Geothermal Heat - The Forgotten Alternative Energy Source
June 30th, 2006The earth’s core is 60 times hotter then your boiling water. This produces an enormous pressure on the earth. And even just some miles down, heat can already be felt. Thus, the geothermal heat can be extracted without digging right through the earth’s core. In fact, digging 3 miles down can achieve 100 degrees Celsius, enough to produce steam which is essential factor to produce power.
The process goes this way: Instead of using coal or oil or other fossil fuel, a geothermal power plant uses superheated fluids geothermal source to produce energy, energy that is then converted to electricity.
