COAL 115 Poland and South Africa maintain large amounts of coal exports, yet each nation does not account for even 1% of the world's coal reserves 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 71, 81 and 91) This suggests that, when supplies of gas and petroleum become scarce, it South Africa relies most heavily on coal, taking 93 percent of its electric power from this energy source China and India also rely heavily on coal for substantial amounts of their energy, at 79 percent and 69 percent, respectively The US takes 45 percent of its electricity from this source, ranking it 11th on the global list of countries that generate power from this source Types of Coal The Types of Coal: Composition, Usage, and Energy Value
