Energy conservation has gained attention from the perspectives of climate change and energy security. It has been noted that nonprice factors, such as social norms, influence people’s energy saving practices. I have examined the nonprice factors influencing individuals’ and firms’ energy saving actions.
Recently, I have conducted several field experiments. In collaboration with a private hotel, I implemented an experiment with hotel guests. Furthermore, I participated in an experiment to “nudge” Philippine households towards energy savings.
I am also engaged in a study on the promotion of an energy-saving air conditioner in the Philippines. These studies in the Philippines are carried out in collaboration with Prof Majah Leah V. Ravago, Ateneo de Manila University.
I am also conducting a comparative study of Japan and Germany in collaboration with Prof. Dr. Andreas Ziegler, University of Kassel, Germany.
