Greece
GRCSolar overtook wind on Greece's grid in 2025.
Today solar supplies 22% and wind 20%.
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.
Cleaner than 6 in 10 grids worldwide.
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.
Greece generates a surplus and sells it on.
What this means
The share of what this country generates that is sold abroad rather than used at home. A country can only export if it produces more than it needs, which usually means plentiful hydro, nuclear or wind.
More of its fuel is bought in than produced at home.
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 Greece
Greece is among the world's biggest wind and solar producers and still burns fossil fuels for most of its power.
43% of its electricity is wind and solar; 50% is still fossil. Both are true at once, and that tension is the whole story of the transition.
Gas overtook coal on Greece's grid in 2019.
Today gas supplies 38% and coal 5%.
Greece's electricity is cleaner than the world average.
315 grams of CO2e a kilowatt-hour against a world figure of 458 — 31% below.
Greece’s neighbours
Figures are for 2025, the most recent year reported for Greece. Generation shares are a percentage of electricity generated, not of energy used. How this is calculated.
