Geothermal Energy. Geothermal energy is heat energy from the earth—Geo (earth) + thermal (heat). Geothermal resources are reservoirs of hot water that exist or are humanmade at varying temperatures and depths below the earth''s surface. Wells, ranging from a few feet to several miles deep, can be drilled into underground reservoirs to tap ...

Geothermal resources can be broadly grouped into shallow and deep geothermal. Shallow geothermal energy is the low-grade heat (10 to 25°C) that is stored in the shallow subsurface at depths of up to 500 m. It requires the use of ground-source heat pumps and can be used in most parts of the UK for the heating of buildings.
