I don't think Germany is surrounded by countries that flagrantly pollute the environment.
What is more likely is that more power will be imported from France, which massively use nuclear energy (>75% of the national electricity production), and doesn't intend (so far) to move to something else.
It's inefficient to carry electricity over long distances, so I don't see Germany buying energy from say Ukraine. That said it seems that Poland is big on coal and crude oil...
My point exactly. From what I understand, reliance on Poland's (exceedingly dirty) coal-burning capacity is a big part of Germany's plan to wean itself off nuclear power.
