Guyana
GUYGuyana runs almost entirely on oil.
96% of its electricity comes from one source.
What this grid depends on
Three measures that say more about a country than how much power it makes. Open “what this means” on any of them if the term is new.
Among the most carbon-heavy electricity anywhere.
What this means
How much planet-warming gas is released to make one unit of electricity. Two countries can generate exactly the same amount and one of them be ten times dirtier doing it. Lower is better.
Guyana generates almost exactly what it uses, with next to nothing crossing its borders.
What this means
Electricity can be sold across a border like anything else, through high-voltage lines connecting one country's grid to the next. Buying it in means leaning on a neighbour to keep the lights on. Selling it means generating more than the country needs.
Also true of Guyana
Guyana's electricity is dirtier than the world average.
645 grams of CO2e a kilowatt-hour against a world figure of 458 — 41% above.

Figures are for 2024, the most recent year reported for Guyana. Generation shares are a percentage of electricity generated, not of energy used. How this is calculated.
