To explore the dynamics of spouses' energy-saving behaviour, we surveyed the 732 Japanese couples. We identified the spouse responsible for monitoring energy consumption, making decisions about energy-saving investments, and taking the lead in daily energy-saving activities. We also looked at the characteristics of the spouses that influence these three types of energy-saving activities. The results show that husbands are more active in deciding on energy saving investments, while wives are more active in daily energy saving practices. The results also show that education increases the involvement of both husbands and wives in two types of energy saving behaviour. (98 words)
