Ever since reading Ryan Holiday's book, Trust Me, I'm Lying: Confessions of a Media Manipulator, popular controversies like this always make me wonder who benefits from their continued discussion.
Every time someone talks about how AI is using energy, that's free, viral publicity advertising AI, keeping us obsessed with talking about it for one reason or another. The controversy makes it stickier in our brains. It makes it feel relevant even if you aren't using the product yet.
And yes, when done correctly, a leading figure in AI acknowledging the allegation and responding to it helps to further our obsession with the idea. The reassurance might not be to assuage, but rather to keep us engaged.
I don't think he'd outright lie, but possibly the calculation is ... stretched ... to fit the narrative.
Let's call it a small pizza, then :)
Meanwhile your idle desktop PC and monitor are pulling 20-100W each.
People tend to forget that doing the work the old fashioned way uses energy too. Presumably for a longer time for equivalent results.
The average ChatGPT query uses 0.34 Wh (0.12 kJ, 0.3kcal) and 0.32ml of water.
This means if you ask it one question every two minutes, you're using about as much energy as a 10W LED lightbulb.
If you use it 5000 times, you'll waste the energy of a medium-sized pizza, and water amount equivalent to how much you'd need to wash your hands after that pizza.
