对京津区域1980-1992年间能源利用状况进行分析,并通过模式计算该区域大气污染物的扩散规律,结果表明,大气污染物随能源利用增加而增加,其增加速率NOx大于OS2,经预测,至2004年京津地区SO2排放量增咖11.40%,NOx增加56.80%,由于气象和地形条件所致,该区域内不利于大气污染物远距离输送,这使箱型区域内物料平衡计算可以简化。  相似文献

This paper aims to assess the renewable energy capacity of Turkey in order to consider main priorities in the energy policy of Turkey. In this paper, renewable energy potential and regulatory conditions are discussed in Turkey in comparison with European Union. The results of the study implemented within the framework of EnviroGRIDS project indicated a promising yet very susceptible future for the implementation of renewable energy power plants in Turkey. The forecasts have shown that the solar power potential utilization is becoming more significant after 2020. The projections for 2050 indicate that electricity consumption from small and medium renewable energy sources including solar and wind will constitute 15% of the total, whereas the solar thermal will constitute around 16%. Geothermal and other renewables will remain around 3%. According to the high demand scenario, in 2050 the share of hydropower in overall electricity generation will be 12%, followed by solar power at 7% and wind power at 3%. Additionally, renewable energy policy and regulations in Turkey and in EU are overviewed in this study. On the contrary to EU, the constant feed-in tariff amount does not consider capital investments of specific energy sources in Turkey that brings disadvantage to the implementation. However, new regulations published and currently applied should be accepted as milestones in acquisition period of Turkey in EU.  相似文献

美国联邦政府从20世纪30年代开始制定能源监管立法。依据集中程度和立法主题,美国能源监管立法可分为电力管控、核能监管、能源安全、放松管制等4个发展时期。根据现行美国能源立法.美国能源管理体制分为联邦和州两个层次。在联邦层次,对能源进行监管的部门有美国能源部、联邦能源监管委员会、核能监管署、环境保护署、国会内政部等。其中,能源部主要负责能源发展和安全的大政方针的制定,联邦能源监管委员会的使命在于通过管制和市场的手段执行能源立法及能源政策。在州层次,一般由州能源委员会、州公用事业委员会以及州环保局负责州的能源监管。  相似文献

This article investigates how a mix of energy-users from Denmark perceives energy and environmental issues such as the affordability of electricity and gasoline, the seriousness of climate change, and preferences for different energy systems. Its primary source of data is a pilot survey and energy literacy test distributed in English and Danish to 328 respondents spread across the country. The survey results are used to test four propositions about energy prices, being “green,” public knowledge and competence about energy issues, and self-sufficiency and sustainable technology. The data supports the propositions that Danes identify with “being green” and prefer national and local policies that endorse sustainable technology and being self-sufficient. However, the data also challenges the propositions that Danes would prioritize low energy prices and affordability as key energy concerns and that they are knowledgeable about energy and environmental issues. In this way, a problematic gap may exist between what many academic articles (and previous surveys) report Danish attitudes to be and what this study suggests they are. Given Denmark's ambitious low-carbon goals, these findings have clear relevance to other communities and countries seeking to decarbonize their own energy sectors.  相似文献

US residential and commercial buildings were responsible for about 41 exajoules (EJ) of primary energy use per year in 2002, accounting for approximately 9% of the world fossil-fuel related anthropogenic carbon (C) emissions of 6.7 Gt that contribute to climate change. US Government-sponsored building energy efficiency research and implementation programs are focused on reducing energy consumption in US residential and commercial buildings and reducing these carbon (C) emissions. Although not specifically intended for adaptation to a warmer climate and less effective than under today’s cooler climate, these programs also could help reduce energy demand in a future warmer world. Warming scenarios projected by the United Nations Intergovernmental Panel on Climate Change (IPCC) in 2001 imply net overall decreases in both site energy and primary energy consumption in US residential and commercial buildings, largely because of the reduced need for heating. However, there would be as much as a 25% increase in building space cooling demand and a significant part of the increase could be offset by energy-efficiency improvements in buildings. Overall, in the US, buildings-related energy efficiency programs would reduce site energy consumption in buildings in the US by more than 2 EJ in 2020 and primary energy by more than 3.5 EJ, more than enough to offset the projected growth in cooling energy consumption due to climate change and growth in the US building stock. The savings would have an estimated annual net value at 2005 energy prices of between $45.0 and $47.3 billion to consumers.

Scenario analysis of energy-based low-carbon development in China   总被引:1,自引:0,他引:1  
China's increasing energy consumption and coal-dominant energy structure have contributed not only to severe environmental pollution,but also to global climate change. This article begins with a brief review of China's primary energy use and associated environmental problems and health risks. To analyze the potential of China's transition to low-carbon development,three scenarios are constructed to simulate energy demand and CO2 emission trends in China up to 2050 by using the Long-range Energy Alternatives Planning System(LEAP) model. Simulation results show that with the assumption of an average annual Gross Domestic Product(GDP) growth rate of 6.45%,total primary energy demand is expected to increase by 63.4%,48.8% and 12.2% under the Business as Usual(BaU),Carbon Reduction(CR)and Integrated Low Carbon Economy(ILCE) scenarios in 2050 from the 2009 levels. Total energy-related CO2 emissions will increase from 6.7 billion tons in 2009 to 9.5,11,11.6 and11.2 billion tons; 8.2,9.2,9.6 and 9 billion tons; 7.1,7.4,7.2 and 6.4 billion tons in 2020,2030,2040 and 2050 under the BaU,CR and ILCE scenarios,respectively. Total CO2 emission will drop by 19.6% and 42.9% under the CR and ILCE scenarios in 2050,compared with the BaU scenario.To realize a substantial cut in energy consumption and carbon emissions,China needs to make a long-term low-carbon development strategy targeting further improvement of energy efficiency,optimization of energy structure,deployment of clean coal technology and use of market-based economic instruments like energy/carbon taxation.  相似文献
