As part of the EU’s 30 by 2030 Clean energy for EU islands initiative, the island of Gotland took a significant step forward in its strategy for community engagement and participation. In collaboration with the Energy Academy of Samsø, Denmark, a practical workshop (08 April 2025) was held to explore effective methods of fostering local involvement in the energy transition.Organised by Energicentrum Gotland and led by sustainability expert Mr Sören Hermansen, the workshop took place in the village centre of Roma, just outside Visby.

Lambay is the largest island off the east coast of Ireland and lies just 20 km from the centre of Dublin and five km off the coast of Rush, North County Dublin. It is a Natural 2000 site and part of a Special Area of Conservation. The island is entirely off-grid and has been partly renewably powered since the 1970s. The island availed of an EU ERDF LEADER grant in 2023 to increase storage, wind and solar PV capacity and also convert to a three-phase system.  The current aim is to optimise the renewable generation through an intelligent grid system with heat pumps.

This report estimates the potential annual energy production by an in-pipe hydro plant on the island of La Palma, Spain. The Caldereta reservoir and its connected pipelines are considered for the plant's location. The expected energy production is calculated based on modelling work. The island transition team selected the Caldereta reservoir in the southern region of La Palma, Fuencaliente, for this study. Two pipelines, one downstream and one upstream, are of interest and connected to the Caldereta reservoir.

This report presents the results of the pre-feasibility assessment for repowering the Nasca Wind Farm, located on San Pietro Island (Sardinia, Italy). To assess the repowering of the existing wind farm, a total of 8 new possible configurations were considered, highlighting the benefits of higher tower heights.

This report explores the potential for integrating PV systems and BESS at Pantelleria Airport. Developing a hybrid PV-BESS plant at Pantelleria Airport represents a pivotal step toward achieving energy independence and sustainability on the island. Pantelleria can significantly reduce its reliance on imported fuels, lower greenhouse gas emissions, and stabilize energy costs.  Given its large, underutilised surfaces, the airport presents a strategic opportunity for a PV plant.

This report explores energy efficiency measures for traditional buildings in Ireland, focusing on the Aran Islands, which feature a rich portfolio of historic stone buildings. It highlights the European Union’s (EU) regulations and directives to improve energy efficiency and reduce carbon emissions, as well as Ireland’s national policy framework. Key retrofitting measures discussed in the report aim to improve thermal performance while preserving the external appearance of buildings in compliance with conservation regulations.

This report provides an in-depth assessment of wind energy development potential in Öland. It analyzes existing wind energy plans, technological advancements, land use constraints, and wind resource availability to identify priority areas for future wind power projects. First, the technical, cultural and environmental constraints for deploying wind farms are assessed, and a list of priority areas is defined.

This report presents a first technical and economic assessment of the possibility of introducing hydrogen-fuelled ferries for transporting passengers and vehicles between the islands of Giglio and Giannutri and the mainland.

This report aims to provide an overview of agricultural decarbonisation opportunities in Gotland. Targeted primarily at farmers and technology providers, it focuses on crops and livestock, excluding forestry and fisheries.

This study explores the feasibility of a community wind turbine in Oileán Chléire, Ireland. The project was initiated in 2022 by some members of the local community, who have already obtained a connection assessment from the local Distribution System Operator (DSO).
