I think this is because the demand is so extreme for datacenters now that companies are building them in a manner that disrupts the environment around them. The newer ones are using on-site generators that are insanely loud and require multiples more power than datacenters have historically needed. For a rack with traditional servers with just RAM/CPU/Drives, 5kW is sufficient in most cases.
When you have racks that are full of 4U GPU systems that pull 3-6kW each, the power requirements per rack shoot up to 60kW+(with whole rack setups blowing past 100kW). So an AI datacenter requires over 20x the power compared to what they needed in the past. This either strains the power grid near the DC or they need to create on-site power to fulfill demand, which has noise and other concerns.
I work near a datacenter and you can't hear significant noise from the outside, maybe a slight humming sound but quieter than traffic. This is a DC that has been around for over a decade and uses power from the grid since most of the loads are non-GPU based.

I don't think the average person actually knows anything concrete about them.
They're a proxy for peoples' sense of powerlessness about what's going on around them.
Skyrocketing electricity prices, the sense that elected officials aren't looking out for their interests, job losses, etc. They're a convenient proxy for many disparate concerns because they represent all of those things in one way or another.

The average person around them knows quite a bit about the noise level, and how far it carries. They're starting to learn about the effect consistent noise at that level has on their mental & physical well-being as well.

I think there's truth to what you're saying but I also think there's truth to what people are experiencing and perceiving.
A highly power and/or water consumptive data center being installed in a town or city is pretty much a perfect embodiment of people's frustrations. It consumes tons of power and/or water and therefore drives up utility costs for the locals or pollutes the air with diesel exhaust. And it doesn't create jobs so it's just frankly some rich cabal of capitalists getting richer while people's lives continue to feel materially worse. I can't think of a better embodiment of the sort of confluence of crumminess that seems to be underway.

A new class of oligarchs are trying to obsolete every profession and human endeavor for the sole purpose of enriching themselves. You don't need a PhD in environmental policy or domain expertise in construction to listen to what AI advocates are saying and realize their success comes at the expense of society, and say "no thank you."
Data center construction is not a proxy for powerlessness, but the vanguard of the powerful.

In Nashville they messed up by trying to build one next to the zoo, a beloved and popular attraction (higher attendance than our NFL franchise). The public outcry was swift and effective, new zoning rules were passed last night. https://nashvillebanner.com/2026/07/21/nashville-data-center...

That's great for future sites, but how is that going to improve the zoo's situation?

From reading the article, it sounds like one of the three items passed was an extension of a moratorium on data center building specifically for the area around the zoo. Another item involves eminent domain for the city to buy the land next to the zoo for use as city office space instead. So it pretty directly impacts the zoo's situation.

Point to _any_ analysis that says the current building boom is anything but speculation.
xAI is renting out their DC space. I think I read that Google is, too.
DC buildout is purely a gold rush. A play to be the one left standing after all the weaker players die.

You’re probably thinking of Meta. Google renting GPUs is a less recent phenomenon, to say the least.

Speculation isn't a dirty word and both can be true.
Demand is very high today and exceeds capacity. Builders think demand will continue to grow. This seems plainly correct. Firms may differ in how high demand will go, but it is still more than today.

You are trying to pick a fight with a post that isn't making the point you assume it is. All that guy is saying is that there is a rush to build them, which is objectively true.
Whether or not the datacenters return on the investment is a different question.

There's a demand for data centers, but maybe not a demand for actual usages of the data centers. That's the distinction I think they were trying to make by pointing to existing data centers not even being used to full capacity in-house (and being rented out instead).

Site selection also isn't very thoughtful. A lot of pre-AI datacenters were placed a good distance away from places where people live, but time to operation seems to be the overwhelming priority now which is pushing them to build right in the middle of or next to developed areas.

They could build them somewhere where people don't care. But you can't co-opt 70 years of public infrastructure investments out in the middle of nowhere.

That's what they should do. Datacenters don't need to be in anyone's backyard. The US has vast amounts of unused land as well as urban brownfields that are sitting empty. Put them there.

You're not getting it into an urban brownfield unless it comes with price controls on energy.
I live amongst the urban brownfields of Baltimore and our politicians are under tons of pressure to stop data center projects (and to tar and feather utility executives).

Yes, the AI Datacenters are much worse for the environment. xAI is using methane-turbines to power theirs, and they are allowed to pollute your communities because they bribed the Trump admin.

I have some degree of sympathy for data centers, and anyone else that needs power, only because of how broken our regulatory state is on approving new transmission.
To be clear, it's not just data centers that have this problem. Journalists have been spilling digital ink on this topic as it relates to solar and wind farms as well. It's also part of the thing that'd hold back rapid deployment of nuclear.
If there's a strong enough economic incentive then yeah people are going to try to optimize around broken government.

Lol. A data center is no more than a industrial bread bakery (oddly specific i know). The entire anti-data US center is ran by China. EG. You can run a rack of servers in your closet. China is doing a great job.

There are industrial bakeries that burn that much natural gas (powerwise); although the bakery probably smells better.

I can attest for the smells better. Now, I'm left wondering which smells worse, an AI datacenter or a large beer brewery. As a kid, we had a Mrs. Baird's bread bakery which was in the heart of town that students would take field trips to see (which is no longer there and is now apartments). On the other side of town is a Budweiser plant, and it's infamous for being so odorific but it is located way the hell out there.

I suspect the Nabisco plant in Chicago pulls about ~12 million therms worth of natural gas, at 30kwh per therm, that's pretty significant.

You asked about energy usage; but I have no idea as to how that bakery's natural gas usage affects the people surrounding it.
The smell of freshly baked fig newtons might offset the possible increased cost of gas-per-cubic-foot.
