Home Energy Management System (HEMS) is a technology to reduce and manage home energy use. The feedback on energy consumption to energy users is known to be effective to reduce total energy use. A typical HEMS just shows the energy consumption of the whole home and home appliances. Users cannot figure out how efficient a home appliance is, compared to the others. So it is necessary to compare the energy usage of home appliances to that of the same kinds of home appliances. In this paper, we propose a green HEMS based on energy comparison.
