geotermískt

Geotermískt refers to heat originating from within the Earth. This internal heat is generated by the decay of radioactive isotopes and residual heat from the planet's formation. Geothermal energy is the thermal energy generated and stored within the Earth. This heat can be harnessed for various applications, including electricity generation and direct heating.

The Earth's interior is extremely hot, with temperatures increasing with depth. In certain regions, this heat comes closer to the surface, often associated with volcanic activity and tectonic plate boundaries. Geothermal resources can be categorized into different types, such as hydrothermal, hot dry rock, and geopressured resources, each with unique characteristics and extraction methods.

Hydrothermal systems are the most common type used for energy production. They involve the presence of hot water and steam reservoirs beneath the Earth's surface. Geothermal power plants utilize this hot fluid to drive turbines and generate electricity. Direct use applications involve using geothermal heat directly for purposes like heating buildings, greenhouses, and aquaculture. Geothermal heat pumps also utilize the stable temperature of the Earth's shallow crust for heating and cooling. The utilization of geothermal energy is considered a renewable energy source as the Earth's internal heat is continuously replenished.
