An unrealized desire: what slows the implementation of energy communities in Catalonia?

The transition to a sustainable energy model requires a broad social consensus to succeed. However, there is currently limited research on the factors influencing individual acceptance of specific energy transition tools, such as Energy Communities (ECs), a gap this paper aims to address. Specifically, we examine whether the determinants of current willingness to join ECs are the same as those influencing future willingness. This question is particularly relevant, as some individuals delay their participation in pro-environmental actions in anticipation of better future conditions, a behaviour that ultimately slows the energy transition. Using survey data from 1840 individuals in Catalonia (Spain), our findings reveal that the same factors do not necessarily shape current and future intentions to join ECs. This insight suggests the need for policy measures that address current dissatisfaction with ECs and promote future acceptance. • This paper analyses the determinants of current/future willingness to join Energy Communities. • Proximity to an existing EC is associated with increased willingness to join. • Knowledge of climate regulation has a delayed impact, influencing mainly future willingness. • Individual characteristics (age and gender) also matter (noticeably for future willingness). • Existing EC members report lower future willingness.
