The Green Power Partnership works with a wide variety of leading organizations — from Fortune 500 companies to local, state and federal governments, and a growing number of colleges and universities. The following Top Partner Rankings highlight the annual green power purchases of leading organizations within the United States and across individual industry sectors.

These green power purchases help reduce the environmental impacts of electricity use and support the development of new renewable generation capacity nationwide. Purchase amounts reflect U.S. operations only and are sourced from U.S.-based green power resources. Organizations can meet EPA purchase requirements using any combination of three different product options (1) Renewable Energy Certificates, (2) On-site generation, and (3) Utility green power products.
