What if we had a plan to build nuclear to replace coal in the US? Standardize on one type of nuke, maybe use the SMR approach, and for each new nuke, shutter a similar set of coal plants producing the same amount of power.
Clearly, if the above projections are close to right, we'll still have a large amount of coal in 2050. It sounds nice to say wind and solar of course, but you have to face reality and the numbers at some point.
