Actually you do not need nuclear for this. The problem is not nuclear here but to that Germany messed up setting up a fiscal mechanism trying to boost renewables (by introducing the so called EEG Umlage). The problem is that electricity (even green) was more expensive than it needs to be (particularly compared to gas) and the incentives were fading to invest into renewables. Nuclear power is no option in German simply because we could not reach any national consensus about the waste which would be a prerequisite.
Apparently Germans have no problem with huge quantities of unconfined waste from coal, but tiny quantities of confined waste from nuclear fission(which can be recycled) is the concern? This is not rational.
France uses a lot of electricity for heating and it’s not going great it would seem, since a lot of their nuclear power-plants are down for maintenance.
