Carbon dioxide emissions from the power sector per kilowatt-hour of generation. A single number into which the whole structure of generation folds: a coal plant gives about 820 grams per kilowatt-hour, a gas plant roughly 490, and nuclear, wind and solar single digits. The indicator therefore reads as a summary verdict on a power system and is especially useful for comparing countries with different generation mixes: one may have a lot of hydro and another nuclear, yet the result comes out close.
Important: Emissions from generating electricity are counted, without emissions from building the plants and extracting the fuel. Aggregates are weighted by generation and computed from 2000 onward.
