Question

how and where is the thermal energy derived?​

Answer 1

Answer:

Geothermal energy is nothing more than heat from the Earth. ... To extract geothermal heat, the hot water is pumped out of the deep subsoil and the heat is extracted using a heat exchanger. The cooled water is then pumped back and eventually heats up again because of the heat in the Earth.

Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth's surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity.
