Yes, this argument gets repeated again and again and again, and when you ask about storage you never get a decent answer. And yet, the argument keeps getting repeated even by people who matter and make the decisions. When I started watching debates in the Dutch house of representatives I pretty much lost all hope. Of the 150 members, I'd say 145 are either unable or unwilling to think quantitatively and do simple napkin math. Not just regarding energy policy but in all areas. Yet they are verbally very strong, which makes the problem even worse. I suspect it's the same in most western countries.

If you think I'm exaggerating, remember when the Royal Statistical Society asked "if you spin a coin twice, what is the probability of getting two heads?" and 47% of Conservative MPs and 77% Labour MPs got the answer wrong. Many technical people cannot even fathom this, and tend to assume that people who cannot answer such questions must be severely mentally impaired in general. That is completely wrong; you have lots of people who are near geniuses verbally but incapable of or unwilling to do quantitative thinking.
