Bitcoin Miners Saw the AI Power Crunch and Nuclear Revival

Nuclear energy Bitcoin mining has gone from niche experiment to industry blueprint — and the surprising part is that crypto miners figured this out years before Microsoft, Amazon, or Meta did. Now, as AI-driven data center demand pushes utilities toward a full-blown nuclear renaissance, the playbook those miners wrote is being photocopied at scale.

Big Tech Is Late — Miners Were Already There

Call it prescience, call it necessity. Either way, Bitcoin miners were colocating next to nuclear plants while AI hyperscalers were still writing sustainability reports. According to TheEnergyMag's Miner Weekly newsletter, recent utility filings suggest the US may be entering a full nuclear renaissance — driven by long-term power contracts with AI data center power demand giants like Microsoft, Amazon, and Meta. Rather than relying on renewable energy credits, these companies are now backing entire nuclear facilities to lock in 24/7 carbon-free power.

What the newsletter doesn't belabor — but deserves emphasis — is that miners got here first. Not by months. By years.

What Percentage of Bitcoin Mining Uses Nuclear Energy?

The numbers have been climbing steadily since 2021

Nuclear energy's share of Bitcoin mining electricity was already growing before anyone in Silicon Valley was paying attention. Researchers at the Cambridge Centre for Alternative Finance tracked nuclear energy Bitcoin mining trends and found that nuclear accounted for roughly 4% of mining power in 2021, climbing to nearly 9% in 2022, and has since edged toward 10%. Taken across all sustainable sources — nuclear, hydropower, wind — the share of Bitcoin mining's electricity now sits at approximately 52.4%.

That's not an accident. It's the result of miners making hard infrastructure bets when those bets were deeply unfashionable.

Miners recognized early that nuclear power — once viewed as a declining industry — could become critical infrastructure for the next generation of high-performance computing.

TeraWulf and the Nautilus Cryptomine

The clearest early case study is TeraWulf, which in 2021 formed a joint venture with Pennsylvania-based Talen Energy to build the Nautilus Cryptomine facility — positioned to draw electricity directly from the Susquehanna nuclear power plant. No energy credits, no offsets. Direct nuclear power to mining rigs.

That structure is almost identical to what hyperscalers are now pursuing. The difference is that TeraWulf did it when nuclear was still considered a stranded asset, not a strategic one.

What Does SMR Adoption Mean for Miners?

Small modular reactors are the next chapter — and this one miners and Big Tech appear to be entering at roughly the same time. SMRs are designed for faster deployment and easier colocation with energy-intensive infrastructure, making them a natural fit for both data centers and large-scale mining operations. Google has already signed SMR development agreements to power future computing facilities, according to reports, suggesting the model could spread quickly across the high-performance computing space.

For Bitcoin miners, SMR adoption would extend a pattern they've already established: get close to dense, reliable power before anyone else realizes it's scarce.
