Sriram Vasantharajan is the President and CEO of Mazama Energy, a Khosla Ventures and Gates Frontier-backed startup drilling into Oregon's Newberry Volcano to prove that superhot rock geothermal can deliver round-the-clock, carbon-free power at fossil-fuel prices. A former ExxonMobil engineer and CEO of oilfield services firm Blade Energy Partners, he is now applying decades of drilling and well-stimulation know-how from the oil patch to the geothermal industry, chasing rock hot enough to make a volcano's flank into a power plant.
Tim Latimer is the co-founder and CEO of Fervo Energy, the company that took horizontal drilling and fiber optic sensing out of the shale fields and pointed them straight down into hot rock. A former oil-and-gas drilling engineer who grew up next to the last coal plant built in America, he left the industry, talked his way into Stanford, met a geothermal PhD named Jack Norbeck, and bet that geothermal could become 24/7 carbon-free power at utility scale. Fervo has since raised over a billion dollars, broken drilling records once thought decades away, signed Google as a customer, and gone public on the Nasdaq in 2026 while building Cape Station, the world's largest next-generation geothermal project.
