Wind currently produces about 2% of the energy used in the US (see link) and remember, the survey talked about 57,636 turbines so they are not really started yet. It relies on other energy sources to plug the gaps when the wind is not blowing so some magic is required in that area to make it viable.
Currently it works only because it is such a small fraction of the energy used and the existing fossil-fueled power stations are not being shut down. Basically, they are milking the subsidies, claiming the moral high ground but, in reality, relying on the technologies they are claiming to replace.
I always smile when I see: "... will cause more ... than previously thought." It makes you realise just how settled "the settled science" really is. If it really was settled then it would happen just as you thought and not "more than".
Based on the 2% and 57,636 figures above it means that the US will need about three million turbines if everything is to be wind powered. Three million 400 foot towers all sapping large quantities of energy from the wind is going to do something isn't it?
Of course it is not just three million turbines. You will need three million access roads as well for building and maintenance purposes. Then you have an extra three million roads to maintain ...
