Countries ranked by low-carbon share of electricity

Low-carbon electricity combines all renewable sources with nuclear power, so everything that does not burn fossil fuels. It is the best single indicator of how decarbonised a power system is.

Countries can reach the top through very different routes: hydro (Norway, Paraguay), nuclear plus hydro (France, Sweden, Switzerland) or wind and solar (Denmark).

Ranking rule. Countries and territories that generate less than 1 TWh of electricity a year (mostly small islands) are left out, because one diesel generator or one solar farm can swing their shares by tens of points. Values older than 2020 are also excluded.
