The Army breaks ground Friday on a giant solar array at sunny Fort Huachuca in Arizona. Once built, it will provide about a quarter of the energy needed to power the mid-sized base. It will be the largest solar project in the military’s portfolio for a while. Amanda Simpson, executive director for the U.S. Army’s Energy Initiatives Task Force, described the scope of the project to Federal Drive hosts Tom Temin and Emily Kopp.
