Reframes the energy transition as a societal project that needs active citizens, not just policies and hardware. Introduces 'energy citizenship' — citizens moving from passive consumers to co-producers, co-owners and co-decision-makers — and grounds it in the EU Clean Energy Package and the fact that households and transport together represent roughly 70% of European energy use. Builds a three-pillar picture of what citizens can actually do: behavioural change (savings through insulation, efficient appliances, mobility choices), local generation and participation in collective projects (prosumers, energy cooperatives, neighbourhood batteries), and engagement with policy and community (decision-making, education, peer learning). Closes with a careful look at the barriers — physical/financial preconditions, social and organisational dynamics, cultural and psychological barriers (powerlessness, energy illiteracy), and institutional questions of inclusion and fairness — illustrated with the Yellow Vests and the Swedish Bensinupproret.
