There isn't remotely enough storage available to make wind and solar feasible. To put this in perspective, the world consumes 60 TWh of electricity daily, about 2.5 TWh per hour. We have only a couple GWh of battery storage. Hydroelectric provides more, but that's harder to scale because you need the right geography.
Once solar saturates daytime demand, provisioning further solar power doesn't contribute to decarbonization. This is why nuclear is really the only known path to decarbonization. Maybe we'll figure out scalable ways to provision hundreds of terawatt hours of storage, but we might be waiting a long time.
