The problem has been big bang policy-making. There is no inherent issue with renewable vs non-renewable, the only thing that matters is can you get energy at a cost that is economic...that is the purpose of the system we have. The problem has been created by policy-makers who want to go very quickly in one direction without regard for any other goal than increasing the share of renewables.
I think the only things most people are missing is the that a) renewable energy production has skyrocketed in the last five years specifically, with no slowdown in sight and b) as of just the last couple years we are seeing a similar boom in industrial battery installation that is starting to making the chorus of "but the sun doesn't shine at night!" sound old fashioned.
I suspect this is an issue that looks worse in 'intuitive' foresight but not so bad in educated retrospective but we will not know until we pass through that point. I am but an armchair "expert" on this. Usually when something like this comes up, 15 people who know better than me will highlight something I was not aware of.
