Types of Coal. There are four main categories for coal based on the amounts of carbon it contains and the heat energy it can produce. The bituminous and anthracite types of coal typically contain more heat-producing energy. Lignite: Over time, heat and burial pressure turn peat into lignite. Lignite is somewhat light in color, soft and crumbly.
