The term 'black coal' is used in Australia to refer to anthracite, as well as bituminous and sub-bituminous coals (Table 3.7). Black coal is higher in energy and has lower moisture content than brown coal. Brown coal, also called lignite, is a low-ranked coal with high moisture content that is used mainly to generate electricity.

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. The total energy consumption in the United States for 1990 was 86 x 10 15 kJ. Of this total, 41% came from oil, 24% from natural gas, and 23% from coal.
