Geothermal energy is heat within the sub-surface of the earth. Water and/or steam carry geothermal energy to the surface of the earth.

Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity. There are different geothermal technologies with distinct levels of maturity.

Technology for direct uses like district heating, geothermal heat pumps, greenhouses, and for other applications are widely used and considered mature.

Technology for electricity generation from hydrothermal reservoirs with naturally high permeability is more than 100 years old and reliable.

Despite the staggering amount of energy is trapped beneath our feet, only 15 GWe of energy is currently produced commercially from Geothermal sources today – equivalent to the daily demand of Wales.
