> lets just ignore the waste and emissions that it generates at all other fronts (building the plant and materials for it, mining and processing of the fuel, processing and storage of spend fuel, disassembly of the plant)

Because of course wind turbines just appear by themselves and don’t need steel, concrete, composites, and, well, turbines (with the associated material sourcing and recycling issues). And solar panels are just picked on trees and do not need any fabrication.

The overall carbon impact for the different energy sources are well known. Solar is slightly worse and nuclear and wind are even. All three are orders of magnitude better than any fossil fuel.
