This is a list of the 220 operational coalfired power stations in the United States. Coal generated 23% of electricity in the United States in 2021, [1] an amount similar to that from renewable energy or nuclear power, [2] [3] but about half of that generated by natural gas plants. Coal was 19% of generating capacity. [4]

If the FC/VM ratio ranges between and, the coal is subbituminous, supporting lowload operation (VM >22 per cent). If the ratio ranges between and, the coal will have difficulty in supporting low load operation (VM < 20 per cent). The FC/VM ratio also influences flame stability and emission of nitrogen oxides (NOx).

Coal Pollution, Emissions, Climate Change: Coal is abundant and inexpensive. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years. There are, however, a variety of problems associated with the use of coal. Mining operations are hazardous. Each year hundreds of coal miners lose their lives or are ...
