Share of utility-scale installed capacity, by source
This interactive map and sortable table show every utility-scale wind farm in the United States, all 1,554 wind farms of 1 MW or larger in the U.S. Energy Information Administration’s EIA-860 (2025 early release). Each entry is a wind farm (an EIA plant), not an individual turbine, color-coded by type: onshore (1,541) and offshore (13). Wind is the largest source of US renewable electricity after hydropower, at roughly 166 GW of active and standby capacity here, concentrated across Texas and the Great Plains. Farms are shown across all statuses: active (1,373), standby (10), in development (74) and decommissioned (97), including the four offshore farms EIA lists as operating, gigawatt-scale offshore projects still under construction, and a few cancelled ones. Together, the 1,373 active wind farms mapped here have a combined capacity of about 165,600 MW (~166 GW). Source: U.S. EIA Form EIA-860 (2025 early release), Schedules 2 (Plant) and 3 (Generator), with every plant’s status and capacity then reviewed against the Preliminary Monthly Electric Generator Inventory (EIA-860M), June 2026.
Capacity is what is installed; generation is what actually ran. Wind holds 12.52% of US utility-scale generating capacity and produced 10.47% of the electricity in 2025, an implied capacity factor of 32.0% on a nameplate basis. Nuclear is the extreme case in one direction, at 7.32% of capacity for 17.70% of generation; solar is the extreme in the other, at 12.50% for 6.67%.
Sources, basis and how the totals reconcile
Sources. Generation is EIA Electric Power Monthly, Table 1.1, Net Generation by Energy Source: Total (All Sectors), annual 2025 row. EIA marks 2025 and 2026 values as preliminary; 2024 and earlier are final, so these shares may be revised. Capacity is this site’s own datasets from EIA-860 (2025 early release), reconciled against EIA-860M (June 2026).
Basis. Both charts cover utility-scale plants of 1 MW or larger, generating sources only. Battery storage is excluded from the capacity chart because it shifts power rather than producing it, and estimated small-scale rooftop solar (93,148 GWh in 2025) is excluded from the generation chart so the two stay comparable.
Totals. The generation slices sum to 4,434,820 GWh. EIA’s published net total is 4,429,502 GWh, being that figure less 5,320 GWh of net pumped-storage hydro, which EIA reports as a negative because pumping consumes more electricity than generation returns, and a further 2 GWh that EIA attributes to independent rounding. Pumped storage is left out of the pie because a negative value cannot be drawn as a slice. Percentages use largest-remainder rounding at two decimal places so each chart adds to 100.00%.
Category notes. EIA reports wind, biomass and geothermal as one 526,246 GWh category; the split here carries a one-unit adjustment on wind so the three reconcile to that published total. Biomass covers wood and wood waste, black liquor, landfill gas, sludge waste, agricultural byproducts and biogenic municipal solid waste. Other fossil gas is blast furnace gas, gaseous propane and other manufactured waste gases; Other is hydrogen, non-biogenic municipal solid waste, batteries, purchased steam, sulfur and tire-derived fuel. One definitional seam is worth knowing: EIA-860 files gaseous propane under petroleum products, while Table 1.1 files it under other fossil gas, so the same fuel sits in the Petroleum slice on the capacity chart and the Other fossil gas slice on the generation chart. Only one 2.3 MW plant is affected.

EIA preliminary data
Wind output in the United States peaks overnight and in the early morning. After sunset the lower atmosphere stabilises and decouples from the surface, letting the low-level jet accelerate across the Plains, so the windiest hours are often the ones with the least demand.
Method: this is a modeled profile, not metered data. The 24-hour mean of 32.0% is the implied annual capacity factor, calculated as 2025 generation from EIA Electric Power Monthly Table 1.1 divided by the nameplate capacity of the active fleet on this page multiplied by 8,760 hours. EIA’s own published capacity factors use net summer capacity as the denominator and therefore run higher. The hourly shape applies the documented operating behaviour of this technology to that mean and is indicative rather than measured; metered hourly output would come from the EIA Hourly Electric Grid Monitor, which is not yet wired into this page.

Nearly all US wind is on land, concentrated across Texas and the Great Plains where the wind is strongest. Onshore wind is the country’s largest source of renewable electricity after hydropower, with farms ranging from a few turbines to over 1,000 MW.
A newer, fast-growing frontier off the Atlantic coast using much larger turbines in stronger, steadier sea breezes. Only a few farms operate today (Block Island, South Fork, Vineyard Wind), but several gigawatt-scale projects are in development, and a few have been cancelled.
Each row here is a wind farm (an EIA plant), not a single turbine. Capacity is the sum of all the farm’s turbines. This is the utility-scale fleet (1 MW and larger) tracked by EIA, not the hundreds of thousands of individual turbines.
Any utility-scale wind plant (1 MW or larger) in EIA-860 (2025 early release) whose energy source is wind (code WND), aggregated to the EIA plant, meaning the wind farm rather than each turbine. That yields 1,554 farms. Type is set by prime mover: an onshore turbine (WT) or an offshore turbine (WS).
Farms. A single wind farm can contain dozens or hundreds of turbines; here each row is the whole farm, and its capacity is the sum of all its turbines’ nameplate ratings. Individual turbine locations are tracked separately in the USGS U.S. Wind Turbine Database.
About 166 GW of active and standby capacity, the largest source of US renewable electricity after hydropower. The vast majority is onshore (1,541 farms); offshore is small but growing (13 farms).
Offshore wind is a fast-growing frontier off the Atlantic coast. Only a few farms operate today (Block Island, South Fork, Coastal Virginia pilot, Vineyard Wind), with several gigawatt-scale projects in development. A few proposed projects (e.g. Ocean Wind, Skipjack) were cancelled and appear as decommissioned.
Yes. Dozens of farms are in development, both large onshore projects in the Plains and gigawatt-scale offshore projects on the East Coast. EIA-860 lists those proposed units here under “In development.”
It is the EIA-860 2025 early release (Schedules 2 and 3). EIA notes the early release is not fully edited and may withhold a few plants pending validation; farms below 1 MW are not part of EIA-860.
Wind has a geography as distinct as any source on the website: a great corridor running up the center of the country from Texas through Oklahoma, Kansas, Iowa and the Dakotas, where the Plains deliver strong, steady wind and cheap open land. Texas and Iowa alone account for an outsized share of the roughly 160 GW of active capacity. A scattering of farms also dots the mountain West, the Northeast and the Pacific coast.
Two frontiers define wind’s future, and both appear on the map. The first is offshore: a small but fast-growing set of Atlantic projects using far larger turbines in stronger sea breezes, with several gigawatt-scale farms in development even as a few have been cancelled. The second is repowering. This means swapping older turbines for taller, more productive machines on existing sites. Remember that each entry here is a whole wind farm, not a single turbine, so a single dot can represent hundreds of machines.
