Additionally, quite a bit of the need for storage can be substituted by overbuilding long distance power transmission lines. That may be cheaper, if NIMBYs can be neutralised. I read a factoid many years ago that wind speeds are only 10% correlated at a distance of 1000 km. Don't know how true it is, but it seems plausible at least.
