Coal - Types, Uses and Formation - VEDANTU

lignite: The carbon content in lignite coal is about 25-35% and has a low energy content among all the coal types known. Lignite has a high moisture content which contributes to its low heating value. Only 9% of the lignite coal was mined in the USA in the year 2020 among which 54% was mined in North Dakota and 39% was mined in Texas.

Coal explained - U.S. Energy Information Administration (EIA)

Lignite contains 25%-35% carbon and has the lowest energy content of all coal ranks. Lignite coal deposits tend to be relatively young and were not subjected to extreme heat or pressure. Lignite is crumbly and has high moisture content, which contributes to its low heating value. Lignite accounted for 9% of total U.S. coal production in 2020.
