Geothermal History

By the end of the 19th century, Prince Piero Conti conceived the idea to harness the natural steam of the Larderello, Italy, geothermal field to produce electric energy. He started to develop technical experiments and tests in 1903, and a year later the first geothermal-electric energy was produced and used to light five lamps of 5-watts. In 1913 Conti put in commercial operation a power plant of 250 kilowatts (kW) fed by pure steam, and in 1916 two power units of 3.5 megawatts (MW) each. Geothermal power production was born.
