Except that the trick to eliminating fossil fuels for electricity production doesn't just require renewables to deliver cheaper electricity; it has to follow load, something it can't do, which requires all of the traditional generators to remain in operation.

If a technology makes other technology that can't be dispensed with more expensive, it's a lie to say that technology is "cheaper". For a technology to even be considered "alternative", it must at least be capable of all the same tricks of the old technology, at which point the old can be abandoned. We're not there yet, and it isn't clear what the pathway(s) forward will be. There is no single solution for all markets unless some breakthrough like fusion so cheap nothing else can compete is developed.
