From your quoted link:
“China’s total renewable energy capacity exceeded 1,000 GW in 2021, accounting for 43.5% of the country’s total power generation capacity…”
The term ‘capacity’ is doing a lot of heavy lifting here. Capacity UTILIZATION is a completely different matter.
For example, Alberta has 12,988 MW of fossil fuel capacity, and 3,246 MW of wind and solar. That’s a lot of renewable capacity. Over 20%.
However, at this moment, this is what our actual generated energy looks like:

For example, Coal energy capacity in Alberta is 1266 MW. Wind, on the other hand, is 2269 MW. So we could advertise that we have almost twice as much wind power generation capacity as coal! Man, we look green. Except that wind is currently at 3% capacity factor, and coal is at 99.5%. So in terms of actual generation, wind is currently providing 69 MW of power, and coal is producing 1260 MW. The picture for actual generation looks very different than capacity.
Solar is doing better today, because it’s the middle of the day in the middle of the summer. Even so, it’s only operating at 61.7% capacity. And in a few hours it will be zero.
So even though we have quite significant solar and wind CAPACITY, in reality we still rely on fossil fuels for between 85% and 95% of our power, depending on conditions.
If we did a crash program to double our wind and solar capacity to about 40% of total capacity, today it would be producing 13.4% of our energy. Again, that’s almost best-case. Last night that 40% capacity would have provided 2.2% of our energy. Meaning we have to keep the entire fossil fuel capacity in place. And that’s true even if we quadrupled capacity. Wind and solar capacities do not come close to equalling fossil fuels which can run at close to 100% of capacity.
And winter is very, very much worse.
So don’t be fooled when countries brag about their renewable capacity. Germany has enough wind and solar to provide over 100% of their power if you just look at capacity, but in reality they are increasingly relying on Russian gas and severe energy shortages are looming.
BTW, that Ab energy twitter account is worth following. It’s a bot account that aggregates the public energy numbers and posts them hourly.
