随着社会逐步进入“低碳”时代,节能和减排愈来愈成为当今社会上热议的两大主题。电力作为经济社会发展的基础动力,在各项能源消耗中所占比例越来越大,开展节能降耗工作,将对快速进入“低碳社会”产生着重要作用。我国是一个能源大国,同时又是一个人口大国,人均能源占有量远低于世界平均水平。煤炭、石油、天然气等一次能源的人均剩余可采储量只有世界平均水平的58.6%、7.69%和7.05%,而我国当前正处在工业化、城镇化水平高速发展时期,能源资源的需求量很大。据2006年统计数字显示,我国 With the gradual entry of society into the “low-carbon” era, energy saving and emission reduction have increasingly become the hot topics in today’s society. As the basic driving force of economic and social development, electricity accounts for an increasing proportion of various energy consumption. To carry out energy conservation and consumption reduction will play an important role in rapidly entering the “low-carbon society.” Our country is a big energy country and a populous country with a per capita energy share far below the world average. The per capita recoverable reserves of primary energy such as coal, oil and natural gas are only 58.6%, 7.69% and 7.05% of the world average respectively. However, China is in a period of rapid development of industrialization and urbanization with a large demand for energy resources . According to the statistics of 2006, our country
