What Is Geothermal Energy?
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...
