I'm confused, do they really have such an impact? They are of course big and expensive, but surely most datacenters are relatively innocuous in terms pollution and general disruption to the area compared to any regular heavy-industry site, right? Please let me know if I'm wrong, I'm not sure.
EDIT: I do get it, it is mainly about local benefit not really about pollution or disruption, even if they are loud about that because it sounds better. Local municipalities should definitely charge significant land rents or zoning fees so that the community benefits. China has been very successful at this for decades.
EDIT: Very rough overview after some research, using Colossus 1 as reference, which is among the biggest GPU deployments. Not thoroughly verified, but it'll be around the right ballpark.
- Electricity: 150 MW live, with another 150 MW planned/studied. That is like adding a medium electric-arc steel mill or large chemical plant to the grid. A small standard power-plant can generate about that much.
- Land / space: About 217 acres and 785,000 sq ft. Footprint-wise, that is like a large factory campus or logistics park; much smaller than a mine, port, refinery, or industrial farm, but far beyond a normal commercial warehouse.
- Water: Roughly 1.3–3M gallons/day in public estimates. That is comparable to the consumptive water use of a small-to-mid steel plant or a large industrial cooling site; not refinery-scale, but locally significant.
- Air pollution: The servers are not the dirty part; the issue is on-site gas turbines/generators. That makes it more like a small gas peaker plant than a steel mill or chemical plant. Colossus 1 reportedly used up to 35 gas turbines before grid connection.
- Noise: Mainly cooling equipment, substations, batteries, turbines/generators. More like living near a substation or small power plant than near a mine, port, or metalworks.
- Traffic / logistics: Heavy during construction, then relatively light. Much less disruptive than a port, mine, farm, steel plant, or refinery, because there is no constant flow of ore, scrap, fuel, chemicals, crops, containers, or waste.
- Heat: Nearly all consumed electricity becomes heat. At 150–300 MW, the heat rejection is industrial-scale, closer to a small power station / large process plant than normal manufacturing.

- gruez 5mo ago>If anything, the current shift is about bringing datacentres in that same category. But datacenters are hardly that? Sure, maybe whatever musk's doing with on-site gas turbines might qualify, but it's hardly representative of datacenters, which are probably closer to light industry or warehouses in terms of local impact.
- vitally3643 5mo agoThe noise pollution is quite significant in the immediate area, and the heat output notably raises outdoor temperatures in a surprisingly wide area. That also of course ignores air and water pollution caused by the increased demand on electricity generation (or jet turbines spun up in the parking lot). But the point is they suck up land and resources for no material or economic benefit to the local population. There's absolutely no reason to build these things in or even near cities. They can be built in the middle of nowhere where they don't bother anyone with zero impact on the services they provide.
- oersted 5mo agoBut are they really at the same level of disruption as any steel, chemical, nuclear, gas, manufacturing, recycling... plant? A mine? A port? Industrial farming? I get it though, they don't mind if it benefits the local community, that's the issue. I suppose it does make a lot of sense for at least the local municipality to charge steep ongoing land rents or fees for the zoning license. And I suppose that requires national coordination, otherwise they'll just go the next town over, which is exactly what is happening right now. In China, local municipalities were very profitable for decades just from selling or renting land to industrial deployments. It had a big impact on the local tax burden and they were significant net contributors to the national budget, instead of the other way around.

- smw 5mo agoI think the idea that they raise outdoor temps over a wide area is a myth spread on facebook. The physics doesn't work out.
- swiftcoder 5mo agoJust adding a square kilometre of parking lots raises the surrounding temperatures measurably, so I don't see how building a datacenter that size is going to have less impact
- thefz 5mo agoNoise pollution is huge and water usage is through the roof which could worsen the effect of droughts where water is already scarce. Not to mention the imbalances they generate on power distribution.
