Guide to Purchasing Green Power: Renewable Electricity, Renewable Energy Certificates, and On-Site Renewable Generation

Updated in August 2018, the Guide to Purchasing Green Power remains the essential resource for renewable energy buyers to understand their options and impact. The Guide provides current and potential buyers of green power with information about green power purchasing. It covers the green power procurement process, different green power supply options, benefits of green power purchasing, as well as information on how to capture the greatest benefit from your purchase. First published in 2004, and previously revised in 2010, this new version of the Guide to Purchasing Green Power provides an overview of green power markets and describes the necessary steps to procure green power. This revision represents a major update to the guide and includes new market information and terminology, updated statistics, new case studies, information on evolving purchasing methods, an updated additional resources section, and new resources for federal agencies and the private sector to use when planning self-generation renewable projects or purchasing green power.

The Guide is the product of a cooperative effort between EPA, the U.S. Department of Energy (DOE), World Resources Institute (WRI), and Center for Resource Solutions (CRS), and the National Renewable Energy Laboratory (NREL).
