The Geothermal PowerPlant

Informations about generation of electricity in a geothermal Power-plant

With terrestrial heat the geothermal Power-plant is producing electricity. This kind of power generation is usable on a longterm future.

Function

Within a geotherm Power-plant, as with a steam power plant, water vapour or steam of another evaporatable medium is used, in order to propel a turbine. The water is led by a cooling tower into a deep underground container, in which it evaporates by the warmth of the interior of the earth. The water vapour produced now rises up to the earth surface and propels a turbine, which now under assistance of a generator produces the electricity.
Afterwards the water vapour goes back into the cooling tower and becomes water again.

pro- and Cons

The probably most important advantage of this kind of the generation of electricity is in the terrestrial heat. If it would be used meaningfully and on a broad area, then the world-wide current consumption could be covered for at least over 100,000 years.
Additionally the Geotherm is extremely environmental friendly, specially in the aspect of the CO2 emmission. The disadvantage is based in the fact that underground tensions could often be released by the building of geothermal Power-plants and can release earthquakes.
