目前,人类实际应用的主要能源还是化石能源.煤、石油、天然气等化石能源的利用,对人类生存、发展、进步产生过巨大的影响.进入21世纪后,人们更加注重生存环境和生存空间的质量.大量燃用化石能源产生的温室效应、酸雨现象对人类生存环境造成了严重破坏.同时,化石能源经长期开采,其资源日趋枯竭,已不足以支撑全球经58 At present, the main energy actually used by humans is fossil energy. The use of fossil fuels such as coal, oil, and natural gas has had a tremendous impact on human survival, development, and progress. After entering the 21st century, people have paid more attention to the living environment and living space. Quality. The greenhouse effect and acid rain caused by the massive use of fossil fuels have caused serious damage to the living environment of human beings. At the same time, the long-term exploitation of fossil energy resources has become increasingly depleted and it is insufficient to support the global economy.
