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.
