Really not sure what your argument about China is. The vast majority of their energy production remains oil & coal. This follows from previous analysis that a focus on renewables means that your dependency on oil & coal remains. It’s telling that France is one of the few countries to go all in on nuclear & remains one of the few countries that has reliable year round carbon-free power generation (& a surplus that it exports to other countries). Germany went away from nuclear in favor of renewables & their reliance on fossil fuels went up.

If solar and wind were truly more scalable, they’d be significantly reducing our dependence on fossil fuels & yet they’re still not to this day. They offset some demand but demand grows faster than our ability to actually take away from fossil fuels.
