What is geothermal energy derived from?

Geothermal energy is derived from the heat that is naturally present in the Earth's crust. This heat is a result of the radioactive decay of minerals and the residual heat from the planet's formation. It can be harnessed by accessing hot water and steam that are found beneath the Earth's surface, typically in areas with volcanic activity or tectonic movement. This heat can then be used for various applications, such as generating electricity or providing direct heating for residential and industrial use. The sustainable nature of geothermal energy, as it relies on the Earth's internal heat, makes it a valuable renewable energy source.
