China strategy is clearly a mix of renewable and nuclear, renewable for bulk and nuclear for baseload.

At the moment, they are quickly building gaz-fired capacity to supplement the renewable during peak demand and when production is low. Their base load is mostly coal. Nuclear will allow them to phase out most of that. They are clearly targeting zero coal and are gaz poor anyway so nuclear allows them to limit their exposure to imports. That's basically France strategy in the 70s except France went all in while China can use renewable for bulk capacity as they produce a ton of the required mineral themselves

The opposition between intermittent and nuclear doesn't exist. Nobody knows how to run a grid purely on intermittent sources.

A lot of the discussion on statistics here don't make sense. China wants to switch off coal and gaz. You are looking at transition numbers focusing on current shares when you should be considering trajectories.
