Countries With a Similar Electricity Mix
Ember annual, 2025Czechia's closest match is Bulgaria, 80.0% the same, and the match goes both ways, so they are grid twins.
- Bulgaria 80.0% the same · grid twin Bulgaria generates 12.6 points less coal than Czechia
- Ukraine 77.1% the same Ukraine generates 14.3 points less coal than Czechia
- South Korea 76.4% the same South Korea generates 22.6 points more gas than Czechia
- Slovenia 69.5% the same Slovenia generates 25.2 points more hydro than Czechia
- Hungary 62.2% the same Hungary generates 31.9 points less coal than Czechia
How close: the share of generation that would have to change fuel for one mix to match the other (half the sum of the fuel share differences); 100% minus that is "the same". Grids under 1 TWh are skipped. Grid twins: the 25 closest pairs and every country's nearest match
