Geothermal Energy Description
Geothermal heat is the heat that comes from the earth’s core. This clean and sustainable form of energy is a result of its fiery consolidation of dust and gas that has been brewing for over 4 billion years. Temperatures at the core of our earth may reach over 9,000 degrees Fahrenheit.
The heat from the core of earth is always trying to radiate outward. It conducts it heat through the various layers of the earth until it reaches the earth’s crust. Geothermal energy technology is based upon our ability to utilize this radiating heat to serve our energy consumption requirements.
Geothermal Energy Growth
Geothermal power has increased by an average of about 3 - 4% per year over the past decade. However the growth rate seems to be increasing as we notice that in the past 5 years, the energy production from geothermal sources increased by over 13% year over year.
