This is happening despite the fact that the renewables aren't ready yet to sustain a reliable grid.
This is becoming less important. Factory work is becoming more automated and the core of the "smart grid" concept involves electricity producers informing electricity consumers as to when they are permitted to use power. Industrial users are already being moved to these sort of systems but the vision is for entire societies to participate in essentially cooperative power distribution. The power can be used when the power is there, aside from the demands which basically keep people working. A little more stock will have to be carried so that the workers can keep assembling the widgets, but more and more widgets are now being assembled by machines as well.
