About this episode
Critical minerals are essential for many of today’s energy technologies – and for the broader economy. Lithium, nickel, cobalt, manganese and graphite, for example, are crucial to battery performance. Rare earth elements are indispensable for the permanent magnets in wind turbines and electric vehicle motors. And electricity networks need huge amounts of aluminium and copper. As demand for these materials rises rapidly, so does their strategic importance.
But in recent years, critical mineral supply chains have become more concentrated, not less – demanding greater attention from policymakers and industry. This episode features conversations with Benjamin Gallezot, the critical minerals envoy of France – which holds this year’s G7 Presidency – and Jakob Stausholm, the former CEO of multinational mining group Rio Tinto. Speaking on the sidelines of the IEA’s 2026 Ministerial Meeting in February, they discuss the growing importance of critical minerals for global energy and economic security – and what steps could be taken to strengthen supply chain security and resilience. Tae-Yoon Kim, the head of the IEA’s Critical Minerals Division, also joins the episode to share the latest data and analysis on the subject, as well as how the IEA is bringing countries together to tackle supply risks.

The rise of air conditioning – and push to improve it
Invented at the turn of the 20th century to control humidity at a New York printing plant, the air conditioner has reshaped the economies and societies that have had access to it. Today, more than 1.5 billion AC units are in use around the world – and as incomes and temperatures rise, demand continues to grow rapidly. But there are challenges associated with this air conditioning boom. If a city’s residents all turn on their ACs at the same time, the resulting surge in electricity consumption can strain power grids. Growing electricity demand from air conditioning also contributes to higher energy sector emissions. That’s why innovators are working to improve cooling technologies, be it by making air conditioners more efficient or by developing entirely new systems to help people stay cool. This is the final episode in a three-part miniseries on energy innovation stories that changed the world. It is hosted by Dan Hewitt and produced by Dan Hewitt and Julia Horowitz. Guests include IEA analysts Chiara Delmastro and Simon Bennett; Eindhoven University of Technology Professor Daniel Barber; Blue Frontier Co-founder and CEO Daniel Betts; and University of Cambridge Professor and Barocal CEO Xavier Moya.Read more -
How drilling technologies have shaped the energy landscape
Technological advances in drilling have had a profound impact on our economies and societies, unlocking vast energy resources underground. The first commercial oil well in 1859 paved the way for the modern oil industry, and more recent breakthroughs have repeatedly reshaped global energy dynamics. Innovation in drilling technologies continues today. Some of these technologies have helped lay the basis for next-generation geothermal energy projects, which could unlock heat as a reliable and low-emissions energy resource in many parts of the world. This episode is the second in a three-part miniseries on energy innovation stories that changed the world. It is hosted by Dan Hewitt and produced by Dan Hewitt and Julia Horowitz. Guests include IEA energy analyst Courtney Turich; Sjoerd Brands, technical manager in Europe for well construction at SLB; Iain Hutchison, Chief Executive Officer of Merlin Energy; and Kristie McLin, Principal Investigator of the Utah FORGE project.Read more -
The innovation story behind today’s solar power boom
Today, solar PV is the fastest-growing energy source in the world. Yet that would not have been possible without a history of innovation spanning decades. From the breakthrough discovery of a practical silicon solar cell at a US phone company in the 1950s to the rapid scaling up of solar panel manufacturing in China in the 2000s, these advances – along with supportive policies – have made solar energy cost competitive globally. And innovation could now reshape the sector once again, helping address emerging challenges such as grid integration and supply chain concentration. This episode is the first in a three-part miniseries on energy innovation stories that changed the world. It is hosted by Dan Hewitt and produced by Dan Hewitt and Julia Horowitz. Guests include IEA energy technology analyst Simon Bennett; Sekisui Chemical Co. group leader Takeru Bessho; Qcells Global Chief Technology Officer Danielle Merfeld; and Greg Nemet, professor at the University of Wisconsin-Madison and author of the book “How Solar Energy Became Cheap.”Read more
