Everything Energy

When you think of batteries, you might picture charging a phone or laptop. But it’s the energy industry that has transformed the battery market over the past decade. Today, over 90% of battery demand comes from the energy sector, driven by record-breaking electric car sales and the rapid growth of battery storage to support power grids around the world.

In this episode, we hear from Teo Lombardo, an IEA analyst specialising in batteries, and Araceli Fernandez Pales, the head of the IEA’s Technology Innovation Unit. They explain how batteries work and their role in modern energy systems, as well as why prices have fallen dramatically in recent years and what innovations could drive further growth.

Oil markets have faced significant turbulence this year. Heightened geopolitical risks, trade tensions and policy shifts have all affected the outlook. At the same time, the major drivers of supply and demand over the past 15 years are losing momentum, signalling that a deeper transformation of markets is underway.

In this episode, Toril Bosoni, Head of the IEA’s Oil Industry and Markets Division, unpacks the latest developments, speaking about the forces shaping oil markets today, how resilient they could be to tensions in the Middle East and elsewhere, and what the oil market might look like in the years ahead.

For the past 10 years, the IEA’s World Energy Investment report has been the definitive guide to where money is going in the global energy sector. It breaks down the latest data for all the key fuels, technologies and industries.

In a context of heightened geopolitical and economic uncertainty, global energy investment is set to reach a record $3.3 trillion in 2025. In this episode, we’re joined by Cecilia Tam, Head of the IEA’s Energy Investment Unit. She unpacks the report’s key themes – from how energy security concerns are driving investment decisions, to China’s position as the single biggest investor in energy, and why so much money is going into electricity.

The automotive industry has faced major challenges in recent years, from pandemic-driven supply chain shocks to inflation and geopolitical uncertainty. But amid the turmoil, global sales of electric vehicles have continued to break records. 

In 2024, more than one in five cars sold globally were electric, and this year it's expected to be one in four. In some parts of the world, EVs are now cheaper than conventional cars. But what's driving these trends? Who's making these cars? How are we charging them? And how is their uptake reshaping the world’s energy system? 

In this episode, we speak with IEA Energy Technology and Transport Analyst Elizabeth Connelly to answer these questions and unpack the 2025 edition of the IEA's annual Global EV Outlook, out now.

While the history of artificial intelligence is long, ChatGPT’s public launch in late 2022 captured the world’s attention and pushed AI to the top of business and political agendas. Just a few years later, AI has evolved into an industry worth trillions of dollars that is already transforming how we live and work. Yet any conversation about the future of AI inevitably leads to the topic of energy.

In this episode, host Dan Hewitt speaks with Thomas Spencer and Siddharth Singh, lead authors of the IEA’s groundbreaking new report, Energy and AI. They unpack why the huge expectations for AI hinge on meeting fast-growing demand for electricity from data centres, and how the IEA developed authoritative global projections for AI’s energy demand over the next decade. They also describe the ways AI is already transforming the energy sector, as well as AI’s implications for energy security and global emissions.

This year, electricity generated from nuclear power is set to reach a record high. Dozens of nuclear reactors are currently under construction, and government support for the sector is at its highest level since the oil crisis in the 1970s. These trends point to a major global comeback for nuclear energy after a prolonged period of stagnation.

In this episode, host Dan Hewitt is joined by Brent Wanner, the head of the IEA’s Power Sector Unit. Drawing on important findings from a recent IEA report, The Path to a New Era for Nuclear Energy, they discuss the factors driving nuclear energy’s renewed momentum. They also dig into the key challenges, such as project delays and cost overruns, that need to be overcome for it to play a more significant role in the future energy landscape.

It's abundant. It's clean. And it’s right beneath our feet. So why is geothermal energy often overlooked in the global energy conversation?

Despite its massive potential, geothermal only meets about 1% of global electricity demand today. So, what’s holding it back? And could new technologies transform the way we think about geothermal energy and who can access it?

Joining host Dan Hewitt to explore these questions are Heymi Bahar and Rebecca Schulz, senior analysts at the International Energy Agency and co-authors of the IEA’s latest report on the subject, The Future of Geothermal Energy.

What does the world of energy look like today? In this episode of the IEA’s Everything Energy podcast, which is back from an extended break, we delve into this topic, guided by a brand-new IEA report.

The Global Energy Review 2025 is the first assessment of 2024 trends across the energy sector based on the latest data. It shows that growth in energy demand surged in 2024 to almost twice its recent average as the consumption of electricity rose around the world. 

Why is this so significant? What fuels and technologies helped meet the increase in demand? And what has been the effect on global emissions? Host Dan Hewitt and Laura Cozzi, the IEA’s Director of Sustainability, Technology and Outlooks, discuss these questions and more.

In this episode of the podcast we welcome Brian Motherway, Head of Energy Efficiency back to the studio to reflect on the worrying trend in efficiency gains this year, as a result of the economic impacts of the Covid-19 crisis. Brian takes us through the importance of efficiency in sustainable, resilient recovery plans and clean energy transitions, and also talks to us about the IEA's relatively new focus on behavioural changes and energy efficiency.
