Energy Density of Coal - The Physics Factbook

Eighty six percent of the coal burned in the United States is used by power plants to make energy for electricity. When the coal is burned by the power plants, energy produced is in the form of heat. When coal is used by the steel industry, it is first heated and turned into a substance called coke, which is almost pre carbon.

Lignite - Wikipedia

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It is considered the lowest rank of coal due to its relatively low heat content. It has a carbon content around 60–70 percent.
