and gained momentum after Electricity Market Law of 2001, prepared in line with EU Energy Acquis and established required institutional and legal framework. Although the eligibility threshold has reached 39% market opening rate, the dominant position of public both as owner and decision-maker is still the major problem in the sector. Currently Turkey is self-sufficient in electricity, but likely to face shortages in 10 years if the growing demand is not met by either speeding the liberalisation process, or joining the South East Europe Electricity Market.

    Wave energy is the most abundant form of hydrokinetic energy in the United States and wave energy converters (WECs) are being developed to extract the maximum possible power from the prevailing wave climate. However, maximum wave energy capture is currently limited by the narrow banded frequency response of WECs as well as extended protective shutdown requirements during periods of large waves. These limitations must be overcome in order to maximize energy extraction, thus significantly decreasing the cost of wave energy and making it a viable energy source. Techno-economic studies of several WEC devices have shown significant potential to improve wave energy capture efficiency through operational control strategies that incorporate real-time information about local surface wave motions. Integral Consulting Inc., with ARPA-E support, is partnering with Sandia National Laboratories and Spoondrift LLC to develop a coherent array of wave-measuring devices to relay and enable the prediction of wave-resolved surface dynamics at a WEC location ahead of real time. This capability will provide necessary information to optimize power production of WECs through control strategies, thereby allowing for a single WEC design to perform more effectively across a wide range of wave environments.

    2016-01-01

    This paper first examines energy (or fuel) poverty in Japan from 2004 to 2013, especially around the time of the 2011 Great East Japan Earthquake (GEJE). To analyze the issue, the paper employs various poverty and vulnerability measures with the assistance of our unique dataset. The results indicate the aggravation of energy poverty among lower-income and vulnerable households during the past decade, resulting from both the escalation of energy prices and lowering of income. The analysis also employs a new decomposition technique and identifies the explanatory factors associated with the increase in energy poverty. These results suggest there were major changes in the forces driving the increase in energy poverty before and after the GEJE. After 2011, income alleviates energy poverty in Japan, with energy prices becoming the main driving factor. - Highlights: • This study is the first evaluation of energy poverty in Japan by unique microdata. • Focus on the period of the 2011 Great East Japan Earthquake and Fukushima accident. • Shows the aggravation of energy poverty among lower-income and vulnerable households. • Identifies factors accounting for the changes in energy poverty by decomposition. • Major changes in the explanatory factors before and after the Fukushima accident.

    England and Sweden have two of the most advanced systems of universal access to health care in the world. Both have begun major reforms based on similar principles. Universal access and finance from taxation are retained, but a measure of competition between providers of health care is introduced. The reforms therefore show a movement toward the kind of approach advocated by some in the United States. This article traces the origins and early results of the two countries' reform efforts.

    Peveler, WW, Sanders, GJ, Marczinski, CA, and Holmer, B. Effects of energy drinks on economy and cardiovascular measures. J Strength Cond Res 31(4): 882-887, 2017-The use of energy drinks among athletes has risen greatly. Caffeine and taurine are the 2 primary performance enhancing ingredients found in energy drinks. The number of emergency department visits involving energy drinks doubled over the past 5 years. Reviews of the health complications have highlighted adverse cardiovascular events. The literature reveals that caffeine is known to moderately increase blood pressure (BP) and heart rate (HR). The purpose of this study was to determine the effect of 3 different energy drinks on cardiovascular and performance measures. Fifteen recreational runners completed 5 trials. The first trial consisted of a graded exercise protocol. The 4 remaining trials consisted of 15-minute economy trials at a treadmill speed consistent with 70% of subject's V[Combining Dot Above]O2max. An hour before subjects ingested 1 of the 3 energy drinks or a placebo. HR, BP, V[Combining Dot Above]O2, and rating of perceived exertion (RPE) were recorded during the 15-minute trial. Mean values for dependent measures were compared using repeated-measures analysis of variance. Fifteen-minute systolic BP readings were significantly lower in the placebo trials (156.93 ± 15.50) in relation to the 3 energy drink trials (163.87 ± 13.30, 166.47 ± 13.71, and 165.00 ± 15.23). There were no significant differences in diastolic BP and HR. There were no significant differences found in V[Combining Dot Above]O2 or RPE measures. Ingestion of energy drinks demonstrated no change in V[Combining Dot Above]O2 or RPE during the economy trials. The findings show no performance benefits under the conditions of this study. However, there does appear to be a significant increase in systolic BP.

    2010-01-01

    Economic assessments of the welfare effects of energy insecurity are typically uncertain and fail to provide clear guidance to policy makers. As a result, governments have had little analytical support to complement expert judgment in the assessment of energy security. This is likely to be inadequate when considering multiple policy goals, and in particular the intersections between energy security and climate change mitigation policies. This paper presents an alternative approach which focuses on gauging the causes of energy insecurity as a way to assist policy making. The paper focuses on the energy security implications of fossil fuel resource concentration and distinguishes between the price and physical availability components of energy insecurity. It defines two separate indexes: the energy security price index (ESPI), based on the measure of market concentration in competitive fossil fuel markets, and the energy security physical availability index (ESPAI), based on the measure of supply flexibility in regulated markets. The paper illustrates the application of ESPI and ESPAI with two case studies-France and the United Kingdom-looking at the evolution of both indexes to 2030.

  6. Alternatives to the EEG levy. Possible effects of a reform of the energy transition financing on the industry

    2017-01-01

    Although it has been adjusted six times since the year 2000, it has not yet been possible to manage the unrestricted growth of the EEG levy. In the 2017 election year, it becomes therefore ever more obvious that an alternative way to finance the energy transition is high on the political agenda. This would lead to significant changes for energy-intensive companies, regardless of whether they have benefited from a release from the levy or not. At the same time, the alternatives currently discussed have quite different effects on the industrial companies concerned and thereby the industry location Germany. [de

    2014-09-01

    Full Text Available The paper presents concepts and instruments of environmental fiscal reforms (EFR and their application in the Indian context. EFR can lead to environmental improvement more efficiently and cost effectively than traditional regulation. There is substantial experience of successful EFR implementation in the European Union. India has also adopted some EFR measures such as deregulation of petrol prices, coal cess, and subsidy for setting up common effluent treatment plants. The challenges of implementing EFR measures in India are also discussed, including inadequate analysis, policy framework and institutional capacity, as well as conflict with poverty reduction and building political support.

  8. Energy Efficiency Measures to Incorporate into Remodeling Projects

    2014-12-01

    Energy improvements in a home are often approached as one concerted effort, beginning with a simple walk-through assessment or more in-depth energy audit and followed by the installation of recommended energy measures. While this approach allows for systems thinking to guide the efforts, comprehensive energy improvements of this nature are undertaken by a relatively small number of the households in our nation compared to more piecemeal remodeling efforts. Even when programs like the Weatherization Assistance Program and Home Performance with ENERGY STAR are considered, homes that have had a comprehensive energy makeover still represent a small fraction of the 111.1 million households. In this report, the U.S Department of Energy Building America Retrofit Alliance research team looks at the improvement of a home's energy performance in an opportunistic way: it examines what can be done to incorporate energy efficiency measures into general remodeling work and home repair projects. This allows for the possibility for people who would not normally pursue energy efficiency but will remodel their kitchen or re-side their home to improve their home's performance at the same time. There are challenges to this approach, not the least of which being that the work will take place over time in potentially many separate projects. The opportunity to improve a home's energy efficiency at one time expands or contracts with the scope of the remodel. As such, guidance on how to do each piece thoughtfully and with consideration for potential future projects, is critical.

    Graphene produced by chemical vapor deposition (CVD) is a promising candidate for implementing graphene in a range of technologies. In most device configurations, one side of the graphene is supported by a solid substrate, wheras the other side is in contact with a medium of interest, such as a liquid or other two-dimensional material within a van der Waals stack. In such devices, graphene interacts on both faces via noncovalent interactions and therefore surface energies are key parameters for device fabrication and operation. In this work, we directly measured adhesive forces and surface energies of CVD-grown graphene in dry nitrogen, water, and sodium cholate using a modified surface force balance. For this, we fabricated large (∼1 cm 2 ) and clean graphene-coated surfaces with smooth topography at both macro- and nanoscales. By bringing two such surfaces into contact and measuring the force required to separate them, we measured the surface energy of single-layer graphene in dry nitrogen to be 115 ± 4 mJ/m 2 , which was similar to that of few-layer graphene (119 ± 3 mJ/m 2 ). In water and sodium cholate, we measured interfacial energies of 83 ± 7 and 29 ± 6 mJ/m 2 , respectively. Our work provides the first direct measurement of graphene surface energy and is expected to have an impact both on the development of graphene-based devices and contribute to the fundamental understanding of surface interactions.

  10. Exercise, energy expenditure and energy balance, as measured with doubly labelled water.

    2018-02-01

    The doubly labelled water method for the measurement of total daily energy expenditure (TDEE) over 1-3 weeks under daily living conditions is the indicated method to study effects of exercise and extreme environments on energy balance. Subjects consume a measured amount of doubly labelled water (2H2 18O) to increase background enrichment of body water for 18O and 2H, and the subsequent difference in elimination rate between 18O and 2H, as measured in urine, saliva or blood samples, is a measure for carbon dioxide production and thus allows calculation of TDEE. The present review describes research showing that physical activity level (PAL), calculated as TDEE (assessed with doubly labelled water) divided by resting energy expenditure (REE, PAL = TDEE/REE), reaches a maximum value of 2·00-2·40 in subjects with a vigorously active lifestyle. Higher PAL values, while maintaining energy balance, are observed in professional athletes consuming additional energy dense foods to compete at top level. Exercise training can increase TDEE/REE in young adults to a value of 2·00-2·40, when energy intake is unrestricted. Furthermore, the review shows an exercise induced increase in activity energy expenditure can be compensated by a reduction in REE and by a reduction in non-exercise physical activity, especially at a negative energy balance. Additionally, in untrained subjects, an exercise-induced increase in activity energy expenditure is compensated by a training-induced increase in exercise efficiency.

  11. The DHG sum rule measured with medium energy photons

    1997-01-01

    The structure of the nucleon has many important features that are yet to be uncovered. Of current interest is the nucleon spin-structure which can be measured by doing double-polarization experiments with photon beams of medium energies (0.1 to 2 GeV). One such experiment uses dispersion relations, applied to the Compton scattering amplitude, to relate measurement of the total reaction cross section integrated over the incident photon energy to the nucleon anomalous magnetic moment. At present, no single facility spans the entire range of photon energies necessary to test this sum rule. The Laser-Electron Gamma Source (LEGS) facility will measure the double-polarization observables at photon energies between 0.15--0.47 MeV. Either the SPring8 facility, the GRAAL facility (France), or Jefferson Laboratory could make similar measurements at higher photon energies. A high-precision measurement of the spin-polarizability and the Drell-Hearn-Gerasimov sum rule is now possible with the advent of high-polarization solid HD targets at medium energy polarized photon facilities such as LEGS, GRAAL and SPring8. Other facilities with lower polarization in either the photon beam or target (or both) are also pursuing these measurements because of the high priority associated with this physics. The Spin-asymmetry (SASY) detector that will be used at LEGS has been briefly outlined in this paper. The detector efficiencies have been explored with simulations studies using the GEANT software, with the result that both charged and uncharged pions can be detected with a reasonable efficiency (> 30%) over a large solid angle. Tracking with a TPC, which will be built at LEGS over the next few years, will improve the capabilities of these measurements

    Sputtering yields of various wall/limiter materials of fusion devices have been extensively measured in the relevant plasma environment for low-energy light ions (E 14 cm -3 and electron temperature up to 10eV. Target materials used were C (graphite), Ti, Mo, Ta, W, and Fe (stainless steel). In order to study the dependence of the sputtering yields on the incident energy of ions, the target samples were held at negative bias voltage up to 300V. The sputtering yields were determined by a weight-loss method and by spectral line intensity measurements. The data obtained in the present experiment agree well with those previously obtained at the higher energies (E greater than or equal to 200eV) by other authors using different schemes; the present data also extend to substantially lower energies (E approx. > 30eV) than hitherto

    2012-01-01

    The European Union electricity market has been gradually liberalized since 1990s. Theoretically, competitive markets should lead to efficiency gains in the economy thus reducing electricity prices. However, there is a controversial debate about the real effects of the electricity liberalization on electricity prices. Moreover, the increased generation of electricity from renewable energies RES-E (Electricity from Renewable Energy Sources) is also integrated in wholesale market reducing wholesale prices, but the final effect over household prices is not clear. In order to contribute to this debate, this paper provides an empirical investigation into the electricity prices determinants. In fact we develop econometric panel models to explore the relationship between the household electricity prices and variables related to the renewable energy sources and the competition in generation electricity market. More specifically we use a panel data set provided by Eurostat and covering 27 European Union countries during the period 1998–2009. Our results suggest that electricity prices increase with the deployment of RES-E and with the expansion of greenhouse gas emissions produced by energy industries- as a European Union CO 2 emission trading scheme exists. Results also reveal that country's characteristics can affect household electricity prices. -- Highlights: ► Electricity liberalized markets should lead to reduce electricity prices. ► The use of renewable energies (RES) reduce wholesale electricity prices. ► However, household electricity prices are increasing in European Union. ► Panel data models are developed to investigate the effect of RES and electricity competition on household electricity prices. ► We find that the deployment of RES increases prices paid by consumers in a liberalized market.

    A technique for determining π - meson energy by a laminated semiconductor spectrometer is described. Results of experimental test of the technique carried out using beams of meson track of the JINR synchrocyclotron and three Si(Li) detectors are given. A specific feature of the technique is that chi 2 criterium with a functional written through exact thicknesses of semiconductor detectors was used for separating events with disturbance of ionization dependence and determining particle energy. It is shown that the absolute resolution can be not worse than 0.5 MeV in a wide energy range. It is concluded that the technique suggested is suitable for measuring energy of any charged particles with indefinite energy release during stoppage [ru

    ADEME wished to learn about existing effective energy efficiency measures implemented outside of France, whether cross-sectoral or targeted at a specific sector (industry, transport, buildings or agriculture). The objective of this survey was to determine whether any of these measures could be applied in France, with the goal of holding down the growth of energy consumption. This survey has led to the writing of a catalog of 53 two-page fact sheets describing the measures identified as interesting for France. These measures were analysed via classic criteria of evaluation such as cost-efficiency or impact, allowing to highlight the most successful measures for the French territory.

  17. Black hole firewalls require huge energy of measurement

    2014-06-01

    The unitary moving mirror model is one of the best quantum systems for checking the reasoning of the original firewall paradox of Almheiri et al. [J. High Energy Phys. 02 (2013) 062] in quantum black holes. Though the late-time part of radiations emitted from the mirror is fully entangled with the early part, no firewall exists with a deadly, huge average energy flux in this model. This is because the high-energy entanglement structure of the discretized systems in almost maximally entangled states is modified so as to yield the correct description of low-energy effective field theory. Furthermore, the strong subadditivity paradox of firewalls is resolved using nonlocality of general one-particle states and zero-point fluctuation entanglement. Due to the Reeh-Schlieder theorem in quantum field theory, another firewall paradox is inevitably raised with quantum remote measurements in the model. We resolve this paradox from the viewpoint of the energy cost of measurements. No firewall appears, as long as the energy for the measurement is much smaller than the ultraviolet cutoff scale.

  18. Brick industry: Technical and economic assessment of energy saving measures

    Energy Technology Data Exchange (ETDEWEB)

    Florio, G.; Romeo, G. (Calabria Univ., Arcavacata di Rende (Italy). Dipt. di Meccanica)

    Starting from a detailed energy analysis of the production cycle of bricks, the authors make a technical and economic assessment of any possible measure aimed at rationalizing energy. They take energy conservation into consideration not only through the use of exhausted oil residues, but also through the employment of a turboalternator or an internal combustion engine for cogeneration. Both applications of cogeneration prove to be highly interesting from an economic viewpoint even though the turboalternator is put at a disadvantage in competing with internal combustion engines since it increases the overall cogeneration plant costs with respect to the latter.

    2016-01-01

    Oil and gas platforms are energy-intensive systems – each facility uses from a few to several hundreds MW of energy, depending on the petroleum properties, export specifications and field lifetime. Several technologies for increasing the energy efficiency of these plants are investigated in this work. They include: (i) the installation of multiple pressure levels in production manifolds, (ii) the implementation of multiphase expanders, (iii) the promotion of energy and process integration, (iv) the limitation of gas recirculation around the compressors, (v) the exploitation of low-temperature heat from the gas cooling steps, (vi) the downsizing or replacement of the existing gas turbines, and (vii) the use of the waste heat from the power plant. The present study builds on four actual cases located in the North and Norwegian Seas, which differ by the type of oil processed, operating conditions and strategies. The benefits and practical limitations of each measure are discussed based on thermodynamic, economic and environmental factors. Significant energy savings and reductions in CO_2-emissions are depicted, reaching up to 15–20%. However, they strongly differ from one facility to another, which suggests that generic improvements can hardly be proposed, and that thorough techno-economic analyses should be conducted for each plant. - Highlights: • Energy efficiency measures for offshore platforms are assessed. • Energy savings and reductions in CO_2-emissions can reach up to 15-20%. • They differ strongly depending on the oil type, operating conditions and strategies.

    Researchers, university administrators, and faculty members are increasingly interested in measuring and describing instructional practices provided in science, technology, engineering, and mathematics (STEM) courses at the college level. Specifically, there is keen interest in comparing instructional practices between courses, monitoring changes over time, and mapping observed practices to research-based teaching. While increasingly common observation protocols (Reformed Teaching Observation Protocol [RTOP] and Classroom Observation Protocol in Undergraduate STEM [COPUS]) at the postsecondary level help achieve some of these goals, they also suffer from weaknesses that limit their applicability. In this study, we leverage the strengths of these protocols to provide an easy method that enables the reliable and valid characterization of instructional practices. This method was developed empirically via a cluster analysis using observations of 269 individual class periods, corresponding to 73 different faculty members, 28 different research-intensive institutions, and various STEM disciplines. Ten clusters, called COPUS profiles, emerged from this analysis; they represent the most common types of instructional practices enacted in the classrooms observed for this study. RTOP scores were used to validate the alignment of the 10 COPUS profiles with reformed teaching. Herein, we present a detailed description of the cluster analysis method, the COPUS profiles, and the distribution of the COPUS profiles across various STEM courses at research-intensive universities. © 2015 T.

    1994-12-31

    The failure of both democracies and revolutions in Latin America is due to the fact that the State has been trusted with political, economic and social organization, instead of relying on the motivations and capabilities of intermediate associations and the individual members of society. Therefore, the process of change is not just a matter of national decision; it is something that must, and will, take place. Ecuador understands perfectly well the need for reform. Major laws have already been enacted, and a bill for modernization of the State is currently under consideration by congress. The concept of modernization and, therefore, change does not merely imply new laws, simplified procedures or easier operations; it basically means allowing the creative forces of individuals, enterprises and intermediate associations to play a more influential role. As in other Latin American countries, in Ecuador there can be no real modernization, no real change in society without a major revolution in energy and telecommunications. Thus, two important laws have been drafted to demonopolize petroleum and electric power operations and open them up both to national and foreign private sector participation.

  3. Precision cosmological measurements: Independent evidence for dark energy

    2008-01-01

    Using recent precision measurements of cosmological parameters, we re-examine whether these observations alone, independent of type Ia supernova surveys, are sufficient to imply the existence of dark energy. We find that best measurements of the age of the Universe t 0 , the Hubble parameter H 0 and the matter fraction Ω m strongly favor an equation of state defined by (w<-1/3). This result is consistent with the existence of a repulsive, acceleration-causing component of energy if the Universe is nearly flat

  4. On the energy pattern factor in wind measurements

    1977-01-01

    Measurements of energy pattern factor K/sub e/ were made using a continuous-analogue wind-power metering technique, rather than by the more usual sampling procedure. The values obtained were significantly larger than the usually accepted figure. The discrepancy is attributed partly to the method of measurement, which includes the actual power present rather than the amount that can be extracted, and partly to the use of rather more typical wind speeds. It is concluded, however, that more energy can be derived from wind schemes than was thought, even during periods of light wind. These conclusions improve the viability of wind power plants.

    The paper first discusses the energy accuracy of the BILL conversion electron spectrometer at the Grenoble high flux reactor. With an improved temperature stabilisation of the magnets, an energy accuracy of ΔE/E -5 can be reached. After this, highly exact measurements of high-energy conversion electron lines of the 200 Hg, 114 Cd, 165 Dy, 168 Er, 239 U nuclei and the 13 C, 28 Al 3 H and 92 Zr photoelectron lines were carried out. Energy calibration of the spectrometer was carried out in the 1.5 MeV to 6.5 MeV range with intensive high-energy transitions of the 200 Hg nucleus. Systematic calibration errors could be investigated by means of combinations between the calibration lines. A calibration for absolute energies was obtained by comparing low-energy gamma transitions of 200 Hg with the 411.8 keV gold standard. (orig.) [de

    As for the pressure measurement in atomic energy industry, it is mostly the measurement using differential pressure transmitters and pressure transmitters for process measurement with the general accuracy of measurement of 0.2 - 0.5 % FS/year. However, recently for the development of nuclear fusion reactors and the establishment of nuclear fuel cycle accompanying new atomic energy technology, there are the needs of the pressure measurement having higher accuracy of 0.01 % FS/year and high resolution, and quartz vibration type pressure sensors appeared. New high accuracy pressure measurement techniques were developed by the advance of data processing and the rationalization of data transmission. As the results, the measurement of the differential pressure of helium-lithium two-phase flow in the cooling system of nuclear fusion reactors, the high accuracy measuring system for the level of plutonium nitrate and other fuel substance in tanks in fuel reprocessing and conversion, the high accuracy measurement of atmospheric pressure and wind velocity in ducts, chimneys and tunnels in nuclear facilities and so on became feasible. The principle and the measured data of quartz vibration type pressure sensors are shown. (Kako, I.)

    Measurement Methods for Assessing Contaminant Levels in Captured CO2 Streams; (3) An Assessment of Current Commercial Scale Fisher-Tropsch (F-T) Technologies for the Conversion of Syngas to Fuels; (4) An Overview of CO2 Capture Technologies from Various Industrial Sources; and (5) Lifecycle Analysis for the Capture and Conversion of CO2 to Synthetic Diesel Fuel. Commercial scale Sunexus CO2 Solar Reformer plant designs, proposed in this report, should be able to utilize waste CO2 from a wide variety of industrial sources to produce a directly usable synthetic diesel fuel that replaces petroleum derived fuel, thus improving the United States energy security while also sequestering CO2. Our material balance model shows that every 5.0 lbs of CO2 is transformed using solar energy into 6.26 lbs (1.0 U.S. gallon) of diesel fuel and into by-products, which includes water. Details are provided in the mass and energy model in this report.

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

    Grossman, Andrew James

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

    1983-12-01

    We have measured the inclusive deep inelastic scattering of muons on nucleons in iron using beams of 93 and 215 GeV muons. To perform this measurement, we have built and operated the Multimuon Spectrometer (MMS) in the muon beam at Fermilab. The MMS is a magnetized iron target/spectrometer/calorimeter which provides 5.61 kg/cm 2 of target, 9% momentum resolution on scattered muons, and a direct measure of total hadronic energy with resolution sigma/sub nu/ = 1.4√nu(GeV). In the distributed target, the average beam energies at the interaction are 88.0 and 209 GeV. Using the known form of the radiatively-corrected electromagnetic cross section, we extract the structure function F 2 (x,Q 2 ) with a typical precision of 2% over the range 5 2 2 /c 2 . We compare our measurements to the predictions of lowest order quantum chromodynamics (QCD) and find a best fit value of the QCD scale parameter Λ/sub LO/ = 230 +- 40/sup stat/ +- 80/sup syst/ MeV/c, assuming R = 0 and without applying Fermi motion corrections. Comparing the cross sections at the two beam energies, we measure R = -0.06 +- 0.06/sup stat/ +- 0.11/sup syst/. Our measurements show qualitative agreement with QCD, but quantitative comparison is hampered by phenomenological uncertainties. The experimental situation is quite good, with substantial agreement between our measurements and those of others. 86 references

    1996-01-01

    An environmental tax reform is seen by many as a possible solution to some crucial problems of modern society - pollution, excessive resource consumption and unemployment. Changes in the system of taxation are here seen as a long term process, one that must cheapen the costs of labour and make the costs of resource use more expensive - a process which can also create major changes in our society as to conceptions of quality, work, consumption etc. The conference presented proposals for an ecological tax and duty system that would contribute to: Changing technology so that it becomes more resource and energy effective. Changing the economic mechanisms so that resource consumption and pollution become more expensive while human resources become cheaper. Changing personal life styles and values so that material consumption becomes less decisive for our choices and priorities. An environmental tax reform is neither without problems nor painless. An economy and an industrial sector based on increasing consumption of energy and raw materials will, in the long run, lead to drawbacks that far outweigh those that are connected with an economic re-orientation whose driving force is another conception of nature.

    Environmental concerns and rising fossil fuel prices have prompted rapid development in the renewable energy sector. Wind energy, in particular, has become increasingly popular in the United States. However, the intermittency of available wind energy makes it difficult to integrate wind energy into the power grid. Thus, the expansion and successful implementation of wind energy requires accurate wind resource assessments and wind power forecasts. The actual power produced by a turbine is affected by the wind speeds and turbulence levels experienced across the turbine rotor disk. Because of the range of measurement heights required for wind power estimation, remote sensing devices (e.g., lidar) are ideally suited for these purposes. However, the volume averaging inherent in remote sensing technology produces turbulence estimates that are different from those estimated by a sonic anemometer mounted on a standard meteorological tower. In addition, most lidars intended for wind energy purposes utilize a standard Doppler beam-swinging or Velocity-Azimuth Display technique to estimate the three-dimensional wind vector. These scanning strategies are ideal for measuring mean wind speeds but are likely inadequate for measuring turbulence. In order to examine the impact of different lidar scanning strategies on turbulence measurements, a WindCube lidar, a scanning Halo lidar, and a scanning Galion lidar were deployed at the Southern Great Plains Atmospheric Radiation Measurement (ARM) site in Summer 2013. Existing instrumentation at the ARM site, including a 60-m meteorological tower and an additional scanning Halo lidar, were used in conjunction with the deployed lidars to evaluate several user-defined scanning strategies. For part of the experiment, all three scanning lidars were pointed at approximately the same point in space and a tri-Doppler analysis was completed to calculate the three-dimensional wind vector every 1 second. In another part of the experiment, one of

    A uranium thermometer has been designed and built in order to make local power measurements in the First Energy Amplifier Test (FEAT). Due to the experimental conditions power measurements of tens to hundreds of nW were required, implying a sensitivity in the temperature change measurements of the order of 1 mK. A uranium thermometer accurate enough to match that sensitivity has been built. The thermometer is able to determine the absolute energetic gain obtained in a tiny subcritical uranium assembly exposed to a proton beam of kinetic energies between 600 MeV and 2.75 GeV. In addition, the thermometer measurements have provided information about the spatial power distribution and the shape of the neutron spallation cascade.

    Fulfilling the Commitments on UN FCCC through the U.S. Country Studies Program, Kazakstan has developed the national GHG Inventory, vulnerability and adaptation assessment and estimated the possibility of mitigation measures in certain sectors. Next step is developing National Climate Change Action Plan. That process includes such major steps as setting priorities in mitigation measures and technologies, their comprehensive evaluation, preparation implementation strategies, developing the procedure of incorporation of the National Action Plan into other development plans and programs. This paper presents programs and measures that can reduce GHG emissions in non-energy sector. Measures in land-use change and forestry, agriculture and coal mining are considered. Current situation in non-energy sector of Kazakstan is discussed. The amount of GHG emissions reduction and cost analysis presented in this paper was developed with the use of IPCC recommendations.

    Full Text Available The results of power quality measurements, obtained during an energy audit in the heating plant Vreoci in the Electric Power System of Serbia, are presented in the paper. Two steam boilers, rated at 120MW each, are installed in this heating plant, using coal as a fuel. The energy audit encompassed the measurements of the complete set of parameters needed to determine the thermal efficacy of boilers and the entire heating plant. Based on the measurement results, several technical measures for improving energy efficiency of the plant are proposed. The measures evaluated in the paper should contribute to the reduction of fossil fuel usage and CO2 emissions, thereby resulting in a significant impact in both financial and ecological areas.

  17. A Method to Measure the Bracelet Based on Feature Energy

    2017-12-01

    To measure the bracelet automatically, a novel method based on feature energy is proposed. Firstly, the morphological method is utilized to preprocess the image, and the contour consisting of a concentric circle is extracted. Then, a feature energy function, which is relevant to the distances from one pixel to the edge points, is defined taking into account the geometric properties of the concentric circle. The input image is subsequently transformed to the feature energy distribution map (FEDM) by computing the feature energy of each pixel. The center of the concentric circle is thus located by detecting the maximum on the FEDM; meanwhile, the radii of the concentric circle are determined according to the feature energy function of the center pixel. Finally, with the use of a calibration template, the internal diameter and thickness of the bracelet are measured. The experimental results show that the proposed method can measure the true sizes of the bracelet accurately with the simplicity, directness and robustness compared to the existing methods.

    1976-03-01

    Experimental measurements have been made of the energy spectra of neutrons transmitted through slabs of iron, lead and perspex for incident neutron energies of 0.5, 1.0, 1.5 and 1.8 MeV. The neutron energy measurements were made using a He-3 spectrometer. The dependence of the neutrons energy spectrum as a function of scattering thickness was determined. The neutrons source used was a 3MeV Van de Graaff accelerator with a tritium target using the H 3 (p,n) He 3 reaction. The results obtained by the investigator on energy dependence of transmitted neutrons as a function of thickness of scattering material were compared, where possible, with the results obtained by other workers. The comparisons indicated good agreement. The experiment's results are compared with MORSE Monte Carlo calculated values. It is worthwhile to note that direct comparison between measured cross section values and the recommended ones are very far from satisfactory. In almost all cases the calculated spectrum is harder than the experimental one, a situation common to the penetrating and the back-scattered flux

    This paper provides an analysis of the current energy usage (net energy and final energy by fuels) and associated carbon dioxide (CO 2 ) emissions of the Swedish residential building stock, which includes single-family dwellings and multi-family dwellings. Twelve energy saving measures (ESMs) are assessed using a bottom–up modeling methodology, in which the Swedish residential stock is represented by a sample of 1400 buildings (based on data from the year 2005). Application of the ESMs studied gives a maximum technical reduction potential in energy demand of 53%, corresponding to a 63% reduction in CO 2 emissions. Although application of the investigated ESMs would reduce CO 2 emissions, the measures that reduce electricity consumption for lighting and appliances (LA) will increase CO 2 emissions, since the saved electricity production is less CO 2 -intensive than the fuel mix used for the increased space heating required to make up for the loss in indirect heating obtained from LA. - Highlights: ► Analysis of year 2005energy use and CO2 emissions of Swedish residential buildings. ► Includes all single-family dwellings and multi-family dwellings. ► Bottom–up modeling of building stock represented by 1400 buildings. ► Technical effects of 12 energy saving measures are assessed. ► Energy demand can be reduced by53% and associated CO 2 emissions by 63%

    The measured energy savings resulting from using night temperature setback in typical light-construction wooden office buildings was determined. Researchers installed monitoring equipment in a six-building sample of two-story wooden buildings at Fort Devens, Massachusetts. Data obtained during both single-setting and night-setback operating modes were used to develop models of each building's heat consumption as a function of the difference between inside and outside temperature. These models were used to estimate seasonal savings that could be obtained from the use of night-setback thermostat control. The measured savings in heating energy from using night temperature setback for the six Fort Devens buildings ranged from 14% to 25%; the mean savings was 19.2%. Based on an energy cost of $0.65/therm of natural gas, the estimated average cost savings of using automatic setback thermostats in these buildings is $780 per year per building

    As one of the biggest parts of total national energy consumption (TNEC), building energy consumption (BEC) catches public eyes and has been regarded as a crucial problem of the current society. For the past 20 years, BEC in china has been increasing at a high speed. To curb the rapid growing of BEC, china has enforced and implemented a series of policies. These include enforcing BEC constraints on new building projects, promoting more environment friendly building designs, establishing a more sophisticated legislation for building energy conservation, and increasing the total budget in the area of BEC control. This article analyzed china BEC situation and the challenges. As the main point, the measures required by China government to improve building energy efficiency were introduced as well.

    1990-01-01

    The role of fracture-velocity, microstructure, and fracture-energy barriers in elastic wave radiation during a dynamic fracture was investigated in experiments in which dynamic tensile cracks of two fracture cofigurations of double cantilever beam geometry were propagating in glass samples. The first, referred to as primary fracture, consisted of fractures of intact glass specimens; the second configuration, referred to as secondary fracture, consisted of a refracture of primary fracture specimens which were rebonded with an intermittent pattern of adhesive to produce variations in fracture surface energy along the crack path. For primary fracture cases, measurable elastic waves were generated in 31 percent of the 16 fracture events observed; the condition for radiation of measurable waves appears to be a local abrupt change in the fracture path direction, such as occurs when the fracture intersects a surface flaw. For secondary fractures, 100 percent of events showed measurable elastic waves; in these fractures, the ratio of radiated elastic wave energy in the measured component to fracture surface energy was 10 times greater than for primary fracture.

    The microscopic spatial distribution of energy deposition in irradiated tissue plays a significant role in the final biological effect produced. Therefore, it is important to have accurate microdosimetric spectra of radiation fields used for radiobiology and radiotherapy. The experiments desribed here were designed to measure the distributions of energy deposition around high energy heavy ion tracks generated at Lawrence Berkeley Laboratory's Bevalac Biomedical Facility. A small proportional counter mounted in a large (0.6 by 2.5 m) vacuum chamber was used to measure energy deposition distributions as a function of the distance between detector and primary ion track. The microdosimetric distributions for a homogeneous radiation field were then calculated by integrating over radial distance.

    This article provides a synthesized, workable framework for analyzing national energy security policies and performance. Drawn from research interviews, survey results, a focused workshop, and an extensive literature review, this article proposes that energy security ought to be comprised of five dimensions related to availability, affordability, technology development, sustainability, and regulation. We then break these five dimensions down into 20 components related to security of supply and production, dependency, and diversification for availability; price stability, access and equity, decentralization, and low prices for affordability; innovation and research, safety and reliability, resilience, energy efficiency, and investment for technology development; land use, water, climate change, and air pollution for sustainability; and governance, trade, competition, and knowledge for sound regulation. Further still, our synthesis lists 320 simple indicators and 52 complex indicators that policymakers and scholars can use to analyze, measure, track, and compare national performance on energy security. The article concludes by offering implications for energy policy more broadly. -- Highlights: → Energy security should consist of five dimensions related to availability, affordability, technology development, sustainability, and regulation. → The dimensions of energy security can be broken down into 20 components. → These components can be distilled into 320 simple indicators and 52 complex indicators.

    2015-11-01

    Full Text Available In the ten years since committing to clean energy transition, China has formulated a large number of policies and programs to achieve some very ambitious targets. This paper argues that the dearth of empirical studies concerning the implementation of these new policies and programs has created a knowledge gap between official policy documents, which are vague and lacking in specifics, and official policy outcomes, which are unreliable. In particular, the merits and limitations of flexible implementation with regard to desirable outcomes need to be debated and clarified. This paper calls for more empirical investigation in four areas as a starting point: (1 the nature and extent of flexibility in the implementation; (2 implementation strategies and their impacts; (3 factors that shape the behavior of local officials responsible for implementation; and (4 the relationship between the central-local relation and policy implementation.

    Many countries are facing a challenging transition toward more sustainable energy systems, which produce more renewables and consume less energy. The latter goal can only be achieved through a combination of efficiency measures and changes in people’s lifestyles and routine behaviors (i.e., sufficiency). While research has shown that acceptance of technical efficiency is relatively high, there is a lack of research on societal preferences for sufficiency measures. However, this is an important prerequisite for designing successful interventions to change behavior. This paper analyses societal preferences for different energy-related behaviors in Switzerland. We use an online choice-based conjoint analysis (N = 150) to examine preferences for behaviors with high technical potentials for energy demand reduction in the following domains: mobility, heating, and food. Each domain comprises different attributes across three levels of sufficiency. Respondents were confronted with trade-off situations evoked through different fictional lifestyles that comprised different combinations of attribute levels. Through a series of trade-off decisions, participants were asked to choose their preferred lifestyle. The results revealed that a vegetarian diet was considered the most critical issue that respondents were unwilling to trade off, followed by distance to workplace and means of transportation. The highest willingness to trade off was found for adjustments in room temperature, holiday travel behaviors, and living space. Participants’ preferences for the most energy-sufficient lifestyles were rather low. However, the study showed that there were lifestyles with substantive energy-saving potentials that were well accepted among respondents. Our study results suggest that the success of energy-sufficiency interventions might depend strongly on the targeted behavior. We speculate that they may face strong resistance (e.g., vegetarian diet). Thus, it seems promising to

    Constraints on dark energy from current observational data are sensitive to how distances are measured from Type Ia supernova (SN Ia) data. We find that flux averaging of SNe Ia can be used to test the presence of unknown systematic uncertainties, and yield more robust distance measurements from SNe Ia. We have applied this approach to the nearby+SDSS+ESSENCE+SNLS+HST set of 288 SNe Ia, and the 'Constitution' set of 397 SNe Ia. Combining the SN Ia data with cosmic microwave background anisotropy data from Wilkinson Microwave Anisotropy Probe 5 yr observations, the Sloan Digital Sky Survey baryon acoustic oscillation measurements, the data of 69 gamma-ray bursts (GRBs) , and the Hubble constant measurement from the Hubble Space Telescope project SHOES, we measure the dark energy density function X(z)≡ρ X (z)/ρ X (0) as a free function of redshift (assumed to be a constant at z>1 or z>1.5). Without the flux averaging of SNe Ia, the combined data using the Constitution set of SNe Ia seem to indicate a deviation from a cosmological constant at ∼95% confidence level at 0 98% confidence level for z≤0.75 using the combined data with 288 SNe Ia from nearby+SDSS+ESSENCE+SNLS+HST, independent of the assumptions about X(z≥1). We quantify dark energy constraints without assuming a flat Universe using the dark energy figure of merit for both X(z) and a dark energy equation-of-state linear in the cosmic scale factor.

    The report describes measurements performed for the energy calibration of the TANSY neutron detectors (two arrays of 16 detectors each one). The calibration procedure determines four calibration parameters for each detector. Results of the calibration measurements are given and test measurements are presented. A relation of the neutron detector calibration parameters to producer's data for the photomulipliers is analysed. Also the tests necessary during normal operation of the TANSY neutron spectrometer are elaborated (passive and active tests). A method how to quickly get the calibration parameters for a spare detector in an array of the neutron detectors is included

    Chromaticity is one of the important parameters of circular accelerators and plays crucial role in its operation. In Indus-2 storage ring the natural chromaticity is -19 and -12 in horizontal and vertical planes respectively. For the good injection at 550 MeV in Indus-2, chromaticity needs to be kept at (+1, +1). The corrected chromaticity does not remain constant during the energy ramp up to 2.5 GeV. We measured Indus-2 storage ring chromaticity by the conventional RF frequency change method. The measurement method and the result of the measurement are reported in this paper. (author)

  17. The location as an energy efficiency and renewable energy supply measure for data centres in Europe

    Depoorter, Victor; Oró, Eduard; Salom, Jaume

    2015-01-01

    Highlights: • A data centre energy model was developed using TRNSYS. • The potential of direct air free cooling integration was evaluated around Europe. • A set of energy indicators describing the operation of data centres were defined. • The location of a data centre could significantly affect its operation and impact. • Smart management of the IT load can reduce energy consumption and CO 2 emission. - Abstract: The massive data centre energy consumption has motivated significant efforts to use energy efficiency strategies and the implementation of renewable energy sources that reduce their operational costs and environmental impact. Considering that the potential of many of these measures is often closely linked to the climate conditions, the location of data centres can have a major impact on their energy demand. Moreover, from a holistic approach, differences among regions become even more important when accounting for the electricity attributes from the grid. To assess these differences this work compares by the use of energy indicators the behaviour of a data centre located at different representative emplacements in Europe. To do so, a dynamic energy model which incorporates free cooling strategy and photovoltaic energy is developed. The paper concludes by suggesting that future data centre developments could consider site selection as a new strategy to limit the environmental impact attributable to this sector

  18. Measuring and improving the public perceptions on nuclear energy

    International Nuclear Information System (INIS)

    Choi, Young Sung

    2001-01-01

    The purpose of this paper is to measure the public's perception on risk and benefit of nuclear power and to find ways to improve the perceptions. Latent Class Analysis is adopted for the perception measures, which quantify people's perception and reveal the perception structure. The measures resulted from Latent Class Analysis show that women perceive risks to be more existent and benefits to be less than men do. Moreover there is a tendency that if education level is high, perceived risk is low and perceived benefit is high. The perception of risk and benefit also depends on different channels through which people get information about nuclear energy. Comparing seven different information channels, the most effective ways of communicating with people to improve the risk and benefit perception of nuclear energy are found to be the visit to nuclear plants and the education through the regular schooling. Information dissemination through mass media is only effective to the benefit perception

    A beam energy measurement system employing a set of capacitive probes has been developed at NIRS-930 cyclotron. Principle of the measurement is applying a modified-TOF method, so that the two proves are installed at one of the straight section in the beam transport line. Usually they are separated about 5.8 m, which is equivalent to the almost final path length of the beam extracted in the cyclotron. In the measurement, two beam signals are superimposed by adjusting a position of the downstream-probe along the beam direction with watching an oscilloscope screen roughly. In order to determine the beam energy accurately the signals are processed by MCA with suitable electric module. (author)

    Smart metering and smart grid are incoming technologies that provide new opportunities in various fields. In connection with the issue of evaluation of the energy aspects of public lighting networks opens up the possibility of evaluating and measuring consumption. Based on the obtained values would be possible to determine energy consumption of lighting systems. This obtained value could serve as a basis for comparing the relevant networks and thus the optimality assessment of lighting designs. Currently, the measure placed in the switchboard of public lighting. If we have considered sections parametramim same lighting, it is necessary to obtain more value from the measured or determined to assess the consumption of time. Proposal of such methods is still under construction but the basic methods have already been outlined. (Authors)

  2. Considering fluctuation energy as a measure of gyrokinetic turbulence

    International Nuclear Information System (INIS)

    Plunk, G G; Tatsuno, T; Dorland, W

    2012-01-01

    In gyrokinetic theory, there are two quadratic measures of fluctuation energy, left invariant under nonlinear interactions, that constrain turbulence. In a recent work (Plunk and Tatsuno 2011 Phys. Rev. Lett. 106 165003) we reported on the novel consequences that this constraint has for the direction and locality of spectral energy transfer. This paper builds on that previous work. We provide a detailed analysis in support of the results of Plunk and Tatsuno (2011 Phys. Rev. Lett. 106 165003), but significantly broaden the scope and use additional methods to address the problem of energy transfer. The perspective taken here is that the fluctuation energies are not merely formal invariants of an idealized model (two-dimensional gyrokinetics (Plunk et al 2010 J. Fluid Mech. 664 407–35)) but also general measures of gyrokinetic turbulence, i.e. quantities that can be used to predict the behavior of turbulence. Although many questions remain open, this paper collects evidence in favor of this perspective by demonstrating in several contexts that constrained spectral energy transfer governs the dynamics.

    The energy spectrum of protons accelerated from the rear-side of a thin foil illuminated with ultra-intense laser light from the OMEGA EP laser system at the University of Rochester's Laboratory for Laser Energetics (LLE) was measured using a stack of radiochromic film (RCF). The film stack consisted of four layers of Gafchromic HD-V2 film and four layers of Gafchromic MD-V2-55 film. Aluminum foils of various thicknesses were placed between each piece of RCF in the stack. This arrangement allowed protons with energies of 30 MeV to reach the back layer of RCF in the stack. The stack was placed in the detector plane of a Thomson parabola ion energy (TPIE) spectrometer. Each piece of film in the stack was scanned using a commercially available flat-bed scanner (Epson 10000XL). The resulting optical density was converted into proton fluence using an absolute calibration of the RCF obtained at the SUNY Geneseo 1.7 MV Pelletron accelerator laboratory. In these calibration measurements, the sensitivity of the radiochromic film was measured using monoenergetic protons produced by the accelerator. Details of the analysis procedure and the resulting proton energy spectra will be presented. Funded in part by a grant from the DOE through the Laboratory for Laser Energetics.

  6. Free energy surfaces from nonequilibrium processes without work measurement

    Adib, Artur B.

    2006-04-01

    Recent developments in statistical mechanics have allowed the estimation of equilibrium free energies from the statistics of work measurements during processes that drive the system out of equilibrium. Here a different class of processes is considered, wherein the system is prepared and released from a nonequilibrium state, and no external work is involved during its observation. For such "clamp-and-release" processes, a simple strategy for the estimation of equilibrium free energies is offered. The method is illustrated with numerical simulations and analyzed in the context of tethered single-molecule experiments.

  11. Measurement of the nucleon structure function using high energy muons

    Energy Technology Data Exchange (ETDEWEB)

    Meyers, P.D.

    1983-12-01

    We have measured the inclusive deep inelastic scattering of muons on nucleons in iron using beams of 93 and 215 GeV muons. To perform this measurement, we have built and operated the Multimuon Spectrometer (MMS) in the muon beam at Fermilab. The MMS is a magnetized iron target/spectrometer/calorimeter which provides 5.61 kg/cm/sup 2/ of target, 9% momentum resolution on scattered muons, and a direct measure of total hadronic energy with resolution sigma/sub nu/ = 1.4..sqrt..nu(GeV). In the distributed target, the average beam energies at the interaction are 88.0 and 209 GeV. Using the known form of the radiatively-corrected electromagnetic cross section, we extract the structure function F/sub 2/(x,Q/sup 2/) with a typical precision of 2% over the range 5 < Q/sup 2/ < 200 GeV/sup 2//c/sup 2/. We compare our measurements to the predictions of lowest order quantum chromodynamics (QCD) and find a best fit value of the QCD scale parameter ..lambda../sub LO/ = 230 +- 40/sup stat/ +- 80/sup syst/ MeV/c, assuming R = 0 and without applying Fermi motion corrections. Comparing the cross sections at the two beam energies, we measure R = -0.06 +- 0.06/sup stat/ +- 0.11/sup syst/. Our measurements show qualitative agreement with QCD, but quantitative comparison is hampered by phenomenological uncertainties. The experimental situation is quite good, with substantial agreement between our measurements and those of others. 86 references.

    Epstein, M.

    1997-01-01

    Methane forming reactions using either steam or CO 2 have been known to industry for a long time. These endothermic reactions require the investment of a relatively large amount of energy. German researchers, in the 1970's, conceived and developed the idea to use this reaction and the reverse methanation reaction in a closed loop for the transportation and distribution of nuclear heat. The idea was also adopted for use with solar energy as a heat source. Utilizing solar energy as the heat source, the Weismann Institute of Science has fabricated, installed and operated a complete loop capable of the conversion and transportation of over 400 kW of heat. This system can be operated with a wide range of CO 2 /H 2 O/CH 4 feed mixtures. Steam reforming is the common reforming reaction in the ''open loop'' mode for the purpose of synthesis gas production. This is accomplished with a large excess of steam on a nickel catalyst. However, it has only recently been recognized that there is also a substantial market for CO 2 reforming. The CO 2 /CH 4 mixture in various proportions exists in many places and has, so far, not been used efficiently. The sources for this mixture are biogas produced in anaerobic digestion processes and gas resources such as the NATUNA gas field in Indonesia, and many others. Therefore, the system of CO 2 /CH 4 deserves more attention. Commercial catalysts used for steam reforming based on nickel are not suitable for this system. Therefore, other catalysts based on Rhodium and Ruthenium have been developed and some performance data is presented in this paper. Also presented is a conceptual schematic layout of a CO 2 reforming plant and matching methanator. A computer code for a detailed design of the entire loop in a commercial size system has been prepared where optimized operational conditions as well as equipment parameters can be determined.

    2015-11-01

    The ``Living Bridge'' project plans to install a tidal turbine at Memorial Bridge in the Piscataqua River at Portsmouth, NH. A spatio-temporal tidal energy resource assessment was performed using long term bottom-deployed Acoustic Doppler Current Profilers ADCP. Two locations were evaluated: at the planned deployment location and mid-channel. The goal was to determine the amount of available kinetic energy that can be converted into usable electrical energy on the bridge. Changes in available kinetic energy with ebb/flood and spring/neap tidal cycles and electrical energy demand were analyzed. A system model is used to calculate the net energy savings using various tidal generator and battery bank configurations. Differences in the tidal characteristics between the two measurement locations are highlighted. Different resource evaluation methodologies were also analyzed, e.g., using a representative ADCP ``bin'' vs. a more refined, turbine-geometry-specific methodology, and using static bin height vs. bin height that move w.r.t. the free surface throughout a tidal cycle (representative of a bottom-fixed or floating turbine deployment, respectively). ADCP operating frequencies and bin sizes affect the standard deviation of measurements, and measurement uncertainties are evaluated. Supported by NSF-IIP grant 1430260.

  17. Possible Measurable Effects of Dark Energy in Rotating Superconductors

    Directory of Open Access Journals (Sweden)

    Clovis Jacinto de Matos

    2009-01-01

    Full Text Available We discuss recent laboratory experiments with rotating superconductors and show that three so far unexplained experimentally observed effects (anomalous acceleration signals, anomalous gyroscope signals, Cooper pair mass excess can be physically explained in terms of a possible interaction of dark energy with Cooper pairs. Our approach is based on a Ginzburg-Landau-like model of electromagnetic dark energy, where gravitationally active photons obtain mass in the superconductor. We show that this model can account simultaneously for the anomalous acceleration and anomalous gravitomagnetic fields around rotating superconductors measured by Tajmar et al. and for the anomalous Cooper pair mass in superconductive Niobium, measured by Cabrera and Tate. It is argued that these three different physical effects are ultimately different experimental manifestations of the simultaneous spontaneous breaking of gauge invariance and of the principle of general covariance in superconductive materials.

    2018-07-01

    The development of the next generation of ultra-low energy antiproton and ion facilities requires precise information about the beam emittance to guarantee optimum performance. In the Extra-Low ENergy Antiproton storage ring (ELENA) the transverse emittances will be measured by scraping. However, this diagnostic measurement faces several challenges: non-zero dispersion, non-Gaussian beam distributions due to effects of the electron cooler and various systematic errors such as closed orbit offsets and inaccurate rms momentum spread estimation. In addition, diffusion processes, such as intra-beam scattering might lead to emittance overestimates. Here, we present algorithms to efficiently address the emittance reconstruction in presence of the above effects, and present simulation results for the case of ELENA.

    1987-08-01

    Because some workers have a high potential for significant neutron exposure, the Savannah River Plant (SRP) contracted with Pacific Northwest Laboratory (PNL) to verify the accuracy of neutron dosimetry at the plant. Energy spectrum and neutron dose measurements were made at the SRP calibrations laboratory and at several other locations. The energy spectra measurements were made using multisphere or Bonner sphere spectrometers, 3 He spectrometers, and NE-213 liquid scintillator spectrometers. Neutron dose equivalent determinations were made using these instruments and others specifically designed to determine dose equivalent, such as the tissue equivalent proportional counter (TEPC). Survey instruments, such as the Eberline PNR-4, and the thermoluminescent dosimeter (TLD)-albedo and track etch dosimeters (TEDs) were also used. The TEPC, subjectively judged to provide the most accurate estimation of true dose equivalent, was used as the reference for comparison with other devices. 29 refs., 43 figs., 13 tabs

    This paper documents the measurement equipment in a low-energy house in Sisimiut, Greenland. Detailed measurements are being taken on energy consumption, indoor temperatures, floor heating, ventilation, open/closed state of doors and windows, and indoors climate. Equipped with a central control unit, experiments can be designed in order to study heat dynamics of the building. It is described how to plan and execute such experiments in one apartment in the building. The building also features both a solar thermal system and extra buffer tank facilitating testing of storage strategies on the power generated by the solar thermal system. A weather station equipped with thermometer, pyranometer and anemometer is installed on the building as well. Finally, it is described how to retrieve data from an SQL server which is configured to take monthly backups. R functions have been implemented to fetch and prepare the data for time series analysis. Examples are given on the use of these. (Author)

  1. An Energy-Based Similarity Measure for Time Series

    2007-11-01

    Full Text Available A new similarity measure, called SimilB, for time series analysis, based on the cross-ΨB-energy operator (2004, is introduced. ΨB is a nonlinear measure which quantifies the interaction between two time series. Compared to Euclidean distance (ED or the Pearson correlation coefficient (CC, SimilB includes the temporal information and relative changes of the time series using the first and second derivatives of the time series. SimilB is well suited for both nonstationary and stationary time series and particularly those presenting discontinuities. Some new properties of ΨB are presented. Particularly, we show that ΨB as similarity measure is robust to both scale and time shift. SimilB is illustrated with synthetic time series and an artificial dataset and compared to the CC and the ED measures.

    In November of 1982 work was begun in collaboration with Columbia University and Lawrence Berkeley Laboratory to use microdosimetric methods to measure energy deposition of heavy ions produced at LBL's Bevalac Biomedical Facility. Last year the authors reported preliminary results indicating that secondary charged particle equilibrium was probably obtained using this experimental setup, but that there seemed to be poor spatial resolution in the solid state position-sensitive detector. Further analysis of the measurements taken in August 1983 shows that because of this electronic noise in the position-sensitive detector, only the 56 Fe data yielded useful microdosimetric spectra

  3. Measures of International Manufacturing and Trade of Clean Energy Technologies

    2017-05-25

    The technologies that produce clean energy, such as solar photovoltaic panels and lithium ion batteries for electric vehicles, are globally manufactured and traded. As demand and deployment of these technologies grows exponentially, the innovation to reach significant economies of scale and drive down energy production costs becomes less in the technology and more in the manufacturing of the technology. Manufacturing innovations and other manufacturing decisions can reduce costs of labor, materials, equipment, operating costs, and transportation, across all the links in the supply chain. To better understand the manufacturing aspect of the clean energy economy, we have developed key metrics for systematically measuring and benchmarking international manufacturing of clean energy technologies. The metrics are: trade, market size, manufacturing value-added, and manufacturing capacity and production. These metrics were applied to twelve global economies and four representative technologies: wind turbine components, crystalline silicon solar photovoltaic modules, vehicle lithium ion battery cells, and light emitting diode packages for efficient lighting and other consumer products. The results indicated that clean energy technologies are being developed via complex, dynamic, and global supply chains, with individual economies benefiting from different technologies and links in the supply chain, through both domestic manufacturing and global trade.

  4. Marginal costs for intensified energy-efficiency measures

    Jakob, J.; Jochem, E.; Christen, K.

    2002-01-01

    The costs and benefits of investments in measures designed to improve the energy efficiency of residential buildings (in particular investments in heat insulation) were calculated as a function of increasing energy efficiency for new and renovated buildings and for single-family homes and apartment buildings. These investments in measures to improve efficiency mostly involve with the building envelope and ventilation systems and aim to successively reduce the space-heating needs of the buildings. The measures range from present-day building and renovation methods through to the 'Minergie' and 'Passive House' ('Minergie-P' in Switzerland) standards for low and very-low energy consumption buildings. Cost-benefit ratios were determined for individual building components, individual building concepts and for the whole of Switzerland, using both the average-cost as well as the pure marginal-cost methods (energy-economics level). The collection of empirical data (especially on costs) was an integral and important part of the project. The marginal costs were then compared with the benefits arising from the costs for space heating that were avoided, and, using a few typical cases as examples, with the so-called co-benefits, which are to be implemented in part by private persons and companies. For their quantification, methods were developed and used in case studies; in addition, avoided external costs are also considered. The marginal costs were also calculated for periods of time in the future, whereby they were made dynamic, according to their share of innovation, using the learning-curve method (learning and scaling effects). As far as the findings are concerned, there can be no doubt that the potential to be opened up for increasing energy efficiency using heat insulation measures is high, both for renovations and new construction work. A large portion of this potential is already economically viable and even more so when the possible risks of energy price increases

    The fuel cells transform the chemical energy stored in the connection H-H of the H{sub 2} molecule in electric energy and water vapor when is combines with the oxygen. Even when the hydrogen has a high potential as energy source, its handling is difficult (storage and transport). This has motivated the search of hydrogen production methods in situ starting from liquid fuels like the methanol or ethanol through the reaction of reforming. The methanol is a fuel of easy availability for fuel cells with electronic applications and of transport. Although the methanol energy density is approximately half of the gasoline and diesel, it is more reagent and can be used directly in fuel cells or can also be reformed to low temperatures for the hydrogen obtaining to be used in fuel cells of proton exchange. In this article the results obtained of the systems, Cu-Ni/ZrO{sub 2} and Ag-Au(1-D)-CeO{sub 2} are presented and can be competitive to generate H{sub 2} and being used in the fuel cells to generate energy.

    To propose measures for enhancing thermal energy utilization by analyzing drying process and operation principle of fluidized bed dryers,in order to guide optimization and upgrade of fluidized bed drying equipment. Through a systematic analysis on drying process and operation principle of fluidized beds,the energy conservation law was adopted to calculate thermal energy of dryers. The thermal energy of fluidized bed dryers is mainly used to make up for thermal consumption of water evaporation (Qw), hot air from outlet equipment (Qe), thermal consumption for heating and drying wet materials (Qm) and heat dissipation to surroundings through hot air pipelines and cyclone separators. Effective measures and major approaches to enhance thermal energy utilization of fluidized bed dryers were to reduce exhaust gas out by the loss of heat Qe, recycle dryer export air quantity of heat, preserve heat for dry towers, hot air pipes and cyclone separators, dehumidify clean air in inlets and reasonably control drying time and air temperature. Such technical parameters such air supply rate, air inlet temperature and humidity, material temperature and outlet temperature and humidity are set and controlled to effectively save energy during the drying process and reduce the production cost.

  8. Measuring the electron beam energy in a magnetic bunch compressor

    Hacker, Kirsten

    2010-09-01

    Within this thesis, work was carried out in and around the first bunch compressor chicane of the FLASH (Free-electron LASer in Hamburg) linear accelerator in which two distinct systems were developed for the measurement of an electron beams' position with sub-5 μm precision over a 10 cm range. One of these two systems utilized RF techniques to measure the difference between the arrival-times of two broadband electrical pulses generated by the passage of the electron beam adjacent to a pickup antenna. The other system measured the arrival-times of the pulses from the pickup with an optical technique dependent on the delivery of laser pulses which are synchronized to the RF reference of the machine. The relative advantages and disadvantages of these two techniques are explored and compared to other available approaches to measure the same beam property, including a time-of-flight measurement with two beam arrival-time monitors and a synchrotron light monitor with two photomultiplier tubes. The electron beam position measurement is required as part of a measurement of the electron beam energy and could be used in an intra-bunch-train beam-based feedback system that would stabilize the amplitude of the accelerating field. By stabilizing the accelerating field amplitude, the arrival-time of the electron beam can be made more stable. By stabilizing the electron beam arrival-time relative to a stable reference, diagnostic, seeding, and beam-manipulation lasers can be synchronized to the beam. (orig.)

  9. Multiloop atom interferometer measurements of chameleon dark energy in microgravity

    Chameleon field is one of the promising candidates of dark energy scalar fields. As in all viable candidate field theories, a screening mechanism is implemented to be consistent with all existing tests of general relativity. The screening effect in the chameleon theory manifests its influence limited only to the thin outer layer of a bulk object, thus producing extra forces orders of magnitude weaker than that of the gravitational force of the bulk. For pointlike particles such as atoms, the depth of screening is larger than the size of the particle, such that the screening mechanism is ineffective and the chameleon force is fully expressed on the atomic test particles. Extra force measurements using atom interferometry are thus much more sensitive than bulk mass based measurements, and indeed have placed the most stringent constraints on the parameters characterizing chameleon field. In this paper, we present a conceptual measurement approach for chameleon force detection using atom interferometry in microgravity, in which multiloop atom interferometers exploit specially designed periodic modulation of chameleon fields. We show that major systematics of the dark energy force measurements, i.e., effects of gravitational forces and their gradients, can be suppressed below all hypothetical chameleon signals in the parameter space of interest.

    To test the application of doubly labeled water under adverse field conditions, energy expenditures of 16 special operations soldiers were measured during a 28-day field training exercise. Subjects were matched by fat-free mass and divided equally between an ad libitum ready-to-eat meal diet and a 2,000 kcal/day lightweight ration. Subjects recorded intakes daily, and body composition was measured before and after the exercise. At the beginning of the study, subjects moved to a new northerly location and, therefore, a new water supply. To compensate for this, a group of soldiers who did not receive heavy water was followed to measure isotopic base-line changes. Energy expenditure by doubly labeled water was in agreement with intake/balance (3,400 ± 260 vs. 3,230 ± 520 kcal/day). The overall coefficient of variation of energy expenditure by doubly labeled water was half that of intake/balance (7.6 vs. 16.1%). The coefficient of variation of repeat measures with doubly labeled water was 7.3%. Energy expenditure of the ready-to-eat meal group, 3,540 ± 180 kcal/day, was not significantly different from the lightweight ration group, 3,330 ± 301 kcal/day. Doubly labeled water was valid under field conditions

    In England, housing accounts for some 30% of total fuel consumption and a similar proportion of energy-related carbon dioxide (CO/sub 2/) emission. A study has been conducted to analyse the effect of the legislations and UK thermal building regulations on national energy consumption in housing. This research paper presents data on the percentage of dwelling stock, the energy consumption, energy cost and carbon dioxide (CO/sub 2/) emission in different types of dwellings, which comply different building regulations from 1965 to 1995. It was found that. 66% of the dwelling stock, which comply the building Regulations before 1965, consumes 73% of total energy used in housing. This dwelling stock is also responsible for 75% of carbon dioxide (CO/sub 2/) emission. Whereas currently only 4% of the dwelling stock complies the latest building regulations 1995 which consume 2 % of energy and produce a similar percentage of carbon dioxide (CO/sub 2/) emission in housing. Since the large portion of the dwelling stock is comprised of old dwellings, therefore the greatest potential for energy conservation measures can be found in improving these dwellings instead of constructing new dwellings.

    1996-12-01

    Measurements with a combined cup anemometer/wind vane instrument, developed at the Department of Meteorology in Uppsala, is presented. The instrument has a frequency response of about 1 Hz, making it suitable not only for mean wind measurements, but also for studies of atmospheric turbulence. It is robust enough to be used for climatological purposes. Comparisons with data from a hot-film anemometer show good agreement, both as regards standard deviations and the spectral decomposition of the turbulent wind signal. The cup anemometer/wind vane instrument is currently used at three sites within the Swedish wind energy research programme. These measurements are shortly described, and a few examples of the results are given. 1 ref, 10 figs

    Linac4, a 160 MeV normal-conducting H- linear accelerator, is the first step in the upgrade of the beam intensity available from the LHC proton injectors at CERN. The Linac4 Low Energy Beam Transport (LEBT) line from the pulsed 2 MHz RF driven ion source, to the 352 MHz RFQ has been built and installed at a test stand, and has been used to transport and match to the RFQ a pulsed 14 mA H- beam at 45 keV. A temporary slit-and-grid emittance measurement system has been put in place to characterize the beam delivered to the RFQ. In this paper a description of the LEBT and its beam diagnostics is given, and the results of beam emittance measurements and beam transmission measurements through the RFQ are compared with the expectation from simulations.

  14. A gateless charge integrator for Borexino energy measurement

    1999-01-01

    A gateless charge integrator designed for the energy measurement in the Borexino experiment is described and the results of various tests performed on prototypes are shown. The circuit integrates always its input taking advantage of the AC coupling to the photomultipliers that equalizes to zero the charge associated with each event signal. A double sampling of the integrator output allows to perform a charge measurement in principle without dead time, avoiding the use of gate signals and baseline restoration networks and permitting a precise detection of the fast correlated events (delayed coincidences due to the decay of a nuclide producing a daughter having a lifetime in the tens of ns time range). The precision of the charge measurement is discussed together with the performances of the front end Borexino board where the integrator is mounted

    We report on laboratory studies of the effectiveness of directed energy planetary defense as a part of the DE-STAR (Directed Energy System for Targeting of Asteroids and exploRation) program. DE-STAR and DE-STARLITE are directed energy "stand-off" and "stand-on" programs, respectively. These systems consist of a modular array of kilowatt-class lasers powered by photovoltaics, and are capable of heating a spot on the surface of an asteroid to the point of vaporization. Mass ejection, as a plume of evaporated material, creates a reactionary thrust capable of diverting the asteroid's orbit. In a series of papers, we have developed a theoretical basis and described numerical simulations for determining the thrust produced by material evaporating from the surface of an asteroid. In the DESTAR concept, the asteroid itself is used as the deflection "propellant". This study presents results of experiments designed to measure the thrust created by evaporation from a laser directed energy spot. We constructed a vacuum chamber to simulate space conditions, and installed a torsion balance that holds a common space target sample. The sample is illuminated with a fiber array laser with flux levels up to 60 MW/m2 , which allows us to simulate a mission level flux but on a small scale. We use a separate laser as well as a position sensitive centroid detector to readout the angular motion of the torsion balance and can thus determine the thrust. We compare the measured thrust to the models. Our theoretical models indicate a coupling coefficient well in excess of 100 μN/Woptical, though we assume a more conservative value of 80 μN/Woptical and then degrade this with an optical "encircled energy" efficiency of 0.75 to 60 μN/Woptical in our deflection modeling. Our measurements discussed here yield about 45 μN/Wabsorbed as a reasonable lower limit to the thrust per optical watt absorbed. Results vary depending on the material tested and are limited to measurements of 1 axis, so

  17. Power's promise: electricity reforms in Eastern Europe and Central Asia, vol. 1

    Energy Technology Data Exchange (ETDEWEB)

    Lampietti, J. (ed.)

    2004-06-01

    This study analyzes the fiscal, efficiency, social, and environmental impact of power sector reforms in seven countries in the Europe and East Asia region - Armenia; Azerbaijan; Georgia; Hungary; Kazakhstan and POland. It finds sector deficits have been falling over the last decade and that the savings from lower sector deficits did not translate into higher social spending. More emphasis must be placed on monitoring deficits and tailoring policy reform to country specific circumstances. The impact of reform on utility efficiency, as measured by the cost of generation, system loss collections, and operational efficiency, is ambiguous. While overall revenue per kilowatt hour increased in almost all countries, problems continue with losses, collection rates, and staffing. In terms of social impacts, electricity spending as a share of income increased, especially for the poor, while consumption stayed the same. In terms of environmental impacts, reforms did slightly improve energy efficiency in power plants though this has little direct impact on human health because the electricity sector's share of the total health damage from air pollution is negligible. Several lessons emerge from the analysis. Undertaking simple ex ante simulations of reform impacts will allow better identification of potential reform benefits and costs. Placing more emphasis on outcome-based indicators of service quality would help ensure that future operations produce the intended end-user benefits. In many cases, tariff increases can and should be explicitly timed to coincide with service quality improvements. 24 figs., 15 tabs., 10 annexes.

    This paper presents data on measurement of actual solar radiation in Abu Dhabi (24.43 deg. N, 54.45 deg. E). Global solar radiation and surface temperatures were measured and analyzed for one complete year. High resolution, real-time solar radiation and other meteorological data were collected and processed. Daily and monthly average solar radiation values were calculated from the one-minute average recorded values. The highest daily and monthly mean solar radiation values were 369 and 290 W/m 2 , respectively. The highest one-minute average daily solar radiation was 1041 W/m 2 . Yearly average daily energy input was 18.48 MJ/m 2 /day. Besides the global solar radiation, the daily and monthly average clearness indexes along with temperature variations are discussed. When possible, global solar energy radiation and some meteorological data are compared with corresponding data in other Arab state capitals. The data collected indicate that Abu Dhabi has a strong potential for solar energy capture

    A novel, non-invasive method of measuring the beam energy at the International Linear Collider is proposed. Laser light collides head-on with beam particles and either the energy of the Compton scattered electrons near the kinematic end-point is measured or the positions of the Compton backscattered {gamma}-rays, the edge electrons and the unscattered beam particles are recorded. A compact layout for the Compton spectrometer is suggested. It consists of a bending magnet and position sensitive detectors operating in a large radiation environment. Several options for high spatial resolution detectors are discussed. Simulation studies support the use of an infrared or green laser and quartz fiber detectors to monitor the backscattered photons and edge electrons. Employing a cavity monitor, the beam particle position downstream of the magnet can be recorded with submicrometer precision. Such a scheme provides a feasible and promising method to access the incident beam energy with precisions of 10{sup -4} or better on a bunch-to-bunch basis while the electron and positron beams are in collision.

  1. Measurement of Exciton Binding Energy of Monolayer WS2

    Science.gov (United States)

    Chen, Xi; Zhu, Bairen; Cui, Xiaodong

    Excitonic effects are prominent in monolayer crystal of transition metal dichalcogenides (TMDCs) because of spatial confinement and reduced Coulomb screening. Here we use linear differential transmission spectroscopy and two-photon photoluminescence excitation spectroscopy (TP-PLE) to measure the exciton binding energy of monolayer WS2. Peaks for excitonic absorptions of the direct gap located at K valley of the Brillouin zone and transitions from multiple points near Γ point of the Brillouin zone, as well as trion side band are shown in the linear absorption spectra of WS2. But there is no gap between distinct excitons and the continuum of the interband transitions. Strong electron-phonon scattering, overlap of excitons around Γ point and the transfer of the oscillator strength from interband continuum to exciton states make it difficult to resolve the electronic interband transition edge even down to 10K. The gap between excited states of the band-edge exciton and the single-particle band is probed by TP-PLE measurements. And the energy difference between 1s exciton and the single-particle gap gives the exciton binding energy of monolayer WS2 to be about 0.71eV.

    The response function and detection efficiency of 2''φ x 2''L plastic (PilotU) and NE213 liquid (2''NE213) scintillators, which were used for the measurement of secondary neutrons from high energy electron induced reactions, were measured at Heavy Ion Medical Accelerator in Chiba (HIMAC). High energy neutrons were produced via 400 MeV/n C beam bombardment on a thick graphite target. The detectors were placed at 15 deg with respect to C beam axis, 5 m away from the target. As standard, a 5''φ x 5''L NE213 liquid scintillator (5''NE213) was also placed at same position. Neutron energy was determined by the time-of-flight method with the beam pickup scintillator in front of the target. In front of the detectors, veto scintillators were placed to remove charged particle events. All detector signals were corrected with list mode event by event. We deduce neutron spectrum for each detectors. The efficiency curves for pilotU and 2''NE213 were determined on the bases of 5 N E213 neutron spectrum and its efficiency calculated by CECIL code.

    2000-01-01

    As compared to electron storage rings, one advantage of recirculating linear accelerators is that the beam properties at target are no longer dominated by the equilibrium between quantum radiative diffusion and radiation damping because new beam is continually injected into the accelerator. This allows the energy spread from a CEBAF-type machine to be relatively small; the measured energy spread from CEBAF at 4 GeV is less than 100 parts per million accumulated over times of order several days. In this paper, the various subsystems contributing to the energy spread of a CEBAF-type accelerator are reviewed, as well as the machine diagnostics and controls that are used in CEBAF to ensure that a small energy spread is provided during routine running. Examples of relevant developments are (1) stable short bunches emerging from the injector, (2) precision timing and phasing of the linacs with respect to the centroid of the beam bunches on all passes, (3) implementing 2 kHz sampling rate feedback systems for final ...

    The evaporative fraction is a ratio that expresses the proportion of turbulent flux energy over land surfaces devoted to evaporation and transpiration (evapotranspiration). It has been used to characterize the energy partition over land surfaces and has potential for inferring daily energy balance information based on mid-day remote sensing measurements. The HAPEX-MOBILHY program`s SAMER system provided surface energy balance data over a range of agricultural crops and soil types. The databases from this large-scale field experiment was analyzed for the purpose of studying the behavior and daylight stability of the evaporative fraction in both ideal and general meteorological conditions. Strong linear relations were found to exist between the mid-day evaporative fraction and the daylight mean evaporative fraction. Statistical tests however rejected the hypothesis that the two quantities were equal. The relations between the evaporative fraction and the surface soil moisture as well as soil moisture in the complete vegetation root zone were also explored.

    2007-05-15

    The measurement of the specific energy loss due to ionisation, dE/dx, in a drift chamber is a very important tool for particle identification in final states of reactions between high energetic particles. Such identification requires a well understood dE/dx measurement including a precise knowledge of its uncertainties. Exploiting for the first time the full set of ZEUS data from the HERA operation between 1996 and 2005 twelve detector-related influences affecting the dE/dx measurement of the ZEUS Central Tracking Detector have been identified, separately studied and parameterised. A sophisticated iterative procedure has been developed to correct for these twelve effects, which takes into account the correlations between them. A universal parameterisation of the detector-specific Bethe-Bloch curve valid for all particle species has been extracted. In addition, the various contributions to the measurement uncertainty have been disentangled and determined. This yields the best achievable prediction for the single-track dE/dx resolution. For both the analysis of the measured data and the simulation of detector performance, the detailed understanding of the measurement and resolution of dE/dx gained in this work provides a tool with optimum power for particle identification in a physics studies.

    We present measurements of the recoil proton polarization for the d(polarized y, polarized p)n reaction at thetac.m. = 90 degrees for photon energies up to 2.4 GeV. These are the first data in this reaction for polarization transfer with circularly polarized photons. The induced polarization py vanishes above 1 GeV, contrary to meson-baryon model expectations, in which resonances lead to large polarizations. However, the polarization transfer Cx does not vanish above 1 GeV, inconsistent with hadron helicity conservation. Thus, we show that the scaling behavior observed in the d(y,p)n cross sections is not a result of perturbative QCD. These data should provide important tests of new nonperturbative calculations in the intermediate energy regime

    Coastal mangroves lose large amounts of water through evapotranspiration (ET) that can be equivalent to the amount of annual rainfall in certain years. Satellite remote sensing has been used to estimate surface energy and ET variability in many forested ecosystems, yet has been widely overlooked in mangrove forests. Using a combination of long-term datasets (30-year) acquired from the NASA Landsat 5 and 7 satellite databases, the present study investigated ET and surface energy balance variability between two mangrove forest sites in the Caribbean: 1) Everglades National Park (ENP; Florida, USA) and 2) Sian Ka'an Biosphere Reserve (SKBR; Quintana Roo, Mexico). A satellite-derived surface energy balance model was used to estimate ET in tall and scrub mangroves environments at ENP and SKBR. Results identified significant differences in soil heat flux measurements and ET between the tall and scrub mangrove environments. Scrub mangroves exhibited the highest soil heat flux coincident with the lowest biophysical indices (i.e., Fractional Vegetation Cover, Normalized Difference Vegetation Index, and Soil-Adjusted Vegetation Index) and ET rates. Mangrove damage and mortality was observed on the satellite images following strong tropical storms and associated with anthropogenic modifications and resulted in low values in spectral vegetation indices, higher soil heat flux, and higher ET. Recovery of the spectral characteristics, soil heat flux and ET was within 1-2 years following hurricane disturbance while, degradation caused by human disturbance persisted for many years. Remotely sensed ET of mangrove forests can provide estimates over a few decades and provide us with some understanding of how these environments respond to disturbances to the landscape in periods where no ground data exists or in locations that are difficult to access. Moreover, relationships between energy and water balance components developed for the coastal mangroves of Florida and Mexico could be

  14. Predissociation measurements of bond dissociation energies: VC, VN, and VS

    2016-06-21

    The abrupt onset of predissociation in the congested electronic spectra of jet-cooled VC, VN, and VS has been observed using resonant two-photon ionization spectroscopy. It is argued that because of the high density of electronic states in these molecules, the predissociation threshold occurs at the thermochemical threshold for the production of separated atoms in their ground electronic states. As a result, the measured threshold represents the bond dissociation energy. Using this method, bond dissociation energies of D{sub 0}(V C) = 4.1086(25) eV, D{sub 0}(V N) = 4.9968(20) eV, and D{sub 0}(V S) = 4.5353(25) eV are obtained. From these values, enthalpies of formation are derived as Δ{sub f,0K}H°(V C(g)) = 827.0 ± 8 kJ mol{sup −1}, Δ{sub f,0K}H°(V N(g)) = 500.9 ± 8 kJ mol{sup −1}, and Δ{sub f,0K}H°(V S(g)) = 349.3 ± 8 kJ mol{sup −1}. Using a thermochemical cycle and the well-known ionization energies of V, VC, and VN, our results also provide D{sub 0}(V{sup +}–C) = 3.7242(25) eV and D{sub 0}(V{sup +}–N) = 4.6871(20) eV. These values are compared to previous measurements and to computational results. The precision of these bond dissociation energies makes them good candidates for testing computational chemistry methods, particularly those that employ density functional theory.

  15. Potential environmental effects of energy conservation measures in northwest industries

    1992-01-01

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

    2006-12-01

    This study was commissioned by the Dutch Ministry of Economic Affairs in order to address the will of the parliament to investigate policies and measures in order to improve energy efficiency. The analysis is targeted at increasing the annual energy efficiency improvement in the Netherlands from 1% to 2%. It shows that the following policies and measures are necessary to achieve 2%. Regulation has been defined for improving energy efficiency in dwellings and commercial buildings, to be implemented when ownership changes. EU regulation is required for appliances, office equipment and cars, delivery vans and efficient tires. Financial incentives are added for the purchase of efficient cars, the reduction of mileage and for intra-European air transport. Taxation is suggested for industry, the energy sector and horticulture, where less efficient plants have to pay and efficient ones benefit. Total costs for the Dutch economy amount to 3.5 billion euros annually. Implementing the proposed policy packages will require a considerable effort of governments, citizens and companies to overcome societal barriers. In many cases, introduction of the necessary policies and measures depends on European legislation [nl

  17. Experimental analysis of an autothermal reformer for automotive purposes

    International Nuclear Information System (INIS)

    2004-01-01

    This paper describes the experimental analysis, concomitant with modeling research, to determine improved operating parameters and design of an autothermal reformer. The reformer, utilizing both partial oxidation and steam reforming reactions, along with the water gas shift phenomena is well suited for the mobile application of transportation. This is due to the novel geometry of the autothermal reformer, which seeks to improve the heat transfer characteristics of the process, whereby the exothermic partial oxidation reaction provides the heat energy required to drive the steam reforming reaction, to the point of a thermally neutral system. The paper will present data from the experimental results of reforming iso-octane as a surrogate for gasoline in the form of reformate composition, iso-octane conversion percentages and efficiencies in terms of hydrogen realized per mol of fuel input.

    Using the Low Energy Neutral Atom Spectrometer, measurements were made of the H 0 and D 0 efflux from PLT during ion cyclotron heating experiments. The application of rf power at frequencies appropriate to fundamental and 2nd-harmonic heating results in a rapid, toroidally uniform rise in the charge-exchange efflux at a rate of about 10 15 cm -2 s -1 MW -1 . This flux increase is larger at lower plasma currents. The cause of this flux and its impact on plasma behavior are discussed

    1984-01-01

    In relativistic nuclear collisions the multiplicity of charged particles reflects the violence of the reaction and, presumably, the impact parameter. Furthermore, the total transverse energy in a collision might be a signature of compression. Both quantities are global features that can be measured in the Plastic Ball. The total mass in an event in light charge fragments can be detected (with assumptions made in certain kinematic regions) through particle identification. In addition, the neutron detection efficiency is quite high because of the large thickness of the plastic scintillator in the Plastic Ball. Here the authors present several global quantities for the reaction of 400 MeV/nucleon Nb + Nb

    An increase in energy transfer efficiency of the capacitor bank to the plasma was obtained when the electrical system of a theta-pinch was changed so that the ratio of total inductance to coil inductance was switched of 1/6 to 1/2. A further increase about 20% was obtained for 16/1 ratio. The measurements were made through the current discharge decay, and the spectral analysis of the emitted light from theta-pinch shows a correspondent efficiency increase. (author)

  1. Measuring the electron beam energy in a magnetic bunch compressor

    Energy Technology Data Exchange (ETDEWEB)

    Hacker, Kirsten

    2010-09-15

    Within this thesis, work was carried out in and around the first bunch compressor chicane of the FLASH (Free-electron LASer in Hamburg) linear accelerator in which two distinct systems were developed for the measurement of an electron beams' position with sub-5 {mu}m precision over a 10 cm range. One of these two systems utilized RF techniques to measure the difference between the arrival-times of two broadband electrical pulses generated by the passage of the electron beam adjacent to a pickup antenna. The other system measured the arrival-times of the pulses from the pickup with an optical technique dependent on the delivery of laser pulses which are synchronized to the RF reference of the machine. The relative advantages and disadvantages of these two techniques are explored and compared to other available approaches to measure the same beam property, including a time-of-flight measurement with two beam arrival-time monitors and a synchrotron light monitor with two photomultiplier tubes. The electron beam position measurement is required as part of a measurement of the electron beam energy and could be used in an intra-bunch-train beam-based feedback system that would stabilize the amplitude of the accelerating field. By stabilizing the accelerating field amplitude, the arrival-time of the electron beam can be made more stable. By stabilizing the electron beam arrival-time relative to a stable reference, diagnostic, seeding, and beam-manipulation lasers can be synchronized to the beam. (orig.)

  2. Using Energy Peaks to Measure New Particle Masses

    CERN Document Server

    Agashe, Kaustubh; Kim, Doojin

    2014-01-01

    We discussed in arXiv:1209.0772 that the laboratory frame distribution of the energy of a massless particle from a two-body decay at a hadron collider has a peak whose location is identical to the value of this daughter's (fixed) energy in the rest frame of the corresponding mother particle. For that result to hold we assumed that the mother is unpolarized and has a generic boost distribution in the laboratory frame. In this work we discuss how this observation can be applied for determination of masses of new particles, without requiring a full reconstruction of their decay chains or information about the rest of the event. We focus on a two-step cascade decay of a massive particle that has one invisible particle in the final state: C -> Bb -> Aab, where C, B and A are new particles of which A is invisible and a, b are visible particles. Combining the measurements of the peaks of energy distributions of a and b with that of the edge in their invariant mass distribution, we demonstrate that it is in principle...

  3. Energy Approach to Measure the Region’s Assimilative Capacity

    Full Text Available One of the important problems of the environmental economics is the development of methodology for quantifying the assimilative capacity (AC of a territory. The article analyzes the existing approaches to determining and assessing the AC of a territory. We justify the advantages of using the energy approach. The authors’ method consists in using the maximum permissible energy load (MPEL for quantitative assessment of the AC of a territory. MPEL is a value that the ecological and economic system can withstand for a long time without changing its properties. We determine MPEL on the basis of data on the ability of various categories of land to absorb greenhouse gases (GHG, as well as the specific GHG emissions per ton of conventional fuel. Further, we compare the calculated value of MPEL in fuel equivalents with the actual consumption of fuel resources for the needs of the national economy. These values ratio can serve as a standard for measuring and balancing the environmental and economic system. The authors have validated the described method on the example of the Sverdlovsk region, which is characterized by a high level of man’s impact. Calculations show that the actual consumption of fossil fuels in the region exceeds MPEL. That indicates an imbalance in the ecological and economic system and may lead to further deterioration of the environmental quality in the region. The proposed methodological approach and calculations can be used when developing strategic planning documents for a territory, including its energy strategy

  4. Calculation and Measurement of Low-Energy Radiative Moller Scattering

    2017-09-01

    A number of current nuclear physics experiments have come to rely on precise knowledge of electron-electron (Moller) and positron-electron (Bhabha) scattering. Some of these experiments, having lepton beams on targets containing atomic electrons, use these purely-QED processes as normalization. In other scenarios, with electron beams at low energy and very high intensity, Moller scattering and radiative Moller scattering have such enormous cross-sections that the backgrounds they produce must be understood. In this low-energy regime, the electron mass is also not negligible in the calculation of the cross section. This is important, for example, in the DarkLight experiment (100 MeV). As a result, we have developed a new event generator for the radiative Moller and Bhabha processes, with new calculations that keep all terms of the electron mass. The MIT High Voltage Research Laboratory provides us a unique opportunity to study this process experimentally and compare it with our work, at a low beam energy of 2.5 MeV where the effects of the electron mass are significant. We are preparing a dedicated apparatus consisting of a magnetic spectrometer in order to directly measure this process. An overview of the calculation and the status of the experiment will be presented.

    2012-01-01

    Full Text Available Introduction. Aim of this study was to compare the resting energy expenditure (REE measured by the Douglas bag method with the REE estimated with the FitMate method, the Harris-Benedict equation, and the Müller et al. equation for individuals with BMI < 18.5 kg/m2 in a severe group of underweight patients with anorexia nervosa (AN. Methods. 15 subjects with AN participated in the study. The Douglas bag method and the FitMate method were used to measure REE and the dual energy X-ray absorptiometry to assess body composition after one day of refeeding. Results. FitMate method and the Müller et al. equation gave an accurate REE estimation, while the Harris-Benedict equation overestimated the REE when compared with the Douglas bag method. Conclusion. The data support the use of the FitMate method and the Müller et al. equation, but not the Harris-Benedict equation, to estimate REE in AN patients after short-term refeeding.

    This study proposes to determine the correlation between the Volume Pulse Height (VPH) measured by nuclear emulsion and Linear Energy Transfer (LET) calculated by Monte Carlo simulation based on Geant4. The nuclear emulsion was irradiated at the National Cancer Center (NCC) with a therapeutic proton beam and was installed at 5.2 m distance from the beam nozzle structure with various thicknesses of water-equivalent material (PMMA) blocks to position with specific positions along the Bragg curve. After the beam exposure and development of the emulsion films, the films were scanned by S-UTS developed in Nagoya University. The proton tracks in the scanned films were reconstructed using the ‘NETSCAN’ method. Through this procedure, the VPH can be derived from each reconstructed proton track at each position along the Bragg curve. The VPH value indicates the magnitude of energy loss in proton track. By comparison with the simulation results obtained using Geant4, we found the correlation between the LET calculated by Monte Carlo simulation and the VPH measured by the nuclear emulsion.

    2017-08-01

    The Global Energy Balance Archive (GEBA) is a database for the central storage of the worldwide measured energy fluxes at the Earth's surface, maintained at ETH Zurich (Switzerland). This paper documents the status of the GEBA version 2017 dataset, presents the new web interface and user access, and reviews the scientific impact that GEBA data had in various applications. GEBA has continuously been expanded and updated and contains in its 2017 version around 500 000 monthly mean entries of various surface energy balance components measured at 2500 locations. The database contains observations from 15 surface energy flux components, with the most widely measured quantity available in GEBA being the shortwave radiation incident at the Earth's surface (global radiation). Many of the historic records extend over several decades. GEBA contains monthly data from a variety of sources, namely from the World Radiation Data Centre (WRDC) in St. Petersburg, from national weather services, from different research networks (BSRN, ARM, SURFRAD), from peer-reviewed publications, project and data reports, and from personal communications. Quality checks are applied to test for gross errors in the dataset. GEBA has played a key role in various research applications, such as in the quantification of the global energy balance, in the discussion of the anomalous atmospheric shortwave absorption, and in the detection of multi-decadal variations in global radiation, known as global dimming and brightening. GEBA is further extensively used for the evaluation of climate models and satellite-derived surface flux products. On a more applied level, GEBA provides the basis for engineering applications in the context of solar power generation, water management, agricultural production and tourism. GEBA is publicly accessible through the internet via http://www.geba.ethz.ch. Supplementary data are available at https://doi.org/10.1594/PANGAEA.873078.

  14. Cosmic shear measurements with Dark Energy Survey Science Verification data

    International Nuclear Information System (INIS)

    Becker, M. R.

    2016-01-01

    Here, we present measurements of weak gravitational lensing cosmic shear two-point statistics using Dark Energy Survey Science Verification data. We demonstrate that our results are robust to the choice of shear measurement pipeline, either ngmix or im3shape, and robust to the choice of two-point statistic, including both real and Fourier-space statistics. Our results pass a suite of null tests including tests for B-mode contamination and direct tests for any dependence of the two-point functions on a set of 16 observing conditions and galaxy properties, such as seeing, airmass, galaxy color, galaxy magnitude, etc. We use a large suite of simulations to compute the covariance matrix of the cosmic shear measurements and assign statistical significance to our null tests. We find that our covariance matrix is consistent with the halo model prediction, indicating that it has the appropriate level of halo sample variance. We also compare the same jackknife procedure applied to the data and the simulations in order to search for additional sources of noise not captured by the simulations. We find no statistically significant extra sources of noise in the data. The overall detection significance with tomography for our highest source density catalog is 9.7σ. Cosmological constraints from the measurements in this work are presented in a companion paper

  15. Pore size determination from charged particle energy loss measurement

    International Nuclear Information System (INIS)

    Brady, F.P.; Armitage, B.H.

    1977-01-01

    A new method aimed at measuring porosity and mean pore size in materials has been developed at Harwell. The energy width or variance of a transmitted or backscattered charged particle beam is measured and related to the mean pore size via the assumption that the variance in total path length in the porous material is given by (Δx 2 )=na 2 , where n is the mean number of pores and a the mean pore size. It is shown on the basis of a general and rigorous theory of total path length distribution that this approximation can give rise to large errors in the mean pore size determination particularly in the case of large porosities (epsilon>0.5). In practice it is found that it is not easy to utilize fully the general theory because accurate measurements of the first four moments are required to determine the means and variances of the pore and inter-pore length distributions. Several models for these distributions are proposed. When these are incorporated in the general theory the determinations of mean pore size from experimental measurements on powder samples are in good agreement with values determined by other methods.

    The Global Energy Balance Archive (GEBA) is a database for the worldwide measured energy fluxes at the Earth's surface. GEBA is maintained at ETH Zurich (Switzerland) and has been founded in the 1980s by Prof. Atsumu Ohmura. It has continuously been updated and currently contains around 2500 stations with 500`000 monthly mean entries of various surface energy balance components. Many of the records extend over several decades. The most widely measured quantity available in GEBA is the solar radiation incident at the Earth's surface ("global radiation"). The data sources include, in addition to the World Radiation Data Centre (WRDC) in St. Petersburg, data reports from National Weather Services, data from different research networks (BSRN, ARM, SURFRAD), data published in peer-reviewed publications and data obtained through personal communications. Different quality checks are applied to check for gross errors in the dataset. GEBA is used in various research applications, such as for the quantification of the global energy balance and its spatiotemporal variation, or for the estimation of long-term trends in the surface fluxes, which enabled the detection of multi-decadal variations in surface solar radiation, known as "global dimming" and "brightening". GEBA is further extensively used for the evaluation of climate models and satellite-derived surface flux products. On a more applied level, GEBA provides the basis for engineering applications in the context of solar power generation, water management, agricultural production and tourism. GEBA is publicly accessible over the internet via www.geba.ethz.ch.

  20. The impact of education on the probability of receiving periodontal treatment. Causal effects measured by using the introduction of a school reform in Norway.

    Grytten, Jostein; Skau, Irene

    2017-09-01

    The aim of the present study was to estimate the causal effect of education on the probability of receiving periodontal treatment in the adult Norwegian population. In Norway, a substantial part of the cost of periodontal treatment is subsidized by the National Insurance Scheme. In that case, one might expect that the influence of individual resources, such as education, on receiving treatment would be reduced or eliminated. Causal effects were estimated by using data on a school reform in Norway. During the period 1960-1972, all municipalities in Norway were required to increase the number of compulsory years of schooling from seven to nine years. The education reform was used to create exogenous variation in the education variable. The education data were combined with large sets of data from the Norwegian Health Economics Administration and Statistics Norway. Since municipalities implemented the reform at different times, we have both cross-sectional and time-series variation in the reform instrument. Thus we were able to estimate the effect of education on the probability of receiving periodontal treatment by controlling for municipality fixed effects and trend variables. The probability of receiving periodontal treatment increased by 1.4-1.8 percentage points per additional year of schooling. This is a reasonably strong effect, which indicates that policies to increase the level of education in the population can be an effective tool to improve oral health, including periodontal health.

    During the last decade of the 20th Century, diverse campaigns for measuring the atmospheric energy balance were performed in downtown Mexico City (School of Mines and Preparatory School No. 7), in the southern suburbs (University Reserve) and in the surrounding rural areas (Plan Texcoco), in addition to a campaign carried out in 1985 in the Tacubaya district, a suburban western peripheral site. The objective was to obtain data for a better understanding of the climatic alterations due to urbanization, particularly to describe the role that the modification of the natural ground cover has played as a result of paving and the construction of urban canyons. In this paper, a review of these campaigns is presented. Energy partitioning in some areas (Tacubaya and Preparatory School No.7) is similar to that observed in urban centers of middle latitudes, whereas the major contrast was observed between Texcoco, with maximum energy consumption through evaporation, and School of Mines, where the latent heat is as low as in a desert. From the values of the correlations among the different components of energy balance, it may be possible to attempt the modeling of the diverse components of energy balance by means of regression equations starting from the net radiation. Those same coefficients distinguish the type of environment: urban, suburban or rural. [Spanish] Las primeras mediciones de balance energetico en la Ciudad de Mexico se realizaron en 1985 en un suburbio al poniente de la ciudad (el observatorio de Tacubaya). Ya en la decada de los anos noventa del siglo XX, dichas observaciones se multiplicaron tanto en el centro historico (antigua Escuela de Minas y en el edificio de la Preparatoria No. 7), como en otros sitios al sur (en terrenos de Ciudad Universitaria) y en la periferia rural (Plan Texcoco). El proposito de estas mediciones ha sido tener un mejor entendimiento de las alteraciones climaticas debidas a la urbanizacion. En este trabajo se presenta una revision

  2. Exploring the range of energy savings likely from energy efficiency retrofit measures in Ireland's residential sector

    Dineen, D.; Ó Gallachóir, B.P.

    2017-01-01

    This paper estimates the potential energy savings in the Irish residential sector by 2020 due to the introduction of an ambitious retrofit programme. We estimate the technical energy savings potential of retrofit measures targeting energy efficiency of the space and water heating end uses of the 2011 stock of residential dwellings between 2012 and 2020. We build eight separate scenarios, varying the number of dwellings retrofitted and the depth of retrofit carried out in order to investigate the range of energy savings possible. In 2020 the estimated technical savings potential lies in the range from 1713 GWh to 10,817 GWh, but is more likely to fall within the lower end of this range, i.e. between 1700 and 4360 GWh. When rebound effects are taken into account this reduces further to 1100 GWh and 2800 GWh per annum. The purpose of this paper was to test the robustness of the NEEAP target savings for residential retrofit, i.e. 3000 GWh by 2020. We conclude that this target is technically feasible but very challenging and unlikely to be achieved based on progress to date. It will require a significant shift towards deeper retrofit measures compared to what has been achieved by previous schemes. - Highlights: • Paper estimates range of energy savings likely from Irish residential retrofit. • Achieving NEEAP target savings of 3000 GWh by 2020 is feasible but very challenging. • Likely savings of 1100–2800 GWh per annum in 2020, including rebound. • NEEAP target unlikely to be achieved based on current trends.

    Thermal plasma technology can be efficiently used in the production of hydrogen and hydrogen-rich gases from methane and a variety of fuels. This paper describes progress in plasma reforming experiments and calculations of high temperature conversion of methane using heterogeneous processes. The thermal plasma is a highly energetic state of matter that is characterized by extremely high temperatures (several thousand degrees Celsius) and high degree of dissociation and substantial degree of ionization. The high temperatures accelerate the reactions involved in the reforming process. Hydrogen-rich gas (50% H{sub 2}, 17% CO and 33% N{sub 2}, for partial oxidation/water shifting) can be efficiently made in compact plasma reformers. Experiments have been carried out in a small device (2--3 kW) and without the use of efficient heat regeneration. For partial oxidation/water shifting, it was determined that the specific energy consumption in the plasma reforming processes is 16 MJ/kg H{sub 2} with high conversion efficiencies. Larger plasmatrons, better reactor thermal insulation, efficient heat regeneration and improved plasma catalysis could also play a major role in specific energy consumption reduction and increasing the methane conversion. A system has been demonstrated for hydrogen production with low CO content ({approximately} 1.5%) with power densities of {approximately} 30 kW (H{sub 2} HHV)/liter of reactor, or {approximately} 10 m{sup 3}/hr H{sub 2} per liter of reactor. Power density should further increase with increased power and improved design.

    Two recoil-distance-doppler-shift (RDDS) experiments were performed at the NSCL/MSU using Coulomb excitations of the projectile nuclei {sup 110}Pd, {sup 114}Pd at beam energies of 54 MeV/u in order to investigate the evolution of deformation of neutron rich paladium isotopes. The experimental set-up consisted of a dedicated plunger device, developed at the University of Cologne, the SEGA Ge-array and the S800 spectrometer. Lifetimes of the 2{sub 1}{sup +}-states in {sup 110}Pd and {sup 114}Pd were derived from the analysis of the {gamma}-line-shapes as well as from the measured decay-curves. Special features of the data analysis, e.g. features originating from the very high recoil velocities, are discussed.

    The Aerial Measuring Systems (AMS) is an aerial surveillance system. This system consists of remote sensing equipment to include radiation detectors; multispectral, thermal, radar, and laser scanners; precision cameras; and electronic imaging and still video systems. This equipment, in varying combinations, is mounted in an airplane or helicopter and flown at different heights in specific patterns to gather various types of data. This system is a key element in the US Department of Energy's (DOE) national emergency response assets. The mission of the AMS program is twofold--first, to respond to emergencies involving radioactive materials by conducting aerial surveys to rapidly track and map the contamination that may exist over a large ground area and second, to conduct routinely scheduled, aerial surveys for environmental monitoring and compliance purposes through the use of credible science and technology. The AMS program evolved from an early program, begun by a predecessor to the DOE--the Atomic Energy Commission--to map the radiation that may have existed within and around the terrestrial environments of DOE facilities, which produced, used, or stored radioactive materials.

    Lines of singly ionized Scandium (Sc II) along with other Iron group elements have been observed [1] in the region surrounding the massive star Eta Carinae [2,3] called the strontium filament (SrF). The last extensive analysis of Sc II was the four-decade old work of Johansson & Litzen [4], using low-resolution grating spectroscopy. To update and extend the Sc II spectra, we have made observation of Sc/Ar, Sc/Ne and Sc/Ge/Ar hollow cathode emission spectrum on the NIST high resolution FT700 UV/Vis and 2 m UV/Vis/IR Fourier transform spectrometers (FTS). More than 850 Sc II lines have been measured in the wavelength range of 187 nm to 3.2 μm. connecting a total of 152 energy levels. The present work also focuses to resolve hyperfine structure (HFS) in Sc II lines. We aim to obtain accurate transition wavelengths, improved energy levels and HFS constants of Sc II. The latest results from work in progress will be presented.Reference[1] Hartman H, Gull T, Johansson S and Smith N 2004 Astron. Astrophys. 419 215[2] Smith N, Morse J A and Gull T R 2004 Astrophys.

    The S143 experiment, at CERN in 1976, needed both the measurement and the identification of light nuclei, and especially the separation between 3 H and 3 He, over a large energy range. In the chosen solution, in addition to semiconductor detectors, some scintillation counters are used. The non-linearity of light versus energy of charged particles was complicated by the fact there was two different linear laws according to the charge of particles. To obtain good analogic signals over a dynamic range nearly equal to 200, the signals from several dynodes were used simultaneously. In the experimental setting up, each scintillator was put directly in contact with the corresponding photocathode. In spite of a special shielding, some perturbations due to the magnet placed close by required to bring important corrections to linear laws. Thanks to complementary informations from semiconductor counters, a full separation between charge 1 and charge 2 particles was possible. A suitable identification as guaranted among charge 1 particles, but only kinematic constraints gave the possibility to extract 4 He corresponding to the elastic scattering [fr

    Measurements of low-energy internal conversion electrons have been performed with high energy resolution in some N = 105 odd and odd-odd nuclei using a semi-circular spectrograph associated to a specific tape transport system. These experiments aimed to answer the following questions~: \\begin{itemize} \\item Do M3 isomeric transitions exist in $^{183}$Pt and $^{181}$Os, isotones of $^{184}$Au~? \\item Are the neutron configurations proposed to describe the isomeric and ground states of $^{184}$Au right or wrong~? \\item Does it exist an isomeric state in $^{182}$Ir, isotone of $^{181}$Os, $^{183}$Pt and $^{184}$Au~? \\item What are the spin and parity values of the excited states of $^{182}$Ir~? \\end{itemize} In $^{183}$Pt, the 35.0 keV M3 isomeric transition has been clearly observed and the reduced transition probability has been determined. The deduced hindrance factor is close to that observed in the neighbouring odd-odd $^{184}$Au nucleus. This confirms the neutron configurations previously proposed for the ...

    Contemporary science has brought about technological advances and an unprecedented understanding of the natural world. However, there are signs of dysfunction in the scientific community as well as threats from diverse antiscience and political forces. Incentives in the current system place scientists under tremendous stress, discourage cooperation, encourage poor scientific practices, and deter new talent from entering the field. It is time for a discussion of how the scientific enterprise can be reformed to become more effective and robust. Serious reform will require more consistent methodological rigor and a transformation of the current hypercompetitive scientific culture.

    Power systems based on fuel cells have been considered for residential and commercial applications in energy Distributed Generation (DG) market as these systems can minimize their acquisition, installation and operation high costs. In this work we present an experimental analysis of a power generation system formed by a 5 kW proton exchange membrane fuel cell unit and a natural gas reformer (fuel processor) for hydrogen production, of the CEPEL's Fuel Cell Laboratory. It was determined the electrical performance of the cogeneration system in function of the design and operational power plant parameters. Additionally, it was verified the influence of the activation conditions of the fuel cell electrocatalytic system on the system performance. It also appeared that the use of hydrogen produced from the natural gas catalytic reforming provided the system operation in excellent electrothermal stability conditions resulting in increase of the energy conversion efficiency and of the economicity of the cogeneration power plant. The maximum electrical efficiency achieved was around 38% and in all power range unit operated with average potential per single fuel cell higher than 0.60 V. (author)

    2018-03-01

    In this paper we report the activation of the dry reforming reaction by induction heating of a NiCo alloy. The catalyst plays a double role, serving both as a promoter for the reforming reaction and producing the heat induced by dissipation of the electromagnetic energy. The elevated temperatures imposed by the reforming reaction suggest the choice of an alloy with a Curie temperature >800°C. In this respect Ni:Co ratio 60:40 was chosen. Alloy active sites for CH4and CO2activation are created by a mechanochemical treatment of the alloy that increases solid-state defects. The catalyst has been successfully tested in a continuous-flow reactor working under atmospheric pressure. Methane conversion and hydrogen production yields have been measured as a function of the applied magnetic field, reactant flow rate and time on stream.

    1989-01-01

    This Decree abolishes the Brazilian National Institute of Colonization and Agrarian Reform (INCRA) and creates a Legal Institute of Rural Land (INTER) linked to the Ministry of Agrarian Reform (MIRAD) to perform the activities of INCRA. MIRAD will henceforth be responsible for the rights, powers, and obligations of INCRA and will supervise INCRA's property and resources. In this capacity MIRAD will supervise, coordinate, and execute activities related to agrarian reform and agricultural policy. Among these activities are the promotion of social justice and productivity through 1) the just and adequate distribution of ownership of rural land, 2) limitation of the acquisition of rural property by foreigners, and 3) encouragement of the harmonious development of rural life. In developing such activities MIRAD is to make use of legal measures contained in land law, including those relating to the selection of public rural lands, the privatization of rural land through regularization of ownership, colonization, zoning, and taxation. It is also authorized to expropriate and distribute unexploited or improperly exploited land to worker families, with priority going to labor cooperatives. Further provisions establish rules on expropriation. Among these is the requirement that forests must be protected.

  1. Measuring pion beta decay with high-energy pion beams

    McFarlane, W.K.; Hoffman, C.M.

    1993-01-01

    Improved measurements of the pion beta decay rate are possible with an intense high-energy pion beam. The rate for the decay π + → π 0 e + vε is predicted by the Standard Model (SM) to be R(π + → π 0 e + vε) = 0.3999±0.0005 s -1 . The best experimental number, obtained using in-flight decays, is R(π + → π 0 e + vε) = 0.394 ± 0.015 s -1 . A precise measurement would test the SM by testing the unitarity of the Cabibbo-Kobayashi-Maskawa matrix for which one analysis of the nuclear beta decay data has shown a 0.4% discrepancy. Several nuclear correction factors, needed for nuclear decay, are not present for pion beta decay, so that an experiment at the 0.2% level would be a significant one. Detailed study of possible designs will be needed, as well as extensive testing of components. The reduction of systematic errors to the 0.1% level can only be done over a period of years with a highly stable apparatus and beam. At a minimum, three years of occupancy of a beam line, with 800 hours per year, would be required

  2. Improvements of reforming performance of a nuclear heated steam reforming process

    1996-10-01

    Performance of an energy production process by utilizing high temperature nuclear process heat was not competitive to that by utilizing non-nuclear process heat, especially fossil-fired process heat due to its less favorable chemical reaction conditions. Less favorable conditions are because a temperature of the nuclear generated heat is around 950degC and the heat transferring fluid is the helium gas pressurized at around 4 MPa. Improvements of reforming performance of nuclear heated steam reforming process were proposed in the present report. The steam reforming process, one of hydrogen production processes, has the possibility to be industrialized as a nuclear heated process as early as expected, and technical solutions to resolve issues for coupling an HTGR with the steam reforming system are applicable to other nuclear-heated hydrogen production systems. The improvements are as follows: As for the steam reformer, (1) increase in heat input to process gas by applying a bayonet type of reformer tubes and so on, (2) increase in reforming temperature by enhancing heat transfer rate by the use of combined promoters of orifice baffles, cylindrical thermal radiation pipes and other proposal, and (3) increase in conversion rate of methane to hydrogen by optimizing chemical compositions of feed process gas. Regarding system arrangement, a steam generator and superheater are set in the helium loop as downstream coolers of the steam reformer, so as to effectively utilize the residual nuclear heat for generating feed steam. The improvements are estimated to achieve the hydrogen production rate of approximately 3800 STP-m 3 /h for the heat source of 10 MW and therefore will provide the potential competitiveness to a fossil-fired steam reforming process. Those improvements also provide the compactness of reformer tubes, giving the applicability of seamless tubes. (J.P.N.)

    The National Health System (ESY) in Greece, which was established in 1983, is in a state of continuous crisis. This situation is caused mainly by the system's problematic administration, low productivity and inadequate Primary Health Care. These have led the re-elected PASOK government to introduce by the end of 2000 a radical reform of the health system. The 200 reform measures announced by the new Minister of Health and Welfare include changes aiming at: the decentralization of the ESY, the creation of a unified financing system for the social insurance funds, a new management structure in public hospitals, the organization of a Primary Health System in urban areas, and the strengthening of Public Health and Health Promotion. These changes are presented and discussed in this paper.

    It is easy to measure energy consumption with a power meter. However, energy savings cannot be directly computed by the powers measured using existing power meter technologies, since the power consumption only reflects parts of the real energy flows. The International Performance Measurement and Verification Protocol (IPMVP) was proposed by the Efficiency Valuation Organization (EVO) to quantify energy savings using four different methodologies of A, B, C and D. Although energy savings can be...

    The Russian Government is pursuing a strategy of very high economic growth, with the objective of doubling gross domestic product in ten years. It recognises the central role the electricity sector has to play to achieve this target and has embarked on a highly ambitious program of electricity reform. If it is to succeed, the reform program will have to create market structures, market rules and a regulatory framework that will foster competitive wholesale and retail electricity markets. At the same time, it will have to deal with sensitive social issues related to tariff rebalancing and the removal of cross subsidies. Only competitive markets based on transparent prices that reflect costs can deliver the efficient, reliable and internationally competitive performance needed to meet the government's economic targets. Such markets are essential to attract new investment that will be required to ensure security of electricity supply after 2010. This book focuses on key aspects of the proposed reform that could have an important bearing on its success. It also raises concerns as to the pace of reform in related areas, such as the need for complementary reforms in the Russian natural gas sector. The IEA commends the Russian Government on its efforts to embrace this electricity reform - a key element critical to meeting the challenges ahead in terms of its economic growth and energy security. 17 figs., 10 tabs., 3 maps.

    2007-07-01

    India faces endemic electrical energy and peaking shortages. The Power Sector is plagued with mounting commercial losses due various inefficiencies, colossal commercial and technical losses and increasing subsidy burden on the states. These shortages have had a very detrimental effect on the overall economic growth of the country. In order to re-vitalise the sector and improve the techno-economic performance, the Government of India has initiated the reform process in 1991. This paper analyses the pre-reform era and identifies the key concerns which led to the initiation of the reforms. It also analyses the likely impact of the major policy and regulatory initiatives that have been undertaken since 1991 including the provisions of the new enactments which have come into force eventually in the form of The Electricity Act, 2003. This paper details out the key features of the Act and its likely impact on the Indian electricity industry in the emerging scenario. The paper also discusses major issues like power trading, role of regulator in the new regime, issue of open access, introduction of power markets and role of Appellate Tribunal for Electricity in harmonizing the orders of the various regulators.

    A mathematical model has been devised to represent the process that takes place in a fixed-bed, tubular, adiabatic catalytic reforming reactor. Since its development, the model has been applied to the simulation of a commercial semiregenerative reformer. The development of mass and energy balances for this reformer led to a model that predicts both concentration and temperature profiles along the reactor. A comparison of the model's results with experimental data illustrates its accuracy at predicting product profiles. Simple steps show how the model can be applied to simulate any fixed-bed catalytic reformer.

    The idea of spontaneous symmetry breaking as the mechanism through which elementary particles gain mass has been confirmed by the discovery of the Higgs boson at the CERN Large Hadron Collider. Studying the Higgs boson properties are of great importance to verify the Standard Model predictions. Any deviation from these predictions could uncover physics beyond the Standard Model. The mass of the Higgs boson is one of the important parameters of the Standard Model. The precise determination of the Higgs boson mass is of interest in its own right and also for other Higgs physics studies since it enters as parametric uncertainty into the extraction of the partial width from branching ratio measurements. The International Linear Collider (ILC) is a future polarised e + e - collider designed for precision physics studies. The Higgs boson decay to a pair of bottom quarks H→b anti b has the largest branching ratio of all Higgs decays, providing a large dataset for physics analyses. The possibility of measuring the Higgs boson mass in the e + e - →ZH→q anti qb anti b channel is investigated in this thesis for centre-of-mass energies of 350 GeV and 500 GeV. Since the Higgs boson mass is reconstructed from two b jets, the jet energy resolution hasa high impact on the measurement. A new method to estimate the jet energy resolution for each jet individually is developed in this thesis. The jet-specific energy resolution is then used in the analysis for the Higgs boson mass measurements. Various strategies for the Higgs boson mass measurement are investigated. For an integrated luminosity of 1000 fb -1 and a beam polarisation of (-0.8,+0.3), statistical uncertainties of 42 MeV and 89 MeV are achieved for the centre-of-mass energies of 350 GeV and 500 GeV, respectively.

    As global environment problems, there are water, expansion of deserts, weather, tropical forests, wild animals, ocean pollution, nuclear waste contamination, acid rain, ozone layer and so on, and population, foods, energy, and resources are the problems surrounding them. It is clear that these origins are attributed to the development and consumption largely dependent on the intention of developed countries and the population problem of developing countries. In this report, the discharge of carbon dioxide that causes greenhouse effect and its relation with energy are discussed. The increase of carbon dioxide concentration, its release from fossil fuel, the destruction of forests, the balance of carbon on the earth, the development of new energy such as solar energy, the transport of new energy, secondary energy system and the role of carbon dioxide, the transfer to low carbon fuel and the carbon reduction treatment of fuel, the utilization of unused energy and energy price, the efficiency of energy utilization, the heightening of efficiency of energy conversion, energy conservation and the breakaway from energy wasteful use culture, and the recovery, preservation and use of discharged carbon dioxide are described.

    A catalytic reforming method is disclosed herein. The method includes sequentially supplying a plurality of feedstocks of variable compositions to a reformer. The method further includes adding a respective predetermined co-reactant to each of the plurality of feedstocks to obtain a substantially constant output from the reformer for the plurality of feedstocks. The respective predetermined co-reactant is based on a C/H/O atomic composition for a respective one of the plurality of feedstocks and a predetermined C/H/O atomic composition for the substantially constant output.

  14. Adoption of energy-efficiency measures in SMEs—An empirical analysis based on energy audit data from Germany

    2012-01-01

    This paper empirically investigates factors driving the adoption of energy-efficiency measures by small and medium-sized enterprises (SMEs). Our analyses are based on cross-sectional data from SMEs which participated in a German energy audit program between 2008 and 2010. In general, our findings appear robust to alternative model specifications and are consistent with the theoretical and still scarce empirical literature on barriers to energy-efficiency in SMEs. More specifically, high investment costs, which are captured by subjective and objective proxies, appear to impede the adoption of energy-efficiency measures, even if these measures are deemed profitable. Similarly, we find that lack of capital slows the adoption of energy-efficiency measures, primarily for larger investments. Hence, investment subsidies or soft loans (for larger investments) may help accelerating the diffusion of energy-efficiency measures in SMEs. Other barriers were not found to be statistically significant. Finally, our findings provide evidence that the quality of energy audits affects the adoption of energy-efficiency measures. Hence, effective regulation should involve quality standards for energy audits, templates for audit reports or mandatory monitoring of energy audits. - Highlights: ► We empirically analyze barriers to the adoption of energy-efficiency measures in SMEs. ► We focus on firms participating in the German energy audit program for SMEs. ► The program overcomes information related barriers. ► High investment costs still impede the adoption even for profitable measures. ► Low audit quality also impedes the adoption of profitable measures.

  18. High temperature nuclear heat for isothermal reformer

    International Nuclear Information System (INIS)

    Epstein, M.

    2000-01-01

    High temperature nuclear heat can be used to operate a reformer with various feedstock materials. The product synthesis gas can be used not only as a source for hydrogen and as a feedstock for many essential chemical industries, such as ammonia and other products, but also for methanol and synthetic fuels. It can also be burnt directly in a combustion chamber of a gas turbine in an efficient combined cycle and generate electricity. In addition, it can be used as fuel for fuel cells. The reforming reaction is endothermic and the contribution of the nuclear energy to the calorific value of the final product (synthesis gas) is about 25%, compared to the calorific value of the feedstock reactants. If the feedstock is from fossil origin, the nuclear energy contributes to a substantial reduction in CO 2 emission to the atmosphere. The catalytic steam reforming of natural gas is the most common process. However, other feedstock materials, such as biogas, landfill gas and CO 2 -contaminated natural gas, can be reformed as well, either directly or with the addition of steam. The industrial steam reformers are generally fixed bed reactors, and their performance is strongly affected by the heat transfer from the furnace to the catalyst tubes. In top-fired as well as side-fired industrial configurations of steam reformers, the radiation is the main mechanism of heat transfer and convection heat transfer is negligible. The flames and the furnace gas constitute the main sources of the heat. In the nuclear reformers developed primarily in Germany, in connection with the EVA-ADAM project (closed cycle), the nuclear heat is transferred from the nuclear reactor coolant gas by convection, using a heating jacket around the reformer tubes. In this presentation it is proposed that the helium in a secondary loop, used to cool the nuclear reactor, will be employed to evaporate intermediate medium, such as sodium, zinc and aluminum chloride. Then, the vapors of the medium material transfer

  19. Measuring Energy Efficiency in China’s Transport Sector

    Directory of Open Access Journals (Sweden)

    Han Hao

    2017-05-01

    Full Text Available Energy efficiency is one of the key factors affecting energy consumption and greenhouse gas (GHG emissions. By focusing on China’s transport sector, this study comprehensively reviews and compares the energy efficiency performance of passenger vehicles, light-duty commercial vehicles, commercial road transport, commercial water transport, aviation transport and railway transport, and identifies the opportunities for further energy efficiency improvements. It is found that railway transport exhibited the greatest improvement in energy efficiency during the past decade, which was mainly driven by progress in its electrification. Passenger vehicles have also experienced considerable energy efficiency improvements, which can be mainly attributed to the establishment of mandatory fuel consumption standards. In contrast, commercial road transport has shown the least improvement, due to insufficient policy implementations. Based on the analysis, it is recommended that, as China’s present policy framework to improve energy efficiency in the transport sector is generally effective, it should be consistently maintained and successively improved. Electrification represents a major opportunity for improvement of energy efficiency in the transport sector. Such potential should be fully tapped for all transport modes. Greater effort should be put into improving the energy efficiency of commercial road transport. The policy instruments utilized to improve the energy efficiency of heavy-duty vehicles should be as intensive and effective as the policy instruments for passenger vehicles.

  20. Non-catalytic recuperative reformer

    Science.gov (United States)

    Khinkis, Mark J.; Kozlov, Aleksandr P.; Kurek, Harry

    2015-12-22

    A non-catalytic recuperative reformer has a flue gas flow path for conducting hot flue gas from a thermal process and a reforming mixture flow path for conducting a reforming mixture. At least a portion of the reforming mixture flow path is embedded in the flue gas flow path to permit heat transfer from the hot flue gas to the reforming mixture. The reforming mixture flow path contains substantially no material commonly used as a catalyst for reforming hydrocarbon fuel (e.g., nickel oxide, platinum group elements or rhenium), but instead the reforming mixture is reformed into a higher calorific fuel via reactions due to the heat transfer and residence time. In a preferred embodiment, extended surfaces of metal material such as stainless steel or metal alloy that are high in nickel content are included within at least a portion of the reforming mixture flow path.

    An experiment was conducted using a MEL (multi-energy laser) method in which multiple laser devices were operated for the formation of an ultra-hard surface reformed layer. At the first step of the research, a carbon-based material was irradiated with various laser beams in an CO2 gas atmosphere, and the hardness, Raman spectrum, etc., of the surface structure were evaluated. As the result, it was found that the formation of diamond like carbon (DLC) texture advances faster when the excited wavelength is longer from ArF laser toward SHG-YAG laser. At the second step, an effort was made to grow DLC out of tungsten carbide. When a normal pulse YAG laser beam was projected on a WC-Co substrate, W was dissociated on the surface for the precipitation of graphite. Next, XeCl excimer laser was projected on the precipitated graphite, and then the graphite was reformed into DLC. In this experiment, transition from graphite to DLC was controlled by changing the delay time lengths of the two laser beams. (NEDO)

    The current economic-political conditions in the oil market are spurring on future alternative energy models worldwide, one of which is fuel batteries. This technology is foreseen to have several applications in portable and stationary services. Previous studies have reported on the slowness of Mexican legislation, compared to international legislation, on the collection and treatment of spent domestic batteries. Legislation on the issue is limited to a project for a Non-Mandatory Mexican Norm proposed since 2006, without having been implemented at the time the present document was written. In addition to the toxic environmental impact of the lack of regulation, it also represents a waste of energy, impacting the finances of users who throw away batteries with a significant residual energy charge (>60 %). This work analyzes recent Mexican energy reform to regulate the use of alternative technologies. Compared to international legislation, the basis of the Mexican legislation is unclear and incomplete, lacking technological consulting from governmental scientific institutions and clear, complete legislation adhering to international principles for the environment and society. These characteristics pose a risk to regulations and their application in Mexican society, and involve a loss in the benefits of applying clean technologies having better performance, a continued reflection of slow technological, economic, environmental and social advancement.

    This final report for the Swiss Federal Office of Energy (SFOE) examines the effects of a future liberalisation of the gas market in Switzerland. The report first examines the current situation of the gas supply industry in Switzerland. The contents of European Union Guidelines are described and their implementation in Switzerland is discussed. Experience already gained in other countries is looked at, including market opening already implemented in the USA and Great Britain. The effect of market-opening on gas prices is discussed; the various components of the gas price are examined and comparisons are made with international figures. The pressure of competition on the individual sectors of the gas industry are looked at and the perspectives in the gas purchasing market are examined. The report presents basic scenarios developed from these considerations. Further effects resulting from a market opening are discussed, including those on the structure of the gas industry, its participants, electricity generation, energy use and the environment, consumers in general, security of supply and the national economy. Possible compensatory measures are discussed and factors for increasing efficiency and the promotion of a competitive environment are discussed. In the appendix, two price scenarios are presented

    The authors report here progress made during the three year period January 1, 1990, to December 31, 1993, for the Department of Energy Three-Year Grant No. DE-FG05-88ER40446, third year. A major part of the work has been associated with nucleon-nucleon (N-N) research carried out at the Nucleon Physics Laboratory (NPL) at the Los Alamos Meson Physics Facility (LAMPF). During this period they also completed data acquisition and analyses of a TRIUMF experiment, but they have no further plans for experimental work at TRIUMF. Other research has been and will be continued to be carried out at BNL, and involves two rare kaon decay experiments, BNL E791, now completed, and a second generation rare kaon decay experiment, E871, which has just this summer completed an engineering test run. The authors are now also members of a proposed experiment, STAR, (Solenoidal Tracker at RHIC) to be carried out at the Relativistic Heavy Ion Collider facility, RHIC, at BNL. The past three years have been a time of rapid change in the focus of the experimental program. A LAMPF experiment, E1097, in which they spent a large amount of effort during the past three years, was terminated due to funding shortages after they had fabricated the detector, but before data acquisition, and consequently they increased their participation in the rare kaon experiment at BNL, E871. It now appears that there will be no LAMPF N-N program after 1993, so that the research efforts will concentrate on the BNL rare kaon decay measurement, E871, and on STAR. The authors expect that STAR, which requires the fabrication of a large colliding beam detector facility, will use an increasing amount of their research efforts during the next few years. In what follows they describe recent progress on the LAMPF and TRIUMF N-N measurements, on the BNL rare kaon decay work, and on the initial work with the STAR group

    Although it has been adjusted six times since the year 2000, it has not yet been possible to manage the unrestricted growth of the EEG levy. In the 2017 election year, it becomes therefore ever more obvious that an alternative way to finance the energy transition is high on the political agenda. This would lead to significant changes for energy-intensive companies, regardless of whether they have benefited from a release from the levy or not. At the same time, the alternatives currently discussed have quite different effects on the industrial companies concerned and thereby the industry location Germany. [German] Obwohl seit dem Jahr 2000 inzwischen sechsmal angepasst, ist es bisher nicht gelungen, den ungebremsten Anstieg der EEG-Umlage in den Griff zu bekommen. Im Wahljahr 2017 wird deshalb immer offensichtlicher, dass ein alternativer Weg zur Finanzierung der Energiewende weit oben auf der politischen Tagesordnung steht. Damit kaemen auf die energieintensiven Unternehmen signifikante Veraenderungen zu, und zwar unabhaengig davon, ob sie bisher von einer Befreiung von der Umlage profitiert haben oder nicht. Dabei haben die derzeit diskutierten Alternativen durchaus unterschiedliche Auswirkungen auf die betroffenen Industrieunternehmen und damit den Wirtschaftsstandort Deutschland.

    At the macro-level it has long been accepted that there is a strong relationship between energy and economic growth (IDS, 2003). In the 1990s, the development discourse began to focus on the effects that economic growth has had on poverty. However, an interest in the links between energy and poverty

    Keppler, J.H.

    2007-01-01

    After having recalled a dozen of reasons for some worries about energy supply security in Europe during the past months (oil price increase, intentional interruption of gas and oil deliveries by Russia respectively to Ukraine and Belarus, creation of a new CO 2 trading scheme, tensions on the European electricity markets, and so on), the author distinguishes and discusses those which are actually a threat to energy supply and those which are not. Then, he proposes a classification of these threats in relationship with the reasons for delivery interruption, production capacity limitation, or price increase. These reasons can be political situations and decisions, technical problems, commercial reasons. Then, the author examines what European policy makers can do to manage these risks and ensure energy supply security. This needs economic as well as political responses, coherence between domestic energy policies and energy supply security, and an efficient foreign policy based on a multilateral approach

  20. Towards measurement and verification of energy performance under the framework of the European directive for energy performance of buildings

    International Nuclear Information System (INIS)

    Burman, Esfand; Mumovic, Dejan; Kimpian, Judit

    2014-01-01

    Directive 2002/91/EC of the European Parliament and Council on the Energy Performance of Buildings has led to major developments in energy policies followed by the EU Member States. The national energy performance targets for the built environment are mostly rooted in the Building Regulations that are shaped by this Directive. Article 3 of this Directive requires a methodology to calculate energy performance of buildings under standardised operating conditions. Overwhelming evidence suggests that actual energy performance is often significantly higher than this standardised and theoretical performance. The risk is national energy saving targets may not be achieved in practice. The UK evidence for the education and office sectors is presented in this paper. A measurement and verification plan is proposed to compare actual energy performance of a building with its theoretical performance using calibrated thermal modelling. Consequently, the intended vs. actual energy performance can be established under identical operating conditions. This can help identify the shortcomings of construction process and building procurement. Once energy performance gap is determined with reasonable accuracy and root causes identified, effective measures could be adopted to remedy or offset this gap. - Highlights: • Building energy performance gap is a negative externality that must be addressed. • A method is proposed to link actual performance to building compliance calculation. • Energy performance gap is divided into procurement and operational gaps. • This framework enables policy makers to measure and address procurement gap. • Building fine-tuning by construction teams could also narrow operational gap

    2009-11-01

    This paper presents findings on how consistent teachers' perceptions of their students, their own role in the classroom, and the reformed curriculum are with the actual implementation of the reformed curriculum in the classroom. This study shows that the five participating teachers were consistent with their perceptions and their actual behavior in the classroom. The teachers who were engaged in designing the curriculum demonstrated consistent reformed teaching views and behaviors. The degree to which the teachers viewed the curriculum as useful to them and their students was an indicator of how reformed their teaching was as measured by the Reformed Teaching Observation Protocol (RTOP) [1][2]. Finally, it was determined that faithful implementation of a curriculum can mean faithfully implementing the theoretical foundation of the curriculum materials during instruction instead of implementing every component or lesson of the reformed curriculum.

    In the present work it is showed the implementation of the plasma diagnostic technique through actinometry which allows to determine the absolute density of excited species. It is showed the range of the technique application, for the case of N 2 -H 2 mixtures plasmas used for the metals nitridation. The effects of magnetic field and the work pressure over ions energy were determined, using a Faraday cup type energy analyser. The results showed that in our device it is possible to vary such energy in a range between 10-45 eV, which amplify the range of applications perceptibly in comparison with another type of discharges.

    Highlights: • The most influential factors affecting China’s energy security are identified. • Fuzzy AHP is used to quantify the importance of influential factors. • Strategic measures for enhancing China’s energy security are prioritized. • Fuzzy AHP is used to determine the priorities of the strategic measures. - Abstract: This study investigates the most influential factors affecting China’s energy security. It also identifies the most effective strategic measures for enhancing it. Fuzzy AHP has been used to determine weights for ranking the importance of Chinese energy security factors, and it has also been used to determine the priorities of the strategic measures with respect to enhancing those same factors. The study argues that a low proportion of renewable energy penetration is the most severe factor threatening China’s energy security, and that conducting research and development on energy technologies and improving energy efficiency is the most salient, positive, and necessary strategic measure

    Calorimetric measurements of the total runaway electron energy are carried out using a reciprocating probe during induced TEXTOR disruptions. A comparison with the energy inferred from runaway energy spectra, which are measured with a scintillator probe, is used as an independent check of the results. A typical runaway current of 100 kA at TEXTOR contains 30 to 35 kJ of runaway energy. The dependencies of the runaway energy on the runaway current, the radial probe position, the toroidal magnetic field and the predisruptive plasma current are studied. The conversion efficiency of the magnetic plasma energy into runaway energy is calculated to be up to 26%.

  9. Active Market Share: measuring competitiveness in retail energy markets

    Loomis, D.; Malm, E.

    1999-01-01

    As retail electric and gas markets deregulate, market share measurement becomes critical for marketers, regulators, and incumbent utilities. Yet traditional market share measures miss important features of these network industries. In this paper we model provider choice in network industries and develop two alternate market share measures - The Active Market Share (AMS) and the New Mover Market Share (NMMS), that are based on 'active demand'. These measures are shown to provide more accurate real-time measures of market activity. The NMMS is a special case of the AMS which is easy to measure empirically. Numerical simulations are used to provide comparisons between each measure over time. Both the AMS and NMMS will be important tools for anyone interested in measuring the competitiveness of deregulating markets. (author)

  10. Making the link: climate policy and the reform of the UK construction industry

    International Nuclear Information System (INIS)

    Sorrell, Steve

    2003-01-01

    This paper explores the barriers to energy efficiency in the construction of non-domestic buildings in the UK. The source of the barriers is argued to lie in the organisation of the construction industry, including the linear design process, the reliance on cost-based competitive tendering and the incentives placed upon different actors. The consequences include oversizing of equipment, reduced quality, neglect of whole life costs and lack of integrated design. Each of these problems can usefully be interpreted using concepts from the new institutional economics. While the barriers are well known to construction industry specialists, they are relatively neglected in the academic literature on energy policy. Furthermore, conventional policy measures such as building regulations leave these barriers largely untouched. The UK construction industry is currently undergoing a series of reforms which aim to change the relationship between different actors and to achieve improvements in product quality and productivity. While these reforms have the potential to address many of the barriers, the reform agenda makes practically no reference to sustainability. This paper argues that climate policy objectives must be integrated into the reform agenda if the UK is to begin the transition to a low carbon built environment

    Energy efficiency improvement leads to a reduction in the real cost of energy services per unit, thus bringing about an increase in the demand for energy services. Therefore, the potential energy savings and emission reduction from efficiency improvements might be offset, which is known as “the rebound effect”. This study disaggregates the effect into the direct and indirect effects based on the Slutsky Equation and finds that the rebound effect of Chinese urban households is approximately 22%. It is found that the indirect effect is stronger than the direct effect. These findings prove that the initial goals of the government on energy conservation and emission reduction could not be achieved by improving energy efficiency alone, but need to be supplemented with relevant energy pricing reforms. - Highlights: • This study disaggregates the effect into the direct and indirect effects. • The rebound effect of Chinese urban households is approximately 22%. • The indirect effect is stronger than the direct effect. • Energy pricing reform is needed to mitigate the rebound effect

    This report represents the national case study of Norway for the EIE-project 'Monitoring of Energy Demand Trends and Energy Efficiency in the EU - ODYSSEE-MURE'. It presents the recent energy efficiency trends in Norway on the basis of indicators extracted from the ODYSSEE database. Total energy consumption (not including energy as feedstock) has increased from 16.6 M toe (195 TWh) in 1990 to 19.2 M toe (226 TWh) in 2007 and has been relatively constant the last ten years. Energy consumption in manufacturing industry has increased by 10 % from 1990 to 2007, but is lower in 2007 than in 1998. Final energy use in households has increased from 3515 k toe (41 TWh) in 1990 to 3826 (45 TWh) in 2007. The climate corrected energy use has been at approximately 4000 k toe since the mid 1990s. It seems to be an interrupt in the increase of energy use in households, despite the growth of all common used drivers in this sector. Energy efficiency policies and measures implemented since 1990 have contributed to improve the efficiency by 13 %, or 0.7 % per year; this means that if these policies and measures would not have been implemented, the final energy consumption would have been 13 % higher in 2007 (or approximately 1.9 M toe or 22 TWh).

    Using computer simulation of a solvent-free, coarse-grained model for amphiphilic membranes, we study the excess free energy of hourglass-shaped connections (i.e., stalks) between two apposed bilayer membranes. In order to calculate the free energy by simulation in the canonical ensemble, we reversibly transfer two apposed bilayers into a configuration with a stalk in three steps. First, we gradually replace the intermolecular interactions by an external, ordering field. The latter is chosen such that the structure of the non-interacting system in this field closely resembles the structure of the original, interacting system in the absence of the external field. The absence of structural changes along this path suggests that it is reversible; a fact which is confirmed by expanded-ensemble simulations. Second, the external, ordering field is changed as to transform the non-interacting system from the apposed bilayer structure to two-bilayers connected by a stalk. The final external field is chosen such that the structure of the non-interacting system resembles the structure of the stalk in the interacting system without a field. On the third branch of the transformation path, we reversibly replace the external, ordering field by non-bonded interactions. Using expanded-ensemble techniques, the free energy change along this reversible path can be obtained with an accuracy of 10(-3)k(B)T per molecule in the n VT-ensemble. Calculating the chemical potential, we obtain the free energy of a stalk in the grandcanonical ensemble, and employing semi-grandcanonical techniques, we calculate the change of the excess free energy upon altering the molecular architecture. This computational strategy can be applied to compute the free energy of self-assembled phases in lipid and copolymer systems, and the excess free energy of defects or interfaces.

    Lampl, W.

    2005-12-01

    This PhD-thesis addresses the calibration of the ATLAS electromagnetic calorimeter. ATLAS is a high-energy physics experiment at the Large Hadron Collider (LHC) which is currently under construction at CERN in Geneva. LHC and ATLAS are foreseen to start up in 2007. In summer 2004, an extensive beam-test was carried out. This means that individual detector modules are exposed to a particle beam of known energy in order to verify the detector performance. At this occasion, all ATLAS subdetectors where operated together for the first time. The thesis contains a comprehensive description of the ATLAS electromagnetic calorimeter, the reconstruction software and the test-beam experiment that was carried out at CERN in 2004. Furthermore, the physics of the electromagnetic shower is discussed in detail. Data from the test beam as well as a detailed Monte-Carlo simulation are used to develop a novel energy-reconstruction method for the ATLAS EM calorimeter that achieves an excellent energy resolution (sampling term ∼ 11 %) as well as a very good linearity (< 0.4 %). Data taken during the beam test is also used to verify the accuracy of the simulation and to test the new energy-reconstruction method. (author)

    The effect of a stochastic background of cosmological perturbations on the luminosity-redshift relation is computed to second order through a recently proposed covariant and gauge-invariant light-cone averaging procedure. The resulting expressions are free from both ultraviolet and infrared divergences, implying that such perturbations cannot mimic a sizable fraction of dark energy. Different averages are estimated and depend on the particular function of the luminosity distance being averaged. The energy flux being minimally affected by perturbations at large z is proposed as the best choice for precision estimates of dark-energy parameters. Nonetheless, its irreducible (stochastic) variance induces statistical errors on Ω(Λ)(z) typically lying in the few-percent range.

    2006-01-01

    The inherent limitation in performance of building envelop components and heating ventilating and air conditioning (HVAC) equipment necessitates the examination of operational strategies for improvement in energy-efficient operation of buildings. Due to the ease of installation and increasing availability of electronic controllers, operational strategies that could be programmed are of particular interest. The Iowa Energy Center in the US has taken the initiative to conduct the necessary assessment of current HVAC technology and the commonly-used operational strategies for commercial and industrial buildings, as applied to the midwestern part of the country, with weather and energy cost data for Des Moines, Iowa. The first part of this study focused on the energy consumption and cost effectiveness of HVAC systems. The objectives of the second part is concerned with examination of various operational strategies, namely, night purge (NP), fan optimum start and stop (OSS), condenser water reset (CWR), and chilled water reset (CHWR) applied to order and newer-type commercial office buildings. The indoor air quality requirement are met and the latest applicable energy rates from local utility companies are used. The results show that, in general, NP is not an effective strategy in buildings with low thermal mass storage, OSS reduced fan energy, and CWR and CHWR could be effective and require chillers with multi-stage unloading characteristics. The most operationally efficient strategies are the combination of OSS, CWR, and CHWR for the older-type building, and OSS for the newer-type building. Economically, the most effective is the OSS strategy for the older-type building and the CHWR strategy for the newer-type building.(Author)
