I was thinking we should come up with a list of electricity saving devices and devices that help save electricity. There are a lot of products out there and knowing what is out there can surely help us reduce our usage. So, if you know of, or use a product you like, please post it up and give picture, a quick blurb (even copy/paste the mfg's description) about what it is and what it does, and a link to the manufacturer's site would be good too.
I'll start things out with something I think almost all of us already have:
Kill a watt
The kill a watt is a well known product that allows you to measure the energy consumption of 110V AC devices (not 220V). Dislpays: Volts, Amps, Watts, Hz, VA, and kWh used since plugged in. There are several versions with some additional functionality like wireless display, surge protection, power strip, timer, etc.
