> China is pursuing the strategy you're describing, but there's a reason they're also building nuclear, they're increasing LNG infrastructure, they haven't phased out coal, and they've built a huge amount of oil storage.

This opinion is rather simplistic. China is reported to have 60% of it's energy needs already supplied by renewable sources, but this transition creates different types of challenges such as preserving the power grid's inertia. Otherwise you might see yourself in a scenario such as the Spanish blackout. This means having in place strategies for fast response (gas) and baseline (hydro storage, nuclear) to prevent the scenario.

batteries are the fastest response power. gas is high maintenance, & bad capex as an intermittent source.
