WINDMILLS and TURBINES

 
Just across the border from Indiana in Ohio
there is a stretch of road that houses wind turbines.
 
 
 
Approximately 200 of these modern day
windmills  dot the landscape,
with another 500 planned
for installation.
 
 
 
You do not realize the enormity of the structures
until you get close enough to them.
 
 
 
EXCERPTED FROM the
AKRON BEACON JOURNAL
and OHIO.COM
I took the following information

 
"Each turbine has about 8,000 parts, but arrive in pre-assembled units by truck and rail. The tower alone weighs 285 tons and arrives in five pieces. About 300 workers are involved in the construction. The towers rise 328 feet from the bases to the hubs where three blades, each 148 feet long, attach. With blades upright, the turbines’ height reaches 476 feet. 411-ton turbines reach to the skies to catch the best winds high above the soybean and cornfields that dominate the flatlands of western Ohio. Each one costs about $2 million and can supply enough energy to power 500 typical Ohio homes. The turbines begin generating electricity when the winds hit 8 or 9 miles per hour. Electricity production increases up to 28 miles per hour, but higher winds do not produce more power. $1.1 million a year is paid in leases to property owners, with about $8,000 to landowners where the turbines are sited, and smaller amounts to neighbors. Some neighbors have raised concerns about the health threat, noise, the loss of aesthetics, declining property values, a loss of quality of life, flicker or shadows passing over buildings, the impact on birds and bats and other issues. The noise from the turbines will be a swooshing sound of about 50 decibels. In comparison, background noise is generally 30 to 50 decibels. Working in an office is 60 to 70 decibels and riding in a car is 80 to 90 decibels. Therefore wind farms generally have had strong community support and little opposition here."
 
 
HERE ARE A COUPLE VIDEOS I SHOT
OF TWO OF THE WIND TURBINES
WE GOT CLOSE TO.
