Electricity mix by source
Nuclear is the largest source of electricity in Finland, at 39.9% of generation, followed by wind at 27.4% and hydro at 15.1%. Fossil fuels together supplied 3.7% and nuclear 39.9%.
Carbon intensity of electricity
Generating one kilowatt-hour of electricity in Finland emitted about 57 grams of CO₂ in 2025, 87% below the world average of 458 g. At that rate, a business using 10,000 kWh a year would be responsible for roughly 575 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.
