Through the United States Agency for International Development (USAID), the Government of the United States provides funding to the Private Financing Advisory Network (PFAN), a programme hosted by UNIDO and REEEP.

Previously, the U.S. Department of State, through the Asia-Pacific Partnership on Clean Development and Climate, funded the creation of a Compendium of U.S. Best Practices, a guidebook of best practices in renewable energy from the state and city level in the United States.
