Luxembourg
LUXWind overtook bioenergy on Luxembourg's grid in 2023.
Today wind supplies 31% and bioenergy 27%.
What this grid depends on
Three measures that say more about a country than how much power it makes. Open “what this means” on any of them if the term is new.
Among the cleanest electricity anywhere.
What this means
How much planet-warming gas is released to make one unit of electricity. Two countries can generate exactly the same amount and one of them be ten times dirtier doing it. Lower is better.
Luxembourg depends heavily on its neighbours for power.
What this means
The share of the electricity used here that was generated abroad and carried in over high-voltage lines. The higher it climbs, the more this country relies on a neighbour to keep its lights on.
Most of the fuel behind this grid is bought from abroad.
What this means
How much of what this grid runs on the country can supply itself. Sun, wind and water count fully, because nobody can cut them off; coal, gas and oil only as far as the country digs them up. A high score is not the same as a good grid: mining your own coal scores well, importing uranium scores badly.
Also true of Luxembourg
Luxembourg brings in 77% of the electricity it uses.
Its own power stations cover the rest.
Luxembourg is third in the world for solar.
Solar supplies 31% of its electricity.
Luxembourg's electricity is cleaner than the world average.
123 grams of CO2e a kilowatt-hour against a world figure of 458 — 73% below.

Figures are for 2025, the most recent year reported for Luxembourg. Generation shares are a percentage of electricity generated, not of energy used. How this is calculated.
