  • Can chip efficiency slow AI's energy demand?
    Jul 18 2024
    In March, Nvidia announced a new microchip designed for AI that is 25 times more energy efficient than its predecessor. Two months later, Google announced one with a 67% efficiency improvement. Today, the rest of the semiconductor industry is hyper focused on efficiency gains. Will they save us from ballooning data center energy demands? In this episode, Shayle talks to Christian Belady, former Microsoft vice president now focusing on data center advanced development. They unpack concerns about this new surge of demand and whether it’s different from the energy scare two decades ago. Back in 1999, researchers predicted that data centers could end up consuming half of U.S. electricity. But instead, demand remained largely flat at about 4% as cutting-edge hyperscale cloud computing displaced inefficient, on-premises servers. And yet, driven by the AI boom, energy concerns are back. The Electric Power Research Institute predicts that data center loads could consume 9% of U.S. power generation by 2030. Demand is already rising fast, with emissions at both Google and Microsoft up significantly. Shayle and Christian examine the factors driving those trends and what we can do about it, covering topics like: Whether chip efficiency improvements will lead to energy savings or just more powerful computing The upper limits of Moore’s Law Energy, labor, and other big constraints on AI growth Changing computing architecture to find energy savings Enlisting data centers in integrated, or compulsory, demand response Using AI to improve chip design Recommended resources Fierce Electronics: Power-hungry AI chips face a reckoning, as chipmakers promise ‘efficiency’ Latitude Media: The data center of the future looks like a massive virtual power plant Latitude Media: Enchanted Rock is selling utilities on flexible data center connection Latitude Media: Energy is now the ‘primary bottleneck’ for AI Catalyst: Under the hood of data center power demand Catalyst is brought to you by Kraken, the advanced operating system for energy.

  • The reshoring of American solar trackers [partner content]
    Jul 17 2024
    While we were all at home during Covid desperately trying to get our hands on toilet paper, exercise equipment, and home furnishings, solar executives like Dan Sugar were trying to get steel and power electronics to massive PV farms under development. As equipment and workforce disruptions spiraled due to lockdowns, the cost of installed solar started going up for the first time in nearly a decade. “Costs just skyrocketed. And so at this point in my career. I wasn't going to proceed like that,” explained Shugar, the CEO of Nextracker, the world’s top solar tracking company. It became very obvious that Nextracker had to build more US manufacturing to serve local markets, where utility-scale PV was still booming. And within a couple years, they built a large network of factories. “We've catalyzed over 20 factories across the United States with over 30 gigawatts of major components being manufactured here and shipping finished goods today. That's just a huge retooling of the supply chain,” explained Shugar. To date, Nextracker has shipped 100 gigawatts of trackers. More and more of them are being produced in key locations around the US. In this episode, produced in collaboration with Nextracker, Stephen Lacey speaks with Dan Sugar about progress in onshoring, innovations in tracker technology, and where the solar industry is headed next. Learn more about Nextracker’s efforts to bolster domestic content for solar power generation in the US.

  • Decarbonizing the high seas
    Jul 12 2024
    While aviation may be converging on one main pathway to decarbonization — sustainable aviation fuel — maritime shipping may require a more diverse set of solutions: a portfolio of fuels, energy efficiency, and on-board carbon capture and storage. But each technology has operational and capital challenges. So what will it take to scale them up? In this episode, Shayle talks to Dr. Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation. Ocean-going shipping consumes about 300 million tons of fuel per year, accounting for 3% of global emissions. But with significant regulatory pressure from bodies like the International Maritime Organization, shipping companies are exploring a range of options. Shayle and Lynn cover topics like: Conventional fuels, like heavy fuel oil and marine gas oil The inadvertent climate impact of cutting sulfur emissions The pros and cons of lower-carbon fuels, like LNG, biofuels, methanol, and ammonia The challenges for infrastructure and operations, especially involving the low volumetric energy density of new fuels On-board carbon capture and storage How energy efficiency reduces the impact of low volumetric energy density Recommended resources International Maritime Organization: Fourth Greenhouse Gas Study 2020 Catalyst: Heavy duty decarbonization Catalyst: Putting a halt to geoengineering — by accident Catalyst is brought to you by Anza Renewables, a data, technology, and services platform for solar and storage buyers.

  • Under the hood of data center power demand
    Jun 13 2024
    Driven by the AI boom, data centers’ energy demand could account for 9% of U.S. power generation by 2030, according to the Electric Power Research Institute. That's more than double current usage. So how do we meet that demand? And what impacts will it have on the grid and decarbonization? In this episode, Shayle talks to Brian Janous, former vice president of energy at Microsoft and current co-founder of Cloverleaf Infrastructure. Brian talks through the options for meeting data center demand, including shaping computational loads to avoid system peaks and deploying grid-enhancing technologies. He and Shayle also cover topics like: Why AI-driven demand will be big, even with “zombie requests” in the interconnection queue How hyperscalers are “coming to grips” with the reality that they may not hit decarbonization targets as quickly as planned Why Brian thinks efficiency improvement alone “isn’t going to save us” from rising load growth Why Brian argues that taking data centers off-grid is not a solution Options for shaping data center load, such as load shifting, microgrids, and behind-the-meter generation How hyperscalers could speed up interconnection by shaping computational loads Recommended Resources: Electric Power Research Institute: Powering Intelligence: Analyzing Artificial Intelligence and Data Center Energy Consumption The Carbon Copy: New demand is straining the grid.

  • Heavy duty decarbonization
    May 30 2024
    Batteries are making their way into more passenger cars and commercial vehicles than ever before, but the limits of electrification mean that we’ll likely need alternative fuels to decarbonize heavy transport like ships, planes, and trucks. So what are those fuels and what modes of transport do they suit best? In this episode, Shayle talks to his colleague Andy Lubershane, partner and head of research at Energy Impact Partners. They talk through the limits of electrification and the alternatives for decarbonizing trucks, ships, and planes, drawing on Andy’s recent blog post, “How will we move the big, heavy things?”. They cover topics like: The main limitations of batteries: density and infrastructure Volumetric and gravimetric density, and why they matter for different types of vehicles How fossil fuels would beat out even a theoretical “uber-battery” multiple times denser than current batteries Why upgrading “always-on” grid infrastructure can be lengthy, expensive, and disruptive The alternatives to electrification: biofuels, hydrogen, and e-fuels The advantages and limitations of each for different modes of transport Recommended Resources: Port of Long Beach: Our Zero Emissions Future Enterprise Mobility: Electrifying Airport Ecosystems by 2050 Could Require Nearly Five Times the Electric Power Currently Used Catalyst: Understanding SAF buyers Utility rates could make or break the energy transition – so how do we do it right?
