As artificial intelligence accelerates digital workloads, the race is on to deliver higher-density performance without sacrificing energy responsibility. Sustainable AI computing has emerged as a decisive force, reshaping the future of data centers.
IREN’s Dan Roberts joins theCUBE to discuss sustainable AI computing and factory-scale data center strategy.
Rather than treating energy optimization as a constraint, the most forward-leaning operators are turning it into a competitive advantage. Their mission is not merely to host machines, but to industrialize intelligence through infrastructure built to endure, according to Dan Roberts (pictured), co-founder and chief executive officer of IREN Ltd.
“The reality is never take a shortcut because it’ll come back to bite you,” he said. “Build for the long term, build sustainably, build with a long-term perspective [in mind], because that way, you underwrite a reliable platform.”
Roberts spoke with theCUBE’s John Furrier at theCUBE + NYSE Wired: AI Factories — Data Centers of the Future event, during an exclusive broadcast on theCUBE, News Media’s livestreaming studio. They discussed why sustainable AI computing now defines competitive advantage and how AI factories — powered by graphics processing units operating at unprecedented density — are emerging as the new model for scaling intelligence at industrial levels.
Sustainable AI computing belongs to those who can swap, not start over
Unlike legacy facilities built for basic web hosting or enterprise IT, AI factories prioritize rack density, cooling sophistication and power distribution efficiency to maximize computational throughput per square foot. IREN has embraced this model by converting early Bitcoin mining infrastructure into full-scale data centers, purpose-built for AI. Its strategy relies on securing land and energy well in advance of deployment, then rapidly swapping hardware, a move that helps it meet AI’s ever-growing demand patterns, according to Roberts.
“We’ve expanded from 1,900 servers at the end of June,” he said. “Now we’ve got 23,000 either operating or being installed in the coming months, and we’ve got capacity to three times that in short order as well.”
By vertically integrating power access, hardware deployment, and facility operations, IREN avoids the bottlenecks that typically slow hyperscale expansion, all while keeping its eye on sustainable AI computing. Additionally, stainability isn’t just layered onto the model: It’s embedded into the economics, Roberts explained.
“One hundred percent of all power we’ve consumed in the last seven years [has] been from renewable energy sources,” he said. “It’s been an absolute defining part of our business. When you look at the projections for this data center industry, McKinsey is forecasting another 100 gigawatts of data center demand over the next five years, [and] you need to do that sustainably. Our view is go to the source of low-cost renewables and monetize that into [graphics processing unit] cloud.”
