How much electricity in Switzerland comes from renewables?
Renewable sources produced 67.8% of the electricity generated in Switzerland in 2025. The world average was 33.8% in 2025. That is up from 57.0% in 2000. That ranks Switzerland 49th of 210 countries and territories by renewable share.
Electricity mix by source
Hydro is the largest source of electricity in Switzerland, at 52.3% of generation, followed by nuclear at 29.9% and solar at 12.1%. Fossil fuels together supplied 2.3% and nuclear 29.9%.
Carbon intensity of electricity
Generating one kilowatt-hour of electricity in Switzerland emitted about 39 grams of CO₂ in 2025, 91% below the world average of 458 g. At that rate, a business using 10,000 kWh a year would be responsible for roughly 392 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.
