The Wairakei Energy Station is a geothermal power station close to the Wairakei Geothermal Field in New Zealand. Wairakei lies in the Taupo Volcanic Zone.
The International Geothermal Association (IGA) reports that geothermal power plants produce additional than ten,000 megawatts of power in 24 countries worldwide. And while the US is the largest producer of geothermal power, generating around 3100 MW, it represents only .three% of total US energy production. Combined with the US Division of the Interior estimates that set the extended term prospective for domestic geothermal power generation at around 35,000 MW, the future of geothermal is very bright indeed.
Creating electricity with standard steam turbines requires working fluids at temperatures of at least 150 °C. This is only attainable with higher temperature geothermal sources of steam or superheated water which can be flashed to steam. The diagram below shows some of the achievable variants when high temperature water or steam is readily available.
Shere covers renewable energies fairly comprehensively, with chapters on biofuel, solar power, wind energy, geothermal energy, and several types of hydropower (from today’s cutting-edge machines to extract power from currents, waves or tides to the intrigues surrounding the birth of industrial electrical energy in North America as George Westinghouse, Thomas Edison and Nicola Tesla (amongst other folks) jockeyed for position.) It’s engaging, vivid, and easy to read.
There is, even so, a lot to like about geothermal energy. It is reasonably clean leaves behind tiny in the way of waste does not endure the vagaries of the weather or the inevitability of sunset makes the tiniest of footprints on the land and is fairly properly inexhaustible. Above all, it is additional or significantly less free of charge for the taking. However, lacking the political clout of wind and solar energy, geothermal electricity has in no way received the consideration it deserves.
