Greece and Cyprus are particularly vulnerable to climate change due to a mix of geographical, environmental and socio-economic factors. The ecological crisis exacerbates existing inequalities, with vulnerable groups - such as those marginalised by gender, age, income or race - bearing the brunt of its effects. Within the framework of feminist climate and energy politics, understood as a set of emancipatory approaches that widen people's access to essential services, a key tool to be discussed here is energy communities. Energy communities offer an opportunity to increase citizen participation in the energy transition, while ensuring that social groups facing structural vulnerability are included.
