The energy sector in Italy, as in Europe and in many other areas of the world, is undergoing rapid and profound changes. The 1986 ratification of the European Single Act was intended to create a European internal market, where circulation of people, capital, goods, and services would reach the highest possible liberalization. In 1988, in the document The Energy Internal Market, the European Union (EU) commission stressed the need for creation of an internal energy market--free of obstacles--to increase security of supply, to reduce costs, and to strengthen the competitiveness of the European economic system. In 1990, the Community Council adopted directives to implement the EU energy sector. This article describes Italy's role as part of the EU energy sector. It covers the following topics: the Italian energy sector; electricity vs gas transportation; project finance; recent developments advance Italian power industry; specifying powerplant components -- Italian stype; buyers' guide to Italian equipment, services

Full Text Available The death of the President of Uzbekistan Islam Karimov, an official announcement which appeared in the second half of the day September 2 - involuntarily forced to wonder about his successor and most importantly, about the continuity of the course. Externally, in the country there is peace and order. Islam Karimov has built a stable system, authoritarian regime. This stability is due to the pragmatism of the Uzbek members of the junta. A special role in the economy and politics of Uzbekistan plays a clan system which has evolved over the last 100-120 years according to the territorial principle and immigrants, which today represent the political elite of the country. The article examines Elite struggle and the stability of the political regime in Uzbekistan available today.

Full Text Available BACKGROUND: Hib vaccine has gradually been introduced into more and more countries during the past two decades, partly due to GAVI Alliance support to low-income countries. However, since Hib disease burden is difficult to establish in settings with limited diagnostic capacities and since the vaccine continues to be relatively expensive, some Governments remain doubtful about its value leading to concerns about financial sustainability. Similarly, several middle-income countries have not introduced the vaccine. The aim of this study is to estimate and compare the cost-effectiveness of Hib vaccination in a country relying on self-financing (Belarus and a country eligible for GAVI Alliance support (Uzbekistan. METHODS AND FINDINGS: A decision analytic model was used to estimate morbidity and mortality from Hib meningitis, Hib pneumonia and other types of Hib disease with and without the vaccine. Treatment costs were attached to each disease event. Data on disease incidence, case fatality ratios and costs were primarily determined from national sources. For the Belarus 2009 birth cohort, Hib vaccine is estimated to prevent 467 invasive disease cases, 4 cases of meningitis sequelae, and 3 deaths, while in Uzbekistan 3,069 invasive cases, 34 sequelae cases and 341 deaths are prevented. Estimated costs per discounted DALY averted are US$ 9,323 in Belarus and US$ 267 in Uzbekistan. CONCLUSION: The primary reason why the cost-effectiveness values are more favourable in Uzbekistan than in Belarus is that relatively more deaths are averted in Uzbekistan due to higher baseline mortality burden. Two other explanations are that the vaccine price is lower in Uzbekistan and that Uzbekistan uses a three dose schedule compared to four doses in Belarus. However, when seen in the context of the relative ability to pay for public health, the vaccine can be considered cost-effective in both countries.

Assessing future water requirements for feeding the growing population of Central Asia can improve understanding of the projected water supply scenarios in the region. Future water requirements will be partially determined by the dietary habits of the populations, and are thus responsive to significant variation of income levels. Using Uzbekistan as an example, this study projects the water footprints of income driven changes on the population's diet in Central Asia. To reveal the influence of large income changes on dietary habits a Normalized Quadratic-Quadratic Expenditure System was calibrated and applied to data from 2009. The national water footprints of food consumption in Uzbekistan were projected until 2034 by applying the parameterized demand system to estimate the respective water footprint values. The results showed that for Uzbekistan the projected increase in the food consumption water footprint would be primarily linked to income growth rather than population growth. Due to the high water footprint of common food products, the composition of the population's diet, and responsiveness to income, economic growth is expected to put greater pressure on water resources in Uzbekistan unless proper measures are undertaken.

Full text: Spent nuclear fuel containing enough uranium to produce 2.5 nuclear weapons has been safely returned to Russia from Uzbekistan in a classified mission completed on 19 April 2006. It is the first time that fuel used in a nuclear research reactor - referred to as 'spent' - has been repatriated to Russia since the break-up of the Soviet Union. Under tight security, 63 kilograms of spent highly enriched uranium (HEU) was transported to Mayak in Russia, in four separate shipments. IAEA safeguards inspectors monitored and verified the packing of the fuel for transport over the course of 16 days. The secret operation, six years in the planning, was a joint undertaking of the IAEA, the United States, Uzbekistan, Russia and Kazakhstan as part of the Global Threat Reduction Initiative (GTRI). The aim of the GTRI is to identify, secure and recover high-risk vulnerable nuclear and radiological materials around the world. 'There was particular concern about the Uzbek spent fuel given its significant quantity and that it was no longer 'self protecting', 'the IAEA's Crosscutting Co-ordinator for Research Reactors, Mr. Pablo Adelfang, said. 'This means that the fuel has lost its high radioactivity. In other words, it would no longer injure anyone who handled it and would not deter potential thieves,' Mr. Adelfang said. 'The shipment is an important step to reduce stockpiles of high-risk, vulnerable nuclear materials. Russia, the US, Uzbekistan and Kazakhstan should be applauded for their successful cooperation. It will contribute to the security of both Uzbekistan and the international community,' he added. In Russia, the fuel will be processed so that it can not be used for atomic bombs. Russia originally supplied the nuclear fuel to Uzbekistan for use in its 10 megawatt research reactor. Located at the Institute of Nuclear Physics of Uzbekistan, 30 km from Tashkent, the reactor is currently used for research and to produce isotopes for medical purposes. The IAEA is

Power and heating generation sector and transport sector contribute a highest GHG emissions and even air pollutions. This paper seeks to investigate life cycle costs and emissions in both the power sector and transport sector, and evaluate the cost-emission efficient (costs for one unit GHG emissions) of the substitution between new energy vehicles and conventional gasoline based vehicles under two electricity mix scenarios. In power sector, wind power and PV power will be cost comparative in 2030 forecasted with learning curve method. With high subsidies, new energy cars could be comparative now, but it still has high costs to lower GHG emissions. When the government subsidy policy is reversible, the emission reduction cost for new energy vehicle consumer will be 900/ton. According to the sensitive analysis, the paper suggests that the government implement policies that allocate the cost to the whole life cycle of energy production and consumption related to transport sector energy transition and policies that are in favor of new energy vehicle consumers but not the new energy car producers.

Status of the reforms in Lithuania's energy sector and preparation of updated Energy Strategy is presented in this article. The new Strategy has been worked out considering the conclusions of different studies as well as the changes that have taken place in Lithuania and restructuring of its energy sector, the guidelines of the European Union. The principal objectives of the country's energy sector consists in reliable and safe energy supply with minimum expenses, increasing efficiency of energy utilisation, introducing principles of market economy within the sector, reducing environmental impacts, preparing Lithuania's energy sector for integration into the EU. In the field of nuclear energy the top priority is to ensure the safety of Ignalina NPP. Ignalina NPP will only be operated if and as long as it is safe. Two most likely scenarios for the future operation of Ignalina NPP are analysed in the draft Strategy. According to scenario 1, reactor 1 and 2 are to be operated half of the design service life, until 2005 and 2010 respectively, i.e. until the gap between the graphite and fuel channels reaches the critical margin. In accordance with the second scenario, the fuel channels are to be replaced as envisaged in the design, after which the reactors may be operated for another 10 - 15 years

As the world’s top energy consumer, China is facing a great challenge to solve its energy supply issue. In this paper energy use from all industrial sectors in China’s economy of 2007 was explored by conducting an extended environmental input–output analysis. We compare the energy consumption embodied in the final demand for goods and services from 29 sectors with the energy demand required for the actual production process in each sector. Two different viewpoints for sectoral energy use have been presented: energy use is directly allocated to the producer entity, and energy use is reallocated to sector’s supply chain from consumption perspective. Our results show that considerable amount of energy use is embodied in the supply chain, especially for “Construction” and “Other Service Activities” sectors, which is not detected if energy use is allocated on a production basis. When further dividing embodied energy consumption into direct energy consumption and indirect energy consumption, total indirect energy consumption is much higher than that of total direct energy consumption, accounting for 80.6% of total embodied energy consumption in 2007. Our results provide a more holistic picture on sectoral energy consumption and therefore can help decision-makers make more appropriate policies. - Highlights: ► A hybrid IO-LCA model was employed to analyze China’s energy use at sectoral level. ► A case study on China’s sectoral energy consumption is done. ► Construction and service sectors are actually energy intensive from the supply chain perspectives. ► Upstream and downstream ectoral collaboration along the whole supply chain is necessary. ► Energy conservation policies should be based upon a comprehensive analysis on sectoral energy use.

At the present, the State authorities of the Republic of Uzbekistan pay special attention to the development of small and medium businesses and, in particular, to the enterprises oriented on manufacturing products with high added value. The leather and footwear industry of Uzbekistan is one of the dynamically developing sectors of economy. However, the study of the situation demonstrates that the increase in number of small and medium footwear and leather enterprises that have taken place in recent years, is not accompanied by a formation of corresponding professional training system for the enterprises, especially for associate specialists. The analysis of the legal base disclosed that the professional training level in footwear industry enterprises does not meet the up-to-date manufacturing requirements. The study is devoted to the issues of professional training of practice-oriented staff - the specialists for small enterprises of footwear and leather industry. The main task is the development of new vocational courses and programs for the training and professional development of personnel at all levels. The basic stages of complete staff training cycle for footwear sector have been determined based on the practical experience of staff training for small footwear enterprises in Greece. The 3-6 months duration short-term courses recommended for associate and medium level specialists have been developed and evaluated.

Highlights: • A hybrid solar-assisted desalination cycle was designed and stimulated. • Maximum of 21,064.00 kW effective solar heat can be achieved. • The use of parabolic-trough collectors in the Multi Effect Distillation is potential. • The cycle can be applied in other regions with high Direct Normal Irradiation. - Abstract: This study was to investigate possible reduction of fossil fuel consumption and carbon dioxide emission in one of energy sectors of Sirdarya Thermal Power Plant (TPP), Uzbekistan. A hybrid solar-assisted desalination cycle has been designed and simulated for partially supplying saturated steam with 200 °C, 8 bar, and 32 t/h parameters to a Multi Effect Distillation (MED) process in the Sirdarya Thermal Power Plant. The outcome of the parental design model stated that maximum, 21,064.00 kW effective solar heat can be achieved, which is equivalent to 31.76 t/h of saturated steam with 200 °C and 8 bar parameters. Total saved fossil fuel in each month proved that it is possible to reduce fossil fuel (heavy oil and natural gas) consumption with 59.64, 95.24, 389.96, and 298.26 tons during available Direct Normal Irradiation (DNI) by using parabolic-trough collectors. Moreover, the above-mentioned fossil fuel savings accounted for CO_2 reduction with amounts of 182.50, 255.46, 1045.87 & 799.96 tons per each consistent month. Findings proved that integration of parabolic-trough collectors into the MED process is feasible in terms of high DNI availability and demand for retrofitting old existing heat-consuming facilities in Sirdarya Thermal Power Plant. Besides, the cycle also can be applied in other regions of Uzbekistan with high DNI for generating solar heat. Therefore, conducted study is eligible to be applied on the research site by taking into account of sufficient meteorological data and required steam parameters.

How Tight is Too Tight? A Look at Welfare Implications of Distortionary Policies in Uzbekistan

Directory of Open Access Journals (Sweden)

Edward R. Gemayel

2006-12-01

Full Text Available Since independence in 1991, Uzbekistan has pursued a gradual approach to the transition from planned to market economy. This approach relied heavily on trade controls, directed credit, and large public investments. In addition, a number of financial sector measures were instituted that distorted resource allocation and increased transaction costs. As a result, while possibly preventing the contraction of output in the early 1990s, these policies led to disappointing economic outcomes and social conditions later on. The paper reviews the underlying distortions and presents survey-based evidence to support their existence and their detrimental impact on economic activity. Looking forward, the paper - using a representative agent framework to model existing financial sector distortions - offers some guidance regarding the likely implications of eliminating these distortions on key aggregate variables. It suggests that the elimination of these distortions will be welfare enhancing and will lead to higher levels of investment and capital stock.

Gender earnings and poverty reduction: post-Communist Uzbekistan.

Women get less of the material resources, social status, power and opportunities for self-actualization than men do who share their social location – be it a location based on class, race, occupation, ethnicity, religion, education, nationality, or any intersection of these factors. The process of feminization of poverty in Central Asia and Uzbekistan is intimately connected to the cultural and institutional limitations that put a ceiling on women’s involvement in economic activity. This article attempts to study and explore gender in the context of poverty reduction in Uzbekistan, the most populated state of Central Asia, to understand the ways and manner in which poverty and other forms of deprivation demand women’s participation in variety of contexts. The study is primarily an empirical one and is based on an extensive sociological investigation in the field.

Hohmann, Sophie; Garenne, Michel

2010-12-01

The study investigates the magnitude of differences in child and adult mortality by wealth in Uzbekistan, a former soviet country of Central Asia, and compares it with similar indicators from sub-Saharan Africa. Data were derived from Demographic and Health Surveys. An "Absolute Wealth Index" was built from data on goods owned by households and quality of housing, and scaled from 0 to 12. Wealth was distributed evenly in Uzbekistan, with a symmetric distribution around a mean of 5.5 modern goods. In sub-Saharan Africa, on the contrary, the wealth distribution had a lower mean (2.5) and was highly skewed towards the left, revealing a high proportion of very poor people. Adult and child mortality levels were lower in Uzbekistan. Despite these major differences, the relationships between mortality indicators and the wealth index were similar in the two cases. The magnitude of mortality differentials by wealth was of the same order in both cases, with gradients ranging from 2.5 to 1 for child mortality and 1.5 to 1 for adult mortality (poorest versus richest). However, mortality levels remained lower in Uzbekistan than in sub-Saharan Africa at the same level of wealth for both children and adults. A similar relationship was found between nutritional status and wealth index in both cases. On the contrary, there were no differences by wealth in use of health services and level of education in Uzbekistan, whereas wealth gradients were steep for the same variables in sub-Saharan Africa. The study suggests that mortality differentials were primarily due to nutritional status, and not to access and use of health services or to education. The discussion focuses on health and social policies during the colonial and post-colonial period that have produced these patterns. Copyright © 2010 Elsevier B.V. All rights reserved.

Dynamics of final sectoral energy demand and aggregate energy intensity

International Nuclear Information System (INIS)

Lescaroux, Francois

2011-01-01

This paper proposes a regional and sectoral model of global final energy demand. For the main end-use sectors of consumption (industrial, commercial and public services, residential and road transportation), per-capita demand is expressed as an S-shaped function of per-capita income. Other variables intervene as well, like energy prices, temperatures and technological trends. This model is applied on a panel of 101 countries and 3 aggregates (covering the whole world) and it explains fairly well past variations in sectoral, final consumption since the beginning of the 2000s. Further, the model is used to analyze the dynamics of final energy demand, by sector and in total. The main conclusion concerns the pattern of change for aggregate energy intensity. The simulations performed show that there is no a priori reason for it to exhibit a bell-shape, as reported in the literature. Depending on initial conditions, the weight of basic needs in total consumption and the availability of modern commercial energy resources, various forms might emerge. - Research Highlights: → The residential sector accounts for most of final energy consumption at low income levels. → Its share drops at the benefit of the industrial, services and road transportation sectors in turn. → Sectoral shares' pattern is affected by changes in geographic, sociologic and economic factors. → Final energy intensity may show various shapes and does not exhibit necessarily a bell-shape.

Public sector energy management: A strategy for catalyzing energy efficiency in Malaysia

Science.gov (United States)

Roy, Anish Kumar

To date the public sector role in facilitating the transition to a sustainable energy future has been envisaged mainly from a regulatory perspective. In such a role, the public sector provides the push factors---enforcing regulations and providing incentives---to correct market imperfections that impede energy transitions. An alternative and complementary role of the public sector that is now gaining increasing attention is that of catalyzing energy transitions through public sector energy management initiatives. This dissertation offers a conceptual framework to rationalize such a role for the public sector by combining recent theories of sustainable energy transition and public management. In particular, the framework identifies innovative public management strategies (such as performance contracting and procurement) for effectively implementing sustainable energy projects in government facilities. The dissertation evaluates a model of sustainable public sector energy management for promoting energy efficiency in Malaysia. The public sector in Malaysia can be a major player in leading and catalyzing energy efficiency efforts as it is not only the largest and one of the most influential energy consumers, but it also plays a central role in setting national development strategy. The dissertation makes several recommendations on how a public sector energy management strategy can be implemented in Malaysia. The US Federal Energy Management Program (FEMP) is used as a practical model. The analysis, however, shows that in applying the FEMP model to the Malaysian context, there are a number of limitations that will have to be taken into consideration to enable a public sector energy management strategy to be effectively implemented. Overall the analysis of this dissertation contributes to a rethinking of the public sector role in sustainable energy development that can strengthen the sector's credibility both in terms of governance and institutional performance.

Climate change has been shown to increase the number of mountain lakes across various mountain ranges in the World. In Central Asia, and in particular on the territory of Uzbekistan, a detailed assessment of glacier lakes and their evolution over time is, however lacking. For this reason we created the first detailed inventory of mountain lakes of Uzbekistan based on recent (2002-2014) satellite observations using WorldView-2, SPOT5, and IKONOS imagery with a spatial resolution from 2 to 10m. This record was complemented with data from field studies of the last 50years. The previous data were mostly in the form of inventories of lakes, available in Soviet archives, and primarily included localized in-situ data. The inventory of mountain lakes presented here, by contrast, includes an overview of all lakes of the territory of Uzbekistan. Lakes were considered if they were located at altitudes above 1500m and if lakes had an area exceeding 100m 2 . As in other mountain regions of the World, the ongoing increase of air temperatures has led to an increase in lake number and area. Moreover, the frequency and overall number of lake outburst events have been on the rise as well. Therefore, we also present the first outburst assessment with an updated version of well-known approaches considering local climate features and event histories. As a result, out of the 242 lakes identified on the territory of Uzbekistan, 15% are considered prone to outburst, 10% of these lakes have been assigned low outburst potential and the remainder of the lakes have an average level of outburst potential. We conclude that the distribution of lakes by elevation shows a significant influence on lake area and hazard potential. No significant differences, by contrast, exist between the distribution of lake area, outburst potential, and lake location with respect to glaciers by regions. Copyright © 2017 Elsevier B.V.

2013-05-01

Full Text Available BACKGROUND: In 2012, Uzbekistan ratified the Framework Convention on Tobacco Control, which states that price and tax measures are an effective means of reducing tobacco consumption. We aimed to explore the effect of taxation policies on revenues and cigarette consumption. METHODS: Data on tax rates, revenues, cigarette sales were taken from national reports. To forecast potential revenues, a scenario analysis was performed. RESULTS: In 1991-2004, ad valorem excise system was in place in Uzbekistan, which was later replaced by the specific excise system. In 1997-2011, the nominal average excise has increased by a factor of twenty, but in real terms, after a sharp increase in 1999, average excise declined annually and increased only in 2010-2011. Annual cigarette sales per capita of adult population in 1999-2007 constituted 17-25 cigarette packs, while in 2008-2011 it increased to 30-37 packs. Four scenarios of excise tax increases in 2012 were developed: one actual scenario based on the rates effective in Uzbekistan in 2012, and three hypothetical ones anticipating excise rates increase by 1.5, 2 and 3-fold. With actual excise increase in 2012, the inflation-adjusted budget revenues would grow by 5%, and with three hypothetical - by 17%, 35% and 66% respectively, despite the decline of tax-paid cigarette sales. CONCLUSION: Stabilization or reduction in cigarette excises in Uzbekistan in 2002-2008 led to a decline in real excise revenues and the growth of cigarette sales. In 1999 and 2010-2011, excises were significantly increased and the real revenues have risen, despite the decline in cigarette sales. As cigarette prices are low, the illegal outflow of cigarettes from Uzbekistan apparently exceeds the illegal inflow. A significant increase in cigarette excise (1.5-3 fold can both increase budget revenues and reduce cigarette consumption, with greater increase yielding more benefits.

International Nuclear Information System (INIS)

Puksec, T.; Duic, N.

2011-01-01

Households sector in Croatia represents one of the largest consumers of energy today with around 75,75PJ, which is almost 29% of Croatia's final energy demand. Considering this consumption, implementing different mechanisms that would lead to improvements in energy efficiency in this sector seems relevant. In order to plan future energy systems it is important to know future possibilities and needs regarding energy demand for different sectors. Through this paper long term energy demand projections for Croatian households sector will be shown with a special emphasis on different mechanisms, both financial, legal but also technological that will influence future energy demand scenarios. It is important to see how these mechanisms influence, positive or negative, on future energy demand and which mechanism would be most influential. Energy demand predictions in this paper are based upon bottom-up approach model which combines and process large number of input data. The Model will be compared to Croatian national Energy Strategy and certain difference will be presented. One of the major conclusions shown in this paper is significant possibilities for energy efficiency improvements and lower energy demand in the future, based on careful and rational energy planning. Different financial, legal and technological mechanisms can lead to significant savings in the households sector which also leads to lesser greenhouse gas emissions and lower Croatian dependence on foreign fossil fuels.

Uranium is a naturally occurring radioactive metal, and is widely distributed in the Earth's crust. But it is concentrated in certain rock formations. Most of the uranium for nuclear weapon produced in the Soviet Union during the Cold War came from Central Asia. Uranium has negative effects on the human body, both as a carcinogen and as a kidney toxin. WHO (2004) prescribed that uranium concentrations in drinking water should be less than 15 mcg/l for only chemical aspects of uranium addressed. We determined high uranium concentrations in drinking water in the central region of Uzbekistan (Y. KAWABATA et al. 2004). In this area, some discharge water from farmland has higher uranium concentration. Irrigation systems Kyzyl-orda in Republic of Kazakhstan and in Karakalpakstan in the Republic of Uzbekistan have drains deeper than 5 m, in order to protect against salinization. Water in these drains can mix with ground water. In this area, ground water is used for drinking water. We investigated uranium concentrations in water in Kazakhstan and Uzbekistan. In the half of drinking water sampling points, uranium concentrations exceeded the WHO (2004) guideline level for drinking water. Uranium is a suspected carcinogen that can also have a toxic effect on kidney. However, WHO addresses only the chemical aspects of uranium by giving uranium concentrations in drinking water. The effect of uranium exposure from drinking water on people in these areas is significant. The uranium concentration in the Aral Sea was higher than that in sea water. Aral Sea is accumulating uranium. (author)

Khaydarov, R. A.; Khaydarov, R. R.

2007-01-01

Uzbekistan is a checkpoint for transportation between Russia and some Asian countries, such as Iran, Pakistan, Afghanistan and Tajikistan that might be attractive destinations for those smuggling nuclear materials or weapons. Currently there are over 200 border crossing points. Most of them have equipped with monitors able to reliably detect nuclear materials. Uzbekistan also has substantial radioactive ore mining, and these monitors also allow the Customs Service to maintain safe conditions for their inspectors as well as for population of Uzbekistan and its neighbors. But it is very important to detect radioactive materials inland, their location and travel. This task cannot be solved by using stationary detectors which are used at border crossing points. New method, electronic scheme and software for remote detection, location and travel of radioactive sources were developed. The operation principle lies in detection of radiation by 6 detectors situated in a leaden cylindrical shield collimating gamma-radiation in 6 directions. Besides the detection system contains 6 amplifiers, 6 counters and JPS-system connected with computer. The detection system is transported by car. Field tests of the detection system have shown that the detection limit is 5. 106 Bq and 4.106 Bq for Co60 and Cs137 respectively when the radioactive sources distance is 400 m. (author)

Vietnam's energy sector: A review of current energy policies and strategies

International Nuclear Information System (INIS)

Tien Minh Do; Sharma, Deepak

2011-01-01

Since the introduction of market-oriented economy in 1986, Vietnam has made noticeable socio-economic progress. In this progress, the energy sector has played a vital role. This role is likely to deepen in the years to come as Vietnam strives to achieve even higher levels in economic progress. Such deepening in the role of energy, this paper argues, will heighten concerns about the security of energy supply, and economic, environmental, social and political consequences. In order to address these issues, Vietnam has over the last decade, developed a suite of energy policies. A deeper review of these policies suggests that they are typified by economic-growth orientation, exclusive focus on a single-sector or single issue, and largely neglect the significance of cross-sectoral and cross-thematic issues arising from the interdependencies between energy, economy, and the polity at large. The existing energy policy settings are, therefore, unlikely to be able to provide a satisfactory redress to the challenges noted above. This paper provides an overview of the current energy policies with a view to identify areas where further policy effort is needed in order to facilitate a sustainable development of the Vietnamese energy sector. - Highlights: → Identifying challenges faced by the Vietnamese energy sector. → Analyzing limitations of the existing energy policy settings (policies, strategies and institutions) in addressing these challenges. → Developing recommendations on improving the existing energy policy settings to provide a satisfactory redress for the challenges noted above.

Cartel control in the energy sector

International Nuclear Information System (INIS)

Buedenbender, U.

1995-01-01

The current regulatory regime governing the electricity and gas supply industries of the energy sector is characterized by the admissibility of protected sales areas defined by demarcation agreements. However, this economic advantage is counterbalanced by legal provisions providing for specific supervision of the utilities under cartel law. The cartel authority exercises the functions of control of abusive practices, focussing on control of prices and general terms and conditions, cooperation between the utilities and operators owners of power generation plants, the very topical aspects of TPA (third party access to networks), and adherence to the principle of conduct of business of the utilities in line with the conditions of free competition. The book addresses all relevant aspects of cartel control relating to existing law and the overall context of the energy sector. General principles of cartel control in the economic sector at large are compared to specific conditions in the energy sector, revealing the differences in competences of the cartel authority.

Perez-Jacome, D.

1999-01-01

An overview of Mexico's energy sector was presented, with particular focus on the natural gas and electricity sectors. Mexico ranks fifth in oil production, eighth in proven oil reserves, and fourteenth in natural gas reserves. In 1998, the energy sector generated 3.3 per cent of Mexico's gross domestic product (GDP), and oil accounted for 7.5 per cent of total exports. National production of natural gas has been forecasted to grow at a rate of 5.2 per cent annually over the next 10 years. This will be largely due to the increased demand for natural gas to produce electricity. The Mexican government has also taken initiatives to restructure the Mexican energy sector with particular focus on increasing the competitiveness of the electric power industry. Electricity demand is also expected to grow at a rate of 6 per cent annually over the next six years. The objectives of energy reform are to promote more investment from all sectors in order to strengthen the development of the electric power industry and to provide a reliable, high quality service at competitive prices. 9 figs

Sectoral Energy, and Labour, Productivity Convergence

International Nuclear Information System (INIS)

Mulder, P.; De Groot, H.L.F.

2007-01-01

This paper empirically investigates the development of cross-country differences in energy- and labour productivity. The analysis is performed at a detailed sectoral level for 14 OECD countries, covering the period 1970-1997. A ρ-convergence analysis reveals that the development over time of the cross-country variation in productivity performance differs across sectors as well as across different levels of aggregation. Both patterns of convergence as well as divergence are found. Cross-country variation of productivity levels is typically larger for energy than for labour. A β-convergence analysis provides support for the hypothesis that in most sectors lagging countries tend to catch up with technological leaders, in particular in terms of energy productivity. Moreover, the results show that convergence is conditional, meaning that productivity levels converge to country-specific steady states. Energy prices and wages are shown to positively affect energy- and labour-productivity growth, respectively. We also find evidence for the importance of economies of scale, whereas the investment share, openness and specialization play only a modest role in explaining cross-country variation in energy- and labour-productivity growth

Charismatic Routinization and Problems of Post-Charisma Succession in Kazakhstan, Turkmenistan and Uzbekistan

Directory of Open Access Journals (Sweden)

Rico Isaacs

2015-07-01

Full Text Available Using Weber’s concept of charismatic routinisation, this article analyses the dilemmas related to political succession and post-charismatic order in Kazakhstan, Turkmenistan and Uzbekistan. While the presidents of these three countries have drawn their authority from a combination of charismatic, legal-rational and traditional authority, they have relied most heavily on charisma in particular to sustain their rule. With the presidents of Kazakhstan and Uzbekistan aging and facing the question of political succession, the article provides an analysis of the problems associated with potential for post-charismatic succession in these states. It does so by drawing on three of Weber’s mechanisms for charismatic routinisation: designation, hereditary charisma, and charisma in office. The analysis demonstrates that in these three cases, despite charisma only having two routes available to it, traditional and legal-rational, the mixture of legal-rational, traditional and charismatic domination undermines the process of charismatic routinisation. Consequently, the article argues that political succession in Kazakhstan and Uzbekistan will most likely evolve into a reconstitution of charismatic leadership.

This paper analyzes consumer satisfaction in the energy sector in Kenya to assess the quality and level of service delivery. By use of the European Consumer Satisfaction Index (ECSI), the paper estimates consumer satisfaction in biomass, petroleum, electricity and renewable energy subsectors. The findings are that consumer satisfaction is highest in the renewable energy sub sector at 74.7% followed by petroleum at 62.8%. The electricity sub sector has the lowest consumer satisfaction of 53.06%. Further, it is found that the image of renewable energy providers is also the highest at 72.5% followed by that of petroleum companies at 63.1%. In the electricity sub sector, perceived value scored the highest at 64.2%. The paper concludes that image of a service provider, loyalty of consumers, consumer expectations, perceived value, perceived quality and the way complains are handled are very important factors that determine consumer satisfaction levels. It is recommended that for monitoring and evaluation purposes in the performance of the energy sector, the Energy RegulatoryCommission(ERC) could use the consumer satisfaction index level to evaluate whether the regulatory policies and their implementation are bearing fruit where a high index would be associated with good performance and vice versa. - Highlights: ► The paper estimates consumer satisfaction in biomass, petroleum, electricity and renewable energy subsectors. ► Consumer satisfaction is highest in the renewable energy sub sector at 74.7%. ► The electricity sub sector has the lowest consumer satisfaction of 53.06%. ► Image of renewable energy providers is also the highest at 72.5%. ► Factors explaining consumer satisfaction are; Image, consumers’ loyalty, expectations, perceived value, and perceived quality.

Highlights: ► Long term energy demand of Croatian households sector has been modelled. ► Developed model can describe the whole households sector. ► Main modes include heating, cooling, electrical appliances, cooking and hot water. ► Different scenarios regarding future energy demand are presented and discussed. -- Abstract: Households represent one of the most interesting sectors, when analyzing Croatia’s energy balance. It makes up one of the largest energy consumers with around 75 PJ per year, which is almost 29% of Croatia’s final energy demand. Considering this consumption, implementing various mechanisms, which would lead to improvements in energy efficiency of this sector, seems relevant. In order to plan future energy systems, important would be to know future possibilities and needs regarding energy demand of different sectors. Through this paper, long term energy demand projections of Croatian households sector will be shown. Focus of the paper will be on various mechanisms influencing future energy demand scenarios. Important would be to quantify this influence, whether positive or negative, and see which mechanisms would be the most significant. Energy demand projections in this paper are based upon bottom-up approach model which combines and processes a large number of input data. The model will be compared to Croatian National Energy Strategy and certain differences and conclusions will be presented. One of the major conclusions shown in this paper is significant possibilities for energy efficiency improvements and lower energy demand in the future, based on careful and rational energy planning. Different financial, legal and technological mechanisms can lead to significant savings in the households sector which leads to lower GHG emissions and lower Croatian dependence on foreign fossil fuels.

In the modern world the waves of terrorism spreading into international level the fight against has become one of most important tasks, in particular for Uzbekistan. Uzbekistan is geographically located at the crossroads from Europe (Western Europe, Russia) to Asia (Turkmenistan, Iran, Afghanistan, Pakistan and further to the South) and its territory is one of the possible routes for illegal transportation of nuclear fissile and radioactive materials used by terrorists as a 'pure' or 'dirty' bomb. Its threat is significant, and therefore, the aim of the civilized world is to stop any possible illegal trafficking of such materials through Uzbekistan. To accomplish this task, the program aimed at equipping the customs check-points with the systems of pedestrian, vehicle and railroad portal radiation monitors was developed and initiated under international support. Realization of this program and its results are reported in this presentation. (author)

Energy and exergy analyses of energy consumptions in the industrial sector in South Africa

International Nuclear Information System (INIS)

Oladiran, M.T.; Meyer, J.P.

2007-01-01

The energy-utilization over a 10-year period (1994-2003) has been analysed for the South African industrial sector, which consumes more primary energy than any other sector of the economy. Four principal sub-sectors, namely iron and steel, chemical and petrochemical, mining and quarrying, and non-ferrous metals/non-metallic minerals were considered in this study. Primary-energy utilization data were used to calculate the weighted mean energy and exergy efficiencies for the sub-sectors and then overall values for the industrial sector were obtained. The results indicate that exergy efficiency is considerably lower than energy efficiency in all the sub-sectors, particularly in mining and quarrying processes, for which the values were approximately 83% and 16%, respectively. The performance of exergy utilization in the industrial sector can be improved by introducing various conservation strategies. Results from this study were compared with those for other countries

Full Text Available The paper is devoted to the analysis of Ukrainian fuel and energy sector (FES. The number of risks that threaten the stable supply of energy sources is growing. A high proportion of the energy intensity of developing economies in conjunction with their growing GDP leads to increased competition on world primary energy markets and causes significant fluctuations in energy prices, which negatively affect the global economy. There is also an important issue for world energy - limited use of non-renewable energy resources. Considering the prospects of development of Ukrainian FES, it is important to pay attention to patterns and trends of the global and national power. We have studied the basic trends of Ukrainian FES. It is the most important sector of the economy, and therefore its reform for market economy creation, price liberalization is a very important process. The current task of the energy sector of Ukraine is to be able to consistently produce and use energy to promote economic growth and improve quality of life.

A holistic perspective of various energy stakeholders regarding the Strengths, Weaknesses, Opportunities and Threats (SWOTs) of the energy sector in Macedonia is utilized as baseline to diagnose the current state and to sketch future action lines towards sustainable energy development. The resulting SWOT analyses pointed to the progressive adoption of European Union (EU) standards in energy policy and regulation as the most important achievement in the energy sector. The most important problems the national energy sector faces are scarce domestic resources and unfavorable energy mix, low electricity prices, a high degree of inefficiency in energy production and use, as well as insufficient institutional and human capacities. The formulated portfolio of actions towards enabling sustainable energy development urges the adoption of a comprehensive energy strategy built upon sustainability principles, intensified utilization of the natural gas, economic prices of electricity, structural changes in industry, promotion of energy efficiency and renewables, including Clean Development Mechanism (CDM) projects, enforcement of EU environmental standards and meeting the environmental requirements, as well as institutional and human capacity building.

This paper analyses progress and obstacles to gas sector reform in the most important CIS-Countries (Russia, Turkmenistan, Ukraine, Uzbekistan), taking a political economy perspective. This reform process is embedded in a very specific post-Soviet institutional framework stemming from the legacy of socialism. Firstly, we review the evolution of the gas sector for the period 1992-1998. The paper then identifies the post-Soviet specifies of gas sector restructuring, to which any reform strategy and technical assistance have to he adapted. We derive concrete, process-oriented policy conclusions to accelerate the reform process in a market-oriented way. The paper concludes with an evaluation of the perspectives of gas sector restructuring in this geopolitically strategic area of the world. (author)

Ward, Ian; Ogbonna, Anthony; Altan, Hasim

2008-01-01

The UK education and education-related services are said to be one of the fastest-growing export earners in recent years and are known to have had significant impacts at the micro- and macro-levels of the UK. This review looks at energy consumption of this fast growing sector. It concentrates on the energy consumption patterns of the funded higher education institutions in the UK. The findings indicate energy consumption in the sector has been on the increase in the 6 years up to 2006; rising by about 2.7% above the 2001 consumption levels. This increase is, however, not evenly spread across the entire sector. The high energy-consuming institutions appear to be increasing their net consumption, relative to other institutions. Gross internal area, staff and research student full-time equivalent were found to have highest correlation with energy consumption across the sector and may be used as proxy indicators for energy consumption as well as the targets of interventions

Dajic, N.; Mesarovic, M.

2008-01-01

Major Serbian energy policy goals set up by the new Energy Law (2004) emerge from the purpose to establish qualitatively new working and development conditions inside the energy production and consumption sectors under the new circumstances in the country and in the region of South Eastern Europe. This is expected to give a new impetus to the economic development of the Republic of Serbia by increasing energy efficiency, intensifying the use of renewable energy sources and reducing harmful emissions from energy production and consumption sectors, as well as to ease integration into regional and European energy markets. The above has also been de?ned by the 'Strategy of Serbian Energy Sector Development by the Year 2015' (adopted by the Serbian Parliament in 2005) and in more details by the 'Programme of the Implementation of the Strategy by the Year 2012' (adopted by the Serbian Government in 2007). Based on these strategic and other documents, which were drawn up with participation of the Serbian WEC MC as well, this paper presents a vision of the Serbian energy sector development during the period up to the year 2030.(author)

Lin, Boqiang; Wang, Ailun

2015-01-01

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

Energy and exergy utilization efficiencies in the Japanese residential/commercial sectors

Kondo, Kumiko

2009-01-01

Unlike the manufacturing sector, the residential/commercial sectors of Japan struggle to meet their environmental requirements. For instance, their CO 2 emission levels have increased tremendously since 1990. This research estimates energy and 'exergy (available energy)' efficiencies in Japan's residential/commercial sectors during the period 1990-2006. Since an exergy analysis reveals 'available energy losses', it is an effective tool to achieve sustainable societies. The primary objective of this paper is to examine the potential for advancing the 'true' energy efficiency in Japan's residential/commercial sectors-by observing energy and exergy efficiency disparities. The results show large differences between the overall energy and exergy efficiencies in the residential (60.12%, 6.33%)/commercial sectors (51.78%, 5.74%) in 2006. This implies great potential for energy savings in both sectors. Furthermore, this research suggests that the residential sector may face more difficulties than the commercial sector, although the latter appears to be less energy-efficient, according to recent statistics. This is because the disparity between energy and exergy efficiencies has expanded in the residential sector since 2000. This study illustrates the importance of exergy analyses in promoting sustainable energy policies and new adaptation strategies.

Gullev, L.

2000-01-01

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

Dincer, I.; Hussain, M.M.; Al-Zaharnah, I.

2004-01-01

In this paper we present an analysis of energy and exergy utilization in the transportation sector of Saudi Arabia by considering the sectoral energy and exergy flows for the years of 1990-2001. Energy and exergy analyses are conducted for its three subsectors, namely road, air and marine, and hence the energy and exergy efficiencies are obtained for comparison. Road subsector appears to be the most efficient one compared to air and marine subsectors. It is found that the energy efficiencies in air and marine subsectors are found to be equal to the corresponding exergy efficiencies due to the values of exergy grade function. A comparison of the overall energy and exergy efficiencies of Saudi Arabian transportation sector with the Turkish transportation sector is also presented for the year 1993 based on the data available. Although the sectoral coverage is not same for both countries, it is still useful to illustrate the situation on how subsectoral energy and exergy efficiencies vary over the years. Turkish transportation sector appears to be a bit more efficient for that particular year. It is believed that the present technique is practical and useful for analyzing sectoral energy and exergy utilization to determine how efficient energy and exergy are used in transportation sector. It is also be helpful to establish standards, based on exergy, to facilitate applications in industry and in other planning processes such as energy planning

Challenges and policies in Indonesia's energy sector

Dutu, Richard

2016-01-01

Fossil fuels are central to Indonesia's energy policy, and its main source of export revenues. However, insufficient investment, the lack of transport infrastructure and an unwieldy regulatory environment are inhibiting the sector from reaching its full potential. Looking ahead, growing environmental concerns combined with sharp falls in coal prices and the on-going shale gas revolution call into question the sustainability of an energy strategy based almost exclusively on fossil fuels. This viewpoint challenges Indonesia's current energy policy and proposes ways to increase its energy efficiency and use of renewables. In particular, its gas sector should be further developed to plug the gap until sufficient renewable energy, especially geothermal, comes on line. Government control over the oil industry via state-owned Pertamina should be gradually reduced. Clarifying, streamlining and publicising simple regulations in energy, especially regarding land rights and on-shore processing, and removing foreign-ownership restrictions will help bring much needed investment. The pressure on the environment of natural resource exploitation should also be addressed by properly defining property rights and regulations regarding forest land, and implementing a positive implicit carbon price. - Highlights: • Indonesia's energy sector faces many regulatory, environmental and infrastructure hurdles. • Indonesia's energy policy can be improved through greater use of renewables, especially geothermal. • The gas sector should be further developed until more renewable energy come on line. • Government control over the oil industry should be reduced to boost investment. • Clarifying and simplifying regulations is key to attracting foreign companies and protecting the environment.

In this paper, we deal with the analysis of energy and exergy utilization in the public and private sector of Saudi Arabia by considering the energy and exergy flows for the years between 1990 and 2001. Energy and exergy analyses for the public and private sector are undertaken to study the energy and exergy efficiencies. These sectoral efficiencies are then compared, and energy and exergy flow diagrams for the public and private sector over the years are presented, respectively. Energy and exergy efficiencies of the public and private sector are compared for its six sub-sectors, namely commercial, governmental, streets, Mosques, hospitals and charity associations, particularly illustrated for the year 2000. Hospital sub-sector appears to be the most energy efficient sector and government sub-sector the most exergy efficient one. The results presented here provide insights into the sectoral energy use that may assist energy policy makers for the country. It is believed that the present techniques are useful for analyzing sectoral energy and exergy utilization, and that they provide Saudi Arabia with energy savings through energy efficiency and/or energy conservation measures. It is also be helpful to establish standards to facilitate application in industry and in other planning processes such as energy planning.

Full Text Available Background. In spite of the works performed against iodine deficiency disorders (IDD, they still remain severe in Uzbekistan. The purpose of the study was to investigate the dynamics of the prevalence of IDD among the population in the Republic of Uzbekistan. Materials and methods. Epidemiological study of IDD in the Republic of Uzbekistan has been performed according to the World Health Organization (WHO recommendations. Degree of thyroid enlargement was determined according to the WHO classification. Such indexes, as assessment of urinary iodine concentration and evaluation of salt iodine concentration, have been analyzed. The data were compared with the results of previous years’ studies. Results. Estimation of the severity of IDD by the level of ioduria showed that the proportion of severe iodine deficiency (less than 20 μg/l decreased from 94.4 % in 1998 to 21.4 % in 2004, to 1.9 % in 2010 and to 1.9 % in 2016. The optimal level of iodine intake (more than 100 μg/l increased from 0 % in 1998 to 46.3 % in 2004, to 63.7 % in 2010 and 76.3 % in 2016. Comparative analysis of the prevalence of degree I and II diffuse goiter showed that in total the proportion of this disease was 72.8 % in 1998, 58.8 % in 2004, 40.2 % in 2010 and 28.3 % in 2016. Conclusions. The acceptance of law of Uzbekistan “On prevention of iodine deficiency diseases” in 2007 has substantially decreased the prevalence of IDD in Uzbekistan. Nevertheless, despite of large scale actions, our study of ioduria and salt iodine content in 2016 indicated that about 25 % of people in the country still prone to IDD.

Calculating economy-wide energy intensity decline rate: The role of sectoral output and energy shares

International Nuclear Information System (INIS)

Baksi, Soham; Green, Chris

2007-01-01

We specify formulas for computing the rate of decline in economy-wide energy intensity by aggregating its two determinants-technical efficiency improvements in the various sectors of the economy, and shifts in economic activity among these sectors. The formulas incorporate the interdependence between sectoral shares, and establish a one-to-one relation between sectoral output and energy shares. This helps to eliminate future energy intensity decline scenarios which involve implausible values of either sectoral share. An illustrative application of the formulas is provided, using within-sector efficiency improvement estimates suggested by Lightfoot-Green and Harvey

Since the introduction of market-oriented economy in 1986, Vietnam has made noticeable socio-economic progress. In this progress, the energy sector has played a vital role. This role is likely to deepen in the years to come as Vietnam strives to achieve even higher levels in economic progress. Such deepening in the role of energy, this paper argues, will heighten concerns about the security of energy supply, and economic, environmental, social and political consequences. In order to address these issues, Vietnam has over the last decade, developed a suite of energy policies. A deeper review of these policies suggests that they are typified by economic-growth orientation, exclusive focus on a single-sector or single issue, and largely neglect the significance of cross-sectoral and cross-thematic issues arising from the interdependencies between energy, economy, and the polity at large. The existing energy policy settings are, therefore, unlikely to be able to provide a satisfactory redress to the challenges noted above. This paper provides an overview of the current energy policies with a view to identify areas where further policy effort is needed in order to facilitate a sustainable development of the Vietnamese energy sector. - Highlights: > Identifying challenges faced by the Vietnamese energy sector. > Analyzing limitations of the existing energy policy settings (policies, strategies and institutions) in addressing these challenges. > Developing recommendations on improving the existing energy policy settings to provide a satisfactory redress for the challenges noted above.

Full Text Available Despite the ongoing programs aimed at the liquidation of iodine deficiency in the Republic of Uzbekistan, a high prevalence of iodine deficiency disorders (IDD is being observed. As a result of epidemiological studies in 1998 and 2004 it was found that the prevalence of endemic goiter among children in the country was 64.5 and 51.6%, respectively. Dynamics of iodine deficiency decrease was associated with active work on liquidation of IDD: provision of salt-mining and salt-processing plants with iodizing equipment and potassium iodate, conducting of large-scale community health measures among different social gropus, on public enterprises and in private sector, carrying out of regular monitoring of iodine content in salt and urine. In May 2007 there was passed the law of Republic of Uzbekistan «About prevention of iodine deficiency disorders». In this work there was carried out the analysis of IDD in Khoresm region according to WHO recommendations, by sentinel method. It was revealed that prevalence of endemic goiter has been reduced to 38.7 % in 2012 (positive dymanics. We obtained data on the normal content of iodine in salt and urine — 75 and 60.6 %, respectively. Thus, it is found that the prevalence of IDD in the Khorezm region in the dynamics is reduced, although iodine deficiency remains severe.

Although energy consumption in the industry sector has almost been stable, energy consumption in the transportation (passenger and freight) sector has increased much after the oil crisis. The increase of energy consumption in the passenger sector can be attributed to the increase in transportation by private passenger vehicles; while the increase in the freight sector was due to the modal shift to trucks. Among transportation methods, automobiles, i.e. passenger vehicles and trucks, are now dominant in terms of energy consumption and also in terms of amount of transportation. Therefore implementing energy conservation measures relating to automobiles is very important in order to suppress the energy consumption in the transportation sector. This report summarizes the results of investigation on energy conservation measures, especially relevant to automobiles. It was found from the investigation that most promising and effective technologies or measures are promoting market penetration of vehicles satisfying ''top runner standard'', development and employment of hybrid vehicles, and introduction of vehicles with ''idling-stop'' systems.

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

Sustainable Energy for All and the private sector

Bellanca, Raffaella; Wilson, Emma

2012-06-15

The UN's Sustainable Energy for All initiative (SE4ALL) has a strong focus on the private sector to deliver universal energy access, improved efficiency and increased investment in renewable energy. Leading private sector associations have bought into SE4ALL, including the World Business Council for Sustainable Development (WBCSD) and the Global Compact. However, critics argue that SE4ALL is focusing too much on large-scale infrastructure investment and is missing opportunities to stimulate enterprise more locally and to benefit the poorest. The private sector – including large and smaller-scale businesses, both local and international – is keen to get involved in energy access in low-income markets and sees the value of an initiative such as SE4ALL. Yet some feel that SE4ALL is failing to engage all levels of the private sector effectively. To deliver universal energy access, SE4ALL needs to address the lack of finance for enterprises and end users, especially in untested markets; infrastructure and support services for new businesses; local skills, capacity and information about workable models; and favourable policy frameworks. With the right incentives, business can open up low-income markets by providing lifeimproving services to emerging middle class populations who are still excluded from energy access. To reach the poorest SE4ALL can promote private sector partnerships with government and NGOs, encourage corporate responsibility initiatives and support social entrepreneurs.

The article shows how the financing structure of the companies from the fuel and energy sector, listed on the Warsaw Stock Exchange, has evolved over the years. The authors also estimated the cost of equity. The results were compared with the chosen mining companies in Poland. Companies from the energy sector have lower investment risk than companies from the fuel sector. Looking at the profitability of investments it should be emphasized that the financing by outside capital is more advantageous than equity financing.

Energy savings in CSFR - building sector

International Nuclear Information System (INIS)

Jacobsen, F.R.

1993-01-01

The Czechoslovak/Danish project on energy savings in buildings proves that it is possible to save up to 30% of the energy in buildings. 10% can be saved at an investment of 27 bill KCS. The total investment that is needed to save 30% is 140 bill KCS. Further energy savings can be obtained through more energy efficient supply systems. Information dissemination is important for the energy saving programme as are economic incentives. Investments in energy savings should be profitable for the investor, but this is not the case in the Czech and Slovak republics today. Changes are needed. Energy prices are still to low, compared to investment costs. Financial possibilities are not satisfactory for private investors. Price systems are not favourable to investment in energy savings. Training is needed for boiler men and energy consultants. Legislation is essential for the support of the full range of activities in the energy sector. Research and Development activities must back up the development of the sector. Pilot projects can illuminate the savings potential. The production of technical equipment for control and metering and production of insulation materials must be promoted. (AB)

Measuring energy performance with sectoral heterogeneity: A non-parametric frontier approach

International Nuclear Information System (INIS)

Wang, H.; Ang, B.W.; Wang, Q.W.; Zhou, P.

2017-01-01

Evaluating economy-wide energy performance is an integral part of assessing the effectiveness of a country's energy efficiency policy. Non-parametric frontier approach has been widely used by researchers for such a purpose. This paper proposes an extended non-parametric frontier approach to studying economy-wide energy efficiency and productivity performances by accounting for sectoral heterogeneity. Relevant techniques in index number theory are incorporated to quantify the driving forces behind changes in the economy-wide energy productivity index. The proposed approach facilitates flexible modelling of different sectors' production processes, and helps to examine sectors' impact on the aggregate energy performance. A case study of China's economy-wide energy efficiency and productivity performances in its 11th five-year plan period (2006–2010) is presented. It is found that sectoral heterogeneities in terms of energy performance are significant in China. Meanwhile, China's economy-wide energy productivity increased slightly during the study period, mainly driven by the technical efficiency improvement. A number of other findings have also been reported. - Highlights: • We model economy-wide energy performance by considering sectoral heterogeneity. • The proposed approach can identify sectors' impact on the aggregate energy performance. • Obvious sectoral heterogeneities are identified in evaluating China's energy performance.

In this paper, sectoral energy and exergy analysis model is applied to the utility and commercial sectors of Malaysia by considering the energy and exergy flows from 1990 to 2003. The energy and exergy efficiencies are determined for the sub-sectors and devices used in these two sectors. It has been found the hydroelectric power plant sub-sector is more energy and exergy efficient compared to the thermal power plant sub-sector. The energy and exergy efficiencies of utility and commercial sectors of Malaysia are compared with a few other countries around the world as well. The utility and commercial sectors of Malaysia are found to be more efficient than that of Thailand, Brunei, China, and Vietnam in 1999

Energy conservation in China: Key provincial sectors at two-digit level

2013-01-01

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

1996-12-31

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

An analysis of the Dutch service sector. Energy consumption and trends

International Nuclear Information System (INIS)

Ramirez, A.; Patel, M.; Blok, K.

2002-09-01

Energy efficiency and its implications for a decrease in carbon dioxide emissions have been a main force behind the current debate on energy issues. Until now, the attention of policy-makers and scientists has been mainly focused on the industrial and residential sectors, although the transport sector has gained relevance in the fast few years. The service sector, on the other hand, has remained at the bottom of the priority list. The main goal of this paper is to explore patterns of energy consumption and energy intensity in the Dutch service sector in the last 15 years. This paper is divided into two parts. The first part deals with developments for the whole sector, including a decomposition analysis, and the second part analyses sectoral developments for five sub-sectors: Wholesale and retail trade, hotels and restaurants; Financial institutes; Real estate renting and business activities; Education and Hospitals. At the aggregate level we have found a strong increase in energy consumption, especially in electricity. Furthermore, we found no evidence of significant decrease in energy intensity in the last decade. Furthermore, the decomposition analysis showed that (a) the activity effect (value added) has been the main driving force behind the increase of energy consumption of the service sector, (b) an increase in labour intensity has also boosted energy consumption and (c) energy intensity (in terms of energy per employee) did not have a significant role on decreasing energy use. At the subsectoral level the picture is blurred, especially due to the lack of good quality data. With exception of the sector Real estate renting and business activities which showed a decrease in energy intensity of about 20% between 1993 and 1999, the decrease in energy intensity is quite low. Hence, the results point towards a failure of actual energy policies to address the service sector. This is in contrast to the fact that, due to the high share of electricity consumption and

Marine renewable energy sector early-stage supply chain

International Nuclear Information System (INIS)

2011-01-01

Marine renewable energy is an emergent sector in Canada. Although supply chain studies have been performed on the United Kingdom and the United States markets, no study has been conducted yet in Canada. The aim of this study was therefore to perform a supply chain analysis in Canada to assess the maturity, strengths, and weaknesses of the sector and determine where the opportunities lie. The study emphasises that the sector is still at the prototype stage in Canada and that the industry must learn to improve its technology and begin to take on large scale projects. Canada has several strengths in the marine renewable energy sector, mainly in terms of resources and facilities, but there are also weaknesses pertaining to technology development and experience. The study concluded that the development of the sector must be centered on a solid vision; in the near term, technological innovation is needed to reach pre-commercialization while in the long term, the sector should aim for commercial application.

Energy sector reform, energy transitions and the poor in Africa

2008-01-01

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

Utlu, Zafer; Hepbasli, Arif

2007-01-01

The present study deals with evaluating the utility sector in terms of energetic and exergetic aspects. In this regard, energy and exergy utilization efficiencies in the Turkish utility sector over a wide range of period from 1990 to 2004 are assessed in this study. Energy and exergy analyses are performed for eight power plant modes, while they are based on the actual data over the period studied. Sectoral energy and exergy analyses are conducted to study the variations of energy and exergy efficiencies for each power plants throughout the years, and overall energy and exergy efficiencies are compared for these power plants. The energy utilization efficiencies for the overall Turkish utility sector range from 32.64% to 45.69%, while the exergy utilization efficiencies vary from 32.20% to 46.81% in the analyzed years. Exergetic improvement potential for this sector are also determined to be 332 PJ in 2004. It may be concluded that the methodology used in this study is practical and useful for analyzing sectoral and subsectoral energy and exergy utilization to determine how efficient energy and exergy are used in the sector studied. It is also expected that the results of this study will be helpful in developing highly applicable and productive planning for energy policies

Regional energy rebound effect: The impact of economy-wide and sector level energy efficiency improvement in Georgia, USA

Yu, Xuewei; Moreno-Cruz, Juan; Crittenden, John C.

2015-01-01

Rebound effect is defined as the lost part of ceteris paribus energy savings from improvements on energy efficiency. In this paper, we investigate economy-wide energy rebound effects by developing a computable general equilibrium (CGE) model for Georgia, USA. The model adopts a highly disaggregated sector profile and highlights the substitution possibilities between different energy sources in the production structure. These two features allow us to better characterize the change in energy use in face of an efficiency shock, and to explore in detail how a sector-level shock propagates throughout the economic structure to generate aggregate impacts. We find that with economy-wide energy efficiency improvement on the production side, economy-wide rebound is moderate. Energy price levels fall very slightly, yet sectors respond to these changing prices quite differently in terms of local production and demand. Energy efficiency improvements in particular sectors (epicenters) induce quite different economy-wide impacts. In general, we expect large rebound if the epicenter sector is an energy production sector, a direct upstream/downstream sector of energy production sectors, a transportation sector or a sector with high production elasticity. Our analysis offers valuable insights for policy makers aiming to achieve energy conservation through increasing energy efficiency. - Highlights: • We developed a CGE model to investigate economy-wide energy rebound in Georgia, USA. • The CGE model has detailed treatment for different energy inputs for production. • The model has a highly disaggregated sector profile helpful for policy making. • We compared the economy-wide impact shocks in different epicenter sectors. • We analyzed why epicenters generate dramatically different economy-wide impacts.

Understanding industrial energy use: Physical energy intensity changes in Indian manufacturing sector

Sudhakara Reddy, B.; Kumar Ray, Binay

2011-01-01

This study develops and examines physical energy intensity indicators in five industrial sub-sectors-iron and steel, aluminum, textiles, paper, and cement-and investigates mitigation options for energy related CO 2 emissions (during 1991-2005). Decomposition analysis has been employed to separate the structural effect (share of different products in the sector) from pure intensity effect (efficiency increase through technical improvement) for each industry. The results show that the combined effect (considering both structural and intensity effects together) on both iron and steel and paper and pulp industries is negative while it is positive for aluminum and textiles. The intensity effect for all the industries, barring textiles, is negative showing improvement in energy efficiency; iron and steel in particular, has seen a decrease of 134 PJ in energy consumption owing to improvements in efficiency. However, energy intensity in textiles has risen by 47 PJ due to increased mechanization. Structural effect is positive in aluminum and iron and steel industries indicating a movement towards higher energy-intensive products. In the case of aluminum, positive structural effect dominates over negative intensive effect whereas negative intensive effect dominates iron and steel industry. The paper helps in designing policies for improving productivity and reduce energy consumption in India's manufacturing sector. - Highlights: → The study develops physical energy intensity indicators in industrial sub-sectors of India. → It identifies technological and other options for reduction in energy consumption. → The study quantifies savings in energy as well as CO 2 emissions. → The indicators are useful in examining structural changes.

Uzbekistan is located on the cross-roads from the north-Russia, Western Europe-to the south-Afghanistan, Iran, Iraq and others. The appearance of terrorist organizations urged some Asian countries to make the nuclear weapons, the making the task of stopping the transportation of nuclear materials and technologies from the north (from countries possessing nuclear weapon) to the south (to countries desiring to have weapons and its components) a reality. To resolve this problem, on the main transportation routes, 'Yantar' stationary radiation monitors of Russian production were installed, and development and production of monitors of our own make was started. This paper covers these works as well as those on preventing possible terrorist attacks on nuclear objects of Uzbekistan

Full Text Available The beginning of the XXI century was marked by a number of serious problems, including cancer, world hunger, environmental problems and increasing every year the problem of global terrorism, which poses a great threat to the security of the modern multipolar world. Uzbekistan today occupies a firm position in fight against terrorist threat. The principled position of Uzbekistan in the fight against terrorism is that “no country should exclude their participation in the fight against global terrorism, there must be no transit zones and "green corridors" for terrorist organizations”. The Central Asian region is one of the most vulnerable, because it is necessary to pay special attention to the strategy of the anti-terrorist security of the countries included in the structure of the Central Asian region. In this article, we consider the anti-terrorist policy of Uzbekistan in the framework of the regional anti-terrorist policy of the SCO.

Chedid, R.B.; Ghajar, R.F.

2004-01-01

This paper examines the merits of implementing energy efficiency policies in the building sector in Lebanon following the approach normally adopted in Climate Change studies. The paper first examines the impact of the energy sector on the Lebanese economy, and then assesses the feasibility of implementing suitable energy efficiency options in the building sector. For this purpose, a detailed analysis of the building sector in Lebanon is presented with emphasis on the thermal characteristics of building envelopes and the energy consuming equipment. The long-term benefits of applying energy efficiency options in the building sector are then assessed using a scenario-type analysis that compares these benefits against those of a baseline scenario that assumes no significant implementation of energy efficiency policies. Finally, feasible options are highlighted and recommendations to remove the major barriers hindering the penetration of energy efficiency options in the Lebanese market are provided

Energy sector in conditions of market economy

The main dilemma of energy sector in market conditions is: regulation of the monopole producer and/or competition. There is no simple answer and the arguments for and against should be based on the macro economical determination of what kind of market is available for particular energy goods (perfect, monopolistic, oligopolistic, competition of monopolists) and what is the final purpose (improvement in efficiency, service, energy independence, regional development, etc.). Two polar models of economic management in energy sector are distinguished: 1) Free access to transfer net or competition between producers. 2) State regulation of the local monopolist. The experience of Great Britain and US are described as examples of both models. A special attention is paid to pricing methods at regulated monopole. 7 refs. (author)

A new NAMA framework for dispersed energy end-use sectors

International Nuclear Information System (INIS)

Cheng, C.-C.

2010-01-01

This paper presents a new approach for a nationally appropriate mitigation actions (NAMA) framework that can unlock the huge potential for greenhouse gas mitigation in dispersed energy end-use sectors in developing countries; specifically, the building sector and the industrial sector. These two sectors make up the largest portions of energy consumption in developing countries. However, due to multiple barriers and lack of effective polices, energy efficiency in dispersed energy end-use sectors has not been effectively put into practice. The new NAMA framework described in this paper is designed to fulfill the demand for public policies and public sector investment in developing countries and thereby boost private sector investment through project based market mechanisms, such as CDM. The new NAMA framework is designed as a need-based mechanism which effectively considers the conditions of each developing country. The building sector is used as an example to demonstrate how NAMA measures can be registered and implemented. The described new NAMA framework has the ability to interface efficiently with Kyoto Protocol mechanisms and to facilitate a systematic uptake for GHG emission reduction investment projects. This is an essential step to achieve the global climate change mitigation target and support sustainable development in developing countries.

Foreign Direct Investments in Central Asian Energy: A CGE Model

Directory of Open Access Journals (Sweden)

Michael P. BARRY

2009-05-01

Full Text Available Turkmenistan, Uzbekistan, and Kazakhstan have adopted significant legislative changes since the fall of the former Soviet Union in an effort to attract foreign direct investment into their energy sectors. Of the three republics, Kazakhstan has been the most successful in attracting foreign interest, but all three republics face significant challenges in further development of oil and gas infrastructure. Even if these countries are completely successful in bringing in foreign investment, a question will remain: who wins and who loses in these countries. Using updated data, this paper will use a computable general equilibrium model to measure the effects of FDI into Central Asia. Results of the model suggest that the region would be better off overall from foreign investment in its natural gas sector, due mostly to improvements in overall production efficiency and its overall terms of trade. However, the gain in the natural gas sector would come at the expense of production and net exports of non-petroleum related industries.

Through centuries of revolution, war and strife, the people of Uzbekistan have built a reputation as skilled and tenacious merchants. Since antiquity, when the Silk Road from China turned toward Europe at Smarakand, they have been master traders of such valuable commodities as cotton, fruits, vegetables, spices and gold. Now, they're about to introduce another of their specialties to the world: Uranium. Uranium mining in the country is controlled by a new, independent company, the Kizilkumredmetzoloto, parent of the Navoi Mining ampersand Metallurgy Combine [NMMC]. Established in 1958 at the height of the Cold War, when uranium mining for military stockpiles got started in earnest, Navoi was wholly owned by the USSR's Ministry of Medium Machine Building. Up until 1991, virtually all of Navoi's uranium production, strictly in the form of uranium concentrates, was used for either military purposes or for nuclear power plants within the former Soviet Union. The republic exerted no control over the final destination of its uranium. All production and operating decisions for Navoi's mines were dictated by the Soviet Union's Ministry of Atomic Power ampersand Industry [MAPI], which developed annual quotas for uranium production in each republic of the country. Uranium from the republics was sold to Techsnabexport [Tenex], the distribution and marketing arm of MAPI. Exports to other countries were handled strictly by Tenex

Transportation sector is the second most energy consuming sector after industrial sector, accounting for 40% of total energy consumption in Malaysia. The transportation sector is one of the most energy intensive sectors in the country and relies primarily on petroleum products, which in total account for nearly 98% of the total consumption in the sector. Since it is heavily reliant on petroleum based fuels, the sector contributes significantly to the greenhouse gas (GHG) emissions. The need to reduce the greenhouse gas emission is paramount as Malaysia at Conference of the Parties (COP15) pledged to reduce its carbon intensity by 40% by 2020 from 2005 level subject to availability of technology and finance. Transport sector will be among the first sectors that need to be addressed to achieve this goal, as two-thirds of the emissions come from fuel combustion in transport sector. This paper will analyse the factors influencing the transport sector's growth and energy consumption trends and discuss the key issues and challenges for greener environment and sustainable transportation in Malaysia. The paper will also discuss the policy and strategic options aimed towards energy efficient pathways in Malaysia.

Irsag, Bojan; Pukšec, Tomislav; Duić, Neven

2012-01-01

Today, tourism represents one of the backbones of Croatian economy and one of the main factors of its growth. Combined with catering trade sector, tourism represents a significant energy consumer that has the tendencies of future growth. Since services sector, which tourism–catering trade sector is a part of, is not yet well described regarding future energy balances it would be very interesting to see how could possible future growth in tourism influence energy consumption of the services sector in Croatia. Through this paper long term energy demand projections of tourism–catering trade sector were studied with special emphasis on future growth of tourism in Croatia as well as different mechanisms that might lead to certain energy savings. Bottom-up approach was chosen as the most suitable one since it allows better quantification of different measures, technological or legal, that would influence future energy demand. Downside of this approach is extensive input data that is required to analyse and model future energy demand which is roughly divided into heating/cooling section and all other consumption. Results show that additional energy savings in the tourism–catering trade sector are possible if careful and rational demand side planning is in place. -- Highlights: ► Future energy demand of Croatian touristm–catering trade sector has been modelled. ► Model is roughly divided into two basic modes (heating/cooling and all other consumption). ► Different factors influencing future energy demand were implemented into the model. ► Possibilities for energy efficiency improvements have been presented.

Converting Energy Subsidies to Investments: Scaling-Up Deep Energy Retrofit in Residential Sector of Ukraine

Science.gov (United States)

Denysenko, Artur

After collapse of the Soviet Union, Ukraine inherited vast and inefficient infrastructure. Combination of historical lack of transparency, decades without reforms, chronical underinvestment and harmful cross-subsidization resulted in accumulation of energy problems, which possess significant threat to economic prosperity and national security. High energy intensity leads to excessive use of energy and heavy reliance on energy import to meet domestic demand. Energy import, in turn, results in high account balance deficit and heavy burden on the state finances. A residential sector, which accounts for one third of energy consumption and is the highest consumer of natural gas, is particularly challenging to reform. This thesis explores energy consumption of the residential sector of Ukraine. Using energy decomposition method, recent changes in energy use is analyzed. Energy intensity of space heating in the residential sector of Ukraine is compared with selected EU member states with similar climates. Energy efficiency potential is evaluated for whole residential sector in general and for multistory apartment buildings connected to the district heating in particular. Specifically, investments in thermal modernization of multistory residential buildings will result in almost 45TWh, or 3.81 Mtoe, of annual savings. Required investments for deep energy retrofit of multistory buildings is estimated as much as $19 billion in 2015 prices. Experience of energy subsidy reforms as well as lessons from energy retrofit policy from selected countries is analyzed. Policy recommendations to turn energy subsidies into investments in deep energy retrofit of residential sector of Ukraine are suggested. Regional dimension of existing energy subsidies and capital subsidies required for energy retrofit is presented.

This study computes the pure technical efficiency (PTE) and energy-saving target of Taiwan's service sectors during 2001–2008 by using the input-oriented data envelopment analysis (DEA) approach with the assumption of a variable returns-to-scale (VRS) situation. This paper further investigates the effects of industry characteristics on the energy-saving target by applying the four-stage DEA proposed by Fried et al. (1999). We also calculate the pre-adjusted and environment-adjusted total-factor energy efficiency (TFEE) scores in these service sectors. There are three inputs (labor, capital stock, and energy consumption) and a single output (real GDP) in the DEA model. The most energy efficient service sector is finance, insurance and real estate, which has an average TFEE of 0.994 and an environment-adjusted TFEE (EATFEE) of 0.807. The study utilizes the panel-data, random-effects Tobit regression model with the energy-saving target (EST) as the dependent variable. Those service industries with a larger GDP output have greater excess use of energy. The capital–labor ratio has a significantly positive effect while the time trend variable has a significantly negative impact on the EST, suggesting that future new capital investment should also be accompanied with energy-saving technology in the service sectors. - Highlights: • The technical efficiency and energy-saving target of service sectors are assessed. • The pre-adjusted and environment-adjusted total-factor energy efficiency scores in services are assessed. • The industrial characteristic differences are examined by the panel-data, random-effects Tobit regression model. • Labor, capital, and energy and an output (GDP) are included in the DEA model. • Future new capital investment should also be accompanied with energy-saving technology in the service sectors

Transport energy use in Sweden increased by 80% during the period 1970 to 2008. Today, the transport sector is responsible for a quarter of Sweden's energy use. Since the transport sector is almost exclusively using fossil fuels its conversion to other fuels/energy sources will have a major impact in the coming years, with the increasing requirements to reduce emissions of greenhouse gases. The first chapter reports the official energy statistics for the transport sector. The second chapter presents a breakdown of energy use for freight and passengers for each transport modes. However, it is important to emphasize that the division of personal and freight does not belong to the official energy statistics

Reliable, safe, and secure electricity is essential for economic and social development and a necessary input for many sectors of the economy. However, electricity generation and associated processes make up a significant portion of global greenhouse gas (GHG) emissions contributing to climate change. Furthermore, electricity systems are vulnerable to climate change impacts - both short-term events and changes over the longer term. This vulnerability presents both near-term and chronic challenges in providing reliable, affordable, equitable, and sustainable energy services. Within this context, developing countries face a number of challenges in the energy sector, including the need to reliably meet growing electricity demand, lessen dependence on imported fuels, expand energy access, and improve stressed infrastructure for fuel supply and electricity transmission. Energy efficiency (EE) and renewable energy (RE) technical solutions described in this paper can bridge action across climate change mitigation and resilience through reducing GHG emissions and supporting electric power sector adaptation to increasing climate risk. Integrated planning approaches, also highlighted in this paper, play an integral role in bringing together mitigation and resilience action under broader frameworks. Through supporting EE and RE deployment and integrated planning approaches, unique to specific national and local circumstances, countries can design and implement policies, strategies, and sectoral plans that unite development priorities, climate change mitigation, and resilience.

Linking energy efficiency legislation and the agricultural sector in South Africa

2017-04-01

Full Text Available There are different ways of measuring energy efficiency. Although there is no generally agreed definition of the concept, it should, however, always be approached according to particular circumstances and contexts. As such, technological, operational, performance and equipment efficiencies should be taken into consideration. Generally, energy utilisation in most sectors of the South African economy is inefficient. This requires more energy needs to be generated in order to cater for losses. An increase in generation causes environmental problems at global, regional and local levels. A review of literature on energy efficiency was undertaken and a gap identified between legislation and efficiency in the agricultural sector. This article seeks to suggest ways of implementing an energy legislation in this sector in South Africa. Such implementation will address concerns in terms of harnessing, generating and utilising energy in different sectors in South Africa. Legislation is vital in reducing energy consumption in the agricultural sector. It also ensures efficient use of energy and the maintenance of current levels of production.

Energy efficiency in the industrial sector. Model based analysis of the efficient use of energy in the EU-27 with focus on the industrial sector

Energy efficiency is a highly important topic and currently omnipresent in the energy political discussion. Despite this high importance there's no common understanding even concerning the definition of the term energy efficiency. In addition, there are plenty so called energy efficiency targets and several indicators. Therefore this study should provide a deepened understanding of the efficient use of energy. The inconsistent definition of energy efficiency is related to the use of this term for a specific as well as an absolute reduction of energy consumption. Furthermore both static views on efficiency as a status and also dynamic views on efficiency as an improvement of a value compared to a reference number are used. Additional differences occur in the evaluation of the energy use and in the selection of a reference value in a key figure to assess energy efficiency. Moreover the focus of the current general understanding is mainly only on the consumption of energy. All other resources next to the energy input which are needed to provide energy services are not considered even though there are strong interactions and substitution possibilities among these resources. Hence the understanding of energy efficiency is extended in this study by these additional resources which were not considered yet. Based on this extension the efficient use of the resource energy is a result of an optimisation of the relation of these total costs of all resources to the related benefit. To determine the efficient use of energy in the industrial sector, a deeper understanding of the sector and its characteristics is necessary. The industrial sector is the largest consumer of electricity within the EU. Also a quarter of the final energy consumption and about 20 % of the CO 2 emissions are related to this sector. Typical for this sector are the heterogeneous and high temperature level of the heat demand and the process emissions which accrue in transformation processes. The subsectors

Integrated assessment models have been used to project both baseline and mitigation greenhouse gas emissions scenarios. Results of these scenarios are typically presented for a number of world regions and end-use sectors, such as industry, transport, and buildings. Analysts interested in particular technologies and policies, however, require more detailed information to understand specific mitigation options in relation to business-as-usual trends. This paper presents sectoral trend for two of the scenarios produced by the Intergovernmental Panel on Climate Change's Special Report on Emissions Scenarios. Global and regional historical trends in energy use and carbon dioxide emissions over the past 30 years are examined and contrasted with projections over the next 30 years. Macro-activity indicators are analyzed as well as trends in sectoral energy and carbon demand. This paper also describes a methodology to calculate primary energy and carbon dioxide emissions at the sector level, accounting for the full energy and emissions due to sectoral activities.

Measuring Energy Efficiency in China’s Transport Sector

Directory of Open Access Journals (Sweden)

Han Hao

2017-05-01

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

Energy-economy interactions revisited within a comprehensive sectoral model

Hanson, D. A.; Laitner, J. A.

2000-07-24

This paper describes a computable general equilibrium (CGE) model with considerable sector and technology detail, the ``All Modular Industry Growth Assessment'' Model (AMIGA). It is argued that a detailed model is important to capture and understand the several rolls that energy plays within the economy. Fundamental consumer and industrial demands are for the services from energy; hence, energy demand is a derived demand based on the need for heating, cooling mechanical, electrical, and transportation services. Technologies that provide energy-services more efficiently (on a life cycle basis), when adopted, result in increased future output of the economy and higher paths of household consumption. The AMIGA model can examine the effects on energy use and economic output of increases in energy prices (e.g., a carbon charge) and other incentive-based policies or energy-efficiency programs. Energy sectors and sub-sector activities included in the model involve energy extraction conversion and transportation. There are business opportunities to produce energy-efficient goods (i.e., appliances, control systems, buildings, automobiles, clean electricity). These activities are represented in the model by characterizing their likely production processes (e.g., lighter weight motor vehicles). Also, multiple industrial processes can produce the same output but with different technologies and inputs. Secondary recovery, i.e., recycling processes, are examples of these multiple processes. Combined heat and power (CHP) is also represented for energy-intensive industries. Other modules represent residential and commercial building technologies to supply energy services. All sectors of the economy command real resources (capital services and labor).

Impacts of energy subsidy reform on the Malaysian economy and transportation sector

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

Full text: Soil is one of the main components of biosphere, which is subject to Man's economic activity from year to year. Unfortunately, during last 50-60years it became an object of the chemization (the treatment of crop by poison chemicals and the usage of mineral fertilizers).Thus, definite pre-conditions are created to migrate to substances applied along the soil horizon. These substances fall into organism of Man and animals through soil-contacting media: plants, air, water. In this respect the instrumental neutron-activation techniques which allows determination of about 40 chemical elements in soils and other objects of environment, with detection limit equal to 0.001-10.0mg/kg and not more than 30% uncertainty, are provided with the Ge -detector (the Canberra firm). The report discusses some metrological points of INAA concerning the objects of environment, in particular, the influence of space-time non-uniformity of chemical element distributions on the reliability of analysis results. The elaborated techniques make it possible to: - establish the elemental composition of soils, cotton, natural waters, mineral fertilizers, aerosol dust of near land layer of various climatic zones of Uzbekistan, including the airs around the Aral sea. - study of the interrelation between the soil elemental composition and the chemism in the evolution of pathological processes - find the correlation between the cotton returns and Mn contents in soils and to elaborate on this base a new way to value the presown grain quality - choose the wall material of ancient monuments of a region, which were not strongly subjected to ecological impact, as standards to monitor the background of chemical elements in soils - value the ecologically agrochemical conditions of soils for main cotton-sawing zones of Uzbekistan - perform a large scale mapping of soils to find the Mn contents and to elaborate the technology of introduction of Mn - containing microfertilizers - estimate the

Full text: Soil is one of the main components of biosphere, which is subject to Man's economic activity from year to year. Unfortunately, during last 50-60years it became an object of the chemization (the treatment of crop by poison chemicals and the usage of mineral fertilizers).Thus, definite pre-conditions are created to migrate to substances applied along the soil horizon. These substances fall into organism of Man and animals through soil-contacting media: plants, air, water. In this respect the instrumental neutron-activation techniques which allows determination of about 40 chemical elements in soils and other objects of environment, with detection limit equal to 0.001-10.0mg/kg and not more than 30% uncertainty, are provided with the Ge -detector (the Canberra firm). The report discusses some metrological points of INAA concerning the objects of environment, in particular, the influence of space-time non-uniformity of chemical element distributions on the reliability of analysis results. The elaborated techniques make it possible to: - establish the elemental composition of soils, cotton, natural waters, mineral fertilizers, aerosol dust of near land layer of various climatic zones of Uzbekistan, including the airs around the Aral sea. - study of the interrelation between the soil elemental composition and the chemism in the evolution of pathological processes - find the correlation between the cotton returns and Mn contents in soils and to elaborate on this base a new way to value the presown grain quality - choose the wall material of ancient monuments of a region, which were not strongly subjected to ecological impact, as standards to monitor the background of chemical elements in soils - value the ecologically agrochemical conditions of soils for main cotton-sawing zones of Uzbekistan - perform a large scale mapping of soils to find the Mn contents and to elaborate the technology of introduction of Mn - containing microfertilizers - estimate the

Dramatic changes have taken place in China's energy sector over the past decade. These changes have important implications for energy consumption, trade, production and regulatory policies in China and beyond. The objective of this paper is to review some of the key issues associated with deregulation and growth in China's energy sector. Specifically, the paper presents a survey of recent reforms in this sector; it also analyses the impact of deregulation on energy policy, ownership, foreign investment and trade, and sheds some lights on the sources of growth in China's energy sector

(How) does sectoral detail affect the robustness of policy insights from energy system models? The refining sector's example

International Nuclear Information System (INIS)

Nicolas, Claire; Saint-Antonin, Valerie; Tchung-Ming, Stephane

2014-01-01

In this research, we rekindle an old debate by questioning the impact on mitigating policy evaluation of detailing a sub-sector in a global energy-transportation model. We chose the refining sector because it is a relevant case of a sector for which representation widely differs across models and because it offers a unique set of complex joint production in the energy sector. To investigate whether the level of detail in the description of the refinery impacts optimal mitigation options, we take the example of a long-term, national, linear programming based, energy-transport system model (TIMES based). We found that the refinery description used in the energy system model matters when trying to evaluate energy or climate policy applied to the transportation sector. It impacts the policy costs but also the technology trajectories chosen at the optimum. Essentially, the balance between energy efficiency and carbon intensity of transport may be affected by the accuracy of the description of the pivotal refining sector. Consequently, increasing this sector accuracy level should not only be motivated by the wish to gain wider quantitative insights on potential evolution of the energy system but also by the wish to improve the robustness of the model outcomes.

High Energy Colliders and Hidden Sectors

Science.gov (United States)

Dror, Asaf Jeff

This thesis explores two dominant frontiers of theoretical physics, high energy colliders and hidden sectors. The Large Hadron Collider (LHC) is just starting to reach its maximum operational capabilities. However, already with the current data, large classes of models are being put under significant pressure. It is crucial to understand whether the (thus far) null results are a consequence of a lack of solution to the hierarchy problem around the weak scale or requires expanding the search strategy employed at the LHC. It is the duty of the current generation of physicists to design new searches to ensure that no stone is left unturned. To this end, we study the sensitivity of the LHC to the couplings in the Standard Model top sector. We find it can significantly improve the measurements on ZtRtR coupling by a novel search strategy, making use of an implied unitarity violation in such models. Analogously, we show that other couplings in the top sector can also be measured with the same technique. Furthermore, we critically analyze a set of anomalies in the LHC data and how they may appear from consistent UV completions. We also propose a technique to measure lifetimes of new colored particles with non-trivial spin. While the high energy frontier will continue to take data, it is likely the only collider of its kind for the next couple decades. On the other hand, low-energy experiments have a promising future with many new proposed experiments to probe the existence of particles well below the weak scale but with small couplings to the Standard Model. In this work we survey the different possibilities, focusingon the constraints as well as possible new hidden sector dynamics. In particular, we show that vector portals which couple to an anomalous current, e.g., baryon number, are significantly constrained from flavor changing meson decays and rare Z decays. Furthermore, we present a new mechanism for dark matter freezeout which depletes the dark sector through an

Household energy and climate mitigation policies: Investigating energy practices in the housing sector

International Nuclear Information System (INIS)

Schaffrin, André; Reibling, Nadine

2015-01-01

One central aim of climate change mitigation in the European Union is to reduce energy consumption in the housing sector. In order to ensure effectiveness of policies targeting household energy conservation, it is important to investigate existing energy practices of different social groups. This article describes and explains energy practices in three leading states in environmental politics, technological innovation, and support for renewable energy production: Denmark, Austria, and the United Kingdom. Based on a longitudinal analysis of housing utility costs from the European Community Statistics on Income and Living Conditions we show that income plays a central role in households' energy practices. While high-income households have higher overall energy consumption, low-income groups spend a larger share of their income on utility costs. The variation of energy consumption across income groups is related to household characteristics, characteristics of the dwellings, and cross-national differences in the housing sector. - Highlights: • We explain energy practices in Denmark, Austria, and the United Kingdom. • We show that income plays a central role in households’ energy practices. • High-income households have higher overall energy consumption. • Low-income groups spend a larger share of their income on utility costs. • Consumption depends on the household, dwelling and the housing sector

for the demand of the produced goods. Environmental priorities and targets for emission reductions are important for defining energy policy in Denmark. As the energy supply sector at present is a major contributor to emissions of CO2 and SO2, knowledge of this sector is vital for reducing these emissions......This paper examines structural change in the power and heat producing sector (energy supply) and its implications for the economy. An integrated approach is used to describe the interactions between this sector and the rest of the economy. Thus, a very detailed model of the sector for Denmark has...... been linked to a macroeconometric model of the Danish economy. It is argued that analysing sectors that undergo radical changes, for example, the energy supply sector should be undertaken by using a model that describes the technological and organisational changes in production along with implications...

ImSET: Impact of Sector Energy Technologies

Energy Technology Data Exchange (ETDEWEB)

Roop, Joseph M.; Scott, Michael J.; Schultz, Robert W.

2005-07-19

This version of the Impact of Sector Energy Technologies (ImSET) model represents the ''next generation'' of the previously developed Visual Basic model (ImBUILD 2.0) that was developed in 2003 to estimate the macroeconomic impacts of energy-efficient technology in buildings. More specifically, a special-purpose version of the 1997 benchmark national Input-Output (I-O) model was designed specifically to estimate the national employment and income effects of the deployment of Office of Energy Efficiency and Renewable Energy (EERE) -developed energy-saving technologies. In comparison with the previous versions of the model, this version allows for more complete and automated analysis of the essential features of energy efficiency investments in buildings, industry, transportation, and the electric power sectors. This version also incorporates improvements in the treatment of operations and maintenance costs, and improves the treatment of financing of investment options. ImSET is also easier to use than extant macroeconomic simulation models and incorporates information developed by each of the EERE offices as part of the requirements of the Government Performance and Results Act.

Today, the transport sector accounts for a quarter of the Sweden's energy consumption. As the transport sector is almost exclusively using fossil fuels, its conversion to other fuel-/energy types have a major impact in the coming years with the increasing requirements for reduced emissions of greenhouse gases. This situation is expected to change and expand requirements for statistics on the transport sector's energy use. Since 2008, as a result of the increased interest, the Swedish Energy Agency publish an annual collection of statistics for the transport sector.

Yukon energy sector assessment 2003 : final report

International Nuclear Information System (INIS)

Kishchuk, P.

2003-10-01

A study was conducted to better understand energy issues in the Yukon. The study was based on the Yukon Energy Matrix which looks at the Yukon energy sector from the perspective of the capacity to supply various forms of energy, the markets for energy in the Yukon, and energy users. The sources of non-renewable energy in the Yukon range from natural gas, coal and oil. Renewable energy sources are also diverse and include water, biomass, wind, solar and geothermal. The main sources of electricity production in the Yukon are oil, water and wind. The link between energy and climate change has gained much attention in recent years, resulting in effective measures to conserve energy and increase energy efficiency. Coal, gas and oil are imported into the Yukon from markets in southern Alaska despite the fact that Yukon has its own vast quantities of these fossil-based forms of energy. As a result, the price of fossil-fuels consumed in the Yukon is determined in national and international markets. The absence of non-renewable energy production in the Yukon is also reflected in the lack of pipeline and rail infrastructure in the territory. The Yukon's electricity transmission grid is also very fragmented. For the purpose of this paper, energy use was categorized into the residential, commercial, industrial and transportation sectors. 19 refs., 8 tabs., 12 figs

Sectoral shift in industrial natural gas demand: A comparison with other energy types

International Nuclear Information System (INIS)

Boyd, G.; Fisher, R.; Hanson, D.; Ross, M.

1989-01-01

It has been recognized in a variety of studies that energy demand by industry has been effected not only by the changing energy intensity of the various sectors of industry, but also by the composition of industrial sector. A previous study group of the Energy Modeling Forum (EMF-8) found that sectoral shift, i.e., the relative decline in the energy intensive sectors of industry, has contributed at least one third of the decline in aggregate manufacturing energy intensity since the early 1970s. The specific types of energy use may also be important, however. For example, the effect of shifts in production by electricity intensive sectors has been shown to be somewhat different than that for fossil fuel

Potential Evaluation of Energy Supply System in Grid Power System, Commercial, and Residential Sectors by Minimizing Energy Cost

Science.gov (United States)

Oda, Takuya; Akisawa, Atushi; Kashiwagi, Takao

If the economic activity in the commercial and residential sector continues to grow, improvement in energy conversion efficiencies of energy supply systems is necessary for CO2 mitigation. In recent years, the electricity driven hot water heat pump (EDHP) and the solar photo voltaic (PV) are commercialized. The fuel cell (FC) of co-generation system (CGS) for the commercial and residential sector will be commercialized in the future. The aim is to indicate the ideal energy supply system of the users sector, which both manages the economical cost and CO2 mitigation, considering the grid power system. In the paper, cooperative Japanese energy supply systems are modeled by linear-programming. It includes the grid power system and energy systems of five commercial sectors and a residential sector. The demands of sectors are given by the objective term for 2005 to 2025. 24 hours load for each 3 annual seasons are considered. The energy systems are simulated to be minimize the total cost of energy supply, and to be mitigate the CO2 discharge. As result, the ideal energy system at 2025 is shown. The CGS capacity grows to 30% (62GW) of total power system, and the EDHP capacity is 26GW, in commercial and residential sectors.

Documentation for Preservation: Methodology and a GIS Database of Three World Heritage Cities in Uzbekistan

Science.gov (United States)

Vileikis, O.; Escalante Carrillo, E.; Allayarov, S.; Feyzulayev, A.

2017-08-01

The historic cities of Uzbekistan are an irreplaceable legacy of the Silk Roads. Currently, Uzbekistan counts with four UNESCO World Heritage Properties, with hundreds of historic monuments and traditional historic houses. However, lack of documentation, systematic monitoring and a digital database, of the historic buildings and dwellings within the historic centers, are threatening the World Heritage properties and delaying the development of a proper management mechanism for the preservation of the heritage and an interwoven city urban development. Unlike the monuments, the traditional historic houses are being demolished without any enforced legal protection, leaving no documentation to understand the city history and its urban fabric as well of way of life, traditions and customs over the past centuries. To fill out this gap, from 2008 to 2015, the Principal Department for Preservation and Utilization of Cultural Objects of the Ministry of Culture and Sports of Uzbekistan with support from the UNESCO Office in Tashkent, and in collaboration with several international and local universities and institutions, carried out a survey of the Historic Centre of Bukhara, Itchan Kala and Samarkand Crossroad of Cultures. The collaborative work along these years have helped to consolidate a methodology and to integrate a GIS database that is currently contributing to the understanding of the outstanding heritage values of these cities as well as to develop preservation and management strategies with a solid base of heritage documentation.

Restructuring the industry sector - the impact on energy demand

Constantinescu, M.

1994-01-01

The structure of the industrial sector is a factor of major importance in analyzing the evolution of energy intensity or in setting-up realistic development scenarios. A positive influence on the energy intensity value is expected for Romania from the process of restructuring the industry sector towards low energy consumption products. In order to reach this target though, suitable end comprehensive strategies have to become operational without delay, promoting energy efficiency and modern technologies at a nation-wide scale. The benefits of such strategies extend from improvement of the security of supply through environmental protection and reduction of unemployment. (Author)

The single European energy market: the electricity supply sector

The completion of the Internal Market in the Community by the end of 1992 has become a key objective and the focal point of the revival of the European Community. Within this overall objective, the development of the Single European Energy Market, the Internal Energy market, is a major element. The energy objectives for the Community, adopted in 1986 by the Council of Ministers and relating to targets in the energy sector to be achieved by 1995, contain what are effectively the aims of the Internal Energy Market. This is in a reference to the need for greater integration, free from barriers to trade, of the Internal Energy Market with a view to improving security of supply, reducing costs and improving economic competitiveness. In the light of these aims, the Commission drew up, in 1988, an inventory of potential obstacles to the achievement of the Internal Energy Market. This was accepted by the Council, together with a list of suggested priority areas of work, and has formed the basis of the Commission's efforts to move forward as quickly as possible in the development of the Internal Energy Market, in all branches of the energy sector. The impact on the electricity sector, in particular, is considered here. (author)

Hippel, David von; Hayes, Peter

2011-01-01

The goal of international negotiations with the Democratic People's Republic of Korea (DPRK), when they begin again, will be to convince the DPRK to give up its nuclear weapons and the capabilities to produce them. The DPRK's energy sector is a key to resolution of the issue. Thus offering a well-considered, well-structured package of energy sector assistance options will be key to the sustainable success of the negotiations. This article briefly reviews some of the key options for DPRK energy assistance ranging from human capacity-building in fields like energy efficiency, renewable energy, and energy markets, to assistance with rebuilding key electricity and coal mining infrastructure, to integrated pilot energy/electricity grid/economic development projects on the county level, to light-water nuclear reactors. It then reviews preferences for DPRK assistance options as offered by North Koreans, and a summary of the likely points of view of the key DPRK actors that will be involved in negotiations.

Impact of Institutional Change on Irrigation Management: A Case Study from Southern Uzbekistan

Directory of Open Access Journals (Sweden)

Kakhramon Djumaboev

2017-06-01

Full Text Available The rapidly growing population in Uzbekistan has put massive pressure on limited water resources, resulting in frequent water shortages. Irrigation is by far the major water use. Improving irrigation water use through the institutional change of establishing water consumer associations (WCAs has been identified as a way to increase agricultural production and meet the food demand in the area. However, most WCAs are not fully able to organize collective action or generate sufficient funds to carry out their responsibilities. This study investigated the water-resource-related challenges faced by WCAs and local farmers in Kashkadarya Province in Uzbekistan, using semi-structured expert interviews and focus group discussions. The resulting data were analyzed using qualitative analysis software (Atlas.ti. The results indicated that outdated infrastructure, poor governance, and farmers’ non-payment of irrigation service fees hamper sustainable water management. Greater trust and communication within the WCAs would make an important contribution to effective collective action and to the long-term sustainability of local associations.

Substitution between energy and classical factor inputs in the Chinese steel sector

Smyth, Russell; Narayan, Paresh Kumar; Shi, Hongliang

2011-01-01

China's steel sector is the largest in the world and has been a major driving force behind China's high rate of economic growth. This sector, however, is also a major consumer of energy and, in particular, coal. As a result, the iron and steel sector in China is a major contributor to greenhouse gas emissions and other pollutants. In this article we examine the potential for inter-factor substitution between capital, energy and labor in the Chinese steel sector and find that capital and energy and energy and labor are substitutes. This result suggests that removal of price ceilings on energy would tend to reduce energy use and increase capital intensiveness. While the potential for substitution between energy and labor is less than that between energy and capital, the elasticity of substitution between energy and labor is high compared with previous findings for other countries. This fact suggests that there may be potential for substituting labor for energy, given China's abundance of labor.

Market leadership by example: Government sector energy efficiency in developing countries

Government facilities and services are often the largest energy users and major purchasers of energy-using equipment within a country. In developing as well as industrial countries, government ''leadership by example'' can be a powerful force to shift the market toward energy efficiency, complementing other elements of a national energy efficiency strategy. Benefits from more efficient energy management in government facilities and operations include lower government energy bills, reduced greenhouse gas emissions, less demand on electric utility systems, and in many cases reduced dependence on imported oil. Even more significantly, the government sector's buying power and example to others can generate broader demand for energy-efficient products and services, creating entry markets for domestic suppliers and stimulating competition in providing high-efficiency products and services. Despite these benefits, with the exception of a few countries government sector actions have often lagged behind other energy efficiency policies. This is especially true in developing countries and transition economies - even though energy used by public agencies in these countries may represent at least as large a share of total energy use as the public sector in industrial economies. This paper summarizes work in progress to inventory current programs and policies for government sector energy efficiency in developing countries, and describes successful case studies from Mexico's implementation of energy management in the public sector. We show how these policies in Mexico, begun at the federal level, have more recently been extended to state and local agencies, and consider the applicability of this model to other developing countries.

Turkey, an alley of the West, and being in the process of rapid integration with the world economy, has started a comprehensive restructuring endeavor in the energy sector. In today's power markets where globalisation and competition plays an increasing role, supply security, economic growth and social targets must be harmonized effectively. Following topics can be considered as basic instruments in this context; restructuring of the power sector (privatization, demonopolization); removal of governmental intervention in the markets; creating a better regional/global cooperation for the deployment of new technologies; enhancing energy efficiency.

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 critical terrorist threat assessment of Canadian energy systems was presented, as well as an analysis of integrated continental systems.

The purpose of this work is to apply the useful energy and exergy analysis models for different modes of transport in Malaysia and to compare the result with a few countries. In this paper, energy and exergy efficiencies of the various sub-sectors are presented by considering the energy and exergy flows from 1995 to 2003. Respective flow diagrams to find the overall energy and exergy efficiencies of Malaysian transportation sector are also presented. The estimated overall energy efficiency ranges from 22.74% (1999) to 22.98% (1998) with a mean of 22.82+/-0.06% and that of overall exergy efficiency ranges from 22.44% (2000) to 22.82% (1998) with a mean of 22.55+/-0.12%. The results are compared with respect to present energy and exergy efficiencies in each sub-sector. The transportation sector used about 40% of the total energy consumed in 2002. Therefore, it is important to identify the energy and exergy flows and the pertinent losses. The road sub-sector has appeared to be the most efficient one compared to the air and marine sub-sectors. Also found that the energy and exergy efficiencies of Malaysian transportation sector are lower than that of Turkey but higher than Norway

Hooker, J.N.; Rose, A.B.; Greene, D.L.

1980-02-01

The transportation fuel and energy use estimates developed a Oak Ridge National Laboratory (ORNL) for the End Use Energy Consumption Data Base are documented. The total data base contains estimates of energy use in the United States broken down into many categories within all sectors of the economy: agriculture, mining, construction, manufacturing, commerce, the household, electric utilities, and transportation. The transportation data provided by ORNL generally cover each of the 10 years from 1967 through 1976 (occasionally 1977 and 1978), with omissions in some models. The estimtes are broken down by mode of transport, fuel, region and State, sector of the economy providing transportation, and by the use to which it is put, and, in the case of automobile and bus travel, by the income of the traveler. Fuel types include natural gas, motor and aviation gasoline, residual and diesel oil, liuqefied propane, liquefied butane, and naphtha- and kerosene-type jet engine fuels. Electricity use is also estimated. The mode, fuel, sector, and use categories themselves subsume one, two, or three levels of subcategories, resulting in a very detailed categorization and definitive accounting.

Nuclear medicine in Uzbekistan and current status of radionuclide therapy in the country

Rasulova, N.; Khodjibekova, M.

2005-01-01

Full text: The population of Uzbekistan is 26 million and to cater to this population we have only two nuclear medicine departments; one at the Clinical Centre for Surgery and the other at the Institute of Endocrinology, both situated in Tashkent, the capital city of Uzbekistan. Over the years through its own initiatives and through the support provided by several International Organizations including the IAEA, Uzbekistan has been able to marginally improve its nuclear medicine services. SPECT imaging was introduced through generous support from IAEA in the year 2001. As a result of this, the country is now able to provide modern in vivo nuclear medicine service to the population in a limited scale. At the Clinical Centre for Surgery we are able to provide gamma camera and SPECT imaging services to patients suffering from various nephro-urological, cardiac, neuro and oncological disorders. The other nuclear medicine centre at the Institute of Endocrinology does not have any modern imaging system. However it has been engaged in providing radionuclide therapy service for thyroid diseases like thyroid cancer and hyperthyroidism. From the year 1983 to 1999 the country has reported a total number of 6374 cases of Thyroid Cancer. This number is growing each year, for example the incidence of thyroid cancer in 1989 was 1.95 per 100,000, which has grown to 2.39 per 100,000 in 1999. While the Institute of Endocrinology provides therapeutic service to thyroid diseases, the main role of the Nuclear Medicine Department of Republic Specialized Center of Surgery is in following-up of patients after therapy by performing large dose I-131 whole body imaging, screening for metastases and for assessment of results of radioactive iodine therapy. Besides treating thyroid diseases with I-131 limited services are also available for treatment of polycythemia vera rubra with P-32 and radionuclide therapy for metastatic bone pain. Radionuclide therapy is growing rapidly around the world

Investing in the Energy Sector: An Issue of Governance

International Nuclear Information System (INIS)

Horst Keppler, J.; Schulke, Ch.

2009-01-01

Of all economic sectors, energy is among those where the issue of investments is the most urgent. Because of its technological structure and significant fixed costs, the energy sector is by nature heavily capital intensive. With growing demand and increasingly difficult access to resources, the amounts needed become enormous. The International Energy Agency (IEA) estimates in its World Energy Outlook 2008 that total energy investment needs between now and 2030 will stand at $26 trillion, or close to $1 trillion per year. This is just for energy supply. Half of these investments will be needed in the electricity sector (see below for more details on these estimations). Even after putting these figures into perspective in terms of total worldwide investments over the next 25 years, the amount of money is still significant. All types of energy are involved - oil, gas, coal, nuclear and renewables. In addition, all steps in the supply chain are included - exploration, production, transformation and transportation. The stakes are high. Without the necessary investments, security of supply, global economic growth and environmental integrity are put at risk. The most important challenge for the energy sector in the years to come is thus to pave the way for realising timely and appropriate investments. The current economic recession that is threatening to curb global economic growth will not change this fact. Even if global energy demand slows down in the next two or three years, the world will return to its long term growth path. An energy facility lasts between 20 and 60 years. Thus, the structure of energy production in 2050, when the current economic crisis has been forgotten, will be determined now and over the next years. Even if global energy demand remains stable between now and 2050 (which is highly improbable), the replacement of existing facilities that have reached the end of their life-cycle will still require considerable efforts.

Saidur, R.; Masjuki, H.H.; Jamaluddin, M.Y.

2007-01-01

In this paper, the useful concept of energy and exergy utilization is defined, analyzed and applied to the residential sector of Malaysia by taking into account the energy and exergy flows for a period of 8 years from the year 1997 to 2004. The energy and exergy efficiencies are determined for the devices used in this sector and found to be 70% and 28%, respectively. Energy and exergy flow diagrams for the overall efficiencies of Malaysian residential sector are also illustrated in this paper. It is found that the current methodology applied in Saudi Arabia is suitable to analyze energy and exergy use in Malaysian residential sector. It has been found that the exergy efficiency of the Malaysian residential sector appears to be much lower than its corresponding energy efficiency. It has been observed that about 21% of total exergy losses are caused by refrigerator-freezer and 12% of total loss is caused by air conditioner. Washing machine, fan and rice cooker contribute about 11%, 10% and 8% of total exergy losses, respectively

Danish energy-sector exports. Products and consulting services

Danish Energy Agency has previously carried out studies of Danish energy-sector exports. The latest results were published in the report, Energisektorens eksport. Produkter og raadgivning. Danish Energy Agency, September 1998. The present survey is an update of the earlier studies, and includes 1998 exports. As previously, the study, carried out in cooperation with the Confederation of Danish Industries and the Danish Council of Consulting Architects and Engineers, is based on questionnaires sent to relevant companies. In addition, information has been obtained from companies that do not belong to these organisations. On the basis of the answers received, 58 Danish companies exported products to a value of approximately DKK 16,000 million, and 22 consulting firms exported consulting services to a value of approximately DKK 370 million. These exports of approximately DKK 16.5 billion accounted for 5% of all Danish exports in 1998. In comparison with 1996, energy-sector exports have risen by more than 40% in a period in which Danish exports in general have risen by an average of 8%. Energy sector exports provide employment for more than 18,000 persons in Denmark - approximately 17,500 employees in companies that export products, and approximately 600 persons in consulting firms. To this must be added a presumably significantly larger number of persons employed by sub-suppliers to the above companies computed by value, 80% of the exports come from relatively few companies, i.e. 13 companies with products, and five offering consulting services. Energy-sector exports fall within the following product areas: 1) Wind turbines (25%). 2) District heating and combined heat and power (CHP) (21%). 3) Energy savings and control (20%). 4) Oil and natural gas (13%). 5) Electricity plants and power supply (13%). 6) Other (8%). 67% of the exports go to Western Europe, 18% to Asia, 7% to Eastern and Central Europe, and 8% to other parts of the world.

Wind energy in the agricultural sector. Tailwind or head wind?

International Nuclear Information System (INIS)

Van der Knijff, A.

1999-06-01

The state of the art in the use of wind energy in the agricultural sector in the Netherlands is given in order to map opportunities. Obstacles to expansion of wind capacity in that sector in the short term are described, as well as the most important developments with respect to wind energy. An estimated 275 wind turbines with a capacity of 50 MW are in use in the Netherlands. This means that the agricultural sector accounts for approximately 14% of the total wind capacity in the Netherlands (363 MW in 1998). Most of the agricultural businesses supply all the electricity generated to the public networks. Only a small number of farmers use some of the generated electricity themselves. The most important obstacles for the agrarian sector are the proposed policies of provinces and municipalities, the limited capacity of the public electricity network, and the lack of clarity regarding the liberalisation of the electricity market. In particular, provincial and municipal policies (solitary wind turbines versus wind farms) will determine the prospects for the future of wind energy in the agrarian sector. Despite possible adversities, there are good prospects for the future for the sector because farmers own land in windy locations. 33 refs

Modern economies have been subjected to a number of shocks during the past several years such as the burst of the Internet bubble, terrorist attacks, corporate scandals, the war in Iraq, the uncertainty about energy prices, and the recent subprime mortgage crisis. In particular, during the last few years, the energy shock has caused concerns for potential stagflation for both the United States and numerous other countries. We perform numerous univariate tests for non-linearity and chaotic structure using price data from the energy sector to resolve whether the sector's fundamentals or exogenous shocks drive these prices.

DOCUMENTATION FOR PRESERVATION: METHODOLOGY AND A GIS DATABASE OF THREE WORLD HERITAGE CITIES IN UZBEKISTAN

Directory of Open Access Journals (Sweden)

O. Vileikis

2017-08-01

Full Text Available The historic cities of Uzbekistan are an irreplaceable legacy of the Silk Roads. Currently, Uzbekistan counts with four UNESCO World Heritage Properties, with hundreds of historic monuments and traditional historic houses. However, lack of documentation, systematic monitoring and a digital database, of the historic buildings and dwellings within the historic centers, are threatening the World Heritage properties and delaying the development of a proper management mechanism for the preservation of the heritage and an interwoven city urban development. Unlike the monuments, the traditional historic houses are being demolished without any enforced legal protection, leaving no documentation to understand the city history and its urban fabric as well of way of life, traditions and customs over the past centuries. To fill out this gap, from 2008 to 2015, the Principal Department for Preservation and Utilization of Cultural Objects of the Ministry of Culture and Sports of Uzbekistan with support from the UNESCO Office in Tashkent, and in collaboration with several international and local universities and institutions, carried out a survey of the Historic Centre of Bukhara, Itchan Kala and Samarkand Crossroad of Cultures. The collaborative work along these years have helped to consolidate a methodology and to integrate a GIS database that is currently contributing to the understanding of the outstanding heritage values of these cities as well as to develop preservation and management strategies with a solid base of heritage documentation.

This paper introduces an integrated approach based on data envelopment analysis (DEA), principal component analysis (PCA) and numerical taxonomy (NT) for total energy efficiency assessment and optimization in energy intensive manufacturing sectors. Total energy efficiency assessment and optimization of the proposed approach considers structural indicators in addition conventional consumption and manufacturing sector output indicators. The validity of the DEA model is verified and validated by PCA and NT through Spearman correlation experiment. Moreover, the proposed approach uses the measure-specific super-efficiency DEA model for sensitivity analysis to determine the critical energy carriers. Four energy intensive manufacturing sectors are discussed in this paper: iron and steel, pulp and paper, petroleum refining and cement manufacturing sectors. To show superiority and applicability, the proposed approach has been applied to refinery sub-sectors of some OECD (Organization for Economic Cooperation and Development) countries. This study has several unique features which are: (1) a total approach which considers structural indicators in addition to conventional energy efficiency indicators; (2) a verification and validation mechanism for DEA by PCA and NT and (3) utilization of DEA for total energy efficiency assessment and consumption optimization of energy intensive manufacturing sectors

Thermodynamic losses usually take place in machineries used for agricultural activities. Therefore, it is important to identify and quantify the losses in order to devise strategies or policies to reduce them. An exergy analysis is a tool that can identify the losses occurred in any sector. In this study, an analysis has been carried out to estimate energy and exergy consumption of the agricultural sector in Malaysia. Energy and exergy efficiencies have been determined for the devices used in the agricultural sector of Malaysia, where petrol, diesel and fuel oil are used to run the machineries. Energy and exergy flow diagrams for the overall efficiencies of Malaysian agricultural sector are presented as well. The average overall energy and exergy efficiencies of this sector were found to be 22% and 20.728%, respectively, within the period from 1991 to 2009. These figures were found to be lower than those of Norway but higher than Turkey. - Highlights: ► Highest exergy efficiency was found about 20.7% for the year 2007. ► The exergy efficiency of the agro-sector in Malaysia was lower than that of energy efficiency. ► It was also found that this sector of Malaysia is less efficient than Saudi Arabia and Norway. ► Energy and exergy losses were identified through this analysis. ► Part of the losses can be reduced using appropriate technology, management and policy.

The U.S. government, along with other governments, private corporations and organizations, invests significantly in research, development, demonstration and deployment (RDD&D) activities in clean energy technologies, in part to achieve the goal of a clean, secure, and reliable energy system. While specific outcomes and breakthroughs resulting from RDD&D investment are unpredictable, it can be instructive to explore the potential impacts of clean energy RDD&D activities in the power sector and to place those impacts in the context of current and anticipated market trends. This analysis builds on and leverages analysis by the U.S. Department of Energy (DOE) titled “Energy CO₂ Emissions Impacts of Clean Energy Technology Innovation and Policy” (DOE 2017). Similar to DOE (2017), we explore how additional improvements in cost and performance of clean energy technologies could impact the future U.S. energy system; however, unlike the economy-wide modeling used in DOE (2017) our analysis is focused solely on the electricity sector and applies a different and more highly spatially-resolved electric sector model. More specifically, we apply a scenario analysis approach to explore how assumed further advancements in clean electricity technologies would impact power sector generation mix, electricity system costs, and power sector carbon dioxide (CO₂) emissions.

Africa's energy sector: energy availability and the underlying financial challenges

Lebesa, Motselisi; Ndyeshobola, Ahmed.

1994-01-01

The objective of this paper is to provide a brief overview of energy availability in Africa and the attendant financing concerns in the African energy sector. The paper departs from three key premises: firstly that energy resources in Africa are abundant, but current trends in its consumption and inherent externalities are unsustainable. This abundance is also affected by social and political stability. Secondly, that the majority of Africa's population lacks access to adequate energy services. Poverty issues and effects undermine the urgency of energy and environmental concerns. Thirdly, that Africa's sustainable development calls for more energy supply not less. Future energy requirements and related supply and financing issues are discussed with the time horizon of the year 2020. (author)

Nuclear energy and opportunity to strengthen the sustainable electricity sector

International Nuclear Information System (INIS)

Robles N, A. G.

2016-09-01

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

Residential sector is the core among the energy demand sectors in Pakistan. Currently, various techniques are being used worldwide to assess future energy demands including integrated system modeling (ISM). Therefore, the current study is focused on implementation of ISM approach for future energy demand analysis of Pakistan's residential sector in terms of increase in population, rapid urbanization, household size and type, and increase/decrease in GDP. A detailed business-as-usual (BAU) model is formulated in TIMES energy modeling framework using different factors like growth in future energy services, end-use technology characterization, and restricted fuel supplies. Additionally, the developed model is capable to compare the projected energy demand under different scenarios e.g. strong economy, weak economy and energy efficiency. The implementation of ISM proved a viable approach to predict the future energy demands of Pakistan's residential sector. Furthermore, the analysis shows that the energy consumption in the residential sector would be 46.5 Mtoe (Million Ton of Oil Equivalent) in 2040 compared to 23 Mtoe of the base year (2007) along with 600% increase in electricity demands. The study further maps the potential residential energy policies to congregate the future demands. (author)

The ability to use a whole-building simulation tool to model the entire sector is of interest because the energy models enable us to answer subsequent 'what-if' questions that involve technologies and practices related to energy. This report documents how the whole-building models were generated from the building characteristics in 2003 CBECS and compares the simulation results to the survey data for energy use.

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.

Financing the energy sector in developing countries: context and overview

International Nuclear Information System (INIS)

Dunkerley, Joy.

1995-01-01

Traditional 'business as usual' financing methods will no longer be adequate to meet the unprecedented demands for capital to finance energy sector expansion in the developing countries. In recognition, many countries are opening up their power sectors to private investment, initially through the establishment of independent power projects, but in some cases through sector privatization. Project financing has many advantages, but further sectoral reorganization, including tariff reform, will be needed to attract resources on the scale required, especially from domestic investors. In oil and gas, in contrast to power, private capital from the international oil companies has always played a major role in the developing countries. However, sharply increasing investment requirements require a growing role for external finance. There should, in principle, be no shortage of investible funds to finance energy sector expansion in developing countries so long as host countries establish conditions which are attractive to private investors. The augmented role of private finance requires a continuing, if different, role for the public sector in both host countries and official aid agencies. (author)

Energy Efficiency Sector in Russia. Market Survey of Equipment and Services

International Nuclear Information System (INIS)

2006-02-01

The aim of the present Survey is to give an insight of energy efficiency (EE) in Russia and to assess the demand for EE equipment and services in the energy sector. In the Survey the term 'Energy Efficiency' means the efficient generation, distribution and consumption of heat and power. The main EE measures are classified as recovery of sources of energy, measuring and controlling systems, optimal use of the equipment, modernisation, in-house energy generation and renewable energy sources. Chapter 3 gives an overview of the current situation of the Russian energy sector. The term 'energy sector' is used in the context of generation, distribution and consumption of heat and power. The infrastructure and the ownership of the energy sector are examined. In this chapter special attention is paid to the Power Sector Reform and how the Reform affects the development of EE in the Russian energy sector. Chapter 4 describes the current situation in EE, giving the reasons of inefficiency in energy use and possible solutions for improving. Chapter 5 presents a market research of equipment that could make a great input into EE development. The research has shown that the most promising opportunities for suppliers of EE equipment lie in the heat sector (generation, distribution, consumption). This chapter also describes the development of ESCOs (Energy Service Companies) in Russia. Chapter 6 gives an overview of domestic and foreign capital available to finance EE development. According to conventional market based incentives, end users invest into increasing their profits more intensively than into projects aiming at energy saving. That is mostly because energy is relatively cheap in Russia and the federal governmental policy does not stimulate EE development either. Chapter 7 on the market approach advises on steps that have to be taken and risks that need to be avoided in order to enter the Russian market successfully. It warns of the possible pitfalls on this way. Chapter 8

As energy demand and prices continue to grow, oil shale might help mitigate the energy crisis—it can widely be found all over the world but so far has not been widely used. Estonia is unique in the world for producing a large majority of energy out of oil shale and has been set as an example in numerous papers covering oil shale deposits, technology etc. This paper is the first to analyse oil shale energy related workforce and provides scenario forecasts of the labour demand for the Estonian energy sector in 2010–2020. The contribution of the paper is twofold. First, the paper provides a valuable insight into oil shale energy related workforce, enabling to take into consideration the educational needs in countries where oil shale industry might be set up. Second, methodology-wise, the paper relates labour demand and supply to different scenarios of energy production capacities. The results illustrate problems related to aging of the workforce in energy production. If the existing trends continue in educational attainment in Estonia, there will be a serious shortage of high-skilled engineering and manufacturing specialists. Our method provides a simple yet reliable enough way to check for such problems early enough. - Highlights: ► This paper analyses oil shale energy related workforce and provides scenario forecasts. ► This is the first study to investigate the workforce related to oil shale energy production. ► The main workforce-related problem in the sector is ageing of the workforce. ► Workers immigrating to the sector during the Soviet times are at the retirement age. ► There will be a serious shortage of engineers for energy sector in the near future.

Cross-border versus cross-sector interconnectivity in renewable energy systems

International Nuclear Information System (INIS)

Thellufsen, Jakob Zinck; Lund, Henrik

2017-01-01

In the transition to renewable energy systems, fluctuating renewable energy, such as wind and solar power, plays a large and important role. This creates a challenge in terms of meeting demands, as the energy production fluctuates based on weather patterns. To utilise high amounts of fluctuating renewable energy, the energy system has to be more flexible in terms of decoupling demand and production. This paper investigates two potential ways to increase flexibility. The first is the interconnection between energy systems, for instance between two countries, labelled as cross-border interconnection, and the second is cross-sector interconnection, i.e., the integration between different parts of an energy system, for instance heat and electricity. This paper seeks to compare the types of interconnectivity and discuss to which extent they are mutually beneficial. To do this, the study investigates two energy systems that represent Northern and Southern Europe. Both systems go through three developmental steps that increase the cross-sector interconnectivity. At each developmental step an increasing level of transmission capacities is examined to identify the benefits of cross-border interconnectivity. The results show that while both measures increase the system utilisation of renewable energy and the system efficiency, the cross-sector interconnection gives the best system performance. To analyse the possible interaction between cross-sector and cross-border interconnectivity, two main aspects have to be clarified. The first part defines the approach and the second is the construction of the two archetypes. - Highlights: • A method to investigate system integration and system interconnection is suggested. • The implementation is investigated across a Northern and Southern energy system. • The study identifies benefits of system integration and system interconnection. • The performance of the energy system benefits most from system integration.

Yakovlev, A.F.; Petrov, V.N.; Chupyatov, V.P.

1996-12-31

This paper describes the mitigation potential in the Russian energy sector and presents CO{sub 2} - emission scenarios. Based on the Russian energy strategy, energy conservation potential has been estimated and three groups of energy conservation measures have been pointed out. Taking into account the economic development scenarios and the scenarios of energy consumption and energy conservation, future CO{sub 2} emission scenarios for 2000 and 2010 have been prepared. Some important characteristics of these scenarios have been presented and discussed. For the period 2000-2010 annual growth rates for CO{sub 2} emission in the Russian energy sector will not exceed 0.9-1.3 %, and emission levels in 2000 make up - 75-78 %, and in 2010 - 81-88 % of the 1990 level. For the probable scenario the CO{sub 2} emission reducing will make up about 6% and 25% (for the optimistic scenario about 16% and 31%) of CO{sub 2} emission for reference scenario in 2000 and 2010 respectively. Additional CO{sub 2} emission reducing (3-5% of domestic CO{sub 2} emission) will result from increasing share of natural gas consumption.

Sectorial energy observatory: the concentration of the sector intensifies

International Nuclear Information System (INIS)

2000-01-01

The 1998 energy market conjuncture was particularly bad for two main reasons: the collapse of oil prices and the recession of primary energy consumption. This situation occurred while the regulatory framework of markets was becoming overturned because of the forthcoming deregulation of the European power market (February 1999) and of the natural gas market (summer 2000). In this context, the energy actors have concentrated their efforts to the reinforcement of their positions using external growth operations. Apart from the concentration process, the actors of the energy sector have carried on with their strategic initiatives started these last years, internationalization being their main strategic goal. Europe is their favoured zone but they more and more lust after the USA: oil companies are placing their positions downstream of the gas industry file, while gas distributors are moving upstream. The financial performances of energy actors have been greatly lowered with a general decreasing turnover (negative price effect). They have kept some important financial latitude in order to maintain their concentration policy. Their targets will be probably the German, British and Spanish electricity and gas utilities. The electric power sector has been one of the main sectors concerned by external growth operations, but the natural gas industry should encounter a similar evolution since summer 2000. (J.S.)

Carrying out an information-orientation plan in the energy sector is indispensable if Korea is to survive in this unlimited competition age and global management system. It is also for maximizing the management efficiency of national energy resources as well as increasing the development of related industries and national welfare. The management of the energy resources sector of Korea, which is becoming diversified escaping from the past simple quantitative management of supplier-orientation, requires versatile and ample high-class information management system and high-level decision support system. In order to satisfy these requests, this study investigated and analyzed overall policies of the energy sector for carrying out information-orientation, neighborhood environment, organizational chart, information transfer method, the current condition of information-orientation, problems and improvements, demand of information-orientation of the future, and also reviewed the information-orientation status of advanced countries. Based on these, an information-orientation carryout plan in the energy sector is broken into three stages of `establishment of information transfer system`, `development of database`, and `establishment of decision support system` and presented per detailed work. It advised manpower, equipment and budget implementation plan, and a development schedule plan required for carrying out information-orientation as well as overall environmental build-up, and policy recommendation for the successful implementation of information-orientation. 24 refs., 27 figs., 15 tabs.

Highlights: • The energy and exergy use in China’s urban residential sector between 2002 and 2011 are analyzed. • The primary locations and causes of energy and exergy losses in the CURS are identified. • The large gap between the energy and exergy efficiencies implies great potential for energy saving. • The exergy utilization can be improved by using appropriate technology, management and policy. - Abstract: In this paper, the energy and exergy utilizations in the Chinese urban residential sector (CURS) are analyzed by considering the energy and exergy flows for the years between 2002 and 2011. The energy and exergy efficiencies of this sector are calculated to examine the potential for advancing the ‘true’ energy efficiency and determine the real energy losses. The results demonstrate large differences between the overall energy efficiencies (62.8–70.2%) and the exergy efficiencies (11.0–12.2%) for the years analyzed. The sizable gap between the energy and exergy efficiencies implies a high potential for energy savings in the CURS. Future energy saving strategies should pay more attention to the improvement in exergy efficiencies. Moreover, it is found that direct fuel use constituted the primary exergy losses of the CURS; coal-fired boiler heating systems cause approximately 35% of the total exergy losses. Gas stoves, cogeneration systems, coal stoves and gas water heaters constitute 15.3%, 15%, 5.5% and 4.9% of the total exergy losses, respectively

Energy efficiency and restructuring of the Brazilian power sector

Since the early nineties Brazil has initiated a program of reforms in its electric sector which includes utility privatization, de-verticalization. The main objectives were to promote a market-oriented energy industry attractive to private investments. This has led to the loss of sponsorship for the public-interest programs formerly undertaken by the state utilities. In particular, of significant concern are the programs for promotion of energy efficiency, renewable energy technologies, rural electrification and environmental protection. In the midst of the privatization effort, the National Agency for Electrical Energy ANEEL was created (end of 1997). One of the tasks of the regulatory agency is to provide funds and incentives to energy conservation. In this paper we review the role of ANEEL in promoting energy efficiency investments in the context of a market-oriented sector, its limitations and prospects. [Spanish] Desde principios de los anos noventa Brasil ha iniciado un programa de reformas en su sector electrico que incluye la privatizacion del servicio electrico y la desverticalizacion. Los objetivos principales eran promover una industria de la energia orientada comercialmente de la energia electrica, atractiva a las inversiones privadas. Esto ha conducido a la perdida de patrocinio de los programas de interes publico emprendidos antes por las empresas electricas del estado. En particular, de preocupacion significativa estan los programas para la promocion del rendimiento energetico, de las tecnologias de la energia renovable, de la Electrificacion rural y de la proteccion del medio ambiente. En medio del esfuerzo de la privatizacion, la agencia nacional para la energia electrica ANEEL fue creada (finales de 1997). Una de las tareas de la agencia reguladora es proporcionar fondos e incentivos a la conservacion de energia. En este trabajo repasamos el papel de ANEEL en promover inversiones del rendimiento energetico en el contexto de un sector orientado

Why is energy use rising in the freight sector?

International Nuclear Information System (INIS)

Mintz, M.; Vyas, A.D.

1991-01-01

Trends in transportation sector energy use and carbon dioxide emissions are analyzed with an emphasis on three freight modes -- rail, truck, and marine. A recent set of energy use projections is presented and freight mode energy characteristics are discussed. Transportation sector energy use, which nearly doubled between 1960 and 1985, is projected to grow more slowly during the period 1985 endash 2010. Most of the growth is projected to come from non-personal modes (freight and commercial air). Trends in freight mode energy intensities are discussed and a variety of factors behind these trends are analyzed. Rail and marine modes improved their energy intensities during sudden fuel price rises of the 1970s. Though there is room for further technological improvement, long power plant life cycles preclude rapid penetration of new technologies. Thus, energy intensities in these modes are more likely to improve through operational changes. Because of relatively stable fuel prices, the energy share of truck operating expenses is likely to remain low. Coupled with increasing labor costs, this portends only modest improvements in truck energy efficiency over the next two decades

It also shows the main factors influencing energy consumption; limitations in energy sector development deriving from climate changes and environment preservation; technological development and its impact on the energy sector development; potentials of available resources and energy infrastructure for energy transport/transmission and energy import, as well as the security and quality of supply. The paper highlights significant changes in the energy sector, necessity of developing new economic policies which would be based on enhancing energy efficiency and use of low CO 2 and GHG technologies or use of those technologies which contribute to substantial reduction of the emissions.(author).

Model projections and policy reviews for energy saving in China's service sector

International Nuclear Information System (INIS)

Zhang, Lin

2013-01-01

Energy efficiency of buildings in the service sector is becoming increasingly important in China due to the structural shift of the economy from industry to services. This paper employs a bottom-up cohort model to simulate current energy saving policies and to make projections for future energy use and CO 2 emissions for the period 2000–2030 in the Chinese service sector. The analysis shows that energy demand in the service sector will approximately triple in 2030, far beyond the target of quadrupling GDP while only doubling energy use. However, it is feasible to achieve the target of emission reduction by 40% in 2020 even under the poor state of compliance rate of building standard. This paper also highlights four crucial aspects of designing optimal energy saving policies for China's service sector based on the model results. - Highlights: • Government energy saving target cannot realize with current policies in services. • Energy savings policies for new buildings are crucial than building retrofitting. • Cooling energy use increases significantly to reach equal weight as heating. • CO 2 tax can contribute to change in fuel mix, and thus emission reductions. • Low compliance rate limits further energy saving, hence green fund is required

Full Text Available Strengthening the influence of India in the Asian region and in the world requires for resorting of the modernization experience of this country, including the development of its energy sector. India today is among the top ten countries to generate electricity per capita. At the same time, both traditional sources of energy production coexist in India (using the muscular strength of man and animals with the conditions for the development of modern energy infrastructure through foreign investments. The article attempts to trace the main stages of the formation and development of energy industry in India; the modern state of energy is analyzed and plans for its development are considered. The research is based on a complex of traditional methods and approaches based on the principle of scientific objectivity and systemic method used in research in the framework of international relations and political science. For more than a century of history of the development of energy sector in India significant success has been achieved. Starting with the electrification of large cities and industrial enterprises due to foreign investments in the colonial period, India, after gaining the independence, set the task of developing its own infrastructure, electrifying the countryside and providing the industry with energy resources. The greatest progress in the development of electric power and nuclear energy was made. Indian economic growth will increase India’s energy needs and quadruple the demand for electricity over the next 25 years. For this, India needs to solve the problems of energy efficiency, energy complex management, lack of standards and energy imports, as well as actively introduce alternative energy sources and move to clean electricity (increased use of water resources and solar energy, which can be done through the development of Russian -Indian cooperation.

Account for sector heterogeneity in China's energy consumption. Sector price indices vs. GDP deflator

International Nuclear Information System (INIS)

Ma, Chunbo

2010-01-01

A common practice in decomposition analyses is to deflate output indicators to purge the impact of inflation by using a general deflator. This practice fails to account for sector heterogeneity and can be hazardous. Although the general identified patterns are largely correct, the calculated magnitudes can be misleading or even wrongly signed. Instead, it is strongly recommended that sector heterogeneity is accounted for by using individual sector price indices for all relevant sectors instead of one general (GDP) deflator. This paper analyzes this advanced decomposition using Chinese data and compares to the usual method of using only one deflator. It is found that while most differences are only of quantitative quality, some show even a qualitative difference. Furthermore, the rising energy intensity in the early 2000s, which has been discussed by previous studies, vanishes completely. (author)

Cystic echinococcosis (CE) is one of the most widespread zoonotic helminthiases, which can last an asymptomatic infection for several years. The purpose of this study was to demonstrate serum antibody prevalence of CE among asymptomatic people in Uzbekistan using ELISA. A total of 2,547 serum samples were collected, 66 from confirmed CE patients and 2,481 of patients with other diseases than CE at a hospital in Tashkent, Uzbekistan. The serum samples were screened for CE specific IgG antibodies by ELISA using cystic fluid antigen obtained from sheep. The serum antibody positive rate was 89.4% (59/66) in CE and 3.6% (89/2,481) in other disease patients. The present ELISA recognized 89.4% sensitivity and 96.4% specificity. The ELISA absorbance of positive samples was distributed 0.271-0.971 for CE and 0.273-0.887 for other disease patients. The other disease patients with high absorbance over 0.3 were 50 (2.0%) who were presumed to be active CE patients. The patients in their 40s showed the highest positive rate of 5.2% (P=0.181), and women were 4.4% while men were 3.1% positive (P=0.136). The data confirmed that there are many asymptomatic patients of CE in Tashkent. It is indicated that CE is an endemic disease of public health importance in Uzbekistan.

The book reviews the concept of least cost planning which can be applied in all stages of energy management. It is a system-analytical concept of planning, cost optimisation, and application of investment alternatives in energy supply and energy conversion. In particular, the authors discuss inhowfar the positive results achieved in the USA with cost saving programmes based on least-cost planning can be applied to the situation of the Federal Republic of Germany. It is shown that least-cost planning could make a key contribution to operations scheduling of public utilities, in the establishment and implementation of local and regional energy concepts, and especially in the theory and practice of state supervision of the energy sector. The 14 contributions can be found as separate records in this database. (orig./HP) With 31 figs [de

2015-01-01

The implementation of the energy transition and the developments in the national and international Energy markets constantly require sound analysis and new answers. The symposium ''optimization in the energy sector'' gives an overview of methods and models that can be practically used for decision support. Storage and electromobility as demand flexibility are important factors for the long-term design of the German and European energy system. But methodological aspects such as the consideration of uncertainties at the conference an important place is given. A key issue is also the short and medium term further development of the electricity market design. Not only broadly but also in detail e.g. the standard benefit and intraday markets there is considerable potential for optimization, which will be discussed in the context of technical presentations. And in view of challenging market environment is also new approaches to portfolio management a great importance for the practice. Therefore we are convinced that the Conference and its results for energy companies, public services and new entrants in the energy industry as well are of interest as for consultants, authorities, associations and energy economic research institutes.

Ediger, Volkan S.; Camdali, Unal

2007-01-01

This study aims at examining energy and exergy efficiencies in Turkish transportation sector. Unlike the previous studies, historical data is used to investigate the development of efficiencies of 17 years period from 1988 to 2004. The energy consumption values in tons-of-oil equivalent for eight transport modes of four transportation subsectors of the Turkish transportation sector, including hard coal, lignite, oil, and electricity for railways, oil for seaways and airways, and oil and natural gas for highways, are used. The weighted mean energy and exergy efficiencies are calculated for each mode of transport by multiplying weighting factors with efficiency values of that mode. They are then summed up to calculate the weighted mean overall efficiencies for a particular year. Although the energy and exergy efficiencies in Turkish transport sector are slightly improved from 1988 to 2004, the historical pattern is cyclic. The energy efficieny is found to range from 22.16% (2002) to 22.62% (1998 and 2004) with a mean of 22.42±0.14% and exergy efficiency to range from 22.39% (2002) to 22.85% (1998 and 2004) with a mean of 22.65±0.15%. Overall energy and exergy efficiencies of the transport sector consist mostly of energy and exergy efficiencies of the highways subsector in percentages varying from 81.5% in 2004 to 91.7% in 2002. The rest of them are consisted of other subsectors such as railways, seaways, and airways. The overall efficiency patterns are basically controlled by the fuel consumption in airways in spite of this subsector's consisting only a small fraction of total. The major reasons for this are that airways efficiencies and the rate of change in fuel consumption in airways are greater than those of the others. This study shows that airway transportation should be increased to improve the energy and exergy efficiencies of the Turkish transport sectors. However, it should also be noted that no innovations and other advances in transport technologies are

This paper analyzes the changes in the energy consumption of the service sector in France over the period 1995-2006, using the logarithmic mean Divisia index I (LMDI I) decomposition method. The analysis is carried out at various disaggregation levels to highlight the specifics of each sub-sector and end-use according to their respective determinants. The results show that in this period the economic growth of the service sector was the main factor that led to the increase in total energy consumption. Structure, productivity, substitution and intensity effects restricted this growth, but with limited effect. By analyzing each end-use, this paper enables a more precise understanding of the impact of these factors. The activity effect was the main determinant of the increase in energy consumption for all end-uses except for air conditioning, for which the equipment rate effect was the main factor. Structural changes in the service sector primarily impacted energy consumption for space heating and cooking. Improvements in productivity limited the growth of energy consumption for all end-uses except for cooking. Finally, energy efficiency improvements mainly affected space-heating energy use.

In light of Germany's energy system transformation, this paper examines differences in employment structures and wage differentials between renewable energy establishments and their sector peers. To do so, we have developed a novel data set by linking company-level information from the German Renewable Energy Federation with administrative establishment-level data from the Institute for Employment Research. Descriptive evidence shows significant differences in wages and several other characteristics between renewable energy establishments and their sector peers. Our estimates give evidence that human capital and other establishment-level characteristics mostly explain the wage differential among manufacturers and energy providers. However, we find a persistent ‘renewable energy wage premium' of more than ten percent in construction/installation activities and architectural/engineering services. We interpret this premium as a positive indirect effect of the promotion of renewable energies for the benefit of employees in renewable energy establishments within these two sectors. - Highlights: • Renewable energy (RE) firms pay considerably more than their non-RE sector peers. • In manufacturing and energy supply, firm attributes explain mainly the wage gap. • In installation, planning and project management one third remains unexplained. • This unexplained rest represents a ‘RE wage premium’ of around 10 percent. • The employees in both sectors are the ‘hidden winners’ of RE promotion.

The energy sector is the biggest contributor of anthropogenic emissions of greenhouse gases into the atmosphere in Iran. However, abundant potential for implementing low-carbon technologies offers considerable emissions mitigation potential in this sector, and technology transfer is expected to play an important role in the widespread roll-out of these technologies. In the current work, globally existing low-carbon energy technologies that are compatible with the energy sector of Iran are identified and then prioritised against different criteria (i.e. Multi Criteria Decision Analysis). Results of technology prioritisation and a comprehensive literature review were then applied to conduct a SWOT analysis and develop a policy package aiming at facilitating the transfer of low carbon technologies to the country. Results of technology prioritisation suggest that the transport, oil and gas and electricity sectors are the highest priority sectors from technological needs perspective. In the policy package, while fuel price reform and environmental regulations are categorised as high priority policies, information campaigns and development of human resources are considered to have moderate effects on the process of technology transfer. - Highlights: • We examined the process of technology transfer in the energy sector of Iran. • Multi Criteria Decision Analysis techniques are used to prioritise the technological needs of the country. • Transportation, electricity and oil and gas sectors are found as recipients of new technologies. • A policy package was designed for facilitating technology transfer in the energy sector

Energy utilization and greenhouse-gas emissions: Transportation sector, topical report

International Nuclear Information System (INIS)

Darrow, K.G.

1992-06-01

The objective of the report is to compare the emissions of greenhouse gases for alternative end-use technologies in the transportation sector. Scientists assert that global warming is occurring and will continue to occur as a result of increasing concentrations of certain gases in the atmosphere. Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are the focus of this analysis because they are believed to cause three-fourths of the global warming effect and because energy production and use are a significant source of these emissions. Greenhouse gas emissions in the energy sector occur during energy production, conversion, transportation and end-use. This analysis compares alternative transportation sector fuel/technology choices in terms of their total fuel-cycle emissions of greenhouse gases. The emphasis of this report is on the end use comparison. The fuel-cycle emissions comparison was developed in a companion report

Full Text Available Development of the concepts of sustainable development and corporate social responsibility has a great impact on reporting in companies. The increase of their importance has resulted in a need to create a reporting system that would provide information on not only the methods but also the results of implementation of those concepts in companies. Globally, there are many organizations that promote and support companies in the area of integrated reporting. The most popular standard for reporting non-financial data that is used by a number of companies worldwide is the Global Reporting Initiative (GRI Guidelines. The main objective of the GRI is to support the development of sustainable economy in which companies take responsibility for the economic, social, and environmental consequences of their operations, manage that responsibility, and report all their actions. An example of a sector where the concept of sustainable development and its transparent reporting has an impact on the formation of values is the energy sector, which creates value for stakeholders and, together with the financial sector, has the greatest impact on national economies.

Central Asia: A major emerging energy player in the 21st century

Energy is the most abundant and valuable natural resource of Central Asia and northwest China and includes oil, gas, coal, electricity, and renewables. Kazakhstan has large reserves of oil and coal. Turkmenistan and Uzbekistan have significant reserves of gas. Kyrgyzstan produces significant amounts of hydroelectric power. Xinjiang, China has significant coal resources and an uncertain, although generally promising, potential for oil in the Tarim basin. These energy reserves form the basis for future economic growth and development in the region, and energy exports are beginning to generate important foreign exchange revenues. Although Central Asia enjoys vast energy development potential, there are obstacles to exploiting these resources, including limited infrastructure for transporting energy-notably oil and gas pipelines and electric transmission lines-in the region, political turmoil, payment difficulties, and inadequate energy policies. Despite these challenges, however, with appropriate government planning Central Asia is poised to become a significant world supplier of energy, especially in the oil and gas sectors, and the region is likely to diminish OPEC's influence of the global oil market over the long term.

Highlights: • We analyzed the factors impacting China’s emissions from a sectoral perspective. • Sector-specific policies and measures for emissions mitigation were evaluated. • Economic growth dominantly increased the emissions in the economic sectors. • Energy intensity decrease primarily reduced the emissions in the economic sectors. • Residential emissions growth was mainly driven by increase in per-capita energy use. - Abstract: In order to better understand sectoral greenhouse gas (GHG) emissions in China, this study utilized a logarithmic mean Divisia index (LMDI) decomposition analysis to study emission changes from a sectoral perspective. Based on the decomposition results, recently implemented policies and measures for emissions mitigation in China were evaluated. The results show that for the economic sectors, economic growth was the dominant factor in increasing emissions from 1996 to 2011, whereas the decline in energy intensity was primarily responsible for the emission decrease. As a result of the expansion of industrial development, economic structure change also contributed to growth in emissions. For the residential sector, increased emissions were primarily driven by an increase in per-capita energy use, which is partially confirmed by population migration. For all sectors, the shift in energy mix and variation in emission coefficient only contributed marginally to the emissions changes. The decomposition results imply that energy efficiency policy in China has been successful during the past decade, i.e., Top 1000 Priorities, Ten-Key Projects programs, the establishment of fuel consumption limits and vehicle emission standards, and encouragement of efficient appliances. Moreover, the results also indicate that readjusting economic structure and promoting clean and renewable energy is urgently required in order to further mitigate emissions in China

Inappropriate use of antibiotics has resulted in a dramatic increase of antimicrobial resistance in developing countries. We examined knowledge, attitudes, and practices of antibiotic use in three Asian countries. A nationwide cross-sectional study of teachers in large cities of Yemen, Saudi Arabia, and Uzbekistan was conducted. A random sample of 1,200 teachers was selected in each country. Data were collected through a questionnaire-based survey and then analyzed using descriptive and multivariate statistical methods. The prevalence of non-prescription antibiotic use ranged from 48% in Saudi Arabia to 78% in Yemen and Uzbekistan. Pharmacies were the main source of non-prescribed antibiotics. The most common reasons for antibiotic use were cough (40%) and influenza (34%). Forty-nine percent of respondents discontinued antibiotics when they felt better. Although awareness of the dangers of antibiotic use correlated inversely with self-medication, understanding of the appropriate use of antibiotics was limited. The prevalence of antibiotic self-medication in the educated adult population in the studied countries was found to be alarmingly high. Effective strategies involving regulatory enforcement prohibiting sales of antibiotics without prescription should be implemented along with educational interventions for health professionals and the public.

Strategies for implementation of CO2-mitigation options in Nigeria's energy sector

Ibitoye, F.I.; Akinbami, J.-F.K.

1999-01-01

Recent studies indicate that Nigeria's CO 2 budget was about 164 million tonnes (MTons) in 1990, of which the energy sector contributed close to 55%. It is expected that CO 2 emissions emanating from the energy sector will increase from 90 MTons in 1990 to about 3 times this value in another 30 years, assuming a least-cost moderate development scenario. A number of viable CO 2 -mitigation options have already been identified in the energy sector, some of them the so-called 'win-win' options. As attractive as some of these options might appear, their implementation will depend on the removal of certain barriers. These barriers include a lack of legislative framework, a lack of awareness, a lack of access to appropriate technology, as well as inappropriate energy-pricing policies, among others. The paper presents an overview of Nigeria's energy-sector, the CO 2 mitigation-options, the factors militating against implementation of the options, and some policy recommendations for removal of the barriers.

Highlights: • The overall energy and exergy efficiencies of the sector were calculated. • The overall efficiencies were compared to other countries. • The overall energy and exergy efficiencies have been predicted by scenario approach. • A summary of recommendations to improve the sector is provided. - Abstract: Transportation is the second largest energy consumer sector in Iran which accounts for 24% of total energy consumption in 2009. This large percentage (almost a quarter) of energy consumption necessitates the determination of energy and exergy flows and their respective losses, which will enable the reduction of both energy growth and its consequent environmental impacts in the near future. This paper attempts to analyze and investigate the energy and exergy utilization of the transportation sector in Iran for the period of 1998–2009. Additionally, the total energy consumption in each subsector and the overall energy and exergy efficiencies are predicted via scenario approach. A comparison of the overall energy and exergy efficiencies of Iran with six other countries is also presented. The results show that the overall energy and exergy efficiencies of transportation sector in Iran is higher than China and Norway, while it is lower than Saudi Arabia, Jordan, Turkey, and Malaysia for the year 2000. Road appears to be the most efficient subsector. The overall energy efficiency is determined to be in the range of 22.02% in 1998, to 21.49% in 2009, while the overall exergy efficiency is determine to be in the range of 21.47% in 1998, to 21.19% in 2009. The energy consumption in each subsector is predicted from 2010 to 2035. It was discovered that the overall energy and exergy efficiencies possesses an upward trend during this time period. Finally, some recommendations vis-à-vis the improvement of the energy and exergy efficiencies in Iranian transportation sector in the future was provided and duly discussed

The decarbonisation of energy systems is one of the important issues of the present energy policies. One of the ways of achieving this is to focus on local energy systems, thus ensuring as much as possible their heat and power self-sufficiency by applying local renewable resource integration and transformation of the renewable energy. Increasing the share of renewables within the local energy balance could be accomplished by using a variety of approaches. One possibility is combining the Locally Integrated Energy Sectors' concept with the novel management and organisation of a renewables-based network. As a first priority, the proposed comprehensive approach focuses on increasing the energy efficiency of municipal heat and power systems using the Locally Integrated Energy Sectors' concept, which is followed by the integration of renewable energy sources with the establishment of a renewable-based network. The proposed approach is illustrated by a case study of district heating based on wood biomass for the municipality Ormož, Slovenia by integrating various end-users from different sectors. - Highlights: • The paper presents a new approach for accelerated inception of RES in municipalities. • LIES with RES network increases energy efficiency and accelerates RES integration. • A demonstration case of district heating on wood biomass within Ormož was performed.

Filippini, Massimo; Hunt, Lester C.; Zorić, Jelena

2014-01-01

The promotion of energy efficiency is seen as one of the top priorities of EU energy policy (EC, 2010). In order to design and implement effective energy policy instruments, it is necessary to have information on energy demand price and income elasticities in addition to sound indicators of energy efficiency. This research combines the approaches taken in energy demand modelling and frontier analysis in order to econometrically estimate the level of energy efficiency for the residential sector in the EU-27 member states for the period 1996 to 2009. The estimates for the energy efficiency confirm that the EU residential sector indeed holds a relatively high potential for energy savings from reduced inefficiency. Therefore, despite the common objective to decrease ‘wasteful’ energy consumption, considerable variation in energy efficiency between the EU member states is established. Furthermore, an attempt is made to evaluate the impact of energy-efficiency measures undertaken in the EU residential sector by introducing an additional set of variables into the model and the results suggest that financial incentives and energy performance standards play an important role in promoting energy efficiency improvements, whereas informative measures do not have a significant impact. - Highlights: • The level of energy efficiency of the EU residential sector is estimated. • Considerable potential for energy savings from reduced inefficiency is established. • The impact of introduced energy-efficiency policy measures is also evaluated. • Financial incentives are found to promote energy efficiency improvements. • Energy performance standards also play an important role

Iraq's energy sector was rehabilitated from 2003 to 2005. The focus of rehabilitation was on restoring Iraq's electricity and oil infrastructure to pre-war production levels; delivering electricity and refined fuels for domestic consumption; and delivering electricity and oil security. This paper provided an analysis of the impact of Coalition efforts and insurgent activities on energy sector performance using time-series models. The paper presented a simple three-equation model consisting of an insurgent attack equation, an investment equation, and production function. The paper also discussed the phases of the insurgency in Iraq, with particular reference to the beginning of the insurgency; initial bombing campaign; escalation of the insurgency; and intra-Iraqi conflict. Key energy sector indicators and regression results were also presented for oil production; diesel production; gasoline production; oil exports; and production and consumption of electricity. It was concluded that expenditures by the United States on oil infrastructure appear to have been relatively efficiently spent. 16 refs., 9 tabs

Energy in the market services sector in 2011: uses differentiated according to activity

Martin, Jean-Philippe

2015-04-01

In 2011, average energy consumption in the market services sector (excluding transport) was 266 kWh/ m 2 . This is greater than the consumption for residential buildings, which reached 186 kWh/m2. Indeed, activities in certain service-sector establishments sometimes require specific uses that do not exist in the residential sector or are more intensive, such as cooking, intensive computing, laundering or refrigeration. Businesses employing at least one person could be divided into five groups depending on their energy mix and energy uses. (author)

Competition within the energy sector and State regulation

Larsen, A.; Jess Olsen, O.

It is presumed that energy markets will be liberalized. Questions discussed are how the Danish electricity and gas sectors are to be re-regulated in order to ensure that this goal is reached in the most satisfactory manner (cheaper energy supply under competitive conditions) and whether there will be a conflict between the goal of liberalization and the environmental goals of clean technology and energy conservation. It is suggested that a compulsory splitting up of the two regional power associations in Denmark should not be necessary. Transmission and distribution must continue to be regulated as these are natural monopolies not compatible with competition. District heating will still be a monopoly and its prices must be closely regulated to prevent soaring. The opening up of the European gas market to competition will threaten Danish energy utilities. The increasing compulsory use of natural gas in cogeneration plants to politically determined high prices is not sustainable under competitive conditions. Energy saving activities should not be affected. Energy surcharges are attractive measures on a liberalized market. The regulation of competition ought to be incorporated explicitly as a restriction in the Ministry of Energy's energy policy regulation. Energy utilities could be excluded from participation in price setting. International regulation of competition will demand a clarification of the separation of regulatory competence between the member states and the European Commission. It will also be necessary to adjust the Danish regulation of the electricity sector to the future Scandinavian system. (AB) 77 refs

China's economic reform and industry sector energy requirement: A forecast to 2015

Gu, A.Y.

1997-01-01

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

LMDI Decomposition Analysis of Energy Consumption in the Korean Manufacturing Sector

Suyi Kim

2017-02-01

Full Text Available The energy consumption of Korea’s manufacturing sector has sharply increased over the past 20 years. This paper decomposes the factors influencing energy consumption in this sector using the logarithmic mean Divisia index (LMDI method and analyzes the specific characteristics of energy consumption from 1991 to 2011. The analysis reveals that the activity effect played a major role in increasing energy consumption. While the structure and intensity effects contributed to the reduction in energy consumption, the structure effect was greater than the intensity effect. Over the periods, the effects moved in opposite directions; that is, the structure effect decreased when the intensity effect increased and vice versa. The energy consumption by each industry is decomposed into two factors, activity and intensity effects. The increase of energy consumption due to the activity effect is largest in the petroleum and chemical industry, followed by the primary metal and non-ferrous industry, and the fabricated metal industry. The decrease of energy consumption due to the intensity effect is largest in the fabricated metal industry, followed by the primary metal and non-ferrous industry, and the non-metallic industry. The energy consumption due to intensity effect in the petroleum and chemical industry has risen. To save energy consumption more efficiently for addressing climate change in this sector, industrial restructuring and industry-specific energy saving policies should be introduced.

Energy use efficiency in the Indian manufacturing sector: An interstate analysis

International Nuclear Information System (INIS)

Mukherjee, Kankana

2008-01-01

This paper approaches the measurement of energy efficiency from a production theoretic framework and uses Data Envelopment Analysis to measure energy efficiency in the Indian manufacturing sector. Using data from the Annual Survey of Industries for the years 1998-99 through 2003-04, the study compares the energy efficiency in manufacturing across states, based on several models. The results show considerable variation in energy efficiency across states. Comparing the results across our models, we find that the relative pricing of energy does not provide the appropriate incentives for energy conservation. A second-stage regression analysis reveals that states with a larger share of manufacturing output in energy-intensive industries have lower energy efficiency. Also, higher quality labor force associates with higher energy efficiency. Finally, the power sector reforms have not yet had any significant impact on achieving energy efficiency

Unfair and excessive prices in the energy sector

International Nuclear Information System (INIS)

Van der Woude, M.

2008-01-01

The concept of competition refers to a process where firms dispute the favour of their customers by proposing better products at the lowest possible price. This consumer welfare creating process is to a large extent Darwinian in nature: those who cannot compete must die. The law of supply and demand is ruthless and so is competition law. Principles of fairness and justice are extraneous to competition law: the lion eats the deer. Still, EC competition law is not amoral, as illustrated by the very first example of abusive conduct given by Article 82 EC: 'directly or indirectly imposing unfair purchase or selling prices or other unfair trading conditions' can constitute an abuse. The concept of fairness as a constituent element of EC competition law may disturb those who analyze the competitive process through a scientific lens. Fairness does not relate to economic effects and cannot be measured or quantified. It is a concept that appeals to ethics and norms. The dichotomy between competition as an amoral welfare creating process, that can be the subject of economic research, and the normative concept of fairness does not necessarily lead to a contradiction. Fairness becomes relevant where the competitive process has ceased to play its welfare creating role: i.e. where monopolies prevail over perfect competition. When confronted to a monopoly, abstention is the customer's only choice and for some goods, such as food, clothing and housing, abstention is not considered as a realistic choice. In scenarios where the monopolist faces an inelastic demand curve, fairness is probably the customer's only safety buoy. The energy sector is one of the sectors where these situations occur. In our modern societies, customers expect the light to go on, when they turn the switch, and their houses to be heated, when activating their boilers. Candles and jumpers not offering realistic alternatives, demand is close to inelastic, at least on the short term. Moreover, the energy sector

Energy efficiency in the transport sector in the EU-27: A dynamic dematerialization analysis

Energy use in the European Union's (EU) transport sector amounted to 340 Mtoe in 1999 with the following increasing trend up to 379 Mtoe in 2007 and a decrease from 2008 on, down to 365 Mtoe in 2010. This changing pattern posed several fundamental questions and uncertainties regarding the broader picture of energy efficiency and environmental protection. One of them refers to absolute changes in energy use efficiency in the transport sector over time and the ways of measuring efficiency. Traditional scientific approaches conceptualized to measure efficiency of energy use do not address annual dynamics of changes in the energy use in a given sector per capita. Thus, they are not precise enough for political and methodological purposes as they do not reflect the exact amount of energy consumed in the respective countries and societies. This paper shows a possible solution to this problem and a new perspective on measuring energy efficiency by using the product generational dematerialization (PGD) indicator. The PGD indicator allows for measuring energy efficiency as a dynamic change of consumption and population occurring simultaneously. Thus, it provides an extension to the traditional methodology commonly used for measuring efficiency. To visualize a practical application of this approach, the paper provides an example of evaluating energy efficiency in the transport sector in the EU-27 in 2000–2010. The results of the analysis show a clear materialization tendency in the transport sector (the energy consumption change exceeded the population growth) until 2007 and a reverse tendency (dematerialization) between 2008 and 2010. As energy consumption has a direct impact on environmental quality and exhaustion of natural resources, the paper points out the necessity of extending sustainable resource management policies by new methodologies and providing more efficient solutions for energy consumption in the transport sector. - Highlights: • PGD indicator proves a

Energy wealth and tax reform in Russia and Kazakhstan

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

Energy sector reform in India : a review

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

Full Text Available Today, the topic of corporate governance has become vital for the most researches and scientific controversies. The corporate governance is now playing a key role in economic and social development of a country, and it has began to significantly matter for both industrialized and most of the developing countries. In the meantime, little is known for the world community about the state and problems of corporate governance in Uzbekistan. In this regard, in this paper we mainly address the present situation in Uzbek corporate governance as well as, as a special focus, make comparison of the Uzbek and German board’s supervisory role practices. This paper may be interesting for those who are not aware of the corporate governance in Uzbekistan and who would like to more or less know about it.

Coleman, J.

1993-01-01

The European Bank for Reconstruction and Development was established in 1991 to assist central and eastern European countries in making the transition from command economies to market economies. The Bank provides loans, equity investments, guarantees, advice, and technical cooperation to qualified applicants through its merchant banking and development banking operations. In the energy sector, the Bank recognizes that the energy resources of eastern Europe are enormous but so are the problems associated with their development. Since its foundation, most of the Bank's energy-related lending has been in the oil and gas sector in Russia and the Baltic countries. The Bank has approved eight projects in that sector with total capital costs of ca US$1.7 billion. Major problem areas to be overcome include uneconomic domestic pricing, high energy intensity and pollution, inadequate legal frameworks, inappropriate tax structures, and institutional complexity. Canadian firms have been actively involed in Bank-financed projects in the Russian oil and gas sector, and two such projects are briefly described. They comprise joint ventures with Russian enterprises or associations and include rehabilitation of Siberian oil fields and drilling new wells in the Komi (Arctic) region. A common feature of these projects is that they were well under way before the Bank got involved, but the Bank brings the benefits of additional financing and providing moral support and expertise which can be useful in overcoming administrative and regulatory difficulties

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

Faudon, Valerie; Jouette, Isabelle; Le Ngoc, Boris

2015-01-01

This publication states the opinion of the SFEN (the French Society of Nuclear Energy) about the project proposed by the French Ministry of Ecology for the creation of a label named 'Energy transition and climate' for the financial sector. Such a label aims at mobilising a part of savings for the benefit of energy and ecology transition, and at bringing the French ecological expertise at the European level. In this document, the SFEN expresses its surprise that labels will not be awarded to activities related to the nuclear sector whereas, as it is herein commented and outlined, nuclear energy is a low-carbon energy, and meets environmental and social requirements associated with the label (preservation of air quality, optimisation of the water resource by nuclear plants, strict regulation and controls of releases made by nuclear installations, management of the uranium resource, measures of protection of biodiversity about nuclear sites, exemplary governance and dialogue on environmental and social issues with the public)

Alcantara, Vicent; Padilla, Emilio

2003-01-01

In this paper we analyze the determination of 'key' sectors in the final energy consumption. We approach this issue from an input-output perspective and we design a methodology based on the elasticities of the demands of final energy consumption. As an exercise, we apply the proposed methodology to the Spanish economy. The analysis allows us to indicate the greater or lesser relevance of the different sectors in the consumption of final energy, pointing out which sectors deserve greater attention in the Spanish case and showing the implications for energy policy

Full text: Countering illicit trafficking of nuclear weapon and its components is an important task in the modern world. For this reason, at the borders and customs points the control of transportation is to be conducted in order to determine radioactive and fissile materials in them. This report presents the results of works performed in the period of 2001 - 2005 years on the program for development of radiation monitors and equipping the Uzbekistan border customs points with them, in order to fight the smuggling of nuclear and radioactive materials. The Republic of Uzbekistan is located on the transit transportation crossroad, Kazakhstan, Kyrgyzstan, Russia and Western Europe - to the North, and Iran, Turkmenistan, Afghanistan and others - to the South. Therefore, this program is important for saving peace in the world and fighting any attempts to create nuclear weapon in the region. The radiation monitoring equipment is installed at the border customs points through which the transportation enters the Uzbekistan and at the Tashkent International Airport where passengers arrive by air. Also, the customs points are equipped through which the transportation quits for South and international passenger depart. The radiation portal monitors are designed by CIS Aspect (Dubna, Moscow region), however, we develop our own portal monitoring system which can be produced after certification. The Institute of Nuclear Physics provides the technical expertise that includes installation, calibration, maintenance, and secondary alarm response; mobile response units are being developed to rapidly and accurately identify seized material and recommend handling procedures. At present we are accumulating information on the alarm from the Yantar - type radiation monitor at the customs check-points and examining characteristics of the system to improve the results of our research

Engineering in the energy sector. The single market and the engineering sector

Projects with large infrastructures, particularly those in the field of energy, provide a strong boost to certain industrial sectors in the country. In the case of Spain, the policy of direct management 'by components' of these projects - hydroelectric power plants, petrochemical plants, thermoelectric plants and nuclear power plants - adopted by the electric utility owners has furthered not only the local equipment manufacturing industry but also the engineering sector. At present, with full implementation of the Single Market in sight, it is particularly interesting for Spain to continue building up a powerful engineering sector, increasing its size and usefulness, and extending its traditional areas of action to other technologies, more on the lines of engineering and consulting firms in the USA than in the rest of Europe. The intention is to endow our equipment and construction companies with the skills necessary to enable them to compete with large European conglomerates in their respective sectors. The structure of these conglomerates usually contains engineering capabilities which are not habitual in our industry. Examples are given, showing how this model has been used to compete and win awards for important international projects. A specific analysis has been made of the position of Spanish engineering and industry in nuclear power generation projects in the former Soviet Union and East European countries, in which large investments are expected to be made.

This paper analyses the distribution of benefits between firms and consumers due to the price regulation of the Spanish energy sectors (electricity, oil fuels and gas) during the decade 1987-1997. To that effect, we compare the actual evolution of energy prices with alternate benchmarks in order to assess the potential existence of a pro-industry or a pro-consumer bias in the pricing policies followed by the regulator. Our results show a pro-industry-biased regulatory context, where consumers benefited very little from price control. The successive price adjustments over time allowed the companies to keep all the productivity gains and cost reductions and to increase their profitability rates relative to those achieved in the manufacturing sector.

An analysis of Grenada's power sector and energy resources: a role for renewable energy technologies?

International Nuclear Information System (INIS)

Wiesser, D.

2004-01-01

Presently, Grenada's power sector is fully dependent on fossil fuel imports for meeting the country's electricity demand. Electric utilities in Small Island Developing States (SIDS), in general, face high cost of electricity generation due to diseconomies of scale in production, consumption and logistical aspects. Grenada's private power monopoly is no exception and the high cost of import dependent electricity generation places an increasing burden on economic development. In light of rapid technological and economic improvement of renewable energy technologies (RETs), the country's abundant sources of renewable energy should be harnessed. Benefits are envisaged to include lower electricity cost, better environmental performance and a safer and diversified supply of energy. However, barriers for shifting power production towards meaningful contributions from RETs exist, both in government and industry. This work analyses important economic interactions between the power sector and economic development, bringing to attention the importance of power sector reform. Further, present problems of integrating RETs into the grid, ranging from technical and regulatory issues to shareholder interest are investigated. A summary and analysis of past research into renewable sources of energy (RES) underscore the potential for power production from RETs in Grenada. (author)

Sector-based political analysis of energy transition: Green shift in the forest policy regime in France

International Nuclear Information System (INIS)

Sergent, Arnaud

2014-01-01

This article examines energy transition political process from a sector-based approach, through the analysis of recent shift in the French forest policy regime. We demonstrate that, since 2007, energy transition policies have led to a harvesting turn within the French forest policy framework, meaning that priority is given to wood mobilisation, mainly for biomass uses. In addition, our findings suggest that the political authority wielded by the state over forest policy has shifted from forest administrative services to energy agencies and local authorities. Finally, we show that, although implementation of the harvesting turn is a cause of sectoral and inter-sectoral tensions, energy transition challenge also contributes to a process of (re)institutionalisation of mediation relationships among forestry stakeholders and wood-based industries representatives. The article concludes by arguing that sectors should retain relevant institutional frameworks for actors when choosing political arrangements required for implementing energy transition policy. - Highlights: • Implementing energy transition policy potentially challenges sector-based politics. • We propose a policy regime framework and socio-political investigations. • We analyse the political impact of energy transition policy on French forest sector. • Shifts occur in sectoral policy framework, authority, and mediation relationships

2010-01-01

British Columbia (BC) possesses significant wind energy resources, and many wind energy projects are currently in the planning phase or are already under construction. Wind power policies in the province have been designed to ensure the secure and orderly development of the wind power industry. Policies in the province include a 10-year exemption from participation rents for new projects as well as a policy that has established the maximum permissible noise levels for wind farms located near residential properties. BC's wind power development plan forms part of the province's aim to become electricity self-sufficient by 2016 while ensuring that clean or renewable energy generation accounts for at least 90 per cent of total generation. This guide provided an outline of the province's wind energy sector, and provided a listing of selected wind power operators. Details of new wind power projects were also presented. 11 fig.

Highlights: ► We evaluate energy efficiency under framework of total factor energy efficiency. ► We focus on industry sector of China. ► We use statistical data of industrial enterprises above designated size. ► Energy efficiencies among regions in China are obvious because of technological differences. ► Large scale of investment should be stopped especially in central and western regions. -- Abstract: The rapid growth of the Chinese economy has resulted in great pressure on energy consumption, especially the energy intensive sector – the industrial sector. To achieve sustainable development, China has to consider how to promote energy efficiency to meet the demand of Chinese rapid economic growth, as the energy efficiency of China is relatively low. Meanwhile, the appeal of energy saving and emission reduction has been made by the Chinese central government. Therefore, it is important to evaluate the energy efficiency of industrial sector in China and to assess efficiency development probabilities. The framework of total factor energy efficiency index is adopted to determine the discrepancy of energy efficiency in Chinese industrial sector based on the provincial statistical data of industrial enterprises above designated size in 30 provinces from 2005 to 2009, with gross industrial output as the output value and energy consumption, average remaining balance of capital assets and average amount of working force as the input values. Besides, in considerate of the regional divide of China, namely eastern, central, and western, and economic development differences in each region, energy efficiency of each region is also analysed in this paper. The results show that there is room for China to improve its energy efficiency, especially western provinces which have large amount of energy input excess. Generally speaking, insufficient technological investment and fail of reaching best scale of manufacture are two factors preventing China from energy

Energy sector during 1993 and 1994

The author emphasises the most important problem facing Bulgarian energy sector during the transition period to market economy - pricing reform. He discusses the way of forming the price based on 'long-term marginal expenditures' (LTME) for delivering the services. LTME include 'short-term marginal expenditures'(STME), (operational expenditures, energy cost) and additional investments for modernization of existing units. The first step of the pricing reform should be an increase of the prices at least up to the level of STME. Eventually the pricing reform must change the tariff structure responsible for stimulation of energy savings and market principles adapted for domestic realities. An attempt to connect the monopolist economic theory at market conditions with particular price corrections proposed by the Committee of Energetics for 1994 is made. 9 figs. (author)

The energy rebound effects across China’s industrial sectors: An output distance function approach

Li, Ke; Zhang, Ning; Liu, Yanchu

2016-01-01

Highlights: • Output distance function for the energy rebound effect is developed. • The aggregate energy rebound effect of China is 88.42%. • Investment-driven economic growth is not conducive to energy-saving. - Abstract: Improving energy efficiency sustainability is a target of the Chinese government. However, the effectiveness of energy conservation policy is affected by the energy rebound effect under which energy efficiency improvement reduces the effective price of energy services, thereby completely or partially offsetting the energy saved by efficiency improvement. Based on the output distance function, this paper develops an improved estimation model of the energy rebound effect, which is logically consistent with the quantities of energy savings and energy rebounds induced by technological progress. Results show that the aggregate energy rebound effect of 36 industrial sectors in China over 1998–2011 is 88.42%, which implies that most of the expected energy savings are mitigated. Investment-driven economic growth is not conducive to energy-saving and results in a strong energy rebound effect in the following year. The equipment and high-end manufacturing sectors have low levels of rebound effect, indicating that increasing the proportion of such firms in the total manufacturing sector can improve the performance of energy conservation. The high level and heterogeneity in rebound effects strongly suggest that varies strategies are necessary for energy conservation among China’s industrial sectors.

The energy efficiency services sector (EESS) is poised to become an increasingly important part of the U.S. economy. Climate change and energy supply concerns, volatile and increasing energy prices, and a desire for greater energy independence have led many state and national leaders to support an increasingly prominent role for energy efficiency in U.S. energy policy. The national economic recession has also helped to boost the visibility of energy efficiency, as part of a strategy to support economic recovery. We expect investment in energy efficiency to increase dramatically both in the near-term and through 2020 and beyond. This increase will come both from public support, such as the American Recovery and Reinvestment Act (ARRA) and significant increases in utility ratepayer funds directed toward efficiency, and also from increased private spending due to codes and standards, increasing energy prices, and voluntary standards for industry. Given the growing attention on energy efficiency, there is a concern among policy makers, program administrators, and others that there is an insufficiently trained workforce in place to meet the energy efficiency goals being put in place by local, state, and federal policy. To understand the likelihood of a potential workforce gap and appropriate response strategies, one needs to understand the size, composition, and potential for growth of the EESS. We use a bottom-up approach based upon almost 300 interviews with program administrators, education and training providers, and a variety of EESS employers and trade associations; communications with over 50 sector experts; as well as an extensive literature review. We attempt to provide insight into key aspects of the EESS by describing the current job composition, the current workforce size, our projections for sector growth through 2020, and key issues that may limit this growth.

Carbon tax scenarios and their effects on the Irish energy sector

International Nuclear Information System (INIS)

Di Cosmo, Valeria; Hyland, Marie

2013-01-01

In this paper we use annual time series data from 1960 to 2008 to estimate the long run price and income elasticities underlying energy demand in Ireland. The Irish economy is divided into five sectors: residential, industrial, commercial, agricultural and transport, and separate energy demand equations are estimated for all sectors. Energy demand is broken down by fuel type, and price and income elasticities are estimated for the primary fuels in the Irish fuel mix. Using the estimated price and income elasticities we forecast Irish sectoral energy demand out to 2025. The share of electricity in the Irish fuel mix is predicted to grow over time, as the share of carbon intensive fuels such as coal, oil and peat, falls. The share of electricity in total energy demand grows most in the industrial and commercial sectors, while oil remains an important fuel in the residential and transport sectors. Having estimated the baseline forecasts, two different carbon tax scenarios are imposed and the impact of these scenarios on energy demand, carbon dioxide emissions, and government revenue is assessed. If it is assumed that the level of the carbon tax will track the futures price of carbon under the EU-ETS, the carbon tax will rise from €21.50 per tonne CO 2 in 2012 (the first year forecasted) to €41 in 2025. Results show that under this scenario total emissions would be reduced by approximately 861,000 tonnes of CO 2 in 2025 relative to a zero carbon tax scenario, and that such a tax would generate €1.1 billion in revenue in the same year. We also examine a high tax scenario under which emissions reductions and revenue generated will be greater. Finally, in order to assess the macroeconomic effects of a carbon tax, the carbon tax scenarios were run in HERMES, the ESRI's medium-term macroeconomic model. The results from HERMES show that, a carbon tax of €41 per tonne CO 2 would lead to a 0.21% contraction in GDP, and a 0.08% reduction in employment. A higher carbon

Unfair and excessive prices in the energy sector

The concept of competition refers to a process where firms dispute the favour of their customers by proposing better products at the lowest possible price. This consumer welfare creating process is to a large extent Darwinian in nature: those who cannot compete must die. The law of supply and demand is ruthless and so is competition law. Principles of fairness and justice are extraneous to competition law: the lion eats the deer. Still, EC competition law is not amoral, as illustrated by the very first example of abusive conduct given by Article 82 EC: 'directly or indirectly imposing unfair purchase or selling prices or other unfair trading conditions' can constitute an abuse. The concept of fairness as a constituent element of EC competition law may disturb those who analyze the competitive process through a scientific lens. Fairness does not relate to economic effects and cannot be measured or quantified. It is a concept that appeals to ethics and norms. The dichotomy between competition as an amoral welfare creating process, that can be the subject of economic research, and the normative concept of fairness does not necessarily lead to a contradiction. Fairness becomes relevant where the competitive process has ceased to play its welfare creating role: i.e. where monopolies prevail over perfect competition. When confronted to a monopoly, abstention is the customer's only choice and for some goods, such as food, clothing and housing, abstention is not considered as a realistic choice. In scenarios where the monopolist faces an inelastic demand curve, fairness is probably the customer's only safety buoy. The energy sector is one of the sectors where these situations occur. In our modern societies, customers expect the light to go on, when they turn the switch, and their houses to be heated, when activating their boilers. Candles and jumpers not offering realistic alternatives, demand is close to inelastic, at least on the short term. Moreover

Highlights: • The activity effect accounts for 98.05% increase in energy use. • Only Eastern’s structural effect contributes energy savings. • Intensity effect contributes energy saving in −4.24% of total energy changes. • Energy-mix effect is insignificant. - Abstract: As one of the three high-energy consumption sectors (industry, building, and transportation) in China, the transport sector faced a devastating resource and environment challenge. The transport sector was reportedly responsible for about 15.9% of the country’s total final energy consumption in 2008. This paper investigates the energy consumption and efficiency of China’s transport sector from 2003 to 2009. The transport energy data of 30 China administrative regions were divided into “three-belts” (Eastern, Western, and Central areas), and the corresponding turnovers were reported and analyzed using an index decomposition analysis (Logarithmic Mean Divisia Index). The energy data and turnover of the transport sector indicated that the high growth rate of turnover results is attributed to the high growth rate of diesel, assuming that diesel is the major fuel for freight transport. The growth of diesel is the main contributor to the overall growth of energy consumption. The growth rate of gasoline has become minimal since 2006. Since 2005, all three-belt areas, with regard to the effectiveness of energy conservation policies, have continuously improved their energy efficiencies based on the results of decomposition analysis. The energy intensity effect shows that the energy conservation and efficiency policies were more effective in the Central and Western areas than that in the Eastern area. On the other hand, the regional shift effect indicates that the policies favor to the Eastern area since only its regional shift effect contributes energy savings since 2008. The energy-mix effect is insignificant, which indicates that it is not necessary to conduct CO 2 emission decomposition

Energy supply options for Lithuania: A detailed multi-sector integrated energy demand, supply and environmental analysis

International Nuclear Information System (INIS)

2004-09-01

The Technical Co-operation (TC) project Energy Supply Options for Lithuania: A Detailed Multi-Sector Integrated Energy Demand, Supply and Environmental Analysis (LIT/0/004) was implemented 2001-2002 by a national team with support from the International Atomic Energy Agency (IAEA). The principal objective of the project was to conduct a comprehensive assessment of Lithuania's future energy supply options taking into consideration the early closure of the Ignalina nuclear power plant (Ignalina NPP). Lithuania, a country in transition to full membership of the European Union, has to comply with the energy acquis (Chapter 14). The 'acquis communautaire' (the body of common rights and obligations which bind all the Member States together) must be adopted by all applicant countries. Implementing the acquis requires not only adequate legislation, well functioning institutions (e.g. a regulatory body as required in the electricity and gas directives) or schedules for restructuring the energy sector but also measures to enhance energy supply security, improvement of energy networks, efficiency improvements throughout the energy system and compliance with European environmental standards. Within the overall context of the transition to EU membership, this study focuses on the future development of the electricity sector and the impacts on energy supply security and environmental performance of a closure of Ignalina NPP by 2009, a pre-condition for accession stipulated by the European Union. The project coincided with the preparation of the new National Energy Strategy for Lithuania and therefore was set up to support the strategy formulation process

Stagnating energy efficiency in the Swedish building sector-Economic and organisational explanations

Naessen, Jonas; Sprei, Frances; Holmberg, John

2008-01-01

The development towards higher energy efficiency in the Swedish building sector stagnated in the late 1980s and 1990s. In new buildings the average specific energy use for heating is twice as high as in the best performing buildings 20 years ago. By combining econometric studies and interviews with actors in the building sector we analyse the underlying economic and organisational causes for this development. In the stock of buildings, specific energy use for heating (kWh/m 2 /yr) has a high correlation with increasing energy prices and price elasticities have not changed markedly over time. This implies that the stagnation to a large extent can be explained by energy price trends. On the contrary, in new buildings the correlation between energy prices and specific energy use is much weaker. One important cause of low sensitivity to price changes is that information about the life cycle cost (LCC) of different investment alternatives is often not available to the involved actors. The most common investment criterion is instead the requirements of the national building energy standard which has developed into a norm rather than a minimum for energy performance. In this paper we also discuss potential improvements in the learning processes within the sector

Strengthening a country's energy supply security is vital in ensuring a long term electricity supply to fulfil the growing energy demand. With the increase of number and resiliency of energy supply options to create a balance energy mix, Malaysia can overcome the national energy security, environmental and sustainable development issues. Introducing nuclear power would increase the diversity of energy supplies as well as increases the efficient use of natural resources in energy sector. This paper presents the use of IAEA energy planning tool, MESSAGE to analyse, simulate and compare energy mix and nuclear option in Malaysia taking into account the national energy policies.

This report on the California Energy Balance version 2 (CALEB v2) database documents the latest update and improvements to CALEB version 1 (CALEB v1) and provides a complete picture of how energy is supplied and consumed in the State of California. The CALEB research team at Lawrence Berkeley National Laboratory (LBNL) performed the research and analysis described in this report. CALEB manages highly disaggregated data on energy supply, transformation, and end-use consumption for about 40 different energy commodities, from 1990 to 2008. This report describes in detail California's energy use from supply through end-use consumption as well as the data sources used. The report also analyzes trends in energy demand for the "Manufacturing" and "Building" sectors. Decomposition analysis of energy consumption combined with measures of the activity driving that consumption quantifies the effects of factors that shape energy consumption trends. The study finds that a decrease in energy intensity has had a very significant impact on reducing energy demand over the past 20 years. The largest impact can be observed in the industry sector where energy demand would have had increased by 358 trillion British thermal units (TBtu) if subsectoral energy intensities had remained at 1997 levels. Instead, energy demand actually decreased by 70 TBtu. In the "Building" sector, combined results from the "Service" and "Residential" subsectors suggest that energy demand would have increased by 264 TBtu (121 TBtu in the "Services" sector and 143 TBtu in the "Residential" sector) during the same period, 1997 to 2008. However, energy demand increased at a lesser rate, by only 162 TBtu (92 TBtu in the "Services" sector and 70 TBtu in the "Residential" sector). These energy intensity reductions can be indicative of energyefficiency improvements during the past 10 years. The research presented in this report provides a basis for developing an energy-efficiency performance index to measure

This paper aims to investigate the sectoral energy use in the Turkish economy for the 1980-2000 period when significant changes occurred in the economic and demographic structure of the country. These changes had several impacts on the energy use in the primary sectors such as agriculture, industry and services. Decomposition analysis is conducted on these sectors by using the additive version of the LMDI method due to its advantages over others. Although a close relationship exists between primary energy consumption and GDP, analyses show that significant variations occurred in the sectoral energy use during the 1982, 1988-1989, 1994 and 1998-2000 periods. Such variations are related to the economic policies of the governments. The Turkish economy has undergone a transformation from agricultural to industrial enhanced by rapid urbanization, especially after 1982. However, industrialization has not been completed yet, and the energy demand should be increasing faster than national income until the energy intensity of the country reaches a peak. This study is performed on three basic sectors; however, decomposition into secondary and tertiary sectors will provide detailed information for further investigations

This paper presents some insights into Jordan's energy consumption in the tourist accommodation sector. The results of a recent survey on environmental performance in the tourist accommodation sector in Jordan were used to evaluate energy conservation in hotels. A survey was designed and distributed to hotels' managers and departments' supervisors in order to understand the environmental performance in the tourist accommodation sector in Jordan during the period 10-17 August 2006. Also some field visits were conducted to fully understand hotels interaction regarding the environment, in addition to help interpreting the results of the survey. The study is limited to all classified hotels in Jordan. It was found that lighting hotels' main building and outside areas, and air conditioning consume more electricity compared to other departments. The results show that few classified hotels already installed energy saving equipments, though, it was noticed that managers of one star hotels were not really willing to make such changes in their hotels, on the other hand, other classified hotels (2-5 star hotels) have shown a high willingness to make changes in their hotels to reduce the consumption of different types of energy. Hotel's classification played a significant role in explaining variations in most of the results, particularly when it comes to long-term investments to reduce energy consumption by using energy efficient appliances. Five and four star hotels were the most hotels willing to use energy efficient appliances to reduce energy consumption. The study suggested some strategies to help reduce the negative impacts of high energy consumption in hotels. These strategies include better insulation, and enhanced insulation for the hot water reticulation system. Moreover, enhancing and increasing the level of awareness among all hoteliers through a directed and well-designed campaign. Also offer interest free loans; and activate precise standards and specifications

Rising energy consumption in coming decades, combined with a changing energy mix, have the potential to increase the impact of energy sector water use on freshwater biodiversity. We forecast changes in future water use based on various energy scenarios and examine implications for freshwater ecosystems. Annual water withdrawn/manipulated would increase by 18-24%, going from 1,993,000-2,628,000 Mm(3) in 2010 to 2,359,000-3,271,000 Mm(3) in 2035 under the Reference Case of the Energy Information Administration (EIA). Water consumption would more rapidly increase by 26% due to increased biofuel production, going from 16,700-46,400 Mm(3) consumption in 2010 to 21,000-58,400 Mm(3) consumption in 2035. Regionally, water use in the Southwest and Southeast may increase, with anticipated decreases in water use in some areas of the Midwest and Northeast. Policies that promote energy efficiency or conservation in the electric sector would reduce water withdrawn/manipulated by 27-36 m(3)GJ(-1) (0.1-0.5 m(3)GJ(-1) consumption), while such policies in the liquid fuel sector would reduce withdrawal/manipulation by 0.4-0.7 m(3)GJ(-1) (0.2-0.3 m(3)GJ(-1) consumption). The greatest energy sector withdrawal/manipulation are for hydropower and thermoelectric cooling, although potential new EPA rules that would require recirculating cooling for thermoelectric plants would reduce withdrawal/manipulation by 441,000 Mm(3) (20,300 Mm(3) consumption). The greatest consumptive energy sector use is evaporation from hydroelectric reservoirs, followed by irrigation water for biofuel feedstocks and water used for electricity generation from coal. Historical water use by the energy sector is related to patterns of fish species endangerment, where water resource regions with a greater fraction of available surface water withdrawn by hydropower or consumed by the energy sector correlated with higher probabilities of imperilment. Since future increases in energy-sector surface water use will occur

Energy use for economic growth: A trivariate analysis from Tunisian agriculture sector

International Nuclear Information System (INIS)

Sebri, Maamar; Abid, Mehdi

2012-01-01

Following the importance of energy in the agrarian economies, the investigation of the causal relationship between energy consumption in agriculture sector and economic growth has a fundamental role in implementing suitable policies. This paper examines the causal relationship between energy consumption and agricultural value added, controlling for trade openness, in Tunisia from 1980 to 2007. The relationship is investigated at aggregated as well as disaggregated components of energy consumption, including oil and electricity. Using Granger's technique, it is shown that various results are obtained regarding the direction of causality between competing variables. Nevertheless, the most common finding suggest that trade openness and both aggregated and disaggregated energy consumption Granger causes agricultural value added. Therefore, the energy-led growth and trade-led growth hypotheses are supported in the Tunisian agriculture sector. An important policy implication resulting from this study is that energy can be considered as a limiting factor to agriculture value added and, therefore, shocks to energy supply would have a negative impact onto agriculture performance. Furthermore, trade liberalization seems to be a stimulus factor to the Tunisian agriculture development. - Highlights: ► We study the energy consumption-economic growth nexus of Tunisian agriculture sector. ► We use Johansen's cointegration approach and Granger causality. ► Energy consumption can be considered as limiting factor to agricultural performance. ► Electrical energy will represent an important input to agricultural production growth.

Among the efforts to slow the potential for climate change are measures to reduce emissions of CO 2 from energy use, and promote long-term storage of carbon in forests and soils. Important environmental changes due to climate change and global warming pose potentially significant risks to humans, social systems, and natural world. Many uncertainties remain regarding precise timing,magnitude, and regional patterns of climate change and the extent to which mankind and nature can adapt to any changes. Estimating technical / economical / environmental potentials for reducing CO 2 emission in energy sector and preventing of global warming is one of the main activities, which have been performed for the first time in Iran. By use of 26 factors, model on global warming combat policies in energy sector of Iran in long-medium and short term determine decreasing amount of CO 2 emission. The results and also method of providing this model will be described in this paper

Conclusion: This preliminary evidence suggests a potential contribution of BRCA1 5382insC mutation to breast cancer development in Uzbek population. Taking into account a high disease penetrance in carriers of BRCA1 mutation, it seems reasonable to recommend inclusion of the 5382insC mutation test in future research on the development of screening programs for breast cancer prevention in Uzbekistan.

The energy sector at a cross roads

International Nuclear Information System (INIS)

2000-01-01

The power and gas markets in Europe are changing radically. Increasing competition and comprehensive structural changes affect the conditions for value creation in the energy sector and the development of the Norwegian energy companies, which are mainly publicly owned. At the same time the demand on the owners is increasing, above all when it comes to strategic vigour in connection with necessary structural changes to adapt the companies to the new market conditions. The development of powerful Norwegian energy companies requires that the owners consider changes in the corporate structures, that the companies are partially privatised and at the same time that the goals of the ownership are clarified and the owner competence strengthened

Protecting ICS Systems Within the Energy Sector from Cyber Attacks

Science.gov (United States)

Barnes, Shaquille

Advance persistent threat (APT) groups are continuing to attack the energy sector through cyberspace, which poses a risk to our society, national security, and economy. Industrial control systems (ICSs) are not designed to handle cyber-attacks, which is why asset owners need to implement the correct proactive and reactive measures to mitigate the risk to their ICS environments. The Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) responded to 290 incidents for fiscal year 2016, where 59 of those incidents came from the Energy Sector. APT groups know how vulnerable energy sector ICS systems are and the destruction they can cause when they go offline such as loss of production, loss of life, and economic impact. Defending against APT groups requires more than just passive controls such as firewalls and antivirus solutions. Asset owners should implement a combination of best practices and active defense in their environment to defend against APT groups. Cyber-attacks against critical infrastructure will become more complex and harder to detect and respond to with traditional security controls. The purpose of this paper was to provide asset owners with the correct security controls and methodologies to help defend against APT groups.

Zinaman, O.; Miller, M.; Bazilian, M.

2014-04-01

This paper seeks to briefly characterize the evolving role of power sector regulation. Given current global dynamics, regulation of the power sector is undergoing dramatic changes. This transformation is being driven by various factors including technological advances and cost reductions in renewable energy, energy efficiency, and demand management; increasing air pollution and climate change concerns; and persistent pressure for ensuring sustainable economic development and increased access to energy services by the poor. These issues add to the already complex task of power sector regulation, of which the fundamental remit remains to objectively and transparently ensure least-cost service delivery at high quality. While no single regulatory task is trivial to undertake, it is the prioritization and harmonization of a multitude of objectives that exemplifies the essential challenge of power sector regulation. Evolving regulatory roles can be understood through the concept of existing objectives and an additional layer of emerging objectives. Following this categorization, we describe seven existing objectives of power sector regulators and nine emerging objectives, highlighting key challenges and outlining interdependencies. This essay serves as a preliminary installment in the Clean Energy Regulatory Initiative (CERI) series, and aims to lay the groundwork for subsequent reports and case studies that will explore these topics in more depth.

Highlights: • We used AHP method to prioritize manufacturing sectors in Serbia. • Priorities for energy management improvement according to five criteria. • Rank 1 – “Manufacture of food products”. • Rank 2 – “Manufacture of motor vehicles, trailers and semi-trailers”. • Rank 3 – “Manufacture of other non-metallic mineral products”. - Abstract: Manufacturing, which is destined to play the most significant role in the reindustrialization of Serbia is also one of the largest energy consumers and environmental polluters. In accordance with this, a large number of energy and environment management initiatives have been implemented over the years. In developed countries, these initiatives are at an advanced level, but not in Serbia. A group of manufacturers in Serbia has recognized the significance of the environmental initiatives implementation, but the interest in energy management improvement has remained low. Although these initiatives can be used to achieve cost reduction in industry, not all the manufacturing sectors equally value the importance of energy management improvement. Among all the manufacturing sectors, it is necessary to prioritize those with the potentials for energy management improvement, which can be done using different methods. In this paper, the AHP (Analytic Hierarchy Process) method was used to prioritize manufacturing sectors in Serbia in the area of energy management improvement. Using a created AHP questionnaires criteria weights were selected. These questionnaires were completed by the experts from the Serbian Chamber of Commerce and Industry, providing us with the opportunity to evaluate the Serbian manufacturing sectors based on the real life data. The results of the AHP method, which was used as the prioritization instrument, and their analysis are presented in the paper. As a part of a wider study, aimed at the improvement of the energy management in Serbia, the three manufacturing sectors with the highest

Energy demand forecasts are often based on assumptions which are uncertain and dependent upon both political and economic factors. However, there is a need for long-term energy forecasting for the benefit of industry and commerce. CIRS (Cambridge Information and Research Services Limited) have tried to fulfill this need, based on forecasts of useful heat demand sector by sector which are then converted to heat energy supply and primary requirements. The first such forecast was produced in 1975. This 1983 updated projection examines coal, oil and gas supplies in the UK to the year 1995.

The paper analyzes the question: is it possible to achieve and what would be the consequences of energy development while reducing CO 2 emissions by 80% by year 2050. Thereby, the growth of costs is not the only expected consequence, but there are also desirable and possible impacts of the energy sector on technological development, science, the economy and increasing the added value. In paper, the development of the energy sector by 2050 is modeled and simulated using two models for the evaluation of the energy systems: model for the analysis of energy consumption (MAED - Model for Energy System Analysis ) and model for optimization of energy supply systems (MESSAGE - Model for Energy Supply Strategy Alternatives and their General Environmental Impacts ). MESSAGE use the results of MAED model as input assumptions and data. Development opportunities in the sectors of industry, households, services and transport were modeled in the simulation, i.e. possible trajectories of development were considered, in order to achieve the objectives of the sectoral reducing of CO 2 emissions in line with the stated objectives which are discussed at the EU level. The average cost of electricity production in year 2050 will increase by nearly 140% compared to the year 2015. The answer is: the reduction of CO 2 emissions in Croatia by 80% in total and by 95% in the power sector is possible from a technical and technological point of view, but with the high financial impact and significant changes in the energy sector, to which should precede changes in scientific and industrial development.(author)

2010-03-19

This report provides a baseline assessment of the current state of energy efficiency-related education and training programs and analyzes training and education needs to support expected growth in the energy efficiency services workforce. In the last year, there has been a significant increase in funding for 'green job' training and workforce development (including energy efficiency), through the American Recovery and Reinvestment Act (ARRA). Key segments of the energy efficiency services sector (EESS) have experienced significant growth during the past several years, and this growth is projected to continue and accelerate over the next decade. In a companion study (Goldman et al. 2009), our research team estimated that the EESS will increase two- to four-fold by 2020, to 220,000 person-years of employment (PYE) (low-growth scenario) or up to 380,000 PYE (high-growth scenario), which may represent as many as 1.3 million individuals. In assessing energy efficiency workforce education and training needs, we focus on energy-efficiency services-related jobs that are required to improve the efficiency of residential and nonresidential buildings. Figure ES-1 shows the market value chain for the EESS, sub-sectors included in this study, as well as the types of market players and specific occupations. Our assessment does not include the manufacturing, wholesale, and retail distribution subsectors, or energy efficiency-focused operations and maintenance performed by facility managers.

This paper provides quantitative information for energy consumption from four different industry sectors based on an energy analysis obtained by means of in-situ energy audits and complementary information. The latter information was taken from Saving Strategy and Energy Efficiency in Spain (Estrategia de Ahorro y Eficiencia Energética en España 2004–2010, E4) documents and the 2009 Industrial Survey of Spain from the National Statistics Institute (Instituto Nacional de Estadística, INE). The results show an estimate of energy consumption for each sector, namely Spanish food, drink and tobacco (9.6%), textile (4.5%), chemical (14.7%), and non-metallic mineral products (24.3%), as well as the degree of inefficiency for each, obtained by means of a stochastic frontier production function model. These results are combined with the energy consumption analysis to identify potential energy saving opportunities around 20.0% of the total energy consumption for all studied sectors. These energy saving opportunities are classified according to thermal or electrical energy consumption and percentage savings of the total energy consumption. -- Highlights: ► This study presents the analysis of four Spanish energy-consuming industrial sectors. ► The four selected sectors account for 33.0% of the total industrial SMEs. ► An audit was carried out in several factories from each analysed industrial sector. ► Stochastic Cobb-Douglas frontiers were used to estimate production frontiers. ► Potential energy saving opportunities around 20.0% of the total energy consumption.

Energy system planning is among the most important tasks of any society. A stable energy system is a foundation for economic growth, growing living standard and general prosperity of the society. Agriculture represents an important factor in overall Croatian economy; therefore, planning of the agriculture's energy system is a major task. To foresee the trend of consumption and to ensure reasonable economic energy supply in accordance with this trend is a process which should be continuously optimised so that the planned scenario could reflect actual situation. The agriculture, thanks to natural resources, land features and climate advantages represents a major economic sector. This activity has significant impact on food industry, trade, tourism, transport, chemical industry, etc. The relevance of agriculture is also visible in the present number of employees, future potential for employment and foreign trade balance. According to numerous parameters, agricultural activities in Croatia lag behind the EU countries. Great potential can be achieved by implementation of measures for energy intensity reduction and productivity increase.(author).

Energy policy and development of the energy sector in Macedonia

Energetics is an important precondition for everyday life in the economic activities as well as the social activities on the whole. The main goal of the energy sector is to monitor and support the planned social development. Consequently, the development of the society and the development of energetics must be coordinated as much as possible. If not, with an autarchic development of the energy system, because of its capital characteristic, could mean a substantial erosion of the social accumulation, without an appropriate contribution to the growth of the national income. Because of this, the issue we wish to speak of is constantly current. (author). 1 tab., 6 ills

Sustainability and Energy Efficiency in the Automotive Sector

CERN Multimedia

CERN. Geneva

2013-01-01

Since this year there can be no doubt that "sustainability" has become the top issue in the automotive sector. Volkswagen's CEO Prof. Dr. Martin Winterkorn attacked incumbents like BMW Group (so far the "most sustainable car manufacturer" for the 8th consecutive year) or Toyota (producer of the famous "Prius") head-on by boldly stating to become "the most profitable and most sustainable car manufacturer worldwide by 2018" . This announcement clearly shows that "sustainability" and "profitability" no longer are considered as conflicting targets. On the contrary, to Prof. Dr. Winterkorn : "climate protection is a driver for economic growth". To prime discussions, the plenary talk will give a brief overview of the entire range of energy efficiency in the automotive sector: based on the multiple drivers behind energy efficiency, practical examples are presented along the entire life-cycle of cars (R&D, production, usage and recycling). These "cases" include big automobile producers as well as their respectiv...

Water is needed mostly in summer time for irrigation and in winter time for generation of electric power. This results in conflicts between downstream countries that utilize water mostly for irrigation and those upstream countries, which use water for generation of electric power. At present Uzbekistan is blocking railway connection that is going to Tajikistan to interfere to transportation of the equipment and materials for construction of Rogun hydropower plant. In order to avoid conflicts between Tajikistan and Uzbekistan a number of measures for the utilization of water resources of the trans-boundary Rivers Amu-Darya and Sir-Darya are discussed. In addition, utilization of water with the supplement of wind and solar energy projects for proper and efficient management of water resources in Central Asia; export-import exchanges of electric energy in summer and winter time between neighboring countries; development of small hydropower project, modern irrigation system in main water consuming countries and large water reservoir hydropower projects for control of water resources for hydropower and irrigation are also discussed. It is also concluded that an effective management of water resources can be achieved by signing Water treaty between upstream and downstream countries, first of all between Tajikistan and Uzbekistan. In this paper management of water as renewable energy resource in Tajikistan and Central Asian Republics are presented. Copyright © 2013. Published by Elsevier B.V.

Danida's support to the energy sector. Issues and contradictions with particular reference to Burkina Faso

Wardell, D.A.

1997-01-01

Danida support to energy sector in Burkina Faso was limited, until 1995, to the electricity sub-sector which has directly benefited less than 5% of the Burkinabe population. Danida made no attempt to develop renewable and local energy resources during the period 1979-1995 although 92% of primary energy supply and 98% of household energy use is met by wood fuels. During 1996 Danida's energy sector programme did, however, include support to strengthen energy policy and planning in Burkina Faso. This will address both wood fuel production systems and the development of new and alternative sources of energy. Danida is currently investigating potential co-financing of a regional traditional energy sector programme with the World Bank and the Netherlands Development Cooperation. A pilot natural forest management project will be initiated in 1997 in the Central-West and Northern Regions of Burkina Faso. A Danida-funded Projet de Developpement Rural dans le Boulgou, initiated in 1996, also includes support to the development and management of natural forest resources. (au)

In accordance with strategic planning in the military, the leader (in this case the Minister of Economy) is responsible for setting goals, finding the right people to accomplish these goals (those working in the energy sector), analysing the current situation (state of the energy sector) and evaluating available resources (conventional and renewable energy resources). In terms of economic planning (this term is proper for an economy that sets numerous laws and quotas), the goal is to get the Polish economy out of economic slump, which is the result of seventeen years of improper government practices, into a state of prosperity corresponding to no less than the European average. The only way of accomplishing this goal of high economic growth and catching up with highly-developed countries is to develop local inexpensive energy resources. This study focuses on the potential to develop abundant Polish geothermal resources as well as natural gas based co-generation. (author)

Assessing the efficiency versus the inefficiency of the energy sectors in formerly centrally planned economies

Energy Technology Data Exchange (ETDEWEB)

Vorsatz, D. [Lawrence Berkeley Laboratory, CA (United States)

1995-12-01

As much the extreme inefficiency of Eastern European energy sectors is emphasized, as little attention their relatively efficient aspects receive. Indeed, a few efficiency indicators show the highest global efficiencies for the formerly centrally planned economies, such as the overall primary to useful energy efficiency. These figures draw the attention to an underestimated feature of former socialist energy sectors and to crucial policy implications: in some respects central planning lead to a more efficient use of energy than the market economy. Consequently, if transitions from the central planning to the market economy are not managed carefully, further reductions in energy efficiency can be expected in some sectors of the economy.

Coleman, John

1994-01-01

The European Bank for Reconstruction and Development was established in 1991 and is owned by the western industrialized countries, including Canada, and the former communist countries of Europe and Central Asia. Its purpose is to assist the latter to make the transition from command to market economies in a democratic framework. In the energy sector, most of the EBRD's lending has been in the oil and gas sector in Russia, but it is open for business in other sectors and in all countries of operation. Unlike other development banks, the EBRD is prepared to finance nuclear power projects. The bank is also prepared to finance conventional power plants where these would permit the closure of obsolete or unsafe nuclear plants. In the oil and gas sector, most of the EBRD's lending has related to private sector, joint venture projects aimed at oil field rehabilitation and development. The private sector ventures supported by the Bank normally involve joint stock companies owned 50 per cent by western partners and 50 per cent by Russian state oil companies, which are being privatized or are operating according to private sector principles.

Khan, Zarrar; Linares, Pedro; García-González, Javier

2016-01-01

The energy sector depends on water in all phases of its life-cycle, including raw material extraction, power plant cooling, irrigation of biofuel crops and directly in hydropower generation. In the coming decades, several regions of the world are expected to experience a decrease in water resource availability, in part due to climate change. The dependence of the energy sector on water resources calls for an active effort to adapt to the possible scenarios. This paper presents a novel model that addresses the direct impacts of regional and temporal water shortages on energy operation and investment decisions. The paper investigates the costs and benefits of adapting the energy sector to climate-induced water scarcity. The results show that the increase in costs for an energy plan that considers future water stress is relatively small as compared to one which ignores it. A plan which ignores water constraints, however, may lead to significant economic damages when actually exposed to water shortages. The results also highlight the value of the availability of water for the energy sector, which is significantly higher than existing prices. The paper concludes that the potential benefits to be gained by integrating energy and water models can be considerable. - Highlights: • Spatial and temporal water constraints are added to an energy planning model. • Integrated water-energy planning can lead to significant savings in future water-stressed scenarios. • Actual value of water for the energy sector may be much higher than existing prices.

China is experiencing intensified industrialisation and motorisation. In the world's largest emerging economy, energy efficiency is expected to play a critical role in the ever-rising demand for energy. Based on factual overviews and numerical analysis, this article carries out an in-depth investigation into the effectiveness of policies announced or implemented in recent decades targeted at energy conservation in the energy intensive manufacturing and transportation sectors. It highlights nine energy intensive sectors that achieved major improvements in their energy technology efficiency efforts. Under the umbrella of the 11th Five-Year Plan, these sectors' performances reflect the effectiveness of China's energy conservation governance. Numerous actions have been taken in China to reduce the road transport sector's demand for energy and its GHG emissions by implementing fuel economy standards, promoting advanced energy efficient vehicles, and alternative fuels. Coal-based energy saving technologies, especially industrial furnace technologies, are critical for China's near and medium-term energy saving. In the long run, renewable energy development and expanding the railway transport system are the most effective ways to reduce energy use and GHG emissions in China. Fuel economy standards could reduce oil consumption and GHGs by 34–35 per cent. - Highlights: • This article makes an investigation into the effectiveness of energy conservation policies in China. • Efficiency improvement reflects the effective governance of energy conservation in China. • Numerous actions have been taken to reduce the road transport sector's demand for energy. • Coal-based energy saving technologies are critical for China's near and medium-term energy saving. • In the long run, renewable energy and expanding the railway transport system are the most effective ways

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

The energy sector in Argentina

International Nuclear Information System (INIS)

2016-01-01

This article first outlines that Argentina produces an important part of its hydrocarbon consumption and comment various aspects of this production: hydrocarbons are at the heart of the Argentinian energetic model; conventional hydrocarbon reserves are however decreasing; the public operator remains the main actor even though the market is opened to multinational companies. The article then describes the crisis faced by this energetic model: the energy balance is now a burden; the increasing unbalance between production and consumption can be explained by supply-related as well as demand-related factors; authorities must intervene on hydrocarbon prices and subsidize the oil price on the domestic market. It appears that the future for hydrocarbons in Argentina relies on non-conventional hydrocarbons. Bio-fuels, a key sector of the Argentinian economy, are a matter of trade dispute with the EU and the USA. Apart from hydroelectricity (some new projects are planned), renewable energies are very few developed in Argentina. Appendices propose a graph of the distribution of energy consumption among the different sources, a map indicating locations of the main exploited hydrocarbon deposits, a presentation of mechanisms implemented to subsidize hydrocarbon production

Rajan, Y.S.; Anil Kumar, B.

1998-01-01

Economic growth is critically dependent on energy which is a key input in all forms of products. With the ecological and environmental concerns for sustainable use of energy, much emphasis is being laid on demand side management, energy efficiency and conservation and alternative sources of energy. This is being witnessed in the long term trends of energy - gross domestic product (GDP) elasticity, which has declined due to changing technology especially for the industrial sector whose share is comparatively reducing in the overall energy consumption. This paper examines mainly the issues involved in meeting the growing demand for electricity, most important form of energy. These issues have been classified as Technical, Financial, Institutional, Policy, Political and International. Each issue is not mutually exclusive of the other and therefore calls for an integrated and holistic approach while addressing them. (author)

The paper analyses the role of renewable energy sources (RES) in the Lithuanian heating sector and the existing support measures. RES consumption has been continuously growing in Lithuania. During the period of 2000–2009, RES used for heat production in the district heating sector increased more than 4 times. Wood and wood products have been the most widely used RES for heat production (RES-H). The lower prices were one of the main reasons which motivated district heating companies to switch fuel to biomass. At the same time subsidies, soft loans, EU Structural Funds for 2007–2013 and some fiscal measures, which are currently available for RES-H promotion, also have some impact on the increase of RES consumption. However, seeking to achieve a 23% national RES target, additional support measures are essential. A qualitative analysis based on the selected set of criteria and consultation with stakeholders showed that energy policy package for RES promotion in the Lithuanian heating sector could encompass the following measures: tax relieves (differentiated VAT and personal income tax breaks), subsidies, soft loans, standardization, support for research, development and demonstration. These measures are market-oriented and meet cost efficiency and low transaction costs criteria. - Highlights: • Existing support measures are not strongly motivating market players. • In order to meet ambitious 23% targets consistent promotion policy package is required. • The proposed package could consist of 4 instruments: tax related, soft loans, standardization and support for RD and D. • The proposed support measures are market oriented and meets cost efficiency and low transaction costs criteria. • There is no single measure that is fairly suitable to support RES-H

Serbia has established a great part of new legislative and institutional framework as a basis for all energy sub-sectors' development in compliance with EU energy acquis. Main objectives of Serbian energy policy outlined in the new Energy Law are focused to increasing the energy supply security, energy efficiency, competitiveness of the energy market, use of renewable energy sources and environmental protection. Further steps of Serbia toward full EU membership concerning the new energy policy regulatory framework involve implementing and enforcing legislation. Besides considering the issue of Serbian energy policy and degree of its framework's alignment with the EU acquis, this paper provides an overview of new development strategies in the oil sector. The aim of Gazprom neft, a majority owner of the Petroleum industry of Serbia, is to increase crude oil production to 3 million tonnes, refining and sales volume of petroleum products to 5 million tonnes by 2020. Strategic development projects in crude oil and petroleum products transportation are: petroleum product pipeline construction in Serbia and Pan-European oil pipeline. The basic prerequisites for oil supply security, regarding the future high dependency of Serbian economy on imported oil, are establishment of the emergency oil stocks and diversification of supply sources. - Highlight: ► New energy policy regulatory framework significantly complied with EU acquis. ► Full EU membership requires implementing and enforcing new energy legislation. ► NIS-Gazpromneft has defined ambitious oil sector's development programmes to 2020. ► Supply security requires mandatory oil stocks and supply source diversification.

Disaggregation of sectoral energy use and greenhouse gas emissions trends reveals striking differences between sectors and regions of the world. Understanding key driving forces in the energy end-use sectors provides insights for development of projections of future greenhouse gas emissions. This report examines global and regional historical trends in energy use and carbon emissions in the industrial, buildings, transport, and agriculture sectors, with a more detailed focus on industry and buildings. Activity and economic drivers as well as trends in energy and carbon intensity are evaluated. The authors show that macro-economic indicators, such as GDP, are insufficient for comprehending trends and driving forces at the sectoral level. These indicators need to be supplemented with sector-specific information for a more complete understanding of future energy use and greenhouse gas emissions.

The German Federal Government wants to see electromobiles make a substantial contribution to sustainable mobility and to reducing fossil fuel consumption. Its scenario for the market entry of the electromobile envisages a market penetration of one million vehicles by the year 2020 and of 5 million by the year 2030. How will the increased electricity demand accompanying this development impact on the energy sector, and what will the effects be on sector-specific CO{sub 2} emissions? In order to answer these questions one first has to look at potential energy and load requirements on power plants and electricity grids.

An estimated 2.5 billion people remain without access to modern energy supplies. This shortfall is expected to grow as the population in developing countries continues to grow rapidly and the existing infrastructure ages. The United Nations' goal of lowering poverty by half by 2015 will not be attained unless the poor in developing countries gain greater access to basic infrastructure and services, including energy services. The key objective of this paper is to analyze trends in overseas development assistance (ODA) to the energy sector in developing countries during the period 1990-2003, relative to realized private sector investments. This analysis then forms the basis for policy recommendations for consideration by decision makers within countries that are major contributors to ODA
