"Defenders of the electric grid status quo have long argued that always-on baseload power generators like coal and nuclear plants are essential, and that variable renewables like wind and solar will remain bit players in power generation.

Or they aren’t reliable enough, so they require 100% backup from conventional power plants at all times.
