Additional Guidance

The Federal Renewable Energy Certificate Guide provides basic information for Federal staff who are new to the concept of renewable energy and renewable energy certificates (RECs), and are seeking to better understand the options for using RECs to meet Federal renewable energy targets. It is intended to assist agencies in understanding the use of RECs to meet the statutory and Executive Order 13693 goals for renewable energy.

Guiding Principle for High Performance and Sustainable Buildings #2 can apply when implementing renewable energy generation projects on agency property for agency use, when lifecycle cost effective.
