In this webinar, Vaclav Smil will address with his unmistakable stamp – data, physics and scale – what is feasible and what is fantasy when talking about the rise of AI. It will put numbers to the energy appetite of data centers and generative AI; It will explain what it means in network capacity, cooling and materials, and why thermodynamics, power density and deployment timelines are not circumvented with headlines. It will also look at how to balance security of supply and climate goals without relying on technological “miracles,” and what realistic decisions in investment, public policy, and corporate strategy can sustain digital innovation on a credible energy foundation
