| Energy in Iceland | |
Iceland is the only country in Western Europe that still has large resources of competitively priced hydroelectric power and geothermal energy remaining to be harnessed. Although electricity consumption per capita in Iceland is second to none in the world, at about 28,200 kWh per person, only a fraction of the country’s energy potential has been tapped. Total economically viable electric power potential is now estimated at 50,000 GWh/year. About 8,490 GWh/year of this power had been harnessed in 2003, i.e. only about 17% of the total electrical energy potential.
Economically harness able electricity from hydro resources is estimated at about 30,000 GWh per year. The first hydropower plant was constructed in 1904, generating 9kW. In 2003, the total installed hydropower is 1,155 MW and the hydropower production was around 7,100 GWh. The largest single hydropower plant has a production power capacity of 270 MW.
Icelanders are world leaders in the use of geothermal energy for domestic and industrial purposes. About 87% of the population enjoy central heating by geothermal energy at a price that is generally less than half of the comparable cost of oil or electric heating, thus contributing to making Iceland one of the cleanest environments in Europe. Geothermal steam has been used directly for a number of industrial processing applications in Iceland for decades now, and has also been developed for electricity generation on a small but growing scale. In 2003 the total installed geothermal electric power was 200 MW and the production around 1,420 GWh.
Both hydro and geothermal power are sustainable and supremely environment-friendly – “green” resources which are free from the atmospheric emissions of fossil fuels and the potential hazards of radioactive power sources. In the case of aluminium production, using electricity generated by hydropower instead of coal will typically cut total emissions of CO2 by about 90% per ton of production. A recent venture backed by Daimler-Chrysler, Norsk Hydro and Shell has located one of the world’s first pilot projects for developing infrastructure of a hydrogen-driven transport system in Iceland, using hydropower to make an emission-free petrol substitute, sometimes called “the energy source of the future”.
