As I told some of the eco-fools at a former employer, you may not know what you think you know about conserving energy. I'm all for efficiency, and conserving anything that I pay for, such as energy, is great as long as it doesn't adversely impact my life. (Example--you'll save a lot of money if you turn your thermostat down to 60 in the winter, but it's going to be darn cold in that house.)
However, as one person at the current employer has noted, it's perfectly possible to "save your way into mediocrity."
Not that eco-fools would believe that.
