New Berkeley Lab Study Finds No Statistical Evidence of Residential Property Value Impacts Near U.S. Wind Power Projects

In
the study released yesterday, Berkeley
Lab analyzed more than 50,000 home sales near 67 wind
facilities in 27 counties
across nine U.S. states.  In
summary, the
research did not find any statistically identifiable impacts
of wind facilities
to nearby home property values. Read the full 2013 report, the previously published 2009 report, and yesterday’s press release below for more information.

Immediate release — Lawrence
Berkeley National Laboratory (Berkeley Lab) analyzed more than
50,000 home
sales near 67 wind facilities in 27 counties across nine U.S.
states, yet was
unable to uncover any impacts to nearby home property values.

“This
is the second of two major studies we have conducted on this
topic [the first
was published in 2009 –
see below], 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,” says Ben Hoen, the lead author of the new report.

Hoen
is a researcher in the Environmental Energy Technologies
Division of Berkeley
Lab.

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
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 measureable 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 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
non-existent.”

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
(San Diego State University)
and Peter Cappers (Berkeley Lab). The research was supported by
the U.S.
Department of Energy’s Office of Energy Efficiency and Renewable
Energy.
