This is an economics problem: if the cost of energy is lower or equal to the benefit of consuming it, the energy will be consumed. As more and more energy is consumed to run these datacenters, price of energy will go up, and datacenters will learn to either be more efficient, or will pass on these costs to their users who will learn to be more efficient. Of course, there might be inefficiencies like subsidies and monopolies that distort the market for energy for a while, but in the long run, this is a self-fixing problem.

The issue is an environmental one. The cost here is environmental damage. The solution will need to be policy decisions that take that damage into account.

  That's why much of the world is gradually shifting over to renewable energy usage. In a world where energy is renewable, does not generate greenhouse gas and (hopefully) does not produce other externalities, our best way of dealing with these resource allocation problems is the free market. The alternative is regulation, which, I'm not even sure how it could be used to address this particular issue. Ban AI or crypto? Humans will find new ways to waste vast amounts of energy with computers. Require that computers have a certain efficiency rating of megaflops/joules? People will use more of this now far more efficient computing, resulting in more overall usage. Require corporations to be audited for energy efficiency and be certified? Goodbye all small players that cannot handle all the overhead of such legislation.

        State of the art compute capabilities, aka hardware, is already built in other nations. Mandating domestically owned servers is commonplace. And this was in response to someone whose best idea was “ban ai”

      Is the problem the data center or is the problem carbon emissions? How about tax the carbon emissions.
  - keyringlight 2y ago
    The trouble I see is that new consumption matching (or even some locations where proposed DCs exceed) new green generation may not let us displace dirty generation such as coal, which we should be looking to eliminate. The other issue that comes up with green generation is how variable it is, sometimes it'll be cloudy and still air, others will be windy and sunny, and the grid needs to capable of supplying everyone in both scenarios and not overbuilding generation they can't turn off. Having industries available to soak up an appropriate amount of energy available within their ecosystem would be great, but it's a hard sell to anyone to invest billions in sites where there could be no guarantees on utilization if they get bad weather for a few months. If there is any "plays nicely with others" regulation on consumption of a common resource, it's going to be reactive to problems than ahead of time.

      The solution to all of these problems is an aggressive buildout of nuclear fission plants to provide baseline power and accelerate the closure of all remaining plants which burn fossil fuel. Subsidized if necessary, as essential infrastructure.
      - TheDudeMan 2y ago
        Which is better -- subsidize what you perceive to be the solution or tax what is known to be the problem (carbon emissions)?
        samatman 2y ago
        Infrastructure is routinely subsidized because of the benefits it brings. Taxing the problem can help pay for that subsidy, that has some hazards because now government revenue depends on carbon emissions, but it can be part of the solution, sure. Tax revenue all goes in the same bucket no matter what the government claims. It helps that the actual electrical generators don't care where the steam is coming from, so we could be leveraging the gensets from decommissioned coal plants in fission reactors. All that's missing is the political will.

  It would be great if more externalities were priced in to the cost of energy, but there doesn't seem to be anything special about AI datacenters vs. any other use of energy. Data centers actually seem much more consciences about the impacts of their energy. I don't think I've read any headlines about cement plants trying to switch to 100% renewable.

Everyone else has to pay the price that data centers are willing to as well. And they can afford quite high prices before having margin troubles - likely much higher than what we as residents want to pay for energy.
- teitoklien 2y ago
  This is on the assumption that supply will continue to remain constrained, excess energy usage, might as well be the investments necessary to shift to more Solar Panels and renewable energy storage, high compute intensive workloads can be executed anywhere, higher energy usage, might as well incentivise optimising AI, Research and Other Compute-intensive training workloads to shift to day time, when solar power peaks, and process everything during that time. The capabilities that this unlocks are tons, driving more investment into advanced battery tech, solar tech, etc. Higher Consumption also drives investments to generate Higher Supply and hence future surplus and improvements in standard of living.
  - jononor 2y ago
    Yes, you are right in that. However we are not yet seeing much uptake in very flexible compute that works only during high energy production. And while I would love to see it, I am not sure we will anytime soon. One reason is capital costs of the compute equipment - if one only runs 25% of the time (daily solar peaks) - then it takes 4x as long to pay back the equipment. And we are still improving energy efficiency of compute a lot over time, so upgrading the equipment often is very beneficial in terms of TCO. Longer payback times is in conflict with that.

Are environmental externalities accounted for? How do we accurately measure the 'benefit' of something when it's still largely speculative (ie. AI is not providing as much value RIGHT NOW, but we think it will in the future). Economic problems are rarely just economic problems, and saying that it will resolve itself in the long term is dismissive and offers no value to the discussion.

  The environmental externality of new energy in the US is likely ~0, potentially even net positive, because approximately all new energy in the US is renewable, and displacement effects are likely to dominate the small-single-digit percentage of nonrenewables and the marginal environmental cost of the renewables themselves.

      This is a straw man usually used by anti electric car people. There’s always an impact. If you had a sandwich for lunch, the wheat in the bread destroyed a grassland somewhere. Usually in context of energy, we’re talking about carbon impact.

  Bitcoin network produces exactly the same number of bitcoins over time regardless of how much power it consumes; AI, even if you are unimpressed by the quality, does actually make more stuff when more energy is consumed.

Yes, however the economic situation develops not necessarily to most people's advantage. A (hypothetical) AI that can perform any intellectual labour at for an energy cost of 1 kWh to produce output at the quality and quantity levels of a median human working for an hour, at $0.1/kWh is going to be a better economic choice than 50% of humans on earth even if those humans cut their wage demands to the UN abject poverty threshold. But at the same time, there's not (currently) enough electricity for 50% of the world's people to be replaced by such AI regardless of the price. Thus energy prices rise until the machine labour is as expensive as the human labour. But that likely results in a lot of people even above that threshold no longer being able to afford to keep the lights on. If we only get this AI quality/cost/generality level around 2031-ish, that may be fine, because renewables are on an exponential growth curve and around then exceed current global demand all by themselves.
