> As of this year, the cheapest wind and solar farms have a lower total cost than the marginal cost of the average nuclear plant.[1] That means that in many places, it is cheaper to immediately shut down the nuclear plants and direct the money that was spent on operating costs into construction of renewables.

Except that in this situation fossil fuel-based generators keep running.

We should be keeping nukes for as long as possible, and shutting down coal and gas first. The new renewable pick up the slack for coal/gas, and once all of the latter are gone then you start shutting down nuclear.
