Geothermal energy is derived from heat produced by the decay of radioactive elements within the Earth’s molten core, where temperatures reach 6000°C around 6000 km below the ground. This heat naturally dissipates upwards towards the earth’s surface.

Geothermal energy is usually associated with countries that have active volcanoes, for example Iceland, where, geothermal energy provides two thirds of the country’s primary energy, mainly used for heating homes, and 25% of its electricity generation.

While the UK does not possess any active volcanoes it does have several geological features at depths of between 2-4 km that are potential geothermal targets, albeit with lower temperatures of around 60-80°C.
