AI Is Eating Data Center Power Demand—and It’s Only Getting Worse

AI’s power use already represents arsenic overmuch arsenic 20 percent of world data-center powerfulness demand, research published Thursday successful nan diary Joule shows. That request from AI, nan investigation states, could double by nan extremity of this year, comprising astir half of each full data-center electricity depletion worldwide, excluding nan energy utilized for bitcoin mining.

The caller investigation is published successful a commentary by Alex de Vries-Gao, nan laminitis of Digiconomist, a investigation institution that evaluates nan biology effect of technology. De Vries-Gao started Digiconomist successful nan precocious 2010s to research nan effect of bitcoin mining, different highly energy-intensive activity, would person connected nan environment. Looking astatine AI, he says, has grown much urgent complete nan past fewer years because of nan wide take of ChatGPT and different ample connection models that usage monolithic amounts of energy. According to his research, worldwide AI power request is now group to surpass request from bitcoin mining by nan extremity of this year.

“The money that bitcoin miners had to get to wherever they are coming is peanuts compared to nan money that Google and Microsoft and each these large tech companies are pouring successful [to AI],” he says. “This is conscionable escalating a batch faster, and it’s a overmuch bigger threat.”

The improvement of AI is already having an effect connected Big Tech’s ambiance goals. Tech giants person acknowledged successful caller sustainability reports that AI is mostly responsible for driving up their power use. Google’s greenhouse state emissions, for instance, person accrued 48 percent since 2019, complicating nan company’s goals of reaching nett zero by 2030.

“As we further merge AI into our products, reducing emissions whitethorn beryllium challenging owed to expanding power demands from nan greater strength of AI compute,” Google’s 2024 sustainability study reads.

Last month, nan International Energy Agency released a report uncovering that information centers made up 1.5 percent of world power usage successful 2024—around 415 terrawatt-hours, a small little than nan yearly power request of Saudi Arabia. This number is only group to get bigger: Data centers’ energy depletion has grown 4 times faster than wide depletion successful caller years, while nan magnitude of finance successful information centers has astir doubled since 2022, driven mostly by monolithic description s to relationship for caller AI capacity. Overall, nan IEA predicted that information halfway energy depletion will turn to much than 900 TWh by nan extremity of nan decade.

But there’s still a batch of unknowns astir nan stock that AI, specifically, takes up successful that existent configuration of energy usage by information centers. Data centers powerfulness a assortment of services—like hosting unreality services and providing online infrastructure—that aren’t needfully linked to nan energy-intensive activities of AI. Tech companies, meanwhile, mostly support nan power expenditure of their package and hardware private.

Some attempts to quantify AI’s power depletion person started from nan personification side: calculating nan magnitude of energy that goes into a azygous ChatGPT search, for instance. De Vries-Gao decided to look, instead, astatine nan proviso chain, starting from nan accumulation broadside to get a much world picture.
