    Bituminous coal, or soft coal, contains between 69% and 86% carbon by weight and is the most abundant form of coal. Sub-bituminous coal contains less carbon and more water, and is therefore a less efficient source of heat. Lignite coal, or brown coal, is a very soft coal that contains up to 70% water by weight.
