Traditionally, this was a high-growth region where energy efficiency efforts were lagging compared to some other regions and emphasis was placed on energy production. Due in large part to the efforts of sweep, the region has made great strides in advancing energy efficiency over the past 23 years. Sweep focused initially on utility energy efficiency policy and programs.programs on buildings, industrial, and transportation efficiency and electrification were subsequently added. Sweep collaborates with businesses, utilities, state and local governments, environmental and consumer groups, advocates for lower income families and disproportionately-impacted communities, and other energy experts.

The program described on its FY2025 Form 990. Program spending in total: $2,369,570.
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 2019 to 2020, from $3.2M to $2.7M (−17%).
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 22% · 2020 17%. Grants only. Government contracts and fees sit inside program revenue.
80% of SOUTHWEST ENERGY EFFICIENCY PROJECT’s revenue is contributions — about as donation-reliant as the typical peer (88% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 3 of the last 9 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
2017 → 2023: the base broadened from 4 funders to 14 funders, grant income fell $1.4M → $1.4M.
12 of 33 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 8% 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 SOUTHWEST ENERGY EFFICIENCY PROJECT’s funders (the co-funder graph). Top 30 of 33 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
SOUTHWEST ENERGY EFFICIENCY PROJECT leans on a few funders — its largest provides 38% 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
87% 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 SOUTHWEST ENERGY EFFICIENCY PROJECT.
Largest funder’s share by year: 2017 48% · 2018 61% · 2019 81% · 2020 83% · 2021 87% · 2022 76% · 2023 60% — 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.
How long its funders stay
30% of SOUTHWEST ENERGY EFFICIENCY PROJECT's funders are still giving 3 years after their first grant; 48% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
SOUTHWEST ENERGY EFFICIENCY PROJECT draws 94% of its grant income from funders outside Colorado, across 9 states in all.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $845k arriving through sponsors registered in 7 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.
