That's the point. If you waste energy when it's comfortable out, you might not have that energy when you really need it! Extreme heat won't kill you like extreme cold will. If most people had the option of being allowed to use heat during the winter or AC during the summer, which would they pick? Heat of course. I'm not saying to never turn the AC on, but most people turn it on in May and let it run until Nov. Last night it got down to 60 degrees agarin with no humidity. Why would anyone leave their AC on and their house closed up? A complete waste of energy. It's not a matter of cost, it's a matter of limited natural resources. This generation should know much better than my generation about conserving energy but apparently not. But don't worry, Al Gore is watching you and he knows exactly how many kilowatts you have wasted!
