A few weeks ago we mentioned the, a device that indicates which appliances are doing the most damage in your monthly power bill. But a lot of green power strips are taking a more aggressive approach than just tracking numbers.
The "Powergard," for example, claims to store energy that would otherwise be wasted in the operation of inductive motors and then recycle it later, according to Electronic House. It also functions like a standard strip, regulating surges and power spikes.
Nevvus, which makes the Powergard, says it will save consumers up to 10 percent on utility bills--that is, after the initial $200 outlay for the device. But if you live in Buffalo, that could cost could be made up in just a couple of winters.
