Abstract
In these days, the global warming has been becoming a major concern. According to some news resources, the amount of CO2 emissions in the home in a year is much larger than that by a car. With this background, the objective of our study is to let home residents recognized how much they use electricity in their everyday lives and make them aware of home ecology. As a first step for this, we propose a method to verbalize the amount and the trends of electricity consumption so that they can recognize them easily.
