Geothermal energy can heat, cool, and generate electricity: geothermal energy can be used in different ways depending on the resource and technology chosen—heating and cooling buildings through geothermal heat pumps, generating electricity through geothermal power plants, and heating structures through direct-use …
What Is Geothermal Energy Used For?
Geothermal energy can be used for space heating and cooling in a variety of ways. One common method is to use a geothermal heat pump (GHP) to extract heat from the ground and use it to heat a building.
GHPs can be used for both new construction and retrofits, and are particularly well suited for buildings with large heating and cooling loads, such as schools and office buildings.
Another way to use geothermal energy for space heating and cooling is to direct the heat from a geothermal power plant into a district heating system.
This can be done by using a heat exchanger to transfer the heat from the power plant to a fluid in the district heating system, which then circulates through a network of pipes to deliver heat to buildings connected to the system.
District heating systems using geothermal energy are particularly common in Iceland, where they are used to heat more than 90% of all buildings.
Domestic Hot Water Geothermal energy can also be used to heat water for domestic use. This can be done using a GHP,
