TED - The Energy Detective - is an easy-to-use, accurate electricity monitor that can help you save 10% to 20% (or more) on your energy bill. This handy device provides immediate feedback on your energy usage so you can determine where and when to reduce your electricity consumption to save money and the environment.
TED is available alone or with data-logging software, called Footprints, that allows you to see your energy consumption in depth on your computer.
Installation is quick and easy. A transmitter is installed in your breaker box and the display unit can be plugged into any outlet in your home. No wires need to be run at all!
