Countries With a Similar Electricity Mix
Ember annual, 2025Spain's closest match is Belgium, 78.7% the same, and the match goes both ways, so they are grid twins.
- Belgium 78.7% the same · grid twin Belgium generates 14.7 points more nuclear than Spain
- Pakistan 72.8% the same Pakistan generates 18.2 points less wind than Spain
- Greece 72.7% the same Greece generates 18.8 points less nuclear than Spain
- Netherlands 72.1% the same The Netherlands generates 15.8 points less nuclear than Spain
- Romania 70.6% the same Romania generates 14.8 points more coal than Spain
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
