. . .  geothermal energy has gradually replaced imported fossil fuel, and today over 98% of houses in Reykjavík and neighbourhood enjoy geothermal heating. It has been estimated that in 1960 the annual emission of greenhouse gases due to space heating in the Reykjavík area was about 270,000 tonnes. To day this figure is about 12,000 tonnes, all natural emission from the Nesjavellir high-temperature area (Gíslason 2000). This is one of the main benefits of utilization of geothermal energy for space heating. . . .

. . .  environment. Geothermal heat is one of Iceland’s greatest natural resources. The capital city has enjoyed this inexpensive and reliable power source for more than 70 years. This paper deals mainly with the use of geothermal energy for space heating and electrical production. Geothermal activity in Iceland Iceland lies on the Mid-Atlantic Ridge, a spreading ridge and fracture zone forming an underwater mountain range and rifts splitting the earth's crust under the Atlantic Ocean from North to South. . . .
