The heat at the centre of our planet could fulfil all of our energy needs. Find out how some are already utilising geothermal power.
- Geothermal power is obtained from heat within the planet's magma.
- Geothermal power can be used directly to provide heat and hot water for buildings.
- Geothermal power stations emit 2000 times less carbon dioxide than fossil fuel power plants.
- Geothermal power can only be accessed where the Earth's crust is thin or where tectonic plates meet.
Deep within the centre of the Earth lies a heat source 1000 degrees hotter than the surface of the Sun.
Melting temperature of Earth's core is 6,200°C
This heat is produced within the planet's magma, layers of hot and molten rock, as naturally radioactive materials, such as uranium and potassium, decay. ...
