The ugly truth behind ChatGPT: AI is guzzling resources at planet-eating rates | Mariana Mazzucato
www.theguardian.com
Big tech is playing its part in reaching net zero targets, but its vast new datacentres are run at huge cost to the environment, says economics professor Mariana Mazzucato

Despite its name, the infrastructure used by the “cloud” accounts for more global greenhouse emissions than commercial flights. In 2018, for instance, the 5bn YouTube hits for the viral song Despacito used the same amount of energy it would take to heat 40,000 US homes annually.

Large language models such as ChatGPT are some of the most energy-guzzling technologies of all. Research suggests, for instance, that about 700,000 litres of water could have been used to cool the machines that trained ChatGPT-3 at Microsoft’s data facilities.

Additionally, as these companies aim to reduce their reliance on fossil fuels, they may opt to base their datacentres in regions with cheaper electricity, such as the southern US, potentially exacerbating water consumption issues in drier parts of the world.

Furthermore, while minerals such as lithium and cobalt are most commonly associated with batteries in the motor sector, they are also crucial for the batteries used in datacentres. The extraction process often involves significant water usage and can lead to pollution, undermining water security. The extraction of these minerals are also often linked to human rights violations and poor labour standards. Trying to achieve one climate goal of limiting our dependence on fossil fuels can compromise another goal, of ensuring everyone has a safe and accessible water supply.

Moreover, when significant energy resources are allocated to tech-related endeavours, it can lead to energy shortages for essential needs such as residential power supply. Recent data from the UK shows that the country’s outdated electricity network is holding back affordable housing projects.

In other words, policy needs to be designed not to pick sectors or technologies as “winners”, but to pick the willing by providing support that is conditional on companies moving in the right direction. Making disclosure of environmental practices and impacts a condition for government support could ensure greater transparency and accountability.

    There are layers of wrong and stupid to this article.

    Despite its name, the infrastructure used by the “cloud” accounts for more global greenhouse emissions than commercial flights.

    “The cloud” accounts for something like 80% of the internet across the entire planet. I’d be curious what 80% of transportation infrastructure would end being in comparison… no takers? We’re only comparing to (some) flights instead of, I dunno, the vast bulk of our fossil fuel powered transport infra?

    In 2018, for instance, the 5bn YouTube hits for the viral song Despacito used the same amount of energy it would take to heat 40,000 US homes annually.

    Oh no, the most popular song in the world used the same amount of energy as 40k homes in the US. The US probably has something in the range of a hundred million homes. The efficiency of computing equipment increases by a sizable percentage every single year, with the odds being good the same data could be served at 1/20th the cost today. So why aren’t we talking about, say, heat pumps for those homes? You know, since they’re still using the same amount of energy they did in 2018?

    …about 700,000 litres of water could have been used to cool the machines that trained ChatGPT-3… Additionally, as these companies aim to reduce their reliance on fossil fuels, they may opt to base their datacentres in regions with cheaper electricity, such as the southern US, potentially exacerbating water consumption issues…

    What is this idiocy? You realize that a chip fab uses something to the tune of ten million gallons of water per day, right? Ten million. Per day. I’m not even looking at other industrial processes, which are almost undoubtedly worse (and recycle their water less than fabs) - but if you’re going to whine about the environmental impact of tech, maybe have a look at the manufacturing side of it.

    Furthermore, while minerals such as lithium and cobalt are most commonly associated with batteries in the motor sector, they are also crucial for the batteries used in datacentres. The extraction process often involves significant water usage and can lead to pollution, undermining water security. The extraction of these minerals are also often linked to human rights violations and poor labour standards.

    Man, we’re really grasping at straws here. More complaining about water usage, pollution, water security, labor standards, human rights violations… wait, were we talking about the costs of data centers or capitalism in general? Because I’m pretty sure these issues are endemic, across every industry, every country, maybe even our entire economic system. Something like a data center, which uses expensive equipment, likely has a lower impact of every single one of these measures than… I dunno… clothes? food? energy production? transport? Honestly guys, I’m struggling to think of an industry that has lower impact, help me out (genuine farm to table restaurants, maybe).

    There are things to complain about in computing. Crypto is (at least for the time being) a ponzi scheme built on wasting energy, social media has negative developmental/social effects, etc. But the environmental impact of stuff like data centers… its just not a useful discussion, and it feels like a distraction from the real issues on this front.

    In fact I’d go further and say its actively damaging to publish attack pieces like these. The last few years I didn’t drive to the DMV to turn in my paperwork, I did it over the internet. I don’t drive to work because I’m fully remote since the pandemic, cutting my gas/car usage by easily 90%. I don’t drive to blockbuster to pick out videos the way I remember growing up. The sheer amount of physical stuff we used to do to transmit information has been and is gradually all being transitioned to the internet - and this is a good thing. The future doesn’t have to be all bad, folks.

      Thank you. The 700000 litres in particular pissed me off… that’s a 9 meter cube. Whoopdie doo

        For comparison, a single hydraulically fractured oil well uses over 100 times as much water.

      The reason the article compares to commercial flights is your everyday reader knows planes’ emissions are large. It’s a reference point so people can weight the ecological tradeoff.

      “I can emit this much by either (1) operating the global airline network, or (2) running cloud/LLMs.” It’s a good way to visualize the cost of cloud systems without just citing tons-of-CO2/yr.

      Downplaying that by insisting we look at the transportation industry as a whole doesn’t strike you as… a little silly? We know transport is expensive; It is moving tons of mass over hundreds of miles. The fact computer systems even get close is an indication of the sheer scale of energy being poured into them.

      and recycle their water less than fabs

      Which is actually a very good idea economics-wise but fabs didn’t care much for the longest time because while crucial it’s still a minor part of their operating infrastructure. They had bigger fish to fry.

      The thing is if you clean a wafer with ultrapure water, the resulting waste water might have some nasty stuff in it… but tap water has more stuff in it, just not as nasty. They generally need to process the waste water to be environmentally safe, anyway, doesn’t take much to feed it back into the cycle and turn it into ultrapure, again.

      Side note in case you’re wondering what it’s like to drink that kind of water: It’s basically a novel way to burn your tongue. The osmotic pressure due to lack of minerals will burst cell walls but you’re not a microorganism so you’ll most likely be fine and the load on your overall mineral stores is only marginally higher than when drinking ordinary water, we get the vast majority of our minerals from food.

      But the environmental impact of stuff like data centers… its just not a useful discussion,

      I’d say it is but more along the lines of feeding waste heat into district heating. Someone can shower with those CPU cycles.

      with the odds being good the same data could be served at 1/20th the cost today

      Gotta nitpick you there. According the Moore’s law (really more of a rule of thumb), the price of the silicon used to serve those videos should be 1/16 of what it is today. I’m not aware of any corresponding law that describes trends in energy consumption. It’s getting better for sure, but I’d be shocked if there was a 20x improvement in 6 years.
