However, only 5,617 GWh p.a. were being generated in 1998. Iceland is richer in hot springs and high-temperature activity than any other country in the world. High-temperature activity is limited to certain fields. They are characterized by steam vents, mud pools, and precipitation of sulfur. No one knows exactly how much geothermal power is available in Iceland.
Power is therefore among the most important resources in Iceland.
Climate Iceland has a relatively coastal climate. Usually the weather is very changeable. The mild climate stems from the Gulf Stream and attendant warm ocean currents from the Gulf of Mexico. The weather is also affected by the East Greenland polar current curving southeastwards round the north and east coasts. For two to three months in summer there is continuous daylight in Iceland, and early spring and late autumn enjoy long twilight.
