Geothermal-powered nation

摘要

The sound of drilling pierces the air in the typically tranquil town of Penzance, Cornwall—earlier this year, work began on a geothermal well that will tap water naturally warmed underground to supply the town's Jubilee swimming pool. Drilling a 1.4-km-deep well to heat part of a pool may seem indulgent, but the project raises the question of whether geothermal energy could realistically form a significant component of the UK's low-carbon future.
