Yeah, total energy according to 2023 EIA figures and to be clear what I meant to say was that tripling nuclear would mean adding an amount equal to 20% of the current total of fossil fuels. The higher efficiency of e.g. electric transport does make some difference there, but all the fossil fuel use does need replacing somehow (the article was explicitly talking about “net zero” goals) and in optimistic scenarios that’s in large part through greatly increased electric generation.
My first guess was that you were referring to climate change. Doesn’t make much difference. They’re both problems which the government does not have the power to solve by itself, but nonetheless could do a much better job of responding to.
