Countries With a Similar Electricity Mix

Ember annual, 2025

Romania's closest match is Pakistan, 81.2% the same, and the match goes both ways, so they are grid twins.

  1. Pakistan 81.2% the same · grid twin Pakistan generates 11.4 points more solar than Romania
  2. Slovenia 76.9% the same Slovenia generates 18.8 points more nuclear than Romania
  3. Chile 75.8% the same Chile generates 20.5 points less nuclear than Romania
  4. United States 74.9% the same The United States generates 23.0 points more gas than Romania
  5. Spain 70.6% the same Spain generates 14.8 points less coal than Romania

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
