The fact that 50% of people still believe things like a TV, Microwave, and central A/C are "necessities" means we have a very long way to go. I guess I can be happy it dropped from 60%.
I would give up Internet before I gave up A/C. I've only seen one home in Tucson well enough insulated to give up A/C, and it was built, brick by brick by the owners, and only had two very small windows.
