So I think we basically agree ... except for the interest in building more fission nuclear plants. ; ) You've suggested it's close to zero carbon by selecting

  I won't deny that there is some regional variability in the carbon intensity of energy systems. As mentioned elsewhere, France uses nuclear power to run nuclear fuel enrichment and reprocessing services, where some places in the US use coal. Thus, nuclear in France is lower-carbon than nuclear in the USA. Given that increasing nuclear's share would proportionally decrease nuclear's carbon intensity, and that nuclear at worst is ~10x less carbon-intense than the current average energy mix, I say it's OK to use the median values from that table for basic energy system comparison purposes. Note also that utility PV max is 180, and hydro max is 2200 (2x coal's median!) because of uncertainties in biogenic methane. So if we compare the max of each in this table, we make roughly the same energy system decisions as if we compare the median (again, except for hydro, which we'd have to phase out rapidly if that max is realistic).
