At the price of continuing tensions in society and politics. NPP weren't taken down just for fun, that was a long time coming. An NPP based energy policy wouldn't have stopped building new nuclear power plants in 1989: nuclear power never provided more than 1/3 of the electricity consumption of the country and unlike France, there was never a push to go all in, e.g. by promoting electrically powered domestic heating.
The real issue is that, even though renewables saw a pretty good growth, the renewables side of the plan was to push it even harder (and expand the transmission network, and establish storage) and that fell through once a government took over which didn't care for that all.
Those plans are 25 years old now (the Social-Democrat/Green coalition was formed in 1998 and set out to implement the transition from the start) and the south is still not properly connected to the wind power resources in the north.
Germany would have had to go all-in with nuclear (and build it out by a factor of 6 or so, to also replace avoidable uses of fossils like domestic heating) or it would have had to go all-in with renewables. Instead it stumbled around indecisively.
