People who leave their computers on 24/7 have a new gadget that will save some energy. Attach the Ecobutton to your PC via USB and if you leave your desk, it will put your computer on “ecomode.” Even better, it will record how much power, money, and carbon units you have saved. Tap a key and it turns back on. Made from recycled plastic, it will keep track of the last time it was used and the total over time. Guilt just doesn’t get any better for £14.95 (~$29.00.)
