Coal was the second highest energy source at about 23%. The vast majority of coalfired power plants rely on steam turbines. Petroleum, on the other hand, accounted for less than 1% of electricity generation in 2019. Some steam turbines are powered by residual fuel oil and petroleum coke. However, these can also be burned in gas turbines.

In the, uranium is mined from sandstone deposits in the same regions as coal. Wyoming and the Four Corners region produce most uranium. The mining process is similar to coal mining, with both open pit and underground mines. It produces similar environmental impacts, with the added hazard that uranium mine tailings are radioactive.

The conversion of this coal to the end goal of electricity is a multifaceted process: The coal must be unloaded from the train. Traditional ways of doing this require the use of cranes picking up the coal from the cars, however newer plants have the floor underneath the train tracks drop away, allowing the coal to be dropped into underground containment.

In both cases a power source is used to turn a propellerlike piece called a turbine, which then turns a metal shaft in an electric generator, which is the motor that produces electricity. A coalfired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.
