This is coming from a group that does analysis on the semiconductor and cloud industries and provided very expensive access to their models and info. They are the citation.

Even if that’s true, that seems like a putrid number, no?

Assuming a single 1GW the data center runs 24/7 365, it’s consuming 8.76 TwH per year. Only being able to generate $10-$12B in revenue (not profit) per year while consuming as much electricity as the entire state of Hawaii (1.5M people) seems awful.

If you do the math, that's $10-$12 per watt year. There's approx 24×365.25=8766 hours in a year, so assuming that the datacenters would be running 24×7, that boils down to $1.14 to $1.37 in revenue per kWh. That's not a bad deal if power really is a major part of the expense.

“Could”, sure... and I “could” fly if I strapped a jet engine to my ass
