====By prime mover====
A prime mover is a machine that converts energy of various forms into energy of motion.
* [[Steam turbine]] plants use the dynamic pressure generated by expanding steam to turn the blades of a turbine. Almost all large non-hydro plants use this system. About 90 percent of all electric power produced in the world is through use of steam turbines.<ref name="Wiser">{{Cite book |last=Wiser |first=Wendell H. |url=https://books.google.com/books?id=UmMx9ixu90kC&pg=PA190 |title=Energy resources: occurrence, production, conversion, use |publisher=Birkhäuser |year=2000 |isbn=978-0-387-98744-6 |page=190 |access-date=21 November 2015 |archive-date=23 January 2023 |archive-url=https://web.archive.org/web/20230123202054/https://books.google.com/books?id=UmMx9ixu90kC&pg=PA190 |url-status=live }}</ref>
* [[Gas turbine]] plants use the dynamic pressure from flowing gases (air and combustion products) to directly operate the turbine. Natural-gas fuelled (and oil fueled) combustion turbine plants can start rapidly and so are used to supply "peak" energy during periods of high demand, though at higher cost than base-loaded plants. These may be comparatively small units, and sometimes completely unmanned, being remotely operated. This type was pioneered by the UK, [[Pocket Power Stations|Princetown]]<ref>[http://www.swehs.co.uk/docs/news13su.html SWEB's Pocket Power Stations<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20060504055822/http://www.swehs.co.uk/docs/news13su.html |date=4 May 2006 }}</ref> being the world's first, commissioned in 1959.
* [[Combined cycle]] plants have both a gas turbine fired by natural gas, and a steam boiler and steam turbine which use the hot exhaust gas from the gas turbine to produce electricity. This greatly increases the overall efficiency of the plant, and many new baseload power plants are combined cycle plants fired by natural gas.
* Internal combustion [[reciprocating engine]]s are used to provide power for isolated communities and are frequently used for small cogeneration plants. Hospitals, office buildings, industrial plants, and other critical facilities also use them to provide backup power in case of a power outage. These are usually fuelled by diesel oil, heavy oil, [[natural gas]], and [[landfill gas]].
* [[Gas turbine#Microturbines|Microturbines]], [[Stirling engine]] and internal combustion reciprocating engines are low-cost solutions for using opportunity fuels, such as [[landfill gas]], digester gas from water treatment plants and waste gas from oil production.{{Citation needed|date=July 2021}}
