  • Environmental impacts of coal - SourceWatch

    Coal-fired power plants are responsible for one-third of America’s carbon dioxide (CO2) emissions—about the same amount as all transportation sources -- cars, SUVs, trucks, buses, planes, ships, and trains -- combined. A 1000 megawatt (MW) coal-fired power plant produces approximately the same amount of global warming as 1.2 million cars.

  • TVA - How a Coal Plant Works

    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.
