A summary of national research on home sale data near utility-scale wind projects
Property value concerns are frequently raised when wind projects are proposed. In recent years, several large-scale national studies have analyzed hundreds of thousands, and in some cases millions, of U.S. home sales to measure actual market impacts tied to turbine visibility, distance and timing.
Here is what the data shows.
Distance Matters
National research finds that homes with at least one visible utility-scale wind turbine within 10 kilometers sell for about 1% less on average compared to homes without visible turbines.
Impacts are strongest closest to turbines. Within 1.5 kilometers, or roughly 1 mile, some markets show price declines of up to 8%. The effect steadily diminishes with distance and becomes statistically indistinguishable from zero beyond roughly 8 kilometers, or about 5 miles.
Visibility concentration also plays a role. Each additional 10 turbines in view are associated with about a 0.2% additional reduction in value. Properties with more than 20 turbines visible show average reductions of about 2.5%.
Time Matters
Price effects are not static. National data shows impacts tend to peak around three years after construction and generally disappear within about seven years. Research also identifies a temporary anticipatory effect following project announcements, particularly within one mile. However, those price changes recover over time and become statistically insignificant several years after operations begin.
Rural and Urban Differences
Measured impacts are concentrated primarily in urban and suburban counties, especially those with populations above 250,000. In rural counties, most national studies find no statistically significant change in residential property values tied to turbine proximity.
General Consensus
Across multiple datasets, the consistent conclusion is that property value effects, where measurable, are localized, distance-dependent and time-limited rather than uniform or permanent.
For communities and landowners evaluating siting decisions, national research provides measurable outcomes drawn from real transactions across diverse markets.
