"David C. Brown, a company lobbyist for the Exelon Corporation, noted that the federal government's subsidy to the wind-energy industry was partly responsible for the shutdown of a coal plant in Montana."

"Wind energy is like a (bad) vending machine. When you are most hungry, you get the least amount"

It's about who's getting financially screwed and who's the most connected in the US Congress.
