Petroleum and Coal Purdue UniversitySubbituminous 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.
