The European energy transition has hardly made headlines since the beginning of the COVID-19 pandemic. Still, the transformation of energy systems in Europe remains one of the most important challenges and opportunities. The project Energiewende Twinning Towns, which was funded by the German Federal Foreign Office and carried out by the Agency for Renewable Energy in collaboration with the Humboldt-Viadrina Goverance Platform, demonstrates how the transformation can be advanced concretely at the municipal level. With a final digital conference, the project is saying goodbye for the time being to the city pairs from Germany, Ireland, Greece, the Netherlands and Poland.
