Held over two days at Case Esment near Palma, Mallorca, the Clean energy for EU islands forum 2026 brought together 133 participants to take stock of progress and define the next steps for decarbonising Europe’s islands.

While islands are particularly vulnerable to climate change, they enjoy a naturally high potential of renewable energy sources to harness. Many islands have abundant renewable energy potential, which can be tapped to lead decarbonisation. However, access to reliable, clean and competitive sources of energy remains a main concern of island communities in the EU. Although it is often technically and financially possible to develop renewable energy projects on islands, legal and regulatory frameworks, whether EU, national, regional or local, are not always fitfor purpose.

Day 2 focusing on implementation, integrated planning and island-tailored policyThe second day of the Clean energy for EU islands forum 2026 in Mallorca turned attention from overarching governance questions to the practical conditions needed to deliver island decarbonisation on the ground. Across breakout sessions, panel discussions and the closing plenary, participants explored how integrated planning, stronger local delivery structures and closer alignment between island, national and European actors can help translate ambitious targets into concrete action.

Day 1 highlights the need for stronger governance and stakeholder alignmentThe first day of the Clean energy for EU islands forum 2026 in Mallorca focused on one central message: decarbonising Europe’s islands requires stronger alignment across all levels of governance and closer cooperation between the many actors involved in the transition.

On 22 September 2017, the European Commission, together with high-level representatives from EU Member States and island regions, hosted the Inaugural Clean Energy for EU Islands Forum in Chania, Crete (Greece).

This video, submitted for the Clean energy for EU islands Call for Videos, by the Estonian Islands Energy Agency describes the challenges faced by Estonian Islands when it comes to energy generation and the clean energy transition. It emphasises the importance of the transition to clean energy sources for these islands and mentions various ways of achieving cheaper and cleaner energy supply for the islands.

This video, submitted for the Clean energy for EU islands Call for Videos, showcases how the cooperative, Energia Bonita, was established after the 2021 volcanic eruption on La Palma, when residents began reflecting not only on rebuilding infrastructure but also on how energy is produced and managed locally.Stakeholders describe how the cooperative generates electricity from solar photovoltaic installations distributed across the island and supplies this energy directly to its members.

This report presents a roadmap for decarbonising public buildings on the island of Korčula, Croatia. Based on energy certificates and audits, energy consumption data was analysed for 15 buildings. The findings indicate that heating energy consumption varies between 55.97 and 253.5 kWh/m² per year, with an average of approximately 116.6 kWh/m² per year. Two buildings, Gradska Uprava Grad and Djećji vrtić Korčula, underwent a comprehensive analysis to identify opportunities for improvement and enhance their operational efficiency and sustainability.

This technical report has been prepared to present the design assumptions and technical solution for an investment project involving a Photovoltaic (PV) Carport installation on Korčula Island. The project considered in this report is referred to as Korčula Parking Lot 2. It is located near the town of Korčula, Croatia. This is a Carport PV power plant, with a total peak power of 203.1 kWp. The PV modules are installed on structures with an inclination of 10° on the Carport plant, and oriented 13° from south.
