There is a strong correlation between net energy yield (NEY) and energy return on investment (EROI). Although a few studies have researched the EROI at the extraction level in China, none have calculated the EROI at the point of use (EROIPOU). EROIPOU includes the entire energy conversion chain from extraction to point of use. To more comprehensively measure changes in the EROIPOU for China’s conventional fossil fuels, a “bottom-up” model to calculate EROIPOU was improved by extending the conventional calculation boundary from the wellhead to the point of use. To predict trends in the EROIPOU of fossil fuels in China, a dynamic function of the EROI was then used to projections future EROIPOU in this study. Results of this paper show that the EROIPOU of both coal (range of value: 14:1–9.2:1), oil (range of value: 8:1–3.5:1) and natural gas (range of value: 6.5:1–3.5:1) display downward trends during the next 15 years. Based on the results, the trends in the EROIPOU of China’s conventional fossil fuels will rapidly decrease in the future indicating that it is more difficult to obtain NEY from China’s conventional fossil fuels.

At the First Extraordinary Meeting of the Forum of Ministers of the Environment of Latin America and the Caribbean, Johannesburg, August 2002. An initiative for sustainable development in Latin America and the Caribbean was presented. This proposes that the countries of the region should show in their energy distribution minimum participation of 10% of renewable energy sources in the Total Primary Energy Supply (OTEP). The mechanism of action of this initiative is not based on penalizing countries that their natural conditions are not favorable for energy sustainability, but on promoting greater participation of renewable energy sources. Through the analysis of the country's energy demand and energy sources and according to the initiative, the Colombian government, through its entities, organizes programs to improve its energy efficiency and the participation of renewable energy sources and technologies, not conventional. This paper shows the statistics of energy distribution and energy sources in Colombia. Based on this information, we seek to identify the deficient sectors with their problems to implement strategies at the national level that allows them to meet the proposed goals.

In article assessment of tendencies and prospects of cooperation between Ukraine and the European Union in the field of renewable energy sources was carried out. Over the past decades, the theme of climate change, especially caused by human activity, has become one of the most acute and most exploited in scientific disputes. Today, the problem of finding new sources of energy is more than acute, with a special place occupy non-traditional ones. The reduction of Ukraine's energy dependence on traditional fuel resources is possible only through the development and use own alternative energy, which uses local resources – bioenergy as a fuel or does not require a fuel component at all – solar, wind and small hydropower. The European Union is one of the leaders in the implementation of alternative energy and renewable energy sources and initiates the creation of many organizations that finance alternative energy projects. Ukraine should ensure the effective convergence of its own legislation with the European Union, since it defined the European integration vector as a priority area of foreign policy development. At the same time, within the framework of the Union, the mechanism of environmental protection and progressive approaches to the implementation of energy policy, including in the field of renewable energy, can serve as the most constructive benchmarks for Ukraine's development in this area. Ukraine signed the Paris Agreement, and undertook certain commitments, namely: in accordance with the National Action Plan on alternative energy up to 2020, the objective was to reach 11% of RES in gross final energy consumption. Achieving this goal is possible only in the case of international cooperation with the EU in the field of alternative energy. However, today, the study of the prospects of cooperation between Ukraine and the EU in this field is not developing sufficiently and there is a certain vacuum in solving strategic problems in this context, which determines the relevance of the topic.

Before the current economic crisis hit the Europe and Central Asia (ECA) region in 2008, energy security was a major source of concern in Central and Eastern Europe and in many of the economies in the former Soviet Union. Energy importers were experiencing shortages leading to periodic brownouts and blackouts. An energy crisis seemed imminent. This report analyzes the outlook for energy demand and supply in the region. It estimates the investment requirements and highlights the potential environmental concerns associated with meeting future energy needs, including those related to climate change. The report also proposes the actions necessary to create an attractive environment for investment in cleaner energy. Greater regional cooperation for smart energy and climate action is an important part of the World Bank's engagement in Europe and Central Asia.

India has 150GW of renewable energy potential, about half in the form of small hydropower, biomass, and wind and half in solar, cogeneration, and waste-to-energy. Developing renewable energy can help India increase its energy security, reduce the adverse impacts on the local environment, lower its carbon intensity, contribute to more balanced regional development, and realize its aspirations for leadership in high-technology industries. This study aims to answers critical questions on why renewable energy development is relevant in Indian context, on how much development is economically feasible, and on what needs to be done to realize the potential. The Report is based on data from nearly 180 wind, biomass, and small hydropower projects in 20 states, as well as information from the Ministry of New and Renewable Energy (MNRE) and the Central Electricity Regulatory Commission (CERC).The Report suggests that about 3GW of renewable energy ? all from small hydropower is conomically feasible, when the avoided cost of coal-based generation of Rs 3.08/kWh is considered. About 59GW of renewable energy in wind, biomass, and small hydropower is available at less than Rs 5/kWh. The entire cumulative capacity of 68GW in these three technologies can be harnessed at less than Rs 6/kWh. About 62GW?90 percent of cumulative renewable capacity in wind, biomass, and small hydropower?is economically feasible when the environmental premiums on coal are brought into consideration. Realizing the need to bridge this gap, the government has set an ambitious target of installing at least 40GW of additional capacity of renewables in the next 10 years. India has made tremendous strides in establishing overarching policy framework and institutions to bring renewable in the mainstream of energy mix, but significant financial, infrastructure and regulatory barriers to renewable energy development remain which the report sheds light on and suggests possible solutions.

This article discusses historical patterns of energy supply, electricity generation, and sectoral energy consumption as well as the emission of energy-related greenhouse gases during 1995–2008 in 5 Hindu Kush–Himalayan countries, Bangladesh, Bhutan, India, Nepal, and Pakistan, and reviews major studies that predict energy use and greenhouse gas emissions during 2005–2030 in the absence of climate policy interventions. It presents a range of energy use and greenhouse gas emission projections for the selected countries as a whole, and for the Hindu Kush–Himalayan areas in those countries for 2030. This study shows a need to establish a spatially disaggregated (district-level) energy database in the Hindu Kush–Himalayan countries to enable more accurate estimates of energy use and associated greenhouse gas emissions in the region.

These report overviews recent developments in the consumption and production of bioenergy. It examines the main issues and possible economic implications of these developments and assesses their potential impact on land use and the environment, especially with respect to forests. The report examines both solid biomass and liquid biofuels, identifying opportunities and challenges at the regional and country levels. The development of bioenergy presents both opportunities and challenges for economic development and the environment. It is likely to have significant impacts on the forest sector, directly, through the use of wood for energy production, and indirectly, as a result of changes in land use. The impact of bioenergy on poverty alleviation in developing countries will depend on the opportunities for agricultural development, including income and employment generation, the potential to increase poor peoples' access to improved types of bioenergy; and the effects on energy and food prices. Five main messages emerge from this report: solid biomass will continue to be a principal source of energy; developments in bioenergy will have major implications for land use; tradeoffs, including those related to poverty, equity, and the environment, must be evaluated when choosing a bioenergy system; there is considerable potential for making greater use of forestry and timber waste as a bioenergy feedstock; and the climate benefits of bioenergy development are uncertain and highly location and feedstock specific.

The decoupling conditions of GDP and Total Primary Energy Supply (TPES) for the BRICS in the period 1971-2008 were analyzed. It is concluded that in the studied period, the decoupling indicators of China and Russia are relatively higher than that of Brazil, South Africa and India. The BRICS’s decoupling distribution is similar to China, because China accounts for most part of TPES and GDP of the BRICS. To restrain the total resource or energy consumption from increasing too fast, it is suggested to match the indicators of GDP growth and the decreasing rate of resource consumption per unit of GDP appropriately.

Countries heavily dependent on imported oil to power a significant portion of their electricity generation are especially vulnerable to high and volatile oil prices. In net oil-importing countries worldwide, high and volatile oil prices ripple through the power sector to numerous segments of the economy. As prices move up and down, so does the cost of electricity production, which has far-reaching effects on the economy, fiscal and trade balances, businesses, and household living standards. High and volatile oil prices affect economies at both a macro and micro level. The major direct effects at the macro level are a deteriorating trade balance, through a higher import bill, reflecting a worsening in terms of trade; and a weakening fiscal balance due to greater government transfers and subsidies to insulate movements in international energy markets. At the micro level, investment uncertainty results from the higher risk of engaging in new projects and associated development and sunk costs, which, in turn, affects policy decisions and economic growth. This study responds to the needs of policy makers and energy planners in oil-importing countries to better manage exposure to oil price risk. The study's objective is threefold. First, it analyzes the economic effects of higher and volatile prices on oil-importing countries, with emphasis on the power sector, using examples from Latin America and the Caribbean (LAC). Second, it proposes a menu of complementary options that can be applied over multiple time frames. Several structural measures are designed to reduce oil generation and consumption, while a range of financial instruments are suggested for managing price risk in the short term. Finally, it attempts to quantify some of the macroeconomic and microeconomic benefits that could accrue from implementing such options.

At the end of 2011, the Indian power sector found itself in financial crisis, just a decade after the 2001 bailout of state electricity boards (SEBs) by the central government. Bankrupt state power distribution utilities in several states were unable to pay their bills or repay their debts. Despite the passage of the landmark 2003 Electricity Act and implementation of a broad set of reforms over the past decade, the sector today is looking at another rescue from the center, four times larger than before. This financial rescue scheme amounts to about Rs 1.9 trillion ($42 billion) and was instigated by the nonperforming assets of the banks and other financial institutions. The Electricity Act was envisaged to create independent companies functioning on commercial principles, but they are still far away from that goal. This report presents a diagnostic of the financial and operational performance of segments in the power sector value chain between adoption of the Electricity Act, 2003, and 2011, including analysis of the factors that contributed to the recent crisis. The report focuses on efficiency and productivity, whether performance has improved over time, and which states have emerged as performance leaders. Analysis of this kind is not new or unique, but this report aims to integrate historical performance, the current situation, future projections of the impact of worsening sector finances, and the actions that need to be taken to check the downturn. The report draws primarily from utility data collected by the Power Finance Corporation in successive years on utilities operational and financial performance. The Power Finance Corporation data were collated into a single database with the addition of various operational parameters at the plant level and the utility level from the Central Electricity Authority.
