Over the past decade, there have been numerous studies conducted by accredited research facilities and government agencies concerning property values and wind turbines. These studies concluded that statistical evidence does not support the contention that property values within the viewshed of wind developments suffer or perfom poorer than in a comparable region. Two recent publications are cited below:
In January 2014, a joint report from the Lawrence Berkeley National Laboratory and the University of Connecticut examined 122,000 home sales near wind developments between 1998 and 2012. This study found that property values dipped slightly from the time the wind development was publicly announced until the end of the construction period. Once the turbines were up and running, property values returned to previous levels. (Relationship between Wind Turbines and Residential Property Values in Massachusetts, U of CT/ US Dept. of Energy, 2014).
In August 2013, the Lawrence Berkeley National Laboratory produced a report that expanded upon their 2009 study of the relationship between property values and turbines. Compared to earlier studies, this project represents a relatively large sample size (over 50,000 home sales) across a large area (9 states). The researchers did not find a statistically significant effect of wind turbines on the property values of nearby homes.
