All these points are indeed valid. Proponents of wind energy tend to downplay them.
But unfortunately, there are always trade-offs to make in energy extraction. There are a lot of similarities between a wind tower pylon and an oil well.
As for the farmers "not being able to make it" so they have to sign the wind contract, let's get away from the poor farmer myth. When a farmer signs such a contract, the value of his land goes up. He gets a windfall (no pun intended) when he retires. The buyer of that land made a choice to pay that price, which was in part determined by the wind contracts. Don't feel sorry if the new buyer cannot make it.
