Instead the CO2 per capita in Germany is 2x the one in France. And France had built their reactors in the 70s for a modest price.
The "whole load more renewable energy" idea is peak wishful thinking and it's incredible people still buy it today.
Much of that $700B was spent in the 2000's and 2010's when renewable was more expensive than nuclear. But renewables are far cheaper than nuclear in the 2020's.
Germany has just over 250GW of installed capacity. [0] indicates peak power is 75GW. Replicating the Olkiluoto EPR build for 75GW of capacity would have cost perhaps 500B EUR.
[1] speculates about what would have happened if Germany had retained its nuclear power stations and performed a fleet build-out.

That study is laughably bad. To the point that they double counted all renewable investment.
