Geothermal is a clean (no fossil fuel consumption) form of renewable energy that involves our sun heating the earth beneath our feet. Our earth absorbs 50% of the sun’s energy – more than 500 times more energy than mankind needs every year.
Through a geothermal system (geo for earth and thermal for the heat from the sun) we use that energy in the ground to heat and cool our homes.
Geothermal is possible because the temperature of the earth at 4-6 ft. below ground remains relatively constant year-round.
Geothermal is the most efficient form of heating and cooling that exists.
Geothermal systems save over 40 trillion tons of heat units a year.
Geothermal systems eliminate almost 6 million metric tons of carbon dioxide from the air every year.
A geothermal heating-cooling system saves enough energy in one year to mow 925 football fields.
In 2014 geothermal systems will reduce America’s dependence on imported fossil fuels by over 21 million barrels of crude oil a year.
Today’s use of geothermal systems is equivalent to planting over 385 million trees. And removing 1,295,000 cars from the road.
Geothermal systems are not affected by clouds or darkness, by wind or lack of it, and are operational 24 hours a day, 365 days a year for as long as the earth and sun last.
