The law of renewable energies has always been subject to change. Together with the Scandinavian Institute for Maritime Law of the University of Oslo, the Berlin Institute for Energy and Regulatory Law has brought together energy law experts from Great Britain, Norway, Finland and Germany in order to exchange their ideas and perspectives. In 2013 and 2014, the ECJ specified the limits on national support schemes, and the European Commission issued its guidelines on state aid for environmental protection and energy. In an inspiring workshop, these and other important developments regarding renewable energies in the EU and the European Economic Area were discussed. This volume presents various contributions which inform about the conducted debates and encourage further research.
