When I was doing work on wind farms (before all the subsidies were cancelled) the most difficult parts were logistics. Putting up a big pole with a fan is easy. And then...
We had to widen roads to accommodate those long ass trucks, for one. Then, the routing for the transmission lines. That was a bitch and a half.
Anyone ever see the caissons these big poles are anchored to? Holy hell.
Not to mention finding willing landowners to grant leases/easements and then permitting.
People seem to not think about all that goes into these things. It ain't just putting up a pole with a fan.
