What does Geothermal mean ?

The word Geothermal comes from 2 Greek words Geo and Therm . Geo means Earth and Therm means heat from the Earth.

Where is it Found ?

The distance to the center of the earth is approximately 4000 miles and it is so hot that it is molten. There is a type of rock which becomes molten and it is called Magma. Magma is just below the thin layer of the Earth that layer is called Crust. And Igneous rocks are formed from the solidification of molten rock material. Mostly some of the geothermal areas are found near volcanos or earthquaes because this is where the major plate boundries are located

Where can Geothermal Energy be used ?

  • Energy For Houses

Most Common Geothermal Systems in Houses

How is Geothermal energy used in houses ?

First of all a house uses a geothermal heat pumpwhich both cools and heats the house,or a direct geothermal energy which only keeps the house warm . The major parts of the geothermal pump is an underground loop which is a heating pipe and a heating despencer.A deep hole is dug to place the pipes it is important to dig deep to reach the right amount of energy is supplied .
