CT: Geothermal power plants have much in common with traditional power-generating stations. They use many of the same components, including turbines, generators, transformers, and other standard power generating equipment. While there are three types of geothermal power plants, this animation shows a generic plant.

N: 1. geothermal (adj): 1875, from geo– (word-forming element meaning “earth,” ultimately from Greek geo-, comb. form of ge “earth”) + thermal (1756, “having to do with hot springs,” from French thermal (Buffon), from Greek therme “heat, feverish heat,” from PIE gwher- “to heat, warm”; sense of “having to do with heat” is first recorded 1837; the noun meaning “rising current of relatively warm air” is recorded from 1933).
power (n): c.1300, “ability; ability to act or do; strength, vigor, might,” especially in battle; “efficacy; control, mastery, lordship, dominion; legal power or authority; authorization; military force, an army,” from Anglo-French pouair, Old French povoir, noun use of the infinitive, “to be able,” earlier podir (9c.), from Vulgar Latin potere, from Latin potis “powerful”. Sense of “electrical supply” is from 1896.
station (n): late 13c., “place which one normally occupies,” from Old French stacion, estacion “site, location; station of the Cross; stop, standstill,” from Latin stationem (nominative statio) “a standing, standing firm; a post, job, position; military post; a watch, guard, sentinel; anchorage, port” (related to stare “to stand”), from PIE ste-ti-, suffixed form of root sta- “to stand”. The meaning “place where people are stationed for some special purpose” (as in polling station) is first recorded 1823.
2. A power station or plant that converts geothermal energy into electrical energy.
3. The first geothermal power station was built at Landrello, in Italy, and the second was at Wairekei in New Zealand
4. There are three types of geothermal power plants: dry steam, flash steam, and binary cycle.
