A home energy monitor provides prompt, convenient feedback on electrical or other energy use. Devices may also display cost of energy used, and estimates of greenhouse gas emissions. Various studies have shown a reduction in home energy use of 4-15% through use of home energy display.^[1] Electricity use may be measured with an inductive clamp placed around the electric main, via the electric meter (either through an optical port, or by sensing the meters actions), by communicating with a smart meter, or by direct connection to the electrical system. The display portion is remote from the measurement, communicating with the sensor using a cable, power line communications, or using radio. Online displays are also available which allow the user to display near real-time consumption on any device that can connect to the Internet.

A possible means to reduce household energy consumption is to provide real-time feedback to homeowners so they can change their energy using behavior. Recently, low-cost energy feedback displays, such as the Cent-a-meter, The Energy Detective, Eco-eye[1], Envi[2], Flukso[3], PowerCostMonitor[4], PowerWatch[5], Silk[6] or Wattson[7] have become available.

A study using the PowerCost Monitor deployed in 500 Ontario homes by Hydro One showed an average 6.5% drop in total electricity use when compared with a similarly sized control group. Hydro One subsequently offered free power monitors to 30,000 customers based on the success of the pilot.^[2] Blue Line Innovations also indicates 100,000 units in the market today.

-Energy monitors are big in the UK with the country's largest utility companies providing them as part of their green/low income tariffs. [http://www.currentcost.com/ Current Cost] is the UK's leading manufacturer of real-time energy monitors and is expected to  will sell its one millionth monitor at the end of February 2010. The message in the UK is "use it, don't waste it". So use the gadgets you've invested in, but don't waste energy i.e. when you're not using the large flat-screen TV turn it off rather than leave it on stand-by.
