The negative prices indicate instability in the whole energy system, that’s not necessarily a capitalism thing. Don’t get me wrong I hate capitalism and love sun and wind energy, but many people are ignorant about the fluctuations and the fact that energy storage is not a solved problem right now.

That isn’t the limitation though, it’s the consequence. The phrasing of the tweet is extremely memable, but thinking about it for 5 seconds should make you realize that negative prices mean they REALLY need to get rid of it. Because having too much energy in the grid is a problem.
