Geothermal Power Faces Debate Over Scaling Up Amid Rising AI Energy Needs

Addy Smith and Michael Barnard present opposing perspectives on geothermal’s future. Smith sees an inflection point, citing constant AI and data-center power needs, recent drilling technology borrowed from oil and gas, and a growing network of investors and policymakers that could lift geothermal from niche status. Barnard warns that expensive drilling, variable reservoir performance, and a lack of proven large-scale replication still hamper electricity production, positioning geothermal heat for district-heating and industrial processes as the more realistic short-term market.

Both agree that interest in the sector has surged, but they differ on whether the sector is ready for widespread power generation or should focus on thermal applications first. The dialogue reflects broader questions about how best to meet clean-energy targets as digital workloads expand.
