Geothermal power plants use hot water and/or steam located underground to produce electrical energy. The hot water and/or steam are brought to the surface where heat exchangers are used to produce clean steam in a secondary system for use with turbines. Clean steam causes no sediment growth inside pipes and other equipment, thereby minimizing maintenance.
The clean steam is converted into electrical energy much the same way as in typical fossil fueled steam plants.
Although geothermal energy is considered to be a good renewable source of reliable power, some are concerned that over the long term, the availability of this geothermal resource for power plants may be reduced over time(it may dry up, become less availabile, or lose pressure). A typical geothermal power plant is shown in Figure.
