Not that impressive when they started a green revolution (Grünewende) in the late 90s. And during all this and specially recently people had pretty high energy prices. And during all this time huge amount of coal dust is still spread over central Europe. You can most certainly change things faster then that. First of all, not turning of almost 20% of electricity supply off simply because of some delusional misconception about nuclear energy. My own quite conservative calculation show that they could have finished this whole transformation by now for far less money if they had simply replicated what France did decades earlier.
