Countries With a Similar Electricity Mix

Ember annual, 2025

The United States's closest match is Russia, 80.4% the same, and the match goes both ways, so they are grid twins.

  1. Russia 80.4% the same · grid twin Russia generates 11.4 points more hydro than the United States
  2. Japan 75.1% the same Japan generates 15.5 points more coal than the United States
  3. Romania 74.9% the same Romania generates 23.0 points less gas than the United States
  4. Armenia 71.0% the same Armenia generates 16.3 points less coal than the United States
  5. Greece 70.7% the same Greece generates 17.4 points less nuclear than the United States

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
