1982年全世界能源消耗总量大约相当7C～75亿吨石油,而在1925年全世界能源总量仅仅相当10亿吨石油。据经济学家预测,到2000年全世界能源总量将相当130～135亿吨石油。 就全世界而言,除西方高度发达的工业国家外,其它地区能源消耗量将有大幅度增加。迄今为止,在全世界所需要的能源中,地下能源占能源总需要量的90％。到2000年,如
In 1982, the total energy consumption in the world was about 7C ~ 7.5 billion tons of oil, while in 1925, the total amount of energy in the world was only 1 billion tons of oil. According to economists, by the year 2000, the total amount of energy in the world will be equivalent to 1.3-135 billion tons of oil. As far as the rest of the world is concerned, energy consumption in other regions will increase significantly except for the highly developed industrial countries in the West. To date, underground energy sources account for 90% of the total energy requirements of the world’s total energy needs. By 2000, as
