The Earth gets hotter by 2.5C to 3.5C with each 100m depth. It’s what makes geothermal energy possible, anywhere. In the UK geothermal could meet the nation’s heat demands for at least 100 years, say Jon Gluyas, Andrew Crossland and Charlotte Adams of the Durham Energy Institute. Properly managed it could last indefinitely. Given that heat does not travel well, geothermal must be developed locally. Fortunately, accessible heat lies beneath or … [Read more...]
