In recent years, interest in the socio-political dimensions of the energy transition has grown in the social sciences. In particular, energy communities – coalitions of public and private actors who cooperate with the aim of producing, consuming and exchanging energy locally through the networking or collective construction of facilities – are attracting attention for the social potentials that reside in the community dimension with which energy is treated, cha from a commodity be- comes a common or public good. The article attempts to reflect on the different meanings that the concept of community takes on in this particular case, highligh- ting the difficulties of unambiguously defining what community is in energy com- munities and how there are policy perspectives yet to be explored.
