能源是人类社会经济发展的物质基础之一。长期以来,由于大量使用煤炭、石油等化石能源,带来两大问题是:这些化石物质在燃烧过程中,排放了大量有害有毒物质,严重地污染了环境;二是地球上这些资源的储存量是有限的,专家们指出,如继续大量使用石油,按现有储量,则五六十年后石油资源将枯竭,已探明可开采的天然气约可维持六七十年,储量丰富的煤,预计也只有三百年左右的开采寿命。面对能源与环境的双重挑战,研究开发利用清洁和可再生的新能源已在世界发达国
Energy is one of the material bases for the economic development of human society. For a long time, due to the extensive use of fossil fuels such as coal and oil, two major problems are caused by the fact that these fossil fuels emit large amounts of harmful and toxic substances during combustion, which seriously pollute the environment. Second, the storage of these resources on Earth Are limited. Experts point out that if large quantities of oil are to be used and existing reserves are used, oil resources will be depleted in 50-60 years. Proven recoverable natural gas will last for about 60-70 years, with abundant reserves of coal, Expected only about three hundred years of mining life. Faced with the dual challenges of energy and the environment, research and development and utilization of clean and renewable new energy sources have been developed in the world’s developed countries
