Renewable energy resources of NSW Geothermal Map (A3)

Potential geothermal energy is shown on the map by estimating the temperature 2 km below the surface. Estimates are calculated from drillholes with temperature measurements taken more than 250 m deep that, when extrapolated to 2 km depth, result in temperatures greater than 30°C. Outcropping granites, which are exposed at the surface, and undercover granites, which have been interpreted from gravity and magnetic surveys, are also shown on the map. The outcropping granites may contain very low levels of uranium, thorium and potassium which decay over millions of years, generating heat as a by-product but posing no health or environmental risk. When this heat becomes trapped under overlying rocks, it is a potential geothermal energy resource.
