Abstract
Though numerous studies into household energy-saving behaviors exist, studies tracing long-term behavioral change are rare. Addressing this gap in research, the present study focuses on participants'qualitative change in energy-saving. The study wascarried out over one year, aspart of a local energy-saving campaign. Participants in the current study were all enrolled in the year-long campaign, and participated in group interviews. Participants' statements were analyzed via text mining, after which expression frequencies and relationships between words were examined. Results showed that economic gain, heating, and ease of seeing the fruits of one's efforts presented at the beginning of the project were often mentioned during the first half-year group interview. In the final half-year group interview, however, there was an increase in comments regarding how not only oneself but also how family life had changed, and also regarding new initiatives put into practice by participants themselves.
