The Energy Futures Finance Forum (EF3) is a novel effort to identify policies and measures to expand the attractiveness of investment opportunities in clean energy to a broader cross-section of the investment community. The foundation issued several reports on this topic, including a framework report identifying potential additional sources of clean energy finance and a report on identifying opportunities to enhance investment opportunities in industrial carbon capture and storage. In 2024, the Foundation launched a new multi-year effort, the Nuclear Scaling Initiative, together with the Clean Air Task Force and the Nuclear Threat Initiative, to enable the expanded deployment of new nuclear energy generation. The foundation formed the Hydrogen Demand Initiative (H2DI), a consortium of six entities, to develop a novel program design to stimulate creation of new markets for clean hydrogen.

The organization over time
Each line starts at 100 in 2022, so what you read is the shape rather than the size: 150 means half as much again as 2022, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $2.7M to $5.2M (+91%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
21% of EFI FOUNDATION’s revenue is contributions — more earned-revenue than three-quarters of its peers (87% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 1 of the last 3 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2022 → 2023: the base broadened from 2 funders to 5 funders, grant income fell $2.2M → $1.5M.
3 of 12 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 9% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of EFI FOUNDATION’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
EFI FOUNDATION leans on a few funders — its largest provides 43% of grant income and the top three 74%; half comes from just 2 funders.
the vertical line marks half of all grant income — 2 funders to its left
79% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund EFI FOUNDATION.
Largest funder’s share by year: 2022 93% · 2023 48% — diversifying over time.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Where its funders are
EFI FOUNDATION draws 100% of its grant income from funders outside Washington, D.C., across 7 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $575k arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
