When most are asked to think about geothermal power, their minds will most likely turn to Iceland and with good reason. The country sits across one of the earth’s great tectonic plate boundaries and, as such, 25 per cent of its electricity demand is supplied by this near limitless geothermal resource. But geothermal power production is not limited to Iceland. Pioneering deep geothermal projects in France, Germany and across Europe have demonstrated its potential as a viable renewable energy source comparable to wind, solar and tidal power. Better yet, it can be extracted regardless of the weather, the power as it were, turned off and on to meet demand, like a tap. On 6 November, drilling work began at the United Downs Industrial Estate in St Day in Cornwall, on the UK’s first ever deep geothermal power plant. We anticipate it is only the first step towards making geothermal a viable alternative power source in the UK and of a nascent British industry.
