Yeah, renewables have gotten a lot cheaper. They weren't viable, but now they are, and waiting is a sunk cost.

I think it's unconscionable that we chose to emit ~20 gigatons of CO2 instead of pushing nuclear from 20% of our electric supply to 100% -- we would be there today if we had just kept up the pace -- but what's done is done. We killed nuclear and waited for renewables to become viable. We paid the price. The CO2 is in the air. Now we can move forward.
