> It’s also from focused efforts to close coal plants,

For many years coal has been more expensive than solar and wind. That's why utilities are decommissioning the plants.

It’s true, and the strategy of climate activists in the early 2000s and 2010s was to do everything they could to make coal and other fossil fuels as expensive as possible: by reducing access to capital, increasing the cost of legal and regulatory hurdles, sometime delaying projects through physical blockades, etc etc.
