我国是能源消费大国,但我国的能源储备相对短缺,石油和天然气等资源每年都要依靠进口。其次我国能源利用率低,以建筑业为例,在每平方米建筑中的能源消耗量为发达国家的两倍左右。为了给我国经济的快速发展提供保证,缓解能源的供需矛盾,节约能源和利用再生能源迫在眉睫。 China is a big energy consumer. However, China’s energy reserves are relatively short and resources such as oil and natural gas rely on imports every year. Second, China’s low energy efficiency, the construction industry, for example, in every square meter of building energy consumption for developed countries about twice. In order to provide a guarantee for the rapid economic development in our country, it is imminent to ease the contradiction between supply and demand of energy and to save energy and use renewable energy.
