Welcome to the Clean Energy for Low-Income Communities Accelerator (CELICA) Toolkit. This toolkit provides an overview of tools, resources, and models for developing low-income energy efficiency and renewable energy programs based on work in the U.S. Department of Energy’s CELICA, part of the Better Buildings Initiative Accelerators. This toolkit provides materials to help program administrators reduce energy burden for low-income communities by enhancing and expanding upon work funded through utility, state, or federal programs. These materials are the product of CELICA’s two-year partnership with over 30 stakeholders from the public, private, and nonprofit sectors and does not provide Energy Department-funded program guidance. An overview of the various tools and resources within the CELICA Toolkit and a summary of individual CELICA partner accomplishments can be found in the CELICA Overview Document.
