What is Geothermal Energy?


there is a hydropower plant

Geothermal energy is an energy type obtained from the steam by artificial ways and the depths of the earth. Geothermal energy definition is a power generated from the internal temperature of the world.

Word of the geothermal means ‘’geo = earth and thermal = heat. Therefore, geothermal means the earth’s heat energy.

Use Area of the Geothermal Energy

There are many use area of geothermal energy. Besides, geothermal energy also provides many possibilities.

  • Waters and Mineral Waters Minerals
  • We use the energy in hot springs, hot water plants and greenhouses.
  • Engineers utilize as heat insulation in buildings or many workplaces.
  • Producers use geothermal energy in aquaculture.
  • We use this energy as process heat system.
  • Also, it provides the use of energy production.

How is Geothermal Energy Generate?


Have you ever wonder how does geothermal energy work? Geothermal energy to generate geothermal electricity from geothermal sources, tribunes drill at a depth of 1.6 kilometres or more. The renewable energy creates kinaesthetic energy by extracting hot water resources from the underground. Afterwards, the water vapour activates produced by panels. Therefore, power is generated by the generation of kinaesthetic energy into electrical energy.


Advantages of the Geothermal Energy


As geothermal energy pros, we can say;

  • The yield of green renewable energy is high, and we can obtain directly. Therefore, the cost is quite low. If it is correctly renewable, then it provides a reliable power supply.
  • Energy cost of the geothermal is lower than hydroelectric energy. By the way, hydroelectric power has the lowest energy-generating price.
  • The energy type doesn’t harm the environment in any way.
  • Thanks to geothermal energy, we minimize the usage of fossil fuels.
  • There is a risk of explosion in natural gas, but there is no risk in geothermal energy.
  • The energy-generating areas produce only one-sixth of the carbon dioxide produced by a clean natural gas-fired power plant.

Disadvantages of the Geothermal Energy


There are also a lot of geothermal energy cons;

  • Deteriorating of the water quality.
  • Releasing of hydrogen sulfide that gas smells of rotten eggs at low concentrations.
  • It causes the removal of some geothermal fluids which may contain low-level toxic materials.
  • It causes heart and lung diseases.
  • Causing the acid rains

The Renewable Geothermal Examples

  • United State: Since 1890, geo-energy has been using in Idaho, Boise
  • Iceland: Since 1890 in Reykjavik
