#102 Geothermal Energy

We discussed with Riccardo Clementi from Enel Group, and we also had a chance to visit Museo della Geotermia di Larderello where Giorgio Simoni shared impressive stories about the history and technology of geothermal energy utilization. What is geothermal power? How is it produced? Geothermal power plants use high-temperature (150 °C to 370 °C) hydrothermal resources, either dry steam or hot water, that power a turbine in order to generate electricity. Some geothermal wells are as much as 3 km deep! Geothermal power is considered to be a sustainable, renewable source of energy because the heat extraction is small compared to the heat content of the Earth. The story of geothermal power began 118 years ago when Prince Piero Ginori Conti. Tested the first geothermal power generator in Larderello and managed to lit four light bulbs. ???? Later, in 1911, the world’s first commercial geothermal power station was built there. And today, 33% of Tuscany’s and 3% of Italy’s electricity is produced with geothermal power!
