By Thomas Braun, EoS-Earth & Space News, AGU. For GSS Energy Use chapter 4. Excerpt: After nearly a century of generating geothermal power, energy extraction in Tuscany might be entering a new phase. For the past 25 years, production has been accompanied by a small but steady increase in seismicity near geothermal wells. Tuscan communities are beginning to wonder: Does generating power trigger this seismicity? A new project seeks answers. ...Because hot areas are so close to the surface, communities dating back to Roman times harnessed the hot springs as therapeutic baths. In 1904, gentleman scientist Prince Piero Ginori Conti tested the world’s first geothermal power generator—successfully lighting five light bulbs—in Tuscany’s Larderello district. In 1911, Larderello became home to the world’s first commercial geothermal power plant. ...until 1958, Tuscany was the only area in the world producing geothermal energy. More plants were built in volcanic areas of Tuscany and Latium in the 1960s, including several near Mount Amiata and Latera, and production across the Tuscan geothermal fields has continuously increased ever since. Today, geothermal energy from Tuscany accounts for 1.5% and 23.5% of energy produced in Italy and Tuscany, respectively, and 8% of geothermal energy produced around the world....  https://eos.org/project-updates/does-geothermal-exploitation-trigger-earthquakes-in-tuscany
