In line with the EU's Clean Energy Package goals, the EU-funded RENergetic project empowers people ' engaging them from the beginning ' with a higher level of control over the energy infrastructure surrounding them. RENergetic demonstrates that urban energy islands increase the share of renewables in local areas and the energy efficiency of the local energy systems. To reach this endeavour, innovative technologies are considered e.g. AI-based smart control algorithms and digital twins creation. RENergetic integrates electricity, heat and waste vectors in three energy islands: New Docks in Ghent, Warta Campus in Poznan and San Raffaele Hospital and Research campus in Segrate-Milan. Beyond RENergetic, the impact of urban energy islands is ensured by considering technical, socio-economic and legal viability, while safe-guarding economic viability.
