More than a quarter is still pretty good. And I think most people would call hydro a renewable energy source. Still better than fossil fuels for sure.
They're building 2/3 of the worlds wind and solar capacity each year so this will likely just keep increasing.
We're still arguing about whether global warming is real and they're smashing it. A bit embarrassing really.
They seem to be making better progress than many other countries on renewables.
Hopefully they'll transition off coal and onto battery infrastructure as renewables increase.
