Geothermal 101: Unlocking Iceland’s Energy with Kári Valgeirsson
What’s the secret behind Iceland’s warm homes, steaming hot tubs, and even those snow‑free driveways in the middle of winter? The answer lies just beneath the surface: geothermal energy.
In our latest Lava Academy Podcast episode, we sit down with Kári Valgeirsson, geologist and science communicator at the The Geothermal Exhibition at Hellisheiði Geothermal Power Plant, only a short drive from Reykjavík. Kári brings complex science to life, showing how Iceland turns volcanic heat into clean, renewable energy.
Why You Should Listen
This episode is packed with fascinating insights:
Geothermal explained: What it is, how it works, and why it’s different from other renewables.
A history of innovation: How Iceland rapidly shifted from oil dependence in the 1970s to becoming a world leader in clean energy today.
Future breakthroughs: Learn about cutting‑edge projects like the Krafla Magma Testbed, which could multiply geothermal output tenfold.
Everyday impacts: From heating homes and pools to inspiring sustainable energy models worldwide, geothermal is at the heart of Icelandic life.
The Bigger Picture
Geothermal isn’t just an Icelandic story—it’s a global opportunity. With the right technology and investment, many regions could harness the same energy that fuels Iceland’s daily life. As Kári points out, geothermal can help countries lower emissions, stabilize energy supply, and rethink how we power our future.
