Energy communities can potentially advance just transitions towards low-carbon systems by devolving energy production and consumption to local scales. During vibrant debates on evolving energy geographies for more than a decade, human geographers have engaged with conceptualization and emergent models of energy communities in generative ways. We argue for a research agenda where these understandings of space, place and scale enhance research on energy communities. Three points hold particular importance and relevance for this agenda: (a) Pluralising understandings of energy communities, (b) Spatializing perspectives on the potential of energy communities to advance just transitions, and (c) Contextually situating technological-energy innovation strategies.
