> FWIW there was a huge surge in energy costs following the war in Ukraine (due to the reduction in supply of Russian gas)
And due to the fact that they decided to shut down the last nuclear power plants directly after that, which further reduced supply and until today I consider this one of the most stupid political decisions ever made.
I think the 4.1 percent that nuclear was providing was not having the impact you are assuming. Also the amount of energy produced by natural gas and renewables more than offset the cost of nuclear.
