Countries With a Similar Electricity Mix

Ember annual, 2025

Thailand's closest match is Bangladesh, 80.5% the same.

  1. Bangladesh 80.5% the same Bangladesh generates 12.0 points more other fossil than Thailand
  2. Hong Kong 79.4% the same Hong Kong generates 16.9 points more coal than Thailand
  3. Uzbekistan 78.8% the same Uzbekistan generates 11.0 points less bioenergy than Thailand
  4. Brunei 78.5% the same Brunei generates 17.6 points more gas than Thailand
  5. Mexico 77.1% the same Mexico generates 13.4 points less coal than Thailand

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
