What is Geothermal Energy ?


Dated: Nisan 6th, 2009

The word geothermal comes from the greek words geo (earth) and therme (heat). Geothermal energy is heat from within the earth.

Geothermal energy is generated in the earth’s core, almost 4,000 miles beneath the earth’s surface.The double-layered  core is made up of very hot magma (melted rock) surrounding a solid iron center. Very high temperatures  are continuously produced inside the earth by the slow  decay of radioactive particles. This process is natural in all rocks.

Geothermal energy is called a renewable energy source because the water is replenished by rainfall  and the heat is continuously produced deep within the earth. We won’t run out of geothermal energy . Future generations will still have geothermal energy.
