A **geothermal facility** is a power plant or heating system that uses heat from within the Earth to generate electricity or provide direct heating. These facilities tap into underground reservoirs of hot water and steam, which can be naturally occurring or enhanced by injecting water into hot rock formations.
There are three main types of geothermal power plants:
1. **Dry Steam Plants** – Use steam directly from underground to turn turbines.
2. **Flash Steam Plants** – Take high-pressure hot water from the ground, convert it to steam, then use the steam to drive turbines.
3. **Binary Cycle Plants** – Use moderately hot water to heat a secondary fluid with a lower boiling point, which then vaporizes and turns a turbine.
In addition to power generation, geothermal systems are also used in **district heating**, **greenhouse heating**, and **geothermal heat pumps** for buildings.
