The Clean energy for EU islands secretariat, an initiative of the European Commission, is the central platform for the clean energy transition of the more than 2,200 inhabited European islands. The Islands secretariat’s website acts as a centre to showcase best island practices as well as the islands and island groups taking part in the 30 for 2030 call. It informs about policy and regulatory issues for Europe’s island communities and provides dedicated advice for capacity building and clean energy transitioning.
