But your waistband won't. Most Americans want to cut down on calories but don't, even though the results of failure are personal and unpleasant. Buying a bigger refrigerator won't make you feel miserable tomorrow. It's quite a convenience, really. You need it for all your diet soda.
Efficiency remains a perfectly sensible thing to pursue.
It is as useful to save energy as it is to save time or Christmas wrapping paper. Which is to say, sometimes it's worth the trouble, sometimes it isn't, and we don't need a federal program to force it on us. For the happy few who include them in a real diet rather than a fake one, low-fat potato chips offer a chance to brighten an otherwise spare meal. That's about all the people who sell such chips ever promise. Which makes them the most honest people you'll hear from in the whole energy conservation caper.
