The difference between China and Germany is that China has an entire continent and the capability to rapidly deploy HVDC lines across all of it. This means that their wind/offshore wind may have a capacity factor of 30-49% but the wind will be blowing at different times. Similarly, they can take advantage of solar generation in Western China that continues well into the evening. And finally, China is building out battery and storage capacity at a pace that rivals their investments into renewables. If you’d started in 2011 and predicted the current renewables cost/buildout rate in China, people would have laughed at you. I would not bet against a similar thing happening with storage over the next dozen years. TL;DR: China decarbonizing is very good for the world, even if it isn’t perfect yet. We in the west should stop looking for reasons to repeat our earlier (wildly incorrect) pessimism about renewable capacity, and just start trying to catch up.
