The following page lists all power stations in Iceland . [1] Nearly all of Iceland's electricity (>99%) is generated from renewables (mainly hydroelectric dams and geothermal). [2] The islands of Grimsey and Flatey rely on diesel as they are not connected to the grid. [3]
Over 80% of electricity in Iceland is generated in hydroelectric power stations. The hydroelectric power stations, historically all run by Landsvirkjun, are central to the existence of Iceland as an industrialized country.
The largest power station by far is Kárahnjúkar Hydropower Plant (690 MW), which generates electricity in the area north of Vatnajökull for the production of aluminum.
Iceland uses geothermal energy for heating as well as electricity generation.

Geothermal power in Iceland refers to the use of geothermal energy in Iceland for electricity generation.
The British Columbia Hydro and Power Authority, operating as BC Hydro, is a Canadian electric utility in the province of British Columbia. It is the main electricity distributor, serving more than 4 million customers in most areas, with the exception of the City of New Westminster, where the city runs its own electrical department and portions of the West Kootenay, Okanagan, the Boundary Country and Similkameen regions, where FortisBC, a subsidiary of Fortis Inc. directly provides electric service to 213,000 customers and supplies municipally owned utilities in the same area. As a provincial Crown corporation, BC Hydro reports to the BC Ministry of Energy, Mines and Low Carbon Innovation, and is regulated by the British Columbia Utilities Commission (BCUC). Its mandate is to generate, purchase, distribute and sell electricity.
Kárahnjúkar Hydropower Plant, officially called Fljótsdalur Power Station is a hydroelectric power plant in Fljótsdalshérað municipality in eastern Iceland, designed to produce 4,600 gigawatt-hours (17,000 TJ) annually for Alcoa's Fjarðaál aluminum smelter 75 kilometres (47 mi) to the east in Reyðarfjörður. With the installed capacity of 690 megawatts (930,000 hp), the plant is the largest power plant in Iceland. The project, named after the nearby Kárahnjúkar mountains, involves damming the rivers Jökulsá á Dal and Jökulsá í Fljótsdal with five dams, creating three reservoirs. Water from the reservoirs is diverted through 73 kilometres (45 mi) of underground water tunnels and down a 420-metre (1,380 ft) vertical penstock towards a single underground power station. The smelter became fully operational in 2008 and the hydropower project was completed in 2009.
Iceland is a world leader in renewable energy. 100% of Iceland's electricity grid is produced from renewable resources. In terms of total energy supply, 85% of the total primary energy supply in Iceland is derived from domestically produced renewable energy sources. Geothermal energy provided about 65% of primary energy in 2016, the share of hydropower was 20%, and the share of fossil fuels was 15%.
According to the International Hydropower Association, Canada is the fourth largest producer of hydroelectricity in the world in 2021 after the United States, Brazil, and China. In 2019, Canada produced 632.2 TWh of electricity with 60% of energy coming from Hydroelectric and Tidal Energy Sources).
Kenya Electricity Generating Company PLC abbreviated to KenGen, is a government enterprise in the Republic of Kenya charged with the production of electricity for the country. KenGen is the largest electric power producer in Kenya, generating over 60% of the electricity consumed in the country.
Geothermal power is very cost-effective in the Great Rift Valley of Kenya, East Africa. As of 2023, Kenya has 891.8 MW of installed geothermal capacity. Kenya was the first African country to build geothermal energy sources. The Kenya Electricity Generating Company, which is 74% state-owned, has built several plants to exploit the Olkaria geothermal resource; Olkaria I, Olkaria II, Olkaria IV, Olkaria V, and Wellhead generation plants, with a third private plant Olkaria III. Additionally, a pilot wellhead plant of 2.5 MW has been commissioned at Eburru and two small scale plants have been built by the Oserian Development Company to power their rose farm facilities with a total of 4 MW.

Renewable energy in Russia mainly consists of hydroelectric energy. Russia is rich not only in oil, gas and coal, but also in wind, hydro, geothermal, biomass and solar energy – the resources of renewable energy. Practically all regions have at least one or two forms of renewable energy that are commercially exploitable, while some regions are rich in all forms of renewable energy resources. However, fossil fuels dominate Russia’s current energy mix, while its abundant and diverse renewable energy resources play little role.
The electricity sector in Iceland is 99.98% reliant on renewable energy: hydro power, geothermal energy and wind energy.
Renewable energy in Taiwan contributed to 8.7% of national electricity generation as of end of 2013. The total installed capacity of renewable energy in Taiwan by the end of 2013 was 3.76 GW.
Renewables supply a quarter of energy in Turkey, including heat and electricity. Some houses have rooftop solar water heating, and hot water from underground warms many spas and greenhouses. In parts of the west hot rocks are shallow enough to generate electricity as well as heat. Wind turbines, also mainly near western cities and industry, generate a tenth of Turkey’s electricity. Hydropower, mostly from dams in the east, is the only modern renewable energy which is fully exploited. Hydropower averages about a fifth of the country's electricity, but much less in drought years. Apart from wind and hydro, other renewables; such as geothermal, solar and biogas; together generated almost a tenth of Turkey’s electricity in 2022. Türkiye has ranked 5th in Europe and 12th in the world in terms of installed capacity in renewable energy. The share of renewables in Türkiye’s installed power reached to 54% at the end of 2022.
Hydroelectricity is currently China's largest renewable energy source and the second overall after coal. According to the International Hydropower Association, China is the worlds largest producer of hydroelectricity as of 2021. China's installed hydroelectric capacity in 2021 was 390.9 GW, including 36.4 GW of pumped storage hydroelectricity capacity, up from 233 GW in 2011. That year, hydropower generated 1,300 TWh of power, an increase of 68 TWh over 2018 when hydropower generated 1,232 TWh of power, accounting for roughly 18% of China's total electricity generation.
