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.

Companies Push for Forest Certification

  • Magazine publishers and other companies are thinking ahead and getting their paper from forests that have been certified. But what does this really mean? (Photo by Stanley Elliott)

Officials in the Midwest want to prove they’re not damaging their state forests. States that sell timber to paper companies are spending thousands of dollars to earn a certificate that says they’re managing the forests in a sustainable way. Paper producers are demanding that state foresters earn certification because officials want to stave off protests from consumers. The Great Lakes Radio Consortium’s Celeste Headlee reports:

Officials in the Midwest want to prove they’re not damaging their state forests. States that sell timber to paper companies are spending thousand of dollars to earn a certificate that says they’re managing the forests in a sustainable way. Paper producers are demanding that state foresters earn certification because officials want to stave off protests from consumers. The Great Lakes Radio Consortium’s Celeste Headlee reports:


It’s lunchtime and employees on break from Compuware in downtown Detroit are browisng through the magazine racks at Borders. Melody Kranz says she reads three different magazines every month. She says she is an avid recycler and an impassioned environmentalist, but never considered what kind of paper was going into her magazines.


“I don’t know why I haven’t thought about it, I just haven’t. I will now. Because I’m a gardening nut, I love to garden. So yeah, I just never really thought about it.”


But executive David Refkin is betting that Franz and others like her would think twice before picking up Time Magazine if they thought a forest was demolished to make the paper. Refkin is the Director of Sustainable Development for Time Incorporated. He says he’s noticed a strong surge in environmental awareness over the past two or three years.


“We don’t want people looking at a magazine and feeling guilty that a stream has been damaged and the fish are dying in there, or that habitats aren’t being protected because people are practicing bad forestry practices.”


Refkin says his company wants to take action now, before consumer groups decide to boycott its magazines over ecological issues. Time uses more coated paper for its publications than any other company in the U.S. The company is asking that 80 percent of all paper products Time buys be certified by 2006.


To the average consumer, that may not seem like big news. But for paper producers and foresters, it’s earth shattering. Larry Pedersen is with the Michigan Department of Natural Resources. Pedersen says getting certified means years of work for state employees. The government has to prove to investigators that its management standards take into account issues such as biodiversity, water quality, soil erosion and wildlife habitat. Pedersen says the state is also required to provide records for each tree from the moments it’s planted or inventoried to the time it’s cut down and then made into planks or paper. But he says it’s worth the effort.


“A number of wood and paper-using companies brought it to our attention that they needed to have certified products because their consumers were demanding those. And with us having four-million acres of state forestlands, we saw the writing on the wall that we needed to jump on this.”


State forests in the region generate a lot of revenue. Wisconsin’s forests earn two and a half million dollars from timber sales and Ohio pulls in almost three million. Michigan’s forests bring in 30 million dollars annually. Earlier this year, Michigan’s Governor Jennifer Granholm announced that all state forests will be certified by January 1st of 2006. And the Great Lakes State is not alone… New York, Wisconsin, and Maine are also pursuing certification and Ohio and other states are considering it.


Andrew Shalit, with the environmental activist group Ecopledge, says he’s glad Time Warner is encouraging paper companies and state governments to get certified. But he says that doesn’t necessarily mean the paper is produced in an environmentally friendly way.


“It’s great to say that they’re going to get all of their paper from certified forests. The question is, who is certifying? And in the case of Time Warner, a lot of the forests are certified by a group called SFI, the Sustainable Forestry Initiative, and their standards are so weak as to be almost meaningless.”


There’s a heated debate over just what certification means. There are currently two groups that certify forests in the U.S. The Sustainable Forestry Initiative, or SFI, was originally founded by the timber industry but is now an independent body. The Forest Stewardship council, or FSC, came out of the environmental movement… or more specifically, out of the effort to protect South American rainforests. Shalit says he doesn’t think SFI certification is as rigorous or as comprehensive as FSC.


“It really is a problem for the consumer because you see something in the store and it has a little green label on it with a picture of a tree and it says sustainably certified, and you think you’re buying something good. It’s hard for the individual consumer to keep up with that.”


Shalit says several states, like Michigan, have solved the dilemma of rival certification programs by getting dual certification. he says although the system has flaws, it will improve if consumers demand more stringent forestry regulations.


Executives at Time Warner hope they can avoid boycotts and pickets by taking action preemptively. The company is leading the push for forest certification in the U.S., and environmentalists say the federal government may have to bow to pressure eventually and get the national forests certified as well.
