Wind farms of huge turbines are springing up along coast lines, windy ridges and
blustery
farmland. Most of us see them from a distance. The Great Lakes Radio Consortium’s
Chris
Lehman recently visited some of them up close… and has the first of two reports on
wind energy…


If you can imagine the sight… there are 63 wind turbines scattered across the
prairie farmland,
their huge blades sweeping around, capturing energy from the wind. Each turbine is
213 feet
high. You can see them from miles around. But it isn’t until you stand directly
underneath the
80-foot long blades as they rotate in the wind that you begin to appreciate their size…

“This is probably a typical day. They’re probably producing at about 30 percent of
what they are
rated at, and probably on average, for a year, this is what you’d expect.”


Christopher Moore is Director of Development for Navitas Energy. The Minnesota- based
company opened the Mendota Hills Wind Farm in northern Illinois just over a year ago.


Q: “What are some of the highest levels that you’ve reached?”


“Each turbine is capable of producing 800 kw, and there are times when we’ve had the
windfarm
working at about maximum.”


Moore says the Mendota Hills Wind Farm produces enough electricity to power about 15-
thousand homes per year. It’s the first wind farm in the state of Illinois.


Brian Lammers is a Project Manager for Navitas Energy. He says the location is
ideal since it’s
windy here nearly all year long…


“The wind here is more robust in the fall, winter and spring. So we have more
production during
those months than we do during June, July, August.”


Unfortunately, the summer months are the months that most often experience peak
demand for
electricity. Because of that, and because it takes so many windmills to generate
lower amounts of
power, it’s unlikely that current wind energy will completely replace fossil fuel
generated power.


(sound of turbines)


On the flat prairies of Illinois, the giant turbines are the tallest structures for
miles around. You
begin to wonder about things like lightning strikes…


“We might have experienced one or two last year. The turbines are protected from
lightning. The
entire wind farm is grounded, so if there is a strike typically it will just be
grounded down to the
ground grid. There’s typically no long-term damage associated with a lightning
strike. But as you
can imagine, they’re the tallest structures around so there are periodic lightning
strikes.”


Q “What about a tornado? This is tornado country…what would happen if one came
through
here?”


“I don’t know. These turbines are built to withstand everything but a direct strike
from a tornado,
so I think the same thing would happen to a wind turbine that would happen to any
large
structure if they were struck by a tornado. You’d probably have some significant
damage.”


(fade up sound inside turbine)


Inside the turbine, there’s a distinct hum as the blades whirl away at the top of
the hollow shaft.
It’s about ten feet across at the base, and a metal ladder allows anyone brave
enough to climb all
the way to the top.


Despite the hum of the turbine’s blades up close, the sound fades away just a few
dozen feet from
the tower. But noise isn’t much of a concern for this wind farm. It’s in the
middle of a soybean
field and there are no neighbors nearby.


Noise is just one of the aesthetic concerns for neighbors of wind farms. Appearance
is another.
The Mendota Hills turbines are coated with a special paint that appears white in
bright sunshine.
But when the sun’s not out, the turbines appear grey, and seem to blend in with the
cloud-covered
sky.


Dennis Cradduck has 19 of the turbines on his corn and soybean farm. He says the
wind farm
hasn’t been a problem. Of course, he’s getting paid by Navitas for allowing the
turbines on his
land. But he says the wind farm has led to an unexpected benefit: getting to meet
people from
across the country who pull off the highway for a closer look…


“We get people almost on a daily basis that drive by on the interstate and see them,
and stop and
want to look at them, and they’re amazed at them, and most—about 99 percent of them
have been
positive comments. In fact, one fellow from North Carolina stopped the other day
and said ‘I wish
we’d build more of these around the country because we need renewable energy.'”


The prospect of more renewable energy is appealing to most environmentalists. But
some worry
that wind farms can be deadly to birds. A study by the National Wind Coordinating
Committee
found that wind turbines kill an average of two birds per year.


Another concern is that windmills disrupt the scenery. But the only view around
here is farmland
as far as the eye can see. And on this brisk day, it isn’t just corn and soybeans
being harvested: it’s
the power of wind.

Wind Turbines Stir Up Neighbors (Part 2)

Most people think renewable energy is a good idea. It’s better
than burning fossil fuel to create electricity. But “green energy”
alternatives
can be controversial. Windmill farms are springing up all across the
nation.
Some people think the windmills are eyesores. But others say windmill farms
can help preserve the agricultural landscape by supplementing the income of
farmers. In the second of a two-part series on wind energy, the Great Lakes
Radio Consortium’s Linda Stephan reports:

Most people think renewable energy is a good idea. It’s better than burning fossil
fuel to create
electricity. But “green energy” alternatives can be controversial. Windmill farms
are springing
up all across the nation. Some people think the windmills are eyesores. But others
say windmill
farms can help preserve the agricultural landscape by supplementing the income of
farmers.
The Great Lakes Radio Consortium’s Linda Stephan reports:


For 30 years, Matt Mauer raised crops and livestock on his farm about 10 miles from
the Lake
Michigan shoreline. Today, he’s in his backyard looking at the land now farmed by
his daughter
and son-in-law. Standing there, he feels a crop they’re not harvesting.


“The good Lord makes it windy all the time for us, so let’s use it, you know.
Because I’m like
everybody else. When I get up in the morning, I want lights.”


Mauer’s hoping to put four wind turbines on his family’s farm near Ludington,
Michigan. That
would power about 24-hundred homes. Nearby, a renewable energy company’s working with
other farmers to build a hundred turbines in the area. Mauer says many of his
neighbors want in
on the deal because they think wind energy could help save their farms.


“It’s hard to make a living just farming right now. And I consider the wind one of
the crops that
we could harvest. It will help keep farmers on the land. Like if, in this place, if
we could get
seven–thousand dollars a year, six-thousand dollars a year for four of them, that’d
make it a hell
of a lot easier to keep the people here and farm.”


The state government’s backing similar projects. It’s training financial advisors
to show farmers
how they can turn a profit with windmills.


But not everyone likes the idea. Some people who live in the area around the
planned windmills
say they’re worried the towers would destroy the region’s charm. That’s linked to
property values
and to tourism. And they don’t like the size of the proposed windmills. Each one
would be four-
hundred feet tall. The blades would have a diameter nearly as long as a football
field.


It’s a story that’s heard in many places. Cape Cod, Massachusetts, the prairies of
Illinois, and
around the Great Lakes. For example, a Michigan couple who wanted large-scale
turbines on
their property ended up losing a court-battle against local government that opposed
the plan. And
two turbines already in place in Mackinaw City – between Lake Michigan and Lake
Huron –
have some unhappy neighbors as well.


Thomas and Virginia Alexander’s home is about 15-hundred feet away from the windmills.
They’re in their eighties and they both wear hearing aids… but even without them,
they say the
windmills are loud…


Tom Alexander: “There’s things about it we don’t appreciate, at times the noise –
not always –
depending upon the wind and the direction.
Virginia Alexander: “Yesterday. Very noisy yesterday. The wind was high and they,
you could
really hear them.”
Tom Alexander: “Just a continual swish, swish, swish, swish, swish.”


Windmill developers say the sound is no louder than normal speech. But this noise is
different. It
goes beyond the frequencies of normal speech. The sound can travel long distances
through both
the ground and the air. They keep Virginia Alexander awake some nights.


Tom and Virginia Alexander’s son Kelly lives next door with his family. He calls
himself a
windmill victim. He has this advice for others:


“Don’t let them go in your backyard. There are places they can go. You don’t just
put those in
somebody’s backyard. I don’t think it’s right.”


A lot of people agree with the Alexanders. Even wind energy boosters concede that
location is
key to successful projects. David Johnson heads up the program for the state of
Michigan that’s
encouraging farmers to allow windmills on their land. He says turbines should be
constructed
where there’s lots of wind and few neighbors. But he says when people say ‘no’ to
windmills,
they should consider the alternative.


“So, does that mean that you should build another big coal-fired plant? Is that the
preferable way
of doing it with the global warming impacts and the mercury pollution and so on that
go with
that? Is that the choice that the public wants to make?


States across the nation are struggling to find the right balance between clean
energy and the
beauty of an uncluttered landscape. Few regulations are in place right now. More
and more,
communities will be facing the decision of whether clean energy and keeping farmers
on the land
is worth the price of adding wind turbines to the scenery.
