人类从技术发展之初直至20世纪60年代末,共消耗了850亿t标准燃料,且其中半数是在1940-1970年之间开采的。如果说20世纪初的燃料动力资源仅有1%用于发电,那么到20世纪末,这一数字则接近50%。现将可转化为电能的世界动力潜能有关数据做一比较。 Humans consumed 85 billion tons of standard fuel from the beginning of technology until the end of the 1960s and half of them were mined between 1940 and 1970. If only 1% of the fuel-power resources in the early 20th century were used to generate electricity, by the end of the 20th century that figure was close to 50%. A comparison is now made of the relevant data on the world’s power potential that can be converted into electricity.
