Countries With a Similar Electricity Mix
Ember annual, 2025Cambodia's closest match is Bosnia and Herzegovina, 90.9% the same, and the match goes both ways, so they are grid twins.
- Bosnia and Herzegovina 90.9% the same · grid twin Bosnia and Herzegovina generates 6.6 points less solar than Cambodia
- Vietnam 88.5% the same Vietnam generates 8.8 points less coal than Cambodia
- Serbia 80.3% the same Serbia generates 9.7 points less solar than Cambodia
- China 79.9% the same China generates 16.7 points less hydro than Cambodia
- India 75.0% the same India generates 21.3 points less hydro than Cambodia
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
