geothermal heat
Underground thermal energy
Geothermal heat is thermal energy generated and stored within the Earth, originating from the planet's formation and ongoing radioactive decay in its core.
This heat can be harnessed for electricity generation or direct heating applications: The spa draws on geothermal heat from underground springs.
Geothermal energy is considered renewable since the Earth continuously produces heat.
