Oh No!  It's those awful cars that use gasoline!  It's those furnaces that use natgas!  It's all manmade mayhem!  We must stop, get a propeller for your house, get a plug for your car, it matters not that others aren't doing so, Americans must bow down to big enviro, must pay more to heat your home with hundreds of roof panels, all paid for by subsidies from the same people, those huge propellers, dotting our landscape must be paid for, look at how efficient they are, why why, they are....aren't they?
