Burning coal provided the necessary heat energy to convert a tank of water into steam. The steam was converted to mechanical energy and channeled out to power machines in industrial mills and factories. Therefore steam became the new form of energy source that substituted conventional water, wind, and animalpower operations.

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...
