We told you about the Google PowerMeter service and other devices to measure energy use in your home. Joe Hutsko of the New York Times has this piece on the Energy Detective, yet another green gadget that helps you understand your personal energy consumption. The device retails for about $145.
The biggest lesson Hutsko learned when testing the Energy Detective? Turning his heat down just a little in the winter could cut his bill to a third.
Do you own one of these tools? Has it helped you reduce your electric bills?
