Yeah, it's a crazy decision resulting from "green groups'" radiophobia after Fukushima.
The government official estimated cost of shutting down all German nuclear plants is 55 billion Euros over the next decade. Although the (frankly more credible) 'unofficial' estimate puts the cost at 250 billion euros over the next decade.
Not to mention the fact it's resulted in their co2 emissions increasing in both 2015 and 2016 (https://www.cleanenergywire.org/factsheets/germanys-greenhouse-gas-emissions-and-climate-targets https://www.cleanenergywire.org/factsheets/germanys-greenhou...). This also means increased deaths from air pollution. The German environment ministry now predicts they will probably not make their 2020 co2 reductions targets.
So other than the enormous cost, increased co2 emissions, and needless human deaths, good policy.
EDIT: And as for the whole "let's just replace everything with wind and solar", I'm not sure people fully appreciate what will be involved. In Germany's case, on a monthly basis, their wind plants manage an average capacity factor of ~20% (std. dev. 7.65 percentage points) and their solar plants manage an average capacity factor of ~10% (std. dev. of 6.41 percentage points). They have had months where solar only managed a measly 2% cap factor and wind 11%.
So let's say demand is 1TW/hr per month. This means they need to build about 11 times that in nameplate solar capacity, or around 5-6 times that in nameplate wind. So you also need to build 11/6 times the transmission infrastructure. And even then you will still have random blackouts due to the high variance in generation, so you also have to spend a bunch of money on grid-level storage.
