Well, Al Gore flew around a lot in a private jet as I recall. And he lives alone in a mansion. Very energy inefficient. Yeah, hypocrisy here is rampant in my opinion.
Al Gore's mansion is completely powered with solar energy. If you are using Republican smears, you should be aware they're lies.
For those critiquing George Clooney and Leonardo diCaprio here (and maybe deservedly so) I think it's safe to say neither the Koch Brothers nor Rupert Murdoch weren't part of the 400 people in the study. They would have completely skewed this small sample the other way.
