Maybe we should be looking inward as to why solar isn't more easily deployable in the US. Local zoning, permitting, and community opposition are some of the top road blocks there...
Australia is experiencing this problem now to a limited extent, and is walking in to a disaster scenario with the scheduled shutdown of 5 gigawatts of coal fired electricity generating across three sites over the next three years with nothing in the pipeline to replace that 5GW.
Like it genuinely sounds like you're suggesting our current terrible system shouldn't even be attempted to be improved unless there's a magic perfect solution to replace it.
