A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal, oil, or natural gas, to produce electricity. Fossil fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical generator. The prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine. All plants use the energy extracted from the expansion of a hot gas, either steam or combustion gases. Although different energy conversion methods exist, all thermal power station conversion methods have their efficiency limited by the Carnot efficiency and therefore produce waste heat.
Homer City Generating Station is a decommissioned 2-GW coal-burning power station near Homer City, in Indiana County, Pennsylvania, USA. It is owned by hedge funds and private equity firms and is operated by NRG Energy. Units 1 and 2, rated at 660 MWe, began operation in 1969. Unit 3, rated at 692 MWe nameplate capacity, was launched in 1977. It employed about 124 people.

The Robert W. Scherer Power Plant is a coal-fired power plant in Juliette, Georgia, just north of Macon, Georgia, in the United States. The plant has four generating units, each capable of producing 930 megawatts, and is the most powerful coal-fired plant in North America. The plant is named after the former chairman and chief executive officer of Georgia Power.
The Acid Rain Program is a market-based initiative taken by the United States Environmental Protection Agency in an effort to reduce overall atmospheric levels of sulfur dioxide and nitrogen oxides, which cause acid rain. The program is an implementation of emissions trading that primarily targets coal-burning power plants, allowing them to buy and sell emission permits according to individual needs and costs. In 2011, the trading program that existed since 1995 was supplemented by four separate trading programs under the Cross-State Air Pollution Rule (CSAPR). On August 21, 2012, the United States Court of Appeals for the District of Columbia issued its Opinion and Order in the appeal of the Cross State Air Pollution Rule (CSAPR) for two independent legal reasons. The stay on CSAPR was lifted in October 2014, allowing implementation of the law and its trading programs to begin.
Marshall Steam Station is a coal power plant located at 35°35′51″N80°57′53″W in Sherrills Ford, Catawba County, North Carolina, United States and owned by Duke Energy. Named for former company president E.C. Marshall, the station is located on Lake Norman and began commercial operation in 1965.
The Castle Gate mine disaster occurred on March 8, 1924, in a coal mine near the town of Castle Gate, Utah, located approximately 90 miles southeast of Salt Lake City. All of the 171 men working in the mine were killed in the series of three violent explosions. One worker, the leader of the rescue crew, died from carbon monoxide inhalation while attempting to reach the victims shortly after the explosion.
A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide there are over 2,400 coal-fired power stations, totaling over 2,130 gigawatts capacity. They generate about a third of the world's electricity, but cause many illnesses and the most early deaths, mainly from air pollution. World installed capacity doubled from 2000 to 2023 and increased 2% in 2023.
Coal generated about 19.5% of the electricity at utility-scale facilities in the United States in 2022, down from 38.6% in 2014 and 51% in 2001. In 2021, coal supplied 9.5 quadrillion British thermal units (2,800 TWh) of primary energy to electric power plants, which made up 90% of coal's contribution to U.S. energy supply. Utilities buy more than 90% of the coal consumed in the United States. There were over 200 coal powered units across the United States in 2024. Coal plants have been closing since the 2010s due to cheaper and cleaner natural gas and renewables. Due to measures such as scrubbers air pollution from the plants kills far fewer people nowadays, but deaths in 2020 from PM25 have been estimated at 1600. Environmentalists say that political action is needed to close them faster, to also reduce greenhouse gas emissions by the United States and better limit climate change.

The former plant is situated directly across the Ohio river from Petersburg, Boone County, Kentucky. Tanner's Creek was one of the two Indiana coal power plants owned by Indiana Michigan Power, a subsidiary of American Electric Power.
