AUSA’s Institute of Land Warfare recently released a new publication, "U.S. Army Energy Security Strategy and Sustainability: Vital to National Defense" (Torchbearer National Security Report, April 2011), which examines the Army’s efforts to build energy security, diversification and sustainability throughout the force.Increasing pressure on natural and man-made resources is requiring the Army to adapt and innovate to provide warfighters with the energy and power needed to win on complex battlefields.The Army is employing a force-wide strategy that addresses modern challenges to energy, water and waste in a sustainable manner.The main component is the Net Zero strategy, which focuses Army installations on reducing resource demands, recycling and repurposing waste and incorporating renewable energy into operations.Net Zero is coupled to an enabling hierarchy that pairs simple steps that can be taken immediately with long-term goals and projects.The Army is also addressing the traditionally challenging area of tactical power.Smart micro-power grids, advanced insulations, solar battery chargers and fuel blending are just a few of the efforts underway in operational theaters to reduce the logistical and operational burden of supplying the expeditionary force.The current Army strategy is preparing for long-term success in resource sustainability by tackling operational issues at their root causes and embracing a range of partnerships to bring the latest technology and solutions to the force.This report and other ILW publications are available online at http://www.ausa.org/ilw, and can also be obtained by calling (800) 336-4570, Ext. 630, or by e-mailing a request to ilwpublications@ausa.org.
