I think a nuclear future is definitely greener than our gas, oil and coal based present. But wouldn’t a renewable energy future be much, much better than either?

I’ve heard the argument that nuclear can provide a consistent base, which I suppose is true. But you need a way to flex the remaining renewables you have still, since nuclear can’t turn up and down as easily as fossil fuels. Which to me says, nuclear + renewables requires the energy-flexing mechanisms that would also make pure renewable possible.

So my take is, I think it might help reduce warming somewhat, but really we should be aiming for 100% renewables.
