Zack Drennen

Zach Drennen


The Rev. Zach Drennen is a native West Virginian with a proven commitment to community development, education, and the environment. Coming from four generations in the coal industry, Zach has always felt that Appalachia is “home”—even when living across the country or overseas.

Zach studied environmental economics at Colorado College, and he later received a Masters of Divinity from Harvard Divinity School. Ordained in 2002, Zach spent two years as a parish priest in West Virginia and three years as a chaplain and teacher at an urban high school in Pittsburgh. In 2007, Rev. Drennen moved to Kenya, where he initiated and ran The Elewana Education Project (EEP), an NGO focused on improving access to essential resources. As part of his work with EEP, Zach spearheaded the development and installation of small solar systems used to power utilities at numerous local schools.

Having determined that it was time to return home to West Virginia in 2015, Zach was eventually appointed president of Rewire Appalachia, an enterprise of Coalfield Development. In this role, he was responsible for training solar installers and managing related economic development and sustainable energy projects. Zach then served as the head of operations at Solar Holler before taking the leap to co-found Revolt Energy with friend and colleague, Keena Mullins.

Zach is married to Lida Shepherd, and they have two daughters, Lucia (6) and Fredi (1).
