Fascinating Facts about Geothermal Systems
- The first recorded geothermal system was a 1912 Swiss patent.
- The ground absorbs 47% of the sun’s energy that reaches planet Earth. This amount of energy represents 500 times more than mankind needs every year.
- About half a million geothermal systems have been installed since 1980.
- Installing a geothermal system in a typical home is equal, in greenhouse gas reduction, to planting an acre of trees, or taking two cars off the road.
- Current geothermal installations save more than 14 million barrels of crude oil per year.
- If one in 12 California homes installed a geothermal system, the energy saved would equal the output of nine new power plants.
