And each toilet flush you make should also have a Co2 calculation which should go against your daily carbon allowance.

Spending drinking water for toilet flushes is indeed a problem. Perhaps not CO2 measurements directly, but informing people in general of how much high quality water is wasted on flushes alone will hopefully bring more momentum into more efficient flushing mechanism and introducing grey water systems to new and old buildings alike. Good idea!
people downvote your sarcasm, but if you do the calculations you're kinda right.

1Kg of Beef costs:

  - The energy equivalent of 60.000 ChatGPT queries.
  - The water equivalent of 50.000.000 ChatGPT queries.
Applied to their metric Mistral Large 2 used:

  - The water equivalent of 18.8 Tons of Beef.
  - The CO2 equivalent of 204 Tons of Beef.
France produces 3836 Tons of Beef per day,

and one large LLM per 6 months.

So yeah, maybe use ChatGPT to ask for vegan recipes.

People will try to blame everything else they can get a hold on before changing the stuff that really has an impact, if it means touching their lifestyle.

The LLMs are not the problem here.

Those are incredible stats. As a vegan who uses LLMs at work frequently, I would love to have the source as well :)

You got to do the calculations yourself though.
Wow, thanks. I’m even coming up with 500K chatGPT queries for the amount of energy consumed as a KG of beef, though I might have moved a decimal place somewhere - feel free to check my math :)

“average query uses about 0.34 watt-hours of energy” - or 0.00034MWH

Using this calculator: https://www.epa.gov/energy/greenhouse-gas-equivalencies-calc... - in my zip, 0.0002KG of CO2 per MWH. (Though, I suppose it depends more on the zip where they’re doing inference, however this translation didn’t seem to vary much when I tried other zips)

Then, 99.48KG/0.0002KG= 497,400 chatGPT queries worth of CO2 per KG of beef?

Thanks for sharing!

`0.00034MWH`should probably be kilo not mega, but I think you still did it correctly :D

I think I used Btu (thermal units) in my calculation, so I only calculated actual energy expenditure for my 60.000 queries result.

But you are right, a better metric might be to use CO2-equivalent, because cows emit a lot of methane, whereas chatbots don't.

99.48KG / 0.228kg/kq = 436,315 queries per kg of beef.

Yup checks out!

This is a good article on the subject:

He’s done some good followup articles as well:

The difference is that food is important and live-giving and LLMs are a very fancy magic 8-ball
You don't need beef, beef is a lifestyle choice.

I use LLMs to do all of my coding these days, it's certainly more essential for feeding me than beef.

Also a lifestyle choice
Yes but one with a much much much smaller impact as we just demonstrated.

This is exactly the kind of cognitive dissonance in people that I meant.

You literally see the math and go "but I like my meat, why should I give that up if you got your AI".

Because, as I just demonstrated, my AI takes a infinitesimal fraction of your meat.

It literally takes you only going vegan for a day to offset your entire AI usage of a year.

This is spot on because there can’t be two issues that exist simultaneously. There can only be one thing that wastes enormous amounts of energy and that thing is beef
Nothing stopping us to live the hermit life in the mountains. But here we are trying to get bits and bytes to write that JIRA ticket instead of us.
You could eat a few bites less of beef in one meal and that would be your equivalent AI use for a lifetime.
Where does a Youtube LetsPlay video fall into that calculation? My understanding is that a single watch of a video is orders of magnitude more than a day's active use of ChatGPT.
Toilets are already labeled with their usage rate.
I don’t flush my toilet, I Kildwick [0] but J-pd has a more interesting comparaison

This is a good point because being curious about energy usage is the same thing as advocating for an imaginary rule about energy usage
