能源是国民经济发展的动力,与人民生活密切相关,是实现四个现代化的根本环节之一。当前,世界上常规能源之一——石油已十分紧张。很多专家认为除常规能源(煤、油、气等)、新能源(核能、太阳能、地热能、潮汐能等)外,应把节能工作所节省的能源称之为“第三能源”。因此,节能即开发“第三能源”。 Energy is the driving force for the development of the national economy and is closely linked to people’s livelihood. It is one of the fundamental links in the realization of the four modernizations. At present, one of the world’s conventional energy sources - oil has been very tight. Many experts believe that energy saved from energy conservation should be called “the third energy source” in addition to conventional energy (coal, oil, gas, etc.) and new energy sources (nuclear energy, solar energy, geothermal energy, tidal energy, etc.) Therefore, energy conservation is the development of “third energy.”
