Some kinds of coal were used for coke, others for power. It all depends on the actual chemical make-up of the coal itself. For example, the coal out of the Powder River Basin is used for power, as it yields little ash. This coal was considered worthless for the steel industry because its not good for coking. It wasn't until emissions standards were tightened that it had any use.
