The UK currently has no large-scale geothermal power plants in operation, though a 3-megawatt (MW) demonstration project is planned for Cornwall, a region in southwestern England.
Geothermal energy could realistically provide as much as 10% of the country’s total energy needs, according to a recent report published by Geothermal Research Programme.
Cameron says he will increase the number of Renewable Obligation Certificates (ROCs) that geothermal plants are eligible to receive, as the government has recently done for offshore wind.
