The problem is that you can't extrapolate from countries that already have nuclear power plants to those that would need to start building them now.

If you start planning one now, it will be maybe done in 15 years and billions over budget. And in the mean-time nothing changes and business continues as usual.

If you take the same money and start building wind, solar, geothermal and battery storage you get an immediate effect and the result is more sustainable as well.
