Why would a progressive society revert back 400 years in energy technology ?
We already tried it once.
Wind energy is expensive and getting approval for transmission lines is difficult if not impossible at times.
Wind as opposed to solar is too noisy for human inhabited neighborhoods.
Just watch an old movie filmed near windmills in Holland and you'll understand.
Ask Boone Pickens , he was big time wind until the future war over transmission lines turned him off.
In the meantime he had invested $2B in it and then went natgas.
It has it's place as a part of the total energy package but at what price to the tax payer and consumer ?
Also eco-freaks claims wind towers kill millions of birds annually.
