The real question is what the hell VISA is doing that one of their transactions requires even a tiny fraction of the work that goes into the mass hashing of Bitcoin.

VISA has to maintain its data centers. They're working on becoming more energy efficient, but it's a long and involved process. [0] On top of that, there's also the energy required to run the PoS terminals, I'm not sure if that was factored into the equation though because that burden is shifted to vendors.

Does a Bitcoin PoS terminal require less energy or are they about the same?

That's not "the real question" at all, and to frame it as such smacks of whataboutism.

High-availability data centers use power. We understand this. They also have meaningful outputs that Bitcoin struggles to demonstrate on its own.
