Clean Energy & Climate grants: common questions

How many clean energy & climate grants are available right now?

GrantSonar is tracking 121 open clean energy & climate grants as of today. That count reflects opportunities that are currently accepting applications — closed rounds and award announcements are excluded, which is why it is smaller than the headline figures some directories advertise. Federal, state and foundation sources are re-ingested daily.

Who funds clean energy & climate grants?

The most active funders behind the 121 open clean energy & climate grants on this page are U.S. National Science Foundation, NASA Headquarters and Santa Monica Mountains Conservancy. Foundation funders are profiled from public IRS Form 990 / 990-PF filings, so you can see a funder's actual past giving rather than only its stated priorities.

Who is eligible for clean energy & climate grants?

Eligibility for clean energy & climate grants varies by opportunity, but the listings on this page are open to nonprofits, government agencies, school districts and other eligible organizations. Each listing states its own eligible applicant types, and GrantSonar filters your matches against your organization type, geography and programs so ineligible opportunities are demoted rather than surfaced.

When are the deadlines for clean energy & climate grants?

Deadlines differ per opportunity and some are rolling with no fixed close date. Every listing on this page shows its own close date where the funder publishes one, and GrantSonar re-checks source pages so a deadline that moves is picked up rather than left stale.

Is there a free way to search clean energy & climate grants?

Yes. This page is free to browse with no account. A free GrantSonar account additionally matches these clean energy & climate grants against your organization's profile and eligibility, so you get a ranked shortlist rather than a list you filter by hand.

How often is this list of clean energy & climate grants updated?

Daily. Federal, state and foundation sources are re-ingested every day, duplicate listings are collapsed onto a canonical record, and listing URLs are checked for rot — a stale catalogue is worse than a smaller current one, so dead links are flagged rather than left to look live.
