Sure. They're maxing out production of renewables and supplementing with nuclear. As renewable production ramps, it displaces more nuclear. We're doing the same thing, except with natural gas. If we could deploy infinite renewable energy instantly, that would obviously be preferable. But we can't. So China gets nukes and we get gas. Almost certainly for the next 50 years. (Good luck to whoever has to fight natural gas's lobbyists in ten years when they think the brand-new LNG terminals are going to go down without a fight.)

  • Nuclear doesn’t provide the kind of dispatchable power you need to supplement a renewable grid. Nuke plants of the type China is building can’t be spun up and down fast enough. China is currently planning to build a renewable grid backed by fossil fuels just like the US, except they’re using modern coal plants (and paying them not to generate) and we’re using gas. Ultimately it seems likely that coal will be replaced with pumped hydro and battery storage as prices drop, and the nuclear plants will have fewer and fewer profitable applications.

    But there’s nothing wrong with all that. China conducted a natural experiment with multiple technologies and renewables and storage appear to have won big. The important thing is that those of us outside of China can learn the lessons without having to repeat the experiment.

  • We (and the Chinese) can deploy renewables (and storage) much faster than nuclear.

    I suspect the only reason China is continuing to build NPPs is inertia, and a desire to not amputate that part of their industrial sector. The grandiose plans have been scaled way back. But that can continue for only so long before it's written off.
