Geothermal Power: Electricity From Earth’s Untapped Potential (Earth Techling)
Along with hydropower, geothermal power is an old form of renewable energy. The first geothermal power plant developed to generate electricity dates back to 1904, in Italy — though geothermal energy more broadly has been utilized in one way or another even longer. Though firmly established geothermal power doesn’t get the press, nor public mention, nor investment, as newer, flashier forms of renewable energy, such as solar power, wind power, or biofuels.
Nevertheless, geothermal power can, in the right places, be a very important part of a future low-carbon energy mix. Let’s take a look at how geothermal power is tapped to produce electricity, how much is being generated, and how much possibly could be generated with changes in technology currently being explored.
