>Solar power will not get a complex if nuclear is chosen instead.
I think we'll run out of economically extractable ore deposits of nuclear fuels a little before Sol goes supernova. Perhaps that's it.
Also, unless he edited, he said that Nuclear was "safe enough" not that it was the best option. Even if it were the best primary option I wouldn't want to rely on it exclusively; personally I consider that "renewable" sources are better. Fusion would appear to be the best if we can get it to work effectively but I'd still look to diversify to some extent.
