Assuming, of course, the wind is blowing. And therein lies the number one problem with wind turbines: there's no easy, cost effective, way to store the output. Solar panels have the same problem at night.
Personally I think all this "green" alternative power stuff is sorta cool. Just don't use my tax dollars to fund it.
It is cool technology. And when faced with US$20K to run power to my shack in NM, US$6K didn't seem so bad. The ROI numbers changed quickly.
As for your second point.... AMEN! NO TAX DOLLARS! SINK OR SWIM.
Solar makes sense in some cases. My shack in the mountains was one.
Here in suburbia? Oh heck no!
I couldn't make payments on a 2% loan for what I pay TXU for 'lektrikity.
