Especially in regards to Germany we would not have the current problem if we had decided or acted differently. Maybe pro-nuclear, maybe more building alternatives.
For now you are right, we won't be able to activate anything nuclear till the winter.
The funny thing is, the same people arguing against nuclear power (with mostly ridiculously unscientific arguments against all statistics) will be the ones complaining about the situation and that politics should save us all.
I am very interested in the pro/contra nuclear discussion and the more i know about it, the more our current situation saddens me.
