Volcanic sources of the free element are also widespread they have been of great economic importance until thi.s century but are now little used. They occur throughout the mountain ranges bordering the Pacific Ocean, and also in Iceland and the Mediterranean region, notably in T irkey, Italy and formerly also in Sicily and Spain.

A related aspect of geothermal energy is the thermal gradient, which is the increase of temperature with depth below Earth s surface. The average thermal gradient is about 30°C (54°F) per kilometer, but it can be much higher at specific locations—for instance, in Iceland, where the increase is greater than 100°C (180°F) per kilometer in places.

Direct geothermal energy is used for space heating of homes, greenhouses, livestock barns, and fish-farm ponds. As well, it is employed as a heat source in some industrial processes, such as paper production in New Zealand and diying diatomite in Iceland. Since the industrial applications usually require high-... 

One of the countries that makes extensive use of direct geothermal heat is Iceland. This might seem surprising for a country with ice as part of its name.
