The word geothermal comes from the Greek words geo (earth) and therme (heat). So, geothermal energy is heat from within the earth. We can use the steam and hot water produced inside the earth to heat buildings or generate electricity. Geothermal energy is a renewable energy source because the water is replenished by rainfall and the heat is continuously produced inside the earth Geothermal energy is generated in the earth's core, about 4,000 miles below the surface. Temperatures hotter than the sun's surface are continuously produced inside the earth by the slow decay of radioactive particles, a process that happens in all rocks. The earth has a number of different layers The core itself has two layers: a solid iron core and an outer core made of very hot melted rock, called magma. The mantle which surrounds the core and is about 1,800 miles thick. It is made up of magma and rock. The crust is the outermost layer of the earth, the land that forms the continents and ocean flo ...more

Power obtained by using heat from the Earth's interior. Most geothermal resources are in regions of active-volcanism. Hot springs, geysers, pools of boiling mud, and fumaroles (vents of volcanic gases and heated groundwater) are the most easily exploited sources of such energy. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in some geothermal regions of the world, such asIceland, Turkey, and Japan. The greatest potential for geothermal energy, however, lies in the generationof electricity. Geothermal energy was first used to produce electric power at Larderello, Italy, in 1904. Bythe late 20th century, geothermal power plants were in operation in Italy, New Zealand, Japan, Iceland, Mexico, the United States, and elsewhere, and many others were under construction in other countries. The most useful geothermal resources are hot water and steam trapped in subsurface formations or reservoirs and having temperatures ranging from 176 to 662 F ...more

Geothermal power is energy generated from heat stored in the earth, or the collection of absorbed heat derived from underground.
