I have gone back and forth between polar extremes on this question over the past decade. On the one hand, nuclear accidents and waste disposal problems pose risks so great we shouldn’t even contemplate them, not even for a moment. On the other hand, continuing to burn fossils sets us on a course toward continued environmental destruction and unchecked climate change.
Recently a group of environmental scientists delivered a public letter encouraging environmentalists to start taking nuclear seriously.
The reality is that renewables (wind and solar) can’t begin to scale to match the amount of energy we are using / will need in the future. And:
“Quantitative analyses show that the risks associated with the expanded use of nuclear energy are orders of magnitude smaller than the risks associated with fossil fuels. No energy system is without downsides. We ask only that energy system decisions be based on facts, and not on emotions and biases that do not apply to 21st century nuclear technology.”
Fukushima freaks us out, as it should. But Fukushima also represents a completely antiquated mode of nuke plant construction. Future plants will operate very differently, with a native tendency to shut down, not melt down.
Damned if we do, damned if we don’t?
