Solar Array Ribbon Cutting
Solar panels collect sunlight at Davis-Monthan Air Force Base, Ariz. The Davis-Monthan solar array project is placed on 170 acres of underutilized land, making this the largest of its kind on any U.S Department of Defense installation. The Air Force has stated a goal to increase renewable energy consumption to 25 percent throughout the Air Force by 2025. (U.S. Air Force photo by 1st Lt Sarah Ruckriegle/released)
