Frequently Asked Questions (FAQs) - U.S. Energy Information

In 2019, power plants that burned coal, natural gas, and petroleum fuels were the source of about 62% of total U.S. electricity generation, but they accounted for 99% of U.S. electricity-related CO2 emissions. The other 1% of CO2 emissions were from other fuels and gases derived from fossil fuels and some types of geothermal power plants.

How to Calculate the Coal Quantity Used in a Power Plant

The first part of the conversion is efficiency of the boiler and combustion. For this example we take 88 % on an HHV basis that is the normal range for a well-optimized power plant. Second part is the steam cycle efficiency. Modern Rankine cycle, adopted in coal fired power plants, have efficiencies that vary from 32 % to 42 %.

Do coal power plants produce waste (burned coal)?

Coal burning power plants produce a waste product called fly ash. It is commonly used as an ingredient in cement products. If the power plant has flue gas desulpherization, the byproduct from that process is gypsum which is used in making gypsum wallboard (drywall).
