The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 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 2021 to 2022, from $26M to $59M (+125%).
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.
Government-grant reliance: 2017 91% · 2018 90% · 2019 90% · 2020 92% · 2021 95% · 2022 95% · 2023 96% · 2024 96% · 2025 96%. Grants only. Government contracts and fees sit inside program revenue.

Who funds it, year by year
2019 → 2023: the base narrowed from 2 funders to 1 funder, grant income fell $7k → $186.
2 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 72% 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 GREENVILLE RENEWABLE ENERGY EDUCATION NETWORK’s funders (the co-funder graph). Top 4 of 5 funders by total. 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
GREENVILLE RENEWABLE ENERGY EDUCATION NETWORK leans on a few funders — its largest provides 57% of grant income and the top three 89%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
72% 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 GREENVILLE RENEWABLE ENERGY EDUCATION NETWORK.
Largest funder’s share by year: 2019 77% · 2020 100% · 2021 71% · 2022 100% · 2023 100% — growing more concentrated.
“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
72% of GREENVILLE RENEWABLE ENERGY EDUCATION NETWORK's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $3k that is directly attributable, 100% of it comes from funders outside South Carolina, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $6k arriving through sponsors registered in 2 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.
