SetENERGY explores how Socio-Ecological Energy Communities (SEECs) can strengthen the focus on social aspects in the energy transition by engaging a more diverse population. We map relevant cases, identify and test predictors for energy donation, engage energy-poor households and stakeholders in co-creation and bring findings and recommendations to energy communities, the wider public, and policy makers. Our research questions are: What are the drivers and barriers for both donors and recipients to engage in SEECs? To what extent can SEECs empower energy poor households in the energy transition and what are their limitations? Which policy measures and practical aspects are needed to foster the implementation of SEECs in Austria? We use a mixed-method approach combining desk research and literature review, qualitative interviews with stakeholders from energy communities and related institutions, a survey with energy prosumers, a field experiment testing solutions to facilitate the expansion of SEECs, and Social Labs with members of SEECs, which are a participatory co-creation process stemming from action research.
