The dominant model of energy infrastructure has historically been conceived as very centralized,with hardly any citizen involvement in energy production. Yet,an increasing number of scholars,citizens and policy-makers advocate the transition towards a more decentralized configuration,involving geographically dispersed and small-scale generation units located close to consumers[1].Decentralized system are said to present several advantages over centralized ones, including reduced costs for transmission and distribution systems, reduced grid power losses, more efficent data management systems and a larger share of zero-carbon technologies[2].In turn, this configuration requires an active role from energy users, the latter becoming themselves "prosumers" or coproviders of energy services[3].In this context,it is thus meaningful to study the factors likely to foster citizen participation. Communtity energy projects,i.e.,formal or informal citizen-led initiatives which propose collaborative solutions on a local basic to facilitate the development of sustainable energy technologies,may have an important role to play in this respect.
