Ya...but...Google sez; "The Earth is 123 billion acres in size, of which 37 billion acres are land. This means that there are a notional four acres available for every man, woman and child in the predicted 2050 world population 0f nine billion, which would be an increase of two billion on the present population." So there's some elbow room yet.
We are blessed with lots of acreage in garden spots like Nevada and Wyoming. Some of best places them are offshore. Turbines are getting much more reliable and robust. In fact, FP&L said the turbines in the path of Irma were undamaged.
Google also sez, "An average 1.5-MW turbine (26.9% capacity factor) would produce the same amount of electric energy as that used by almost 332 households over a year. It must be remembered, though, that wind power is intermittent and variable, so a wind turbine produces power at or above its annual average rate only 40% of the time."
That means your notional figure of 2 acres per household is extremely conservative, since even big turbines don't need 150 acres each.
... we need some acreage to grow food on too, right?
And that might become a bigger problem.
