The Windvogel is a cooperative association whose goal is the realisation and generation of renewable energy. The Windvogel contributes to this through the realisation of new wind turbines and the purchasing and operating of existing turbines and solar PV installations. Founded in 1991 the cooperation now has over 2800 members in the Netherlands. It has five turbines with a total capacity of 3.7 MW and there are several projects under development. The Windvogel also supports other local wind and solar energy initiatives with advice and assistance with realisation, from concept to commissioning. Windvogel membership for life costs just fifty Euros, once, for life.
