Geothermal and hydroelectric power plants
Iceland has successfully harnessed its abundant geothermal energy, with geothermal power plants providing about 65% of the country's primary energy in 2016. Geothermal energy has been used in Iceland since the Viking Age, initially for washing, bathing, and heating homes, greenhouses, and swimming pools. Iceland's territory is some of the most geologically active on Earth, with the country straddling the Mid-Atlantic Ridge and lying over a volcanic hotspot. This results in pronounced volcanism and geothermal activity, with over 20 high-temperature steam fields that reach at least 150 °C, and many exceeding 250 °C. These steam fields are used for heating, and “cold” areas away from the steam fields are used to produce warm water for space heating. Geothermal energy is also used for electricity generation, with Iceland's active geology providing natural conditions that are especially suitable for harnessing geothermal power. The government has supported the growth of geothermal power, with Iceland's installed geothermal power production capacity reaching 799 megawatts (MW) as of 2020.
Iceland also has a large number of hydroelectric power plants, which provided about 20% of the country's primary energy in 2016. In 2005, Landsvirkjun, the National Power Company and main supplier of electricity in Iceland, produced 7,143 GWh of electricity, of which 93% was generated through hydroelectric power plants. Iceland has a mountainous landscape with many rivers, especially glacial ones, that fall from high elevations, providing significant changes in elevation over small distances. This makes the country ideal for hydroelectric power generation, and in 2009, Iceland built its biggest hydroelectric project to date, the Kárahnjúkar Hydropower Plant, a 690 MW hydroelectric plant. This project was opposed by environmentalists as it provides energy for aluminium smelting, a power-intensive industry.
Together, geothermal and hydroelectric power plants supply about 85% of Iceland's energy needs, with nearly 100% of its electricity generated by renewable energy sources. Iceland is the world's largest green energy producer per capita, and its success in implementing renewable energy has made it a popular tourist destination, with visitors keen to learn about its innovative clean-energy solutions.
