Computer energy saver

In the U.S. alone, computers that are left on while idle leave a footprint of millions of tons of carbon dioxide a year. The Ecobutton ($22) plugs into your computer’s USB port to make power saving easy. Press the button, and the included software turns off everything in your computer except crucial memory, shrinking its power use to a mere 1.8 watts—a much deeper sleep than standby mode. Touch the keyboard, and all programs quickly return to normal. For an intriguing extra, Ecobutton software also tracks how much you have decreased your computer’s
carbon footprint. Currently PC-compatible only.
