German Environmental Aid: Not even every tenth major German city is doing enough to expand solar power. Of all 82 major German cities, only Oldenburg, Paderborn, Regensburg, Neuss, Oberhausen, Gütersloh and Erlangen are on a very good path.
The bottom-placed Potsdam, Lübeck and Bremerhaven would have to increase their expansion rate by 350 percent in order to steer towards the 1.5 degree limit. DUH calls for a nationwide solar standard and a reduction in bureaucracy.
