Coal prices and outlook - U.S. Energy Information ...

2020-5-26 · Lignite is the lowest rank of coal and has the lowest energy content. Lignite is crumbly and has high moisture content. Lignite accounted for about 8% of U.S. coal production in 2019. Subbituminous coal has a higher heating value than lignite. Subbituminous coal typically contains 35%–45% carbon, compared with 25%–35% for lignite.
