Absolutely, there are issues. I was mostly commenting on the GPs "they are never going to be viable but for a small portion of our energy needs". They are viable already, for substantial parts of our load.

And you put your finger straight on one of the largest sources of trouble for the US - the existing grid. That's why I believe the way forward is decentralized power. Cut out the grid. Generate and consume very locally.

There are still many issues that need to be solved there, storage being probably the large one. But I'm more hopeful about that than reforming the US grid with its entrenched players.
