Look at almost any chart online comparing estimates of carbon footprint and you'll see wind and PV are well below nuclear, and they pay back within months.
Nuclear takes a decade to even start operating and by some estimates is worse than natural gas in carbon footprint. Uranium refinement and waste fuel processing take up a massive amount of resources.

Solar pays back its carbon footprint within months, whereas nuclear may very well have a footprint much larger than natural gas.
Look around. Do you see any utilities or investors building nuclear plants? No? Meanwhile wind and solar deployments are skyrocketing, both grid and small scale.
Do you think maybe the people running power grids and investing in power plants know a little bit more about this than HNers like yourself do?
