"The types of financing tools used by State Energy Offices have evolved from revolving loan funds to sophisticated credit enhancement mechanisms and new approaches to bond financing. With successful models expanding across the United States, the National Association of State Energy Officials (NASEO) has completed an analysis of state energy financing programs focused on the buildings and industrial sectors to identify and evaluate approaches that have been implemented by State Energy Offices and their public and private partners."
