Czechia
CZENuclear overtook coal on the Czechia's grid in 2023.
Today nuclear supplies 42% and coal 35%.
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.
Czechia 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.

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