长期以来,化石能源支撑着工业文明发展,同时也带来了环境污染、气候变化等影响人类生存发展的现实难题。能源消费总量不断攀升,传统能源供应日益趋紧,全球能源资源竞争越来越激烈,国际能源价格高位震荡,生态环境等制约因素凸显,要求建立在化石能源基础上的能源生产和消费方式亟待转变。电能作为清洁、高效、便捷的二次能源,可以有效提高能源利用效率、促进清洁能源的发展、提高电气化水平。 For a long time, fossil fuels have supported the development of industrial civilization, and brought about practical problems that affect the survival and development of mankind, such as environmental pollution and climate change. The total energy consumption continues to rise, the traditional energy supply is tightening day by day, the global energy resources competition is more and more fierce, the international energy prices fluctuate high, the ecological environment and other constraints highlight the fate of energy production and consumption based on fossil fuels change. As a clean, efficient and convenient secondary energy, electric energy can effectively improve the energy efficiency, promote the development of clean energy and improve the electrification level.
