> The co2 balance of building nuclear power plants will only amortize when we already hit 1,5°C warming and it is questionable if it helps at all considering the unknowns about operating periods and other influences.
This is why it’s sad to decommission existing plants, but I don’t think there’s any legitimate question as to whether nuclear is harmful. It’s a pretty well-understood quantity, but I’m not sure which “factors” you’re describing.
> Overall if we just look at Germany it wouldn't even matter, the nation is too small, it wouldn't even make a dent. It is still necessary to reduce emissions, but if you zero them all, it would be less than 2% of overall world wide emissions, even if it is on place 6. Not for long though and it will be completely dwarfed by the US, China and India.
No Germany alone won’t make a dent directly, but it can model leadership. It’s a lot easier for other countries to get on board when someone has paved the way.
