The presence of wind turbines and wind farms near residential properties has no effect on the value of said properties, according to new research from the Lawrence Berkeley National Laboratory (Berkeley Lab). The findings are the result of an analysis of the sales of more than 50,000 homes — located near 67 different wind energy facilities, spread throughout nine different US states.
“This is the second of two major studies we have conducted on this topic [the first was published in 2009], and in both studies [using two different datasets] we find no statistical evidence that operating wind turbines have had any measureable impact on home sales prices,” states Ben Hoen, lead author of the new report, and a researcher in the Environmental Energy Technologies Division of Berkeley Lab.
The press release from the DOE/Lawrence Berkeley National Laboratory explains the research:
The new study used a number of sophisticated techniques to control for other potential impacts on home prices, including collecting data that spanned well before the wind facilities’ development was announced to after they were constructed and operating. This allowed the researchers to control for any pre-existing differences in home sales prices across their sample and any changes that occurred due to the housing bubble.
This new research — while certainly being the most comprehensive to date — simply builds upon previous work from the Berkeley Lab, as well a work from a variety of other researchers — most studies on the subject in the US gave found “no measurable impacts” on housing prices near operating wind turbines.
“Although there have been claims of significant property value impacts near operating wind turbines that regularly surface in the press or in local communities, strong evidence to support those claims has failed to materialize in all of the major U.S. studies conducted thus far,” Hoen explains. “Moreover, our findings comport with the large set of studies that have investigated other potentially similar disamenities, such as high voltage transmission lines, land fills, and noisy roads, which suggest that widespread impacts from wind turbines would be either relatively small or non-existent.”
