Where it can be found
Geothemal energy can be found in heat within the Earth
How it works
Groundwater is heated by magma, then becomes steam or hot water. The steam or water is discharged into the air by geysers or natural vents. Geothermal power plants then harness energy from within the Earth by pumping steam and hot water.
DiFferent types of Them
There are 3 different types of geothermal power plants.
- Dry steam power plant: used to generate power directly from steam
- Flash steam power plants: get hot water inside the Earth and convert it to steam, most geothermal plants are flash steam plants
- Binary cycle power plants: Transfer heat from geothermal hot water to another liquid.
