The heat that originates in the earth is known as geothermal energy. The Greek words “therme,” which means heat, and “geo,” which means earth, are combined to form the term “geothermal.” Geothermal energy exists in underground reservoirs of steam, hot water, and hot rock beneath the earth.
This geothermal heat has been utilized by humans for thousands of years. Geothermal energy is currently used in three different ways.
It can be used to warm buildings directly, to bathe in some places, and it can be used to generate electricity in geothermal power plants. The heat is accessed by drilling wells into geothermal reservoirs beneath the ground. In some places, this heat is close to the surface, so it is easier to access.
Is geothermal energy renewable?
Yes, geothermal energy is a renewable resource. The earth just produces heat year-round, like the slow breakdown of minerals deep within the earth. This is to say the geothermal supply never runs out like fossil fuels.
Provided the earth’s heat is utilized effectively, it will be dependable for many years. In well-managed systems, the subterranean water or steam is pumped back into the reservoir to help maintain temperature and pressure.
This will enable geo-thermal energy to be utilized further for extended periods without changing the underground reservoir.
