    I'm dismayed by the current political discourse on this topic. Seems like the two camps are 1) let mega corps build data centers with impunity or 2) use NIMBY tactics to oppose them in all cases.

    I want to see a pro-growth approach that makes the mega corps assume the costs of their negative externalities. I want to see an increased build out of renewable and nuclear energy sources. I want to see environmental protections in place to limit impacts on aquifers and other water sources.

    Democracies don't handle nuance well.

      There’s the pro-growth Abundance faction, but they’re captured by special interests, so they’re predictably advocating for supply-side YIMBYism and relaxed regulation, without addressing the political economy that led us to the current situation.

      Especially when modern discourse revolves around 140-character hot takes.

    > For longer queries or requests that rely on AI agents or reasoning, the footprint is higher. Epoch AI estimated that a long query (7,500 words of input) could consume about 2.5 Wh, and a very long one (75,000 words) could consume 40 Wh. Those are far higher than the simple text query.

    One thing that's missing from almost all of these energy estimates is the impact of "agentic" queries, which were rare a year ago and increasingly common today.

    I've asked questions of GPT-5.6 Pro that take 19 minutes to return an answer, as the model runs hundreds of search and site navigation tool calls (and a bit of executed Python code too) trying to get to a credible answer.

    I'm confident that 19 minutes involves a lot more than 75,000 words worth of tokens.

    With coding agents we can at least get an accurate token count. I'm already at 204,000 tokens of GPT-5.6 Sol today and I haven't started work yet.

      Where did the tokens go?

    Select quote:

    * 5% of electricity in the United States is used to power data centers. For AI-focused ones specifically, it’s probably around 2%.*

    I think it’s massive.

      >I think it’s massive.

      So what about the other 3%? That's not "massive"? Or it gets a pass because it's not AI? The whole debate over datacenter resource consumption feels like a rorschach test. Either you think the technology is transformative and therefore the resource consumption is justified, or you think it's slop and therefore any resource consumption can't be justified.

        If it was 2% for VOD streaming, and 3% for every other service that is delivered by a networked computer, I would think "wow, streaming is huge". 2% for one thing that most people hardly use at all, versus 3% for everything else on the computer, is still a remarkable statistic. I'm not making any value judgment in order to say that.

        I also don't think it's particularly conclusive about anything though. It doesn't on its face make me think anything like "it must be stopped", but it's remarkable.

          AI is hardly used at all? Basically every company and consumer in the country is using it, transitively if not directly.

        How did you read that in my comment?

    The author claims it's surprising that AI uses less electricity than the rest of data centers. Why?? Data centers do a million different things other than AI
    • Aurornis 36 minutes ago
      It's surprising because that's all anyone hears about right now.

      Many are surprised to learn that data centers use much less water than golf courses or pools. We hear about it so much in the news it sounds like it's the overwhelming largest consumption problem around.

      • axus 29 minutes ago
        If they use so little water and power, why aren't they being built in the empty office buildings? Seems like commercial real estate was made for ... commercial activity.
        • fxwin 19 minutes ago
          Nobody is saying that they use "so little water and power", just that the average person has no clue about the orders of magnitude at which anything outside of a private household uses these things, including things they previously didn't really have a problem with (like golf courses or almond farms)

          Most people just hear <gigantic number of m³ or kWh> and their brain goes "damn, that must be a lot, i don't use nearly that much at home"

        • rick_dalton 24 minutes ago
          This makes no sense? How is one even correlated with the other? Data centers obviously have much different requirements than office buildings for people. On a very small scale this works but not on a larger scale.

        I wonder if we made tech billionaires choose between keeping their golf courses or building more AI data centres what they would go for.
    • StrauXX 42 minutes ago
      AI hardware is much, much more powerhungry than traditional processors though. I can understand their reasoning.
      • lopis 38 minutes ago
        Sure, but it's still surprising that 1/3 of all data centers in the whole world are dedicated to that one use.

    We all just look at energy as a price. I think more people are concerned if our prices will go up, not how much energy it uses. The bigger question is water.

    How much water do they use? Is it potable to begin with? Is it usable after? Will they drive prices up. These are one time builds with minimal jobs created after for a tech that could end my career. If I lose my job, I don’t also want to have no water and higher bills.

    I think its easy to forget how much energy is required to boil a liter of water, and these charts are a great reminder of the mundane things like that which escape our attention.
  • lordnacho 23 minutes ago
    I presume running an electric shower includes heating up the water? Otherwise I don't understand how it could be so energy intensive. The energy is the mgh of the water lifted, plus the heat you put into it. Heat tends to be by far bigger in that calculation unless I've missed something.
    • shipman05 20 minutes ago
      Yes. They're likely referring to on-demand electric heating units that are installed near the shower head.

      Our World in Data is based in the UK. Electric showers like this one https://www.mirashowers.co.uk/p/showers/shop-electric-shower... are more common there than they are in the US.

        Ok, I'll admit I was astonished half of showers are electric in the UK as I've not seen one since I was a kid.

    Our World in Data is great, but this article would've been improved if it offered a chart that offered a comparison to it's leading "1.5% of global electricity number".

    For example: 7% to 10% of all global electricity is consumed by air conditioning. It's not hard to think of relatively small interventions that could save 1.5% of global energy use annually.
