% of the electricity mix 1985–2024 · OWID (Energy Institute + Ember) · ~179 countries
Oil's share of each country's electricity production, as a percentage — nine data points from 1985 to 2024. A very skewed distribution: near zero for large economies, up to 100% for many small islands with no other source available.
Our World in Data (Energy Institute + Ember): about 179 countries covered, against about 31 with the Energy Institute source alone.
Time slider. A saturated shade almost always signals an isolated grid rather than a deliberate energy choice.
Five territories — Gambia, Grenada, Guinea-Bissau, Montserrat, East Timor — draw 100% of their electricity from oil: small island or landlocked economies with no interconnected grid or other source available, and not oil producers (East Timor excepted).
