The deputy secretary of the U.S. Department of Energy met Wednesday in Flagstaff with Navajo and Hopi leaders to discuss an unprecedented federal investment in solar energy for tribal homes.

The Navajo-led nonprofit Native Renewables received an 8 million dollar grant to install off-grid, battery-powered solar systems in Navajo and Hopi homes. It’s part of a $366 million clean energy package for twenty states and thirty Tribal nations announced this week by the Biden Administration.
