Out of curiosity, how are large data centers zoned?
micromacrofoot•11m ago
industry or heavy commercial, which is where some minor wrinkles have been coming up because they usually don't need special permission to build as long as the zoning fits

honestly I'm sure other industrial uses can cause temperature increases too, the nature of industrial zoning on its own tends to reduce green space which can lead to the heat island effect, so this is at least partially because hating on data centers is the issue du jour

pnw•10m ago
It's the issue du jour because of foreign influence. The situation in Phoenix is due more to poor zoning since the DC is right across the street from a residential area.

The Chinese and Russians didn't double my electricity rates this year.
pnw•5m ago
Neither did the data centers. Datacenters use less than 5% of US electricity.

https://arxiv.org/abs/2606.19777

estearum•6m ago
Or because people see:

1) their electricity bills rising

2) their land prices (read: rent) rising

3) actual fucking nutjobs in charge of these companies who can't seem to simply not say actual nutjob shit all the fucking time

4) entry level jobs disappearing

5) the obvious fact that "I am building the most powerful technology ever" means "the already-powerful people who own these technologies and companies are working to become vastly more powerful"

And I say this as someone who uses and loves using AI heavily across both my personal and professional life. It's better to grapple directly with the fact that people have very legitimate fears and concerns around this technology and the people who own it.

Zoning is a per-city and per-county thing. Traditionally, they usually occupied some sort of commercial / light industrial zones, the same as office parks and warehouses. But hyperscale stuff often requires one-off variances / rezoning.

"The attribution of this warming to data center waste heat is supported by the consistent alignment of the temperature signal with the prevailing wind direction across multiple sites, dates, and meteorological conditions. "

Well, no? That could also mean that the heat island effect of the (statutorily mandated) employee parking lot is causal.

duplessitous•10m ago
> The mean air temperature on the upwind side of the facility was approximately 42.7 °C, increasing to 43.5 °C in the neighborhood near the eastern boundary of the data center campus on the downwind side. The observed ΔT of approximately 0.8 °C extended roughly 500 m downwind

Seems like we do observe heating but a much smaller average delta T than the title would hint at; I didn't see a max distance they evaluated over, seems like 500-1000m was their search window from their text. The next paragraph discusses how one of the sites they compare to is a relatively lower average temperate than the rest of Phoenix. Not really convinced by this methodology. Seems like doing something in a flat field with an array of temperature sensors would be a much more robust way to look at heating effects over some reasonable distance. Plenty of data centers fit the bill of flat and semi-isolated, curious why they chose these sites to look at

so we can have totally useless "AI" customer service agents where you still have to demand to talk to a human to properly get a problem solved

The whole data center heat/water thing is like not even in the top 100 risks/issues related to AI, but it's all people seem to care about. Why is that?
5m ago
If you want people to be more supportive of it, there are pretty direct ways to do that. Donate heavily to the local community to make up for impact, build new power plants for the project to pay for itself, don't put in gas powered generators, stay away from housing...
nemomarx•6m ago
If they're zoned like heavy industry, that seems fine for any noise/ heat etc. If they're zoned for light industry or similar to office buildings like the other comment says I feel like that could have different impacts - an office building will have some of this but probably has much less equipment and energy needs, less venting heat out maybe?

But if we're going to keep factories and chemical plants away from housing we can keep data centers over with them I think. Out of sight, out of mind, less chance of local protestors, maybe even closer to good power plants for transmission. Everyone wins?

jeffbee•6m ago
> I'm sure other industrial uses can cause temperature increases too

If anything about this paper is accurate, which it clearly is not, then the >8000MW rejected to the atmosphere from the nearby Palo Verde power station should be raising the air temperature at least 250C, 1km downwind. Which it obviously does not.
