Editing Power station (section)

====By heat source====
* [[Fossil-fuel power station]]s may also use a steam turbine generator or in the case of natural [[gas-fired power plant]]s may use a [[gas turbine|combustion turbine]]. A coal-fired power station produces heat by burning coal in a steam boiler. The steam drives a [[steam turbine]] and [[electric generator|generator]] that then produces [[electricity]]. The waste products of combustion include ash, [[sulfur dioxide]], [[nitrogen oxides]], and [[carbon dioxide]]. Some of the gases can be removed from the waste stream to reduce pollution. 
* [[Nuclear power plant]]s<ref>[http://www.iaea.org/cgi-bin/db.page.pl/pris.oprconst.htm Nuclear Power Plants Information] {{Webarchive|url=https://web.archive.org/web/20050213081431/http://www.iaea.org/cgi-bin/db.page.pl/pris.oprconst.htm |date=13 February 2005 }}, by [[International Atomic Energy Agency]]</ref> use the heat generated in a [[nuclear reactor]]'s core (by the [[Nuclear fission|fission]] process) to create steam which then operates a steam turbine and generator. About 20 percent of electric generation in the US is produced by nuclear power plants.
* [[Geothermal power]] plants use steam extracted from hot underground rocks. These rocks are heated by the decay of radioactive material in the Earth's core.<ref>{{Cite web |last=Roberts |first=David |date=2020-10-21 |title=Geothermal energy is poised for a big breakout |url=https://www.vox.com/energy-and-environment/2020/10/21/21515461/renewable-energy-geothermal-egs-ags-supercritical |access-date=2022-04-13 |website=Vox |language=en |archive-date=4 February 2023 |archive-url=https://web.archive.org/web/20230204142009/https://www.vox.com/energy-and-environment/2020/10/21/21515461/renewable-energy-geothermal-egs-ags-supercritical |url-status=live }}</ref>
* [[Biomass#Energy|Biomass-fuelled power plants]] may be fuelled by [[bagasse|waste from sugar cane]], [[Incineration|municipal solid waste]], landfill [[methane]], or other forms of [[biomass]].
* In integrated [[steel mill]]s, [[Blast furnace gas|blast furnace exhaust gas]] is a low-cost, although low-energy-density, fuel.
* [[Cogeneration|Waste heat from industrial processes]] is occasionally concentrated enough to use for power generation, usually in a steam boiler and turbine.
* [[Solar thermal energy|Solar thermal]] electric plants use sunlight to boil water and produce steam which turns the generator.
* [[Combined cycle hydrogen power plant|Hydrogen power plant]]s can use [[green hydrogen]] from [[Electrolysis of water|electrolysis]] to help balance supply and demand from [[Variable renewable energy]] sources.<ref>{{cite magazine|url=https://www.powermag.com/ready-for-the-energy-transition-hydrogen-considerations-for-combined-cycle-power-plants/|title=Ready for the Energy Transition: Hydrogen Considerations for Combined Cycle Power Plants|first=Sebastian|last=Mulder|date=Oct 29, 2021|magazine=Power}}</ref>
