National lab reiterates: Wind power doesn’t affect property values

“This is the second of two major studies we have conducted on this topic [the first was published in 2009 – download the 2009 LBNL Report], and in both studies [using two different datasets] we find no statistical evidence that operating wind turbines have had any measurable impact on home sales prices,” says Ben Hoen, the lead author of the new report.

Mr. Hoen is a researcher in the Environmental Energy Technologies Division of Berkeley Lab. The new study, the laboratory said in a news release, used a number of sophisticated techniques to control for other potential impacts on home prices, including collecting data that spanned a time period from well before the wind facilities’ development was announced to after they were constructed and operating. This allowed 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 study, the most comprehensive to-date, builds on both the previous Berkeley Lab study as well a number of other academic and published U.S. studies, which also generally find no measurable impacts near operating 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,” says Mr. Hoen.  “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 nonexistent.”

The report was authored by Ben Hoen (Berkeley Lab), Jason P. Brown (formerly USDA, now Federal Reserve Bank of Kansas City), Thomas Jackson (Texas A & M and Real Property Analytics), Ryan Wiser (Berkeley Lab), Mark Thayer (UC San Diego) and Peter Cappers (Berkeley Lab). The research was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy.
