Here would be the outline sketch of a "PLAN", in part.
Goal: To replace nearly every coal fired generating plant in the US by 2035.
Problem: Many of these plants have sunk capital not yet amortized, e.g., it cost money to shut them down, and more money to replace them.
Approach: Add a "carbon tax" or whatever to coal to raise revenue devoted to this aim. It wouldn't be all that high I suspect.
The newer coal fired plants would get "paid off" with said tax, the older one would get replaced normally.
Replacement would be with nuclear, NG, wind, solar, whatever, at the choice of the utility and how they can manage intermittent power (or not).
Benefit: No more coal burning gases in our air locally, reduction in CO2 emissions, impact in global warming would be 0.001°C by 2050, more or less.
