Bituminous coal was first commercially mined in Pennsylvania at Coal Hill Mount Washington just across the Monongahela River from the city of Pittsburgh The coal was extracted from drift mines in the Pittsburgh coal seam which outcrops along the hillside and energy sources and nuclear energy are forecast to increasingly contribute to the primary energy supply coal will remain our major energy source into the foreseeable future due to its relative abundance and low cost Geology and coal quality of the South African coalfields Coal is found in South Africa

Graphite will burn only at high temperatures and is therefore not useful as an energy source Anthracite coal produces the most energy when burned with less energy produced by bituminous coal and lignite Coal is found in beds called seams usually ranging in thickness from 05 to 3m although some seams reach 30 m The major coal producing 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
