Geothermal energy is heat energy originating deep in the earth's molten interior. It is this heat energy which is responsible for volcanoes, movement of tectonic plates and earthquakes. The temperature in the earth's interior is as high as 7000 0C, decreasing to 650-1200 0C at depths of 80 km-100 km. Hot dry rock (HDR) is a heated geological formation usually composed of granites at depths of 3 to 5 kilometres. This enormous energy resource can be tapped by introducing water to a specially prepared HDR reservoir and extracting it as high-pressure steam to run conventional steam turbine power equipment. Large potential exists for hot dry rock electricity production in the central and eastern areas of Australia and a number of companies are developing proposals to establish projects in these regions.
