A German court has rejected an appeal against offshore wind stations in the North Sea near the islands of Borkum and Wangerooge. Island residents filing the appeal argued tourists would dislike turbines visible from shore and that possible collisions of ships with turbines would result in beach pollution. The Oldenburg administrative court says the appeal was inadmissible as the projects in question, the 90 MW Nordergründe project and the 264 MW Riffgat project, are proposed for sites outside municipal boundaries. The court adds that assertions that tourism would be adversely affected were "not convincing" and that any risk of beach pollution would be attributable to ships rather than wind turbines. Energy firm EWE and developer Enova plan to start construction of the Riffgat project around 2011 and developer Energiekontor sees construction of the Nordergründe project starting in 2010 or 2011.
