Geothermal

In the UK, there is a resource of geothermal energy at shallow depths which can be exploited with ground source heat pumps (GSHPs).

With a temperature of nearly 11,000°F, the Earth's core is hotter than the surface of the sun and humans have found a way to safely harness a small portion of that heat energy to generate power. It's called geothermal energy.

The term ‘geothermal energy’ refers to any heat derived from the ground, from depths of a few metres to multiple kilometres beneath the Earth’s surface.

Geothermal has the potential to heat millions of homes in the UK. Despite that, this source of energy is too little used.

Energy firm Ecotricity has signed a ten-year deal for electricity which will be produced by a British geothermal power plant, representing another step forward for the country’s fledgling industry. 

The UK's first lido to be heated by geothermal energy has opened.  The Jubilee Pool in Penzance, Cornwall uses underground heat to keep the sea water pool at 35°C.  Engineers behind the project said while the pool is the first lido in the UK to be geothermally heated, "the Romans beat us to it by 2000 years in Bath".
