Geothermal Energy
Geothermal energy is the natural heat from the earth’s interior stored in rocks and water within the earth’s crust. The main source of this
energy is the constant flow of heat from the earth’s interior to the surface. This heat creates the molten rock, or magma, beneath the surface
crust. Volcanoes, geysers and fumaroles are the visible evidence of the great reservoir of heat, which lies within and beneath the earth’s
crust. The magma heats the surrounding rock structures and when underground water comes into contact with this heat, geothermal fluid is
formed. This energy can be extracted by drilling wells to tap concentrations of steam at high pressures and at depths shallow enough to be
economically justifiable. The steam is then led by pipes to drive electricity-generating turbines. At an international level,
approximately 8,100 MW of geothermal power is generated, out of a global potential of 60,000 MW.
