I also have the real cost of building a new reactor in mind when thinking of Germany getting back into nuclear.

Is the economic sense really a good argument? That implies that a privatized group needs to make profit, all external effects paid for, and still be able to give you a good price.

If the government builds this with the aim of supplying cheap energy to people and industry with no profit margin then does this all matter?

The government spends large sums of money on this that and the other and the return of investment on these things are obscure or manifest over longer time horizons like building infrastructure etc

I am not against renewables, just to say that. I could not have too many windmills etc and the arguments against them are unconvincing.

So yes forgiving and all that. Here are the steps: 1 Putin removes his troops from the occupied territories 2 he apologizes 3 maybe someone forgives him.
