I love Green gadgets, and I’m not just talking about their color. The ECO Button is a small device that connects to your Windows PC (sorry, no Mac support at this time) through the USB port. When you aren’t using your computer, you can press the Eco Button and your computer will go into energy saving mode. When you come back to the computer, pressing any key on the keyboard will instantly wake it back up to where you left off. The included software will also display how much power, money and green house gases you have saved by using this device. The Eco Button is available now for $13.70 from EFO.
