They build renewables out west yet don't have the grid yet to move any of that power to the east where it would be used. So the rate of renewable production is still far higher than renewable consumption.
They will probably fix that eventually, but it just goes to show about the weirdness of rapid growth.
Also, china will never have the renewable capacity of Norway, which gets almost all of its electricity from hydro.
I'm sure, the question is always grid capacity vs. production that can't be used locally. Also, some of the renewables are pretty remote and don't have grid access at all yet.
