But will that prediction enable you to scale demand? With increasing hardware lifecycles, it might one day be economic for a global like Google to overprovision datacenters enough to be able to shift compute load to wherever intermittent energy is available. Requests can be routed over much longer distances than energy. But I suspect that Moore's law just isn't dead enough yet to make it economical to keep large datacenters offline just to wait for locally favorable energy prices. And on this scale, economical is a pretty good first approximation of ecological.
