EP. 278 Nat Bullard on Decarbonisation in the Age of AI

This week on Energy Unplugged, we’re joined by Nat Bullard, co-founder of Halcyon, an AI-enabled energy information platform, and one of the sector’s most influential data storytellers. He joins Hugo Batten, Aurora’s Managing Director APAC, and Oliver Kerr, Aurora’s Managing Director USA, to unpack the 2026 edition of his annual “Decarbonisation” presentation - a sweeping, data-led assessment of where the global energy transition is accelerating, stalling, and surprising us. Nat brings two decades’ experience analysing energy, technology, markets and finance. Formerly Chief Content Officer at BloombergNEF and now also an advisor to Ember and Arcadia, he draws on deep market insight to separate structural trends from short-term noise. From record solar and battery deployment in the US, to flat real-terms clean investment globally, to China’s extraordinary scale in electrification and manufacturing, the conversation explores a world adding more of everything - fossil fuels and renewables alike - while grappling with grid constraints and rising electricity demand. The discussion also examines cooling demand in developing economies, China’s emergence as a global electrostate, and the profound uncertainty surrounding AI-driven load growth and data centre interconnections in the US - where the bottleneck may be demand connection as much as generation capacity. You will learn: Why the energy transition appears contradictory - with record clean deployment alongside continued fossil growth. How cooling demand in emerging economies could rival or exceed AI as a driver of electricity growth. What China’s scale in electrification, batteries and EVs means for global supply chains and competitiveness. Why grids and interconnection queues may prove the decisive constraint in the next phase of the transition. Registration for the leading annual gathering of the European energy industry – the Aurora Spring Forum, taking place on 29th April 2026, in London is open - a one-day deep dive into the biggest strategic questions shaping Europe’s energy transition, plus top-tier networking and a live recording of Energy Unplugged.
