Aye, that was the argument back when replacement was on the table. Now we need to build, and we need to build everything. All the wind, solar, and nuclear we can afford to build. I'd leave coal as a last resort, and oil is absolutely counter productive. We should probably avoid LNG plants too, with the possible exception of Norway.

Replacement was always a fantasy. The nuclear power plants that were operational should never have been shut down. This was a disastrous policy and was absolutely clear at the time.
