Countries With a Similar Electricity Mix

Ember annual, 2025

Greece's closest match is the Netherlands, 85.4% the same, and the match goes both ways, so they are grid twins.

  1. Netherlands 85.4% the same · grid twin The Netherlands generates 5.9 points less hydro than Greece
  2. Italy 76.4% the same Italy generates 12.8 points less wind than Greece
  3. Ireland 74.5% the same Ireland generates 16.4 points more wind than Greece
  4. Spain 72.7% the same Spain generates 18.8 points more nuclear than Greece
  5. Jordan 71.6% the same Jordan generates 21.7 points more gas than Greece

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
