1998-6-25  Of the three fossil fuels in common use natural gas, petroleum, and coal the United States has far more coal than gas and petroleum (compare Figures 7-1, 8-1 and 9-1). This suggests that, when supplies of gas and petroleum become scarce, it would be possible to turn to coal as our major fossil fuel energy resource.
