Politics in the British Isles projects amongst the various countries in the Isles have been undertaken, often around infrastructure and energy. For example, the governments of Ireland, Scotland, and Northern Ireland are collaborating on the ISLES project, which will facilitate the development of offshore renewable energy sources, such as wind, wave and tidal energy, and renewable energy trade between Scotland, Republic of Ireland and Northern Ireland. Through the auspices of the British-Irish council, Ministers from the UK, Ireland, Isle of Man and the Channel Islands have agreed to work on energy cooperation and development through what is called the All Islands Approach (AIA), facilitating closer
