When it comes to clean energy, we often hear about wind and solar, but there are other, perhaps less-talked about, renewable sources to include in our energy transition portfolio. In this episode, we focus on geothermal, which uses heat from the earth to generate energy. You may have heard of the Geysers in northern California, the world’s largest geothermal field, or the Salton Sea in southern California, the second largest geothermal field in the U.S. However, in 2022, just 0.4% of U.S. electricity generation came from geothermal energy. Can we harness the potential of the earth’s heat in more than just volcanic regions? 

To address this question, Justine and Paulina speak with Dr. Birendra Jha, a professor of petroleum engineering at USC who runs a research group, the GEM Lab, which aims to address engineering challenges related to energy. We talk about what geothermal energy is, why geothermal seems to be less popular than other sources like wind and solar, and the challenges and benefits of an emerging technology, Enhanced Geothermal Systems (EGS), which could expand where geothermal energy is produced.

Jim then speaks with Minh Tran, a geothermal engineer with a PhD in Petroleum Engineering from USC, who is studying ways to more effectively transform geothermal heat into electricity. We talk about whether skills from oil and gas are transferable to geothermal, the potential of EGS in the energy transition, and the importance of financing and policy incentives in expanding geothermal.
