The geothermal energy is a primary and alternative energy. This renewable energy tuses the heat of the subsoil to obtain hot water in an ecological way. Sweden was the first European country to use geothermal energy in 1979. In Iceland's famous geysers you can see gigantic columns of fiery water rising to 60 meters! There are three types of geothermal reservoirs:
- Hot water, which is normally used for thermal baths.
- Dry, which use them to heat water by the stones and minerals that are underground.
- And geysers, that water is propelled from the ground at great speed to form giant water columns and hot steam.
Advantage:
- Being a renewable energy, it decreases the energy dependence of nonrenewable resources
- The wastes it produces do not pollute as much as other fuels, such as coal or oil.
- Does not generate outside noise
- These resources are practically inexhaustible.
- No felling of trees for the construction of the geothermal plant due to the location of where it is.
Disadvantages:
- In the dry fields sometimes earthquakes occur as a consequence of the sudden cooling of the hot stones when it is in contact with the water to warm it up
- Sometimes the emission of hydrogen sulfide in the geysers occurs at such large amounts that it can be lethal.
- The landscape deteriorates
- Thermal contamination
- Can not be transported
- Only available in certain places.
