Reducing or eliminating unnecessary electricity consumption,
. . . is an effective method of decreasing home energy costs,.

MIT researchers, have a sensor system with software,
. . . that you simply ziptie a small sensor onto your home’s incoming electric line, and
. . . have it automatically determine exactly how much electricity is being used,
. . . by which devices, and when.

“First, it involves no complex installation:
. . . No wires need to be disconnected, and
. . . the placement of the postage-stamp-sized sensors over the incoming power line,
. . . does not require any particular precision,
. . . the system is designed to be self-calibrating.
Second, because it samples data very quickly,
. . . the sensors can pick up enough detailed information about spikes and patterns in the voltage, and
. . . current that the system can, thanks to dedicated software,
. . . tell the difference between every different kind of light, motor, and other device in the home, and
. . . show exactly which ones go on and off, at what times.”

Cost = $25 to $30 per residence.
