This summer, drivers got a crash course in the dangers of fossil fuel. Gas prices shot above $3 a gallon, concerns about global warming surged, and instability continued to plague areas of the world where oil is produced. We’ll be taking a look at some of the technologies that could help the US kick its fossil fuel habit. We’re starting with an alternative fuel that’s been sprouting up in gas stations across the region. Dustin Dwyer has this look at the promise, and the limitations of ethanol:


This summer, Misty Childs found a way to do something positive about the fossil fuel problem. She says that she and her husband realized their Chevy Silverado pickup could run on E-85, a blend of 85 percent corn-based ethanol and 15 percent gasoline.


E85 burns cleaner than gas alone, so it’s good for the environment. And the ethanol is made from corn grown in the US. As she tops off her tank at a gas station, Childs says that makes a difference.


“It means a lot that we’re doing something for our country here, and not having to rely on others.”


Detroit’s Big Three automakers have been making a big push for E-85 in the last year. E-85-capable vehicles get the automakers a credit on federal fuel economy standards. So, even if drivers put regular gas in the vehicles instead of E-85, Detroit still gets a credit for doing better. And this summer, as more buyers became aware of the problem with fossil fuels, E-85 was just about the only alternative Detroit had to offer.


But ethanol as it’s currently made has limits. Jason Hill is a researcher at the University of Minnesota. He recently published a study on the long term outlook for corn-based ethanol.


“What we found is if you convert every corn kernel we produce in this nation to ethanol, we would be able to offset only about 12 percent of our national gasoline usage. So that’s not that large.”


That’s every corn kernel, including what we currently use for food. Which brings up another problem with ethanol: if E85 jumps in popularity, will that mean less corn for animal feed and grocery stores?


Maybe. Corn originally became popular because it was already being grown around much of the country, with help from federal subsidies. And ethanol processors, such as Archer Daniels Midland, also got tax breaks for making corn-based fuel.


But there’s another option for ethanol. Inside a lab at Michigan State University, researchers are working on the next generation of the fuel. This is what’s called cellulosic ethanol. Instead of using grains like corn kernels, cellulosic ethanol is made from the starches in plant cell walls. It can be made from pretty much anything that stands up straight – wood, prairie grasses and corn stalks.


That offers the possibility to increase the ethanol output for every acre of land devoted to the crops, and those crops don’t require fossil fuel-based fertilizer. They also don’t require planting every year by gas or diesel burning tractors the way corn does.


Professor Bruce Dale heads research into cellulosic ethanol at MSU. He says the current problem with cellulosic ethanol is finding a cheap way to break down the stiff materials. His lab uses ammonia to do the trick.


“The idea is to make cheap sugar. And the plant cell walls potentially could give you the cheapest sugar on the planet, if we could figure out how to get at that sugar easily. That’s what our ammonia process does in combination with the enzymes.”


It turns out that, much like a teenager eating pop-rocks, cars and trucks get a whole lot of energy from fuels based on sugar. Dale says most woody plants have plenty of sugar, but it’s really hard to get that sugar out.


Dale says some cellulosic ethanol could be on the market in the next few years, and the fuel could eventually sell for about 60 cents a gallon.


Right now, ethanol is still hard to find at the pumps. And one study says, even with major investment over the next decade, cellulosic ethanol might only equal half of our current oil useage by 2050.


That’s still a lot. But to really eliminate the need for gas, many experts say it’ll take more than just one technology.

Ten Threats: Coaster Brook Trout

A lot of native fish have been hurt by pollution, invasive species and changes we’ve
made on the lake, but one fish stands out. For anglers, the Coaster Brook trout might have
been the greatest Great Lakes fish. It was abundant, fun to catch and lived in the cleanest
water, but throughout the 20th century, its populations declined just as the health of the
lakes did. Now, slowly, a diverse group of people is trying to save the fish in an effort

We’re continuing our look at Ten Threats to the Great Lakes. Lester Graham is the
series guide. He says one of the threats is a disappearing species.


A lot of native fish have been hurt by pollution, invasive species and changes we’ve
made on the lake, but one fish stands out. For anglers, the coaster brook trout might have
been the greatest Great Lakes fish. It was abundant, fun to catch and lived in the cleanest
water, but throughout the 20th century, its populations declined just as the health of the
lakes did. Now, slowly, a diverse group of people is trying to save the fish in an effort
that could improve the Great Lakes too. The Great Lakes Radio Consortium’s Chris
McCarus reports:


(Sound of river waterfall)


Hundreds of feet above Lake Superior, the Salmon Trout River flows fast and falls hard
onto a rocky bottom below. Much of the river lies within a large tract of private woods
and hills. It’s been untouched for about a century.


Peter Dykema and his family are part owners of the land. He speaks with affection about
fishing for coaster brook trout here as a kid.


“Well as you can tell it’s a beautiful river and there’s nothing a 14 year old boy would
rather do than get his feet cold and wet and throw flies into trees. So, I did it every
chance I had.”


Dykema is nostalgic because those days are long gone for almost everybody. He’s part
of a group of activists trying to restore the coaster brook population.


Coaster brook trout have sparkling colors. They’re even more colorful than Rainbow
trout, and they grow a lot bigger. They can reach 2 feet and 4 pounds. These indigenous
fish used to live in 200 streams around Lake Superior. People came from all around the
nation to fish for them. Presidents Roosevelt and McKinley came to Michigan to catch
them, and they were caught by the boatload.


Over fishing was one of the biggest reasons why they were nearly wiped out. Their
habitat was damaged from mining and road building. Silt filled in the rock bottom where
they like to lay their eggs. That also hurt the fish.


Logging damaged the coaster brook’s habitat. Scott Libants is a fish and wildlife
researcher at Michigan State University. He says loggers dammed up streams to flood
them. Then they packed them with logs. When they had enough, they broke the streams
back open so the logs would float down to the lake to be sold.


“You knock the dam out and send all the trees down. You scour the watershed. It’s like
flushing a toilet.”


The fish haven’t recovered since. They just couldn’t take the abuse.


The Salmon Trout River still has them because the private landowners banned fishing
and didn’t alter the land. It’s one of only a handful of streams in the U.S. and Canada
that still has the coaster brook trout.


(Sound of people walking in the woods)


Downstream on the way to Lake Superior, Peter Dykema and state environmental
officials walk to the spot where they have equipment that counts the numbers of coaster
brooks going up river to lay their eggs. Dykema says they counted more than 80 fish last
season. The population seems to be slowly increasing here, but the stream still isn’t
perfect. There’s too much sand and not enough gravel for laying eggs.


“Most of the sediment problem we are looking at is a creature of the last 40 or 50 years.
So if we can stop the input, I’m hoping that the river will be able to cleanse itself.


The sediment Dykema is talking about comes from the points where roads cross the river.
People and cars jar soil loose and it fills up the riverbed. This is the fish’s current
challenge. Coaster brook trout are sensitive and susceptible to pollution. Conservation
officials use brook trout as indicators of high water quality. Coaster brooks will die if
they don’t have nearly perfect conditions.


(Sound of Lake superior waves lapping on rocks.)


Few anglers alive today have seen coaster brook trout, but if they could this would be the
place. It’s where the Salmon Trout River meets Lake Superior. For a diverse group of
conservationists, this place symbolizes what people did to the land and water of the
region.


Laura Hewitt is visiting from Trout Unlimited in Wisconsin.


“This is a fish that presidents came to fish for, that Hemingway wrote about. It’s
something that captures the imagination, it touches the soul. It’s a fish that we care
very much about and think it can be sort of a rallying point for action in the basin.”


Those working to preserve the last few hundred coaster brook trout say we should feel
lucky that they’re not all gone. They say now’s the time to keep what’s left, build it up,
and use the eggs from this small population to start the fish in other streams of Lake
Superior. Then perhaps within our lifetime, our children can enjoy the fish that our great
grandfathers did, and in doing that, they’ll know the water’s clean.

Tighter Regs on Future Ge Foods?

A recent study from a group of scientists suggests the government should keep a closer eye on genetically modified foods. The Great Lakes Radio Consortium’s Tom Weber reports:

A recent study from a group of scientists suggests the government
should keep a closer eye on genetically modified foods. The Great
Lakes Radio Consortium’s Tom Weber reports:


The study is from the National Academy of Sciences. Authors found
there’s nothing inherently hazardous about the way foods are
genetically altered today.


Tim Zacharewski is with Michigan State University. He’s one of the
scientists who helped write the report. He says the report is a
response to points raised in the ongoing debate over genetically
modified foods…


“There’s growing concern within the consumer market, as well as with
trading partners, that these products may actually not be safe. At
this time there’s no evidence to support that.”


But Zacherewski says the study also notes there is a potential that
future products could be unsafe… especially as newer technology
allows more and more types of food to be altered. And the study’s
authors say that the government should focus its regulations on those
newer technologies.

Scientists say they’ve found a fungus that kills the Emerald Ash Borer. The tiny green
beetles have devastated ash tree populations in parts of Michigan, Ohio, and Canada. Now the Emerald Ash Borer is moving farther west. The Great Lakes Radio Consortium’s Erin Toner has more:


Researchers with the U.S. Forest
Service and Michigan State University
say a product called “BotaniGard”
kills the Emerald
Ash Borer in lab tests. But they say
it isn’t clear yet whether the product
is effective against widespread
infestation.


BotaniGard is produced
by Emerald BioAgriculture
Corporation. Company President
John McIntyre says
it’s safe for people and animals.


“That’s one of the nice things about
biological pesticides. They oftentimes
are, and in the case of
BotaniGard, certainly is something
that is not harmful to the environment
or to the user.”


BotaniGard is not a new product.
Farmers have been using it since the
late 1990’s. The company plans
to donate some of the product to local
governments dealing with
Emerald Ash
Borer infestation.

People who suspect they’re sick because of something they ate can go to a new Web site to find
out if others are having similar symptoms. The Great Lakes Radio Consortium’s Erin Toner has
more:


The Web site was created at Michigan State University’s National Food Safety and Toxicology
Center. It started as a pilot project in three mid-Michigan counties. But now it’s being expanded
because people from all over the country are logging on. Holly Wethington manages the project.


“If they became sick and they thought that they had eaten something that was bad or maybe
something didn’t taste right, and then they started to experience either vomiting or diarrhea, they
would log on to the Web site and report their symptoms and food that they had eaten, to see if
others had reported those too.”


Wethington says state and local health agencies check the site regularly. The Centers for Disease
Control and Prevention say about 5000 people die of food poisoning every year in the U.S. The
Web site is the letters R-U-sick and the number two, RUsick2.msu.edu.

Campus Power Plants Struggle to Keep Up

For universities across the Midwest energy costs are becoming a huge expense. Schools are increasingly reliant on technology and many are adding new research facilities. With that growth has come an increased demand for electricity, and at a number of schools around the region, aging power plants can’t keep up with that demand.

For universities across the Midwest, energy costs are becoming a huge expense. Schools are increasingly reliant on technology and many are adding new research facilities. With that growth, has come an increased demand for electricity. And at a number of schools around the region, aging power plants can’t keep up with that demand. The Great Lakes Radio Consortium’s Erin Toner reports on this growing problem:

Jeff Bazzi is a freshman at Michigan State University. He shares a dorm room on campus with three other students. They use a lot of electricity.

(Natural sound up/under — computer, fan, radio, TV)

In this one dorm room, there are four computers, two stereos, two televisions, three refrigerators, three fans, one microwave and four alarm clocks. Jeff Bazzi says even though he doesn’t get an electricity bill from the university every month, he’s aware of the amount of energy he uses.

“I know if I was at home my mom would yell at me for wasting electricity, running her bill up. So I still try to conserve. I don’t leave lights on around me and leave the TV on and all that, I try to conserve.”

And
that’s exactly what the university wants Bazzi and other students, faculty and staff to do…conserve. Last year, Michigan State launched an energy conservation campaign to promote ways to reduce electricity consumption. University officials say small changes on everyone’s part, such as turning off lights and computers, can collectively result in lower energy costs. Terry Link is the director of MSU’s Office of Campus Sustainability. He says just a five-percent reduction in electricity demand could save the university one million dollars a year.

“What we need to do is create that environment so that people become more aware that what they’re doing has an effect, it has a cost. It’s not immediate to their wallet, but it has other kinds of costs. And then to give them tools, examples, of how, if they feel they should do something to reduce that, what they can do.”

University officials say energy conservation is especially important now, as MSU struggles with a much tighter budget this year. Also, saving energy could delay a much larger problem. In the not-too-distant future, Michigan State’s power will no longer be able to provide enough electricity for campus. Bob Ellerhorst is the power plant director.

“Our universities are really becoming research-oriented, supported by a lot of high technology stuff. All of it takes electricity, a lot of it requires supplemental air conditioning.”

(Power plant sound up/under)

Michigan State’s power plant can make 55 megawatts of electricity, and during the hottest days of the summer, the campus uses all 55 megawatts. Over the next 15 years, MSU officials project the school will need at least 20 more megawatts of power. Schools throughout the Midwest are facing similar situations, as the demand for power on campus becomes too great for their aging power plants. Many are expanding their plants to meet demand. The University of Illinois is spending 60-million dollars on two new gas-fired turbines, Minnesota’s expansion will cost a-hundred-million dollars and the University of Wisconsin is building a brand-new power plant at a cost of 200-million dollars. Some schools, including Michigan State, are also considering buying more power from their local utility companies. But MSU power plant director Bob Ellerhorst says that electricity is almost twice as expensive as power produced on campus and isn’t nearly as reliable.

“Campus didn’t have a single outage, we had a lot of equipment failures in the plant that we just deal with. The campus has not had an interruption to service in over 36 months. I think that’s a lot longer than you’ve had to reset your clock at home.”

Michigan State is also looking into whether alternative sources of energy, such as wind and fuel cells, could play a part in a long-term solution. But in the meantime, they’re hoping students and faculty will begin conserving energy to help reduce demand and cost.

(Sounds of dorm up/under)

But that could be a challenge, from the looks of things at dorms and buildings on college campuses throughout the Midwest…where more electricity is being used than ever before.
