Hong Kong
HKGGas overtook coal on Hong Kong's grid in 2020.
Today gas supplies 64% and coal 34%.
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.
Hong Kong buys in more electricity than it sends out.
What this means
The share of the electricity used here that was generated abroad and carried in over high-voltage lines. The higher it climbs, the more this country relies on a neighbour to keep its lights on.
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 Hong Kong
Hong Kong generates no hydro electricity at all, in a region built on it.
41% of grids in Asia draw more than a tenth of their power from hydro.
Hong Kong brings in 23% of the electricity it uses.
Its own power stations cover the rest.
Hong Kong’s neighbours
ChinaChina is first in the world for how much electricity it makes.
MacaoMacao brings in 88% of the electricity it uses.
TaiwanGas overtook coal on Taiwan's grid in 2024.
VietnamVietnam uses far more electricity per person than countries at its income level.
LaosLaos generates no gas electricity at all, in a region built on it.
Figures are for 2024, the most recent year reported for Hong Kong. Generation shares are a percentage of electricity generated, not of energy used. How this is calculated.
