Wasting Energy

The Atlantic Monthly comments on a way for the US to siginifcantly reduce its energy use: capturing wasted energy.

Except:

The U.S. economy wastes 55 percent of the energy it consumes, and while American companies have ruthlessly wrung out other forms of inefficiency, that figure hasn’t changed much in recent decades. The amount lost by electric utilities alone could power all of Japan.

A 2005 report by the Lawrence Berkeley National Laboratory found that U.S. industry could profitably recycle enough waste energy—including steam, furnace gases, heat, and pressure—to reduce the country’s fossil-fuel use (and greenhouse-gas emissions) by nearly a fifth. A 2007 study by the Mc­Kinsey Global Institute sounded largely the same note; it concluded that domestic industry could use 19 percent less energy than it does today—and make more money as a result.
