Countries With a Similar Electricity Mix

Ember annual, 2025

Singapore's closest match is Oman, 96.3% the same, and the match goes both ways, so they are grid twins.

  1. Oman 96.3% the same · grid twin Oman generates 2.8 points less bioenergy than Singapore
  2. Tunisia 95.1% the same Tunisia generates 3.6 points more gas than Singapore
  3. Qatar 94.1% the same Qatar generates 4.9 points more gas than Singapore
  4. Algeria 92.5% the same Algeria generates 7.5 points more gas than Singapore
  5. Trinidad and Tobago 91.6% the same Trinidad and Tobago generates 8.4 points more gas than Singapore

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
