Coal

Coal-To-Gas Plant Conversions in the U.S. In particular, the demand for power generation from certain fuels is driven by cyclical factors. Coal, natural gas, oil, renewables and other fuels have come in and out of vogue at different times over the years for various reasons, usually driven by costs of a particular fuel or regulations that tend to favor one fuel over another.

Coal-fired 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.

Third, coal consumption is far more concentrated than the use of other fossil fuels.

Thus, reducing emissions from coal is a far simpler task.
