This study disagrees after taking into account storage.

Storage and production of renewables is also done by shipping in Chinese products created burning coal and ignoring environmental concerns. This all hinges on exporting emissions and labor to areas that don't care about pollution.
I'd also argue that nuclear tech can likely proceed faster than storage, given the dangerous nature of energy storage. Even something as basic as storing water can cause deaths given what happens when dams break, stored energy is volatile by nature.
You're also burning lignite coal now, which you take from Africa who is now having blackouts. But it went pretty poorly overall phasing out nuclear for renewables.
