NREL and Army Partner to Achieve Net Zero Energy

NREL and Army validate energy savings for net zero energy installations, November 4, 2014

The U.S. Army has partnered with the Energy Department’s National Renewable Energy Laboratory (NREL) to increase energy security through improved energy efficiency and optimized renewable energy strategies at nine installations in the Army’s portfolio. If all nine of the Army Net Zero Energy Installation (NZEI) pilot sites achieve net zero energy, they will replace approximately 8 percent of the Army’s current total installation energy use with renewable energy. In fact, if all Army installations worldwide were to achieve a 25 percent reduction in energy consumption, as the NZEI pilot sites can, the Army would save approximately 20 trillion BTUs and up to $300 million in annual energy costs.

The NZEIs studied by NREL employed technologies that can be replicated across the Department of Defense and other federal agencies, setting the stage for broad market adoption. The Energy Department’s Federal Energy Management Program has been supporting this project’s implementation and replication efforts.

“It’s been exciting to be a part of the net zero energy journeys of so many installations and to see the variety of approaches,” NREL Project Leader Sam Booth said. “For example, Fort Hunter Liggett is on track to achieve net zero energy largely through many small projects, while Kwajalein is focused on achieving its net zero goal through a single large project.”
