The Texas-based company has signed an agreement with utility TXU Energy that will see 425 of its stores in the state 100% powered by electricity generated from Texan wind farms.
The agreement starts on 1 June 2018 and will run for eight years.
"Wind energy is a renewable, more cost-effective resource that will lower the carbon footprint of these stores as well as operating costs," said Ben Tison, 7-Eleven senior vice president of development.
"Our customers, particularly millennials and younger Generation Z, care about sustainability and reducing environmental impacts, and they’re paying attention to what companies are doing," he said.
