Countries With a Similar Electricity Mix
Ember annual, 2025Belgium's closest match is Spain, 78.7% the same, and the match goes both ways, so they are grid twins.
- Spain 78.7% the same · grid twin Spain generates 14.7 points less nuclear than Belgium
- Hungary 76.2% the same Hungary generates 17.2 points less wind than Belgium
- United Kingdom 68.2% the same The United Kingdom generates 21.1 points less nuclear than Belgium
- Netherlands 65.9% the same The Netherlands generates 30.6 points less nuclear than Belgium
- Greece 62.7% the same Greece generates 33.5 points less nuclear than Belgium
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
