For a few decades now we have had increases in efficiency that have been able to reduce electric demands. Better motors, better lights, better appliances, better air conditioners, better TVs. This has been an application of Amory Lovin’s ‘soft energy path’. Crypto mining has been irresponsible and data centers are irresponsible, both as massive demands. But just think of the demands if the computer hardware were all 1990’s vintage power sucking CPUs.
Ooo.....this may be more of a stretch than you think.I think a lot of times people have blind spots (and we're all guilty of it)
Where there's a sort of NIMBY'ism aspect at play (just not the typical kind we're used to talking about)
People obviously don't love the utility price hikes, some don't love the environmental impacts, but they love the outgrowths of what the data centers accomplish -- just as long as it's not near where they live, and doesn't impact them personally.
What's strange is that, before AI, it seemed our reasonably sized data centres were not that problematic. But the way you characterize individuals spending time online makes it sound like they are the reason we suddenly need these huge, problematic data centre and they shouldn't complain. Indicating they're hypocrites doesn't feel like a very honest appraisal of the affects of AI and these data centres on communities that were not considered problematic before. It seems like you're just trying to silence criticism of these centres by the people who would feel the direct impacts.If a person uses search engines, does online shopping, likes the ability to work remotely, or just mindlessly doom scrolls their social media feeds for hours per day...guess what, they're reaping the benefits of datacenters (at least 1 or 2 of those things applies to most people in the US). Seems a tad hypocritical for people to make a big fuss about it.
In essence, it's "I want just enough of them in other peoples' neighborhoods far far away from me to be able to provide the things I like, but don't you dare build one in my neighborhood for purposes that don't approve of!"
It's not just LED light bulbs. It's furnace fans, air conditioning compressors, industrial electric motors, more efficient computers, and a variety of things that can be improved upon. There is still a considerable base of inefficient items out there that can be replaced either at EOL or before.Dropping energy use per consumer due to increased energy efficiency of appliances. Note: unless a load is mostly lighting, shifting to LEDs doesn’t have as much impact as some think.
Sort of. Once we have captured ALL of the possible efficiencies then the increased number of consumers will obviously increase electrical demand. Of course electric cars will also increase demand. The almost humorous part of that is that California pushed EVs very hard and then in shortages they had to beg people not to charge up their cars.Anyway, dropping energy use per consumer is offset by increased numbers of consumers, whether data centers or crypto mining is built or not.
IF they had a 50% generation rule there would be a coal train a day pulling up to their facility. And coal dust blowing off the coal heap. And even MORE water used, depleting local wells.

Almost none of whom are going to be locals.One thing about these data centers - sure, it takes a bunch of people to build one.
Not sure how you conclude that. Those in those rural areas don't need those from blue cities telling them that annoying hum, raising energy rates, and decreasing property values, what they are literally experiencing, is something they should reject.Please reread my post: It’s blue cities telling red rural areas that we don’t want data centers. Let that be our decision, not their’s.

I assumed we would be talking about the new data centres being built and not historical ones (Which partially explains the NIMBY phenom).I can't speak for the data center landscape in Canada where you're located, but as far as the US goes --
Only about 30% of data center capacity in the US is devoted to AI, and very few datacenters were/are purpose-built AI facilities. The overwhelming majority of the AI ramp up involves datacenters that already existed, running AI workloads in addition to the normal cloud services like storage, email, e-commerce, and search engines.
BloombergNEF puts total US data center power demand at almost 35 gigawatts, and estimated AI's share at about 6-9 GW.
MIT Technology review (which I hope would know their stuff in this regard) published the following:
Data centers in the US used somewhere around 200 terawatt-hours of electricity in 2025, roughly what it takes to power Thailand for a year. AI-specific servers in these data centers are estimated to have used between 53 and 76 terawatt-hours of electricity.
So the two estimates (despite measuring different metrics) appear to line up, which is: AI-specific stuff is responsible for about 20-30% of the power consumption. The other 70% is the "traditional data center stuff"
So I think, at least with regards to the US landscape, my statement still holds up.
Traditional Data Centers vs. AI-Ready Data Centers: A New Era of InfrastructureThese next-generation facilities are custom-built to support the heavy and complex needs of AI workloads.
Unlike their traditional counterparts, these facilities are purpose-built to handle high-performance computing (HPC), ultra-fast networking, and advanced cooling systems.
Clearly the new centres are not really comparable to the old ones. You are welcome to continue to trot out impressive "systems related" numbers but it doesn't really matter if the localized impact does NOT really reflect older trends.
And what communities getting these centres are expecting are SIGNIFICANT drains on resources.
Can you accept that this is a reasonable concern?
In my province the town of Olds Alberta is getting a data centre...9000 people. You think their electricity and water usage is NOT going to be impacted by a data centre? Pffffffft.
In the past couple years, perhaps, but there are approximately 3000 data centers planned or currently under construction (more or less doubling the current number - which also appears to have more or less doubled in 2025), and most of those will be dedicated to AI tasks - which are far more power-intensive (10-20x as much) on a per-rack basis.I can't speak for the data center landscape in Canada where you're located, but as far as the US goes --

I'm not seeing that article, but they also say this:BloombergNEF puts total US data center power demand at almost 35 gigawatts, and estimated AI's share at about 6-9 GW.
Data center electricity demand has grown more than 400% in the past 10 years and 150% in the last five years. Development shows no signs of slowing. Through the first quarter of 2025, a cumulative 23 gigawatts (GW) of data center IT capacity was live in the United States with 48 GW under construction or committed to be built.

Data-center power demand hits 106 gigawatts (GW) by 2035 in BloombergNEF’s newest forecast – a 36% jump from the previous outlook, published just seven months ago.
The massive growth rate in data center power demand reflects more than a surge in the number of data centers in the pipeline; it also highlights the new centers’ size. Of the nearly 150 new data center projects BNEF added to its tracker in the last year, nearly a quarter exceed 500 megawatts. That’s more than double last year’s share.

Interesting - I don't know if you changed the year, or if you're referencing an AI result that did [it would help if you provided links to your sources], but the original article that this stat is from says those were the numbers in 2024:MIT Technology review (which I hope would know their stuff in this regard) published the following:

(scroll down to part 4) We did the math on AI’s energy footprint. Here’s the story you haven’t heard.Data centers in the US used somewhere around 200 terawatt-hours of electricity in 2024, roughly what it takes to power Thailand for a year. AI-specific servers in these data centers are estimated to have used between 53 and 76 terawatt-hours of electricity.
By 2028, the researchers estimate, the power going to AI-specific purposes will rise to between 165 and 326 terawatt-hours per year. That’s more than all electricity currently used by US data centers for all purposes.
I don't think it does. I don't know if you're deliberately cherry-picking data to support your opinions, or if you've been mislead by sources that seem to agree with you, but it's clear that the energy demands from AI are rising precipitously, and are predicted to continue doing so for at least the next decade, barring some revolution in energy efficiency or a total crash of the bubble.So I think, at least with regards to the US landscape, my statement still holds up.

That same article, two paragraphs later, has this to say:

I think it's wholly reasonable for US energy consumers to be wary of that, especially because many data centers are getting significantly discounted rates on their electricity - meaning that existing customers will have to shoulder a substantial portion of the bill for the increased generation capacity and infrastructure improvements required to supply them.
No, because the complaints I'm seeing aren't really about immediate, neighborhood-level impacts.Wouldn't all of this still tie in with my original statement?... that people who were okay with it for things they like when it was impacting other peoples' neighborhoods for the last 10 years are hypocritical in that they only seem to be concerned when it's going to impact their neighborhood?
You tell me it didn't happen and then you tell me it did. OK. I haven't lived in a locale where that happened (or didn't happen, or whatever).Sorry, please show me where California "beg people not to charge up their cars." It didn't happen, despite Republicans and Right Wing media falsely claiming that is what was said.
What actually happened, in the midst of record high temperatures in California, is California asked people not to charge their EV between 5 and 10 PM, when power demand was expected to be at its highest, and instead charge before that time period. It is also worth noting that the majority of Californians charge their cars overnight (I believe starting after 10 or 11 pm) as that is when demand drops and there are lower energy rates.
Well okay but the...the other point is that the other data centres were smaller and didn't have the same kind of impact on their community as these new ones would.It's a reasonable concern, but it's only a concern people seem to have once it starts to impact them personally, which was kind of my point lol.
But those data centres, on the whole, were MUCH smaller and so their impacts, though already a strain, is simply going to be amplified in new communities. IOW, AI data centre's impact, though previously great, is getting greaterThe fact is, the same concerns they have about their own communities, are the same concerns numerous other people in other communities have been dealing with for the last 10 years.
Yeah. I wouldn't say that's the greatest comparison...for a few reasons.I would perhaps call it the "needle exchange effect"
"Needle exchanges are great, and when you look at it logically, makes more sense than our prior approaches"
...a few months later...
"oh wait, you want to put one of those places next to MY house?!?!"
What we don’t need are a bunch of self-proclaimed elites who consider us fly-over country telling what to do.Not sure how you conclude that. Those in those rural areas don't need those from blue cities telling them that annoying hum, raising energy rates, and decreasing property values, what they are literally experiencing, is something they should reject.
Uh-uh: We’re seeing that right now. I know, because every year I have to run the numbers for work. That’s why energy demand increases despite individual use decreasing. The population increase offsets energy use decrease.Sort of. Once we have captured ALL of the possible efficiencies then the increased number of consumers will obviously increase electrical demand.
