> stringing HVDC interconnects

Agree that this solves many of the same problems as storage (as does overbuilding).

The PR problem with renewables is that the solutions are invariably cognitively complicated and multifactorial. The solution is going to be some kind of optimized result that mixes various storage forms, HVDC interconnects, overbuilding, and diversifying with solar and wind, and the exact nature of the solution is going to vary by geography.

It's just a hopelessly difficult communication challenge. If so many HN people can't grasp these concepts and jump to provably incorrect catchphrases like "storage is too expensive", then what hope is there for the general public.

People on HN don't generally realize that energy has pretty much always been a mix and that adding new energy sources with different availability, slew rates (both up and down, and not necessarily symmetrical), cost, peak capability, base load capability and so on is a well understood problem that markets know perfectly well how to deal with.

Then there is the 'cool' factor ascribed to some solutions, an element of hope that a favorite technology will one day power the planet and all kinds of unrealistic assumptions about what is and what isn't technically, socially and economically possible. You are right that this is a difficult communications challenge but the level at which the discourse takes place is well below the minimum standards for taking part in such a debate.

We're talking about very simple basic and factual knowledge here we are still very far away from the complexity of say the 15 minute ahead market, balancing and long term cost projections of a particular technology, we are more in outright disinformation and denialism territory.
