The four types of coal are peat, lignite, bituminous, and anthracite. ... Lignite has a higher heat content than peat but is still not the most desired form of coal. However, lignite makes up almost half of our known coal reserves. Bituminous coal is formed as more pressure is applied to lignite coal.
