Electricity generated by wind farms over the year, in terawatt-hours. As with solar, the absolute figure and the share diverge: countries with large power systems come first on generation, small ones with favorable geography on share. Wind generation swings from year to year with how windy it was, and swings of ten percent with an unchanged fleet of turbines are normal here — that is a property of the resource, not a data error.
Important: Generation, not capacity: the capacity factor of onshore wind is about 30%, and higher offshore. The series starts in 2000.
