据美刊《能源工程》1993年第11期报道,国际能源机构最近的调查报告说,近年来,天然气作为石油替代能源的重要性,逐渐被许多国家所接受。 到1992年为止的五年间,美国对天然气的需求量增加13.5％,达到19.53万亿立方英尺。而且,在克林顿总统倡导使用天然气的情况下,美国今后的需求量将会进一步增加。据调查,1991年美国对天然气的需求量在一次能源中所占的比重力23.7％,而到2000年将增至24.5％,到2010年将增加到25.5％。
According to the U.S. publication “Energy Engineering”, No. 11, 1993, the recent IEA survey report said that in recent years, as the importance of alternative energy sources for petroleum, natural gas has gradually been accepted by many countries. In the five years up to 1992, the U.S. demand for natural gas increased by 13.5% to 19.53 trillion cubic feet. Moreover, with President Clinton advocating the use of natural gas, the U.S. demand will further increase in the future. According to the survey, the U.S. demand for natural gas in primary energy accounted for 23.7% of the total primary energy in 1991 and will increase to 24.5% by 2000 and 25.5% by 2010.
