I Need Less Power, Scotty! Sometimes less is more. AC Cost Control ($30) is helpful for finding devices that pull power even when 'off.' I then use timed outlets, programmable switches (of course!), and other tricks to turn equipment on only when needed. Smarthome is a good source for such items." We've also seen the Kill A Watt ($40) device and the Watts Up Pro AC Power Meter ($150) advertised for this task, but we don't have any first-hand knowledge for comparison.
