Sierra Club is well known for this. They have come out in support of wind farms in major bird migration flyways, and poo-poo concerns of bird-strikes related to turbines, etc.
It got so bad with them that some local chapters of The Nature Conservancy and other groups who buy land to put in protectorship have ended cooperation with the Sierra Club. Someone (now retired) at the Cornell Ornithology Lab told me that the Sierra Club has lost a lot of cachet in the Lab over their support of wind turbines, etc.
Nice to hear
