A friend of mine recently installed a 'TED' (The Energy Detective) device in her home. The results were very interesting. Here's a bit of what she had to say about its impact on household behavior:
"We (well, my husband) installed an electricity monitoring device ("The Energy Detective") for our home. It connects to the main electric line into the house and monitors amps (I think), and connected to a breaker in the box, which then feeds info somehow to a remote detection unit (RDU) plugged into a corresponding outlet (it's movable, as long as the outlet is in the same phase as the unit on the breaker). The RDU displays current kW, cumulative daily kWh from midnight to midnight, and can also do dollars (but we haven't switched it to that view really).
The RDU happens to be plugged into the outlet in the upstairs bathroom (I'll spare you the details as to why, but has to do with renovation work going on in the house). Since we're often in that room and have a moment to pause and read it, it may actually be a good location! It has been interesting to see our reactions to it. Tonight, my husband yelled down to me "hey, what did you just turn on that uses 1500 watts??" (it was the toaster oven). As I was washing hands I watched it change up, then up again, then up again, then thought to myself - oh yeah, mom is here and must have turned on the lights on the stairs, in the basement, then in the bathroom. The most shocking thing thus far is our avoidance of the unit when the air conditioner is running and it zooms up to 4+ kW.
Another colleague of my husband's put one in their house. He has seen his kids become more aware of power consumption. The middle school boy tries to find things to unplug or turn off to get the number as low as possible. The teenage girl turns off lights now. BUT, their unit is in the kitchen and one evening he came into the kitchen to see his wife putting away the food that was to have been for dinner. She had watched the unit change upwards as she started using the microwave and stove and decided "it's too expensive to cook here, we're going out." evidence of the rebound effect."
