Energy Efficiency Grants for Nonprofits come from a mix of sources. Federal grants typically have the largest awards but more competition. State programs often pass through federal funding with state-specific priorities. Foundation grants tend to be smaller but more flexible, with funders looking for organizations whose mission aligns with their giving priorities.
Eligibility varies by funder. Most grants require 501(c)(3) nonprofit status, though some are open to schools, government agencies, businesses, or individuals. Each listing on this page links to the source application where you can find specific eligibility criteria, required documents, and how to apply.
