Cindy Taff, chief executive officer of Sage Geosystems, at a testing site in Starr County on March 22, 2023. The startup is testing storing energy in the ground. “There’s some people that believe that there’s a climate crisis, and some people don’t believe it," Taff said. "We want this to be the energy of choice whether you believe in it or not because it’s cost-effective as well.” (Credit: Verónica Gabriela Cárdenas for The Texas Tribune)
