Solar and wind are on an exponential trajectory. Our usage isn't. That in itself is enough to make a pretty good prediction that they'll make an impact.
That said, there are absolutely going to be issues taking the entire grid to solar/wind (namely, storage!). There are potential options to solve those problems...so we'll get there. The question is just how long it'll take.
