Renewable Energy

Renewable Energy Handbook (.pdf 2.2Mb)

The Army needs to satisfy multiple goals and constraints while securing its energy supplies — focusing upon procurement of the lowest-cost energy that meets high reliability standards and minimum vulnerability to interruption from natural or intentional causes. Overlaid on this challenge is the need to comply with a series of statutes and policies as summarized below. These include:

The table below summarizes these statutes and policies.

  EPAct Section 203 Executive Order 13423 National Defense Authorization Act (2007)
Target/Goal Increasing targets reaching 7.5% renewable content of electricity consumed At least 7.5% of electric energy from new renewable energy with at least 50% from new renewable sources (after 1998) 25% of all energy consumed from renewable sources of supply
Target Dates 2013 Yes No
Mandatory? 2013 Yes Yes
Considers thermal energy "renewable?" 2025 No Yes

Guidance and Interpretation of Goals

The Department of Energy (DOE) is responsible for developing guidance for EPAct 2005 and EO13423. DOE's guidelines for EO compliance allow credit for renewable energy that reduces electricity use from thermal sources; however DOE adds a requirement that at least 50% of renewable energy must come from "new" resources; those put into service after January 1, 1999. DOE's guidance for EPAct 2005 is that renewable energy that is not electricity, such as solar thermal energy, daylighting, or ground source heat pumps, cannot be credited towards the EPAct 2005 goals. Congress did not provide a definition of "renewable" in the NDAA 2007 language, and DOE is not responsible for establishing DoD or Army policies to achieve the goals in the NDAA.

Guidance from the Army including practical information on renewable energy technologies is available in the Renewable Energy Handbook for Installations (.pdf 2.2Mb) .

The current Army energy strategy for renewable energy takes an expansive view of renewable energy that encompasses thermal energy from renewable sources. As a result, the Army is developing a strategy and implementing projects to satisfy Congressional, Administration, and DoD mandates and directives. The expectation is that the Army will meet the stricter definitions of EPAct 2005 on its way to meeting the much higher renewable energy goals of the NDAA 2007.
