Full Text Available The purpose of this study was to determine the level of knowledge and application of the management process in microenterprises of the southern Isthmus of Tehuantepec, Mexico. This is intended to generate inputs to the transformation of microenterprises into better equipped, innovative and job-generating organizations in a highly competitive global context. The methodological strategy of this research was to gather information via a stratified sample of the management functions: planning, organizing, directing and controlling. The results indicate that the level of education and age of microentrepreneurs are the most significant variables to explain the different levels of the management process. In addition, the detected deficiencies in the administrative functions within the microenterprises of the southern Isthmus of Tehuantepec are consistent with their life expectancies, which do not exceed four years.

Full Text Available The study examined the relationship between microcredit, microenterprises, and the social welfare of the rural poor in north-eastern Trinidad. Guided by the main propositions of social capital theory, the researchers held 45 semi-structured interviews with active participants/clients within a case study research design. The data showed that access to microcredit through Helping Others Prosper Economically (HOPE positively affected their microenterprises and social welfare, though marginally. Findings also revealed that fragmented social relations within the network, conflict, distrust, and the loose structure of the program limited the impact of their access to microcredit on social welfare as well as the financial potential of the lending organisation, that is, HOPE. It is the contention of this paper, therefore, that such questionable social relations dynamics 'hijack' the promise of collective social networks as exercised through goodwill and resource building. Implications of this study and directions for future research are discussed.

Grameen Bank`s experience with energy related microenterprise development

Energy Technology Data Exchange (ETDEWEB)

Barua, D.C.

1997-12-01

Increased population and growth of industry have resulted in greater demand for energy worldwide. Most of this energy is derived from fossil fuel (coal, gas, oil and nuclear) which will soon be depleted. In this context the need for developing renewable sources of energy has taken on a greater sense of importance and urgency. Over the years significant technological advances have been made in the area of renewable energies especially in the field of solar photovoltaics (PV), wind energy and bio-gas technology. In addition, for remote rural areas where there exists no infrastructure for conventional energy supply, these forms of decentralized alternative energy systems will be far more adaptable and well suited. Grameen Shakti (Energy) is an addition to the family of companies of Grameen Bank, to promote and supply renewable energy sources to rural households. GS, a not-for-profit company, expects not only to supply renewable energy services, but also to create employment and income generation opportunities in rural Bangladesh. GS will focus on supply, marketing, sales, testing and development of renewable energy systems of solar pv, biogas, wind turbines and windpumps.

Full Text Available In modern world, big changes are occurring in short time frames, business are dealing with information and communication technologies adaptation and updating problems, being such as Internet and Web 2.0. There are different tools that allow efficiency in internal and external communications of the company; when it comes to external communication, digital marketing is gaining more ground and an increasing number of companies invest more in that kind of strategies. Digital marketing as a tool for business is a great advantage that not all recognize, even much less number of companies use it, in particular microenterprises. There are many factors that influence the decision to adopt digital marketing strategies and activities. The present paper presents the scores for the different digital marketing activities as perceived and implemented by micro-enterprises in the city of Tijuana. The main reasons why they do not perform digital marketing activities are: they do not believe it necessary, training outdates and price. Companies mainly perform activities in social networks, in the company website, emailing and online advertising, while they qualify email, website, Facebook and Google Maps as the most useful digital marketing activities. This information can be used both by microenterprises as by suppliers to generate profitable strategic alliances.

Abstract In European countries, the majority of the total value of exports comes from small, medium-sized and large enterprises, because they tend to be the principal target groups of public-support actions related to exports. However, micro-sized enterprises are the most numerous in every European economy. In recent years, global digitalization has lowered the barriers to exporting for micro-enterprises, and as a result, their share of total exports have increased rapidly in many countrie...

Nursing has been a leader in exploring social determinants of health within the context of U.S. microenterprise and women's health. The purpose of this study was to explore precarious employment within the context of microenterprise and women's health using focus groups with clientele from New Mexico (NM). The specific aims were to identify (1) the health concerns of low-income women who utilized resources from Women's Economic Self-Sufficiency Team (WESST), and (2) the meaning of precarious employment in low-income women's lives. Fourteen women, ranging in age from 21-65 years, who were affiliated with regional WESST sites around NM participated in focus groups and completed a demographic questionnaire. Focus group data were analyzed using content analysis. The degree of interrater agreement was determined by calculating the Cohen's kappa, percentage agreement, and prevalence-adjusted and bias-adjusted kappa (PABAK). Two broad themes emerged from these data: (1) Working for Yourself and (2) Strategies. Although the women identified concerns about participation in microenterprise, flexibility, freedom, and feeling purposeful were motivators to pursue a small business. The kappa statistics on the five transcripts revealed poor inter-rater agreement, yet PABAK, which is a more sophisticated inter-rater reliability index, indicated that inter-rater agreement between the two raters was satisfactory. Despite the challenges associated with microenterprise in the US, women found value in working for themselves. © 2014 Wiley Periodicals, Inc.

Examining the effectiveness of micro-enterprise development programs in Malaysia

Full Text Available Previous studies on socioeconomic development have examined the effect of development initiatives (i.e., access to finance and training on several socioeconomic indicators (i.e., income, empowerment, asset, quality of life, employment. These studies have focused mostly on the outcomes of specific types of programs offered by specific development organizations. This study however focuses on informal women micro-entrepreneurs’ participation in various development programs available to them and their influence on entrepreneurial competencies, human capital development, competitive advantages, economic vulnerability, supportive environment, and performance of micro-enterprises. This cross-sectional study adopted the purposive random sampling method and collected data from 384 informal women entrepreneurs from the local markets in different districts of Kelantan, Malaysia. The findings show that the development program participants have relatively higher levels of entrepreneurial competencies, human capital development, and higher levels of enterprise performance compared to non-participants. It is also noted that the level of economic vulnerability is relatively low among participants compared to non-participants. However, these findings contradict most of the earlier studies that show a significant positive impact of micro-credit on socio-economic wellbeing, as the difference in entrepreneurial competencies, human capital development, economic vulnerability, and performance of micro-enterprises among participants and non-participants in this study is not statistically significant. However, findings reported significantly higher levels of competitive advantages, and better supportive environment among the participants compared to the non-participants. Development organizations should therefore focus on expanding their outreach to spread the positive effects of their development programs towards uplifting the economic condition of low and middle

2014-05-01

Full Text Available The objective of this research was to explore, both theoretically and empirically, the ecological impacts of small-scale entrepreneurial ventures in developing countries. To this end, six microenterprises in rural southwestern Bangladesh established using green-microcredit strategies were evaluated in terms of goals, operational procedures, economic viability, social contributions, and impact on local ecological sustainability. This research revealed that the majority of such enterprises are not only sustainable and comply with current ecological standards, but also contribute a considerable number of vital ecosystem services while simultaneously maintaining suitably high profit margins to promise long-term economic viability. These findings indicate that microenterprises given environmental guidance by developmental non-governmental organizations (NGOs—especially NGOs microfinance institutions, NGO-MFIs—have the potential to make significant ecological contributions and address the issue of climate change from the bottom of the social ladder upwards.

Micro-enterprise predicament in township economic development: Evidence from Ivory Park and Tembisa

Andrew Charman

2017-05-01

Aim: In response to the developmental need to stimulate micro-enterprise growth in South African townships, the paper poses the question: what approaches are most likely to have a positive impact on township businesses, given current micro-enterprise dynamics? Setting: Primary research was undertaken in two neighbouring townships in Gauteng province, in Ivory Park and Tembisa. Methods: The data comprises a geospatial census of enterprise activities, a survey of select firms and qualitative interviews with business owners. The research utilised a small-area census approach to obtain data on business activities within an area of approximately 2km2 in each site. The census enumerated 2509 micro-enterprises in Ivory Park and 1722 micro-enterprises in Tembisa. Firm interviews were conducted with business owners in four sectors: grocery retail, liquor retail, hair care and early childhood development centres. Results: The business census identifies a strong similarity in the structure of the townships’ informal micro-entrepreneurship despite the considerable differences in the socio-economic status of the respective case sites. The enterprise survey highlights the resource constraints of township businesses and thinness of local markets. Interviews with entrepreneurs reveal four main pathways through which individuals enter into self-employment with the most dynamic enterprises established by inward investing entrepreneurs. Spatial considerations exert an influence on the position of enterprise sectors, whilst access to land and business infrastructure are notable constraints. Conclusion: Reflecting on the evidence, the paper concludes with making a call for a more low-geared development approach, focusing on lessening the legal, institutional and regulatory obstacles to enterprise growth as a first step. Municipalities have an important role in liberalising the spaces and places where township informal enterprises can and should be permitted to trade as well as

With the evolution of the Internet and smartphone devices, Internet advertising has become one of the most important methods for delivering promotional marketing messages to customers. However, the efficiency of Internet advertising for microenterprise is not very high, since Wi-Fi advertising-which is limited by a small router coverage area-is mainly used. Moreover, because of the lack of money, microenterprises have been using low-cost methods to promote their products. Thus, enhancing the effectiveness of Wi-Fi advertising, and solving the problem of cost and the range of the views are now an essential investigation in this study. In this paper, we propose a reciprocal model with Wi-Fi union mechanism for Internet advertising based on fog computing architecture to enhance the efficiency of advertisement, reduce the cost, and increase the range of the views for microenterprise by using the Internet. In particular, the system was built in advertisers', publishers', and consumers' sides. In our system, we use contribution point (CP) as an exchange value among the participants. Advertisers and publishers can get CP by helping the others in the system to promote their advertisements, increasing their CP by one unit. Similarly, advertisers and publishers can use their CP to ask for assistance from the others, decreasing their CP by one unit. The result shows that the system in a Wi-Fi union is easy to use, and advertisements can be seen by all customers who are using free Wi-Fi from the stores of the union. This method can solve the problem of cost and fixed consumer groups.

Full Text Available A loyal customer costs less to retain than acquiring a new customer. Loyal customers stick to the same service provider for a longer time period. Thus, the ultimate aim of the management of any organisation must be to create an emotional bonding with the customerto a level of much more than business considerations, to be able to sustain the loyalty for a long period of time. A number of service providers are available for any organisation for anything it requires, particularly in banking and financial institutions. The choice of the micro-enterprise as banks business client is influenced by a number of factors such as Service Quality, Reputation and Relationship with a brand or an organisation. Apart from that, there are a number of other factors which can affect the choice of a service provider such as factors based on emotional considerations particularly cultural elements. This paper integrates previous research in the field of customer loyalty to present a conceptual framework of micro-enterprises owners’ loyalty and its underlying drivers. Implication for the future research directions is also presented.

‘Is It Entrepreneurship, or Is It Survival?’: Gender, Community, and Innovation in Boston’s Black Immigrant Micro-Enterprise Spaces

Directory of Open Access Journals (Sweden)

Ping-Ann Addo

2017-08-01

Full Text Available Micro-enterprises are typically classified as businesses with fewer than six employees and very small amounts of financial capital. Focusing on black immigrant women’s micro-entrepreneurial ventures in Boston, this paper explores how non-economic forms of capital are crucial to the survival of micro-enterprise, in large part because of customer choices to patronize businesses they trust and to support proprietors whose identities and values they share. The richness of social and cultural capital and local information—controlled by minority immigrant women micro-entrepreneurs—can easily go undetected by mainstream lenders, training programs, and policy-makers. Other features that go unnoticed include the fact that the proprietors and patrons of micro-enterprises can often be highly skilled and educated and that innovative business moves are often embodied in already-existing processes of reciprocity and exchange. With implications for how funding can be infused into communities deeply connected to informal economy processes in U.S. cities, the paper argues for support for community-based processes of local development, economic growth, and social justice that are rooted in the communities that need them.

Globalisation and increasing requirements of the environment cause the executives and supervisors to search for more and more perfect solutions, allowing them to streamline and improve the effectiveness of company operations. One of such tools, used more and more often, is controlling, the role of which has substantially increased in the recent years. It is already implemented not only in large companies with foreign capital, but also in increasingly smaller entities, which begin to notice the positive effects of the implications of the principles and tools of controlling - both operational and strategic. The purpose of the article is to demonstrate the practical side of controlling tools that can be used for the purposes of operations conducted by microenterprises.

Do men need empowering too? A systematic review of entrepreneurial education and microenterprise development on health disparities among inner-city black male youth.

2014-10-01

Economic strengthening through entrepreneurial and microenterprise development has been shown to mitigate poverty-based health disparities in developing countries. Yet, little is known regarding the impact of similar approaches on disadvantaged U.S. populations, particularly inner-city African-American male youth disproportionately affected by poverty, unemployment, and adverse health outcomes. A systematic literature review was conducted to guide programming and research in this area. Eligible studies were those published in English from 2003 to 2014 which evaluated an entrepreneurial and microenterprise initiative targeting inner-city youth, aged 15 to 24, and which did not exclude male participants. Peer-reviewed publications were identified from two electronic bibliographic databases. A manual search was conducted among web-based gray literature and registered trials not yet published. Among the 26 papers retrieved for review, six met the inclusion criteria and were retained for analysis. None of the 16 registered microenterprise trials were being conducted among disadvantaged populations in the U.S. The available literature suggests that entrepreneurial and microenterprise programs can positively impact youth's economic and psychosocial functioning and result in healthier decision-making. Young black men specifically benefited from increased autonomy, engagement, and risk avoidance. However, such programs are vastly underutilized among U.S. minority youth, and the current evidence is insufficiently descriptive or rigorous to draw definitive conclusions. Many programs described challenges in securing adequate resources, recruiting minority male youth, and sustaining community buy-in. There is an urgent need to increase implementation and evaluation efforts, using innovative and rigorous designs, to improve the low status of greater numbers of African-American male youth.

Microcredit and Survival Microenterprises: The Role of Market Structure

Directory of Open Access Journals (Sweden)

P. V. Viswanath

2017-12-01

Full Text Available Poverty remains a pervasive problem all over the world, but the problem is worst in underdeveloped areas like Africa. While microfinance is supposed to address this problem through the promotion of viable businesses, it has not been very successful in helping survival microenterprises, i.e., businesses that the very poor with limited human capital have access to, in sectors with low barriers to entry and selling undifferentiated products. In this paper, I examine the role of market structure in mediating the impact of micro-lending to such survival enterprises. While there have been many evaluations of microfinance institutions (MFIs, there have been very few that look at market conditions as an input into the success of micro-lending. My theoretical analysis suggests that when introducing an extensive program of microcredit in undeveloped and relatively isolated rural areas, it is important to look at how the market structure mediates the impact of the provision of loans on the demand and supply for the end-product or service. I present some empirical evidence, which provides partial confirmation that MFIs are not currently taking these considerations into account.

The need to use elements of controlling system by entities of small and microenterprises

Full Text Available The entities of small and microenterprise are the basis of an effectively functioning market economy. The development of small business in Ukraine is hindered by a number of negative factors, one of them is the imperfection of the management system. An effective method of improving the management system is the use of controlling as one of the newest technologies for coordinating managerial and economic processes towards achieving the general goals of the business entity. The article is devoted to the substantiation of the need to use elements of the controlling system at microenterpreneurship enterprises, to identify elements that are subject to urgent implementation and to determine effective approaches to the practical implementation of selected elements. The controlling system is primarily used to coordinate the management process in complex organizational structures that are characteristic of large and medium-sized enterprises, but some of its elements can be effectively used by small and microenterprises. The authors substantiate the necessity of introducing the following elements of the controlling system by small business entities: management accounting, monitoring, cost-benefit analysis, the information support for management decisions. The introduction of these elements is appropriate with the use of outsourcing or co-sourcing. The consultative and professional support of these processes should be provided by local government authorities as one of the directions of the state program for supporting small business.

Unseen influence—The role of low carbon retrofit advisers and installers in the adoption and use of domestic energy technology

International Nuclear Information System (INIS)

Owen, A.; Mitchell, G.; Gouldson, A.

2014-01-01

Reducing climate changing emissions associated with residential property continues to be a significant challenge. Five case studies of different domestic energy technology schemes in England highlight the influence of advisers and installers in householders’ decisions to adopt low carbon technologies. Many of these advisers and installers are micro-enterprises working in connected groups in particular geographic areas. Such micro-enterprises form a large part of the construction sector, but despite the number of enterprises and the potential impact of changes in the behaviour of the sole traders and small firms, there appears to be little policy that specifically targets this group. Data from these case studies is presented and organised into a typological framework, in order to illustrate the range of ways in which the impact of advisers and installers can be modified. Two of the six factors in the typological framework relate to the motivation of installers themselves and how their work is perceived by their clients. By examining these factors in particular, this paper makes a novel contribution to understanding the factors that influence the take up and use of domestic energy technologies, leading to the possibility of new policy options or interventions. - Highlights: • Five UK schemes to promote domestic energy technology are examined. • Advisers and installers influence the impact of energy technology. • Micro-enterprises dominate low carbon retrofit. • Low carbon retrofit installers are beyond the reach of current policy. • A framework for investigating installer competence is proposed

Risk assessment is the fundamental process of an enterprise's prevention system and is the principal mandatory provision contained in the Health and Safety Law (Legislative Decree 81/2008) amended by Legislative Decree 106/2009. In order to properly comply with this obligation also in small-sized enterprises, the appropriate regulatory bodies should provide the enterprises with standardized tools and methods for identifying, assessing and managing risks. To assist in particular small and micro-enterprises (SMEs) with risk assessment, by providing a flexible tool that can also be standardized in the form of a datasheet, that can be updated with more detailed information on the various work contexts in Italy. Official efforts to provide Italian SMEs with information may initially make use of the findings of research conducted by ISPESL over the past 20 years, thanks in part to cooperation with other institutions (Regions, INAIL-National Insurance Institute for Occupational Accidents and Diseases), which have led to the creation of an information system on prevention consisting of numerous databases, both statistical and documental ("National System of Surveillance on fatal and serious accidents", "National System of Surveillance on work-related diseases", "Sector hazard profiles" database, "Solutions and Best Practices" database, "Technical Guidelines" database, "Training packages for prevention professionals in enterprises" database). With regard to evaluation criteria applicable within the enterprise, the possibility of combining traditional and uniform areas of assessment (by sector or by risk factor) with assessments by job/occupation has become possible thanks to the cooperation agreement made in 2009 by ISPESL, the ILO (International Labour Organisation) of Geneva and IIOSH (Israel Institute for Occupational Health and Hygiene) regarding the creation of an international Database (HDODB) based on risk datasheets per occupation. The project sets out to assist in

Modern energy access to all in rural India: An integrated implementation strategy

International Nuclear Information System (INIS)

Balachandra, P.

2011-01-01

Expanding energy access to the rural population of India presents a critical challenge for its government. The presence of 364 million people without access to electricity and 726 million who rely on biomass for cooking indicate both the failure of past policies and programs, and the need for a radical redesign of the current system. We propose an integrated implementation framework with recommendations for adopting business principles with innovative institutional, regulatory, financing and delivery mechanisms. The framework entails establishment of rural energy access authorities and energy access funds, both at the national and regional levels, to be empowered with enabling regulatory policies, capital resources and the support of multi-stakeholder partnership. These institutions are expected to design, lead, manage and monitor the rural energy interventions. At the other end, trained entrepreneurs would be expected to establish bioenergy-based micro-enterprises that will produce and distribute energy carriers to rural households at an affordable cost. The ESCOs will function as intermediaries between these enterprises and the international carbon market both in aggregating carbon credits and in trading them under CDM. If implemented, such a program could address the challenges of rural energy empowerment by creating access to modern energy carriers and climate change mitigation. - Highlights: ► Expanding rural energy access in India is critical with majority lacking access to modern energy. ► Innovative and integrated implementation strategy for achieving universal rural energy access. ► Design of an integrated rural energy policy and proposal for new institutional mechanism. ► Establishing rural energy access authorities and energy access funds as supporting mechanisms. ► Bioenergy-based micro-enterprises for delivering energy services at an affordable cost.

Improving market access opportunities for urban small, medium and micro-enterprises in South Africa

Christian M. Rogerson

2013-01-01

Full Text Available Since the democratic transition of 1994, the promotion of the small, medium and micro-enterprise (SMME economy has been a core focus of South African government policy. With high levels of unemployment and poverty in urban areas, the impact of this policy intervention is most critical for city development. Given South Africa’s chequered history, the national government’s focus is on transforming the prospects for enterprises owned by black South Africans, who were disadvantaged under apartheid. This article examines the range of contemporary policy initiatives to address business constraints on market access and catalyse new market opportunities for black-owned enterprises in urban South Africa. The article concentrates on two themes: 1 building links into private sector supply chains, especially through supplier diversity, and 2 building links into public sector markets through public procurement. It is shown that current policy directions recognise that the national government has a limited capacity to implement SMME improvement and build competitive black-owned SMMEs by itself, which has prompted support for private sector initiatives. In addition, the government is struggling to practice what it preaches and use its own procurement capacity to assist black-owned SMMEs.

In spite of the intention of governments to increase the use of renewable energy in electricity supply, particularly the use of solar photovoltaic (PV) for energy poverty reduction in rural and peri-urban areas of Africa, there is relatively little information on how solar PV electrification impacts on energy poverty reduction. Therefore, there is a gap in the literature and hence the need for continuous research. Using Ghana as a reference country, the historical trend, donor cooperation and other aspects of solar PV rural electrification are discussed. The paper illustrates the intersectoral linkages of solar PV electrification and indicators on education, health, information acquisition, agriculture and micro-enterprises. It also reviews sustainability related issues including costs and market barriers, subsidies, stakeholders involvement, political and policy implications, which are critical factors for sustainable market development of solar PV and other renewables. Finally, a common framework is developed to provide a basic understanding of how solar PV electrification impacts on energy-poverty. This framework provides a structure of the interrelated concepts and principles relevant to the issues under review. (orig.)

A Living Lab as a Service: Creating Value for Micro-enterprises through Collaboration and Innovation

2013-11-01

Full Text Available The need to innovate is increasingly important for all types and sizes of organizations, but the opportunities for innovation differ substantially between them. For micro-, small,- and medium-sized enterprises, innovation activities are both crucial and demanding because of limited resources, competencies, or vision to innovate their offerings. To support these organizations, the concept of living labs as a service has started to emerge. This concept refers to living labs offering services such as designing the idea-generation processes, planning or carrying out real-world tests of innovations, and pre-market launch assessments. In this article, we will present the findings from a study of micro-enterprises operating in the information technology development sector, including the experienced value of services provided to the companies by a research-based living lab. We share experiences from Botnia, our own living lab in northern Sweden. In this living lab, our aim of creating value for customers is of key importance. Our study shows that using a living lab as a service can generate three different types of value: improved innovations, the role the living lab can play, and the support the living lab offers.

DOE/NREL supported wind energy activities in Indonesia

Drouilhet, S.

1997-12-01

This paper describes three wind energy related projects which are underway in Indonesia. The first is a USAID/Winrock Wind for Island and Nongovernmental Development (WIND) project. The objectives of this project are to train local nongovernmental organizations (NGOs) in the siting, installation, operation, and maintenance of small wind turbines. Then to install up to 20 wind systems to provide electric power for productive end uses while creating micro-enterprises which will generate enough revenue to sustain the wind energy systems. The second project is a joint Community Power Corporation/PLN (Indonesian National Electric Utility) case study of hybrid power systems in village settings. The objective is to evaluate the economic viability of various hybrid power options for several different situations involving wind/photovoltaics/batteries/diesel. The third project is a World Bank/PLN preliminary market assessment for wind/diesel hybrid systems. The objective is to estimate the size of the total potential market for wind/diesel hybrid power systems in Indonesia. The study will examine both wind retrofits to existing diesel mini-grids and new wind-diesel plants in currently unelectrified villages.

Family-based traditional microenterprises are abundant in developing countries, and in many cases they are a major source of income and employment for both urban and rural poor. With a few exceptions, however, most these family-based traditional microenterprises in the rural areas of developing countries seldom grow in terms of enterprises’ size and product quality. Thus, they tend to perform poorly relative to their growth potentials. The development of these family-based microenterprises wo...

Protocols of quantum energy teleportation (QET), while retaining causality and local energy conservation, enable the transportation of energy from a subsystem of a many-body quantum system to a distant subsystem by local operations and classical communication through ground-state entanglement. We prove two energy-entanglement inequalities for a minimal QET model. These relations help us to gain a profound understanding of entanglement itself as a physical resource by relating entanglement to energy as an evident physical resource.

Energy-range relation and mean energy variation in therapeutic particle beams

International Nuclear Information System (INIS)

Kempe, Johanna; Brahme, Anders

2008-01-01

Analytical expressions for the mean energy and range of therapeutic light ion beams and low- and high-energy electrons have been derived, based on the energy dependence of their respective stopping powers. The new mean energy and range relations are power-law expressions relevant for light ion radiation therapy, and are based on measured practical ranges or known tabulated stopping powers and ranges for the relevant incident particle energies. A practical extrapolated range, R p , for light ions was defined, similar to that of electrons, which is very closely related to the extrapolated range of the primary ions. A universal energy-range relation for light ions and electrons that is valid for all material mixtures and compounds has been developed. The new relation can be expressed in terms of the range for protons and alpha particles, and is found to agree closely with experimental data in low atomic number media and when the difference in the mean ionization energy is low. The variation of the mean energy with depth and the new energy-range relation are useful for accurate stopping power and mass scattering power calculations, as well as for general particle transport and dosimetry applications

Solar-Based Rural Electrification and Micro-Enterprise Development in Latin America: A Gender Analysis

Energy Technology Data Exchange (ETDEWEB)

Smith, J.

2000-11-16

Worldwide, an estimated 1.5 to 2 billion people do not have access to electricity, including 100 million in the Latin America region. Depending on the country, 30 to 90% of this unelectrified Latin American population lives in rural areas where geographic remoteness and low energy consumption patterns may preclude the extension of the conventional electricity grid. Women are heavily impacted by the energy scarcity given their role as primary energy procurers and users for the household, agricultural and small industrial subsectors in developing countries. As a result, women spend disproportionately more time engaged in energy-related activities like carrying water and searching for cooking fuel. This paper describes the use of decentralized renewable energy systems as one approach to meet the energy needs of rural areas in Latin America. It outlines the advantages of a decentralized energy paradigm to achieve international development goals, especially as they relate to women. The paper studies Enersol Associates, Inc.'s Solar-Based Rural Electrification model as an example of a decentralized energy program which has merged energy and development needs through the local involvement of energy entrepreneurs, non-governmental organizations and community members.

Energy Vulnerability and EU-Russia Energy Relations

Directory of Open Access Journals (Sweden)

Edward Hunter Christie

2009-08-01

Full Text Available The concept of energy vulnerability is reviewed and discussed with a focus on Russia’s foreign energy relations, in particular those with European countries. A definition and a conceptual framework for quantifying energy vulnerability are proposed in the context of a review of recent research on energy vulnerability indices. In particular it is suggested that source country diversification should be reflected using the expected shortfall measure used in financial economics, rather than the Herfindahl-Hirschman or Shannon-Wiener indices, and that the former should then enter a calibrated function in order to yield expected economic loss. The issues of asymmetric failure probabilities and accidental versus intentional supply disruptions are then discussed with examples of recent Russian actions. Energy vulnerability measurement and modelling should ultimately inform policy. In particular, member states should legislate that no energy infrastructure project by one or more member states may increase the energy vulnerability of another member state. Additionally, European environmental policies, notably the EU ETS, should be amended so as to account for induced changes in energy vulnerability. Finally, member states should increase the level of transparency and disclosure with respect to gas import statistics and gas supply contracts.

Considerations on the Marketing Plan for Brazilian Micro Enterprises

Directory of Open Access Journals (Sweden)

Edmir Kuazaqui

2015-06-01

Full Text Available This article aims to present the main marketing concepts applied by micro-enterprises within a brief contextualization of a marketing plan. The development and theoretical evolution have stemmed from the bibliographical research as well as field research and observational studies by the author of the article. The goal is neither to exhaust the topic or to construct a Marketing Plan, but rather to contribute to the discussion, learning and use of a marketing mix in the segment of micro-enterprises in a more assertive manner. It was concluded that there is no doubt as to the importance of micro-enterprises for any country. Their contribution lies mainly in the economic and social insertion. It should be taken into account that micro-enterprises are greatly responsible for job generation in our country, realising their prominent social and ecological perspective. More than a transient way of earning money, the reality of micro-enterprises must be considered as a social and economic phenomenon capable of generating regional and consequently, global growth.

Uncertainty in relative energy resolution measurements

International Nuclear Information System (INIS)

Volkovitsky, P.; Yen, J.; Cumberland, L.

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

Relating Financial and Energy Return on Investment

Directory of Open Access Journals (Sweden)

Carey W. King

2011-10-01

Full Text Available For many reasons, including environmental impacts and the peaking and depletion of the highest grades of fossil energy, it is very important to have sound methods for the evaluation of energy technologies and the profitability of the businesses that utilize them. In this paper we derive relations among the biophysical characteristic of an energy resource in relation to the businesses and technologies that exploit them. These relations include the energy return on energy investment (EROI, the price of energy, and the profit of an energy business. Our analyses show that EROI and the price of energy are inherently inversely related such that as EROI decreases for depleting fossil fuel production, the corresponding energy prices increase dramatically. Using energy and financial data for the oil and gas production sector, we demonstrate that the equations sufficiently describe the fundamental trends between profit, price, and EROI. For example, in 2002 an EROI of 11:1 for US oil and gas translates to an oil price of 24 $2005/barrel at a typical profit of 10%. This work sets the stage for proper EROI and price comparisons of individual fossil and renewable energy businesses as well as the electricity sector as a whole. Additionally, it presents a framework for incorporating EROI into larger economic systems models.

Energy and Uncertainty in General Relativity

Science.gov (United States)

Cooperstock, F. I.; Dupre, M. J.

2018-03-01

The issue of energy and its potential localizability in general relativity has challenged physicists for more than a century. Many non-invariant measures were proposed over the years but an invariant measure was never found. We discovered the invariant localized energy measure by expanding the domain of investigation from space to spacetime. We note from relativity that the finiteness of the velocity of propagation of interactions necessarily induces indefiniteness in measurements. This is because the elements of actual physical systems being measured as well as their detectors are characterized by entire four-velocity fields, which necessarily leads to information from a measured system being processed by the detector in a spread of time. General relativity adds additional indefiniteness because of the variation in proper time between elements. The uncertainty is encapsulated in a generalized uncertainty principle, in parallel with that of Heisenberg, which incorporates the localized contribution of gravity to energy. This naturally leads to a generalized uncertainty principle for momentum as well. These generalized forms and the gravitational contribution to localized energy would be expected to be of particular importance in the regimes of ultra-strong gravitational fields. We contrast our invariant spacetime energy measure with the standard 3-space energy measure which is familiar from special relativity, appreciating why general relativity demands a measure in spacetime as opposed to 3-space. We illustrate the misconceptions by certain authors of our approach.

Energy problem and harmony in international relations

Energy problems and harmony in international relation are closely related with world politics. Oil is destined to remain as the primary energy source for the time being. The situation of oil has different implications to the U.S. and U.S.S.R., oil producing countries, and consumer countries. The hasty attitude in the past to attain energy sufficiency must be avoided by all means. Congenial harmony is to be established in international relation to meet world energy requirement. This also applies to the case of nuclear power in future. (Mori, K.)

Relative energy for the Korteweg theory and related Hamiltonian flows in gas dynamics

KAUST Repository

Giesselmann, Jan

2016-10-26

For an Euler system, with dynamics generated by a potential energy functional, we propose a functional format for the relative energy and derive a relative energy identity. The latter, when applied to specific energies, yields relative energy identities for the Euler-Korteweg, the Euler-Poisson, the Quantum Hydrodynamics system, and low order approximations of the Euler-Korteweg system. For the Euler-Korteweg system we prove a stability theorem between a weak and a strong solution and an associated weak-strong uniqueness theorem. In the second part we focus on the Navier-Stokes-Korteweg system (NSK) with non-monotone pressure laws: we prove stability for the NSK system via a modified relative energy approach. We prove continuous dependence of solutions on initial data and convergence of solutions of a low order model to solutions of the NSK system. The last two results provide physically meaningful examples of how higher order regularization terms enable the use of the relative energy framework for models with energies which are not poly- or quasi-convex, but compensating via higher-order gradients.

The Opacity of Russian-Ukrainian Energy Relations

Energy issues lie at the heart of Ukraine's economic, political and strategic challenges. A year after the 'orange revolution', the 'gas war' served to highlight the country's vulnerable position, being 80% dependent on imports of gas and having the world's most energy hungry economy. The 2005 crisis also highlighted the extreme opacity of the country's bilateral relations with Russia, which are governed as much by the interests surrounding Gazprom's relations as by those of the state. Yanukovich's return to power in the summer of 2006 coincided with a relative appeasement of relations with Moscow and a new division of spheres of influence in the Ukrainian energy sector. (author)

PROFIT TAX OR INCOME TAX? OPTIONS FOR FISCAL OPTIMIZATION OF ROMANIAN SMALL COMPANIES

Directory of Open Access Journals (Sweden)

Doina Pacurari

2013-12-01

Full Text Available Entrepreneurs usually seek for solutions to reduce their tax burden. We can speak about tax optimization as long as these solutions are in accordance with the law; if they are not, they obviously fall into the area of fiscal fraud. This paper addresses the issue of taxation applicable to the Romanian micro-enterprises. These are small entities that fulfil certain conditions regarding total turnover, equity and domain of activity. Although the provisions applying to micro-enterprise taxation were elaborated, among others, with the intention to reduce tax evasion, they also allow the micro-enterprises with losses to avoid tax payment. In a country with low purchasing power and a great number of taxes and fees like Romania, the entrepreneurs are tempted to use any kind of method to reduce the payments due to the state budget. The micro-enterprise owners make no exception in this matter.

Asymmetric interdependence in the Czech–Russian energy relations

International Nuclear Information System (INIS)

Binhack, Petr; Tichý, Lukáš

2012-01-01

This paper addresses the issue of asymmetric energy relations between the Czech Republic and the Russian Federation. The theory of interdependence is a widely used concept in political and economic studies of international relations. As can be seen from the analysis of Czech–Russian energy relations and its costs and benefits, the interdependence cannot be limited to a situation of equal interdependence. Energy sensitivity and vulnerability of the Czech Republic towards Russia is considered as a key source of power for the energy policy of Russia vis-à-vis the Czech Republic. The evidence for this claim can be found in the procedures and expressions of Russia’s energy policy. On the other hand, the energy policy of the Czech Republic is influenced by the European Union and its focus on the liberalization of the energy market, diversification of the currently existing transportation routes and legislative proposals aimed at strengthening the EU’s own energy security. The European Union significantly contributes to an increase of the energy security of the Czech Republic. The European Union and regional cooperation (such as the V4 group) could balance out the asymmetry of interdependence, thus lowering the sensitivity and vulnerability of the Czech Republic towards Russia. - Highlights: ► We examine energy relations between the Czech Republic and the Russian Federation. ► We use the concept of asymmetric interdependence in energy relations. ► Energy sensitivity and vulnerability of the Czech Republic are key variables. ► The asymmetric interdependence is a source of power for Russian energy policy. ► The EU and V4 cooperation contribute to an energy security of the Czech Republic.

Who puts the most energy into energy conservation? A segmentation of energy consumers based on energy-related behavioral characteristics

Sütterlin, Bernadette; Brunner, Thomas A.; Siegrist, Michael

2011-01-01

The present paper aims to identify and describe different types of energy consumers in a more comprehensive way than previous segmentation studies using cluster analysis. Energy consumers were segmented based on their energy-related behavioral characteristics. In addition to purchase- and curtailment-related energy-saving behavior, consumer classification was also based on acceptance of policy measures and energy-related psychosocial factors, so the used behavioral segmentation base was more comprehensive compared to other studies. Furthermore, differentiation between the energy-saving purchase of daily products, such as food, and of energy efficient appliances allowed a more differentiated characterization of the energy consumer segments. The cluster analysis revealed six energy consumer segments: the idealistic, the selfless inconsequent, the thrifty, the materialistic, the convenience-oriented indifferent, and the problem-aware well-being-oriented energy consumer. Findings emphasize that using a broader and more distinct behavioral base is crucial for an adequate and differentiated description of energy consumer types. The paper concludes by highlighting the most promising energy consumer segments and discussing possible segment-specific marketing and policy strategies. - Highlights: ► By applying a cluster-analytic approach, new energy consumer segments are identified. ► A comprehensive, differentiated description of the different energy consumer types is provided. ► A distinction between purchase of daily products and energy efficient appliances is essential. ► Behavioral variables are a more suitable base for segmentation than general characteristics.

2013-06-01

Full Text Available This article discusses European Union (EU-North Africa energy relations with a special focus on renewables in North Africa, arguing that the research so far has not taken due account of North African perceptions of EU external energy policy. It is argued that current research on EU-North African relations has not taken sufficient note of the multidimensionality of energy or addressed the inconsistent nature of EU policy making. However, addressing these issues is vital in approaching EU-North Africa energy relations and EU policy towards North Africa in general. The study of perceptions is introduced as one way to develop research further, to give further impetus on understanding how EU-North African energy relations develop and to understand energy relations in their complexity.

Evaluation of energy related risk acceptance (APHA energy task force)

International Nuclear Information System (INIS)

Hull, A.P.

1977-01-01

Living in a technological society with large energy requirements involves a number of related actities with attendant health risks, both to the working and to the general public. Therefore, the formulation of some general principles for risk acceptance is necessary. In addition to maximizing benefits and minimizing risk, relevant considerations must be made about the perception of risk as voluntary or involuntary, the number of persons collectively at risk at any one occasion, and the extent to which a risk is a familiar one. With regard to a given benefit, such as a given amount of energy, comparisons of the risks of alternate modes of production may be utilized. However, cost-benefit consideration is essential to the amelioration of current or prospective risks. This is unusual, since it is based on some estimate of the monetary value per premature death averted. It is proposed that increased longevity would be a more satisfactory measure. On a societal basis, large expenditures for additional energy-related pollution control do not appear justifiable since much larger, nonenergy-related health risks are relatively underaddressed. Knowledgeable health professionals could benefit the public by imparting authoritative information in this area

The dominant energy condition in general relativity theory, which says that every observer measures a nonnegative local energy density and a nonspacelike local energy flow, is examined in connection with the types of energy-momentum tensor it permits. The condition that the energy-momentum tensor be ''stable'' in obeying the dominant energy conditions is then defined in terms of a suitable topology on the set of energy-momentum tensors on space-time and the consequences are evaluated and discussed.

The aim of this article is to explore this dynamic interdependent relationship between Russia and Europe in the field of energy. Based on the concept of interdependence and perspectives on the political aspects of trade relations we discuss how Russia can exercise power based on its energy resources and how the EU can compensate for its lack of power in the energy game with other trade related capabilities. In particular we explore the implications of the lack of a full-fledged EU foreign energy policy towards Russia, with the somewhat counter-intuitive conclusion that the EU countries, on average, not necessarily are better off with a common foreign energy policy. - Highlights: • We examine Russian–European gas (inter)dependence. • East-European countries are most dependent on Russian gas in Europe. • EU countries, on average, are not better off with a common foreign energy policy

Are energy-dense foods really cheaper? Reexamining the relation between food price and energy density.

Lipsky, Leah M

2009-11-01

The inverse relation between energy density (kcal/g) and energy cost (price/kcal) has been interpreted to suggest that produce (fruit, vegetables) is more expensive than snacks (cookies, chips). The objective of this study was to show the methodologic weakness of comparing energy density with energy cost. The relation between energy density and energy cost was replicated in a random-number data set. Additionally, observational data were collected for produce and snacks from an online supermarket. Variables included total energy (kcal), total weight (g), total number of servings, serving size (g/serving), and energy density (kcal/g). Price measures included energy cost ($/kcal), total price ($), unit price ($/g), and serving price ($/serving). Two-tailed t tests were used to compare price measures by food category. Relations between energy density and price measures within food categories were examined with the use of Spearman rank correlation analysis. The relation between energy density and energy cost was shown to be driven by the algebraic properties of these variables. Food category was strongly correlated with both energy density and food price measures. Energy cost was higher for produce than for snacks. However, total price and unit price were lower for produce. Serving price and serving size were greater for produce than for snacks. Within food categories, energy density was uncorrelated with most measures of food price, except for a weak positive correlation with serving price within the produce category. The findings suggest the relation between energy density and food price is confounded by food category and depends on which measure of price is used.

Reconsidering relations between nuclear energy and security concepts

International Nuclear Information System (INIS)

Irie, Kazutomo

2004-01-01

Relations between nuclear energy and security concepts can be clarified through investigation into the multivocal nature of security concepts. While military uses of nuclear energy significantly influence national security, peaceful uses of nuclear energy contribute energy security, which is an expanded concept of national security. Military and peaceful uses of nuclear energy have reciprocal actions, thus influencing national security and energy security, respectively. Nuclear security, which means security of nuclear systems themselves, recently attracts the attention of the international society. Nuclear security directly influences national security issues. On the other hand, along with nuclear safety, nuclear security becomes a prerequisite for energy security through peaceful uses of nuclear energy. In investigating into relations between nuclear energy and security concepts, the difficulty of translating the English word of 'nuclear security' into Japanese as well as other languages is found.

Energy is emerging as a topic of importance to organizations, yet we have little understanding of how energy can be useful at an interpersonal level toward achieving workplace goals. We present the results of 4 studies aimed at developing, validating, and testing the relational energy construct. In Study 1, we report qualitative insights from 64 individuals about the experience and functioning of relational energy in the workplace. Study 2 draws from 3 employee samples to conduct exploratory and confirmatory factor analyses on a measure of relational energy, differentiating relational energy from related constructs. To test the predictive validity of the new relational energy scale, Study 3 comprises data from employees rating the level of relational energy they experienced during interactions with their leaders in a health services context. Results showed that relational energy employees experienced with their leaders at Time 1 predicted job engagement at Time 2 (1 month later), while controlling for the competing construct of perceived social support. Study 4 shows further differentiation of relational energy from leader-member exchange (LMX), replicates the positive relationship between relational energy (Time 1) and job engagement (Time 2), and shows that relational energy is positively associated with employee job performance (Time 3) through the mechanism of job engagement. We discuss the theoretical implications of our findings and highlight areas for future research. (c) 2016 APA, all rights reserved).

Advertising, marketing and purchase behavior for energy-related products

Tiedemann, K.; Nelson, D.

Energy conservation programs have relied heavily on incentives and regulatory standards to reduce residential energy consumption. However, in the changing market environment characterized by competitive pressures, alternative mechanisms such as marketing and promotions may increase substantially in importance compared to the demand-side management programs which have been the focus of most research. This paper describes the role of marketing and promotions in encouraging energy efficiency at the household level in British Columbia. The paper examines three related issues: first, the purchase process for energy-related products; second, the criteria used by customers in making purchase decisions; and third, the impact and effectiveness of alternative marketing tools. A key finding is the energy-related purchases do not fall into the impulse purchase category. There are two reasons for this: first, most of these products require installation and this requires a high level of commitment on the part of the purchaser; second, many energy-related products require a significant outlay of funds and this reduces impulse buying.

Ata, Engin; Demirhan, Doğan; Büyükkılıç, Fevzi

2017-04-01

An exactly solvable relativistic approach based on inseparable periodic well potentials is developed to obtain energy-dispersion relations of spin states of a single-electron in two-dimensional (2D) rectangular lattices. Commutation of axes transfer matrices is exploited to find energy dependencies of the wave vector components. From the trace of the lattice transfer matrix, energy-dispersion relations of conductance and valence states are obtained in transcendental form. Graphical solutions of relativistic and nonrelativistic transcendental energy-dispersion relations are plotted to compare how lattice parameters V0, core and interstitial size of the rectangular lattice affects to the energy-band structures in a situation core and interstitial diagonals are of equal slope.

Microcredit -- an emerging tool for fighting poverty.

Science.gov (United States)

1997-01-01

A summit focusing on microcredit (small business, microenterprise, loans) as a means of fighting poverty was held February 3-4 in Washington; it was co-chaired by First Lady Hillary Rodham Clinton and by Queen Sofia of Spain. The United States Agency for International Development (USAID) has long supported microenterprise and microfinance. The summit set a goal of reaching 100 million poor families over the next nine years. USAID Administrator Brian Atwood spoke concerning the need to involve the private sector in microfinance; previously loans had been financed outside of the mainstream financial system via nongovernmental organizations and credit unions funded mainly by governments and donors. USAID launched a Microenterprise Initiative in 1994 that has supported 150 programs in 45 countries, and that is expected to reach approximately 4 million families. Atwood said the microenterprise strategies were currently in use in nearly every country USAID supports in Latin America and Asia, and most countries in Africa; future efforts would concentrate on countries in Africa, in eastern Europe and in central Asia. Mrs. Clinton called microenterprise "an invaluable tool in alleviating poverty, promoting self-sufficiency, and stimulating the economy." Treasury Secretary Robert Rubin stated that the policy helped people help themselves by giving them the tools they needed to join the economic mainstream. Microcredit focuses on businesses with five or fewer workers; loans range from less than $100 to $10,000. More than half of the businesses are owned and operated by women.

A successful energy transition will depend not only on the development of new energy technologies, but also on changes in the patterns of individual energy-related decisions and behaviors resulting in substantial reductions in energy demand. Across scientific disciplines, most theoretical approaches that try to understand energy-related decisions and behaviors focus mainly on cognitive processes, such as computations of utility (typically economic), the impact of cognitive heuristics, or the role of individual beliefs. While these models already explain important aspects of human decisions and behavior in the energy domain, we argue that an additional consideration of the contributions of emotional processes may be very fruitful for a deeper understanding of the issue. In this contribution, we outline a theoretical perspective on energy-related decisions and behaviors that integrates emotions, elicited by a cognitive-affective appraisal of the relevance of a situation, into a response system driving adaptive decisions and behaviors. We empirically investigate the explanatory power of the model variables to predict intentions to reduce energy use demonstrating that the appraisal–emotion variables are able to account for additional variance that is not explained by two established models focused on cognitive processes (theory of planned behavior and value-belief-norm theory). Finally, we discuss how the appraisal–emotion approach may be fruitfully integrated with other existing approaches and outline some questions for future research.

2017-01-01

Energy drink consumption, with or without concurrent alcohol use, is common among young adults. This study sought to clarify risk for negative alcohol outcomes related to the timing of energy drink use. The authors interviewed a community sample of 481 young adults, aged 18-25, who drank alcohol in the last month. Past-30-day energy drink use was operationalized as no-use, use without concurrent alcohol, and concurrent use of energy drinks with alcohol ("within a couple of hours"). Negative alcohol outcomes included past-30-day binge drinking, past-30-day alcohol use disorder, and drinking-related consequences. Just over half (50.5%) reported no use of energy drinks,18.3% reported using energy drinks without concurrent alcohol use, and 31.2% reported concurrent use of energy drinks and alcohol. Relative to those who reported concurrent use of energy drinks with alcohol, and controlling for background characteristics and frequency of alcohol consumption, those who didn't use energy drinks and those who used without concurrent alcohol use had significantly lower binge drinking, negative consequences, and rates of alcohol use disorder (P energy drink without concurrent alcohol groups on any alcohol-related measure (P > .10 for all outcomes). Concurrent energy drink and alcohol use is associated with increased risk for negative alcohol consequences in young adults. Clinicians providing care to young adults could consider asking patients about concurrent energy drink and alcohol use as a way to begin a conversation about risky alcohol consumption while addressing 2 substances commonly used by this population.

Energy-range relations for hadrons in nuclear matter

Strugalski, Z.

1985-01-01

Range-energy relations for hadrons in nuclear matter exist similarly to the range-energy relations for charged particles in materials. When hadrons of GeV kinetic energies collide with atomic nuclei massive enough, events occur in which incident hadron is stopped completely inside the target nucleus without causing particle production - without pion production in particular. The stoppings are always accompanied by intensive emission of nucleons with kinetic energy from about 20 up to about 400 MeV. It was shown experimentally that the mean number of the emitted nucleons is a measure of the mean path in nuclear matter in nucleons on which the incident hadrons are stopped.

A lot of efforts are directed now to study the interactions between energy and climate because of their significant importance for our planet. Globally, energy related emissions of Greenhouse Gases (GHGs) contribute for atmospheric warming. On regional level, where it is more difficult to determine concrete direction of climate variability and change, the role of energy remains considerable being not so direct as in the case of emissions` impact. Still there is essential necessity for further analyses and assessments of energy related climate variations and change in order to understand better and to quantify the energy - climate relations. In the presentation an attempt is made to develop approach for assessment of energy related climate variations on regional level. For this purpose, data and results from the research within Bulgarian Case Study (BCS) in the DECADES Inter-Agency Project framework are used. Considering the complex nature of the examined interconnections and the medium stage of the Study`s realisation, at the moment the approach can be presented in conceptual form. Correspondingly, the obtained results are illustrative and preliminary

Deriving mass-energy equivalence and mass-velocity relation without light

Science.gov (United States)

Dai, Youshan; Dai, Liang

2018-04-01

Relativity requires that a particle's momentum and energy are the same functions of the particle's velocity in all inertial frames. Using the fact that momentum and energy must transform linearly between reference frames, we present a novel derivation of the mass-energy equivalence, namely, the relation that the energy is proportional to the moving mass, with no postulate about the existence of light or its properties. We further prove the mass-velocity relation without relying on momentum and energy conservation or on the Lorentz transformation. It is demonstrated that neither conservation laws nor the Lorentz transformation are necessary to establish those relations, and that those relations have a wider scope of validity than that of the conservation laws and the invariance of the speed of light.

Gamma-ray relative energy response of Ce: YAG crystal, which is important for pulsed γ-ray measurement, was studied in this work.The Ce: YAG crystal, which was developed at Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, was aligned point by point with γ-rays scattered from an industrial 60 Co line source. The γ-ray relative energy response was calculated using the mass attenuation coefficient. The results show that the numerical calculation method of γ-ray relative energy response is reliable, and the experimental method with multi-energy point γ-ray by Compton scattering is also feasible, that can be used for checking up correctness of the numerical calculation results.

For a particular community, what energy-related innovations constitute no-regrets strategies? We present a methodology to understand how alternative energy consuming activities and policy regimes impact on current and future liveability of socio-culturally diverse communities facing climate change. Our methodology augments the energy policy literature by harnessing three concepts (collaborative governance, innovation and political economic regime of provisioning) to support dialogue around changing energy-related activities. We convened workshops in Alice Springs, Australia to build capability to identify no-regrets energy-related housing or transport activities and strategies. In preparation, we interviewed policy actors and constructed three new housing-related future scenarios. After discussing the scenarios, policy and research actors prioritised five socio-technical activities or strategies. Evaluations indicate participants enjoyed opportunities given by the methodology to have focussed discussions about activities and innovation, while requesting more socially nuanced scenario storylines. We discuss implications for theory and technique development. - Highlights: •Energy-related activities and regimes frustrate pro-sustainability action. •Participatory workshops increased understanding of activities and regimes. •Workshops used a novel combination of governance and social theories. •Results justify inclusive dialogue around building energy standards and transport options.

Relation of wave energy and momentum with the plasma dispersion relation in an inhomogeneous plasma

International Nuclear Information System (INIS)

Berk, H.L.; Pfirsch, D.

1988-01-01

The expressions for wave energy and angular momentum commonly used in homogeneous and near-homogeneous media is generalized to inhomogeneous media governed by a nonlocal conductivity tensor. The expression for wave energy applies to linear excitations in an arbitrary three-dimensional equilibrium, while the expression for angular momentum applies to linear excitations of azimuthally symmetric equilibria. The wave energy E-script/sub wave/ is interpreted as the energy transferred from linear external sources to the plasma if there is no dissipation. With dissipation, such a simple interpretation is lacking as energy is also thermally absorbed. However, for azimuthally symmetric equilibria, the expression for the wave energy in a frame rotating with a frequency ω can be unambiguously separated from thermal energy. This expression is given by E-script/sub wave/ -ωL/sub wave/ l, where L/sub wave/ is the wave angular momentum defined in the text and l the azimuthal wavenumber and it is closely related to the real part of a dispersion relation for marginal stability. The imaginary part of the dispersion is closely related to the energy input into a system. Another useful quantity discussed is the impedance form, which can be used for three-dimensional equilibrium without an ignorable coordinate and the expression is closely related to the wave impedance used in antenna theory. Applications to stability theory are also discussed

Acceptance of energy-related technologies by end residential consumers, manufacturers of energy-related products, and other influential intermediate markets such as builders will influence the potential for market penetration of innovative energy-related technologies developed by the Department of Energy, Office of Building and Community Systems (OBCS). In this report, Pacific Northwest Laboratory reviewed the available information on technology adoption, diffusion, and decision-making processes to provide OBCS with a background and understanding of the type of research that has previously been conducted on this topic. Insight was gained as to the potential decision-making criteria and motivating factors that influence the decision-maker(s) selection of new technologies, and some of the barriers to technology adoption faced by potential markets for OBCS technologies.

Brown, Matthew, H; Decesaro, Jennifer; DOE Project Officer - Keith Bennett

2005-07-15

This final report summarizes work carried out under agreement with the US Department of Energy, related to wind energy policy issues. This project has involved a combination of outreach and publications on wind energy, with a specific focus on educating state-level policymakers. Education of state policymakers is vitally important because state policy (in the form of incentives or regulation) is a crucial part of the success of wind energy. State policymakers wield a significant influence over all of these policies. They are also in need of high quality, non-biased educational resources which this project provided. This project provided outreach to legislatures, in the form of meetings designed specifically for state legislators and legislative staff, responses to information requests on wind energy, and publications. The publications addressed: renewable energy portfolio standards, wind energy transmission, wind energy siting, case studies of wind energy policy, avian issues, economic development, and other related issues. These publications were distributed to legislative energy committee members, and chairs, legislative staff, legislative libraries, and other related state officials. The effect of this effort has been to provide an extensive resource of information about wind information for state policymakers in a form that is useful to them. This non-partisan information has been used as state policymakers attempt to develop their own policy proposals related to wind energy in the states.

Some problems of solar-terrestrial energy relations

Kovalevskij, I.V.

1982-01-01

Energy aspects of relations of phenomena occurring on the Sun, in the interplanetary space, magnetosphere, ionosphere and on the Earth's surface are discussed. Particular attention is given to the energy radiated by the Sun (flares, coronal holes). The problems are considered of the energy transfer and transformation in high-velocity and flare flows of solar wind. Estimates are performed: of densities of various types of energy of the interplanetary space at the Earth's orbit level; energy fluxes incident on the magnetosphere; energy accumulated inside the magnetosphere; a series of energy parameters of magnetic storms. It is pointed out that nowadays one of the main problems of the magnetosphere physics is studying ways of the interplanatary space energy transfer into the magnetosphere. In this connection some problems are investigated: plasma penetration through the dayside magnetopause, solar wind plasma entry into the magnetotail, the electric field effect on transition region plasma penetration into the distant magnetotail

Prediction of energy-related technology for next 30 years

1987-12-01

The report outlines major results of a survey concerning technologies expected to emerge during the next 30 years that was carried out by the Japan's Science and Technology Agency using the DELPHI method. The survey covered 51 technical issues in energy-related areas including fossil energy, nucler energy, natural energy, biomass and energy utilization techniques, and process-related areas including exploration, collection/extraction, transportation/storage, power generation, resources conversion and substitution. For each technical issue, investigation is made on its importance, time of realization, restrictions, procedure and responsible organization for promoting research and development, and government policy. Results show that the importance of nuclear energy will continue to increase and that diversification of energy sources, such as shift to coal, will also become more important. It is indicated that technological breakthroughs, such as the development of new superconducting materials, will accelerate the development of other techniques in related areas and simultaneously increase the importance of such techniques. The survey provides valuable basic data serving for predicting future social changes that may be caused by technical innovation or a shift in view on technology in the economic areas or in the society.

Fisher information, kinetic energy and uncertainty relation inequalities

International Nuclear Information System (INIS)

Luo Shunlong

2002-01-01

By interpolating between Fisher information and mechanical kinetic energy, we introduce a general notion of kinetic energy with respect to a parameter of Schroedinger wavefunctions from a statistical inference perspective. Kinetic energy is the sum of Fisher information and an integral of a parametrized analogue of quantum mechanical current density related to phase. A family of integral inequalities concerning kinetic energy and moments are established, among which the Cramer-Rao inequality and the Weyl-Heisenberg inequality, are special cases. In particular, the integral inequalities involving the negative order moments are relevant to the study of electron systems. Moreover, by specifying the parameter to a scale, we obtain a family of inequalities of uncertainty relation type which incorporate the position and momentum observables symmetrically in a single quantity.

[Decomposition model of energy-related carbon emissions in tertiary industry for China].

Science.gov (United States)

Lu, Yuan-Qing; Shi, Jun

2012-07-01

Tertiary industry has been developed in recent years. And it is very important to find the factors influenced the energy-related carbon emissions in tertiary industry. A decomposition model of energy-related carbon emissions for China is set up by adopting logarithmic mean weight Divisia method based on the identity of carbon emissions. The model is adopted to analyze the influence of energy structure, energy efficiency, tertiary industry structure and economic output to energy-related carbon emissions in China from 2000 to 2009. Results show that the contribution rate of economic output and energy structure to energy-related carbon emissions increases year by year. Either is the contribution rate of energy efficiency or the tertiary industry restraining to energy-related carbon emissions. However, the restrain effect is weakening.

The impact of relative energy prices on industrial energy consumption in China: a consideration of inflation costs.

Science.gov (United States)

He, Lingyun; Ding, Zhihua; Yin, Fang; Wu, Meng

2016-01-01

Significant effort has been exerted on the study of economic variables such as absolute energy prices to understand energy consumption and economic growth. However, this approach ignores general inflation effects, whereby the prices of baskets of goods may rise or fall at different rates from those of energy prices. Thus, it may be the relative energy price, not the absolute energy price, that has most important effects on energy consumption. To test this hypothesis, we introduce a new explanatory variable, the domestic relative energy price, which we define as "the ratio of domestic energy prices to the general price level of an economy," and we test the explanatory power of this new variable. Thus, this paper explores the relationship between relative energy prices and energy consumption in China from the perspective of inflation costs over the period from 1988 to 2012. The direct, regulatory and time-varying effects are captured using methods such as ridge regression and the state-space model. The direct impacts of relative energy prices on total energy consumption and intensity are -0.337 and -0.250, respectively; the effects of comprehensive regulation on energy consumption through the economic structure and the energy structure are -0.144 and -0.148, respectively; and the depressing and upward effects of rising and falling energy prices on energy consumption are 0.3520 and 0.3564, respectively. When economic growth and the energy price level were stable, inflation persisted; thus, rising energy prices benefitted both the economy and the environment. Our analysis is important for policy makers to establish effective energy-pricing policies that ensure both energy conservation and the stability of the pricing system.

A new instrument for measuring housing-related lifestyle (HRL) is introduced and employed for identifying national and cross-national HRL segments in 10 European countries (N=3190). The identified HRL segments are profiled and the practical importance of HRL for everyday energy-saving efforts in the home and for the energy-consumer's openness to new energy saving opportunities (i.e., energy saving innovativeness) is investigated. The HRL instrument's 71 items load on 16 dimensions within five lifestyle elements. Multi-group confirmatory factor analysis reveals that the instrument possesses metric but not scalar (measurement) invariance across the 10 countries. Multilevel latent class analysis is used to classify participants to HRL segments and the 10 countries into regions with similar segment structure. The optimal solution has seven HRL segments and three country classes, which are profiled in terms of relevant background characteristics. A multivariate GLM analysis reveals that when differences in housing-related lifestyles are controlled, neither country of residence nor the interaction between lifestyle and country of residence influence energy saving innovativeness or everyday energy-saving efforts. However, these two behavioural tendencies vary significantly and substantially between lifestyle segments. The study shows that HRL segmentation is a useful tool for creating more targeted and effective energy-saving campaigns. - Highlights: • 7 housing-related lifestyle segments identified in 10 European countries. • The 10 countries cluster in 3 regions with similar housing-related lifestyle pattern. • Lifestyle segments differ significantly with regard to energy saving efforts. • Lifestyle segments also differ with regard to energy saving innovativeness. • Housing-related lifestyle mediate all effects of country on energy saving.

Exact relations for energy transfer in self-gravitating isothermal turbulence.

Banerjee, Supratik; Kritsuk, Alexei G

2017-11-01

Self-gravitating isothermal supersonic turbulence is analyzed in the asymptotic limit of large Reynolds numbers. Based on the inviscid invariance of total energy, an exact relation is derived for homogeneous (not necessarily isotropic) turbulence. A modified definition for the two-point energy correlation functions is used to comply with the requirement of detailed energy equipartition in the acoustic limit. In contrast to the previous relations (S. Galtier and S. Banerjee, Phys. Rev. Lett. 107, 134501 (2011)PRLTAO0031-900710.1103/PhysRevLett.107.134501; S. Banerjee and S. Galtier, Phys. Rev. E 87, 013019 (2013)PLEEE81539-375510.1103/PhysRevE.87.013019), the current exact relation shows that the pressure dilatation terms play practically no role in the energy cascade. Both the flux and source terms are written in terms of two-point differences. Sources enter the relation in a form of mixed second-order structure functions. Unlike the kinetic and thermodynamic potential energies, the gravitational contribution is absent from the flux term. An estimate shows that, for the isotropic case, the correlation between density and gravitational acceleration may play an important role in modifying the energy transfer in self-gravitating turbulence. The exact relation is also written in an alternative form in terms of two-point correlation functions, which is then used to describe scale-by-scale energy budget in spectral space.

Constraints on stress-energy perturbations in general relativity

International Nuclear Information System (INIS)

Traschen, J.

1985-01-01

Conditions are found for the existence of integral constraints on stress-energy perturbations in general relativity. The integral constraints can be thought of as a general-relativistic generalization of the conservation of energy and momentum of matter perturbations in special relativity. The constraints are stated in terms of a vector field V, and the Robertson-Walker spacetimes are shown to have such constraint vectors. Although in general V is not a Killing vector, in a vacuum spacetime the constraint vectors are precisely the Killing vectors

Yu, Le; Hu, Han; Wu, Hao Bin; Lou, Xiong Wen David

2017-04-01

Hollow nanostructures offer promising potential for advanced energy storage and conversion applications. In the past decade, considerable research efforts have been devoted to the design and synthesis of hollow nanostructures with high complexity by manipulating their geometric morphology, chemical composition, and building block and interior architecture to boost their electrochemical performance, fulfilling the increasing global demand for renewable and sustainable energy sources. In this Review, we present a comprehensive overview of the synthesis and energy-related applications of complex hollow nanostructures. After a brief classification, the design and synthesis of complex hollow nanostructures are described in detail, which include hierarchical hollow spheres, hierarchical tubular structures, hollow polyhedra, and multi-shelled hollow structures, as well as their hybrids with nanocarbon materials. Thereafter, we discuss their niche applications as electrode materials for lithium-ion batteries and hybrid supercapacitors, sulfur hosts for lithium-sulfur batteries, and electrocatalysts for oxygen- and hydrogen-involving energy conversion reactions. The potential superiorities of complex hollow nanostructures for these applications are particularly highlighted. Finally, we conclude this Review with urgent challenges and further research directions of complex hollow nanostructures for energy-related applications. © 2017 WILEY-VCH Verlag GmbH & Co.

The Karolyhazy uncertainty relation indicates that there exists a minimal detectable cell {delta}t{sup 3} over the region t{sup 3} in Minkowski space-time. Due to the energy-time uncertainty relation, the energy of the cell {delta}t {sup 3} cannot be less {delta}t{sup -1}. Then we get a new energy density of metric fluctuations of Minkowski spacetime as {delta}t{sup -4}. Motivated by the energy density, we propose two new dark-energy models. One model is characterized by the age of the universe and the other is characterized by the conformal age of the universe. We find that in the two models, the dark energy mimics a cosmological constant in the late time. (orig.)

Renewable Energy and Proven Oil Reserves Relation: Evidence from OPEC Members

Directory of Open Access Journals (Sweden)

Mehmet Arcan TUZCU

2014-12-01

Full Text Available The well documented literature on the relation between energy consumption and climate change has been extended by the addition of renewable energy consumption. Several studies show its impact on technical efficiency, per capita income or carbon dioxide (CO2 emission levels for developed and developing countries. However, to the extent of our knowledge, very few of them state the importance of renewable energy for the countries where the main type of fossil fuels, oil, is exported. This study aims to explore the association between renewable energy, real gross domestic product (GDP, CO2 emission level, real oil prices as well as the proven oil reserves for seven members of Organization of the Petroleum Exporting Countries (OPEC. The analyses are conducted using panel data techniques, namely fixed effect – random effect tests. Our results show a positive and significant relation between renewable energy consumption, and real GDP and CO2 emission level. A statistically not significant coefficient is found for the relation between renewable energy and the proven oil reserves. The relation between energy and real oil prices is also insignificant.

A fluctuation relation for the probability of energy backscatter

Science.gov (United States)

Vela-Martin, Alberto; Jimenez, Javier

2017-11-01

We simulate the large scales of an inviscid turbulent flow in a triply periodic box using a dynamic Smagorinsky model for the sub-grid stresses. The flow, which is forced to constant kinetic energy, is fully reversible and can develop a sustained inverse energy cascade. However, due to the large number of degrees freedom, the probability of spontaneous mean inverse energy flux is negligible. In order to quantify the probability of inverse energy cascades, we test a local fluctuation relation of the form log P(A) = - c(V , t) A , where P(A) = p(| Cs|V,t = A) / p(| Cs|V , t = - A) , p is probability, and | Cs|V,t is the average of the least-squared dynamic model coefficient over volume V and time t. This is confirmed when Cs is averaged over sufficiently large domains and long times, and c is found to depend linearly on V and t. In the limit in which V 1 / 3 is of the order of the integral scale and t is of the order of the eddy-turnover time, we recover a global fluctuation relation that predicts a negligible probability of a sustained inverse energy cascade. For smaller V and t, the local fluctuation relation provides useful predictions on the occurrence of local energy backscatter. Funded by the ERC COTURB project.

Science.gov (United States)

Misnon, Fauzan Amin; Hu, Yeoh Siong; Rahman, Irman Abd.; Yasir, Muhamad Samudi

2017-01-01

Malaysia had considered nuclear energy as an option for future electricity generation during the 9th Malaysia Development Plan. Since 2009, Malaysia had implemented a number of important preparatory steps towards this goal, including the establishment of Nuclear Power Corporation of Malaysia (MNPC) as first Nuclear Energy Programme Implementing Organization (NEPIO) in Malaysia. In light of the establishment of MNPC, the National Nuclear Policy was formulated in 2010 and a new comprehensive nuclear law to replace the existing Atomic Energy Licensing Act (Act 304) is currently in the pipeline. Internationally, public acceptance is generally used to gauge the acceptance of nuclear energy by the public whenever a government decides to engage in nuclear energy. A public survey was conducted in between 14 March 2016 to 10 May 2016 focusing on the Malaysian public acceptance and perception towards the implementation of nuclear energy in Malaysia. The methodology of this research was aim on finding an overview of the general knowledge, public-relation recommendation, perception and acceptance of Malaysian towards the nuclear power development program. The combination of information gathered from this study can be interpreted as an indication of the complexity surrounding the development of nuclear energy and its relationship with the unique background of Malaysian demography. This paper will focus mainly on energy-related section in the survey in comparison with nuclear energy.

Since the event of Niigataken Chuetsu-oki Earthquake in 2007 and the subsequent press reports on damage of nuclear power station after it, a stance of media is being questioned. In order to clear this problem, basic organizational structure of the press related to nuclear energy news was analyzed. Local news department, social news department, science news department and economical news department involve in nuclear energy news the accordance with their own situations and concerns. This structure makes problem of nuclear energy news reporting complicated. Changing this system is required but very difficult. It is concluded that the press problem around nuclear energy news is strange. (author)

Nonlinear generalization of special relativity at very high energies

International Nuclear Information System (INIS)

Winterberg, F.

1984-01-01

It is shown, that the introduction of a fundamental length constant into the operator representation of the quantum mechanical commutation relations, as suggested by Bagge, leads to a nonlinear generalization of the Lorentz transformations. The theory requires the introduction of a substratum (ether) and which can be identified as the zero point vacuum energy. At very high energies a non-Lorentz invariant behaviour for the cross sections between elementary particles is predicted. Using the Einstein clock synchronisation definition, the velocity of light is also constant and equal to c in the new theory, but the zero point vacuum energy becomes finite, as are all other quantities which are divergent in Lorentz invariant quantum field theories. In the limiting case where the length constant is set equal to zero, the zero point vacuum energy diverges and special relativity is recovered. (orig.) [de

CO2 emissions, energy consumption, trade and income: A comparative analysis of China and India

Jayanthakumaran, Kankesu; Verma, Reetu; Liu Ying

2012-01-01

In order to prevent the destabilisation of the Earth's biosphere, CO 2 emissions must be reduced quickly and significantly. The causes of CO 2 emissions by individual countries need to be apprehended in order to understand the processes required for reducing emissions around the globe. China and India are the two largest transitional countries and growing economies, but are in two entirely different categories in terms of structural changes in growth, trade and energy use. CO 2 emissions from the burning of fossil fuels have significantly increased in the recent past. This paper compares China and India using the bounds testing approach to cointegration and the ARDL methodology to test the long- and short-run relationships between growth, trade, energy use and endogenously determined structural breaks. The CO 2 emissions in China were influenced by per capita income, structural changes and energy consumption. A similar causal connection cannot be established for India with regard to structural changes and CO 2 emissions, because India's informal economy is much larger than China's. India possesses an extraordinarily large number of micro-enterprises that are low energy consumers and not competitive enough to reach international markets. Understanding these contrasting scenarios is prerequisite to reaching an international agreement on climate change affecting these two countries. - Highlights: ► The bounds testing approach to cointegration and the ARDL methodology were used to test CO 2 emissions–energy consumption–income–international trade nexus in China and India. ► The CO 2 emissions in China were influenced by structural changes and associated energy consumption, income and foreign trade. ► A similar causal connection (structural change) cannot be established in India. ► Understanding these contrasting scenarios is prerequisite to reaching an international agreement on climate change affecting these countries.

Biophysical studies related to energy generation: Progress report

Green, A.E.S.

1988-01-01

This report covers work subsequent to our previous report of December 24, 1986. At that time we were groping to find relationships between vibrational and rotational electron impact cross sections in the vapor and liquid phases of water. Having reached an impass within the radiological literature, we drew upon the atmospheric, oceanographic and flame radiation literatures. Here a much broader body of excitation energy and intensity data related to the vibrational and rotational excitation of water in the vapor phases and liquid phases enabled us to identify certain ''big bands'' of H 2 O. These bands account for the major infrared absorption features observed in atmospheric transmission studies as well as important spectral radiation features observed in hydrocarbon combustion. Related liquid phase-gas phase involvement also entered our work on co-combustion of biomass and waste, and natural gas in studies directed toward contributing to the solution of national energy-environmental and economic problems. Attachments to this report include our published works, submitted works, and in complete studies related to radiological, atmospheric, and combustion studies which encompass biophysical studies related to energy generation and which have a common thread involving water in liquid and vapor form. These works are tied together in this brief report, along with some comments on trends in science and technology which they might illustrate

Space-time dependence between energy sources and climate related energy production

Science.gov (United States)

Engeland, Kolbjorn; Borga, Marco; Creutin, Jean-Dominique; Ramos, Maria-Helena; Tøfte, Lena; Warland, Geir

2014-05-01

The European Renewable Energy Directive adopted in 2009 focuses on achieving a 20% share of renewable energy in the EU overall energy mix by 2020. A major part of renewable energy production is related to climate, called "climate related energy" (CRE) production. CRE production systems (wind, solar, and hydropower) are characterized by a large degree of intermittency and variability on both short and long time scales due to the natural variability of climate variables. The main strategies to handle the variability of CRE production include energy-storage, -transport, -diversity and -information (smart grids). The three first strategies aim to smooth out the intermittency and variability of CRE production in time and space whereas the last strategy aims to provide a more optimal interaction between energy production and demand, i.e. to smooth out the residual load (the difference between demand and production). In order to increase the CRE share in the electricity system, it is essential to understand the space-time co-variability between the weather variables and CRE production under both current and future climates. This study presents a review of the literature that searches to tackle these problems. It reveals that the majority of studies deals with either a single CRE source or with the combination of two CREs, mostly wind and solar. This may be due to the fact that the most advanced countries in terms of wind equipment have also very little hydropower potential (Denmark, Ireland or UK, for instance). Hydropower is characterized by both a large storage capacity and flexibility in electricity production, and has therefore a large potential for both balancing and storing energy from wind- and solar-power. Several studies look at how to better connect regions with large share of hydropower (e.g., Scandinavia and the Alps) to regions with high shares of wind- and solar-power (e.g., green battery North-Sea net). Considering time scales, various studies consider wind

Modeling residential water and related energy, carbon footprint and costs in California

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

2015-01-01

Graphical abstract: - Highlights: • We model residential water use and related energy and GHG emissions in California. • Heterogeneity in use, spatial variability and water and energy rates are accounted. • Outdoor is more than 50% of water use but 80% of energy is used by faucet + shower. • Variability in water and energy prices affects willingness to adopt conservation. • Targeting high-use hoses and joint conservation policies are effective strategies. - Abstract: Starting from single-family household water end-use data, this study develops an end-use model for water-use and related energy and carbon footprint using probability distributions for parameters affecting water consumption in 10 local water utilities in California. Monte Carlo simulations are used to develop a large representative sample of households to describe variability in use, with water bills for each house for different utility rate structures. The water-related energy consumption for each household realization was obtained using an energy model based on the different water end-uses, assuming probability distributions for hot-water-use for each appliance and water heater characteristics. Spatial variability is incorporated to account for average air and household water inlet temperatures and price structures for each utility. Water-related energy costs are calculated using averaged energy price for each location. CO 2 emissions were derived from energy use using emission factors. Overall simulation runs assess the impact of several common conservation strategies on household water and energy use. Results show that single-family water-related CO 2 emissions are 2% of overall per capita emissions, and that managing water and energy jointly can significantly reduce state greenhouse gas emissions

Zou, B.; Yu, W.W.; Seo, J.; Zhu, T.; Hu, M.Z.

2012-01-01

During the past decades, nano crystals have attracted broad attention due to their unique shape- and size-dependent physical and chemical properties that differ drastically from their bulk counterparts. Hitherto, much effort has been dedicated to achieving rational controlling over the morphology, assembly, and related energy applications of the nano materials. Therefore, the ability to manipulate the morphology, size, and size distribution of inorganic nano materials is still an important goal in modern materials physics and chemistry. Especially, the world's demand for energy supply is causing a dramatic escalation of social and political unrest. Likewise, the environmental impact of the global climate change due to the combustion of fossil fuel is becoming increasingly alarming. These problems compel us to search for effective routes to build devices that can supply sustainable energy, with not only high efficiency but also environmental friendship. One of ways to relieve the energy crisis is to exploit devices based on renewable energy sources, such as solar energy and water power. Aiming at this exploration, the primary stage requires the design of appropriate strategies for the synthesis of high-quality nano crystals with respect to size uniformity and superior electrochemical performances. As a consequence, we organize the current special issue for Journal of Nano materials to provide the authors with a platform and readers with the latest achievements of nano crystals-related synthesis, assembly, and energy applications.

Energy-related indoor environmental quality research: A priority agenda

2002-08-01

A multidisciplinary team of IEQ and energy researchers has defined a program of priority energy-related IEQ research. This paper describes the methods employed to develop the agenda, and 35 high priority research and development (R&D) project areas related to four broad goals: (1) identifying IEQ problems and opportunities; (2) developing and evaluating energy-efficient technologies for improving IEQ; (3) developing and evaluating energy-efficient practices for improving IEQ; and (4) encouraging or assisting the implementation of technologies or practices for improving IEQ. The identified R&D priorities reflect a strong need to benchmark IEQ conditions in small commercial buildings, schools, and residences. The R&D priorities also reflect the need to better understand how people are affected by IEQ conditions and by the related building characteristics and operation and maintenance practices. The associated research findings will provide a clearer definition of acceptable IEQ that is required to guide the development of technologies, practices, standards, and guidelines. Quantifying the effects of building characteristics and practices on IEQ conditions, in order to provide the basis for development of energy efficient and effective IEQ control measures, was also considered a priority. The development or advancement in a broad range of IEQ tools, technologies, and practices are also a major component of the priority research agenda. Consistent with the focus on ''energy-related'' research priorities, building ventilation and heating, ventilating and air conditioning (HVAC) systems and processes are very prominent in the agenda. Research related to moisture and microbiological problems, particularly within hot and humid climates, is also prominent within the agenda. The agenda tends to emphasize research on residences, small commercial buildings, and schools because these types of buildings have been underrepresented in prior research. Most of

Implicit ligand theory for relative binding free energies

Science.gov (United States)

Nguyen, Trung Hai; Minh, David D. L.

2018-03-01

Implicit ligand theory enables noncovalent binding free energies to be calculated based on an exponential average of the binding potential of mean force (BPMF)—the binding free energy between a flexible ligand and rigid receptor—over a precomputed ensemble of receptor configurations. In the original formalism, receptor configurations were drawn from or reweighted to the apo ensemble. Here we show that BPMFs averaged over a holo ensemble yield binding free energies relative to the reference ligand that specifies the ensemble. When using receptor snapshots from an alchemical simulation with a single ligand, the new statistical estimator outperforms the original.

The nation, although not a party to the Montreal Protocol and Kyoto Protocol, has diligently strived to mitigate the emissions and phase out use of the responsible materials. Hydrofluorocarbons (HFCs), which are now mostly used in refrigeration and air conditioning systems, are the main GHGs associated with strong global warming potential. The objective of this paper is to present an overview of the industrial/commercial uses of HFCs in Taiwan. Because of their high impacts on climate change, the description is then centered on estimating the potential emissions of HFCs according to the Intergovernmental Panel on Climate Change (IPCC) method and the governmental organizations responses to the United Nations' Framework Convention on Climate Change (UNFCCC). The regulatory systems relating to HFCs mitigation and energy conservation and energy policies and promotion measures for providing technological assistances and financial incentives in the energy management, resource recovery and HFCs reduction/recycling technologies are also addressed in the paper

Energy fluxes and their relations within energy plants

Grazzini, Giuseppe; Milazzo, Adriano

Analysing how energy is delivered from its primary sources to final users, it may be seen that the evolution of technology, driven by economic considerations, has mainly rewarded those systems that have intense energy fluxes through their main sections. On the other hand, renewable energy sources are prevented from being widespread by their low energy density. If a high energy flux is a recognized target for energy use, one may try to characterise the various devices encountered along the energy path according to the concentration obtained of the energy flow. In this way, apart from measuring the energy loss suffered within a given device, it can be decided if this loss is adequate with respect to the gain in terms of energy density

Full Text Available The digital marketing environment is changing rapidly, and, for micro-enterprises, digital marketing is currently a vitally important opportunity. Attracting customers, engaging customers’ interest and participation, retaining customers, learning customers’ preferences and relating to customers are key strategies in building strong customer relationships. However, many enterprises ignore longer-term aspects of managing customer relationships. The study sought to contribute to a more in-depth understanding of micro-enterprises’ current strategies in terms of new digital marketing tools that foster stronger customer relationships. Based on interviews of two digital marketing service providers, this paper describes how their micro-enterprise clients use digital marketing tools through the five elements of building customer relationships. The findings highlight the importance of a practical understanding of digital marketing tools, as the digital marketing environment changes rapidly. The human capital and digital tool knowledge of micro-enterprises’ owner-managers have a great impact on these firms’ digital marketing and, ultimately, their success.

2016-01-01

Full Text Available The energy issue is a long-term one of the most discussed, controversial topics in relations between the European Union and the Russian Federation. The intention of the present article is an attempt to overcome the largely non-discursive and in the security conditions anchored way of looking at the energy interaction of the EU and the RF and through an integration discourse to analyze EU energy relations with Russia in the years 2004 - 2014. In the theoretical level, the article is based on a critical constructivism, which in relation to the discourse as the main concept reflects a number of fundamental knowledge. At the methodological level, the article is based on the discourse analysis as a basic methodological tool through which the author examines the EU text documents.

A Python tool to set up relative free energy calculations in GROMACS.

Science.gov (United States)

Klimovich, Pavel V; Mobley, David L

2015-11-01

Free energy calculations based on molecular dynamics (MD) simulations have seen a tremendous growth in the last decade. However, it is still difficult and tedious to set them up in an automated manner, as the majority of the present-day MD simulation packages lack that functionality. Relative free energy calculations are a particular challenge for several reasons, including the problem of finding a common substructure and mapping the transformation to be applied. Here we present a tool, alchemical-setup.py, that automatically generates all the input files needed to perform relative solvation and binding free energy calculations with the MD package GROMACS. When combined with Lead Optimization Mapper (LOMAP; Liu et al. in J Comput Aided Mol Des 27(9):755-770, 2013), recently developed in our group, alchemical-setup.py allows fully automated setup of relative free energy calculations in GROMACS. Taking a graph of the planned calculations and a mapping, both computed by LOMAP, our tool generates the topology and coordinate files needed to perform relative free energy calculations for a given set of molecules, and provides a set of simulation input parameters. The tool was validated by performing relative hydration free energy calculations for a handful of molecules from the SAMPL4 challenge (Mobley et al. in J Comput Aided Mol Des 28(4):135-150, 2014). Good agreement with previously published results and the straightforward way in which free energy calculations can be conducted make alchemical-setup.py a promising tool for automated setup of relative solvation and binding free energy calculations.

The Energy Charter Treaty and Related Documents. A Legal Framework for International Energy Cooperation

International Nuclear Information System (INIS)

2004-01-01

The Energy Charter Treaty is a unique instrument for the promotion of international cooperation in the energy sector. Following its entry into force on 16 April 1998, the Treaty, together with the related documents contained in this booklet, provides an important legal basis for the creation of an open international energy market. The Charter process includes the countries of the enlarged European Union, Central and Eastern Europe, the Russian Federation, Central Asia and the Caucasus, as well as Japan, Australia and Mongolia. The Treaty remains open for accession by all countries committed to observance of its principles. It is very positive in this regard that states such as China, Iran, South Korea and the countries of ASEAN are taking a close interest in the Charter process, thus opening up the prospect of a further extension of its geographical scope. The primary challenge facing the constituent members of the Energy Charter process in the coming years will be that of ensuring full implementation of the Treaty's commitments. This will entail increased focus on multilateral cooperation over transit, trade, investments, environmental protection and energy efficiency. By continuing to build on its existing work in these areas, the Charter process stands ready to play a key role in translating the aim of a truly open non-discriminatory energy market into reality. This publication reproduces the text of the following documents: Final Act of the European Energy Charter Conference with all Annexes thereto, as opened for signature in Lisbon on 17 December 1994 and corrected by the Protocol of Correction of 2 August 1996; the Chairman's Statement at Adoption Session on 17 December 1994, as reported in the Note from the Secretariat 42/94 CONF 115; the Joint Memorandum of the Delegations of the Russian Federation and the European Communities on Nuclear Trade, as reported in the Note from the Secretariat 42/94 CONF 115; the Concluding Document of the Hague Conference on

A Comprehensive Energy Analysis and Related Carbon Footprint of Dairy Farms, Part 1: Direct Energy Requirements

Directory of Open Access Journals (Sweden)

Giuseppe Todde

2018-02-01

Full Text Available Dairy cattle farms are continuously developing more intensive systems of management which require higher utilization of durable and not-durable inputs. These inputs are responsible of significant direct and indirect fossil energy requirements which are related to remarkable emissions of CO2. This study aims to analyze direct energy requirements and the related carbon footprint of a large population of conventional dairy farms located in the south of Italy. A detailed survey of electricity, diesel and Liquefied Petroleum Gas (LPG consumptions has been carried out among on-farm activities. The results of the analyses showed an annual average fuel consumption of 40 kg per tonne of milk, while electricity accounted for 73 kWh per tonne of milk produced. Expressing the direct energy inputs as primary energy, diesel fuel results the main resource used in on-farm activities, accounting for 72% of the total fossil primary energy requirement, while electricity represents only 27%. Moreover, larger farms were able to use more efficiently the direct energy inputs and reduce the related emissions of carbon dioxide per unit of milk produced, since the milk yield increases with the herd size. The global average farm emissions of carbon dioxide equivalent, due to all direct energy usages, accounted for 156 kg CO2-eq per tonne of Fat and Protein Corrected Milk (FPCM, while farms that raise more than 200 heads emitted 36% less than the average value. In this two-part series, the total energy demand (Part 1 + Part 2 per farm is mainly due to agricultural inputs and fuel consumption, which have the largest quota of the annual requirements for each milk yield class. These results also showed that large size farms held lower CO2-eq emissions when referred to the mass of milk produced.

Dynamics of energy-related CO2 emissions in China during 1980-2002: the relative importance of energy supply-side and demand-side effects

Libo Wu; Kaneko, Shinji; Matsuoka, Shunji

2006-01-01

Based on a newly developed model that integrates energy production, transformation and consumption processes, this paper compares the relative importance of some traditionally recognized factors operating on the energy demand side with a body of newly defined factors on the supply side, in terms of their contribution to trends in China's CO 2 emissions related to the total primary energy supply (C-TPES). Before 1996, changes in China's C-TPES were mainly driven by changes on the energy demand side. Factors operating on the energy supply side played trivial roles. During the period 1996-2000, however, increasing demand-side effects declined dramatically and at the same time decreasing effects from supply side expanded significantly. Such changes resulted directly in a decline in the C-TPES. The decreasing effects from international trade as well as statistical imbalances between supply and demand reinforced the declining trend. The shrinkage of demand side effects mainly arose from the slowdown of economic growth and speed of decrease in energy intensity. The expansion of supply-side effects was principally attributed to the speed of decrease in gross unit consumption in transformation sectors, especially in electricity sector. Therefore, the acceleration of efficiency improvements in end-use and transformation sectors accounted for the decline in the C-TPES over the period 1996-2000. (author)

Regulatory problems relating to energy in Hungary

International Nuclear Information System (INIS)

Remenyi, K.

2002-01-01

One of basic problems of the transition in the energy economy is, how far the process of liberalisation and privatisation could go, i.e. to what extent the control of state/government would be given up, and how the breakdown of the commanding positions of the government would be managed. The transition in the energy sector toward a market economy is characterised by restructuring the regulatory framework of the energy industry, changing the operational structure of the sector and profound reshaping of ownership structures of the enterprises. In Hungary the government, being convinced of the importance of the implementation of the market forces, in 1991 made the first step on the way of restructuring the energy sector in order to increase economic efficiency, to enable companies to react to market forces and to privatise them. Parallel and partly after the restructuring, a profound modification of legal and regulatory framework took place and finally a relatively large scale of privatisation has newly emerged, which will continue in future, too. The process of the energy sector liberalisation in Hungary has a stop and go character and the game is not over. The process can be characterised by institutional restructuring in the energy sector (coal, oil/gas, power ), which is the basic condition for market liberalisation and privatisation, and by the creation of an appropriate environment (regulatory framework, pricing policy, etc. ) for the smooth implementation of the liberation process(author)

A time-series analysis of energy-related carbon emissions in Korea

International Nuclear Information System (INIS)

Ki-Hong Choi; Ang, B.W.

2001-01-01

Energy-related carbon emissions and their relationships with energy consumption and GNP in Korea are studied from 1961 to 1998. The ratio of carbon emissions to GNP is expressed as the product of the aggregate carbon factor and the energy intensity. Changes in the aggregate carbon factor are decomposed into the impacts associated with the fuel carbon factor and the fuel mix, using the Divisia index approach. The analysis is carried out using two sets of data, with and without wood consumption as an energy source, and very different results are obtained. This shows that carbon emission studies for developing countries based on commercial energy consumption only may have to be interpreted with caution. Our analysis also reveals that the impact of the energy intensity on carbon emissions is greater than that of the aggregate carbon factor. This finding supports the assertion made in earlier studies that the energy intensity is a more meaningful indicator than the aggregate carbon factor in the study of climate change resulting from energy-related emissions.

Markets, jobs, and energetic challenge of activities related to renewable energies and to energy efficiency. Situation in 2007-2008. Perspectives for 2009

International Nuclear Information System (INIS)

2009-10-01

This study proposes an annual evolution survey of markets and jobs related to the development of renewable energies and to the improvement of energy efficiency in the housing and transport sectors. Markets are related to wind energy, thermal and photovoltaic energy, heat pumps, wood, bio-diesel, bio-ethanol, biogas, waste energetic valorization, geothermal energy, and hydro-energy. Energy efficiency improvements in the housing sector are related to energetic improvement of existing dwellings, condensing boilers, energetically performing household electrical appliances, and compact fluorescent lamps. In the transport sector, energy efficiency improvements concern rail transports and tramways as well as individual vehicles. New markets are identified and discussed: research and development for renewable energies, energy consultancy and diagnosis, energy efficiency in the office building sector and in the industrial sector

An assessment of worldwide energy-related atmospheric pollution

International Nuclear Information System (INIS)

1989-01-01

Energy-related emissions of atmospheric pollutants are currently suspected as the source of a number of major environmental problems. Early concerns about local and regional air quality and respiratory health risks, greatly alleviated in the case of sulfur dioxide (SO 2 ) emissions by the use of tall stacks, have been superseded by ''global problems,'' such as acidification of the biosphere, increase in tropospheric ozone (O 3 ), visibility impairment, long-term exposure to toxic pollutants, and buildup of ''greenhouse gases''. Chapter 1 assesses the sources and physical/chemical atmospheric processes of energy-related atmospheric pollution (ERAP). It is not an exhaustive review but rather a documented statement of the state-of-art knowledge on issues critical to effective environmental decision-making. Chapter 2 looks at the effects on man, the environment and materials, and chapter 3 presents an overview and policy options. (author)

Measurability of quantum fields and the energy-time uncertainty relation

International Nuclear Information System (INIS)

Mensky, Mikhail B

2011-01-01

Quantum restrictions on the measurability of an electromagnetic field strength and their relevance to the energy-time uncertainty relation are considered. The minimum errors in measuring electromagnetic field strengths, as they were estimated by the author (1988) in the framework of the phenomenological method of restricted path integral (RPI), are compared with the analogous estimates found by Landau and Peierls (1931) and by Bohr and Rosenfeld (1933) with the help of certain measurement setups. RPI-based restrictions, including those of Landau and Peierls as a special case, hold for any measuring schemes meeting the strict definition of measurement. Their fundamental nature is confirmed by the fact that their associated field detectability condition has the form of the energy-time uncertainty relation. The weaker restrictions suggested by Bohr and Rosenfeld rely on an extended definition of measurement. The energy-time uncertainty relation, which is the condition for the electromagnetic field to be detectable, is applied to the analysis of how the near-field scanning microscope works.

Implantable Cardioverter-Defibrillator (ICD) shocks have been associated with mortality. However, no study has examined the relation between total shock energy and mortality. The aim of this study is to assess the association of total shock energy with mortality, and to determine the patients who are at risk of this association. Data from 316 consecutive patients who underwent initial ICD implantation in our hospital between 2000 and 2011 were retrospectively studied. We collected shock energy for 3 years from the ICD implantation, and determined the relation of shock energy on mortality after adjusting confounding factors. Eighty-seven ICD recipients experienced shock(s) within 3 years from ICD implantation and 43 patients had died during the follow-up. The amount of shock energy was significantly associated with all-cause death [adjusted hazard ratio (HR) 1.26 (per 100 joule increase), p energy accumulation (≥182 joule) was lower (p energy accumulation (energy accumulation and all-cause death was remarkable in the patients with low left ventricular ejection fraction (LVEF ≤40%) or atrial fibrillation (AF). Increase of shock energy was related to mortality in ICD recipients. This relation was evident in patients with low LVEF or AF. Copyright © 2018 Elsevier B.V. All rights reserved.

Nuclear energy: strategy of public relations

A referendum was held in Sweden on 23rd March 1980, stimulated by the Three Mile Island accident in USA, to determine the future nuclear power development policy. The electricity supply background is that in 1980, 65% of power was hydro, 25% nuclear and 10% coal and oil. In terms of total power consumption, the country is heavily dependent on oil, which represents about 75%. The intensive public relations activity previous to the referendum is described, and this involved fact accumulation and assimilation, dissemination through various media, including brochures, displays, films and leaflets. In the political arena three lines developed: (1) (Conservatives); continue nuclear power, building at least 12 reactors, (2) (Social democrats and liberals); similar to (1), but more cautious, with emphasis on energy conservation, (3) (Centre parties and communists); no more nuclear power, and prevention of uranium extraction in Sweden. The voting was (1) 18.9%, (2) 39.1%, (3) 38.7%, (No dec of the most topical is concerned with the inventory of risks due to each industrial energy sector. This session was in two parts, the first devoted to problems specific to each source of energy including nuclear, the second to commo The extension to longer distances may be made with caution and to the satisfaction of the regulatory authority.

Cooperative Agreements, DE-FC26-08NT43293, DOE-WRI Cooperative Research and Development Program for Fossil Energy-Related Resources began in June 2009. The goal of the Program was to develop, commercialize, and deploy technologies of value to the nation’s fossil and renewable energy industries. To ensure relevancy and early commercialization, the involvement of an industrial partner was encouraged. In that regard, the Program stipulated that a minimum of 20% cost share be achieved in a fiscal year. This allowed WRI to carry a diverse portfolio of technologies and projects at various development technology readiness levels. Depending upon the maturity of the research concept and technology, cost share for a given task ranged from none to as high as 67% (two-thirds). Over the course of the Program, a total of twenty six tasks were proposed for DOE approval. Over the period of performance of the Cooperative agreement, WRI has put in place projects utilizing a total of $7,089,581 in USDOE funds. Against this funding, cosponsors have committed $7,398,476 in private funds to produce a program valued at $14,488,057. Tables 1 and 2 presented at the end of this section is a compilation of the funding for all the tasks conducted under the program. The goal of the Cooperative Research and Development Program for Fossil Energy-Related Resources was to through collaborative research with the industry, develop or assist in the development of innovative technology solutions that will: • Increase the production of United States energy resources – coal, natural gas, oil, and renewable energy resources; • Enhance the competitiveness of United States energy technologies in international markets and assist in technology transfer; • Reduce the nation's dependence on foreign energy supplies and strengthen both the United States and regional economies; and • Minimize environmental impacts of energy production and utilization. Success of the Program can be measured by

Hamiltonian Dynamics and Positive Energy in General Relativity

Deser, S. [Physics Department, Brandeis University, Waltham, MA (United States)

1969-07-15

A review is first given of the Hamiltonian formulation of general relativity; the gravitational field is a self-interacting massless spin-two system within the framework of ordinary Lorentz covariant field theory. The recently solved problem of positive-definiteness of the field energy is then discussed. The latter, a conserved functional of the dynamical variables, is shown to have only one extremum, a local minimum, which is the vacuum state (flat space). This implies positive energy for the field, with the vacuum as ground-state. Similar results hold when minimally coupled matter is present. (author)

Nutritional needs, and trends in food and energy demand per capita are also indicated. Some emerging constraints in relation to soil fertility and agrochemical usage are identified. A growing pressure on land for ''energy and chemical farming'' is foreseen. Losses of native and added soil nitrogen, comparable with total industrial fertilizer nitrogen fixation, seem unavoidable for two decades at least. This consideration of trends and their interactions suggests the need for more effective interdisciplinary study, longer-term planning and international cooperation.

With rapid economic development and energy consumption growth, China has become the largest energy consumer in the world. Impelled by extensive international concern, there is an urgent need to analyze the characteristics of energy consumption and related carbon emission, with the objective of saving energy, reducing carbon emission, and lessening environmental impact. Focusing on urban ecosystems, the biggest energy consumer, a method for estimating energy consumption and related carbon emission was established at the urban sector scale in this paper. Based on data for 1996-2010, the proposed method was applied to Beijing in a case study to analyze the consumption of different energy resources (i.e., coal, oil, gas, and electricity) and related carbon emission in different sectors (i.e., agriculture, industry, construction, transportation, household, and service sectors). The results showed that coal and oil contributed most to energy consumption and carbon emission among different energy resources during the study period, while the industrial sector consumed the most energy and emitted the most carbon among different sectors. Suggestions were put forward for energy conservation and emission reduction in Beijing. The analysis of energy consumption and related carbon emission at the sector scale is helpful for practical energy saving and emission reduction in urban ecosystems.

The additive-manufacturing (AM) technique, known as three-dimensional (3D) printing, has attracted much attention in industry and academia in recent years. 3D printing has been developed for a variety of applications. Printable inks are the most important component for 3D printing, and are related to the materials, the printing method, and the structures of the final 3D-printed products. Carbon materials, due to their good chemical stability and versatile nanostructure, have been widely used in 3D printing for different applications. Good inks are mainly based on volatile solutions having carbon materials as fillers such as graphene oxide (GO), carbon nanotubes (CNT), carbon blacks, and solvent, as well as polymers and other additives. Studies of carbon materials in 3D printing, especially GO-based materials, have been extensively reported for energy-related applications. In these circumstances, understanding the very recent developments of 3D-printed carbon materials and their extended applications to address energy-related challenges and bring new concepts for material designs are becoming urgent and important. Here, recent developments in 3D printing of emerging devices for energy-related applications are reviewed, including energy-storage applications, electronic circuits, and thermal-energy applications at high temperature. To close, a conclusion and outlook are provided, pointing out future designs and developments of 3D-printing technology based on carbon materials for energy-related applications and beyond. © 2016 WILEY-VCH Verlag GmbH & Co.

The Eastern Partnership and the EU-Turkey Energy Relations

Demiryol Tolga

2014-10-01

Full Text Available This article discusses the prospects and challenges of energy cooperation between the European Union (EU and Turkey within the context of the Eastern Partnership (EaP. Part of the EaP agenda is to advance energy cooperation between the EU and the partner states, particularly regarding the diversification of import routes. As an energy corridor between the EU and the hydrocarbon-rich Caspian states, Turkey is a strategic asset for European energy security. Turkey also has economic ties and political capital in the Caspian region that can help the EU reach out to its eastern partners. Despite robust incentives for cooperation, however, the EU-Turkey energy partnership has so far failed to meet mutual expectations. This article argues that this is primarily due to the inability of the two actors to credibly commit to regional energy cooperation. Commitment problem stems from two factors. First, the predominance of national energy interests over communal ones undermines credible commitment. The variation in energy needs of Member States prevents the EU from acting in unison in external energy policy. Similarly, Turkey also prioritizes its own energy security, particularly in its relations with suppliers, which undermines cooperation with the EU. Second, the EU and Turkey hold divergent perspectives on the potential political payoffs of energy cooperation. Turkish decision makers are convinced that energy cooperation warrants palpable progress in Turkey’s accession while most EU actors appear hesitant to establish a direct connection between energy and accession.

Full Text Available Highly intensive internalization of the world economy requires the business sector to have different view of strategic management and decision making, together with the quality and content of business processes. Changes in the environment of enterprises significantly influence their function and behaviour, causing a need to significantly change enterprise architecture, including the design of development strategies. The paper focuses on analysing the processes of industrial enterprises, dealing with their importance and profit, classified by size. The result revealed that process activities, such as input logistics and marketing, are dominant in micro-enterprises, and such activities are important in profitable enterprises. In middle-sized enterprises, there is a more significant difference between marketing/sales and services without any relations to profit. However, there is a requirement to intensify these activities in non-profitable enterprises. Large enterprises revealed a significant influence of the scientific and technological development and also, to a lesser extent, of marketing, sales and purchase. Non-profitable enterprises should also focus on improving the quality of such processes.

Energy Democracies and Publics in the Making: A Relational Agenda for Research and Practice

Directory of Open Access Journals (Sweden)

Jason Chilvers

2018-04-01

Full Text Available Mainstream approaches to energy democracy and public engagement with energy transitions tend to adopt specific, pre-given meanings of both “democracy” and “publics.” Different approaches impose prescriptive assumptions about the model of participation, the identity of public participants, and what it means to participate well. The rigidity of many existing approaches to energy participation is increasingly being challenged by the ever-multiplying diversity of ways in which citizens participate in energy systems, as consumers in energy markets, protesters against new infrastructures and technologies, as initiators of community energy projects, and as subjects of behavior change interventions, amongst others. This paper is concerned with growing areas of scholarship which seek to understand and explore these emerging energy publics and forms of energy democracy from a relational perspective. Such work, grounded in constructivist and relational ontologies, views forms of participatory democracy and publics as being co-produced, constructed, and emergent through the performance of collective practices. It pays closer attention to power relations, politics, materiality, exclusions, and effects in both understanding and intervening in the making of energy democracy. This in turn shifts the focus from studying discrete unitary forms of “energy democracy” to one of understanding interrelations between multiple diverse energy democracies in wider systems. In this paper, we chart these developments and explore the significant challenges and potential contributions of relational approaches to furthering the theories, methods, and practices of energy democracy and energy public engagement. The paper draws on an expert workshop, and an accompanying review, which brought together leading proponents of contending relational approaches to energy participation in direct conversation for the first time. We use this as a basis to explore tensions

SOME LEGAL ASPECTS OF ENERGY SECURITY IN THE RELATIONS BETWEEN EU AND RUSSIA

Directory of Open Access Journals (Sweden)

Full Text Available The need for a sustainable, secure and competitive energy supply has long been recognized within the Community, and has been addressed on numerous occasions, notably in the Green Papers elaborated by the Commission in 2000 and 2006. Recent supply crises and rapidly escalating fuel prices have focused the minds of leaders across the European Union, as well as those of businesses and individual energy consumers. Energy policy transcends a range of different policy areas, including competition, transport, environment and energy itself. Decisions relating to energy policy in Europe are primarily within the remit of individual Member State governments, with the European Commission’s powers limited to two specific areas (creation of the European single market and matters relating to nuclear safety and security under the EURATOM Treaty. The extent of the transfer of powers towards Europe is clearly a critical decision point and in practice a sensitive balance is likely to be required between those matters for which the Commission should have responsibility and those where Member State governments retain sole authority. European officials are putting into evidence their belief that Europe’s energy predicament is acute and mention energy security as a priority issue for the Common Foreign and Security Policy. Policy commitments say that energy strategy must move beyond the internal sphere and become systematically a part of EU external relations. The Commission’s 2006 Energy Green Paper promised “a better integration of energy objectives into broader relations with third countries”.

Public support for energy sources and related technologies: The impact of simple information provision

International Nuclear Information System (INIS)

Hobman, Elizabeth V.; Ashworth, Peta

2013-01-01

Increasing public awareness and understanding of alternative energy sources and related technologies is an essential component of informed decision-making regarding new options of generating energy for a low carbon future. The current study examined the influence of psychological factors (i.e., pro-environmental beliefs, and subjective norms) and the provision of factual information on public support for a range of energy sources and related technologies. A representative sample of 1907 Australians completed an on-line survey that measured perceptions of a range of climate change and energy issues. Results showed that support for renewables is stronger than support for traditional fossil-fuel based energy sources (i.e., coal or gas) or nuclear energy. The provision of factual information about generation cost and emissions significantly changed support ratings, particularly when cost information was provided. Regression analyses revealed that pro-environmental beliefs were significantly related to support ratings for alternative energy sources. Subjective norms, however, were the strongest positive explanatory factor, suggesting that social mechanisms may be key drivers of support for new and emerging energy sources and related technologies. - Highlights: • We examine support for a wide range of energy sources and technologies. • Support changes when information on cost and emissions is provided. • Pro-environmental beliefs and social norms positively relate to support

2002-01-01

We study the IR-UV connection in noncommutative φ 3 theory as well as in noncommutative QED from the point of view of the dispersion relation for self-energy. We show that, although the imaginary part of the self-energy is well behaved as the parameter of noncommutativity vanishes, the real part becomes divergent as a consequence of the high energy behavior of the dispersion integral. Some other interesting features that arise from this analysis are also briefly discussed

This study assesses the potential of mediation as a tool for resolving disputes related to the environmental regulation of new energy facilities and identifies possible roles the Federal government might play in promoting the use of mediation. These disputes result when parties challenge an energy project on the basis of its potential environmental impacts. The paper reviews the basic theory of mediation, evaluates specific applications of mediation to recent environmental disputes, discusses the views of environmental public-interest groups towards mediation, and identifies types of energy facility-related disputes where mediation could have a significant impact. Finally, potential avenues for the Federal government to encourage use of this tool are identified.

Energy efficiency and the influence of gas burners to the energy related carbon dioxide emissions of electric arc furnaces in steel industry

Kirschen, Marcus; Risonarta, Victor; Pfeifer, Herbert

2009-01-01

Determining the complete energy balance of an electric arc furnace (EAF) provides an appropriate method to examine energy efficiency and identify energy saving potentials. However, the EAF energy balance is complex due to the combined input of electrical energy and chemical energy resulting from natural gas (NG) combustion and oxidation reactions in the steel melt. In addition, furnace off-gas measurements and slag analysis are necessary to reliably determine energy sinks. In this paper 70 energy balances and energy efficiencies from multiple EAFs are presented, including data calculated from plant measurements and compiled from the literature. Potential errors that can be incorporated in these calculations are also highlighted. The total energy requirement of these modern EAFs analysed ranged from 510 to 880 kWh/t, with energy efficiency values (η = ΔH Steel /E Total ) of between 40% and 75%. Furthermore, the focus was placed on the total energy related CO 2 emissions of EAF processes comprising NG combustion and electrical energy input. By assessing multiple EAF energy balances, a significant correlation between the total energy requirement and energy related specific CO 2 emissions was not evident. Whilst the specific consumption of NG in the EAF only had a minor impact on the EAF energy efficiency, it decreased the specific electrical energy requirement and increased EAF productivity where transformer power was restricted. The analysis also demonstrated that complementing and substituting electrical energy with NG was beneficial in reducing the total energy related CO 2 emissions when a certain level of substitution efficiency was achieved. Therefore, the appropriate use of NG burners in modern EAFs can result in an increased EAF energy intensity, whilst the total energy related CO 2 emissions remain constant or are even decreased.

Energy and greenhouse gas management in urban water systems typically focus on optimising within the direct system boundary of water utilities that covers the centralised water supply and wastewater treatment systems, despite a greater energy influence by the water end use. This work develops a cost curve of water-related energy management options from a city perspective for a hypothetical Australian city. It is compared with that from the water utility perspective. The curves are based on 18 water-related energy management options that have been implemented or evaluated in Australia. In the studied scenario, the cost-effective energy saving potential from a city perspective (292 GWh/year) is far more significant than that from a utility perspective (65 GWh/year). In some cases, for similar capital cost, if regional water planners invested in end use options instead of utility options, a greater energy saving potential at a greater cost-effectiveness could be achieved in urban water systems. For example, upgrading a wastewater treatment plant for biogas recovery at a capital cost of $27.2 million would save 31 GWh/year with a marginal cost saving of $63/MWh, while solar hot water system rebates at a cost of $28.6 million would save 67 GWh/year with a marginal cost saving of $111/MWh. Options related to hot water use such as water-efficient shower heads, water-efficient clothes washers and solar hot water system rebates are among the most cost-effective city-scale opportunities. This study demonstrates the use of cost curves to compare both utility and end use options in a consistent framework. It also illustrates that focusing solely on managing the energy use within the utility would miss substantial non-utility water-related energy saving opportunities. There is a need to broaden the conventional scope of cost curve analysis to include water-related energy and greenhouse gas at the water end use, and to value their management from a city perspective.

Energy underreporting occurs in 2% to 85% and overreporting in 1% to 39% of various populations. Efforts are needed to understand the psychosocial and behavioral characteristics associated with misreporting to help improve the accuracy of dietary self-reporting. Past research suggests that higher social desirability and greater eating restraint are key factors influencing misreporting, while a history of dieting and being overweight are more moderately associated. Eating disinhibition, body image, depression, anxiety, and fear of negative evaluation may be related to energy misreporting, but evidence is insufficient. This review will provide a detailed discussion of the published associations among psychosocial and behavioral characteristics and energy misreporting.

Full Text Available Low energy density diet, high in fruits and vegetables, is related to lower obesity risk and to better health status, but is more expensive. High energy density diet, high in added sugar and fats, is more affordable, but is related to higher obesity and chronic diseases risk. The aim of this study was to report prices according to energy density (low vs. high of food items and to show how food affordability could affect food choice and consumers’ health. Data was collected for 137 raw and processed foods from three purchase sites in Zagreb (one representative for supermarket, one smaller shop and green market. Results showed that low energy density food is more expensive than high energy density food (for example, the price of 1000 kcal from green zucchini (15 kcal/100 g is 124.20 kn while the price of 1000 kcal from sour cream (138 kcal/100 g is 13.99 kn. Food energy price was significantly different (p<0.05 between food groups with highest price for vegetable products (159.04 ± 36.18 kn/1000 kcal and raw vegetables (97.90 ± 50.13 kn/1000 kcal and lowest for fats (8.49 ± 1.22 kn/1000 kcal and cereals and products (5.66 ± 0.76 kn/1000 kcal. Negative correlation (Spearman r=-0.72, p<0.0001 was observed for energy density (kcal/100 g and price of 1000 kcal. Therefore, it is advisable to develop strategies in order to reduce price of low energy density food and encourage its intake since it would improve diet quality, which could lead to better costumers’ health.

Boundary conditions, energies and gravitational heat in general relativity (a classical analysis)

International Nuclear Information System (INIS)

Francaviglia, M; Raiteri, M

2004-01-01

The variation of the energy for a gravitational system is directly defined from the Hamiltonian field equations of general relativity. When the variation of the energy is written in a covariant form, it splits into two (covariant) contributions: one of them is the Komar energy, while the other is the so-called covariant ADM correction term. When specific boundary conditions are analysed one sees that the Komar energy is related to the gravitational heat while the ADM correction term plays the role of the Helmholtz free energy. These properties allow one to establish, inside a classical geometric framework, a formal analogy between gravitation and the laws governing the evolution of a thermodynamical system. The analogy applies to stationary spacetimes admitting multiple causal horizons as well as to AdS Taub-bolt solutions

Matching of energy-supply system and demand system is very important in dealing with the energy problem. Especially the energy-demand system is important for determing the quantity and quality of the energy demand. The energy demand is created by activities of industry and human life. The best materials which describe these activity conditions is the interindustry-relations table. Authors rely on this table as the basic data for assuming the energy demand analysis of energy system. The defect of this table is that an industrial classification differs in publishing years. So the table is lacking in the time sequential consistency. Therefore we discuss the method to improve the defect in consistency. In addition, this report analyses the energy demand structure in Japan according to the improved method. The research is done by the following procedure, 1. The unified common sector data is made so that an industrial classification in the interindustry-relations tables become common. 2. The quantity of input energy in each section is extracted from the tables. 3. The input energy is converted into the characteristic indicator and the calorific indicator. 4. The section is united using the common sector data. 5. The result is shown in table or graph. 6. The energy demand structure is analyzed based on the tables and the graphs. This interindustry-relations table is offered by request in the form of the magnetic tape. All the data is processed by computer due to the abundant amount of data. This report shows the idea how to process the fable instead of displaying the details. In addition, the problem in the analysis of the table is pointed out as results of the analysis. This report describes the feature of 23-sections classification in analysis of the energy demand structure. This report offers a basic data to make energy scenario to the energy system analysists.

2017-01-01

States implement clean energy-related economic development policy to spur innovation, manufacturing, and to address other priorities. This report focuses on those policies most directly related to expanding new and existing manufacturing. The extent to which states invest in this policymaking depends on political drivers and jurisdictional economic development priorities. To date, no one source has collected all of the clean energy-related economic development policies available across the 50 states. Thus, it is unclear how many policies exist within each state and how these policies, when implemented, can drive economic development. Establishing the baseline of existing policy is a critical first step in determining the potential holistic impact of these policies on driving economic growth in a state. The goal of this report is to document the clean energy-related economic development policy landscape across the 50 states with a focus on policy that seeks to expand new or existing manufacturing within a state. States interested in promoting clean energy manufacturing in their jurisdictions may be interested in reviewing this landscape to determine how they compare to peers and to adjust their policies as necessary. This report documents over 900 existing clean energy-related economic development laws, financial incentives (technology-agnostic and clean energy focused), and other policies such as agency-directed programs and initiatives across the states.

Long term energy-related environmental issues of copper production

International Nuclear Information System (INIS)

Alvarado, S.; Maldonado, P.; Barrios, A.; Jaques, I.

2002-01-01

Primary copper production is a major activity in the mining sector of several countries. However, it is highly energy-intensive and poses important environmental hazards. In the case of Chile, the world's largest copper producer (40% of world total), we examine its energy consumption and energy-related environmental implications over a time horizon of 25 years. Concerning the latter, we focus on greenhouse-gas (GHG) emissions, one of the most debated environmental issues. This paper follows up our previous report in which the current situation was analyzed and a particular technical option for improving the energy efficiency and concurrently reducing GHG emissions was discussed. Estimated reference or base (BS) and mitigation (MS) scenarios are developed for the period ending in 2020. The former assesses the energy demand projected in accordance with production forecasts and specific energy consumption patterns (assuming that energy efficiency measures are adopted 'spontaneously') with their resultant GHG emissions, while the latter assumes induced actions intended to reduce emissions by adopting an aggressive policy of efficient energy use. For the year 2020, the main results are: (i) BS, 1214 t of CO 2 /ton of refined copper content (49% lower than in 1994); (ii) MS, 1037 t of CO 2 /t of refined copper content (56% lower than in 1994). CO 2 emissions have been estimated considering both fuel and electricity process requirements. (author)

A three-dimensional harmonic oscillator consisting of N ≥2 Coulomb-interacting charged particles, often called a (many-electron) Hooke atom, is a popular model in computational physics for, e.g., semiconductor quantum dots and ultracold ions. Starting from Thomas-Fermi theory, we show that the ground-state energy of such a system satisfies a nontrivial relation: Eg s=ω N4 /3fg s(β N1 /2) , where ω is the oscillator strength, β is the ratio between Coulomb and oscillator characteristic energies, and fg s is a universal function. We perform extensive numerical calculations to verify the applicability of the relation. In addition, we show that the chemical potentials and addition energies also satisfy approximate scaling relations. In all cases, analytic expressions for the universal functions are provided. The results have predictive power in estimating the key ground-state properties of the system in the large-N limit, and can be used in the development of approximative methods in electronic structure theory.

Modelling lifestyle effects on energy demand and related emissions

International Nuclear Information System (INIS)

Weber, C.

2000-01-01

An approach to analyse and quantify the impact of lifestyle factors on current and future energy demand is developed. Thereby not only directly environmentally relevant consumer activities such as car use or heating have been analysed, but also expenditure patterns which induce environmental damage through the production of the consumed goods. The use of household survey data from the national statistical offices offers the possibility to cover this wide range of activities. For the available social-economic household characteristics a variety of different behavioural patterns have been observed. For evaluating the energy and emission consequences of the consumed goods enhanced input-output models are used. The additions implemented - a mixed monetary-energetic approach for inter-industry flows and a separate treatment of transport -related emissions - improve the reliability of the obtained results. The developed approach has been used for analysing current emissions profiles and distributions in West Germany, France and the Netherlands as well as scenarios for future energy demand and related emissions. It therefore provides a comprehensive methodology to analyse environmental effects in a consumer and citizen perspective and thus contributes to an increase transparency of complex economic and ecological interconnections.

The capabilities of the polarizable force fields for alchemical free energy calculations have been limited by the high computational cost and complexity of the underlying potential energy functions. In this work, we present a GPU-based general alchemical free energy simulation platform for polarizable potential AMOEBA. Tinker-OpenMM, the OpenMM implementation of the AMOEBA simulation engine has been modified to enable both absolute and relative alchemical simulations on GPUs, which leads to a ∼200-fold improvement in simulation speed over a single CPU core. We show that free energy values calculated using this platform agree with the results of Tinker simulations for the hydration of organic compounds and binding of host-guest systems within the statistical errors. In addition to absolute binding, we designed a relative alchemical approach for computing relative binding affinities of ligands to the same host, where a special path was applied to avoid numerical instability due to polarization between the different ligands that bind to the same site. This scheme is general and does not require ligands to have similar scaffolds. We show that relative hydration and binding free energy calculated using this approach match those computed from the absolute free energy approach. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Universal binding energy relation for cleaved and structurally relaxed surfaces.

2014-02-05

The universal binding energy relation (UBER), derived earlier to describe the cohesion between two rigid atomic planes, does not accurately capture the cohesive properties when the cleaved surfaces are allowed to relax. We suggest a modified functional form of UBER that is analytical and at the same time accurately models the properties of surfaces relaxed during cleavage. We demonstrate the generality as well as the validity of this modified UBER through first-principles density functional theory calculations of cleavage in a number of crystal systems. Our results show that the total energies of all the relaxed surfaces lie on a single (universal) energy surface, that is given by the proposed functional form which contains an additional length-scale associated with structural relaxation. This functional form could be used in modelling the cohesive zones in crack growth simulation studies. We find that the cohesive law (stress-displacement relation) differs significantly in the case where cracked surfaces are allowed to relax, with lower peak stresses occurring at higher displacements.

Full Text Available This study investigated the effect of economic vulnerability upon competitive advantages, performance, and sustainability of micro-enterprises owned and managed by micro-entrepreneurs who participate in varied development initiatives in Peninsular Malaysia. Upon adopting the cross-sectional design, data were randomly collected from selected 300 micro-entrepreneurs from the eKasih program (national poverty data bank located in four states of Peninsular Malaysia. The quantitative data were collected by conducting structured interview sessions with the respondents held from September until November 2017. The findings revealed that the state of economic vulnerability among the respondents had a significantly negative effect on the aspects of competitive advantages, performance, and sustainability among micro-enterprises in Peninsular Malaysia. Despite of the widely acknowledged and empirically examined effects of socioeconomic antecedents upon micro-enterprise performance, the focus on the effect of a more comprehensive measure of socioeconomic condition, that is, economic vulnerability, among low-income households appears to be scant. Hence, the outcomes of this study are able to provide critical insights for development organizations pertaining to development programs and their effectiveness on economically vulnerable, particularly among low-income households in Peninsular Malaysia.

Since the 1980s, Chinese economy grew rapidly. With the rapid economic growth, Chinese energy consumption sharply increased. The relation between Chinese energy consumption and economic growth is focused on, and many researchers have studied this issue by applying the methods such as granger causality test. However, the results just reveal the relation in a very long period. In this paper, the history of Chinese economy is divided into four periods. And the relation between Chinese energy consumption and economic growth is examined by applying grey incidence analysis, which is one of the most important methods of grey system theory which can be applied to solve the problems with small samples. The results show that the relations in different periods are not the same. The degree of grey incidences between total energy consumption and values added of secondary industry is larger, and the degree of grey incidences between GDP and consumption of coal is larger too. And the policy implications of these results are explained.

Assessment and exploitation of energy-related externalities in the industrial sector

Diakoulaki, D.; Mirasgedis, S.; Tourkolias, C.

2007-01-01

The scope of this paper is to comparatively evaluate the effectiveness of alternative policy measures in reducing impacts from atmospheric pollution generated from industrial energy use. The evaluation procedure relies on the assessment of energy-related externalities by exploiting the methodology developed in the framework of the ExternE project. The analysis focuses on 2 industrial units located in the Greater Athens area and examines three types of abatement measures that can be used independently of the extent energy saving or end-of-pipe emission reduction measures are used: substitution of fuel oil with natural gas, relocation of the units several hundreds of kilometers far from Athens and increase of stack height in the same site. It results that the use of natural gas is by far the most effective among these measures, leading to a reduction of more than 90% of both local and regional damages. The relative effectiveness of the examined measures does not change if the significant uncertainties associated with the accounting procedure are taken into account, while inclusion of the external cost due to greenhouse gases emissions is further accentuating the advantages of natural gas. Moreover, it is shown that the quantifiable energy-related external costs of a single industrial product, may be very low compared to the corresponding private costs, but they sum up to significantly high damages to society if we take into account the total energy consumption in the industrial sector

Electron beam absorption in solid and in water phantoms: depth scaling and energy-range relations

International Nuclear Information System (INIS)

Grosswendt, B.; Roos, M.

1989-01-01

In electron dosimetry energy parameters are used with values evaluated from ranges in water. The electron ranges in water may be deduced from ranges measured in solid phantoms. Several procedures recommended by national and international organisations differ both in the scaling of the ranges and in the energy-range relations for water. Using the Monte Carlo method the application of different procedures for electron energies below 10 MeV is studied for different phantom materials. It is shown that deviations in the range scaling and in the energy-range relations for water may accumulate to give energy errors of several per cent. In consequence energy-range relations are deduced for several solid phantom materials which enable a single-step energy determination. (author)

Wormholes are hypothetical shortcuts in spacetime that in general relativity unavoidably violate all of the pointwise energy conditions. In this paper, we consider several wormhole spacetimes that, as opposed to the standard designer procedure frequently employed in the literature, arise directly from gravitational actions including additional terms resulting from contractions of the Ricci tensor with the metric, and which are formulated assuming independence between metric and connection (Palatini approach). We reinterpret such wormhole solutions under the prism of General Relativity and study the matter sources that thread them. We discuss the size of violation of the energy conditions in different cases and how this is related to the same spacetimes when viewed from the modified gravity side. (orig.)

Primary copper production is a major activity in the mining sector of several countries. However, it is highly energy-intensive and poses important environmental hazards. In the case of Chile, the world's largest copper producer (40% of world total), we examine its energy consumption and energy-related environmental implications over a time horizon of 25 years. Concerning the latter, we focus on greenhouse-gas (GHG) emissions, one of the most debated environmental issues. This paper follows up our previous report in which the current situation was analyzed and a particular technical option for improving the energy efficiency and concurrently reducing GHG emissions was discussed. Estimated reference or base (BS) and mitigation (MS) scenarios are developed for the period ending in 2020. The former assesses the energy demand projected in accordance with production forecasts and specific energy consumption patterns (assuming that energy efficiency measures are adopted 'spontaneously') with their resultant GHG emissions, while the latter assumes induced actions intended to reduce emissions by adopting an aggressive policy of efficient energy use. For the year 2020, the main results are: (i) BS, 1214 t of CO{sub 2}/ton of refined copper content (49% lower than in 1994); (ii) MS, 1037 t of CO{sub 2}/t of refined copper content (56% lower than in 1994). CO{sub 2} emissions have been estimated considering both fuel and electricity process requirements. (author)

Local energy equation for two-electron atoms and relation between kinetic energy and electron densities

International Nuclear Information System (INIS)

March, N.H.

2002-08-01

In early work, Dawson and March [J. Chem. Phys. 81, 5850 (1984)] proposed a local energy method for treating both Hartree-Fock and correlated electron theory. Here, an exactly solvable model two-electron atom with pure harmonic interactions is treated in its ground state in the above context. A functional relation between the kinetic energy density t(r) at the origin r=0 and the electron density p(r) at the same point then emerges. The same approach is applied to the Hookean atom; in which the two electrons repel with Coulombic energy e 2 /r 12 , with r 12 the interelectronic separation, but are still harmonically confined. Again the kinetic energy density t(r) is the focal point, but now generalization away from r=0 is also effected. Finally, brief comments are added about He-like atomic ions in the limit of large atomic number. (author)

Full Text Available España, al igual que Grecia, Portugal o Italia, es hoy en día uno de los países europeos con menos previsiones de crecimiento económico y con más tasa de paro de la Unión Europea. Su tejido empresarial, a diferencia de otros países como los nórdicos o centroeuropeos, viene caracterizado por el protagonismo de empresas de muy reducida dimensión con una media de 1-3 empleados. Estas empresas se caracterizan actualmente por el constante cierre de sus negocios y por la destrucción de empleo. Por este motivo, este trabajo pretende conocer cómo la crisis económica ha afectado a las microempresas y que factores han podido ser determinantes en su gestión. En concreto, se ha estudiado el caso español, extrapolable al resto de países mediterráneos, analizando las variables: formación, experiencia, antigüedad e innovación mediante un estudio empírico. / Spain, as other countries like Greece, Portugal and Italy, is today one of the European countries with less economic growth forecasts and more unemployment of the European Union. Its companies, unlike the Nordic and Central European countries, are characterized by the prominence of small size companies with an average of 1-3 employees. These companies are currently characterized by the continued closure of their business and job losses. For this reason, this work aims to study how the economic crisis has affected micro-enterprises and what factors were decisive in their management. In particular we have studied the Spanish case, extrapolated to other Mediterranean countries, analyzing the variables: training, experience, age firm and innovation through an empirical study.

Availability and quality of water related to western energy

International Nuclear Information System (INIS)

Hudson, H.H.

1981-01-01

Much of the nation's energy resources is contained in seven states of the western United States. Arizona, New Mexico, Colorado, Utah, Wyoming, Montana, and North Dakota contain 40% of the nation's coal and 90% of its uranium and shale oil. Although rich in energy resources, these states are chronically deficient in water. Coal mining and subsequent land reclamation require relatively small amounts of water. Plans that require large quantities of water to transport and convert the coal to energy include the operation of coal-slurry pipelines, thermal-electric power generation, and coal gasification. Production of oil from shale by conventional mining techniques may require about three or four unit volumes of water for each unit volume of shale oil produced. Nearly half of this water would be needed to reestablish vegetation on waste material. In-situ extraction of oil would require substantially less water. Extracting and processing uranium require relatively small amounts of water. There may be problems of the quality of local groundwater where solution mining is practiced and where uranium ore is removed from water-saturated rocks that are then exposed to oxidation. Estimates of amounts of water required to support the development of western energy resources are highly variable and depend on the conversion technology, the level of anticipated development, and the quality of the water required by any given use or process. Conservative estimates exceed 2000 cu hm/year by the year 2000. Although water supplies in the amounts anticipated as being needed for energy development are available within the seven states, their availability locally may depend on satisfying environmental objections, modifying legal and institutional arrangements that presently control water distribution and use, and constructing additional reservoirs and distribution systems

Dispersion and energy conservation relations of surface waves in semi-infinite plasma

International Nuclear Information System (INIS)

Atanassov, V.

1981-01-01

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

The household energy gap: examining the divide between habitual- and purchase-related conservation behaviours

International Nuclear Information System (INIS)

Barr, Stewart; Gilg, A.W.; Ford, Nicholas

2005-01-01

This paper examines the conceptual divide between energy saving behaviours in the home, relating to purchase-oriented behaviours and habitual action to conserve energy. Considerable empirical research indicates that this divide is of utility when characterising energy saving behaviour. However, little attention has been focused around the association between energy saving behaviours and other environmental actions. Accordingly, this paper examines the structural bases of energy conservation behaviours in the wider context of environmental behaviour. These findings are then used to examine the characteristics of energy savers as they relate to other environmental actions. Using cluster analysis, the paper defines a range of behavioural characteristics that transcend energy saving and other environmental actions. The use of such an approach to policy makers seeking to encourage energy conservation practices is discussed at the end of the paper

Proceedings of the 11th forum: Croatian Energy Day: Regulation problems relating to energy service markets

International Nuclear Information System (INIS)

2002-01-01

The main goals of the majority of processes and developments relating to energy sectors of today present the enhancement of energy sector efficiency, ensuring of stable financial sources and safe return of the means invested through practice of activities at the market of energy and energy services, i.e. public services or monopoly. This is to be achieved by means of energy sector restructuring and liberalisation, pluralism of ownership and transparency of the organisational and management scheme. Thereby, an important role and significance for the realisation of these aims, for the development and energy market functioning on the national level, as well as for the achievement of reciprocity and complementarity of national markets with regional and multi-national energy markets, is held by models and forms of energy activity regulation. In a limited sense, the regulation itself should constitute an adequate stimulating framework for free energy flows, transparent and non- discriminating conditions for the utilisation of transmission and transportation systems and networks, protection of supplier choice rights, pluralism of ownership and ownership rights, protection of energy and energy services' quality, environmental protection, protection of purchasers and consumers and protection of energy subjects. For all these reasons, aspects and problems appertaining to energy sector and energy activities' regulation have been chosen as the theme and contents of the 11th Forum. Various countries have undertaken and implemented or are in the process of implementation of different models and contents referring to energy sector and energy activity regulation. Experience and legislative practice are quoted as the main criteria. The aim of this Forum is to set forth and clarify experiences and solutions connected to the regulation of energy activities in numerous European countries or in the world

Shifting policy priorities in EU-China energy relations: Implications for Chinese energy investments in Europe

Gippner, Olivia; Torney, Diarmuid

2017-01-01

Shifting energy policy priorities both in China and the EU (European Union) have transformed their bilateral relationship. In order to assess the impact of domestic policy priorities on bilateral energy cooperation and climate policy, this comparative study traces the evolution of EU and Chinese approaches to energy policy – and their relative emphasis on factors and frames such as availability, efficiency, affordability and environmental stewardship. Drawing on government documents and a data set of interviews with Chinese policy-makers, experts and academics in 2015–2016, the article argues that while the EU started with a strong emphasis on environmental stewardship and moved towards a focus on affordability and availability, China started with a strong emphasis on availability and has moved towards a greater emphasis on environmental stewardship. This shift in frames on the Chinese side and subsequent changes in subsidy structures and targets can partially explain the increase in investments in renewable energy technologies. The article concludes that the Chinese and EU perspectives have become more aligned over the past ten years, coinciding with an increasing trend towards renewable energy in Chinese energy investments in the EU, for example in Italy and the UK. - Highlights: • Compares dominant frames of energy policy in China and the European Union in the period 2005–2015. • Shows that there has been a convergence of policy frames between China and the EU. • Convergence on environmental stewardship is necessary but not sufficient for FDI in clean energy.

Energy saving in Swedish households. The (relative) importance of environmental attitudes

International Nuclear Information System (INIS)

Martinsson, Johan; Lundqvist, Lennart J.; Sundstroem, Aksel

2011-01-01

The objectives for energy saving in the housing sector set by recent Swedish energy and climate policies are quite demanding. This article uses nation-wide Swedish survey data from 2004 to 2007 to explore the potential for achieving those targets. Earlier findings that socio-economic characteristics such as age, housing type and income are strongly linked to higher propensities to save on heating and hot water usage are confirmed by ordered logistic regression models. However, general environmental attitudes are also found to play a crucial role. When assessing the relative importance of socio-economic factors and environmental attitudes, the effect on energy saving is generally greater for the former than the latter. In addition, important interaction effects are identified. In relative terms, the effect of environmental attitudes is clearly stronger among households in apartment blocks than among those in detached housing, and stronger among households with higher income than among those with lower income. We end by discussing the implications for the selection and targeting of policy measures to tap the energy savings potential in the population. - Highlights: → We use Swedish survey data to analyse the determinants of household energy saving. → Housing type plays a crucial role for individuals' propensity to save energy. → Environmental attitudes are clearly more important in high-income households. → Environmental attitudes are clearly more important for people in apartment blocks.

Unraveling the interlayer-related phonon self-energy renormalization in bilayer graphene.

Science.gov (United States)

Araujo, Paulo T; Mafra, Daniela L; Sato, Kentaro; Saito, Riichiro; Kong, Jing; Dresselhaus, Mildred S

2012-01-01

In this letter, we present a step towards understanding the bilayer graphene (2LG) interlayer (IL)-related phonon combination modes and overtones as well as their phonon self-energy renormalizations by using both gate-modulated and laser-energy dependent inelastic scattering spectroscopy. We show that although the IL interactions are weak, their respective phonon renormalization response is significant. Particularly special, the IL interactions are mediated by Van der Waals forces and are fundamental for understanding low-energy phenomena such as transport and infrared optics. Our approach opens up a new route to understanding fundamental properties of IL interactions which can be extended to any graphene-like material, such as MoS₂, WSe₂, oxides and hydroxides. Furthermore, we report a previously elusive crossing between IL-related phonon combination modes in 2LG, which might have important technological applications.

Universal binding energy relation for cleaved and structurally relaxed surfaces

International Nuclear Information System (INIS)

Srirangarajan, Aarti; Datta, Aditi; Gandi, Appala Naidu; Ramamurty, U; Waghmare, U V

2014-01-01

The universal binding energy relation (UBER), derived earlier to describe the cohesion between two rigid atomic planes, does not accurately capture the cohesive properties when the cleaved surfaces are allowed to relax. We suggest a modified functional form of UBER that is analytical and at the same time accurately models the properties of surfaces relaxed during cleavage. We demonstrate the generality as well as the validity of this modified UBER through first-principles density functional theory calculations of cleavage in a number of crystal systems. Our results show that the total energies of all the relaxed surfaces lie on a single (universal) energy surface, that is given by the proposed functional form which contains an additional length-scale associated with structural relaxation. This functional form could be used in modelling the cohesive zones in crack growth simulation studies. We find that the cohesive law (stress–displacement relation) differs significantly in the case where cracked surfaces are allowed to relax, with lower peak stresses occurring at higher displacements.

Ney, R.; Michna, J.; Ekmanis, J.; Zeltins, N.; Zebergs, V.

2008-01-01

Nowadays, the efficiency of energy use in the Central and East-European (CEE) countries is insufficient, being much lower than in the 'Old Europe'. The problem becomes increasingly pressing due to non-stop increasing prices of energy carriers (especially of crude oil). The authors trace the development of research activities in this sphere, classifying the revealed changes in parameters of energy consumption processes in particular time intervals into deterministic, probabilistic, and fuzzy. The paper presents a thorough analysis of decision-making in the energy management at its different levels normative, strategic, and operative. Particular attention is given to the management under uncertainty conditions - i.e. to the risk management. The most wanted research directions in this area proposed by the energy and environment policy (EEP) Center specially created for CEE countries concern management under risk connected with innovations, international activities, loss of reputation, etc.. The authors consider in detail the risk management with insufficient knowledge (non-knowledge) and under chaos. Much consideration is given to the scenario management and the game theory principles as related to the sphere of energy use. (Authors)

The purpose of this research is to clarify the effect of public relations activities in the nuclear energy field and public participation toward the improvement of the risk literacy of nuclear energy. According to the survey results of the actual public relations activities taken by nuclear energy industry, the opportunity for interactive communications between the public and the industry is insufficient. Consequently, we propose building up more opportunities for participation and collaboration of citizens and industries in order to improve interactive communications reflecting public opinions and points of view.

Sudarshan, E. C. G.

1993-01-01

The close relationship between the zero point energy, the uncertainty relations, coherent states, squeezed states, and correlated states for one mode is investigated. This group-theoretic perspective enables the parametrization and identification of their multimode generalization. In particular the generalized Schroedinger-Robertson uncertainty relations are analyzed. An elementary method of determining the canonical structure of the generalized correlated states is presented.

Water-related energy is an inexhaustible and renewable energy resource in our environment, which has huge amount of energy and is not largely dictated by daytime and sunlight. The transparent characteristic plays a key role in practical applications for some devices designed for harvesting water-related energy. In this paper, a highly transparent triboelectric nanogenerator (T-TENG) was designed to harvest the electrostatic energy from flowing water. The instantaneous output power density of the T-TENG is 11.56 mW/m2. Moreover, with the PTFE film acting as an antireflection coating, the maximum transmittance of the fabricated T-TENG is 87.4%, which is larger than that of individual glass substrate. The T-TENG can be integrated with silicon-based solar cell, building glass and car glass, which demonstrates its potential applications for harvesting waste water energy in our living environment and on smart home system and smart car system.

We studied cellular energy allocation (CEA) in three Arctic benthic species (Gammarus setosus (Amphipoda), Onisimus litoralis (Amphipoda), and Liocyma fluctuosa (Bivalvia)) exposed to oil-related compounds. The CEA biomarker measures the energy budget of organisms by biochemically assessing changes in energy available (carbohydrates, protein and lipid content) and the integrated energy consumption (electron transport system activity (ETS) as the cellular aspect of respiration). Energy budget was measured in organisms subjected to water-accommodated fraction (WAF) of crude oil and drill cuttings (DC) to evaluate whether these compounds affect the energy metabolism of the test species. We observed significantly lower CEA values and higher ETS activity in G. setosus subjected to WAF treatment compared to controls (p {<=} 0.03). Higher CEA value and lower cellular respiration were observed in O. litoralis exposed to DC compared to controls (p = 0.02). No difference in the energy budget of L. fluctuosa was observed between the treatments (p {>=} 0.19). Different responses to oil-related compounds between the three test species are likely the result of differences in feeding and burrowing behavior and species-specific sensitivity to petroleum-related compounds.

Relativistic gravitational potential and its relation to mass-energy

International Nuclear Information System (INIS)

Voracek, P.

1979-01-01

From the general theory of relativity a relation is deduced between the mass of a particle and the gravitational field at the position of the particle. For this purpose the fall of a particle of negligible mass in the gravitational field of a massive body is used. After establishing the relativistic potential and its relationship to the rest mass of the particle, we show, assuming conservation of mass-energy, that the difference between two potential-levels depends upon the value of the radial metric coefficient at the position of an observer. Further, it is proved that the relativistic potential is compatible with the general concept of the potential also from the standpoint of kinematics. In the third section it is shown that, although the mass-energy of a body is a function of the distance from it, this does not influence the relativistic potential of the body itself. From this conclusion it follows that the mass-energy of a particle in a gravitational field is anisotropic; isotropic is the mass only. Further, the possibility of an incidental feed-back between two masses is ruled out, and the law of the composition of the relativistic gravitational potentials is deduced. Finally, it is shown, by means of a simple model, that local inhomogeneities in the ideal fluid filling the Universe have negligible influence on the total potential in large regions. (orig.)

OAK-B135 Minority Undergraduate Training for Energy-Related Careers (MUTEC). First, all the co-investigators would like to thank the Department of Energy's Minority Impact Office for awarding FIU with the MUTEC grant for the past five years. We believe it has made a difference, especially in the creation of a new, streamlined curriculum that began with the Mechanical Engineering Program and has now become college wide. Second, we have given 774 students an introduction to engineering, something that did not exist 3 years ago. Third, we have given FLAME the opportunity to participate in this program through the equivalent introduction to engineering course. Over 150 of those students have participated and have a 100% record of completing the program once, they start. Over 80% of those students have gone on to college. Fourth, we have aided 32 undergraduates continue in their engineering studies. Of those half have already graduated, and half of those have gone on to graduate school. One of these graduate school students has graduated with an MSME and another has won an NSF Scholarship. Fifth, we have created a bank of 51 2-hour tapes in 10 science and engineering science areas and covered the spectrum of math courses from geometry/trigonometry to differential equations. Sixth, we have created two examinations for use in preparation for entry into the engineering programs and in preparation for the EIT. Seventh, we have created a streamlined curriculum and four options, two of which are energy related. From these points, we believe that the program was very successful and for that we wish to thank the Department of Energy and specifically Ms. Estela Romo for her unwavering support

Renewable energy partnerships in development cooperation: Towards a relational understanding of technical assistance

International Nuclear Information System (INIS)

Kruckenberg, Lena J.

2015-01-01

Recent decades have witnessed a surge in international programmes established to assist the adoption of renewable energy technologies (RETs) in low and lower-middle income countries. So far, such programmes have yielded mixed success. While partnerships between international, national and local organisations have become the pre-eminent model for RET programmes, we know relatively little about their contribution. This article traces the role of renewable energy partnerships in development cooperation, shifting the analytical emphasis from barriers and drivers to key actors and their relationships. It presents a relational approach for the analysis of development assistance for renewable energy, drawing on theories concerning the role of strong and weak ties in inter-organisational networks. Through an analysis of seven empirical cases from Central America, the article provides insights into how different forms of inter-organisational relationships can facilitate implementation of RET programmes but do not necessarily enhance the capacities of local organisations in a way to support a more sustainable adoption of RETs. On the basis of this analysis, theoretical and policy implications are given concerning the potential of relational approaches for researching technology diffusion processes, and the role of strong and weak ties for the success – or failure – of renewable energy partnerships. - Highlights: • Study of renewable energy partnerships in development cooperation. • Relational framework for analysis of inter-organisational technology diffusion. • Empirical cases of renewable energy partnerships in Central America. • Different types of network relationships enable/inhibit sustainable adoption. • Three policy recommendations for programme development

Water related planning and design at energy firms are examined. By identifying production alternatives and specifying the cost of these alternatives under a variety of conditions, one gains insight into the future pattern of water use in the energy industry and the response of industry to water-related regulation. In Part II, the three principal decisions of industry that affect water allocation are reviewed: where to build plants, where to get water, and how much water to use. The cost of water use alternatives is reviewed. Part III presents empirical data to substantiate the inferences derived from engineering/economic analysis. The source of water, type of cooling system, and pattern of discharge for electric plants constructed during the 1970s or projected to come on line in this decade are reported. In the 1970s in the US, there was a trend away from once-through cooling toward use of evaporative cooling. Freshwater, as a source of supply, and discharge of effluent were standard practice. In the 1980s, almost all new capacity in the states and basins surveyed will use evaporative cooling. It is pointed out that a thorough understanding of industrial water use economics and water markets is a precursor to successful regulation

French energy research problems in relation to national energy goals

Ferrari, A.

1984-01-01

There is a new view in energy planning: the new Government has firmly decided to enlarge the spectrum of energy technologies, to give more possibilities. Some new technologies if they reach a sufficient economic balance may be better than the ones used presently, and strict economic analysis shall be complemented by including external cost and taking into account the other considerations (political, social, etc.). The energy situation is serious and no technology should be dismissed: nuclear energy which with coal is one of the two sources of energy already abundant, cannot be discarded especially in a country like France, poor in fossil sources. France shall go on using nuclear energy and this means pursuing the development of the Fast Breeder Reactor Technology, because this is a unique insurance against possible future energy scarcity. Under strict nonproliferation conditions they shall also continue the effort to export nuclear units, using the expertise gained while implementing their own program

This paper explains new energy development in New Zealand and Australia. New Zealand produces only 40% of its liquid fuel requirements but is self sufficient in its electricity produced by hydro power and geothermal power. However, the long term outlook is far from healthy due to increasing demand for electricity, depletion of oil and natural gas, and movement against environmental issues relating to the development of hydro and geothermal resources. The government has recognized the need to promote energy efficiency and conservation, and to develop renewable energy resources. However, the total funds allocated are small. The Australian economy has been maintained primarily by exports of coal, minerals and agricultural products. The government has basically deregulated the economy but still plays an important part in determining the direction and allocating funds for R and D in all sectors including energy. Australia is self sufficient in all energies other than oil; hence, there is little incentive in developing alternative fuels. However, there has been an increased interest in new energy technologies stimulated by such issues as global warming gases and exports of energy technology to Asia. (NEDO)

Full Text Available This manuscript develops a logarithmic mean Divisia index I (LMDI decomposition method based on energy and CO2 allocation Sankey diagrams to analyze the contributions of various influencing factors to the growth of energy-related CO2 emissions on a national level. Compared with previous methods, we can further consider the influences of energy supply efficiency. Two key parameters, the primary energy quantity converted factor (KPEQ and the primary carbon dioxide emission factor (KC, were introduced to calculate the equilibrium data for the whole process of energy unitization and related CO2 emissions. The data were used to map energy and CO2 allocation Sankey diagrams. Based on these parameters, we built an LMDI method with a higher technical resolution and applied it to decompose the growth of energy-related CO2 emissions in China from 2004 to 2014. The results indicate that GDP growth per capita is the main factor driving the growth of CO2 emissions while the reduction of energy intensity, the improvement of energy supply efficiency, and the introduction of non-fossil fuels in heat and electricity generation slowed the growth of CO2 emissions.

Most individual processes relating water and energy interdependence have been assessed in many different ways over the last decade. It is time to step up and include the results of these studies in management by proportionating a tool for integrating these processes in decision-making to effectively understand the tradeoffs between water and energy from management options and scenarios. A simple but powerful decision support system (DSS) for water management is described that includes water-related energy use and GHG emissions not solely from the water operations, but also from final water end uses, including demands from cities, agriculture, environment and the energy sector. Because one of the main drivers of energy use and GHG emissions is water pumping from aquifers, the DSS combines a surface water management model with a simple groundwater model, accounting for their interrelationships. The model also explicitly includes economic data to optimize water use across sectors during shortages and calculate return flows from different uses. Capabilities of the DSS are demonstrated on a case study over California's intertied water system. Results show that urban end uses account for most GHG emissions of the entire water cycle, but large water conveyance produces significant peaks over the summer season. Also the development of more efficient water application on the agricultural sector has increased the total energy consumption and the net water use in the basins.

Partsch, Christoph

2014-04-01

Bilateral relations between Germany and Algeria are officially described, by both sides, as good and friendly. Nevertheless, in Germany, errors in assessment of the 'Arab spring' led to a lack of interest in Algeria, and still affect German foreign policy. Furthermore, the lack of reform in Algeria isolates the country both politically and economically, while it looks as if the evolution of the world energy market will be decisive for its development. The two countries have under-exploited, even totally neglected, the possibilities for cooperation on the energy market. Algeria may currently be one of the most stable countries in North Africa, but it will undergo some turmoil within the next fifteen years. This perspective should provoke a stronger response from the whole of Europe, and Germany in particular, leading it to engage more with the biggest African country, and still the richest one.

In recent years, due to concerns over national security from both economic and military standpoints, increased attention has been given to the production of renewable energy in order to reduce American dependence on foreign supplies of energy. These concerns, along with those related to the effect of fossil fuels on the environment, have served to heighten the enthusiasm for finding replacements for traditional energy sources, along with helping to highlight the need for energy efficiency in American homes and businesses. Throughout the nation, this has been exemplified in an increased entrepreneurial activity to produce liquid fuels, thermal energy and electricity from a vast range of sources such as plants, trees, bacteria, the sun, wind, waves and the Earth itself. Coupled with tax subsidies, loan guarantees, renewable fuel standards, and various other government incentives and legislative encouragements we have seen a big jump in the production of renewable energy in the United States in the last ten years. But we are just getting started!

Grey relation performance correlations among economics, energy use and carbon dioxide emission in Taiwan

Lin, Sue J.; Lu, I.J.; Lewis, Charles

2007-01-01

This study explores the inter-relationships among economy, energy and CO 2 emissions of 37 industrial sectors in Taiwan in order to provide insight regarding sustainable development policy making. Grey relation analysis was used to analyse the productivity, aggregate energy consumption, and the use of fuel mix (electricity, coal, oil and gas) in relation to CO 2 emission changes. An innovative evaluative index system was devised to explore grey relation grades among economics, energy and environmental quality. Results indicate that a rapid increase in electricity generation during the past 10 years is the main reason for CO 2 emission increase in Taiwan. The largest CO 2 emitting sectors include iron and steel, transportation, petrochemical materials, commerce and other services. Therefore, it is important to reduce the energy intensity of these sectors by energy conservation, efficiency improvement and adjustment of industrial structure towards high value-added products and services. Economic growth for all industries has a more significant influence, than does total energy consumption, on CO 2 emission increase in Taiwan. It is also important to decouple the energy consumption and production to reduce the impacts of CO 2 on economic growth. Furthermore, most of the sectors examined had increased CO 2 emissions, except for machinery and road transportation. For high energy intensive and CO 2 intensive industries, governmental policies for CO 2 mitigation should be directed towards low carbon fuels as well as towards enhancement of the demand side management mechanism, without loss of the nation's competitiveness

Highlights: •This study quantifies the nexus as energy intensity and greenhouse gas potential. •Baseline water stress and return flow ratio are identified as water risks. •Source water accessibility significantly contributes to variations in the nexus. •Water risks have little impact on the nexus of wastewater systems. •Study on the nexus is suggested to be conducted at regional levels. -- Abstract: The importance of the interdependence between water and energy, also known as the water-energy nexus, is well recognized. The water-energy nexus is typically characterized in resource use efficiency terms such as energy intensity. This study aims to explore the quantitative results of the nexus in terms of energy intensity and environmental impacts (mainly greenhouse gas emissions) on existing water systems within urban water cycles. We also characterized the influence of water risks on the water-energy nexus, including baseline water stress (a water quantity indicator) and return flow ratio (a water quality indicator). For the 20 regions and 4 countries surveyed (including regions with low to extremely high water risks that are geographically located in Africa, Australia, Asia, Europe, and North America), their energy intensities were positively related to the water risks. Regions with higher water risks were observed to have relatively higher energy and GHG intensities associated with their water supply systems. This mainly reflected the major influence of source water accessibility on the nexus, particularly for regions requiring energy-intensive imported or groundwater supplies, or desalination. Regions that use tertiary treatment (for water reclamation or environmental protection) for their wastewater treatment systems also had relatively higher energy and GHG emission intensities, but the intensities seemed to be independent from the water risks. On-site energy recovery (e.g., biogas or waste heat) in the wastewater treatment systems offered a great

Concepts for dynamic modelling of energy-related flows in manufacturing

International Nuclear Information System (INIS)

Wright, A.J.; Oates, M.R.; Greenough, R.

2013-01-01

Highlights: ► Modelling of the thermal flows in factories and processes is usually separate. ► We propose a set of key features for an integrated thermal model. ► Such models can be used to improve the efficiency of manufacturing processes. - Abstract: Industry uses around one third of the world’s energy, and accounts for about 40% of global carbon dioxide emissions. There is increasing economic and social pressure to improve efficiency and create closed-loop industrial systems, in which energy efficiency plays a key role. This paper describes some of the key concepts involved in modelling the energy flows in manufacturing, both for the building services and the industrial processes. Detailed dynamic energy simulation of buildings is well established and routinely used, working on a time series basis – but current tools are inadequate to model the energy flows of many industrial processes. There are also well-established models of manufacturing flows, used to optimise production efficiency, but typically not modelling energy, and usually representing production and material flows as event-driven processes. The THERM project has developed new software tools to model energy-related and other utility flows in manufacturing, incorporating these into existing thermal models of factory buildings. This makes it possible to map out the whole energy system, and hence to test efficiency measures, to understand the effect of processes on building energy use, to investigate recycling of heat or cooling into other processes or building conditioning, and so on. The paper describes some of the key concepts and modelling approaches involved in developing these models, and gives examples of some real processes modelled in factories. It concludes that such models are entirely feasible and potentially very useful, although to develop a tool which comprehensively models both energy and manufacturing flows would be a major undertaking

The relative importance of physical and biological energy in landscape evolution

Science.gov (United States)

Turowski, J. M.; Schwanghart, W.

2017-12-01

Landscapes are formed by the interplay of uplift and geomorphic processes, including interacting and competing physical and biological processes. For example, roots re-inforce soil and thereby stabilize hillslopes and the canopy cover of the forest may mediate the impact of precipitation. Furthermore, plants and animals act as geomorphic agents, directly altering landscape response and dynamics by their actions: tree roots may crack rocks, thus changing subsurface water flows and exposing fresh material for denudation; fungi excrete acids that accelerate rates of chemical weathering, and burrowing animals displace soil and rocks while digging holes for shelter or in search of food. Energetically, landscapes can be viewed as open systems in which topography stores potential energy above a base level. Tectonic processes add energy to the system by uplift and mechanically altering rock properties. Especially in unvegetated regions, erosion and transport by wind can be an important geomorphic process. Advection of atmospheric moisture in high altitudes provides potential energy that is converted by water fluxes through catchments. At the same time, the conversion of solar energy through atmospheric and biological processes drives primary production of living organisms. If we accept that biota influence geomorphic processes, then what is their energetic contribution to landscape evolution relative to physical processes? Using two case studies, we demonstrate that all components of energy input are negligible apart from biological production, quantified by net primary productivity (NPP) and potential energy conversion by water that is placed high up in the landscape as rainfall and leaves it as runoff. Assuming that the former is representative for biological energy and the latter for physical energy, we propose that the ratio of these two values can be used as a proxy for the relative importance of biological and physical processes in landscape evolution.

McComas, Katherine A.; Lu, Hang; Keranen, Katie M.; Furtney, Maria A.; Song, Hwansuck

2016-01-01

Growing awareness of the potential for some energy-related activities to induce earthquakes has created a need to understand how the public evaluates the risks of induced earthquakes versus the benefits of energy development. To address this need, this study presents a web survey that used a between-subjects factorial experimental design to explore the views of 325 U.S. adults, who were asked about their experiences with earthquakes; risk perceptions related to different causes of earthquakes (e.g., natural versus induced); and acceptability of earthquakes depending on the benefits, beneficiaries, and decision making process. The results found that participants had more negative feelings toward induced versus naturally occurring earthquakes. Although they judged no earthquake as “acceptable,” participants rated induced earthquakes significantly less acceptable than naturally occurring ones. Attributing the benefits to the provision of renewable energy or climate change mitigation did not increase induced earthquake acceptability, and no particular beneficiary made earthquakes more acceptable, although private companies as beneficiaries made earthquakes less acceptable. Finally, induced earthquake acceptability was significantly higher when people believed that people like them had a voice in the decision to implement the technology that caused the earthquake, underscoring the importance of public engagement in the development of energy technologies. - Highlights: • Human induced earthquakes were perceived as more negative than natural earthquakes. • Attributing benefits to renewable energy did not increase earthquake acceptability. • Acceptability was highest after a procedurally fair decision making process. • Acceptability was lowest following an expert-driven decision.

According to the author, the intended German energy turnaround cannot be achieved solely on the basis of power from renewables and by constructing new passive buildings. Also required are decentral energy services if the energy saving and efficiency goals are to be achieved. In spite of many variations, the basic structure of these is the following: A contractor providing energy services does not only supply energy but also carries the risk and responsibility for efficient supply. This will relieve energy users, whether industrial or trade enterprises, public administration or home owners from this task; also, this integrated approach will open up undeveloped efficiency potentials. The book discusses current legal issues in a clear and practice-oriented manner and also provides a check list for energy contracting and an exemplary contract. (orig./RHM)

Sectoral analysis of energy consumption and energy related CO2 emissions in Finland 1990-1999

International Nuclear Information System (INIS)

Kirjavainen, M.; Tamminen, E.

2002-03-01

This study describes the development of energy consumption and energy related CO 2 emissions in Finland between 1990-1999. For better understanding of the factors behind the development in main sectors, special indicators are calculated to evaluate how the overall development of the sector is affected by the general activity of the sector, changes in sectoral structure and changes in end-use intensities within the sector. The specific energy consumption of space heating reduced especially during the first half of the decade. Also the total CO 2 emissions caused by space heating reduced, in spite of the increase in the building stock. The main reason for this has been the reduction in specific CO 2 emissions in production of district heat. Regardless of the increased traffic and slightly increased use of passenger cars over public transport, the total energy consumption as well as total CO 2 emissions in passenger transport reduced during the decade. The main reason for this is that the specific fuel consumption of passenger cars has reduced significantly. Volumes in freight traffic increased rapidly after the recession, and as no significant changes have occurred in either specific consumptions or in shares of different transport modes, the total energy use as well as total CO 2 emissions of freight transport have increased. The major factors affecting the energy use and CO 2 emissions of the manufacturing sector have been changes in production volumes. After the recession, growth has been rapid and that has resulted in increased total energy use and CO 2 emissions. Anyway, the especially rapid growth of the less energy intensive electronics industry has resulted in downward overall energy intensity within manufacturing sector. Major factors affecting the specific CO 2 emissions in energy production have been changes in the primary energy supply mix. In electricity production, the major factors have been the increase in nuclear capacity and the variation in net

A Comparison of Kinetic Energy and Momentum in Special Relativity and Classical Mechanics

Kinetic energy and momentum are indispensable dynamical quantities in both the special theory of relativity and in classical mechanics. Although momentum and kinetic energy are central to understanding dynamics, the differences between their relativistic and classical notions have not always received adequate treatment in undergraduate teaching.…

Testing Special Relativity at High Energies with Astrophysical Sources

Science.gov (United States)

Stecker, F. W.

2007-01-01

Since the group of Lorentz boosts is unbounded, there is a question as to whether Lorentz invariance (LI) holds to infinitely short distances. However, special and general relativity may break down at the Planck scale. Various quantum gravity scenarios such as loop quantum gravity, as well as some forms of string theory and extra dimension models may imply Lorentz violation (LV) at ultrahigh energies. The Gamma-Ray Large Area Space Telescope (GLAST), to be launched in mid-December, will measure the spectra of distant extragalactic sources of high energy gamma-rays, particularly active galactic nuclei and gamma-ray bursts. GLAST can look for energy-dependent gamma-ray propagation effects from such sources as a signal of Lorentz invariance violation. These sources may also exhibit the high energy cutoffs predicted to be the result of intergalactic annihilation interactions with low energy photons having a flux level as determined by various astronomical observations. With LV the threshold for such interactions can be significantly raised, changing the predicted absorption turnover in the observed spectrum of the sources. Stecker and Glashow have shown that the existence such absorption features in the spectra of extragalactic sources puts constraints on LV. Such constraints have important implications for some quantum gravity and large extra dimension models. Future spaceborne detectors dedicated to measuring gamma-ray polarization can look for birefringence effects as a possible signal of loop quantum gravity. A very small LV may also result in the modification or elimination of the GZK effect, thus modifying the spectrum of ultrahigh energy cosmic rays. This possibility can be explored with ground-based arrays such as Auger or with a space based detector system such as the proposed OWL satellite mission.

Energy levels of one-dimensional systems satisfying the minimal length uncertainty relation

The standard approach to calculating the energy levels for quantum systems satisfying the minimal length uncertainty relation is to solve an eigenvalue problem involving a fourth- or higher-order differential equation in quasiposition space. It is shown that the problem can be reformulated so that the energy levels of these systems can be obtained by solving only a second-order quasiposition eigenvalue equation. Through this formulation the energy levels are calculated for the following potentials: particle in a box, harmonic oscillator, Pöschl–Teller well, Gaussian well, and double-Gaussian well. For the particle in a box, the second-order quasiposition eigenvalue equation is a second-order differential equation with constant coefficients. For the harmonic oscillator, Pöschl–Teller well, Gaussian well, and double-Gaussian well, a method that involves using Wronskians has been used to solve the second-order quasiposition eigenvalue equation. It is observed for all of these quantum systems that the introduction of a nonzero minimal length uncertainty induces a positive shift in the energy levels. It is shown that the calculation of energy levels in systems satisfying the minimal length uncertainty relation is not limited to a small number of problems like particle in a box and the harmonic oscillator but can be extended to a wider class of problems involving potentials such as the Pöschl–Teller and Gaussian wells.

In recent years, pressures on global environment and energy security have led to an increasing demand on renewable energy sources, and diversification of world's energy supply. Among these resources the forest biomass could exert an important role, since it is considered a renewable and CO{sub 2} neutral energy resource, and can potentially provide energy for heat, power and transport fuels. In this study were presented the results of the amounts of forest biomass residues (FBR) available in Portugal, taking into account some conditioning related with land characteristics (e.g. slope). Comparing the FBR consumption for industrial thermal power plants it is possible to verify that the FBR available (1.91x10{sup 6} ton (dry) year{sup -}1) in Portugal is enough to address the needs of industrial plants, but if the planned plants come into operation, the FBR available is no longer sufficient. The operations associated with the FBR harvesting were described, emphasizing the transport between the production locations and the industrial thermal plants. By applying a TRaffic Emission Model (TREM), it was estimated the fuel consumption and related gaseous emissions (CO, CO{sub 2}, PM, NO{sub x}, SO{sub 2}, VOC, CH{sub 4}, NH{sub 3} and N{sub 2}O) associated with the transport of the FBR.

Event-related stresses in energy systems and their effects on energy security

International Nuclear Information System (INIS)

Hughes, Larry; Ranjan, Ashish

2013-01-01

Energy systems change over time as events, such as grid failures, new energy sources, and extreme weather conditions, occur, often affecting the system's energy security. Understanding events, their causes, and how they are handled, can help a jurisdiction and its energy stakeholders develop better, evidence-based energy policy. This paper employs a definition of stress in combination with systems analysis to specify methods for explaining the states through which an energy process, chain, or system passes in response to an event and how this response results in energy security improving, deteriorating, or being maintained. The definition uses three dimensions-availability, affordability, and acceptability-derived from the International Energy Agency's definition of energy security to show when and how a system's energy security will change. Examples are used to illustrate the application of the methods. - Highlights: • A generic set of methods and a common terminology to formalize the ongoing energy security discourse is proposed. • The methods define, measure and explain how energy security can change when events cause stresses in an energy system. • Events are classified in terms of three dimensions derived from the IEA's definition of energy security. • The application of the method is illustrated with detailed examples

Ministry of Economy in co-operation with the Ministry of Education and Sport, Croatian Electric Utility and Enconet International during the year 2002 realized the project of preparing the calendar for 2003 containing primary school pupils' paintings about energy and environment and additional information about preparedness in the Republic of Croatia in the case of nuclear accident and recommendations for acting. The calendar is primarily created for families living in the circle 25 km from the Nuclear Power Plant Krsko and will be distributed to all pupils of primary schools on that territory. Therefore the collecting of paintings was carried out between pupils from fifth to eight grades in those schools. Expert commission chose twelve best paintings from fifty-two collected and ceremonial promotion of the calendar was held in the Technical museum in Zagreb. This kind of project is only one example of public relations with the purpose of knowledge building about successful living together with energy technologies. In this text the course of the project of realizing the calendar will be presented with the special accent on content and purpose of the text about preparedness in the Republic of Croatia in the case of nuclear accident and recommendations for acting.

Ion, R.

1995-01-01

The artificial intelligence (AI) (including Expert Systems (ES), its most important branch) could have a certain place in the future developing of nuclear energy with impact on decision aids techniques and support systems, especially for nuclear safety and radiation protection area. First steps -some based on the Canadian experience - were already done in Romania, in developing AI techniques related to nuclear energy. Newcomers are recommended to start with modest and isolate problems in order to build up the necessary hand-on experience. The moment of the large scale AI implementation in the nuclear energy field will be decided by the balance between conventional computing and Ai computing and also between the advantages and disadvantages of AI. In this frame, the opportunity for research developing and using AI in the nuclear energy field is inherent and must be sustained by the research, design and plant operation authorities and also by the high education universities which are recommended to focus their interest towards the AI field for the next specialists in nuclear energy.

Bartiaux, Françoise; Schmidt, Luísa; Horta, Ana; Correia, Augusta

2016-01-01

The social-class dimension of energy consumption has been rather neglected relative to other theoretical approaches to energy use, despite its potential deployment in energy policies. This paper aims at investigating energy policy-related inequalities across social classes with respect to three dimensions highlighted by environmental-justice theories: income distribution, procedures producing unequal distributional outcomes, and cultural and political recognition of vulnerable and marginalised social groups. These inequalities can be exacerbated or reduced by social diffusion processes, both vertical and horizontal. These processes include policy instruments intending to lower energy consumption in the residential sector. To empirically ground the analysis, two countries with contrasting patterns of income inequalities, Portugal and Belgium, are compared on the basis of qualitative data collected in 2009–2011. We discuss the relevance of integrating the social diffusion dimension in energy policies and propose several policy instruments to do so. One of our main contribution is to argue that both vertical and horizontal diffusion across social classes, if adequately translated into policy instruments, can boost the uptake of residential energy retrofits and other energy saving practices.

Full Text Available Abstract Background Insight in parental energy balance-related behaviours, their determinants and parenting practices are important to inform childhood obesity prevention. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed. The objective of the current study was to examine the test-retest reliability and construct validity of the parent questionnaire used in the ENERGY-project, assessing parental energy balance-related behaviours, their determinants, and parenting practices among parents of 10–12 year old children. Findings We collected data among parents (n = 316 in the test-retest reliability study; n = 109 in the construct validity study of 10–12 year-old children in six European countries, i.e. Belgium, Greece, Hungary, the Netherlands, Norway, and Spain. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC and percentage agreement comparing scores from two measurements, administered one week apart. To assess construct validity, the agreement between questionnaire responses and a subsequent interview was assessed using ICC and percentage agreement. All but one item showed good to excellent test-retest reliability as indicated by ICCs > .60 or percentage agreement ≥ 75%. Construct validity appeared to be good to excellent for 92 out of 121 items, as indicated by ICCs > .60 or percentage agreement ≥ 75%. From the other 29 items, construct validity was moderate for 24 and poor for 5 items. Conclusions The reliability and construct validity of the items of the ENERGY-parent questionnaire on multiple energy balance-related behaviours, their potential determinants, and parenting practices appears to be good. Based on the results of the validity study, we strongly recommend adapting parts of the ENERGY-parent questionnaire if used in future research.

Benzy, V K; Jasmin, E A; Koshy, Rachel Cherian; Amal, Frank; Indiradevi, K P

2018-01-01

The advancement in medical research and intelligent modeling techniques has lead to the developments in anaesthesia management. The present study is targeted to estimate the depth of anaesthesia using cognitive signal processing and intelligent modeling techniques. The neurophysiological signal that reflects cognitive state of anaesthetic drugs is the electroencephalogram signal. The information available on electroencephalogram signals during anaesthesia are drawn by extracting relative wave energy features from the anaesthetic electroencephalogram signals. Discrete wavelet transform is used to decomposes the electroencephalogram signals into four levels and then relative wave energy is computed from approximate and detail coefficients of sub-band signals. Relative wave energy is extracted to find out the degree of importance of different electroencephalogram frequency bands associated with different anaesthetic phases awake, induction, maintenance and recovery. The Kruskal-Wallis statistical test is applied on the relative wave energy features to check the discriminating capability of relative wave energy features as awake, light anaesthesia, moderate anaesthesia and deep anaesthesia. A novel depth of anaesthesia index is generated by implementing a Adaptive neuro-fuzzy inference system based fuzzy c-means clustering algorithm which uses relative wave energy features as inputs. Finally, the generated depth of anaesthesia index is compared with a commercially available depth of anaesthesia monitor Bispectral index.

1983-09-01

The Energy-Related Inventions Program (ERIP) is jointly administered by the US Departments of Energy and Commerce. Grants were awarded for 165 of 208 inventions recommended by the National Bureau of Standards (NBS). Of the 165 inventions, 46 have been able to acquire follow-on financing from a variety of sources. Further, 35 of the inventions have reached the marketplace, and their cumulative sales to date total $178 million. An additional 10 inventions are now starting into production. Jobs that have been created directly by production related to the inventions total 756; additional spin-off jobs attributable to the inventions include component and material suppliers, jobbers, franchisees, and distributors. The program was recently evaluated at Oak Ridge National Laboratory, with the following conclusions: (1) the evaluation process at NBS has been successful in identifying technically and economically feasible inventions, (2) the success rate for the program is about equivalent to the reported success rates of private venture capital firms, (3) the program is supporting inventions at a point in their development where they are supported by neither the venture capital community nor industry, and (4) the one-time DOE grants and the associated ERIP support to inventors have been successful in readying inventors for follow-on financing from the private sector.

Climate Regulation of Rearing-Related Buildings - Evaluating the Factors Related to the Energy Requirement of Heating/Cooling, and Analysis of Alternative Solutions

Directory of Open Access Journals (Sweden)

Toth Laszló

2017-10-01

Full Text Available The most notable role in the energy usage of rearing-related buildings belongs to barn climate. For animals, one of the most important climate parameter is the temperature of the barn atmosphere. This can be kept in the proper interval by either heating or cooling. Apart from the operation of technological solutions, the need for airing barns must be taken into consideration. This means there are special technical requirements for airing. Also, they can cause significant energy losses. The temperature limit of heating is mainly influenced by the technological temperature related to keeping the animal in question, its acceptable differences, the heat loss of the barn, and the airing requirement. Energy sources applicable to heating can be traditional sources (coal, oil, gas, renewable sources (solar, biomass, wind, water, or geothermal energy, or transformed energy (electricity. As these have specific operation systems, they also mean further challenges in implementing efficient energy usage. The usage of heating energy can either be optimised by the rational usage of the heating system, or machinery explicitly made for reserving energy. Sparing heating energy via recuperative heating exchange may cut costs significantly, which we also proved in this research with actual calculations. However, we have to state that the efficient usage of heat exchangers requires that the internal and external temperatures differ greatly, which has a huge impact on heat recovery performance.

2016-05-20

To meet the ever-increasing requirements for the next generation of sustainable and versatile energy-related devices, conjugated polymers, which have potential advantages over small molecules and inorganic materials, are among the most promising types of green candidates. The properties of conjugated polymers can be tuned through modification of the structure and incorporation of different functional moieties. In addition, superior performances can be achieved as a result of the advantages of nanostructures, such as their large surface areas and the shortened pathways for charge transfer. Therefore, nanostructured conjugated polymers with different properties can be obtained to be applied in different energy-related organic devices. This review focuses on the application and performance of the recently reported nanostructured conjugated polymers for high-performance devices, including rechargeable lithium batteries, microbial fuel cells (MFCs), thermoelectric generators, and photocatalytic systems. The design strategies, reaction mechanisms, advantages, and limitations of nanostructured conjugated polymers are further discussed in each section. Finally, possible routes to improve the performances of the current systems are also included in the conclusion. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Yoon, Seok; Buckworth, Janet; Focht, Brian; Ko, Bomna

2013-12-01

This study used a path analysis approach to examine the relationship between feelings of energy, exercise-related self-efficacy beliefs, and exercise participation. A cross-sectional mailing survey design was used to measure feelings of physical and mental energy, task and scheduling self-efficacy beliefs, and voluntary moderate and vigorous exercise participation in 368 healthy, full-time undergraduate students (mean age = 21.43 ± 2.32 years). The path analysis revealed that the hypothesized path model had a strong fit to the study data. The path model showed that feelings of physical energy had significant direct effects on task and scheduling self-efficacy beliefs as well as exercise behaviors. In addition, scheduling self-efficacy had direct effects on moderate and vigorous exercise participation. However, there was no significant direct relationship between task self-efficacy and exercise participation. The path model also revealed that scheduling self-efficacy partially mediated the relationship between feelings of physical energy and exercise participation.

Nuclear energy: strategy of public relations

International Nuclear Information System (INIS)

Timell, S.

1981-01-01

A referendum was held in Sweden on 23rd March 1980, stimulated by the Three Mile Island accident in USA, to determine the future nuclear power development policy. The electricity supply background is that in 1980, 65% of power was hydro, 25% nuclear and 10% coal and oil. In terms of total power consumption, the country is heavily dependent on oil, which represents about 75%. The intensive public relations activity previous to the referendum is described, and this involved fact accumulation and assimilation, dissemination through various media, including brochures, displays, films and leaflets. In the political arena three lines developed: (1) (Conservatives); continue nuclear power, building at least 12 reactors, (2) (Social democrats and liberals); similar to (1), but more cautious, with emphasis on energy conservation, (3) (Centre parties and communists); no more nuclear power, and prevention of uranium extraction in Sweden. The voting was (1) 18.9%, (2) 39.1%, (3) 38.7%, (No decision) 3.3%. (G.C.)

Energy consumption and energy prices

International Nuclear Information System (INIS)

Bentzen, J.

1993-01-01

Data are presented on energy consumption and energy prices related to a number of OECD (Organisation for Economic Co-operation and Development) lands covering the period 1951-1990. The information sources are described and the development of energy consumption and prices in Denmark are illustrated in relation to these other countries. The energy intensity (the relation between energy consumption and the gross national product) is dealt with. Here it is possible to follow development during the whole post-war period. It is generally understood that Denmark saved large amounts of energy after 1973-74 but, taken over the whole post-war period, savings and decline in energy-gross national product relations are less dramatic compared to conditions in other OECD countries. Energy coefficients or elasticities show the relative rise in consumption compared to the relative rise in gross national product (growth rate). This is shown to be typically unstable and an eventual connection with the amount of energy price increase and/or the growth rate of the national economy is considered. Results of Granger causuality tests on energy consumption, national income and energy prices are presented. Effective energy prices were very low in Denmark up to 1970 when they suddenly began to increase. Since the oil crisis Denmark's energy consumption has fallen whereas the other countries have used rather more energy than before. Effective promotion of energy savings must be seen in relation to the fact that the 1970 basis level of energy consumption and intensity was unusually high. The high effective energy prices have also encouraged energy savings in Denmark. (AB)

1979-01-01

In the relativity theory, the variation of a certain amount of energy supplied to a body, according to its speed, has been a matter of controversy. We study this variation either for a fluid that is submitted by a compression, or for a gas receiving heat from outward. It is shown that the problem is solved by a simple matter of definition of the energy received in the system of coordinate where the body is moving. Besides, we establish the impulse-energy tensor for a compressible fluid [fr

Energy demand and energy-related CO2 emissions in Greek manufacturing. Assessing the impact of a carbon tax

International Nuclear Information System (INIS)

Floros, Nikolaos; Vlachou, Andriana

2005-01-01

The purpose of this paper is to study the demand for energy in two-digit manufacturing sectors of Greece and to evaluate the impact of a carbon tax on energy-related CO 2 emissions. The theoretical model utilized in the analysis is the two-stage translog cost function. The model is estimated using time series data over the period 1982-1998. The results indicate substitutability between electricity and liquid fuels (diesel and mazout), and substitutability between capital, energy and labor. A carbon tax of $50 per tonne of carbon results in a considerable reduction in direct and indirect CO 2 emissions from their 1998 level. This implies that a carbon tax on Greek manufacturing is an environmentally effective policy for mitigating global warming, although a costly one

Avoidance of singularity and global non-conservation of energy in general relativity

International Nuclear Information System (INIS)

Verma, M.M.

2009-06-01

We show that the singularity in the General Theory of Relativity (GTR) is the expression of a non-Machian feature. It can be avoided with a scale-invariant dynamical theory, a property lacking in GTR. It is further argued that the global non-conservation of energy in GTR also results from the lack of scale-invariance, and the field formulation presented by several authors can only partly resolve the problem. Assuming the global energy conservation, we propose a negative energy density component with a positive equation of state that can drive the late-time acceleration in the universe, while the positive component confines to smaller scales.

Dispersion relation and Landau damping of waves in high-energy density plasmas

International Nuclear Information System (INIS)

Zhu Jun; Ji Peiyong

2012-01-01

We present a theoretical investigation on the propagation of electromagnetic waves and electron plasma waves in high energy density plasmas using the covariant Wigner function approach. Based on the covariant Wigner function and Dirac equation, a relativistic quantum kinetic model is established to describe the physical processes in high-energy density plasmas. With the zero-temperature Fermi–Dirac distribution, the dispersion relation and Landau damping of waves containing the relativistic quantum corrected terms are derived. The relativistic quantum corrections to the dispersion relation and Landau damping are analyzed by comparing our results with those obtained in classical and non-relativistic quantum plasmas. We provide a detailed discussion on the Landau damping obtained in classical plasmas, non-relativistic Fermi plasmas and relativistic Fermi plasmas. The contributions of the Bohm potential, the Fermi statistics pressure and relativistic effects to the dispersion relation and Landau damping of waves are quantitatively calculated with real plasma parameters.

Energy and Water Use Related to the Cultivation of Energy Crops: a Case Study in the Tuscany Region

Directory of Open Access Journals (Sweden)

Anna Dalla Marta

2011-06-01

Full Text Available The contribution of agrobiomasses, as a source of energy, to the reduction of greenhouse gas emissions was confirmed by several studies. Biomass from agriculture represents one of the larger and more diverse sources to exploit and in particular ethanol and diesel have the potential to be a sustainable replacement for fossil fuels, mainly for transport purposes. However, the cultivation of energy crops dedicated to the production of biofuels presents some potential problems, e.g., competitiveness with food crops, water needs, use of fertilizers, etc., and the economic, energy, and environmental convenience of such activity depends on accurate evaluations about the global efficiency of the production system. In this study, the processes related to the cultivation of energy crops were analyzed from an energy and water cost perspective. The crops studied, maize (Zea mais and sunflower (Helianthus annuus, were identified for their different water requirements and cultivation management, which in turns induces different energy costs. A 50-year climatic series of meteorological data from 19 weather stations scattered in the Tuscany region was used to feed the crop model CropSyst for the simulation of crop production, water requirement, and cultivation techniques. Obtained results were analyzed to define the real costs of energy crop cultivation, depending on energy and water balances. In the energy crop cultivation, the only positive energy balance was obtained with the more efficient system of irrigation whereas all the other cases provided negative balances. Concerning water, the results demonstrated that more than 1.000 liters of water are required for producing 1 liter of bioethanol. As a consequence, the cultivation of energy crops in the reserved areas of the region will almost double the actual water requirement of the agricultural sector in Tuscany.

Ab initio calculation of reaction energies. III. Basis set dependence of relative energies on the FH2 and H2CO potential energy surfaces

The relative energies of the stationary points on the FH 2 and H 2 CO nuclear potential energy surfaces relevant to the hydrogen atom abstraction, H 2 elimination and 1,2-hydrogen shift reactions have been examined using fourth-order Moller--Plesset perturbation theory and a variety of basis sets. The theoretical absolute zero activation energy for the F+H 2 →FH+H reaction is in better agreement with experiment than previous theoretical studies, and part of the disagreement between earlier theoretical calculations and experiment is found to result from the use of assumed rather than calculated zero-point vibrational energies. The fourth-order reaction energy for the elimination of hydrogen from formaldehyde is within 2 kcal mol -1 of the experimental value using the largest basis set considered. The qualitative features of the H 2 CO surface are unchanged by expansion of the basis set beyond the polarized triple-zeta level, but diffuse functions and several sets of polarization functions are found to be necessary for quantitative accuracy in predicted reaction and activation energies. Basis sets and levels of perturbation theory which represent good compromises between computational efficiency and accuracy are recommended

Driving forces behind the stagnancy of China's energy-related CO2 emissions from 1996 to 1999: the relative importance of structural change, intensity change and scale change

It is noteworthy that income elasticity of energy consumption in China shifted from positive to negative after 1996, accompanied by an unprecedented decline in energy-related CO 2 emissions. This paper therefore investigate the evolution of energy-related CO 2 emissions in China from 1985 to 1999 and the underlying driving forces, using the newly proposed three-level 'perfect decomposition' method and provincially aggregated data. The province-based estimates and analyses reveal a 'sudden stagnancy' of energy consumption, supply and energy-related CO 2 emissions in China from 1996 to 1999. The speed of a decrease in energy intensity and a slowdown in the growth of average labor productivity of industrial enterprises may have been the dominant contributors to this 'stagnancy'. The findings of this paper point to the highest rate of deterioration of state-owned enterprises in early 1996, the industrial restructuring caused by changes in ownership, the shutdown of small-scale power plants, and the introduction of policies to improve energy efficiency as probable factors. Taking into account the characteristics of those key driving forces, we characterize China's decline of energy-related CO 2 emissions as a short-term fluctuation and incline to the likelihood that China will resume an increasing trend from a lower starting point in the near future.

This debate is based on a study recently published by Ifri's Energy Program (Les relations franco-allemandes dans le secteur de l'energie, by Jan Horst Keppler, Sophie Meritet and Kristina Notz). Franco-German energy relations are often dominated by debates on nuclear power and, for many observers, the two countries seem far apart on this question. Indeed, very different political decisions have been made by either country on the issue. Surprisingly, opinion polls have shown that public opinion on nuclear energy is quite similar in both countries. Furthermore, the cooperation between Areva and Siemens in the nuclear field is one of the best examples of Franco-German industrial cooperation. In more general terms, France and Germany have a quite different energy mix and hence both countries have divergent positions concerning some aspects of European energy policy. Positions on nuclear energy phasing-out, electricity networks, energy security and gas supply, fuel substitution, climate change and the development of renewable energy sources, etc. are discussed

Energy as a Bond. Relations with Russia in the Context of Europe and The Netherlands

Handke, S.; De Jong, J.J.

2007-01-01

European countries have been importing large amounts of oil and gas from the Soviet Union and Russia for more than two decades. European energy companies could always rely on their Russian business partners. Despite political and economic upheaval, Russian energy companies fulfilled the contracts with their European partners and shipped the agreed oil and gas supplies to Western Europe, without any delay or extra demands. Today, however, the Russian 'energy weapon' frequently hits the headlines in Western media. Russia's current leadership has been redefining the country's political-economic system and helped the Russian state regain control of the country's resources. These policies are aimed at developing strong positions for the Russian energy industry in global energy markets. Yet, it would be too easy to generalise and suggest that Russia uses energy supplies as a tool in international relations. Russia's current approach is conducted within the country's market economy. The Russian energy industry must be strengthened and consolidated as major investments will have to be made in the energy sectors. These investments are needed to modernise outdated equipment and infrastructure and to keep up with growing domestic demand. Moreover, due to declining production at older fields, Russian energy companies will have to make major efforts to explore and develop new oil and gas fields. The timely beginning of these projects and the use of modern technology will be crucial for securing energy flows to all customers. For decades, Europe has been the most important destination for Russian energy exports. Energy is also the key to the EU's future relations with Russia. The EU imports up to 30% of its oil and gas consumption from Russia. Due to decreasing domestic reserves, the EU will have to import an even larger share of its consumption from Russia. Existing transport infrastructures and the complementary economies make Russia a natural partner for providing energy

Inter-industry relations tables and energy statistics are combined for Asian countries for the preparation of energy analysis oriented inter-industry relations tables, which are used to metrically analyze Aisan nations' industrial structures and energy consumption structures for the ultimate purpose of grasping the magnitude of each industry's demand for energy. The tables prepared this year cover Korea, Indonesia, Thailand, and the Philippines. In Korea, the self-sufficiency rate of mineral fuels is low at 23.1%, which is due to its import of crude oil from abroad. It consumes 177.92-million tons (in terms of oil) of energy for its economic activities, with energy saving measures expected to work effectively here. Indonesia's mineral fuel self-sufficiency rate is high at 84.3% because it is an oil producing country. The energy it consumes for its economic activities is 179.37-million tons (in terms of oil), and energy saving measures will work effectively here. Thailand is a crude oil importing country. Its mineral fuel self-sufficiency rate is 33.4% and the energy its economic activities consume is 53.08-million tons (in terms of oil), and energy saving measures will work effectively in this country. The Philippines is a crude oil importing country and its mineral fuel self-sufficiency rate is as low as 4.8%. It consumes 22.71-million tons of energy (in terms of oil) for its economic activities, and energy-saving measures are expected to take effect here. (NEDO)

Highlights: • The research focuses on agricultural sectors of the eighteen European countries. • The main drivers of energy-related CO_2 emission are quantified by means of IDA. • The slack-based DEA model is applied to gauge the environmental efficiency. • Shadow prices of carbon emission are analysed. • Energy efficiency remains the primary means for increasing environmental efficiency. - Abstract: Climate change mitigation is a key issue in formulating global environmental policies. Energy production and consumption are the main sources of greenhouse gas (GHG) emissions in Europe. Energy consumption and energy-related GHG emissions from agriculture are an important concern for policymakers, as the agricultural activities should meet food security goals along with proper economic, environmental, and social impacts. Carbon dioxide (CO_2) emission is the most significant among energy-related GHG emissions. This paper analyses the main drivers behind energy-related CO_2 emission across agricultural sectors of European countries. The analysis is based on aggregate data from the World Input-Output Database. The research explores two main directions. Firstly, Index Decomposition Analysis (IDA), facilitated by the Shapley index, is used to identify the main drivers of CO_2 emission. Secondly, the Slack-based Model (SBM) is applied to gauge the environmental efficiency of European agricultural sectors. By applying frontier techniques, we also derive the measures of environmental efficiency and shadow prices, thereby contributing to a discussion on CO_2 emission mitigation in agriculture. Therefore, the paper devises an integrated approach towards analysis of CO_2 emission based upon advanced decomposition and efficiency analysis models. The research covers eighteen European countries and the applied methodology decomposes contributions to CO_2 emission across of regions and factors. Results of IDA suggest that decreasing energy intensity is the main factor

Energy Services in Sweden - Customer Relations towards Increased Sustainability

Energy Technology Data Exchange (ETDEWEB)

Sernhed, Kerstin

2008-06-15

Energy use and supply are evident issues to consider for a sustainable development, where the economic, social and environmental aspects are all important. In large grid-bound systems, the supply of energy is usually a rather invisible activity and the contacts between household customers and utilities are sometimes only represented through the energy bill. In this thesis, three particular fields are emphasized where these interactions comes into focus: Electricity peak load problems and load management in households; Energy monitoring and feedback, and; The selling of district heating to households in detached house areas. Improved customer relations in these areas can both increase the energy utilities abilities to compete on the markets and to contribute to an increased sustainable development within the energy sector. The traditional ways to handle peak load problems in the Swedish electricity system have been to build new power plants and to reinforce the electricity grid. However, there are many reasons why solutions should be sought for on the demand-side. This thesis discusses the issues of load management through technical load control of households' electric heating systems and electric water heaters, and through indirect load management with different pricing of electricity.The new Swedish law about monthly accurate billing of electricity for household customers has influenced the electricity network owners to install new automatic meter reading (AMR) systems. Hourly metering can give raise to a new set of data about household electricity use, that can be utilised to provide detailed characteristics of load demand and consumption patterns and serve as a basis for customer segmentation. This information can be useful when developing new energy services, new pricing of electricity, new load management strategies and demand response programs. In this thesis, customer preferences towards feedback on electricity use and different types of billing are

Upper bounds on the relative energy difference of pure and mixed Gaussian states with a fixed fidelity

International Nuclear Information System (INIS)

Dodonov, V V

2012-01-01

Exact and approximate formulas for the upper bound of the relative energy difference of two Gaussian states with a fixed fidelity between them are derived. The reciprocal formulas for the upper bound of the fidelity for the fixed value of the relative energy difference are also obtained. The bounds appear higher for pure states than for mixed ones, and their maximal values correspond to squeezed vacuum states. In particular, to guarantee the relative energy difference less than 10%, for quite arbitrary Gaussian states, the fidelity between them must exceed the level 0.998866. (fast track communication)

Harrington, D M; Martin, C K; Ravussin, E; Katzmarzyk, P T

The aim was to investigate relationships between activity related energy expenditure (AREE), appetite ratings and energy intake (EI) in a sample of 40 male (26.4years; BMI 23.5kg/m(2)) and 42 female (26.9years; BMI 22.4kg/m(2)) participants. AREE was expressed as the residual value of the regression between total daily EE (by doubly labeled water) and resting EE (by indirect calorimetry). EI was measured using an ad libitum buffet meal and visual analogue scales measured subjective appetite ratings before and after the meal. AREE was divided into low, middle and high sex-specific tertiles. General linear models were used to investigate differences in appetite ratings and EI across AREE tertiles. Before the meal, males in the high AREE tertile had significantly lower desire to eat and lower prospective food consumption and higher feelings of fullness compared to those in the low tertile. Males in the middle tertile had significantly higher satiety quotients after the meal and lower EI compared to the other tertiles. No significant differences across tertiles were found in females. Sex differences in relationships between AREE, appetite ratings and EI may lead to differing patterns of EI and subsequent weight maintenance. Copyright © 2013 Elsevier Ltd. All rights reserved.

This report outlines the technical barriers, gaps, and opportunities that arise in executing home energy upgrade market delivery approaches, as identified through research conducted by the U.S. Department of Energy's Building America program. The objective of this report is to outline the technical1 barriers, gaps, and opportunities that arise in executing home energy upgrade market delivery approaches, as identified through research conducted by the U.S. Department of Energy's (DOE) Building America program. This information will be used to provide guidance for new research necessary to enable the success of the approaches. Investigation for this report was conducted via publications related to home energy upgrade market delivery approaches, and a series of interviews with subject matter experts (contractors, consultants, program managers, manufacturers, trade organization representatives, and real estate agents). These experts specified technical barriers and gaps, and offered suggestions for how the technical community might address them. The potential benefits of home energy upgrades are many and varied: reduced energy use and costs; improved comfort, durability, and safety; increased property value; and job creation. Nevertheless, home energy upgrades do not comprise a large part of the overall home improvement market. Residential energy efficiency is the most complex climate intervention option to deliver because the market failures are many and transaction costs are high (Climate Change Capital 2009). The key reasons that energy efficiency investment is not being delivered are: (1) The opportunity is highly fragmented; and (2) The energy efficiency assets are nonstatus, low-visibility investments that are not properly valued. There are significant barriers to mobilizing the investment in home energy upgrades, including the 'hassle factor' (the time and effort required to identify and secure improvement works), access to financing, and the

Nowadays, most people spend more than 90% of their time indoors, therefore the quality of the indoor environment has a significant impact on human health. However, improving indoor environment quality (IEQ) requires a higher energy consumption through increasing lighting, heating and cooling. The aim of this study is to determine an appropriate level of IEQ with the least energy consumption possible. The relation between energy consumption and IEQ in 2 offices in Iran has been studied through the use of questionnaires and simulations. It was found that IEQ has a great impact on workers' productivity and that diminishing the energy consumption does not necessarily translate into economic benefits. In addition it was found that lighting and heating are the main sources of energy consumption and that noise and light are what most influence worker productivity. This study highlighted the relation between energy consumption and IEQ and pointed out the most important factors.

INTERPRETING ERUPTIVE BEHAVIOR IN NOAA AR 11158 VIA THE REGION'S MAGNETIC ENERGY AND RELATIVE-HELICITY BUDGETS

Tziotziou, Kostas; Georgoulis, Manolis K.; Liu Yang

2013-01-01

In previous works, we introduced a nonlinear force-free method that self-consistently calculates the instantaneous budgets of free magnetic energy and relative magnetic helicity in solar active regions (ARs). Calculation is expedient and practical, using only a single vector magnetogram per computation. We apply this method to a time series of 600 high-cadence vector magnetograms of the eruptive NOAA AR 11158 acquired by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory over a five-day observing interval. Besides testing our method extensively, we use it to interpret the dynamical evolution in the AR, including eruptions. We find that the AR builds large budgets of both free magnetic energy and relative magnetic helicity, sufficient to power many more eruptions than the ones it gave within the interval of interest. For each of these major eruptions, we find eruption-related decreases and subsequent free-energy and helicity budgets that are consistent with the observed eruption (flare and coronal mass ejection (CME)) sizes. In addition, we find that (1) evolution in the AR is consistent with the recently proposed (free) energy-(relative) helicity diagram of solar ARs, (2) eruption-related decreases occur before the flare and the projected CME-launch times, suggesting that CME progenitors precede flares, and (3) self terms of free energy and relative helicity most likely originate from respective mutual terms, following a progressive mutual-to-self conversion pattern that most likely stems from magnetic reconnection. This results in the non-ideal formation of increasingly helical pre-eruption structures and instigates further research on the triggering of solar eruptions with magnetic helicity firmly placed in the eruption cadre

Essays on the Determinants of Energy Related CO2 Emissions =

emissions intensity is negative. The percentage of fossil fuels used reacts positively to the economic structure and to carbon intensity, i. e., the more the economic importance of the sector, the more it uses fossil fuels, and when it raises its carbon intensity, in the future the use of fossil fuel may rise. On the other hand, positive shocks on energy intensity tend to reduce the percentage of fossil fuels used. In fourth essay, we conducted an analysis to identify the effects that contribute to the intensity of GHG emissions (EI) in agriculture as well as their development. With that aim, we used the 'complete decomposition' technique in the 1995-2008 periods, for a set of European countries. It is shown that the use of Nitrogen per cultivated area is an important factor of emissions and in those countries where labour productivity increases (the inverse of average labour productivity in agriculture decreases), emissions intensity tends to decrease. These results imply that the way to reduce emissions in agriculture would be to provide better training of agricultural workers to increase their productivity, which would lead to a less need for energy and use of Nitrogen. The purpose of the last essay is to examine the long and short-run causality of the share of renewable sources on the environmental relation CO2 per KWh electricity generation- real GDP for 20 European countries over the 2001-2010 periods. It is important to analyze how the percentage of renewable energy used for electricity production affects the relationship between economic growth and emissions from this sector. The study of these relationships is important from the point of view of environmental and energy policy as it gives us information on the costs in terms of economic growth, on the application of restrictive levels of emissions and also on the effects of the policies concerning the use of renewable energy in the electricity sector (see for instance European Commission Directive 2001/77/EC, [4

Triton-3He relative and differential flows as probes of the nuclear symmetry energy at supra-saturation densities

Using a transport model coupled with a phase-space coalescence afterburner, we study the triton- 3 He (t- 3 He) ratio with both relative and differential transverse flows in semicentral 132 Sn+ 124 Sn reactions at a beam energy of 400 MeV/nucleon. The neutron-proton ratios with relative and differential flows are also discussed as a reference. We find that similar to the neutron-proton pairs, the t- 3 He pairs also carry interesting information regarding the density dependence of the nuclear symmetry energy. Moreover, the nuclear symmetry energy affects more strongly the t- 3 He relative and differential flows than the π - /π + ratio in the same reaction. The t- 3 He relative flow can be used as a particularly powerful probe of the high-density behavior of the nuclear symmetry energy.

Activity-related energy expenditure during lower limb cast immobilization in children.

Maggio, Albane B; Martin, Xavier E; Ceroni, Dimitri

2017-05-01

Physical inactivity, which may result from immobilization, is recognized as a risk factor for the development of obesity. We aimed to quantify the decrease in activity-related energy expenditure (AEE) because of lower limb cast immobilization. We carried out a longitudinal matched case-control study: 34 adolescents with a first episode of lower limb fracture and 34 healthy cases. Physical activity was assessed during cast immobilization by an accelerometer from which we calculated the decrease in AEE. AEE in adolescents with lower limb fractures was estimated to be 16.0% lower than healthy controls. When converted into kcal per mean participants' weight, the difference in AEE amounted to 125 kcal/day, which corresponds to 5.2 h of slow walking. A significant reduction of AEE in adolescents with lower limb fractures may lead to a significantly positive energy balance as there is usually no compensatory reduction of energy intake. An increase of walking seems unrealistic in this situation and patients should be advised at the emergency unit to reduce their energy intake during the immobilization period. Level III, prospective case-control study.

In this paper, theoretical model for calculating halo current has been developed. This work attained novelty as no theoretical calculations for halo current has been reported so far. This is the first time to use theoretical approach. The research started by calculating points for plasma energy in terms of poloidal and toroidal magnetic field orientations. While calculating these points, it was extended to calculate halo current and to developed theoretical model. Two cases were considered for analyzing the plasma energy when flows down/upward to the diverter. Poloidal as well as toroidal movement of plasma energy was investigated and mathematical formulations were designed as well. Two conducting points with respect to (R, Z) were calculated for halo current calculations and derivations. However, at first, halo current was established on the outer plate in clockwise direction. The maximum generation of halo current was estimated to be about 0.4 times of the plasma current. A Matlab program has been developed to calculate halo current and plasma energy calculation points. The main objective of the research was to establish theoretical relation with experimental results so as to precautionary evaluate the plasma behavior in any Tokamak.

Within the European research project Health Optimisation Protocol for Energy-efficient Building (HOPE), 96 apartment buildings and 64 office buildings (of which approximately 75% have been designed to be energy-efficient) were investigated. The building characteristics were assessed according to a checklist during a walk-through survey. Occupant questionnaires were used to determine satisfaction about comfort (thermal visual, acoustical and indoor air quality (IAQ)) and their health (Sick Building Syndrome and allergies). Building-averaged collected data are compared, looking for correlations between building characteristics on one hand, and perceived comfort and health on the other hand. Strong correlations are found between perceived IAQ, thermal, acoustic and lighting comfort, confirming results from other studies. Significant correlations between the perceived comfort and building related symptoms were also found, comfortable and healthier buildings being well distinct from uncomfortable ones. Differences of perceived comfort or health between low- and high-energy buildings show that it is possible to design buildings that are healthy, comfortable and energy efficient. (author)

Federally Funded Programs Related to Building Energy Use: Overlaps, Challenges, and Opportunities for Collaboration

As energy efficiency in buildings continues to move from discreet technology development to an integrated systems approach, the need to understand and integrate complementary goals and targets becomes more pronounced. Whether within Department of Energy’s (DOE) Building Technologies Program (BTP), across the Office of Energy Efficiency and Renewable Energy (EERE), or throughout DOE and the Federal government, mutual gains and collaboration synergies exist that are not easily achieved because of organizational and time constraints. There also cases where federal agencies may be addressing similar issues, but with different (and sometimes conflicting) outcomes in mind. This report conducts a comprehensive inventory across all EERE and other relevant Federal agencies of potential activities with synergistic benefits. A taxonomy of activities with potential interdependencies is presented. The report identifies a number of federal program objectives, products, and plans related to building energy efficiency and characterizes the current structure and interactions related to these plans and programs. Areas where overlap occurs are identified as are the challenges of addressing issues related to overlapping goals and programs. Based on the input gathered from various sources, including 20 separate interviews with federal agency staff and contractor staff supporting buildings programs, this study identifies a number of synergistic opportunities and makes recommends a number of areas where further collaboration could be beneficial.

Nearly Zero Energy Standard for Non-Residential Buildings with high Energy Demands—An Empirical Case Study Using the State-Related Properties of BAVARIA

Directory of Open Access Journals (Sweden)

Michael Keltsch

2017-03-01

Full Text Available The Energy Performance of Buildings Directive (EPBD 2010 calls for the Nearly Zero Energy Building (nZEB Standard for new buildings from 2021 onwards: Buildings using “almost no energy” are powered by renewable sources or by the energy produced by the building itself. For residential buildings, this ambitious new standard has already been reached. But for other building types, this goal is still far away. The potential of these buildings to meet a nZEB Standard was investigated by analyzing ten case studies, representing non-residential buildings with different uses. The analysis shows that the primary characteristics common to critical building types are a dense building context with a very high degree of technical installation (such as hospital, research, and laboratory buildings. The large primary energy demand of these types of buildings cannot be compensated by building- and property-related energy generation, including off-site renewables. If the future nZEB Standard were to be defined with lower requirements because of this, the state-related properties of Bavaria suggest that the real potential energy savings available in at least 85% of all new buildings would be insufficiently exploited. Therefore, it would be more useful to individualize the legal energy verification process for new buildings, to distinguish critical building types such as laboratories and hospitals from the other building types.

Accurate in silico prediction of protein-ligand binding affinities has been a primary objective of structure-based drug design for decades due to the putative value it would bring to the drug discovery process. However, computational methods have historically failed to deliver value in real-world drug discovery applications due to a variety of scientific, technical, and practical challenges. Recently, a family of approaches commonly referred to as relative binding free energy (RBFE) calculations, which rely on physics-based molecular simulations and statistical mechanics, have shown promise in reliably generating accurate predictions in the context of drug discovery projects. This advance arises from accumulating developments in the underlying scientific methods (decades of research on force fields and sampling algorithms) coupled with vast increases in computational resources (graphics processing units and cloud infrastructures). Mounting evidence from retrospective validation studies, blind challenge predictions, and prospective applications suggests that RBFE simulations can now predict the affinity differences for congeneric ligands with sufficient accuracy and throughput to deliver considerable value in hit-to-lead and lead optimization efforts. Here, we present an overview of current RBFE implementations, highlighting recent advances and remaining challenges, along with examples that emphasize practical considerations for obtaining reliable RBFE results. We focus specifically on relative binding free energies because the calculations are less computationally intensive than absolute binding free energy (ABFE) calculations and map directly onto the hit-to-lead and lead optimization processes, where the prediction of relative binding energies between a reference molecule and new ideas (virtual molecules) can be used to prioritize molecules for synthesis. We describe the critical aspects of running RBFE calculations, from both theoretical and applied perspectives

Sharma, S.K.; Williamson, D.; Treichel, L.C.; James, L.M.

1996-01-01

The US Department of Energy (DOE) Office of Environmental Restoration (EM-40) has developed the Relative Ranking Evaluation Framework (RREF) to help categorize release sites, facilities and buildings requiring restoration or decommissioning. Based on this framework, a computer tool, the Relative Rank Evaluation Program (RREP) has been developed to evaluate release sites, facilities and buildings, and to manage information pertaining to relative ranking evaluations. The relative ranking information is being used by both Headquarters and field project managers, and other environmental personnel responsible for planning, executing and evaluation environmental restoration activities at DOE installations. External stakeholders, such as representatives of federal and state regulatory agencies, local governments and communities in the vicinity of current and formerly used DOE installations may use this data to review proposed and planned activities

The project to design and develop an energy-related program for public housing residents: Final report

Energy Technology Data Exchange (ETDEWEB)

1986-12-01

This demonstration project studied how to minimize the costs associated with public housing tenants in standard public housing as well as under homeownership transfers. A related problem was how to graduate the tenants to another level of responsibility and self-sufficiency through resident business developments and training in energy-related fields. The goal that emanated was the design and development of an energy-related demonstration program that educates public housing residents, facilities indigenous business development where appropriate, and trains residents to provide needed services.

Insight is given into of the developments in the sector energy distribution companies and the consequences for the demand for energy services. Next, an overview is given of which energy services should be developed to meet the changed needs of the market. Three scenarios have been set up and are discussed in this brochure: (1) a Steady State scenario (unchanged policy of energy distribution companies); (2) Alliance scenario (strategic cooperation between energy distribution companies and retailers and installation businesses); and (3) Autonomous Development scenario (energy distribution companies develop and offer new services)

Kerr-Taub-NUT General Frame, Energy, and Momentum in Teleparallel Equivalent of General Relativity

Directory of Open Access Journals (Sweden)

Gamal G. L. Nashed

2012-01-01

Full Text Available A new exact solution describing a general stationary and axisymmetric object of the gravitational field in the framework of teleparallel equivalent of general relativity (TEGR is derived. The solution is characterized by three parameters “the gravitational mass M, the rotation a, and the NUT L.” The vierbein field is axially symmetric, and the associated metric gives the Kerr-Taub-NUT spacetime. Calculation of the total energy using two different methods, the gravitational energy momentum and the Riemannian connection 1-form Γα̃β, is carried out. It is shown that the two methods give the same results of energy and momentum. The value of energy is shown to depend on the mass M and the NUT parameter L. If L is vanishing, then the total energy reduced to the energy of Kerr black hole.

2014-01-01

Achievement of carbon emission reduction targets proposed by national governments relies on provincial/state allocations. In this study, a hybrid method for provincial energy-related carbon emissions allocation in China was developed to provide a good balance between production- and consumption-based approaches. In this method, provincial energy-related carbon emissions are decomposed into direct emissions of local activities other than thermal power generation and indirect emissions as a result of electricity consumption. Based on the carbon reduction efficiency principle, the responsibility for embodied emissions of provincial product transactions is assigned entirely to the production area. The responsibility for carbon generation during the production of thermal power is borne by the electricity consumption area, which ensures that different regions with resource endowments have rational development space. Empirical studies were conducted to examine the hybrid method and three indices, per capita GDP, resource endowment index and the proportion of energy-intensive industries, were screened to preliminarily interpret the differences among China's regional carbon emissions. Uncertainty analysis and a discussion of this method are also provided herein.

Consumer lifestyle approach to US energy use and the related CO2 emissions

Bin Shui; Dowlatabadi, Hadi

2005-01-01

Historically, a sectoral approach (based on the industrial, transportation, commercial, and residential sectors) has shaped the way we frame and analyze issues of energy conservation and CO 2 mitigation. This sectoral categorization, however, is limited in its capacity to reveal the total impacts of consumer activities on energy use and its related environmental impacts. In this paper, we propose an alternative paradigm, called the Consumer Lifestyle Approach (CLA), to explore the relationship between consumer activities and environmental impacts in the US. Estimates based on our methodology reveal that more than 80% of the energy used and the CO 2 emitted in the US are a consequence of consumer demands and the economic activities to support these demands. Direct influences due to consumer activities (home energy use and personal travel) are 4% of the US GDP, but account for 28% and 41% of US energy use and CO 2 emissions, respectively. Indirect influences (such as housing operations, transportation operations, food, and apparel) involve more than twice the direct energy use and CO 2 emissions. Characterization of both direct and indirect energy use and emissions is critical to the design of more effective energy and CO 2 emission policies. It may also help erode the false dichotomy of 'them versus us' (industrial polluters versus consumers) references to the locus of responsibility for control of energy use and CO 2 emissions

Securing Gender Equality through a Nexus of Energy Policy Performance and Relative Political Performance

Science.gov (United States)

Perkins-Ozuagiemhe, Andrea Christen

This dissertation presents what is believed to be the first empirical study that measures the effect of increasing access to modern household energy sources upon advancing gender equality within developing countries. As a powerful and fundamental public infrastructural socio-economic building block, improved access to modern energy in developing countries delivers the necessary economic ingredient of time as a major component of household production and consumption and captures the interdependence between market and household economies. Thus, because it has been empirically proven that men and women differ in their utilization of household energy with women spending more time engaged in non-market household labor than men, improving access to modern household energy in developing countries, especially in rural areas, theoretically would disproportionately affect women's lives. Essentially, the element of "time" not only extends the day for women to use towards more economically and educationally productive activities, but also lessens the burden of domestic chores from women with technological advancements in more time-efficient household appliances and cleaner modern energy sources. This dissertation introduces gender differentiation in a model in the form of a gender relative status composite measure comparing socio-economic achievements in secondary education, life expectancy, and labor force participation rates by varying degree of demographic transition, thereby, measuring the effect of improved access to modern household energy upon overall gender equality. Fixed effects panel regressions employing a Driscoll-Kraay non-parametric covariance matrix, and estimated and interpreted adjusted predictions and marginal effects of the two-way interaction between a country's available access to residential electric power (kWh per capita) and the level of relative political performance against predicted values of gender relative status are employed. The models confirm

Improving literacy around energy-related issues: The need for a better understanding of the concepts behind energy intake and expenditure among adolescents and their parents

Despite the need for effective obesity prevention strategies, little research is currently available to assess adolescents’ knowledge around basic concepts of energy intake, expenditure and balance. Using data from 349 adolescent-caregiver pairs (recruited from Minneapolis/St. Paul metro region, MN, 2006-2007), cross-sectional linear regression was used to assess adolescent and parental knowledge related to energy intake and expenditure as a predictor of adolescent weight-related behaviors an...

An Analysis of the Bilateral Relations Between Qatar and Japan: Case Studies on Energy, Culture and Diplomacy

Science.gov (United States)

Al Subaey, Maha Khalid

Energy is considered as an important pillar in the establishment of international relations where it plays a heavy role in shaping the relations. In the light of this, an analysis of the Qatar-Japan relations will be studied through the case study of energy security along with the culture and diplomacy spectrum. The research aims to assess the bilateral relationship in terms of the projects and the Liquefied Natural Gas (LNG) trade and the further development in the energy sector. This will take into consideration the growing interdependence in the projects in different sectors: infrastructure, trade and cultural projects. Also, the direct involvement of the Qatari and Japanese societies in the relationship. The LNG trade along with view on the joint ventures and other types of contracts would be adopted to elaborate over the energy cooperation. The energy plays a significant role in the relationship and classifying it as an economically driven. Further more, the bilateral relationship is classified as complex interdependence approach' that was supported by the theory of soft power.

Morality and nuclear energy: perceptions of risks and benefits, personal norms, and willingness to take action related to nuclear energy.

Science.gov (United States)

De Groot, Judith I M; Steg, Linda

2010-09-01

We examined factors underlying people's willingness to take action in favor of or against nuclear energy from a moral perspective. We conducted a questionnaire study among a sample of the Dutch population (N = 123). As expected, perceptions of risks and benefits were related to personal norms (PN), that is, feelings of moral obligation toward taking action in favor of or against nuclear energy. In turn, PN predicted willingness to take action. Furthermore, PN mediated the relationships between perceptions of risk and benefits and willingness to take action. In line with our hypothesis, beliefs about the risks and benefits of nuclear energy were less powerful in explaining PN for supporters compared to PN of opponents. Also, beliefs on risks and benefits and PN explained significantly more variance in willingness to take action of opponents than of supporters. Our results suggest that a moral framework is useful to explain willingness to take action in favor of and against nuclear energy, and that people are more likely to protest in favor of or against nuclear energy when PN are strong. © 2010 Society for Risk Analysis.

A model of milk production in lactating dairy cows in relation to energy and nitrogen dynamics.

Johnson, I R; France, J; Cullen, B R

2016-02-01

A generic daily time-step model of a dairy cow, designed to be included in whole-system pasture simulation models, is described that includes growth, milk production, and lactation in relation to energy and nitrogen dynamics. It is a development of a previously described animal growth and metabolism model that describes animal body composition in terms of protein, water, and fat, and energy dynamics in relation to growth requirements, resynthesis of degraded protein, and animal activity. This is further developed to include lactation and fetal growth. Intake is calculated in relation to stage of lactation, pasture availability, supplementary feed, and feed quality. Energy costs associated with urine N excretion and methane fermentation are accounted for. Milk production and fetal growth are then calculated in relation to the overall energy and nitrogen dynamics. The general behavior of the model is consistent with expected characteristics. Simulations using the model as part of a whole-system pasture simulation model (DairyMod) are compared with experimental data where good agreement between pasture, concentrate and forage intake, as well as milk production over 3 consecutive lactation cycles, is observed. The model is shown to be well suited for inclusion in large-scale system simulation models. Copyright © 2016 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

Energy-related risk in the U.S.A. in the year 2020

International Nuclear Information System (INIS)

Inhaber, H.; King, S.

1986-01-01

The present risk to health of energy systems has been the subject of much debate in recent years. This paper extrapolates some present results on energy-related risk to the year 2020. It finds that if today's trends continue, the largest sources of risk will be due to the changeover from large to small cars, radon buildup in better-sealed buildings and the entire coal (and synthetic fuel) cycle. Other sources of risk, such as the larger proportion of nuclear and solar energy three or four decades from now, are about an order of magnitude lower than the aforementioned three. Because of the many uncertainties in the calculations, the results should be viewed as primarily qualitative, although derived quantitatively. However, they can be used as a guide by policymakers and research planners to produce the greatest risk reduction per unit effort. (author)

Mitigating climate change: Decomposing the relative roles of energy conservation, technological change, and structural shift

International Nuclear Information System (INIS)

Mishra, Gouri Shankar; Zakerinia, Saleh; Yeh, Sonia; Teter, Jacob; Morrison, Geoff

2014-01-01

We decompose the contribution of five drivers of energy use and CO 2 emissions reductions in achieving climate change goals over 2005–2100 for various climate policy scenarios. This study contributes to the decomposition literature in three ways. First, it disaggregates drivers of energy demand into technological progress and demand for energy services, represented in terms of useful energy, allowing us to estimate their contributions independently — an improvement over other economy-wide decomposition studies. Secondly, this approach reduces the ambiguity present in many previous measures of structural change. We delineate structural shifts into two separate measures: changes in fuel mix within a given resource or service pathway; and changes in mix among distinct energy resources or end-use services. Finally, this study applies decomposition methods to energy and emission trajectories from two mutually informing perspectives: (i) primary energy resources — crude oil, natural gas, coal, nuclear, and renewables; and (ii) end-uses of energy services — residential and commercial buildings, industry, and transportation. Our results show that technological improvements and energy conservation are important in meeting climate goals in the first half of the coming century; and that nuclear and renewable energy and CCS technology are crucial in meeting more stringent goals in the second half of the century. We examine the relative roles of the drivers in reducing CO 2 emissions separately for developed and developing regions. Although the majority of energy and emission growth – and by extension the greatest opportunities for mitigation – will occur in developing countries, the decomposition shows that the relative roles of the five drivers are broadly consistent between these two regions. - Highlights: • We decompose the contribution of five drivers of energy use and CO2 emissions reductions in achieving climate change goals • We analyze differences

Public participation in energy related decision making: Six case studies. Final report

Clemente, F.; Cole, J.; Kloman, E.; McCabe, J.; Sawicki, P.

1977-12-01

Each of the six case studies documents public participation in Federal and/or state governmental decisions related to energy facility siting. Four of the cases involved decisions on specific facilities at specific sites, namely: (1) various state and federal licensing procedures for the Seabrook, New Hampshire nuclear facility; (2) the Maine Environmental Improvement Commission's denial of a permit for an oil refinery on Sears Island in Penobscot Bay; (3) the Atomic Energy Commission's amendment to the license for the Big Rock Point, Michigan, nuclear reactor to allow an increased level of plutonium-enriched fuel use; (4) the AEC's review, arising from disclosure of a geological fault, of the North Anna River, Virginia, nuclear facility. A fifth case documents a series of public meetings conducted in Pennsylvania by the Governor's Energy Council to consider the energy park concept. The sixth study was a narrative history and analysis of RM-50-1, a rulemaking proceeding conducted by the AEC in 1972 and 73 on emergency core cooling system operating standards.

THE INFLUENCE OF ENERGY RESOURCES IN DEVELOPING “PRAGMATIC” RELATIONS BETWEEN AZERBAIJAN AND THE WEST

Directory of Open Access Journals (Sweden)

Sabina STRIMBOVSCHI

2016-10-01

Full Text Available The aim of the paper is to research the way energy resources shaped Azerbaijan’s foreign policy and contributed to developing its strategic relations with western actors trying, at the same time, to bring arguments whether or not the democratic deficit in Azerbaijan is related to the”resource nationalism”. The author makes a retrospective analysis of the most important events that have influenced Azerbaijan’s foreign policy since the collapse of USSR. In this regard, it is assessed the impact of the “Contract of the Century” on the evolution of the country, forasmuch the signing of the document is considered the first strategic move made by Azerbaijan since 1991. Because Nagorno-Karabakh is a crucial priority for the country’s territorial integrity, it is examined the manner in which Azerbaijani authorities are trying to make use of the energy resources projects in order to speed up the settlement of the protracted conflict, but without success so far. Last but not least, are analysed the EU-Azerbaijan relations, both on the energy and political level, highlighting on the one hand, the reluctance of Azerbaijan towards the democratic reforms promoted within the Eastern Partnership, but on the other hand, the interest of Baku to negotiate the unwanted agreements with Brussels, counting on its advantage as a supplier of energy resources on the European market. Consequently, some key questions have emerged: Is the EU’s strategic objective to ensure its energy security more important than promoting and encouraging its partners to adopt the fundamental values of the EU? What impact may have the Strategic modernization partnership on the EU-Azerbaijan relations? Is European Union’s credibility in danger, by having so diverse approaches towards the Eastern Partnership countries?

The IOC consensus statement: beyond the Female Athlete Triad--Relative Energy Deficiency in Sport (RED-S).

Protecting the health of the athlete is a goal of the International Olympic Committee (IOC). The IOC convened an expert panel to update the 2005 IOC Consensus Statement on the Female Athlete Triad. This Consensus Statement replaces the previous and provides guidelines to guide risk assessment, treatment and return-to-play decisions. The IOC expert working group introduces a broader, more comprehensive term for the condition previously known as 'Female Athlete Triad'. The term 'Relative Energy Deficiency in Sport' (RED-S), points to the complexity involved and the fact that male athletes are also affected. The syndrome of RED-S refers to impaired physiological function including, but not limited to, metabolic rate, menstrual function, bone health, immunity, protein synthesis, cardiovascular health caused by relative energy deficiency. The cause of this syndrome is energy deficiency relative to the balance between dietary energy intake and energy expenditure required for health and activities of daily living, growth and sporting activities. Psychological consequences can either precede RED-S or be the result of RED-S. The clinical phenomenon is not a 'triad' of the three entities of energy availability, menstrual function and bone health, but rather a syndrome that affects many aspects of physiological function, health and athletic performance. This Consensus Statement also recommends practical clinical models for the management of affected athletes. The 'Sport Risk Assessment and Return to Play Model' categorises the syndrome into three groups and translates these classifications into clinical recommendations.

In order to make the predictions necessary to forecast the ecological consequences of an energy-related technology, there must be an understanding of: the biogeochemical processes involved in the natural system; the manner in which an energy technology affects these processes and how, in turn, this affects the ecosystem as a whole. Direct biological effects such as lethality, behavioral changes, and physiological changes, are being studied under the program previously discussed. The biological availability and impact studies are investigating: the chemical, physical, and biological processes that occur in the natural marine ecosystem; how energy effluents affect these processes; and the factors involved in regulating the bioavailability of effluent material. This past year's effort has centered on defining the quantities and forms of metals and radioisotopes in nuclear power plant effluent streams, the chemical forms present in bioassay systems, the chemical and microbial processes controlling the forms of metals available from the sediments, and the uptake and control of copper in shrimp. In addition, several sites in Sequim Bay have been monitored for potential use in field verification studies

Review of relative biological effectiveness dependence on linear energy transfer for low-LET radiations

International Nuclear Information System (INIS)

Hunter, Nezahat; Muirhead, Colin R

2009-01-01

Information on Japanese A-bomb survivors exposed to gamma radiation has been used to estimate cancer risks for the whole range of photon (x-rays) and electron energies which are commonly encountered by radiation workers in the work place or by patients and workers in diagnostic radiology. However, there is some uncertainty regarding the radiation effectiveness of various low-linear energy transfer (low-LET) radiations (x-rays, gamma radiation and electrons). In this paper we review information on the effectiveness of low-LET radiations on the basis of epidemiological and in vitro radiobiological studies. Data from various experimental studies for chromosome aberrations and cell transformation in human lymphocytes and from epidemiological studies of the Japanese A-bomb survivors, patients medically exposed to radiation for diagnostic and therapeutic procedures, and occupational exposures of nuclear workers are considered. On the basis of in vitro cellular radiobiology, there is considerable evidence that the relative biological effectiveness (RBE) of high-energy low-LET radiation (gamma radiation, electrons) is less than that of low-energy low-LET radiation (x-rays, betas). This is a factor of about 3 to 4 for 29 kVp x-rays (e.g. as in diagnostic radiation exposures of the female breast) and for tritium beta-rays (encountered in parts of the nuclear industry) relative to Co-60 gamma radiation and 2-5 MeV gamma-rays (as received by the Japanese A-bomb survivors). In epidemiological studies, although for thyroid and breast cancer there appears to be a small tendency for the excess relative risks to decrease as the radiation energy increases for low-LET radiations, it is not statistically feasible to draw any conclusion regarding an underlying dependence of cancer risk on LET for the nominally low-LET radiations.

This report provides information on the recent commercial progress of inventions supported by the US Department of Energy`s Energy-Related Inventions Programs (ERIP). It describes the results of the latest in a series of ERIP evaluation projects that have been completed since 1980. It focuses on the economic impacts of the program, notably sales and employment benefits. The period of interest is 1980 through 1990. The evaluation is based on data collected through mail and telephone surveying of 143 participants in the Program. As of October 1989, a total of 486 inventions were recommended to DOE by the National Institute for Standards and Technology, which screens all submitted inventions in terms of technical merit, potential for commercial success, and potential energy impact. By the end of 1990, at least 109 of these inventions had entered the market, generating total cumulative sales of more than $500 million. With $25.7 million in grants awarded from 1975 through 1990, and $63.1 million in program appropriations over the same period, ERIP has generated a 20:1 return in terms of sales values to grants, and an 8:1 return in sales versus program appropriations. It is estimated that 25% of all ERIP inventions had achieved sales by the end of 1990. While it is difficult to make exact comparisons between these percentages and other indicators of the success rates of technological innovations as a whole, the ERIP figures remain impressive. The commercial progress of spin-off technologies is also documented.

The decoupling elasticity decomposition quantitative model of energy-related carbon emission in Guangdong is established based on the extended Kaya identity and Tapio decoupling model for the first time, to explore the decoupling relationship and its internal mechanism between energy-related carbon emission and economic growth in Guangdong. Main results are as follows. (1) Total production energy-related carbon emissions in Guangdong increase from 4128 × 10⁴ tC in 1995 to 14396 × 10⁴ tC in 2011. Decoupling elasticity values of energy-related carbon emission and economic growth increase from 0.53 in 1996 to 0.85 in 2011, and its decoupling state turns from weak decoupling in 1996-2004 to expansive coupling in 2005-2011. (2) Land economic output and energy intensity are the first inhibiting factor and the first promoting factor to energy-related carbon emission decoupling from economic growth, respectively. The development speeds of land urbanization and population urbanization, especially land urbanization, play decisive roles in the change of total decoupling elasticity values. (3) Guangdong can realize decoupling of energy-related carbon emission from economic growth effectively by adjusting the energy mix and industrial structure, coordinating the development speed of land urbanization and population urbanization effectively, and strengthening the construction of carbon sink.

Despite the need for effective obesity prevention strategies, little research has assessed adolescents' knowledge about basic concepts of energy intake, expenditure, and balance. Using data from 349 adolescent-caregiver pairs (recruited from Minneapolis/St Paul, MN metro region, 2006-2007), cross-sectional linear regression was used to assess adolescent and parental knowledge related to energy intake and expenditure as a predictor of adolescent weight-related behaviors and outcomes. Findings indicated that knowledge related to energy intake and expenditure was highly variable, with a substantial proportion of participants (particularly adolescents) lacking knowledge on a range of concepts. Adolescent knowledge was positively associated with moderate physical activity and negatively associated with television viewing (Pfast food intake, weight status, and/or body composition. Although overall parental knowledge was a significant predictor of adolescent knowledge (Phealth promotion strategies are insufficient to initiate long-term healthful behavior change. Educational strategies may be effective when combined with those also targeting familial, social, and environmental influences. The examination of interactive effects between individual-level and environmental influences on health behavior is an important area for future obesity-related research.

A coarse grained description of time evolution: Irreversible state reduction and time-energy relation

International Nuclear Information System (INIS)

Bonifacio, R.; Milan Univ.

1983-05-01

We show that a proper coarse-grained description of time evolution leads to a finite difference equation with step tau for the density operator. This implies state reduction to the diagonal form in the energy representation and a quasi ergodic behaviour of quantum mechanical ensemble averages. An intrinsic time-energy relation tauΔE>=(h/2π)/2 is proposed, and its equivalence to a time quantization is discussed. (author)

that was necessary not only to make fluid injections safe, but an economic asset, DOE organized a series of workshops. The first workshop was held on February 4, 2010, at Stanford University. A second workshop will be held in mid-2010 to address the critical elements of a 'best practices/protocol' that industry could use as a guide to move forward with safe implementation of fluid injections/production for energy-related applications, i.e., a risk mitigation plan, and specific recommendations for industry to follow. The objectives of the first workshop were to identify critical technology and research needs/approaches to advance the understanding of induced seismicity associated with energy related fluid injection/production, such that: (1) The risk associated with induced seismicity can be reduced to a level that is acceptable to the public, policy makers, and regulators; and (2) Seismicity can be utilized/controlled to monitor, manage, and optimize the desired fluid behavior in a cost effective fashion. There were two primary goals during the workshop: (1) Identify the critical roadblocks preventing the necessary understanding of human-induced seismicity. These roadblocks could be technology related (better imaging of faults and fractures, more accurate fluid tracking, improved stress measurements, etc.), research related (fundamental understanding of rock physical properties and geochemical fluid/rock interactions, development of improved constitutive relations, improved understanding of rock failure, improved data processing and modeling, etc.), or a combination of both. (2) After laying out the roadblocks the second goal was to identify technology development and research needs that could be implemented in the near future to address the above objectives.

Highlights: • The He-related clusters exhibit the very high symmetry. • The trapping capability of vacancy to defects becomes weak due to the pre-existed SIA. • The average length of He{sub N}V{sub 1} clusters is longer than one of He{sub N} and He{sub N}V{sub 1}SIA{sub 1} cluster. - Abstract: Using molecular dynamics simulation, we investigated the energy and stability of helium-related cluster in nickel. All the binding energies of the He-related clusters are demonstrated to be positive and increase with the cluster sizes. Due to the pre-existed self-interstitial nickel atom, the trapping capability of vacancy to defects becomes weak. Besides, the minimum energy configurations of He-related clusters exhibit the very high symmetry in the local atomistic environment. And for the He{sub N} and He{sub N}V{sub 1}SIA{sub 1} clusters, the average length of He–He bonds shortens, but it elongates for the He{sub N}V{sub 1} clusters with helium cluster sizes. The helium-to-vacancy ratio plays a decisive role on the binding energies of He{sub N}V{sub M} cluster. These results can provide some excellent clues to insight the initial stage of helium bubbles nucleation and growth in the Ni-based alloys for the Generation-IV Molten Salt Reactor.

Energy situation and energy-related environment issues of Pacific Island countries

Pacific Islands have experienced low economic growth during the 1980s, and face significant energy problems. Petroleum products are imported at very high prices and biofuel use often leads to resource over-exploitation. However, perhaps the most basic energy-environment concern is the potential for sea level rise. Some Pacific Island nations would vanish altogether, while others would lose their most productive areas. (author)

The energy-related inventions program: Continuing benefits to the inventor community

Energy Technology Data Exchange (ETDEWEB)

Braid, R.B. Jr.; Brown, M.A.; Wilson, C.R.; Franchuk, C.A.; Rizy, C.G.

This report provides information on the economic, energy, and environmental impacts of inventions supported by the Energy-Related Inventions Program (ERIP) - a technology commercialization program jointly operated by the U.S. Department of Energy (DOE) and the National Institute of Standards and Technology (NIST). It describes the results of the latest in a series of ERIP evaluation projects that have been completed since 1980. The period of interest is 1980 through 1994. The evaluation is based on data collected in 1995 through mail and telephone surveys of 211 program participants, and historical data collected during previous evaluations for an additional 253 participants. As of September 1993, a total of 609 inventions had been recommended to DOE by NIST, which screens all submitted inventions for technical merit, potential for commercial success, and potential energy impact. By the end of 1994, at least 144 (or 24%) of these inventions had entered the market, generating total cumulative sales of $961 million (in 19944). It is estimated that in 1994 ERIP inventors earned royalties of $2.3 million, and over the lifetime of the program, royalties total $28.2 million. With $47.5 million in grants awarded from 1975 through 1994 and $124 million in program appropriations over the same period, ERIP has generated a 20:1 return in terms of sales values to grants, and an 8:1 return in sales versus program appropriations. Further, it is estimated that at least 757 job-years of employment were supported by ERIP technologies in 1994, and that this resulted in a return of approximately $3.4 million in individual income taxes to the U.S. Treasury. Finally, approximately $334 million of energy expenditures were saved in 1994 as a result of the commercial success of five ERIP projects. These energy savings resulted in reduced emissions of 2.1 million metric tons of carbon in 1994 alone.

The influence of the directional energy distribution on the nonlinear dispersion relation in a random gravity wave field

Science.gov (United States)

Huang, N. E.; Tung, C.-C.

1977-01-01

The influence of the directional distribution of wave energy on the dispersion relation is calculated numerically using various directional wave spectrum models. The results indicate that the dispersion relation varies both as a function of the directional energy distribution and the direction of propagation of the wave component under consideration. Furthermore, both the mean deviation and the random scatter from the linear approximation increase as the energy spreading decreases. Limited observational data are compared with the theoretical results. The agreement is favorable.

The relation between energy efficiency and other general objectives from a socioeconomic perspective

International Nuclear Information System (INIS)

Ankarhem, Mattias; Braennlund, Runar

2006-09-01

An important question in the analysis of energy efficiency programs and their consequences is: How are objectives and instruments defined? E.g. if the objective is reduced carbon dioxide emissions and energy efficiency is the means to reach the objective, then it is not certain that increased energy efficiency will give the result as expected (1). Furthermore, energy efficiency measures will probably be an inefficient way of reaching the goal (2). (1) due to the rebound effects, and (2) since the measures are applied indiscriminately, energy use with only weak couplings to the objective are also affected. Energy efficiency is a partial and relative measure, and does not give much information studied in isolation. It should rather be studied from the perspective of total resource efficiency. Economic policy ought to have the goal of securing a socioeconomic exploitation of all resources (of which energy is one). An instrument working in this direction is internalizing of external effects e.g. through environmental taxes, so that the prices reflect the socioeconomic costs for using the resources. Early foreign studies indicates that a rebound effect exists, usually, however, the technological efficiency potentials can be realized. In a recent study of Swedish conditions, the rebound effect seems to be important. It totally negates the initial effect, at in the end the emissions have increased compared to the starting point. The results show the energy efficiency measures can be in direct conflict with climate and other environmental objectives.

Augmentation and imparting of knowledge - an essential prerequisite for the further development of energy-related structures

Energy Technology Data Exchange (ETDEWEB)

Schnell, P; Dehli, M [Energie-Versorgung Schwaben A.G., Stuttgart (Germany, F.R.)

1980-01-01

An increasing world energy demand is confronted in future by an only restructed availability of important energy carriers; there are thus signs of considerable disturbances in the world energy supply. In order to solve future problems of energy economy, specific energy knowledge has to be effectfully increased and transmitted. After considering the attitude of the arts and psychology in relation to the natural forces, the authors show that knowledge expansion and transmission are of importance beyond various specific energy areas of research, development and economy; they have to be included meaningfully into the areas of publicity, politics, education and training as well as the public media. Finally, the expansion of international co-operation at the transfer of energy-specific information is of essential importance.

Input-output relation and energy efficiency in the neuron with different spike threshold dynamics.

Yi, Guo-Sheng; Wang, Jiang; Tsang, Kai-Ming; Wei, Xi-Le; Deng, Bin

2015-01-01

Neuron encodes and transmits information through generating sequences of output spikes, which is a high energy-consuming process. The spike is initiated when membrane depolarization reaches a threshold voltage. In many neurons, threshold is dynamic and depends on the rate of membrane depolarization (dV/dt) preceding a spike. Identifying the metabolic energy involved in neural coding and their relationship to threshold dynamic is critical to understanding neuronal function and evolution. Here, we use a modified Morris-Lecar model to investigate neuronal input-output property and energy efficiency associated with different spike threshold dynamics. We find that the neurons with dynamic threshold sensitive to dV/dt generate discontinuous frequency-current curve and type II phase response curve (PRC) through Hopf bifurcation, and weak noise could prohibit spiking when bifurcation just occurs. The threshold that is insensitive to dV/dt, instead, results in a continuous frequency-current curve, a type I PRC and a saddle-node on invariant circle bifurcation, and simultaneously weak noise cannot inhibit spiking. It is also shown that the bifurcation, frequency-current curve and PRC type associated with different threshold dynamics arise from the distinct subthreshold interactions of membrane currents. Further, we observe that the energy consumption of the neuron is related to its firing characteristics. The depolarization of spike threshold improves neuronal energy efficiency by reducing the overlap of Na(+) and K(+) currents during an action potential. The high energy efficiency is achieved at more depolarized spike threshold and high stimulus current. These results provide a fundamental biophysical connection that links spike threshold dynamics, input-output relation, energetics and spike initiation, which could contribute to uncover neural encoding mechanism.

Full-dimensional analytic potential energy surfaces based on CCSD(T)/cc-pVTZ calculations have been determined for 48 small combustion-related molecules. The analytic surfaces have been used in Diffusion Monte Carlo calculations of the anharmonic zero-point energies. The resulting anharmonicity corrections are compared to vibrational perturbation theory results based both on the same level of electronic structure theory and on lower-level electronic structure methods (B3LYP and MP2).

Factor Decomposition Analysis of Energy-Related CO2 Emissions in Tianjin, China

Directory of Open Access Journals (Sweden)

Zhe Wang

2015-07-01

Full Text Available Tianjin is the largest coastal city in northern China with rapid economic development and urbanization. Energy-related CO2 emissions from Tianjin’s production and household sectors during 1995–2012 were calculated according to the default carbon-emission coefficients provided by the Intergovernmental Panel on Climate Change. We decomposed the changes in CO2 emissions resulting from 12 causal factors based on the method of Logarithmic Mean Divisia Index. The examined factors were divided into four types of effects: energy intensity effect, structure effect, activity intensity effect, scale effect and the various influencing factors imposed differential impacts on CO2 emissions. The decomposition outcomes indicate that per capita GDP and population scale are the dominant positive driving factors behind the growth in CO2 emissions for all sectors, while the energy intensity of the production sector is the main contributor to dampen the CO2 emissions increment, and the contributions from industry structure and energy structure need further enhancement. The analysis results reveal the reasons for CO2 emission changes in Tianjin and provide a solid basis upon which policy makers may propose emission reduction measures and approaches for the implementation of sustainable development strategies.

Three empirical essays on consumer behavior related to climate change and energy

Science.gov (United States)

Jacobsen, Grant Douglas

This dissertation consists of three essays. All of the chapters address a topic in the area of household and consumer behavior related to climate change or energy. The first chapter is titled "The Al Gore Effect: An Inconvenient Truth and Voluntary Carbon Offsets". This chapter examines the relationship between climate change awareness and household behavior by testing whether Al Gore's documentary An Inconvenient Truth caused an increase in the purchase of voluntary carbon offsets. The analysis shows that in the two months following the film's release, zip codes within a 10-mile radius of a zip code where the film was shown experienced a 50 percent relative increase in the purchase of voluntary carbon offsets. The second chapter is titled "Are Building Codes Effective at Saving Energy? Evidence from Residential Billing Data in Florida". The analysis shows that Florida's energy-code change that took effect in 2002 is associated with a 4-percent decrease in electricity consumption and a 6-percent decrease in natural-gas consumption in Gainesville, FL. The estimated private payback period for the average residence is 6.4 years and the social payback period ranges between 3.5 and 5.3 years. The third chapter in this dissertation is titled "Do Environmental Offsets Increase Demand for Dirty Goods? Evidence from Residential Electricity Demand". This study evaluates the relationship between green products and existing patterns of consumer behavior by examining the relationship between household enrollment in a green electricity program and consumption of residential electricity. The results suggest there are two different types of green consumers. One type makes a small monthly donation and partially views the donation as a substitute for a previously existing pattern of green behavior, in this case, energy conservation. The other type makes a larger monthly donation and views the donation as a way to make strictly additional improvements in environmental quality.

Relations between Russia and Europe from the perspective of energy strategy

2008-02-15

After the Cold War, Russia and the EU made great improvements in their economic ties and political contacts. However, differences in ideology, geopolitics and so forth still exist, making the relationship between Russia and Europe more and more complex and changeable. On the one hand, the Western world maintains a policy of containment toward Russia. Moreover, NATO and the Dual Eastern Expansion of the EU impose direct pressure on Russia's traditional sphere of strategic influence. On the other hand, Russia is recovering from the ruins of the disintegration of the Soviet Union and actively engaging in military and energy diplomacy, trying to return to great power status by way of its own asymmetric advantages in resources. Because of this resource strategy, energy plays an indispensable role for the evolution process of bilateral relations. (orig.)

Household lifestyle, energy related practices and perceptions of energy efficiency: Evidence from Kitwe, Zambia

Directory of Open Access Journals (Sweden)

Lilias Makashini

2014-08-01

Full Text Available Southern Africa is noted for not only constant power shortages but also poor access to electricity. In Zambia, for example, 75% of the population does not have access to electricity. This is partly because although Zambia has one of the lowest energy tariffs in Southern Africa, when compared with household monthly income, the resource is still reasonably unaffordable. Therefore, there is need to find innovative ways of reducing energy cost. Recent studies have indicated that there are patterns that show that there is a relationship between households' lifestyles and energy consumption. This means that understanding household lifestyles and how that impacts on energy use would be crucial in helping occupants to change their behaviours. This would result in the minimisation of energy consumption and thus a reduction in energy bills. However, there is a dearth of scholarly literature about households' lifestyles and their impacts on energy consumption in most developing countries including Zambia. This study investigates the perceptions of different lifestyles on household energy consumption and knowledge about energy efficiency in the city of Kitwe, the second largest city in Zambia. Motivation and barriers to energy efficiency have also been investigated. To achieve this, a mixed research approach was adopted. Firstly, a quantitative closed structured questionnaire instrument was used to collect data from 59 households in Kitwe. Secondly, mini-focus group discussions (average size of 5 ― brought about by the curiosity of residents and hence the contribution as families per household ― were undertaken in the informal settlement. The major findings are that households are generally motivated to implement energy saving strategies like covering pots when cooking, switching off lights in rooms that are not in use and that more information is needed as lack of knowledge and ‘landlord control' were identified as some of the barriers to energy

Big Bath as a Determinant of Creative Accounting in Small and Micro Enterprises

Directory of Open Access Journals (Sweden)

Lenka Zemánková

2015-01-01

Full Text Available Creative accounting is a 21st century phenomenon and in the context of the economic crisis and deficit budget it has been receiving increasing attention, in particular in the area of prevention and detection of accounting manipulation. The focus of the research on small and micro-enterprises stems from little attention paid to these enterprises and the undeniable importance of small and micro-enterprises for the economy. Primary research is based on the examination of a phenomenological paradigm, i.e. it focuses on understanding human behaviour on the basis of a reference framework for research participants. The main research method used in research is a comparative case study, which is one of few methods that allow research of this sensitive topic. Research will focus on the existence of a big bath in the company’s ratio of profit and turnover as a determinant of a change in the company’s approach to creative accounting.

Patterns of daily energy management at work: relations to employee well-being and job characteristics.

Kinnunen, Ulla; Feldt, Taru; de Bloom, Jessica; Korpela, Kalevi

2015-11-01

The present study aimed at identifying subgroups of employees with similar daily energy management strategies at work and finding out whether well-being indicators and job characteristics differ between these subgroups. The study was conducted by electronic questionnaire among 1122 Finnish employees. First, subgroups of employees with unique and distinctive patterns of energy management strategies were identified using latent profile analysis. Second, differences in well-being indicators and job characteristics between the subgroups were investigated by means of ANCOVA. Four subgroups (i.e., patterns) were identified and named: Passives (n = 371), Averages (n = 390), Casuals (n = 272) and Actives (n = 89). Passives used all three (i.e., work-related, private micro-break and physical micro-break) strategies less frequently than other subgroups, whereas Actives used work-related and physical energy management strategies more frequently than other subgroups. Averages used all strategies on an average level. Casuals' use of all strategies came close to that of Actives, notably in a shared low use of private micro-break strategies. Active and Casual patterns maintained vigor and vitality. Autonomy and social support at work played a significant role in providing opportunities for the use of beneficial energy management strategies. Autonomy and support at work seem to support active and casual use of daily energy management, which is important in staying energized throughout the working day.

Special charges related to household energy use. Documentations 1970-2012; Saeravgifter relatert til husholdningenes energiforbruk

This paper provides an overview of special charges related to household energy use in Norway from 1970 to 2012. Excise duties are presented by the object they apply (rather than to describe the fee arrangements separately). Moreover, they are categorized into three groups: tax on stationary energy, taxes on mobile purposes relating to the ownership and usage-dependent charges on mobile applications. Chapter 2 collects taxes in the first category. The author describes the special taxes imposed on households' stationary energy, such as heating the home. Chapter 3 discusses the various fees imposed on the owner of the vehicle, and how these fees are independent of the amount of transport used. Chapter 4 describes the history of usage-dependent charges on mobile purposes, which include taxes on fuel. This paper is intended to be an encyclopedia for use in future analyzes of the Special Tax behavioral effects in Norwegian households. It is first and foremost in the project households respond to energy and environmental policy measures, funded by the Research Council of the project is not only to look at the excise taxes separately but also how various energy and environmental policy instruments work together. This is one of the reasons for the division of special taxes that have been made in the note. Household energy use contributes to a significant proportion of greenhouse gas emissions and a reduction in household energy consumption is an important goal of climate policy. A number of policy instruments have been eager cat to move household energy consumption away from fossil fuels to renewable energy and increase energy efficiency in Norwegian homes. To ensure the effectiveness of current and future policies, and minimize adverse behavioral effects, information from analyzes of several means changing household adaptation would be of great importance.

Range-energy relations and stopping power of water, water vapour and tissue equivalent liquid for α particles over the energy range 0.5 to 8 MeV

International Nuclear Information System (INIS)

Palmer, R.B.J.; Akhavan-Rezayat, Ahmad

1978-01-01

Experimental range-energy relations are presented for alpha particles in water, water vapour and tissue equivalent liquid at energies up to 8 MeV. From these relations differential stopping powers are derived at 0.25 MeV energy intervals. Consideration is given to sources of error in the range-energy measurements and to the uncertainties that these will introduce into the stopping power values. The ratio of the differential stopping power of muscle equivalent liquid to that of water over the energy range 0.5 to 7.5 MeV is discussed in relation to the specific gravity and chemical composition of the muscle equivalent liquid. Theoretical molecular stopping power calculations based upon the Bethe formula are also presented for water. The effect of phase upon the stopping power of water is discussed. The molecular stopping power of water vapour is shown to be significantly higher than that of water for energies below 1.25 MeV and above 2.5 MeV, the ratio of the two stopping powers rising to 1.39 at 0.5 MeV and to 1.13 at 7.0 MeV. Stopping power measurements for other liquids and vapours are compared with the results for water and water vapour and some are observed to have stopping power ratios in the vapour and liquid phases which vary with energy in a similar way to water. It is suggested that there may be several factors contributing to the increased stopping power of liquids. The need for further experimental results on a wider range of liquids is stressed

Quantum vacuum energy in general relativity

2018-02-15

The paper deals with the scale discrepancy between the observed vacuum energy in cosmology and the theoretical quantum vacuum energy (cosmological constant problem). Here, we demonstrate that Einstein's equation and an analogy to particle physics leads to the first physical justification of the so-called fine-tuning problem. This fine-tuning could be automatically satisfied with the variable cosmological term Λ(a) = Λ{sub 0} + Λ{sub 1}a{sup -(4-ε)}, 0 < ε << 1, where a is the scale factor. As a side effect of our solution of the cosmological constant problem, the dynamical part of the cosmological term generates an attractive force and solves the missing mass problem of dark matter.

Towards sustainable energy systems: The related role of hydrogen

International Nuclear Information System (INIS)

Hennicke, Peter; Fischedick, Manfred

2006-01-01

The role of hydrogen in long run sustainable energy scenarios for the world and for the case of Germany is analysed, based on key criteria for sustainable energy systems. The possible range of hydrogen within long-term energy scenarios is broad and uncertain depending on assumptions on used primary energy, technology mix, rate of energy efficiency increase and costs degression ('learning effects'). In any case, sustainable energy strategies must give energy efficiency highest priority combined with an accelerated market introduction of renewables ('integrated strategy'). Under these conditions hydrogen will play a major role not before 2030 using natural gas as a bridge to renewable hydrogen. Against the background of an ambitious CO 2 -reduction goal which is under discussion in Germany the potentials for efficiency increase, the necessary structural change of the power plant system (corresponding to the decision to phase out nuclear energy, the transformation of the transportation sector and the market implementation order of renewable energies ('following efficiency guidelines first for electricity generation purposes, than for heat generation and than for the transportation sector')) are analysed based on latest sustainable energy scenarios

International Nuclear Information System (INIS)

Lauer, R.; Slaughter, A.J.; Wolin, E.

1987-01-01

This paper presents the design and initial implementation of software which uses a relational database management system for storage and retrieval of real and Monte Carlo generated events from a charm and beauty spectrometer with a vertex detector. The purpose of the software is to graphically display and interactively manipulate the events, fit tracks and vertices and calculate physics quantities. The INGRES database forms the core of the system, while the DI3000 graphics package is used to plot the events. The paper introduces relational database concepts and their applicability to high energy physics data. It also evaluates the environment provided by INGRES, particularly its usefulness in code development and its Fortran interface. Specifics of the database design we have chosen are detailed as well.

Full Text Available Abstract Background Insight in children's energy balance-related behaviours (EBRBs and their determinants is important to inform obesity prevention research. Therefore, reliable and valid tools to measure these variables in large-scale population research are needed. Objective To examine the test-retest reliability and construct validity of the child questionnaire used in the ENERGY-project, measuring EBRBs and their potential determinants among 10-12 year old children. Methods We collected data among 10-12 year old children (n = 730 in the test-retest reliability study; n = 96 in the construct validity study in six European countries, i.e. Belgium, Greece, Hungary, the Netherlands, Norway, and Spain. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC and percentage agreement comparing scores from two measurements, administered one week apart. To assess construct validity, the agreement between questionnaire responses and a subsequent face-to-face interview was assessed using ICC and percentage agreement. Results Of the 150 questionnaire items, 115 (77% showed good to excellent test-retest reliability as indicated by ICCs > .60 or percentage agreement ≥ 75%. Test-retest reliability was moderate for 34 items (23% and poor for one item. Construct validity appeared to be good to excellent for 70 (47% of the 150 items, as indicated by ICCs > .60 or percentage agreement ≥ 75%. From the other 80 items, construct validity was moderate for 39 (26% and poor for 41 items (27%. Conclusions Our results demonstrate that the ENERGY-child questionnaire, assessing EBRBs of the child as well as personal, family, and school-environmental determinants related to these EBRBs, has good test-retest reliability and moderate to good construct validity for the large majority of items.

Free energy of activation. Definition, properties, and dependent variables with special reference to linear free energy relations

International Nuclear Information System (INIS)

Levine, R.D.

1979-01-01

The reaction rate constant is expressed as Z exp(-G/sub a//RT). Z is the binary collision frequency. G/sub a/, the free energy of activation, is shown to be the difference between the free energy of the reactive reactants and the free energy of all reactants. The results are derived from both a statistical mechanical and a collision theoretic point of view. While the later is more suitable for an ab-initio computation of the reaction rate, it is the former that lends itself to the search of systematics and of correlations and to compaction of data. Different thermodynamic-like routes to the characterization of G/sub a/ are thus explored. The two most promising ones appear to be the use of thermodynamic type cycles and the changes of dependent variables using the Legendre transform technique. The dependence of G/sub a/ on ΔG 0 , the standard free energy change in the reaction, is examined from the later point of view. It is shown that one can rigorously express this dependence as G/sub a/ = αΔG 0 + G/sub a/ 0 M(α). Here α is the Bronsted slope, α = -par. delta ln k(T)/par. delta(ΔG 0 /RT), G/sub a/ 0 is independent of ΔG 0 and M(α), the Legendre transform of G/sub a/, is a function only of α. For small changes in ΔG 0 , the general result reduces to the familiar ''linear'' free energy relation delta G/sub a/ = α delta ΔG 0 . It is concluded from general considerations that M(α) is a symmetric, convex function of α and hence that α is a monotonically increasing function of ΔG 0 . Experimental data appear to conform well to the form α = 1/[1 + exp(-ΔG 0 /G/sub s/ 0 )]. A simple interpretation of the ΔG 0 dependence of G/sub a/, based on an interpolation of the free energy from that of the reagents to that of the products, is offered. 4 figures, 69 references

Most studies that aim to understand the interactions between different types of photon radiation and cellular DNA assume homogeneous cell irradiation, with all cells receiving the same amount of energy. The level of DNA damage is therefore generally determined by averaging it over the entire population of exposed cells. However, evaluating the molecular consequences of a stochastic phenomenon such as energy deposition of ionizing radiation by measuring only an average effect may not be sufficient for understanding some aspects of the cellular response to this radiation. The variance among the cells associated with this average effect may also be important for the behaviour of irradiated tissue. In this study, we accurately estimated the distribution of the number of radiation-induced γH2AX foci (RIF) per cell nucleus in a large population of endothelial cells exposed to 3 macroscopic doses of gamma rays from 60Co. The number of RIF varied significantly and reproducibly from cell to cell, with its relative standard deviation ranging from 36% to 18% depending on the macroscopic dose delivered. Interestingly, this relative cell-to-cell variability increased as the dose decreased, contrary to the mean RIF count per cell. This result shows that the dose effect, in terms of the number of DNA lesions indicated by RIF is not as simple as a purely proportional relation in which relative SD is constant with dose. To analyse the origins of this observed variability, we calculated the spread of the specific energy distribution for the different target volumes and subvolumes in which RIF can be generated. Variances, standard deviations and relative standard deviations all changed similarly from dose to dose for biological and calculated microdosimetric values. This similarity is an important argument that supports the hypothesis of the conservation of the association between the number of RIF per nucleus and the specific energy per DNA molecule. This comparison allowed us to

Investigating Theoretical PV Energy Generation Patterns with Their Relation to the Power Load Curve in Poland

Directory of Open Access Journals (Sweden)

Jakub Jurasz

2016-01-01

Full Text Available Polish energy sector is (almost from its origin dominated by fossil fuel feed power. This situation results from an abundance of relatively cheap coal (hard and lignite. Brown coal due to its nature is the cheapest energy source in Poland. However, hard coal which fuels 60% of polish power plants is picking up on prices and is susceptible to the coal imported from neighboring countries. Forced by the European Union (EU regulations, Poland is struggling at achieving its goal of reaching 15% of energy consumption from renewable energy sources (RES by 2020. Over the year 2015, RES covered 11.3% of gross energy consumption but this generation was dominated by solid biomass (over 80%. The aim of this paper was to answer the following research questions: What is the relation of irradiation values to the power load on a yearly and daily basis? and how should photovoltaics (PV be integrated in the polish power system? Conducted analysis allowed us to state that there exists a negative correlation between power demand and irradiation values on a yearly basis, but this is likely to change in the future. Secondly, on average, daily values of irradiation tend to follow power load curve over the first hours of the day.

The ISET ended the 10th anniversary year since its foundation in 1998 with already the third Kassel symposium on energy-related system engineering: renewable energy sources and rational energy use. Covering several special subjects talks were given about the topics modelling and simulation in the fields of wind energy, photovoltaic systems, hybrid systems or sewage water treatment. The keen interest of the participants shows the importance that modelling of conditions or processes has gained in the meantime in the field of system engineering of renewable energy sources. The core of each simulation is the integration of differential equations, which describe the system. Properties of the system can be easily varied and affects on the overall system can be easily investigated. Critical conditions can be discovered and be taken into consideration at the hardware engineering. Mistakes in terms of component design can be avoided and engineering cost can be reduced considerably. The present conference book gives an ideal overview of the topics discussed during the symposium. (orig.)

Juan Gabriel Vanegas López

2012-12-01

Full Text Available The diffusion and penetration of energy efficiency measures have positive impacts on both the competitiveness and the security conditions in which firms operate. However, these impacts are difficult to achieve in practice due to the presence of barriers that limit the decision-making process by economic agents. This research identifies, evaluates, and ranks a number of barriers to the efficient use of energy in the microenterprises of Medellín (Colombia. We used the Analytic Hierarchy Process method, finding that the absence of incentives, the high initial investment costs, the lack of knowledge and information by managers, the lack of availability of efficient equipment, and the technical risks are the main constraints. Some strategies to offset their impact highlight that information must respond to the specific context to be effective, economic instruments must account for pricing and financial incentives, and regulations must deal with establishing standards to improve technological parameters.

The text describes, taking reference to a rich stock of data it carries, the nature, politics and economy, demand for energy, policy toward new energy, for each of the host countries. In the European countries, with the exception of France, efforts are being exerted to introduce new energy and to enhance its application, renewable energy in particular, in place of atomic power. The expectation they entertain toward new energy is far extensive than that of Japan which retains atomic power generation. Although wind power generation enjoys the overwhelming popularity over others, yet, in Germany and Sweden, it will be difficult for this technology to take the place of atomic power generation completely. As for photovoltaic power generation, not so much is expected from this technology as in Japan because of their climate and weather. 67 figs., 10 tabs.

This report provides information on the recent commercial progress of inventions supported by the US Department of Energy's Energy-Related Inventions Programs (ERIP). It describes the results of the latest in a series of ERIP evaluation projects that have been completed since 1980. It focuses on the economic impacts of the program, notably sales and employment benefits. The period of interest is 1980 through 1990. The evaluation is based on data collected through mail and telephone surveying of 143 participants in the Program. As of October 1989, a total of 486 inventions were recommended to DOE by the National Institute for Standards and Technology, which screens all submitted inventions in terms of technical merit, potential for commercial success, and potential energy impact. By the end of 1990, at least 109 of these inventions had entered the market, generating total cumulative sales of more than $500 million. With $25.7 million in grants awarded from 1975 through 1990, and $63.1 million in program appropriations over the same period, ERIP has generated a 20:1 return in terms of sales values to grants, and an 8:1 return in sales versus program appropriations. It is estimated that 25% of all ERIP inventions had achieved sales by the end of 1990. While it is difficult to make exact comparisons between these percentages and other indicators of the success rates of technological innovations as a whole, the ERIP figures remain impressive. The commercial progress of spin-off technologies is also documented.

Modeling of energy consumption and related GHG (greenhouse gas) intensity and emissions in Europe using general regression neural networks

Antanasijević, Davor; Pocajt, Viktor; Ristić, Mirjana; Perić-Grujić, Aleksandra

2015-01-01

This paper presents a new approach for the estimation of energy-related GHG (greenhouse gas) emissions at the national level that combines the simplicity of the concept of GHG intensity and the generalization capabilities of ANNs (artificial neural networks). The main objectives of this work includes the determination of the accuracy of a GRNN (general regression neural network) model applied for the prediction of EC (energy consumption) and GHG intensity of energy consumption, utilizing general country statistics as inputs, as well as analysis of the accuracy of energy-related GHG emissions obtained by multiplying the two aforementioned outputs. The models were developed using historical data from the period 2004–2012, for a set of 26 European countries (EU Members). The obtained results demonstrate that the GRNN GHG intensity model provides a more accurate prediction, with the MAPE (mean absolute percentage error) of 4.5%, than tested MLR (multiple linear regression) and second-order and third-order non-linear MPR (multiple polynomial regression) models. Also, the GRNN EC model has high accuracy (MAPE = 3.6%), and therefore both GRNN models and the proposed approach can be considered as suitable for the calculation of GHG emissions. The energy-related predicted GHG emissions were very similar to the actual GHG emissions of EU Members (MAPE = 6.4%). - Highlights: • ANN modeling of GHG intensity of energy consumption is presented. • ANN modeling of energy consumption at the national level is presented. • GHG intensity concept was used for the estimation of energy-related GHG emissions. • The ANN models provide better results in comparison with conventional models. • Forecast of GHG emissions for 26 countries was made successfully with MAPE of 6.4%

2016-08-01

The Urban Heat Island (UHI) is an adverse environmental effect of urbanization that increases the energy demand of cities, impacts the human health, and intensifies and prolongs heatwave events. To facilitate the study of UHIs the Institute for Astronomy, Astrophysics, Space Applications and Remote Sensing of the National Observatory of Athens (IAASARS/NOA) has developed an operational real-time system that exploits remote sensing image data from Meteosat Second Generation - Spinning Enhanced Visible and Infrared Imager (MSG-SEVIRI) and generates high spatiotemporal land surface temperature (LST) and 2 m air temperature (TA) time series. These datasets form the basis for the generation of higher value products and services related to energy demand and heat-related health issues. These products are the heatwave hazard (HZ); the HUMIDEX (i.e. an index that describes the temperature felt by an individual exposed to heat and humidity); and the cooling degrees (CD; i.e. a measure that reflects the energy needed to cool a building). The spatiotemporal characteristics of HZ, HUMIDEX and CD are unique (1 km/5 min) and enable the appraisal of the spatially distributed heat related health risk and energy demand of cities. In this paper, the real time generation of the high spatiotemporal HZ, HUMIDEX and CD products is discussed. In addition, a case study corresponding to Athens' September 2015 heatwave is presented so as to demonstrate their capabilities. The overall aim of the system is to provide high quality data to several different end users, such as health responders, and energy suppliers. The urban thermal monitoring web service is available at http://snf-652558.vm.okeanos.grnet.gr/treasure/portal/info.html.
