Geothermal energy is having a moment. As demand for reliable, always-on power grows alongside data centers and electrification, new drilling technologies are unlocking geothermal's potential far beyond its traditional strongholds in California, Nevada, and Iceland. In part one of this two-part series, host Sebastian Duque Rios sits down with Tom Lutken, science fellow at the Environmental Law Institute, for a primer on how geothermal energy actually works — and what's changing.

We break down the science behind geothermal electricity generation, the difference between direct-use applications and power generation, and next-generation technologies like enhanced geothermal systems, advanced geothermal systems, and super-hot rock geothermal that are expanding where geothermal can be developed. The conversation also covers drilling costs, potential risks, and innovative approaches aimed at solving geothermal's biggest cost barrier.

The episode closes with a preview of the regulatory landscape shaping geothermal's growth with Susannah Dibble, staff attorney at ELI. From the decades-old Geothermal Steam Act to the state-level legislation now playing catch-up with the technology, we highlight some of the major financing, legal, and policy questions surrounding geothermal that merit further analysis. The second part of this series digs deeper into these issues with a full panel of experts.
