Geothermal energy can be used for space heating (and cooling), district heating, heating of swimming pools, etc., and to generate electricity if the resource is hot enough.
In Ireland, use of geothermal energy is dominated by ground source heat energy together with heat pump technologies for heating houses, hotels, nursing homes and other business premises, public buildings and swimming pools, and horticulture amongst other uses. Cooling systems using the subsurface are used mainly in industry and offices.
