Geothermal power is power extracted from heat stored in the earth. This geothermal energy originates from the original formation of the planet and from radioactive decay of minerals.
The direct application of this energy is space heating, through the use of geothermal heat pumps that collect and exchange underground heat with domestic spaces. In this way a field around your home can suddenly work as an incredible energy tank which can always be exploited.
Geothermal power is environmentally friendly, cost effective, reliable and sustainable; moreover, a geothermal installation is very long lasting (over 100 years), very silent, and it needs no upkeep.
