California is seriously limiting the renewable energy its military bases can produce California has kneecapped a formidable ally in the march toward green energy: the United States military. Yes, you read that correctly. The armed forces have become strong proponents of renewable energy over the past decade. Military installations in Southern California have been some of the quickest adopters. And yet, California placed a curious restriction on the amount of renewable energy that military bases in the state can generate. The cap wasn’t included in any of the state’s energy bills. Instead, it was tucked into SB 83, a voluminous budget “trailer bill” passed in 2015. Toward the end of the omnibus bill, after provisions on everything from soccer fields to the Tijuana River, it states that the sum total of renewable energy produced by a single military base in California cannot exceed 12 megawatts. It also denies the military any remuneration for the renewable energy it exports to the grid. I was reporting on the environmental stewardship of Southern California’s bases when I discovered that their efforts were being hobbled. On base after base, generals and other military leaders would refer to the mysterious restriction. “It’s a California thing,” one of them told me.
