Keep in mind when Elon Musk made Bitcoin crash by tweeting that Tesla would cease accepting it because of environmental considerations, and everybody was fearful concerning the environmental affect of proof-of-work mining? That was in 2021, and degens haven’t forgotten.
But right this moment, Musk’s xAI is constructing what is perhaps the world’s largest AI supercluster, with governments dashing to create legal guidelines to spice up AI innovation—whereas hardly anybody is questioning the vitality consumption.
A brand new peer-reviewed analysis paper printed within the scientific journal Joule revealed that synthetic intelligence may account for as much as 49% of worldwide information middle electrical energy utilization by the top of 2025—surpassing even Bitcoin’s infamous vitality urge for food.
Alex de Vries-Gao, a PhD candidate at Vrije Universiteit Amsterdam and longtime Bitcoin vitality consumption critic, discovered AI’s energy demand may hit 23 gigawatts by January 1, equal to about 201 terawatt-hours yearly. Bitcoin at the moment consumes round 176 TWh per 12 months.

“Massive tech firms are effectively conscious of this development, as firms equivalent to Google even point out having confronted a ‘energy capability disaster’ of their efforts to broaden information middle capability,” de Vries-Gao wrote on LinkedIn. “On the identical time, these firms favor to not speak concerning the numbers concerned.”
“Since ChatGPT kicked off the AI hype, we’ve by no means seen something like this once more,” he added. “Because of this, it stays nearly unattainable to realize a great perception into the precise vitality consumption of AI.”
In contrast to Bitcoin’s clear vitality consumption, which anybody can calculate from the community hash fee, AI’s energy starvation is intentionally opaque. Corporations equivalent to Microsoft and Google reported rising electrical energy consumption and carbon emissions of their 2024 environmental experiences, citing AI as the principle driver of this development. Nevertheless, these firms solely present metrics for his or her information facilities in whole, with out particularly breaking out AI consumption.
For the reason that tech giants refused to reveal AI-specific vitality information, de Vries-Gao adopted the chips. He tracked Taiwan Semiconductor Manufacturing Firm’s chip packaging capability, since nearly each superior AI chip requires its expertise.
The maths, de Vries-Gao defined, works like a enterprise card analogy. If you know the way many playing cards match on a sheet and what number of sheets the printer can deal with, then you’ll be able to calculate whole manufacturing. De Vries-Gao utilized this logic to semiconductors, analyzing earnings calls the place TSMC executives admitted to “very tight capability” and being unable to “fulfill 100% of what clients wanted.”
His findings: Nvidia alone used an estimated 44% and 48% of TSMC’s CoWoS capability in 2023 and 2024, respectively. With AMD taking one other slice, these two firms may produce sufficient AI chips to devour 3.8 GW of energy earlier than even contemplating different producers.

De Vries-Gao’s projection confirmed AI hitting 23 GW by finish of 2025, assuming no extra manufacturing development. TSMC has already confirmed plans to double its CoWoS capability once more in 2025.
Energy demand is unlikely to decelerate. Nvidia and AMD introduced file income, whereas OpenAI introduced Stargate, a $500 billion information middle enterprise. Certainly, AI is essentially the most worthwhile enterprise within the tech business, with any of the highest three tech firms on this planet surpassing the overall market capitalization of all the $3.4 trillion crypto ecosystem.
So the setting will in all probability have to attend.
