Seems like a combination of the cyber truck being wildly inefficient due to being incredibly heavy and bazinga shaped and supercharger stations charging double or more the usual residential rate per kWh.
It costs money to run the diesel generator powering the charging station. A year ago there was a study on what it would require to have a typical truck stop for Tesla's electric semis. A 30MW generating capacity, with even a basic charging station using as much power as a town of 5000 people: https://www.bloomberg.com/news/articles/2022-11-14/tesla-s-electric-semis-are-coming-and-trucks-stops-aren-t-ready
the vast majority of them are grid-only. Some large stations apparently have used diesel supplementary power for when lots of cars are charging at the same time in the past, and there's no way to be 100% sure they don't still do it, but I have seen no evidence they do. It's still dumb they did that like, ever, but not as bad as he made it out to be
It's an energy density thing, it takes a shitload of electricity to charge something huge to run very far, that's why petrol has such a grip on things. In a rational system you could create some sort of predictable, low-friction road where economies of scale could let you transport large amounts of freight and people quickly with less power, but car-brain hasn't come up with a solution yet. You either need massive capacity to accommodate all the electric trucks on demand, or a long wait to let them charge at a manageable rate.
its a misconception. They did do so at one location that I've seen citations for, a very large installation in socal that presumably needed more power than the grid could provide without upgraded infrastructure nearby, and supposedly they upgraded that one and haven't done so in years.
The vast vast majority are definitely just running off the grid but someone seems to have started a rumor that all the big transformer cabinets around the stations are actually housing generators.
I was looking at the math for Cybertruck energy usage and it is shockingly (heh) egregious: Using the numbers provided in the post it takes like 3.5 days worth of the average USA household electric usage to haul that bloated doorstop 200 miles. And that's with all of the "round it for easy math" happening to go Tesla's way...
It's not unique to that particular bloated doorstop. By the screenshot's numbers it comes in at 533 Wh/mi which is toward the lower end of US EV efficiency but not the lowest. According to this chart that about matches the Chevy Silverado EV at 535 Wh/mi and the Hummer EV at 674 Wh/mi is even worse. Of course, more reasonably sized EVs are more like 200-300 Wh/mi.
Amerikkkan cars are just too fucking big and making them electric doesn't do a damn thing to fix that.
I'd expect that if you calculated the average amerikkkan household energy use (including fuel) instead of electricity, these monster EVs wouldn't be that outside the norm, because the average amerikkkan household owns an F150.
EDIT: and my electric unicycle takes about 44 Wh/mi.

Why the fuck are the charging stations running on diesel joke of a country joke of an electrical grid

They run diesel generators? Lol would be funny if cubertrucks are emitting more CO2 normal trucks.
