Geothermal power is energy generated by heat stored in the earth or the collection of absorbed heat derived from underground in the atmosphere and oceans. Prince Piero Ginori Conti tested the first geothermal generator on 4 July 1904 at the Larderello dry steam field in Italy. 1 The largest group of geothermal power plants in the world is located in The Geysers a geothermal field in California. 2 As of 2008 geothermal power supplies less than 1% of the worlds energy. 3
