The "intermittency" is an early adoption problem. When you have enough windfarms more uniformly supplying The Grid across the country, this issue will become less of a concern.
What I do see as a big problem is cost. Government subsidies aside, the cost of buying and installing turbines presently is no laughing matter. At scale, solar is rapidly becoming much cheaper to install than wind, which is increasingly becoming reliant on giant 3-5 MW capacity monoliths costing roughly 4-5 million USD a pop--not accounting for installation and maintenance over the long term, and supporting infrastructure and transmission lines to tie the windfarm into The Grid.
