Fervo Energy Co
A maker of enhanced-geothermal power plants, Fervo Energy uses oil-and-gas drilling techniques — horizontal wells and engineered fractures — to reach hot rock and turn it into round-the-clock, carbon-free electricity. Founded in 2017 by former oil-drilling engineer Tim Latimer and geothermal expert Jack Norbeck, the company supplies power for Google's data centers. Its name comes from the Latin word fervo, meaning "I boil" — fitting for a firm that boils rock to make electricity.
