Yergin sounds like he still thinks wind 'farms' and battery 'backup' will be part of a "transition", but I like your take better - that it's dead already in the US - plus my take - that it can't survive much longer in Europe either.

Intermittent solar and wind require some form of backup to "fill in the blanks" when they are unavailable. As long as that is the case, solar and wind are redundant capacity and redundancy costs. Storage might eliminate the redundancy but at a monumental cost. DEFRs might eventually provide the required backup, but solar and wind would still be redundant and thus unnecessary.
