Storage exists, but it's insufficient and expensive.
We need 30x, or maybe 100x more storage. After that, we could live on renewables only, and keep gas-fired plants only as a disaster-recovery tool, like diesels in datacenters.
Until then, we need stable generation which does not spew CO2, which is, well, nuclear. It's hard to tell if ubiquitous cheap utility-scale batteries emerge in 5 years or 50 years.
