Big Tech's A.I. Data Centers Are Driving Up Electricity Bills for Everyone

Not just bills. These data centers, a major driver of new energy use, are contributing to climate change. Sadly it seems to be another way for large companies to offload externalities onto the public.
kolinko•5mo ago
Are they? IIRC MS & Google were running on carbon neutral sources.
rambojohnson•5mo ago
Carbon neutrality doesn’t refill a drained reservoir used to cool off these machines. Running your servers on wind power doesn’t make the millions of gallons they’re dumping into cooling systems any less gone.
arghwhat•5mo ago
The water cycle refills drained reservoirs - the "carbon cycle" is not one we want to be part of.

Also note that there's other cooling solutions than evaporative cooling, such as closed loop water cooling with chillers, cooling with sea water, using heat pumps to redirect the heat to district heating loops (making use of the heat!), just building in colder places requiring less cooling, etc.

cma•5mo ago
Google stopped claiming "operational carbon neutrality" shortly after the release of chatgpt.
aurareturn•5mo ago

  Are they? IIRC MS & Google were running on carbon neutral sources.
It's like saying "our crypto mining energy is carbon neutral" but ignoring the fact that if the carbon neutral energy is going into crypto mining, it's not going into something more useful. If crypto mining buys all the carbon neutral energy sources, then those sources aren't being used by other industries.

We have limited carbon neutral energy production.

croes•5mo ago
MS revised its climate goals thanks to AI

rambojohnson•5mo ago
To say nothing of the exorbitant amount of water used to cool these machines, we’re on track to face a water shortage crisis long before any other climate change impact.
arghwhat•5mo ago
Water availability is a regional climate change impact, which does not apply everywhere due to differences in water sourcing and weather patterns and how climate change affects these.

It's very stupid to evaporate potable water on purpose in dry regions, but note that many numbers in this area are highly sensationalized by taking e.g. the maximum design capacity of the cooling system instead of the actual load, and that there are several other cooling solutions. Most proper facts die tragic deaths before they make it to mainstream news media. :/

croes•5mo ago
Water vapor is a greenhouse gas
arghwhat•5mo ago
And sunlight causes skin cancer, but we don't want to boycott neither water vapor nor sunlight lest we will have no precipitation and no... life.

Water evaporates constantly in from soil, plants, and water bodies - most notably from the ocean itself, which is how ~babby~ precipitation is formed. Evaporation from a datacenter is unlikely to make any notable impact through water vapor. What it could impact is highly localized potable water availability and humidity in places with e.g. low precipitation and limited reservoir capacity.

And, again, note that other cooling methods are also in use, and that other things also use evaporative cooling.

Heck, even when evaporative cooling is used, it doesn't necessarily mean that the water escapes into the atmosphere! Both heat pipes and refrigeration cycles are forms of evaporative cooling where the gas is allowed to condense, cool and evaporate again.

croes•5mo ago
All the small things that affect the climate pile up.

> Water evaporates constantly in from soil, plants, and water bodies - most notably from the ocean itself, which is how ~babby~ precipitation is formed.

And CO2 is constantly released too. The point are the additional released greenhouse gases

BTW we kind of boycott sunlight, it’s called sunscreen

arghwhat•5mo ago
That's really doesn't apply to water vapor where the natural evaporation is many orders if magnitude grater than what were dealing with, and is a required part of the natural cycle to replenish water reservoirs, with the natural cycle being incredibly short and increased evaporation shortening that cycle.

The issue with greenhouse gasses is their potent impact combined with long lifetime. CO2 has to be slowly absorbed by e.g. plants, and adding more does not speed up the process unlike for water vapor.

You also cannot evaporate past 100% relative humidity, an amount of water saturation that naturally occurs. This is unlike gas emissions, where the sky is the limit.

> BTW we kind of boycott sunlight, it’s called sunscreen

Unless you're applying it to the sun, that's not boycotting sunlight, it's adapting to it. Not to mention that your skin requires sunlight, sunscreen just avoids overexposure.

grafmax•5mo ago
Many of the reports are not sensationalized, but based on the companies’ own reporting of water usage. Water is preferred for cooling the dense data centers needed for AI - other methods are inadequate. And 2/3rds of new data centers in the US are built in water-stressed areas.

While some reports may be sensationalized we deceive ourselves if we conclude that the water scarcity problem as a mirage. It’s a real problem.

But the vast majority of my $500+ a month PG&E bill is for transmission, not generation.
prasadjoglekar•5mo ago
And according TFA, those poles and wires for transmission are a large part of the increase in costs that are forecasted.

Ideally, the folks who request the new plants and transmission lines pay for them, but it appears tech cos are attempting to pass the transmission cost burden onto residential consumers.

teeray•5mo ago
Privatize the gains, publicize the losses
SR2Z•5mo ago
Poles and wires for a datacenter should be much cheaper than for a subdivision.
taeric•5mo ago
500 a month sounds steep. I'm assuming you live somewhere that requires AC every day?

The article referred to driving prices up from 2020 due to making the infrastructure stronger by as much as 30%. Which, yeah, about 150ish of your bill.

It is less clear on how much it will need to go up because of increased demand? The prediction is 8%. Which, again, not nothing. But it is telling that there is more increase from infrastructure than there is generation? I don't know that that will change?

hellisothers•5mo ago
My bill last month was $450 and I don’t own an AC, it was around $350 before I got a plug in hybrid but every year it goes up double digit percentages.
taeric•5mo ago
I'm curious what your major costs are, then? Without AC, pretty sure our costs were not even half that.

Granted, my memory is largely from when we lived in a smaller house.

SR2Z•5mo ago
PG&E charges about 50c per kWh. It's not very hard to have an electric bill that high when electricity costs ~5x the national average.
taeric•5mo ago
Ish? I'm still not clear where you would be using that much electricity.

I'm not claiming that you don't. Or that you shouldn't. I'm genuinely curious on where the main use of electricity is.

To add numbers, an AC can use up to 5000 watts. That is literally 10x a refrigerator. Over 100x what a TV uses. The car, I'd guess is using a lot. But where are you using that much energy without AC?

That is, even compared to your 5x energy costs, I should have been paying more to keep a decent sized house running with AC in GA since I almost certainly had more than that multiplier on my usage?

SR2Z•5mo ago
You get a $500 bill for using 1000 kWh/mo - that's just leaving a 5000W AC on for 200 hours. My apartment AC is probably 2000W, but similar principles apply.

Add in a fridge, cooking equipment, water heating, leaving a server on, etc., and it should be straightforward to get to that number.

taeric•5mo ago
None of this contends with my question? I get how an AC can lead to an expensive bill. I'm assuming your numbers are to intend running the AC for daytime hours and that it will get you there. How do you get there without an AC?

About the only other large power use thing I could think of would be a pool?

Searching also shows average power bills in CA are 160? If focused on LA, it would be 200ish? What is putting some folks here so far above average? Was that the quarterly bill? I know we get bills every few months.

SR2Z•5mo ago
I don't think you get there without an AC, but the point is that many people have AC and central air and use both of them.

My guess is that most people don't have AC or are sensitive to price increases and choose not to run it. There's also multiple electricity providers in the state; NorCal uses PG&E and SoCal uses Edison.

For a variety of complicated and corruption-related reasons, PG&E has jacked rates through the roof in an absolutely unconscionable way and Edison's rates have only increased by a lot.

taeric•5mo ago
So it sounds like we mostly agree? One of the starter posts was claiming 450 without AC. I'm curious how that happens. Even with AC, I was never seeing bills that big unless we were running it a lot.
hammock•5mo ago
You can thank all the wildfires for that
Avicebron•5mo ago
Yeah...I hate when wildfires neglect their infrastructure to the point that they start themselves
0_____0•5mo ago
That isn't unique to PG&E. Clear across the country, my utility bill is close to 60% transmission fees.

Also what are you doing? Running a flux capacitor?

nullc•5mo ago
PG&E peak residential rates hit over 50 cts/kwh.

PG&E works with a capture PUC and cost plus accounting where the only way for the company to increase profits is to drive up expenses.

buckle8017•5mo ago
this is nonsense and the author even admits it

> In the coming years, artificial intelligence could turbocharge those increases

the cost of residential power is going up because of the shift away from natural gas towards solar

failing to admit this or worse lying about it is not going to actually help long term

kolinko•5mo ago
what? solar is cheaper than natural gas.
mensetmanusman•5mo ago
Solar+battery is the proper comparison.
buckle8017•5mo ago
It's absolutely not.

Solar with batteries that provide power year long are so expensive they do not exist.

At most you get one day of battery.

specialist•5mo ago
You need to distinguish between generation and transmission.
southernplaces7•5mo ago
Oh hey, not even crypto pulled this kind of thing off, but here we now see crickets from certain parts of the tech community (on this site especially) about this particular gargantuan use of electricity. I guess it's no longer a problem when the people who employee you are doing it, despite the vast amount of slop, spam and other garbage being generated among the occassionally (only apparently so far) productive uses of LLM technology.

As far as that goes, i'd love to see a well researched breakdown of just what percentage of LLM technology is actually being used for anything productive, and what percentage is just being pissed into industrialized spam.

LLMs even have the whole crime angle neatly covered, considering all the innovative uses they're being put to by the same people who brought us ransoms paid in crypto. Would be interesting to see the numbers on how that breaks down too.

waltercool•5mo ago
It's usually the opposite.

When a company requires lot more energy, power plants are expected to produce lot more.

When a power plant produce a lot, the low consumption rates tend to get cheaper. It's gets cheaper to produce energy as the demand increases.

This is, of course, considering the input material is not scarce, like hydro power plants or wind power. Everything else (coal, oil, nuclear, gas, solar) should be easy to increase supply/demand.
