Tortoise's Thummel on why natural gas will help the U.S. win the global A.I. race

Rob Thummel, Senior Portfolio Manager at Tortoise Capital, says that for all of the power needs created by artificial intelligence, producers still need their power costs to be reasonable, and he expects that natural gas will lead the way going forward. Thummel, who runs Tortoise Energy Infrastructure fund, says current conditions for energy infrastructure remain the most favorable he has seen in 30-plus years as a portfolio manager, largely because energy is "the foundation of the A.I. five-layer cake" famously described by Nvidia president Jensen Huang. Thummel says that while investors have been light on energy allocations historically, this would be a bad time to be underweight energy, because positive conditions are setting up tailwinds that could last for years.
