Exactly. The issue is with the source of electricity, not with the AC itself. Not to mention that leading by example is nice, but it's not always the best course of action. An individual avoiding AC is a drop in the water, and not going to save the planet, while suffering immensely. Hell, even if every single individual stopped using AC at home (which isn't even close to reality), that wouldn't have a significant effect, compared to what corporations, factories, etc. are doing.
