I'm not talking about smoothing our minor variations in output. I'm talking about enough storage so you don't need fossil backup at all, even if the wind dies down over a large area for a couple days. Battery backup at that scale is not affordable with current technology, but that's what we'd need if we actually got rid of fossil.
