The vast data centers that power artificial intelligence are so energy hungry that they’re heating up their surroundings, according to new research. It’s an alarming finding given the number of data centers is predicted to explode over the next few years.

Years ago, I was driving through NY city-ish. We pulled over in a rest area and I saw a sign about turning your engine off. I thought it was the stupidest thing I had ever seen, as did many other people apparently as their cars were idling. Then I got out of my car. I was wrong. The heat was insane. I couldn’t wrap my little head around it. I started doing the engineer math thing because it didn’t make sense.

Doesn’t surprise me at all these massive data centers are creating little heat domes. The cars were bad enough, and they are a fraction of the energy.

100% of electricity burned turns to heat save light that leaves earth. Gigawatt data center? That's ~650,000 1500w space heaters.

i work for a large power company, we have a data center customer that have as many equally sized cooling towers as one of our nuclear power plants.

[–] tehn00bi@lemmy.world 24 points 3 weeks ago (8 children)

Pretty soon you’ll just have nuclear plants just to power data centers.

[–] ClockworkOtter@lemmy.world 20 points 3 weeks ago (1 children)

Didn't Microsoft try to pay for a nuclear plant to be recommissioned just to power a data centre or something?

[–] teyrnon@sh.itjust.works 14 points 3 weeks ago (1 children)

There have been several data centers that have bought nuclear plants, including Three Mile Island, they're going to fire that bitch back up, also the Regulators have been disempowered. Propublica on the last part if I recall.

Nuclear plants to power data centers to make ai slop to make more need for data centers to feed us ai ad slop...when does it fucking end?

I hope some vigilantes start taking action against these damn wastes of space.

[–] BanMe@lemmy.world 9 points 3 weeks ago

The disease is late stage capitalism, the symptom is a mad dash to trade our natural resources for energy and pollution. The mad dash will continue as long as we're bleeding humanity to keep the shareholders high and dry.

Isn't the largest data center currently something like 100MW? So "only" 0.1GW...65.000 space heaters is still insane though.

[–] mushroommunk@lemmy.today 10 points 3 weeks ago (1 children)

That currently exist? I believe Colossus is pushing 150MW and aiming for 300. But Gigawatt centers are on the way

we were asked 400MW for a new data center, we told them 100MW is the max we could provide for now, and increase later, we have a new natural gas plant soon to enter operation to replace two retiring coal plants, but looks like we're postponing decommission targets to keep demand

There's 33kWh worth of energy in a gallon of gasoline, and they use 0.3gal/hour when idling, so cars are pumping out 11kWh of heat just sitting there....that's a surprisingly large amount of heat.

[–] Eheran@lemmy.world 12 points 3 weeks ago (1 children)

33 kWh/gallon * 0.3 gallon/h = 10 kWh/h = 10 kW

But units aside, that is really nothing. The car itself already has about 3 m² area or about 3 kW of sunlight. The issue is the CO2 (globally) and pollution from the car (locally, causing smog etc.).

I'm not sure what you guys are worried about. All that extra heat will just dissipate into the atmosphere and eventually radiate into space. It's not like there's anything in the atmosphere that would interfere with this cycle... right?

[–] pennomi@lemmy.world 12 points 3 weeks ago

And we would’ve gotten away with it too, if it weren’t for you meddling fossil fuels, and cows too!

I sometimes work in the building that's in the thumbnail of the article, that's crazy to see.

But that being said, data centers are definitely a negative for the environment and using them for bogus AI nonsense is horrible.

The graphs in the paper show the temperature 1 km away from the data center being 8°C higher and attribute that to heat emitted by the data center. That should start the alarm bells that something isn't right with this paper.

Here's a post going into the problems with it;

[–] Bitflip@lemmy.ml 26 points 3 weeks ago

Its not enough. Donate fire to a nearby data center today to improve its temperature! 

[–] BagOfHeavyStones@piefed.social 22 points 3 weeks ago (4 children)

Would be nice if they built them in cold climates and piped the heat to houses and buildings like the steam era of old.

[–] kkj@lemmy.dbzer0.com 10 points 3 weeks ago (3 children)

Tax them enough to install geothermal heat pumps in the surrounding homes.

"Like the steam era of old"? 🤣

What you're describing is called district heating and is totally a thing in Europe. There actually are data centers in Europe that contribute to their local district heating grid.

Strikingly, the impacts weren’t limited to a data center’s immediate surroundings; temperature increases affected areas up to 6.2 miles away, the research found, affecting more than 340 million people.

Huh?

[–] Vorticity@lemmy.world 22 points 3 weeks ago (2 children)

Air and water move, especially when heated.

[–] Appoxo@lemmy.dbzer0.com 6 points 3 weeks ago (1 children)

But un a radius of 6 mi? That sounds a bit high.
More close to a city with lots of concrete to store the heat.

[–] AHemlocksLie@lemmy.zip 30 points 3 weeks ago* (last edited 3 weeks ago) (5 children)

Large data centers can consume over 100 MW of power. Almost ALL the energy a computer consumes is turned into heat, like well over 90%. A home AC unit pulls a little under 1 kW, and I think heating is about the same so that's equivalent to heating over 100,000 homes, except those homes will eventually get warm and stop running the heat. The data center churns all day, every day. Given that, it may be equivalent to all the heat put out in more like 250,000 homes. Data centers produce an ABSURD amount of heat.

Edit: and keep in mind, that's HOMES, not people. Average people per household in the US is 2.5, so that's heating for over 600,000 people.

[–] filcuk@lemmy.zip 8 points 3 weeks ago (8 children)

Sorry to nitpick but doesn't 100% of it end up as heat? Vibrations, light, sounds, radio waves- all a tiny fraction of the power are also eventually absorbed by the environment.
That was my understanding at least

Oh, 16 degrees Fahrenheit. Still, thats quite a bit.

[–] porcoesphino@mander.xyz 14 points 3 weeks ago (6 children)

Only a handful of countries use Fahrenheit, but they're still too arrogant to add the unit. I get not including Celsius because of the target audience, and dropping the unit in conversation but this isn't that

Seeing this kind of news hurts. I’ve had a lifelong interest in computers and technology. I’ve made a career of it and live fairly comfortably because of it. But this makes me certain the positives don’t outweigh the negatives. And I wish we could go back to the 90s/2k when we’re certain this tech would lead to the betterment of the world. Sort of bearing my heart here but technology sucks now.

As a lifelong datacenter tech it really sucks seeing what monster this has all become. And I don't know what else I would do to pay the bills.

[–] confusedpuppy@lemmy.dbzer0.com 11 points 3 weeks ago

I used to work in automation within the auto industry. Once I became aware of the damage I was doing by being an enabler, that shit began to eat away at my mental health. I knew I had to make an exit plan when all of my day dreams while working there involved Molotov cocktails.

I don't envy anyone who has to deal with that kind of mental load. Knowing the harm you're causing while wanting the opposite but still needing to survive the next day, week or month.

[–] tidderuuf@lemmy.world 9 points 3 weeks ago

This is perfectly timed because WA states legislature ended their session this year and decided not to take up the topic of regulating data centers. Even better knowing that the PNW just had the warmest winter in history, record low snowpack and nearly every month a new mega data center is opening.

[–] thingAmaBob@lemmy.world 7 points 3 weeks ago

Sometimes I wish the Epstein class would just mass bomb all us poors already and get it over with. This slow, painful death thing is extremely annoying and stressful.
