           | 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!

           | 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.

             | 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.

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

         | isn't one of those situations where every little bit counts.
         | There are 2 or 3 things you can do to reduce your environmental
         | impact and not using chatbots isn't one of the things.

       | 
       | A very small model could run on device to automatically switch
       | and choose the right model based on the request. It would help
       | navigate the difficult naming of each model of each vendor for
       | sure.
