Great pressure results in the creation of bituminous, or "soft" coal. This is the type. most commonly used for electric power generation in the U.S. It has a higher heating value than either lignite or sub-bituminous, but less than that of anthracite. Bituminous coal is mined chiefly in the Midwest & Appalachia.
