About Clean Energy Grants for Nonprofits
Nearly half of clean energy grants for nonprofits require cost-sharing partnerships, a distinctive funding reality that shapes strategy from the start. 5,305 active grants in this category reflect this investment-intensive landscape, with the Advanced Research Projects Agency Energy leading as the top funder alongside the Idaho Field Office and Office of Science.
Award amounts typically range from $500K to $15.0M, with 94% of grants using competitive application processes. Most support research, programs, and capital projects. Since cost-sharing requirements significantly impact feasibility, filtering by support type—particularly Research versus Program grants—can help identify opportunities that align with your organization's capacity and partnership infrastructure.
