We have a windmill farm in NW Indiana, clearly visible from I-65, near Lafayette. I have no idea how much energy it produces, but I’ll say this: one windmill is quaint-looking; an entire windfarm takes up a huge geographic footprint, and is an eyesore. I can’t believe environmentalists go for this. Not only are they ugly, surely they kill birds and affect other wildlife.
As I’ve posted repeatedly on FR, I’ve never seen ANY of those turbines spinning.
