This report from the American Council for an Energy-Efficient Economy (ACEEE) states that a variety of new feedback initiatives – including real-time web-based or in-home feedback devices and enhanced billing approaches – are making energy resources visible to residential consumers. These initiatives are opening the door to potential energy savings that, on average, have reduced individual household electricity consumption 4 to 12%. If broadly implemented throughout the United States using well-designed programs, residential sector feedback programs could provide the equivalent of 100 billion kilowatt-hours of electricity savings annually by 2030. The report concludes that advanced metering initiatives alone are neither necessary nor sufficient for providing households with the feedback that they need to achieve energy saving; however, they do offer important opportunities. To realize potential feedback-induced savings, advanced meters must be used in conjunction with in-home (or on-line) displays and well-designed programs that successfully inform, engage, empower, and motivate people.
