ABSTRACT This study examines the adoption and usage patterns of household energy apps among a sample of Norwegian households to explore their potential in visualising and controlling home energy consumption and influencing sustainable energy practices. Through a questionnaire survey of 150 respondents using energy apps, this study gathers empirical insights into adoption motivations, user perceptions and factors associated with self-reported changes in household energy practices. Findings indicate that app-related factors, such as perceived app insights applicability, ease of use, and appealing user interface, are more positively associated with self-reported changes in daily energy habits than demographic factors. This research underscores the importance of prioritising user experience and data security in app development to foster sustainable energy practices. It also offers practical recommendations for targeted engagement strategies and policy interventions to promote the wider adoption of smart energy apps and maximise their potential to facilitate household energy transitions.
