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.
