Geothermal Energy, the Earth’s Heat

The Earth's heat stems from the planet's formation and its natural radioactivity. © THINKSTOCK

Extreme temperatures deep within the Earth heat the rocks of the crust, along with the water and steam they contain. Geothermal energy refers to our use of this energy source, recovered to heat buildings or produce electricity.

Low-temperature geothermalDescribes the technology used to tap subsurface heat to produce energy... energy is used to supply heating for homes, apartment and office buildings, public facilities and farms. Medium- and high-temperature geothermal energy, above 90°C, is used to generate powerIn physics, power is the amount of energy supplied by a system per unit time. In simpler terms, power can be viewed as energy output...
