Coal-fired power plants, which produce almost half of the country's electricity, have significant impacts on water quantity and quality in the United States. Water is used to extract, wash, and sometimes transport the coal; to cool the steam used to make electricity in the power plant; and to control pollution from the plant.

United States: Despite electricity demand increasing in the United States, coal-fired generation fell by almost 8% in 2022, reversing a 15% increase in 2021. The decrease in coal output was balanced by an increase in generation from natural gas and strong growth in renewables. As a result, coal's share of total global generation remained around ...

Coal fired power plants follow the Rankine cycle in order to complete this process. Since they require plenty of water to be circulated in this cycle, coal power plants need to be located near a body of water. The process of coal fired plants can be seen below in Figure 3. Figure 3. The process of a coal fired power plant to convert coal into ...
