Germany's three lignite mining regions | Clean Energy Wire
Germany has been the largest lignite producer in the world since the beginning of industrial lignite mining. It still is, followed by China, Russia, and the United States. The softer and moister lignite (also called brown or soft coal) has a lower calorific value than hard coal and can only be mined in opencast operations. When burned, it is more CO2 intensive than hard coal.

Lignite has a lower BTU level than any other type of coal; therefore, it burns faster and contains less heat energy than harder coals (anthracite, bituminous, and subbituminous). During the first part of the Cenozoic Era, which began about 65 million years ago, the last of the seas that had covered North Dakota drained away.

Lignite - an overview | ScienceDirect Topics
Lignite, or brown coal, is the lowest-ranked coal, and is placed just above peat in terms of calorific value. It is not a feature of international seaborne coal trades, primarily due to its high water content (which can reach up to 60 per cent) and its lower Btu values (which average 4000–8300 Btu/lb compared with bituminous coals, which average 8500–14 000 Btu/lb).
