Despite the Rebound, Energy Efficiency Really Works
Robert J. Michaels's "The Hidden Flaw of 'Energy Efficiency'" (op-ed, Aug. 21)) couldn't be more flawed itself. Energy-efficiency improvements over the past 40 years for refrigerators, air conditioners and other household energy hogs are on track to save Americans $1 trillion in energy costs while delivering better service. The air conditioners that helped keep us cool during record heat waves this summer, for example, are 30% more efficient than they were a decade ago, delivering more comfort for less money while wasting less energy.
Energy-efficiency standards have also helped the U.S. avoid India-style power outages. They've also substantially reduced dangerous power plant pollution that hurts our kids. Those are all benefits—not flaws. The issue of "rebound" raised by Mr. Michaels has been studied for decades. There is absolutely no evidence that increased usage of more efficient appliances leads to any significant reduction in energy savings.
