I agree that storage is a problem if you get most of your energy from solar, but in most places we're still in the mode of "on a sunny day we just burn a less coal or natural gas". In the long run it may become a bigger problem. Pumped hydroelectric storage should work great in places where the geography is amenable, and regular battery technology is getting better.
