I blame Bavaria. If Germany had multiple price zones like other European countries instead of one giant one prices would plummet here in the north, while they'd explode in Bavaria. The state that does not want wind power, does want nuclear power, but already knows ahead of time that its geology (with lots of mountains and granite) is unsuitable for nuclear waste storage. Meanwhile, north German wind power and Scandinavian hydro dams complement each other perfectly. The Bavarians could do the same with the Austrians, they just don't. They want to eat cake and have it, too.
