Available in PDF, EPUB and Kindle. Book excerpt: China has experienced tremendous growth in the production and sales of room air conditioners over the last decade. Although minimum room air conditioner energy efficiency standards have been in effect since 1989, no efforts were made during most of the 1990's to update the standard to be more reflective of current market conditions. In 1999, China's State Bureau of Technical Supervision (SBTS) included in their annual plan the development and revision of the 1989 room air conditioner standard, and experts from SBTS worked together with LBNL to analyze the new standards. Based on the engineering and life cycle-cost analyses performed, the most predominant type of room air conditioner in the Chinese market (split-type with a cooling capacity between 2500 and 4500 W (8500 Btu/h and 15,300Btu/h)) can have its efficiency increased cost-effectively to an energy efficiency ratio (EER) of 2.92 W/W (9.9 Btu/hr/W). If an EER standard of 2.92 W/W became effective in 2001, Chinese consumers would be estimated to save over 3.5 billion Yuan (420 million U.S. dollars) over the period of 2001-2020. Carbon emissions over the same period would be reduced by approximately 12 million metric tonnes.

China consumes one fourth of the world's energy currently, however its per capital consumption is no more than half of that in OECD countries. This book provides a comprehensive treatment of the situation of China's energy development, proposes and summarizes the methodologies of energy efficiency measurement, and uses these methods to analyze the energy consumption at sectoral and provincial level, the impacts of economic structure on the energy macro-efficiency, the price elasticity of oil demand, and energy efficiency policies simulations. The book provides scientific support for researchers and policy makers dealing with energy efficiency.
Book Synopsis Project Completion Report on China's Room AC Reach Standard by : Jiang Lin
Download or read book Project Completion Report on China's Room AC Reach Standard written by Jiang Lin and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: After much anticipation and hard work, China's reach standard for room air-conditioners was announced in September 2004, with the first tier going into effect on March 1, 2005 and the reach standard taking effect on January 1, 2009. This is a major milestone in the development of minimum energy efficiency standards in China: finally China has set a minimum standard that is meaningful and stringent. According to our preliminary analysis, the majority of room ACs products on the Chinese market in 2004 would not meet the 2009 reach standard requirement. In addition to setting the minimum requirement, China's new AC standard also include classification requirement for the newly established Energy Information Label, as well as the certification requirement for CECP's Energy Conservation Label. Highlights of the 2009 reach standard include: (1) The Chinese Reach Standard for Room AC in 2009 is tighter than American counterpart, and almost matches the efficiency of American Central Air-Conditioners; and (2) Summer peak demand reduction in 2020 due to the reach standard exceeds the capacity of the Three Gorges Project.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years China's energy consumption has increased rapidly. The problem of high energy consumption intensity and low energy utilization efficiency is serious, and the contradiction between economic development and energy and environmental resources has become increasingly acute, making energy conservation and consumption reduction an important society-wide concern. At the same time, global climate change has and will continue to have profound impacts on human survival and development, and is another major challenge to all countries. In order to accelerate China's energy conservation and emission reduction work, the National Leading Group to Address Climate Change, Energy Conservation and Emission Reduction was founded with Premier Wen Jiabao as the head, and the 'Comprehensive Work Program of Energy Conservation and Emission Reduction' and 'China's National Program of Addressing Climate Change' were issued, under which China's energy conservation and emission reduction work has been fully deployed. Efforts to promote energy efficiency have been further strengthened in all levels of government, and various policies and measures have progressively been issued and implemented. In addition, based on China's experience with implementing energy-saving priority strategies over the past 20+ years, our government established a goal of a 20% decrease in energy consumption per unit GDP in the 'Eleventh Five-year Development Plan'. Furthermore, in November 2009, in order to support global greenhouse gas emission reduction activities and promote China's low carbon economic development, the government established a further 40-50% reduction in energy consumption per unit GDP by 2020 compared to the year 2005. Improving energy utilization efficiency by scientific and technological progress will undoubtedly play an important role in achieving the above stated objectives. The improvement of energy efficiency of energy consuming products has always been an important component of all countries energy strategies. As we all know, a very large amount of total energy consumption is due to energy consuming products and equipment, which account for about 50% of China's total energy consumption. However, the current average energy utilization efficiency of this sector is only about 60%, 10 percent lower than the international advanced level. Therefore, China's energy consuming products and equipment sector holds great energy-saving potential. On the other hand, the energy supplied to these products is mainly from fossil fuel combustion, a major source of greenhouse gas (GHG) emissions. Therefore, improving the energy efficiency and augmenting the market share of market-dominant energy consuming products is of significant importance to achieving China's energy saving and emission reduction target and is an effective means to deal with energy and environmental constraints and climate change issues. Main energy consuming products generally include widely-used home appliances, industrial equipment, office equipment, transportation vehicles, etc. China is one of the major manufacturers and exporters of energy end-using products such as air-conditioners, refrigerators, televisions, etc. Their overall energy efficiency is comparatively low and the products are poorly designed, leading to great energy-saving potential. For example, electricity consumption of air conditioners accounts for about 20% of China's total electricity consumption and 40% of the summer electricity peak load in large and medium cities. However, less than 5% of units sold in the domestic market in 2009 reached the standard's highly efficient level of grade 2 above. The electricity consumption of electric motors and their related drive systems accounts for about 60% of China's total electricity consumption; however, less than 2% of the domestic market share consists of energy-efficient electric motor products. Promoting the energy efficiency and market shares of main energy-consuming products has become an important determinant of achieving energy conservation and emission reduction targets throughout the world.

Book Synopsis Energy Efficiency in Household Appliances by : Paolo Bertoldi
Download or read book Energy Efficiency in Household Appliances written by Paolo Bertoldi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is widespread interest throughout the world in improving appliance energy efficiency. Methods to reach that end include energy labeling, energy efficiency standards and market conditioning (e.g, energy efficient procurement and DSM programs). Energy efficiency standards, which started out as an action to reduce demand for energy in individual countries, has now become a subject of regional and even worldwide dimension, particularly in the context of global climate change mitigation. Mandatory energy efficiency standards are in place for some appliances in China, Canada, Mexico, the Philippines and the United States. Standards for refrigerator/freezers will take effect in Australia and the European Union in 1999. Voluntary energy efficiency standards are in place for refrigerators in Brazil, India and Korea and for air conditioners in India, Japan and Korea. Table I showed potential global energy use reductions from codes and standards in buildings. If individual country data can be assembled, a more accurate approach to estimating potential reductions in energy use and carbon emissions would be to perform a bottom-up analysis for energy using equipment on an end-use basis in as many large developing countries as possible. The impact of standards would be assessed as more efficient appliances replaced existing stock models and new purchases that increased saturation rates were made at higher efficiencies than would otherwise be the case. This approach would show the slow but steady buildup of annual energy savings from efficiency standards or other programs to improve energy efficiency.

Available in PDF, EPUB and Kindle. Book excerpt: "The world needs ever increasing energy supplies to sustain economic growth and development. But energy resources are under pressure and CO2 emissions from today's energy use already threaten our climate. What options do we have for switching to a cleaner and more efficient energy future? How much will it cost? And what policies do we need? This second edition of Energy Technology Perspectives addresses these questions, drawing on the renowned expertise of the International Energy Agency and its energy technology network. This publication responds to the G8 call on the IEA to provide guidance for decision makers on how to bridge the gap between what is happening and what needs to be done in order to build a clean, clever and competitive energy future. The IEA analysis demonstrates that a more sustainable energy future is within our reach, and that technology is the key. Increased energy efficiency, CO2 capture and storage, renewables, and nuclear power will all be important. We must act now if we are to unlock the potential of current and emerging technologies and reduce the dependency on fossil fuels with its consequent effects on energy security and the environment. This innovative work demonstrates how energy technologies can make a difference in an ambitious series of global scenarios to 2050. The study contains technology road maps for all key energy sectors, including electricity generation, buildings, industry and transport. Energy Technology Perspective 2008 provides detailed technology and policy insights to help focus the discussion and debate in energy circles."--Cover.

Book Synopsis Modeling the Economics of Greenhouse Gas Mitigation by : National Research Council
Download or read book Modeling the Economics of Greenhouse Gas Mitigation written by National Research Council and published by National Academies Press. This book was released on 2011-02-24 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models are fundamental for estimating the possible costs and effectiveness of different policies for reducing greenhouse gas (GHG) emissions. There is a wide array of models to perform such analysis, differing in the level of technological detail, treatment of technological progress, spatial and sector details, and representation of the interaction of the energy sector to the overall economy and environment. These differences impact model results, including cost estimates. More fundamentally, these models differ as to how they represent fundamental processes that have a large impact on policy analysis-such as how different models represent technological learning and cost reductions that come through increasing production volumes, or how different models represent baseline conditions. Reliable estimates of the costs and potential impacts on the United States economy of various emissions reduction and other mitigation strategies are critical to the development of the federal climate change research and development portfolio. At the request of the U.S. Department of Energy (DOE), the National Academies organized a workshop, summarized in this volume, to consider some of these types of modeling issues.
