What is geothermal energy used for?

Geothermal energy captures the heat from deep under the ground and uses it to produce electricity. This electricity is added to the grid and is sold to consumers.

Geothermal energy is also used in domestic situations to warm or cool individual buildings.

A:First of all, you have the geothermal heat pump; this is where you are going to have three levels of geothermal. Geothermal heat pumps are pretty much used for heating and cooling. So that can be in any heating and cooling application that you can think of. That could include snow melting where pipes are buried in concrete slabs. There are some applications around where we have greenhouses that use the hot water directly for heating. There is an agricultural application, which is fish farming. There have been uses of crop drying, like tomato drying and garlic and onion drying. Some people are using a geothermal heat to produce ethanol and bio-fuels. There are all kinds of processes like that; any process that uses high temperature of heat, say below 200 Fahrenheit. When we get above that, we can use geothermal power plants to drive turbines to make electricity.
