About energy efficiency grants

Energy efficiency grants fund building retrofits, weatherization, electrification, and clean-energy programs for nonprofits, local governments, and community organizations. The U.S. Department of Energy (DOE) is the primary federal funder, channeling its Weatherization Assistance Program through states, tribes, and roughly 700 local agencies, while DOE's Office of State and Community Energy Programs administers additional funding. These programs help organizations lower energy costs, improve building performance, and support clean-energy jobs.

A long list is the starting point, not the shortlist. Our grant prospecting guide shows how to narrow energy efficiency grants for nonprofits down to the funders most likely to say yes, using their giving records.

Frequently Asked Questions

How much money do energy efficiency grants for nonprofits award?

Of the 336 energy efficiency grants for nonprofits Grantable lists as of October 24, 2026, 141 publish an award amount. The median listed award is $200K, and the middle half fall between $20K and $1M. The largest is $8M. Amounts are each grant's stated maximum, so a typical award can be smaller.

Which funders offer the most energy efficiency grants for nonprofits?

By number of active listings, the leading funders are Maryland Energy Administration (26), National Arbor Day Foundation (20), The Massachusetts Clean Energy Center (MassCEC) (15), California Energy Commission (13), and New York State Energy Research and Development Authority (NYSERDA) (7). In all, 182 funders have at least one active grant in this category.

When are energy efficiency grants for nonprofits due?

Of 336 grants listed, 24 accept applications on a rolling basis, 8 have a published upcoming deadline, 44 run on a stated cycle (such as annual or quarterly) without a published date, and 260 don't publish a deadline, so check the funder's site.

What energy efficiency grants are available?

Energy efficiency grants fund weatherization, building retrofits, HVAC and insulation upgrades, electrification, and clean-energy workforce programs. The DOE Weatherization Assistance Program is the largest federal source, reducing energy costs for low-income households through local agencies, and DOE state and community energy programs offer additional funding. State energy offices and utilities also administer efficiency rebates and grants.

Who funds energy efficiency projects?

The U.S. Department of Energy is the leading federal funder, distributing formula grants to all 50 states, the District of Columbia, tribes, and U.S. territories, which then contract with community action agencies, nonprofits, and local governments. State energy offices, regional utilities, and private foundations focused on climate and housing also fund efficiency work. Eligibility depends on the program — many flow through state or local administrators rather than direct federal awards.

How do nonprofits access weatherization and retrofit funding?

Many federal energy efficiency dollars reach nonprofits indirectly: DOE awards funds to states and tribes, which then contract with local agencies to deliver weatherization services. Nonprofits should connect with their state energy office or local community action agency to learn about sub-grant opportunities and income-eligibility rules. Some competitive DOE and foundation programs also fund nonprofit-led building retrofits and clean-energy initiatives directly.
