What is geothermal energy primarily derived from?

Geothermal energy is primarily derived from the heat generated within the Earth's crust. This natural heat originates from several sources, including the decay of radioactive isotopes in the Earth's interior and the residual heat from the planet's formation. This subterranean heat can be harnessed for various applications, such as electricity generation and direct heating, making it a sustainable and renewable energy source.

The process involves tapping into geothermal reservoirs, where heat is trapped in rocks and fluids beneath the Earth's surface. By utilizing technologies such as geothermal power plants, we can convert this thermal energy into usable power. The efficiency and low emissions associated with geothermal energy make it a valuable alternative to fossil fuels in the quest for cleaner energy solutions.
