How Much Power Do Your Electronics Use When They Are "Off"?

The NYT has an article that may be of interest to the more energy conscious among you. If you think that a device always uses a lot less power when it's off, think again.

My cable box drew 28 watts when it was on and recording a show, and 26W when it was off and not recording anything. Even if I never watched TV, I would still consume about 227 kilowatt-hours annually. To put it in context, that’s more than the average person uses in an entire year in some developing countries, including Kenya and Cambodia, according to World Bank estimates. Always leaving a laptop computer plugged in, even when it’s fully charged, can use a similar quantity آ— 4.5 kilowatt-hours of electricity in a week, or about 235 kilowatt-hours a year.
