hot rocks

Geo-thermal energy could be a triple win for the world: clean, reliable, locally-produced power. Iceland's energy needs are  presently met by 40% geotherm but you need not be a volcanic island like Iceland to access the geotherm potential.

Recently, scientists have stated that 40% of Glasgow’s heating needs could come from geothermal power located in local abandoned coal mine shafts. There are many such mines throughout the country, and some of them are located deep enough below ground level that they have accumulated water. This water is warm enough it can be pumped up to heat buildings and homes.

Glenalmond Street in Shettleston, uses a combination of solar and geothermal energy to heat 16 houses. Water in a coal mine 100 metres (328 ft) below ground level is heated by geothermal energy and maintained at a temperature of about 12 °C (54 °F) throughout the year. The warmed water is raised and passed through a heat pump, boosting the temperature to 55 °C (131 °F), and is then distributed to the houses providing heating to radiators.
