Air Conditioning

I've always felt uncomfortable with ACs in homes. I agree its to prevent one from the heat, but at what cost? All we do is pump more hot air into the planet.
What we forget is that we are consuming more energy - energy that comes from fossil fuels mostly - to run our ACs. Not to forget the CFCs powering them.
We have had horrid summers all across the world this year and its to continue. Global warming is very much upon us. This may look alarmist, but with the US president being backed by Oil and energy bucks, I doubt we could expect anything substantial for the environment other than plain denials. Reality says otherwise.
I still believe that humans can somehow manage to really outwit nature somehow and stem the warming, either by increasing the ozone concentration or some equally crazy idea. But by when? When its too late?
Really its not that tough to lead a lifestyle more in tune with nature and a lifestyle that is sustainable.
