Again, though, that's just not true. The hardware is well-understood and easily measured. Sure, there is slop in the measurement (how much of the fleet is using platform A vs. platform B). But those are comparatively small numbers. Sure, like you say, we might have a factor of two lurking in there (seems high, but I'll grant it).

But a factor of two wouldn't change any of the analysis! If the article said "60 TWh" instead, would that be any less horrifying? No, it wouldn't.
