How much electricity in Iceland comes from renewables?
Renewable sources produced 100% of the electricity generated in Iceland in 2024. The world average was 33.8% in 2025. The share is about the same as in 2000, when it was 100%. That ranks Iceland 7th of 210 countries and territories by renewable share.
Electricity mix by source
Hydro is the largest source of electricity in Iceland, at 70.7% of generation, followed by other renewables at 29.2% and wind at 0.1%. Fossil fuels together supplied 0%.
Carbon intensity of electricity
Generating one kilowatt-hour of electricity in Iceland emitted about 28 grams of CO₂ in 2024, 94% below the world average of 458 g. At that rate, a business using 10,000 kWh a year would be responsible for roughly 278 kg of CO₂ from electricity.
This is an estimate based on the generation mix. For a formal carbon report, use the grid factor published by the national energy or environment agency. Our guide to emission factors explains the difference.

About the data. Shares are percentages of the electricity generated inside the country in a year. Renewables are hydro, wind, solar, bioenergy and other renewable sources. Low-carbon adds nuclear. The latest year differs between countries and is shown on each page. Carbon intensity is an estimate of the CO₂ emitted per kilowatt-hour generated, including emissions over the life of each power source.
