Geothermal energy

Geothermal energy is the energy of geothermal waters extracted to the surface of the Earth. Its source – the hot interior of the globe – is inexhaustible.

In order to extract geothermal waters, wells are drilled to the surface of the ground to the depth of these waters.
At a distance from the borehole, a second borehole is made, where the geothermal water, when it receives heat from it, is forced back into the bed. Geothermal waters are usually strongly saline, which is the reason for particularly difficult operating conditions of heat exchangers and other elements of geothermal installations fittings. Geothermal energy is used in central heating systems as the basic source of thermal energy.
The second use of geothermal energy is the production of electricity, which is profitable only in the case of particularly hot sources.

Hot springs, so-called Geysers are a characteristic feature of the Icelandic landscape that uses them as a source of heating and hot water. This does not adversely affect the natural environment.

  • renewal and inexhaustibility
  • independence from weather conditions
  • full integration with the landscape
  • w niektórych lokalizacjach potencjał może być niewystarczający
  • s a side effect, harmful gases and minerals that are sometimes released into the atmosphere or surface and deep water can be treated
  • not everywhere where there is potential for using geothermal energy, such acquisition is possible
  • initial installation costs are high and require large financial outlays
  • the possibility of moving geothermal deposits
