Countries With a Similar Electricity Mix

Ember annual, 2023

Reunion's closest match is Guadeloupe, 66.7% the same.

Guadeloupe 66.7% the same Guadeloupe generates 21.2 points more other fossil than Reunion
Guatemala 66.2% the same Guatemala generates 27.2 points more hydro than Reunion
New Caledonia 65.0% the same New Caledonia generates 33.9 points less bioenergy than Reunion
Nicaragua 64.0% the same Nicaragua generates 15.3 points more other renewables than Reunion
Estonia 62.7% the same Estonia generates 17.9 points more wind than Reunion

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
