Abstract
Mass consumption of energy is a big problem. Energy-saving activities which are a solution to this problem have been attracting a lot of attention. Nevertheless, in order to engage in thorough energy-saving activities, consumers need support; on the other hand, even with support, the effects seem to be only temporary. In this paper, in order to obtain a long-term effect, we focus on developing a method to raise consumers’ awareness about energy-saving behavior. To this end, we designed an interface which offers consumers the cue to think about energy-saving activities and conducted a 2week-expriment using the interface with 10 participants. The results suggest three things. First, the participants became aware of the importance of thinking about energy. Second, the participants clearly understood which energy-saving activities are important, and which are not. Third, the more times they perform an activity, the less likely it is that they will change their way of thinking about the activity as time passes.
