## Summary

Christian Belady, former Microsoft VP and creator of the PUE metric, explains that while chip efficiency gains from NVIDIA's Blackwell and Google's Trillium TPUs are significant, Jevons Paradox ensures total energy demand will rise as compute becomes cheaper and more capable. He argues that power availability, alongside labor and supply chain constraints, is now the primary bottleneck for AI growth, making it impossible to simply plug in gigawatt-scale data centers. Belady advocates for integrated demand response models, citing a 2016 Microsoft project at Cheyenne, and calls for deeper collaboration between hyperscalers and utilities to manage grid constraints. Finally, he introduces the concept of 'nature-positive' data centers, which aim to improve local ecosystem health rather than just minimizing carbon emissions.
