Information for Lenders

April 1, 2015

In October of 2013 the American Council for an Energy Efficient Economy (ACEEE) and Energi Insurance Services, with support from the National Renewable Energy Laboratory (NREL), Argonne National Laboratory, and the US Department of Energy (DOE), brought together a group of stakeholders to discuss issues facing small- to mid-size lenders in the energy efficiency space. This gathering was called the Small Lender Energy Efficiency Convening and from this SLEEC was born.

This page is intended to serve as a repository for technical assistance and other relevant information for lenders interested in energy efficiency. Below are links to research reports, blog posts, fact sheets, and webpages, from ACEEE and others brought together in one place to aid and inform those interested the energy efficiency finance marketplace.
