Countries With a Similar Electricity Mix

Ember annual, 2025

Sri Lanka's closest match is Madagascar, 75.4% the same.

  1. Madagascar 75.4% the same Madagascar generates 24.3 points more other fossil than Sri Lanka
  2. Guatemala 73.7% the same Guatemala generates 21.2 points more bioenergy than Sri Lanka
  3. North Korea 73.7% the same North Korea generates 21.2 points more hydro than Sri Lanka
  4. Vietnam 73.1% the same Vietnam generates 18.9 points more coal than Sri Lanka
  5. Bosnia and Herzegovina 72.9% the same Bosnia and Herzegovina generates 26.9 points more coal than Sri Lanka

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
