This report provides policy recommendations for three levels of decision-making groups - individual consumers, collective decision-making units, and policymakers/energy providers - regarding smart energy technology, electric mobility, and buildings. It finds that one-size-fits-all policies will not work due to differences between countries. Recommendations include regulations, support schemes, empowering local governance, and encouraging public procurement. While groups have distinct contexts, their actions cannot be treated in isolation. A multifaceted approach is needed to reach climate and energy targets, combining regulations, risk reduction, and knowledge sharing.
