The Earth generates heat which can be harnessed by drilling down below the surface to provide a renewable, and continuous source of energy to heat and power our homes – known as geothermal energy. At shallow depths the heat is enough to warm our homes and businesses. Granite is particularly ideal for this technology as it is very effective at holding and conducting the Earth's heat. He said geothermal power was "really important" for the UK because there are no price fluctuations like with gas. For the first time, we're tapping into "always-on" green power in the UK, providing a steady stream of clean, home-grown energy," said an Octopus spokesperson.
