Geothermal energy is a clean, natural, renewable and reliable source of energy which is used successfully in many countries. Typically, geothermal power plants have very low or zero emissions and even the very small plant envisaged at United Downs would reduce greenhouse gas emissions by more than 3,000 tonnes per year compared to conventional generation.
Geothermal power plants operate more than 90% of the time and are not dependent on favourable weather or daylight. Land use per MW is much lower than other renewables and, in fact, much lower than most energy sources.
In addition to generating electricity, geothermal plants produce lots of heat that can be used for a number of purposes.
