There was an estimate of the cost of keeping up with demand using wind - and the back-of-the-envelope numbers were discouraging. 2TW per year, and wind power takes a huge investment in the towers to produce relatively tiny amounts of watts.
And they look ugly as well. Personally I hope we can get rid of wind turbines as soon as possible.
When they're situated in windswept plains, they do not.
(I do/help with these assessments)
