Types of Geothermal Energy Use
Geothermal energy usage areas are examined in two main groups:

Direct Use
- Central heating systems (city heating, greenhouse heating, residential heating)
- Thermal tourism (thermal springs, spa centers, health cure centers)
- Drying agricultural products
- Hot water fish farming
- Snow and ice melting (on roads and airports)
- Mineral and mineral production
Indirect Use
- Electrical energy production
The areas of use of geothermal energy vary depending on the temperature of the source. Today, geothermal resources are used worldwide for thermal tourism purposes. Thermal springs, spa centers, bath and swimming facilities are among the most common applications. In addition, geothermal energy is used to clear roads and airports of snow and ice in countries such as the USA, Switzerland, Japan, Iceland and Argentina. Geothermal resources are also used in agricultural production and industrial areas.
