... you don't have an argument against solar and wind energy generation.
For some reason lately, writers at Heartland Institute have been playing the "intermittent" card a lot lately. Like this today from Ronald Stein:
The Northwest has spoken loudly as the Benton Public Utility District (BPUD) has documented their actual battleground experiences with intermittent electricity from wind farms .... Kudos to this Washington state public utility for speaking up after seeing the costs and dangers of California’s experience with an overreliance on intermittent electricity from wind and solar. ... The Benton PUD believes it is reasonable to question whether continuing to favor investments in intermittent wind electricity and putting up roadblocks to the development of dispatchable natural-gas power plants is more about environmental virtue signaling than it is about serving the best interests of the citizens of Washington State.Emphases mine.
