Geothermal energy is the heat produced by decay of radioactive isotopes deep within the Earth. The temperature at the centre of the Earth is thought to be around 5,000°C, with the temperature reducing toward the surface. It is estimated that 99.9% of the planet is above 100°C. Geothermal energy is considered a renewable source as the amount available is much greater than the demand. This Catalyst article looks at how geothermal energy is derived from hot rocks below the Earth's surface and can be used for heating or to generate electricity.
