This directory offers a compendium of more than 65 energy-efficiency funds operating throughout the world, from Slovakia to South Carolina. It provides a variety of information about each fund, including interest rates, loan terms, minimum and maximum loan amounts, types of projects, and contacts. Although most are loan (debt) funds, the list also presents a limited number of loan guarantees and equity investment funds.
