All Heat, No Useful Work

The Amp Hour · 25 May 2026 · 1h 05m · Episode 724

What this episode covers

Dave Jones and Chris Gammell discuss the massive energy demands and infrastructure challenges of AI data centers, noting that 100% of input power becomes heat and requiring extensive cooling and diesel backup. They cover supply chain constraints, including a three-year backlog for transformers and a 40% surge in bareboard PCB prices driven by AI server demand. The conversation shifts to practical electronics work, where Chris details building a power-injecting Tag-Connect debug board and using Claude to implement SMP firmware updates over web serial, while Dave shares his frustration with a solar monitoring service's price hike and his son's struggles with Linux at school.

    EP 186: Mobile Bottlenecks, Skyrocketing AI CapEx, and the Compute Crunch

    Hosts Ben Bajarin and Jay Goldberg analyze recent earnings from Apple, Qualcomm, ARM, and MediaTek, highlighting severe mobile supply chain bottlenecks and soft demand driven by elevated memory costs and foundry capacity constraints. They discuss skyrocketing hyperscaler CapEx from Amazon, Microsoft, and Meta, focusing on the transition from AI training to inference, the rise of behind-the-meter power solutions like Bloom Energy, and critical labor shortages in electrical trades. The episode concludes with an examination of market volatility linked to hedge fund unwinds and the increasing reliance on debt financing for data center expansion.

    The state of play of data center development

    Chris Sharp, CTO of Digital Realty, explains that AI inference workloads are clustering in existing availability zones like Northern Virginia due to latency and throughput requirements, creating 'data gravity' that drives regional growth. He details how grid interconnection delays and equipment bottlenecks, such as 50-week transformer lead times, are extending project timelines beyond the standard two years. Sharp also discusses the role of 'bridge power' and diesel generators as necessary short-term solutions to meet SLAs while waiting for grid upgrades, noting that liquid cooling increases reliability demands rather than reducing them.

    Navigating the electricity gauntlet

    Andy Lubershane, partner and head of research at Energy Impact Partners, joins Shayle Khan to discuss the 'electricity gauntlet,' where surging power demand from data centers, battery manufacturing, and EV charging collides with supply chain bottlenecks and regulatory hurdles. They analyze how the flatlining of electricity demand over the past two decades is ending, driven by new industrial loads like green hydrogen and generative AI, which are straining utility capacity. The conversation highlights critical short-term challenges, including a severe shortage of electrical transformers, interconnection queues, and the need for microgrids and carbon-future-proofed gas generation to bridge the gap until renewable firming technologies scale.

    Frontier Forum: An energy-first approach to data centers

    Chase Lochmiller, co-founder and CEO of Crusoe Energy Systems, discusses the company's shift from mitigating gas flaring to building gigawatt-scale, energy-first data centers for AI. He explains how Crusoe leverages stranded renewable energy in locations like West Texas and Iceland to power its 'climate-aligned cloud' and GPU clusters. Lochmiller identifies power availability, not chip supply, as the primary bottleneck for AI scaling, citing the immense energy demands of Nvidia's H100 and Blackwell chips. He highlights engineering challenges in cooling, labor shortages, and the potential for data centers to become net carbon-negative through innovations like direct air capture.

    Can chip efficiency slow AI's energy demand?

    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.
