If you want to turn all of your office equipment and lights off at the same time, you can do it with an INSTEON system. Put the on/off switch beside the office door to rest assured that lights, printers, and other items aren't silently sucking money out of your bottom line every night. Don't put computers on this kind of system; follow the next tip instead. It's also worth investing in smarter power strips that reduce the standby power drained by gadgets that aren't in use. Belkin has a number of easy-to-use gizmos to help control the power demands of everday equipment.
8. Use Your Computer's Power-Saving Mode
Every computer can be run in power-saving mode. In Windows 7, go into your control panel, and then choose Power Options and Power Saver, except where you really need your computer to run at peak performance.
