The Army Energy Security and Sustainability Strategy; Maintaining Operations in a Challenging Environment

Today’s post was written by  the Honorable Katherine Hammack, Assistant Secretary of the Army (Installations, Energy and Environment)


The Army is celebrating our 240th birthday ( As the Army stands ready and continues to serve, we must be able to accomplish our missions in a world defined by uncertain, adverse, and dynamic conditions. Maintaining our strategic edge heavily depends on our wise use of resources-energy, water, and land.

The Army works to efficiently manage our installation boot print, striving to reduce risk to our critical missions. One example of risk to our installations is power disruption. Installations and surrounding communities are experiencing increased power outages due to the impact of natural disasters and a vulnerable electrical distribution system. In the last 10 years, we have seen over a four-fold increase in power interruptions on our Army bases.

Energy supply shortfalls and power distribution failures, coupled with water scarcity, represent a strategic vulnerability for the Army – increasing risk to missions. To maintain operations in this challenging environment, just last month the Army released our Energy Security and Sustainability (ES2)Strategy.

ES2 envisions a ready and resilient Army, strengthened by secure access to energy, water, and land resources-conditions which preserve future choice in our rapidly changing world. The objective is to enhance Army capabilities, readiness, and performance through effective system design and integration of resource considerations into behaviors and decision processes.

In essence, ES2 represents a turning point for the Army. The Army is evolving from a historic framework that viewed resource considerations as constraints on operational effectiveness, to a perspective that considers the critical role of energy, water, and land resources as mission enablers.

Our strategy will guide the Army to reduce future resource risk and increase mission assurance, providing a pathway that is focused, first and foremost on mission capability. Of course, an effective strategy needs goals to measure performance, so we have organized ES2 into five strategic goals.

The First goal is energy and sustainability to enable informed decisions; secondly, we must optimize the use of our resources; third, we must assure access and freedom of maneuver for our forces; fourth, we must improve resilience to maintain operations in our ever-changing environment; and finally, we must drive innovation to identify opportunities.

The Army’s ES2 strategy is designed to guide the Army’s use of energy, water and land resources well into the 21st century. I believe that by working through industry and community partnerships we will be capable of addressing many of these challenges and ensure Army installations are the readiness platforms for winning in a complex environment, through 2025 and beyond.


Army Strong!

The Honorable Katherine Hammack
Assistant Secretary of the Army – Installations, Energy & Environment

The Honorable Katherine Hammack was appointed the Assistant Secretary of the Army for Installations, Energy and Environment (ASA IE&E) by President Obama on June 28, 2010. She is the primary advisor to the Secretary of the Army and Chief of Staff of the Army on all Army matters related to Installation policy, oversight, and coordination of energy security and management.

She is responsible for policy and oversight of sustainability and environmental initiatives; resource management, including design, military construction, operations, and maintenance; base realignment and closure (BRAC); privatization of Army family housing, lodging, real estate, and utilities; and the Army’s installations safety and occupational health programs. Among her many accomplishments are the establishment of the Army’s Net Zero program, and the creation of the Office of Energy Initiatives (OEI), which is working to streamline large-scale renewable energy projects to achieve 1GW of renewable energy by 2025.
