Papua New Guinea
PNGHydro overtook gas on Papua New Guinea's grid in 2023.
Today hydro supplies 21% and gas 19%.
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.
Cleaner than 4 in 10 grids worldwide.
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.
Papua New Guinea 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.

Papua New Guinea's electricity is dirtier than the world average.
514 grams of CO2e a kilowatt-hour against a world figure of 458 — 12% above.
Papua New Guinea is first in Oceania for gas.
Gas supplies 19% of its electricity.

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