Drivers and barriers to energy-saving behaviour formation and retention in response to extreme events: insights from the energy crisis
摘要
This study investigates the medium-term effects of the European energy crisis on household energy-saving behaviours, using two-wave longitudinal survey data from Norwegian households collected in May (N = 3,514) and November 2023 (N = 2,289). Challenging prior claims that external cues trigger only short-lived behavioural change, we found that 88% of the households were actively engaged in at least one behaviour-based energy-saving measure by May 2023, and 65% of those continued these behaviours six months later. By tracing how crisis-driven awareness translates into motivation, actual behaviour, and retention, we identify the demographic, social, and contextual cues that shape each stage. Older respondents, longer housing tenure, and residence in northern regions increased the likelihood of converting awareness into motivation; age and bill-payer status influenced the translation into behaviour; and female respondents as well as those adopting new heating systems were more likely to sustain changes over time. Methodologically, the longitudinal design enables a rare test of behaviour retention in real-world crisis conditions, advancing behavioural theory on cue-driven change. Substantively, the findings offer policy-relevant insights on how to support long-term household engagement with energy saving beyond immediate crises.
