...Diavolo (Devil's Valley) for the boiling liquid that bubbled out of the ground. But this swath of central Tuscany is not bathing in nostalgia. It continues to produce 10% of the world's geothermal power - about 4.8 billion kW-h per year - while one-quarter of the entire Tuscan region's electricity comes from local steam energy production, feeding around a million households. Guido Cappetti, who heads the geothermal division for Enel, Italy's giant energy provider, puts it plainly: "Larderello is like a permanently unexploded volcano." The natural - and unique - abundance of hot liquids at relatively shallow depths...
...This has led over the past two decades to Enel's development of innovative deep exploration techniques that allowed it to drill down past the hotter (up to 400C) subterranean layers that exist at 3,000 to 4,000 m - twice as deep as earlier explorations. The Tuscan approach of looking deeper is now utilized elsewhere in the world during initial explorations, and will be applied when other shallow wells begin to dry up. Back at the drilling site, a team of geologists demonstrates the latest push to expand the search for new sources of steam. Borrowing from the most...
