             | 70% inference. And adoption is rising from month to month.

             | This is a good point. Another point is that the better
             | models get, the less wasted tokens there will be on
             | unproductive token generation for answers that are wrong in
             | some way. Better answers might lead to increased demand of
             | course. But less waste is not a bad thing in itself. And
             | improved quality of the answers has other economical
             | advantages.
             | 
             | My view is that increased energy demand is not necessarily
             | a bad thing in itself. First, it's by no means the dominant
             | source of such demand, other things (transport, shipping,
             | heating, etc.) outrank it; so a little bit of pressure from
             | AI won't move the needle too much. Our main problem remains
             | the same: too much CO2 being emitted. Second, meeting
             | increased demand is typically done with renewables these
             | days. Not because it's nice to do so but because it's cheap
             | to do so. That's why renewables are popular in places like
             | Texas. They don't care about the planet there. But they
             | love cheap energy. And the more cheap, clean power we bring
             | online, the worse expensive dirty power actually looks.
             | 
             | Increased demand leads to mostly new clean generation and
             | increased pressure to deprecate dirty expensive generation.
             | That's why coal is all but gone from most energy markets.
             | That has nothing to do with how dirty it is and everything
             | to do with how expensive it is. Gas based generation is
             | heading the same direction. Any investment in such
             | generation should be considered as very risky.
             | 
             | Short term of course you get some weird behavior like data
             | centers being powered by gas turbines. Not because it's
             | cheap but because it's easy and quick. Long term, a cost
             | optimization would be getting rid of the gas generators.
             | And with inference increasingly becoming the main thing in
             | terms of energy and tokens, energy also becomes the main
             | differentiator for profitability of AI services. Which
             | again points at using cheap renewables to maximize profit.
             | The winners in this market will be working on efficiency.
             | And part of that is energy efficiency. Because that and the
             | hardware is the main cost involved here.

         | 
         | All serious, viable plans for decarbonization include a massive
         | increase in electricity consumption, due to electrification of
         | transportation, industrial processes, etc, along with an
         | increase in renewable energy production. This isn't new, but AI
         | datacenters are a very large net new single user of
         | electricity.
         | 
         | If the amount of money already poured into AI had gone into the
         | rollout of clean energy infrastructure, we wouldn't even be
         | having this conversation, but here we are.
         | 
         | It makes perfect sense from a policy perspective, given that
         | there are a small number of players in this space with more
         | resources than most governments, to piggyback on this wave of
         | infrastructure buildout.
         | 
         | It also makes plenty of financial sense. Initial capex for
         | adding clean energy generation is high, but given both the high
         | electricity usage of AI datacenters, and the long-term impact
         | on the grid that _someone_ will eventually have to pay for,
         | companies deploying AI infrastructure would be smart to use the
         | huge amount of capital at their disposal to generate their own
         | electricity.
         | 
         | It's also, from a deployment standpoint, pretty straightforward
         | -- we're talking about massive, rectangular, warehouse-like
         | buildings with flat roofs. We should have already mandated that
         | all such buildings be covered in solar panels with on-site
         | storage, at a minimum.

         | I agree that in general, if the goal is to limit CO2 emissions
         | and use renewable sources of energy, we ought not to focus on
         | AI first, because it is dwarfed by many other things that we
         | take for granted today. My canonical example I give folks is
         | that the latte they order every day from Starbucks involves
         | substantially more energy and water use than most uses of
         | ChatGPT on a daily basis.
         | 
         | But as we move to digitize more and more of this world, and now
         | create automated cognitive labor, we should start with the
         | right foundations. I'd rather we not try to disentangle
         | critical AI infrastructure from coal power plants, and I'd
         | rather we try to limit the compute available to workloads in
         | ways that encourage people to use the tech actually befitting
         | of their use case rather than throw it all into the most
         | expensive model every time.

         | Well put, but I think it's important to bring the analysis one

         | Rome, business meetings, scientific conferences, and other
         | perceived-to-be-unalienable rights) are punching way above

         | Air conditioning for example would be a good place to save
         | energy, as the world wide energy consumption is a multiple of
         | AI's consumption. But climate change will push the need (not
