Energy use is what separates us from the cave people. Plus, most people who bitch about it are never willing to give up all the shit they have that uses energy. We should be looking for ways to use more energy. Ideally, we improve energy technologies and efficiency where we can, but using less just because some asshole thinks other people use too much is the exact formula for going back to the caves. I'll pass. They can go live that way if they want to.
