a human being uses about 1 gWh in a lifetime on average.

Training one model nowadays uses more than that. So the model also cost more to train than to raise a team member (possibly all three of them)

whoops, got the numbers wrong. 1gWh is how much electricity a person uses, not how much energy the body consumes.

That works out to about 72 years365 days2000 kcal = approx 61 gWh
