The real challenge is of course bringing down cost of storage, which is the key to make solar systems efficient (not just cheap).
Wind has a scalability problem. Residentially, it's only a good sell as a backup supply for when solar isn't cutting it to hopefully prevent generator use. And even that's a tough economic argument.
Towers have huge economies of scale, both in total size and height. So the turbines just keep getting bigger and bigger because it's more and more cost effective.

English Channel = 35km (narrowest point)
35 * 60 / 85 = 24.7 biscuits!
