    Nuclear power plants are expensive and take time to build, though. At the moment we're still burning way too much oil and coal for our energy, and everything that drives up demand, contributes to that.

        We had it 40 years and we will have it the next N-Thousand years because of the waste they produce. Also, Nuclear-Power was massive subvention by the gov. Actually a business-case that can not exist without subvention. So we all paid it with the taxes and we still pay because of the nuclear-wast. The idea to build new nuclear-plants, is a new subvention-scam by some lobbyists or tech-giants who want to pass on their costs to the general public.

There are many more millions of GPUs in computers and game consoles around the world burning electricity for your entertainment, for decades. The same class of devices. The environmental impact of having pretty pixels on your screens is at least an order of magnitude higher than what it is for AI, for inference and training. I don't see anyone being up in arms about that.

      I hear people advocating for the construction of nuclear reactors every day. They don't mention gaming, just like they don't mention refrigerators or washing machines specifically. A gaming machine consumes the same amount of energy as a machine used for AI, it's the same hardware. AI consumes it for seconds per user, while one gaming machine is used for hours per session. The energy required by one human to play a game for one hour could serve hundreds or thousands of AI users.

      That's his point? Greenpace wants AI datacenters to be built with clean energy. elpocko points out that plenty of other pointless electricity consumers also aren't being built with clean energy today. That's not an argument against green energy, but is pointing out that greenpace isn't very rigorous with their pleas. They're seemingly picking whatever is the most topical. We should be against this, because latching on to the latest thing basically guarantees that the next thing rolls around, all the momentum will be lost. Remember when everyone was up in arms about crypto mining? How it's barely brought up because everyone's focused on AI.

> Greenpeace calls for the following measures to minimize the environmental impacts of Artificial Intelligence:

> 1. An energy-efficient AI infrastructure powered 100% by renewable energy. This green power must be additionally generated.

    > If we care about saving a watt-hour, there are lots of places to look. Pointing fingers at the incredible energy consumption of internet-delivered HD video might not feel very comfortable to lots of folks.

    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.

    As long as energy production and consumption has severe downstream impacts, yes, we do need to wade into this territory.

    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.

    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 luxury) for air conditioning up, which is the Catch-22 in this case.

    The International Energy Agency (IEA) estimates that 10% of the globally generated energy is used for sir conditioning. But it would nevertheless be a good idea to require AI companies to care for renewable energy before they reach similar consumption levels.

    Regarding the "morass" … we tell people how fast they can drive, or companies to limit air pollution (at least in some countries) so no problem here.

    • Zacharias030 5 hours ago

      This is changing rapidly.

      Google announced they are serving 500T tokens per month. State of the art models are currently trained with less than 30T tokens. Even if training tokens are more costly to run (eg, a factor of 3x for forward, backward, and weight updates, and take another factor of 2x for missing quantization), you end up in a situation where inference compute dominates training after a very short time of amortization.

      • jillesvangurp 4 hours ago

        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.

    This really applies to any application which consumes high percentages of the resources available.

The rational of purpose and resource demand and expected effects is secondary to this. The primary question is about (significant) quantities.

      Do we as a society want to wade into the morass of telling people what kinds of activities they can use energy for?
    
    I mean, yeah, that's just basic civil regulation. Energy generation has massive negative externalities, and preventing waste is a worthy cause. I don't agree that AI must be singled out in that sense, but even it were, I imagine a modest push for efficiency would only help us in the long run.

      If we care about saving a watt-hour, there are lots of places to look. 
    
    Well put, but I think it's important to bring the analysis one level up, and look at emissions. In that paradigm, meat eating and non-essential travel (yes, including vacations to Rome, business meetings, scientific conferences, and other perceived-to-be-unalienable rights) are punching way above their weight class.

    For anyone who's curious on specifics re:AI emissions, the recent MIT article is the gold standard in terms of specificity, neutrality, and nuance: https://www.technologyreview.com/2025/05/20/1116327/ai-energ... .
