Taiwan
TWNGas overtook coal on Taiwan's grid in 2024.
Today gas supplies 49% and coal 36%.
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 2 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.
Taiwan 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.
Most of the fuel behind this grid is bought from abroad.
What this means
How much of what this grid runs on the country can supply itself. Sun, wind and water count fully, because nobody can cut them off; coal, gas and oil only as far as the country digs them up. A high score is not the same as a good grid: mining your own coal scores well, importing uranium scores badly.
Also true of Taiwan
Taiwan uses far more electricity per person than countries at its income level.
12,478 kWh a year, against a median of 6,775 across the 43 high-income countries here.
Gas overtook nuclear on Taiwan's grid in 2005.
Today gas supplies 49% and nuclear 1%.

Figures are for 2025, the most recent year reported for Taiwan. Generation shares are a percentage of electricity generated, not of energy used. How this is calculated.
