As my right hon. Friend will know, along with the Minister for Disabled People, Health and Work, my hon. Friend Sarah Newton, I have been a champion of the potential of geothermal energy in Cornwall. Although progress has been frustrating, we are very excited to be on the verge of seeing test drilling. Does my right hon. Friend agree that geothermal energy has the potential to play a significant role in the delivery of clean renewable energy in this country, and will she back its development in Cornwall?
