New York Times:

One high-definition DVR and one high-definition cable box use an average of 446 kilowatt hours a year, about 10 percent more than a 21-cubic-foot energy-efficient refrigerator, a recent study found. “If you hit the on/off button it only dims the clock, it doesn’t significantly reduce power use,” said Noah Horowitz, senior scientist at the natural resources council.

More than the fridge? Dims the clock? Seriously?

cable boxes are power hogs.
