Clean energy for EU islands

Community wind turbines in Aero, Denmark

  • 27 May 2020

Ærø is one of the Danish Baltic Sea islands. In 1981 the  island’s community established the Ærø Energy and  Environment Office, which took the role of a local  intermediary in the process of developing a community- owned wind farm. Only inhabitants or companies on the island can buy shares. A bidding process ensured an  inclusive character, selling to those inhabitants who  wanted to buy a small number of shares before opening to those who wanted to invest a larger amount of money. Local banks contributed to this inclusive approach by  providing bank loans to citizens. 



The 6 wind turbines on Ærø are owned by 650 local shareholders (more than 10% of the inhabitants  on the island) and a local fund, which invests part of its returns into local community projects. The wind power project paved the way for a number of other renewable energy projects on the island, including three solar district heating plants and the world’s first all electric ferry project of its size.  Today, over 55% of the island‘s total energy comes from wind, solar, and biomass, and Ærø aims  to run 100% on renewables by 2025.
