A review of electricity monitoring and feedback systems

This paper reviews various products available in market and under study, which monitor electricity consumption and provide feedback of the energy usage. Energy usage feedback systems are categorized into three groups: (i) socket monitoring systems, (ii) whole-house monitoring systems, and (iii) whole-house monitoring with breakdown to individual appliances. In the future directions section, the paper describes a proposed energy usage feedback system, which provides feedback about individual appliances. This system also considers the effect of human behavior on energy usage and suggests a possible solution.
