illuminem is proud to present the most-read Thought Leaders in Energy Transition globally, as recognised by illuminem's ever growing community of 700,000+ readers.

The energy transition in 2025 stopped being a story about technology and became a story about power, in both senses of the word. The clean energy build-out continued at pace, but the year's defining theme was the realisation that whoever controls the materials and manufacturing controls the transition itself. China's export controls on rare earth elements and battery components laid the dependency bare: a single country now refines the lion's share of nearly every mineral critical to grids, batteries, and electric vehicles. What had been framed as an engineering challenge was revealed as a geopolitical one.

Against that backdrop, the voices on this list grappled with the transition's hardest questions: how to secure supply chains without stalling progress, how to finance the decarbonisation of utilities and heavy industry, and how to ensure the shift is just as well as fast. From hydrogen's contested role to the lessons of China's clean-energy ascent, they approached the transition not as an inevitability but as a contest whose outcome is still being decided.

What distinguished Noé van Hulst in that conversation was the authority of long experience. As Special Advisor on Hydrogen to the IEA and former Chairman of the IEA Governing Board, he has helped shape global energy policy for decades. His most-read piece made the case for "electrons for peace" – the idea that a clean energy system, built right, could be a force for geopolitical stability rather than a new arena for rivalry.

Joining him on the list, Nicola Armaroli – Research Director at the Italian National Research Council – examines what happens when misinformation and hype around rare earths distort public understanding, Carolyn Kissane – Associate Dean at New York University and Breaking Energy's Top 10 Energy Communicator – explains how China won the clean-energy race, and Venera Anderson – Founder and CEO of Zanpa Edge, a boutique global strategic advisory – traces Japan's green transformation.

Drawn from over 2,500 thought leaders publishing on illuminem Voices, the ranking below reflects the voices that shaped how the energy transition conversation evolved in 2025. Please join us in congratulating the Thought Leaders of the Year in Energy Transition, and every voice contributing to this vital global debate on illuminem.
