That's only your interpretation. The real reason is stupid overreaction to Fukushima. Otherwise Merkel would not overturn the phaseout decision in the first place.
When someone says "nuclear waste" people stop thinking rationally. Did someone actually die because it was not stored properly? All those claims how dangerous it is sound hollow unless you can point out some actual harm (as in, measurable health consequences, not a small radioactivity release causing stupid people to shit their pants).
So there is no place in Germany were we could safely store nuclear waste at all.
That's some kind of joke. There are plenty of places, but the real problem is that the government is fixated on the "metal can in salt" method, which has been proven inadequate by experience. It is not the only method in existence; for instance, the Swiss method uses metal containers in clay backfill buried in granite rock. The problem is that the extremely high concentration of anti-nuclear clowns in Germany is preventing any change from happening.
any politician will fight tooth and nail against a mine in his district.
That's another example of hysteria.
At the same time Germany tries to increase the amount of renewable energy and is quite successful.
For the amount it already invested in renewable energy subsidies, it got back less than 1% of the electricity supply, while an equivalent amount of money spent on new nuclear reactors could completely decarbonize power generation. How wise.
