Why do people turn down the heat? Applying behavioural theories to assess reductions in space heating and energy consumption in Europe

Reducing heating-related energy consumption is vital in Europe, where it accounts for a significant portion of domestic energy usage. We studied the factors that influence reduced heating-related consumption by using three theoretical frameworks: the Theory of Planned Behaviour, the Value Belief Norm theory, and the Prototype Willingness Model. Our sample consisted of 3098 people from 29 European countries. We conducted a confir-matory factor analysis to verify whether our observed variables measure our latent factors, followed by a structural equation model that incorporated these three behavioural models. We find that perceived behavioural control, subjective norms and attitudes (as part of the Theory of Planned Behaviour) are significant predictors of intent to reduce consumption. However, perceived behavioural control was not statistically significantly asso-ciated with behaviour. Environmental concern had a more significant influence on attitudes towards energy reduction than bill consciousness. Attitude was additionally significantly associated with fear of losing comfort and energy knowledge. Moreover, personal moral norms (as part of Value Belief Norm Theory) and willingness (as part of the Prototype Willingness Model) contributed to explaining the intent to reduce consumption, while willingness was also associated with behaviour.

Automated summary

Reducing heating-related energy consumption is crucial in Europe, where it occupies a significant portion of domestic energy usage. Factors such as perceived behavioral control, subjective norms, attitudes, environmental concern, personal moral norms, and willingness influence the intent to reduce consumption. This study used three theoretical frameworks and a sample of 3098 people from 29 European countries to analyze these influences and found that attitudes, environmental concern, personal moral norms, and willingness are significant predictors of intent and behavior to reduce consumption.
