Geothermal Energy
Geothermal energy originates from the heat of the Earth’s interior. It is a stable and renewable energy source used for heating, cooling, and electricity production. Unlike solar and wind energy, geothermal energy is available 24 hours a day, year-round.
Geothermal and hydrogeothermal energy represent a unique renewable energy source whose key advantages lie in ease of use, technological simplicity, and relatively low implementation costs.
Applications of Geothermal Energy
Geothermal energy has a wide range of applications. The most important include:
District heating and cooling
Reduces heating costs, greenhouse gas emissions, and air pollution (by decreasing the use of fossil fuels whose combustion releases harmful gases and particulate matter)
Electricity generation
A stable and reliable energy source
Industrial processes
Food processing, drying facilities, and manufacturing
Health and spa tourism
Thermal spas and wellness centers
Agriculture
Greenhouses and crop drying systems
Examples of Geothermal Energy Use
There are numerous successful examples of geothermal energy utilization in Europe and worldwide:
Iceland
A national district heating network covering almost the entire population
Germany
Bavaria has developed geothermal power plants supplying both heat and electricity to local communities
Hungary
Geothermal waters used for greenhouses and spa tourism
France
The Paris Basin has a developed district heating network based on geothermal sources
China
The world’s largest single geothermal heating system is located in Tianjin
