Construction is under way on the Defense Department’s largest solar project ever, Defense One reports.  

“The 155-acre site near the Army base at Fort Huachuca, Ariz., will be outfitted with privately financed solar panels projected to provide more than 18-megawatts of clean power — enough for 25 percent of the base’s needs — as soon as this fall.”  

“The Army has a commitment to the president of deploying one gigawatt of renewable energy by 2025.”
