A growing number of farms around the country are using technology to turn organic
waste into energy. But the operator of one such system says it will be difficult to expand
unless the process becomes more profitable. Michael Leland has more:
A a 20-foot-tall tank turns manure into gas that’s used to make electricity. Richard
Pieper with Clear Horizons says this Wisconsin farm can power 200 homes.
He says he’d like to expand, but it doesn’t make economic sense. It costs 20 cents to
produce each kilowatt of power, but the local utility only pays 5 cents. Solar generators are getting 22 cents a kilowatt:
“The rates have to be the rates that others at a minimum are getting for their technology.
Give us those rates, and depending on where that is, depends on how fast we can move
forward.”
Solar generators get more per kilowatt because they’re part of a program that’s funded by
customers who agree to pay more for green energy. Biogas is not part of that program.

U.S. demand for clean energy is growing fast. In fact, wind energy developers are ordering so many windmills, they’re running into a supply problem. Windmill manufacturers overseas have been shipping their products to the booming U.S. market. That’s already created some jobs, and now there are plans to build factories to produce windmills here. It’s all happening in spite of inconsistent federal support. Stephanie Hemphill reports:
At the Duluth Port Terminal, the BBC India is tied up to the dock. Two giant cranes slowly lower a silvery propeller onto a waiting truck. The blade is half as long as a football field. The extended bed of the eighteen-wheeler isn’t long enough to hold the entire length. A padded steel structure cradles the narrow end above the ground. There are 66 blades on the ship, three blades for each of twenty-two towers.
“The three blades will bolt into a hub, and then the hub attaches to the nacelle, the generator package, that’s the actual turbine, and the nacelle sits on top of the tower.”
Andrew Holdrup is the port captain for the shipping company. He was here in Duluth a year and a half ago, when the port handled its first ever shipment of windmills.
Holdrup says the demand for windmills is huge in the U.S.
“We have four ships; all they do is run from Denmark to Houston with Siemens windmills. We discharge them in Houston, the ship sails back empty to go pick up the next lot. Multiply that by all the other ports, and all the other windmill manufacturers, and it’s a huge business.”
It’s great business for Duluth’s port. Unloading the windmills requires iron workers to cut the steel where the pieces have been welded to the ship, and crane operators, and longshoremen. And truckers are staying in town waiting to pick up their loads. They’ll haul the windmills to wind farms being built in Mower County, Minnesota, and Oliver County, North Dakota. The port has also handled equipment for wind farms in Manitoba.
The boom in wind was primed in the early 1990s, when Congress set up a production tax credit for wind power. It allows a 1.9 cent-per-kilowatt-hour tax credit over ten years, for electricity produced by wind.
But the tax credit only runs for two years at a time. Ron Johnson is in charge of marketing for the Duluth Port Authority. He says that on-again, off-again approach has made it hard for businesses involved in wind energy to plan and grow.
“It’s kind of start up again, stop, start up again, stop. If you’re a trucking company with these specialized trailers, you don’t want to go out and buy fifty more of them if there’s a chance your whole fleet’s going to sit until Congress decides what to do.”
Johnson says there’s a lot of support in Congress for the tax credits, and he expects them to be renewed.
Steve Stengel works for FPL Energy, the company building the wind farms where these windmills are headed.
“It is part of the business, we understand that. And it does cause kind of starts & stops, if you will.”
But he says it’s possible to work around the periodic breaks in the tax credit because it takes a long time to plan a wind project anyway.
“Permitting issues, land lease issues, transmission issues. We have to plan as if the tax credit is going to be there.”
In fact, wind is growing dramatically in spite of the iffy nature of federal support. Several states now require utilities to invest in renewable energy, or offer incentives for wind power development. And as the cost of fossil fuels goes up, the relative cost of wind goes down.
It all adds up to a lot of demand, and recently, tight supplies.
The American Wind Energy Association’s Susan Sloan says orders are already in place for 2008 and beyond.
“Because of this boom and bust cycle but also because of this new acceptance of wind, we are seeing a tighter supply, and we need to have the manufacturing capabilities catch up.”
And that’s what’s happening.
It took two weeks for the Siemens windmills to sail from Denmark to Duluth. Now the company is building a factory in Fort Madison, Iowa. Siemens says it will employ 250 people, and start producing in the first half of 2007.
And in Pipestone, Minnesota, Suzlon, a company based in India, is about to start producing three blades a day, and the nosecones to go with them. The company plans to manufacture the electronic controls, and eventually employ up to 300 people. Suzlon says it has orders for the next two to three years.

US demand for clean energy is growing so fast, supplies of generating systems are getting tight. Stephanie Hemphill reports on a challenge that could lead to more jobs in the US:
Overseas manufacturers of wind generating systems are shipping them here as fast as they can. Now, several companies are building wind generator factories in the US.
Siemens is building a plant in Iowa. Suzlon is about to start production in Minnesota. Plants in Texas produce blades and towers.
It’s all happening in spite of inconsistent federal support. A production tax credit is in place, but it expires every two years.
Ron Johnson is with the port of Duluth, which handles windmill imports. He says the on-again, off-again support makes it hard for companies to plan and grow.
“Well, the deadline’s coming at the end of next year, and people are planning their projects, so we’re all anxious to see what Congress does.”
The American Wind Energy Association says producers are installing enough wind power this year to power the entire state of Rhode Island.
For the Environment Report, I’m Stephanie Hemphill.
While the tower is around 3 miles north of Cleveland's shore, a viable wind farm would need to be at least 6 times farther out in Lake Erie. The wind monitoring tower measures the speed, direction, and height of Lake Erie's wind to determine if wind power generation on the lake is economically viable.

Proposals for offshore wind farms, from the coasts of Texas to New England have the potential to generate more electricity than land turbines do. Lisa Ann Pinkerton reports these projects face various hurdles to becoming reality but they’re not completely insurmountable:
Over the past few months, whenever the weather is favorable, Aaron Godwin of Green Energy Ohio rides a power boat several miles out into Lake Erie. Out on the on the city of Cleveland’s century old water intake structure he’s built a tall wind monitoring tower.
“The upper part of the tower is about 168 feet above the water, so we’re measuring at about 30, 40 and 50 meters, and dual instrumentation at each level, anemometers that measure wind speed and vanes that measure direction.”
Godwin’s got almost a year of wind data and today he’s installing a small wind turbine to confirm what he’s discovered: that the lake’s wind is roughly twice as strong as wind on land. So to Godwin offshore wind farms are inevitable, especially since 75 percent of the nation’s energy use is near coastal cities.
However, proposed projects everywhere face a number of hurdles. One of them is bird and bat migration. Some land turbines have killed creatures that flew too close. But in Denmark, where offshore wind is 15 years old, extensive water foul surveys show little change in bird behavior. Charlotte Boesen is an environmental planner for Dong Energy in Denmark.
“These birds, they do fly around the wind farm. They do not like flying over land you can say and maybe they in some sort they perceive the turbines or wind farm as a similar object.”
Even so, no wind project in the US will ever get off the ground without a full assessment of potential wildlife impacts. That’s why 60% of Lake Erie has already been ruled out by a preliminary study conducted by the wind consulting firm AWS True Wind. Its Executive Director Bruce Bailey says that leaves most of eastern Lake Erie still available, with the best wind about 15 miles northwest of Cleveland.
“That’s where the strongest winds would be found. With water depths still being under say 70 feet.”
Bailey adds the shallow depth of Lake Erie combined with its solid lake bottom and fresh water makes it more friendly to offshore wind generation than oceans.
“You wouldn’t have to deal with the corrosion or the extra cost to safeguard your hardware from corrosion if you’re sighted in a fresh water lake.”
Bailey adds designing against hurricanes makes ocean projects more expensive. On the flip side, Lake Erie’s been known to freeze.
“There are ways to deflect the ice from actually pushing too strongly against or lifting out a turbine foundation. Some of them have already been deployed already in offshore projects in Northern Europe, and some of them are located in locations where you might even get icebergs.”
Another concern is whether these turbines will ruin the natural beauty of America’s Coastlines, even though on the horizon a turbine might only look a big as a thumbnail. Walt Musel of the US Department of Energy says this worry is unfounded.
“It’s worth noting there are no projects in the United States, so most people who object to offshore wind have never seen one.”
Fifteen years ago, projects in Denmark faced the same prejudice. Today tourists rent boats to go see them.
Above all, perhaps the largest impediment to offshore wind power is its high cost. Installation in water is expected to be double the cost of on land construction. However, once farms are producing power, electricity companies are open to buying it.
Out on Lake Erie, Aaron Godwin is packing up his tools for the day. He says there is an up side to those high capital costs. He says in the future, turbines will be so large it’ll make more sense to manufacture the parts locally, giving America’s manufacturing industry a ray of hope.
“Energy is a guaranteed growth market. Wind power is the fastest growing energy sector in the entire world. Why would you not want to get involved in that guaranteed growth market? It just does not make sense.”
Godwin says if the US can clear these hurdles of public perception, engineering, and environmental impacts, he thinks the US economy might find a pleasant surprise: consistent, green energy, built and harnessed off the blue coasts of America.

A growing number of institutions and governments are turning to renewable
energy for their electricity. The GLRC’s Brad Linder reports:
According to the EPA, the U.S. Air Force is the top buyer of renewable
energy in the country, with over a million megawatts of electricity
coming from wind, solar, hydro, and geothermal sources. Whole Foods Market, Johnson
& Johnson, and Starbucks also rank high on the
list.
The state government of Pennsylvania recently announced it would
double its purchase of wind and hydroelectric energy. State Environmental Secretary
Kathleen McGinty says the program will cost the state about half a million dollars. That’s
less than one percent of its total electric bill.
“So instead of us sending literally 30 billion dollars out of the state that Pennsylvanians
currently do to buy energy resources from abroad, we are investing in our own energy
resources here at home.
The doubling of its purchase makes Pennsylvania the biggest buyer of green energy
among state governments.

Many public power companies across the country have begun so-called “green power” programs.

Many public power companies across the country have begun so-called “green power” programs.
They offer customers energy produced from something other than coal, such as wind or water, if
customers agree to pay higher rates. But as the Great Lakes Radio Consortium’s Erin Toner
reports, many utilities are having a tough time getting people interested in green power:
There are two-thousand public power utilities in the United States. They’re run by local
governments, and are essentially owned by their customers – instead of by investors. A handful of
public utilities have begun offering special “green power” programs. And some of them are working
quite well.
In Minnesota, Moorhead Public Service built a second wind turbine because its “Capture the Wind”
program has been so successful. But that’s not been the case for many municipal-owned utilities.
(power plant sound up/under)
The Board of Water and Light in Lansing, Michigan, is the largest public utility in the Great Lakes
region. It began buying green power two years ago – half of it is made from landfill gas, the rest is
hydro power produced at dams in northeast Michigan. Customers can get half their power from
those sources for an extra seven-dollars-and-fifty-cents a month.
But the program hasn’t been as popular as the utility had hoped. Spokesperson John Strickler says
only 700 of the company’s 100-thousand customers have signed up for it.
“We were a little bit surprised and a little bit disappointed that we didn’t have more
customers subscribe to that product.”
It’s a problem many power companies are having. Joe Nipper is with the American Public Power
Association. He says for one reason or another, people just don’t seem to be willing to pay more
for cleaner energy.
“For many folks the power bill is a significant part of their bills every month and they watch
that closely. I think maybe another part of it is despite the effort by Lansing and others to
make the public aware of the benefits of these programs, still, in all, in some cases, little is
understood about them.”
Some environmentalists say power companies need to tell people that burning coal in power plants
pollutes the air they breathe. And that green power doesn’t release harmful emissions. David Gard
is with the Michigan Environmental Council.
“People don’t understand generally that there is a very close connection between smog and
soot pollution that come mainly from power plants and very severe health impacts that we
end up paying for as a society in very major ways. We have lots of evidence that the kinds
of pollutants that come out of coal-fired power plants are causing childhood asthma,
mercury poisoning of fish, which are then eaten by people, and other kinds of diseases.”
Gard commends the Lansing Board of Water and Light for attempting to sell cleaner energy, but he
argues the green power program will never be successful the way it’s set up now. Gard says
instead of a voluntary program, all customers should share the cost of green power.
But the Board of Water and Light’s Nick Burwell says the utility won’t raise rates unilaterally for a
service people are not demanding.
“We basically have a dual role. One in providing electricity and the other in protecting our
owners and working for our owners. And basically whatever they want is what we will
provide. If out of the blue they were to suddenly say we want you to spend this much money
and become, oh I don’t know, some new technology and triple our bills, that would be great
with us because they own us. They drive what we do and the actions we take.”
And so far, rate payers have shown they’re not that interested in buying green power. Lansing
Board of Water and Light officials say they take their responsibility to the environment and to the
health of their customers very seriously. But they say unless more people become willing to pay for
cleaner energy, they likely won’t expand the program any further.

For many people, the meaning of spirituality comes from revering a higher
power. But in northern Ohio, there’s a group of nuns working to make
spirituality a little more grounded. The Great Lakes Radio Consortium’s
Renita Jablonski introduces us to the woman who helped start it all:
Sister Mary Shrader drives to work every day in a Honda Civic. It runs
on natural gas. When she pulls into the campus of the Sisters of St.
Joseph, she parks right in front of two compressed natural gas fueling pumps. With a flip of her gray hair, she gets ready to refuel.
“This is very easy and it’s very convenient to come in to work, plug your car in, and when you come out, it’s all filled. (sound of plug being put into car) In a few seconds, the compressor will kick in.”
(sound of compressor)
The Sisters of St. Joseph have 12 CNG cars so far. They’re members of the Northeast Ohio Clean Fuels Coalition. The addition of alternative fuel vehicles to their fleet was one of Shrader’s first projects when she was elected to
the congregation’s leadership council five years ago. That’s when the sisters
first adopted a resolution to pursue unity with the earth.
Shrader entered the convent when she was 17. It was 1960. She says back then, the congregation’s teachings often considered the natural world separate from the spiritual world.
“But they are, they’re totally integrated and the respect that you get from
your spirituality flows into the earth entities and Earth gives us the awe and the inspiration.”
Before coming to the Cleveland diocese, Shrader worked in Alaska in the Diocese
of Fairbanks. It’s when she first started to realize that environmental work was
her true calling.
“I’ve always wanted to live in the country, I’ve always wanted to be with animals and well, I got there and it was not exactly as I had envisioned it because much of the
economy of the state is run on oil business and on military and on tourism.”
Before she knew it, Shrader found herself joining an environmental group,
doing work opposing oil drilling in the Arctic National Wildlife Refuge. As an
English teacher, she made it a point to teach Thoreau’s Walden to get her students to think about their relationship with nature. And now, she’s leading her sisters in Cleveland on a very green path. Shrader’s latest project is a wind power study.
Last week, Green Energy Ohio installed a 130-foot wind energy-monitoring tower on the congregation grounds.
“We have done an energy audit so that we can lower the amount of energy that we use, and use it more efficiently.
They’ve also met with a consultant to evaluate every product used on site to make sure everything’s earth-friendly. Shrader is trying to integrate this environmental ethic into the sisters’ daily lives.
“I would hope we would be able to complete the educational program that we’ve
begun for residents and staff here so that they understand that this is a part of everything we do here. So no matter what area they work in, the kitchen,
maintenance, secretarial staff, health care, the priority of earth-friendly
should be a part of the decision making, the choices, and the actions that are here.”
Shrader is working with other community and religious organizations to promote
environmental awareness. The sisters are also busy reshaping their campus to become a nature trail system with special wildlife areas.
(sound of birds)
They’ve already applied to be an official bird sanctuary.

Three U.S. Environmental Protection Agency Research Facilities in Cincinnati will start using green energy power this October. The Bush Administration recently urged government offices to be the first to conserve power. The EPA began changing power sources two years ago. The Great Lakes Radio Consortium’s Natalie Walston has details.
A mix of wind and landfill gas energies will power the southern Ohio facilities.
The EPA has contracted with companies in Pennsylvania and Illinois to provide energy. EPA spokesman Chris Paulitz says green energy costs six percent more than conventional power. Bus he says it’s a chance for the agency to “practice what it preaches.” The EPA began changing energy sources at some of its buildings in 1999. Paulitz says that when its Richmond, California Plant started using power generated by methane gas. By early next year, U.S EPA plans to have facilities in Ohio, California, Massachusetts, Colorado, and Washington State powered solely by green energy. For the Great Lakes Radio Consortium, I’m Natalie Walston.
