Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses

What are the Uses of Coal? Electricity production is the primary use of coal in the United States. Most of the coal mined in the United States is transported to a power plant, crushed to a very small particle size, and burned. Heat from the burning coal is used to produce steam, which turns a generator to produce electricity.
