There is a man-made canal that connects
the Mississippi River system with the Great
Lakes. The Chicago Ship and Sanitary Canal
makes shipping cargo between the waterways
possible. It also makes it possible for invasive
pests in the water to invade both systems.
The big concern right now is a big, nasty group
of fish known as Asian Carp that’s already
invaded the Mississippi and some of its
tributaries. An electric barrier has been built
in the canal to try to stop the fish from getting
into the Great Lakes. Lester Graham talked with
Jennifer Nalbone about the problem. She’s the
Director of Navigation and Invasive Species with
the environmental group Great Lakes United:

Jennifer Nalbone: They are just incredible eaters, and they get as big as 3 to 4 feet, 80 to100 pounds when mature. And they are just prolific. Some species, the females can produce over 1 million eggs in their lifetime. So the fear is, like they’ve done in the Mississippi River Basin, they’ll get so big, they’ll have no predators, they’ll eat so much food, and there’ll be so many that they’ll basically take over the ecosystem. In some areas, where they’ve invaded, upwards of 90% of the river’s biomass is carp.

Lester Graham: You’ve probably seen this fish on videos or something like that – they’re the ones that as a boat passes by, they’ll jump out of the river, and sometimes even hit the boaters.

Nalbone: I admit, the first time I saw a video of the jumping silver carp, I was so startled I laughed at it. But there’s nothing funny about 50, 60, 70 pounds of fish flying at you when you’re going 20 miles an hour. It could kill someone.

Graham: Now, there’s this electric barrier in place that actually shocks the water so the fish is discouraged from coming into the area. But now there’s concern that the fish has invaded a nearby river, the Des Planes River, that’s very close to this canal. So, why’s that a problem?

Nalbone: Our concern is with flooding. Just last year, we saw major floodwaters in the Des Planes River, where floodwaters connected the Des Planes and the Chicago Sanitary Ship Canal in streams of water several feet deep. And carp could be carried into the Chicago Sanitary Ship Canal in those floodwaters.

Graham: So, what are you proposing? How could we stop the fish from going any further?

Nalbone: Well, the long-term solution is hydrologic separation of the Mississippi River Basin and the Great Lakes Basin. Army Corps of Engineers has been authorized to study that problem, but that’s a multi-year project. Right now, what we’re concerned about are floodwaters this fall. We are pressing that the Army Corps of Engineers put in place sandbags or berms in the low points between the Des Planes and the Canal. And also fill in some of the culverts in the IMN Canal that connect to the Chicago Sanitary Ship Canal.

Graham: Now, I’ve watched this situation for years – long before the Asian Carp invaded the Mississippi River system – and I’m wondering, even if further millions of dollars are spent, to try to put up barricades or stop this fish, whether it’s simply inevitable that this fish will get into the Great Lakes.

Nalbone: Well, this is a battle against time right now. If we can block the future floodwaters from the Des Planes – which is probably our biggest hole in our defense right now – and plug the culverts in the IMN, we can buy ourselves some good time. But we won’t be out of the woods until we separate the Mississippi and the Great Lakes Basin. But we can’t let this invasion happen. It would be, perhaps, the greatest anticipated ecological tragedy of our time. So, I don’t think that inevitable is an option. We have to get it done.

Graham: Jennifer Nalbone is with the group Great Lakes United. Thanks, Jennifer.

Nalbone: Thank you, Lester.

The power industry wants to create
loads of low-carbon electricity. To
make that happen, they want to build
more than two dozen nuclear reactors.
Shawn Allee reports there could be
delays for at least half of those:

Westinghouse’s AP-1000 reactor was supposed to revive the nuclear industry. But recently, government regulators said they can’t say whether the current design can withstand earthquakes and other disasters.

Critics of nuclear power are pouncing on the news.

Henry Sokolski is with the Nonproliferation Policy Center. He says one government agency’s set to approve loan guarantees to build these reactors.

“If you do that, there won’t be much discipline in the industry to not screw up, there’ll be less.”

Westinghouse says it will provide the government with tests to prove its reactor is safe.

It’s not clear whether the government will delay final approval of the design.

Behind Big Oil’s Green Motivations

Some well known oil companies
are very publicly getting behind
alternative energy initiatives.
But are these serious efforts
or just a case of green-washing?
Tamara Keith tries
to get some answers:

The first thing oil giants like Exxon Mobil, BP and Chevron would
like us to know is that they’re not oil companies. They are energy
companies. So, they say, investing in biofuels, solar panels and
geothermal power really isn’t out of character… even if those things
only make up a fraction of their total business.

And I guess that’s how you end up with an electric car that says
“powered by Exxon Mobil” on its bumper.

Reiner: “So, you want to go take a look?”

Keith: “Yeah, sure.”

Vann Reiner is the CEO of the Maryland Science Center.
The center is running a pilot project, renting out a handful of
bright green battery powered cars to Baltimore residents and tourists.

Reiner: “Here’s the gas cap.”

Keith: “It’s an outlet.”
Reiner: “It’s an outlet, that’s right. And you see it’s 110 volt
15 amp – so household current.”

The cars use a battery that employs a special polymer film developed
by Exxon Chemical.

“So, you turn the key the way you normally would.”

(sound of car)

Exxon Mobil said it couldn’t make anyone available to be
interviewed for this story.

Reiner: “Nice job on acceleration.”

Keith: “Thank you.”

So I asked the science center’s Reiner what I wanted to ask
the folks at Exxon Mobil. Why in the world is an oil company
promoting an electric car? Isn’t that like working to put themselves
out of business?

“I see it as a technology company who has made a lot of money
in oil, no getting around that. But what else can you do? And
this is a way to insure their future, in my opinion. But I’m just
delighted that they chose us.”

Exxon Mobil also recently announced a 600-million dollar investment
in algae as a future biofuel – and the company is making sure we all
know about it with with newspaper and television ads.

“And they absorb CO2. So they help solve the greenhouse problem as well.
We’re making a big commitment to finding out just how much algae can help
to meet the fuel demands of the world.”

Still, Exxon Mobil is planning for oil, gas and coal to continue dominating
the world’s energy supply for at least the next 30 years.

Alex Yelland is with Chevron, and he says that’s what his company is projecting, too.

“Renewables is currently around 10 percent of the energy mix, and, in the
coming decades, that’s not expected to change a huge amount but from its
current state it’s relative state, it will grow significantly.”

Over the next 2 years, Yelland says Chevron plans to spend 2-point-7
billion dollars on renewable energy and energy efficiency. But Yelland
insists that kind of investment in energy sources other than oil isn’t
counterintuitive.

“For us, it’s about building a sound business for the future and
understanding where global demand is going and how we can meet that.”

“I think it definitely is smart PR.”

Edward Wu is with Cora Capital Advisors in New York. His firm specializes
in alternative energy investing. He says these companies are worth hundreds
of billions of dollars and, by comparison, their green investments are fairly small.

“They’re not going to replace oil, but I think they’re hoping that
they’ll be somewhat economically viable and at the same time definitely
serve a PR purpose right now.”

But Wu says the sprinkling of investments isn’t just about having something
to talk about in their ads.

“They want to have some biofuels in the mix. They want to have some battery
companies in the mix. They’re essentially dipping their toe in the water to
essentially hedge their bets.”

Because no one will want to be an oil company if, or perhaps we should say when,
oil stops dominating the energy landscape.

Tar Sands Get Tripped Up

American gasoline refineries are
expanding to process a dirtier kind
of oil. Shawn Allee reports
one company’s plans hit a snag:

The BP fuel refinery in Northwest Indiana wants to process more Canadian tar sands oil.
Processing tar sands crude creates more air pollution than normal. The federal
government wants more air pollution figures from BP before signing off on an air
permit.

Groups like the Natural Resources Defense Council pressed the government to step in.
The NRDC’s Ann Alexander is glad BP’s tar sands project is getting scrutiny.

“If tar sands are going to be developed, we think it’s it’s critical they be developed in
a way that complies with the Clean Air Act, because the Clean Air Act is there to
make sure it’s not the community that pays for development of tar sands through
increased pollution and the health problems that result, but that it’s BP who pays
those costs.”

BP’s tar sands oil project in Indiana is just one of several going on in the Midwest.

Fuel From Abandoned Fruit

  • Every year, 20% of the watermelon crop never makes it to buyers. Wayne Fish hopes to turn some of this waste into ethanol. (Photo by Gail Banzet)

Every year in the US, more than 750-
million pounds of watermelon rot away
in the fields. Those left behind can’t
be sold because they’re sunburnt, diseased
or damaged, but now scientists in Oklahoma
are working on a way to use the abandoned
fruit. Gail Banzet reports:

Growers say it was a pretty fair season for watermelons in 2009. A lot of ripe, juicy
melons were enjoyed during the summer months, but, every year, 20% of the crop
never makes it to buyers.

(sound of driving)

Research chemist Wayne Fish steers his truck around the USDA’s agriculture research
laboratory in Lane, Oklahoma.

There are 320 acres of different crops and vegetables here, and one acre is dedicated
to watermelons. Workers have already picked the good ones. Those that are left are
discolored, misshapen or damaged by raccoons or birds.

“There’s one where a crow has pecked on it. That melon is over-ripe, so it has
two strikes against it.”

But Wayne Fish says that watermelon can still be used.

“It’ll still make ethanol fine.”

Four years ago, the National Watermelon Association started studying the ethanol
potential of watermelon sugars. When the project showed favorable results, a trial
process began at the research station in Oklahoma. Bob Morrissey is Executive Director
of the National Watermelon Association.

“If you’ve got that fully developed watermelon there, it has all of the components
– the water, the sugar and the fiber – to create ethanol.”

(sound of machines in a lab room)

Back at the research station in a lab, Wayne Fish and his team combine yeast with
watermelon sugars. Hours later, the mixture is fermented and placed in a still.

“By distilling that mixture, one drives the ethanol off together with a small
amount of water. That’s how we enrich the mixture to ultimately 95% ethanol.”

Fish says the project is not an attempt to replace sugar cane or corn for ethanol. This
pilot phase of testing shows wasted watermelons can add some ethanol to the overall
market.

Bob Morrissey at the National Watermelon Association says using the melons could
open up a whole new market for farmers. They could sell the good ones to people and
the bad ones to ethanol plants.

“That farmer could literally harvest his or her entire crop, send it to the ethanol
plant, and at least get something out of it to try and cover their cost instead of
taking a complete loss.”

There are a lot of growers across the country who are worried about wasting melons.

Jim Motes is from Oklahoma. Even though he’s not a huge farmer, he says he’s always
looking for ways to make the most of his crop.

“If they can find a large enough quantity to make it efficient, then it’s a good idea,
because there are a lot of watermelons laying there when the field disked up that
ought to find some use.”

Researchers say watermelon ethanol is drawing a lot of attention. A Texas-based
company Common Sense Agriculture is currently working on a mobile unit that would
process the melon sugars and produce ethanol right in the field.

Sam Pulcrano is the Vice President of Sustainability at the Postal Service. He says, over the next six years, they’ll cut fuel consumption by 20% and energy use by 30%. They’re already doing energy audits of the 500 largest postal facilities.

“And where it makes business sense, we’re replacing things like roofs, the HVAC systems, replacing windows with more energy efficient windows and lighting with high-efficiency lighting.”

Graham: “There’s been some consideration of eliminating Saturday delivery. Is that figured into your calculations on reducing greenhouse gases?”

“It will if and when Congress gives us the ability to do so.”

Lessons From a Skyscraper

Tower. But there’s more changing for
America’s tallest skyscraper. Soon,
the Willis Tower will start an environmental

You might have heard the Sears Tower
in Chicago is now called the Willis
Tower. But there’s more changing for
America’s tallest skyscraper. Soon,
the Willis Tower will start an environmental
facelift that could cut eighty-percent
of its energy use. You might wonder:
what could a homeowner learn from what
the Willis Tower is doing? Shawn Allee thought it wouldn’t hurt to ask,
and went on a tour for the answer:

One of the co-owners of the Willis Tower is John Huston. He says there’s plenty for
people to learn from the tower’s green rehab plans. To start – we’re at the base of the
tower, and we’re craning our necks up.

“We’re facing north. We’re looking at a hundred and ten floors, so that’s 16
thousand windows in total.”

Huston says those windows are the old single-paned kind common in 1974 – back
when the Willis Tower was finished. In the summer, the windows let heat in, and
during the winter, they let heat escape. And that black metal you see in photos? It
does the same thing.

Huston: “The building is clad in aluminum if you went outside in the winter, you
certainly wouldn’t want to wear an aluminum ski jacket.”

Allee: “You’d freeze.”

Huston: “Exactly.”

So, Huston says the first thing they’re gonna do at the Willis Tower is what he calls
“tighten the building’s envelope.” It means insulating the building from the outer
walls and replacing the windows – all sixteen thousand of ’em.

“It’s an incredible job. That’s what we have to change in order to conserve the 80%
of energy that we anticipate doing.”

Huston says energy consultants pretty much give homeowners the same energy
advice. He says, the nice thing is, once you do that it’s easier to figure out what’s
next.

“Watch your step.”

Huston takes me into the guts of the Willis Tower. This is where it’s heated and
cooled. He says since the building’s gonna waste less energy, he won’t need such
powerful equipment.

Huston: “A lot of what’s in here will disappear or shrink.”

Allee: “So what is this?”

Huston: “This is an electric boiler. It provides hot water to heat the building. Each
one of these consumes enough electricity to heat and light a town of 6,000 people.
We have eight of these throughout the building. It’s not just the boilers. in this
section behind us, you have all the pumps that move hot water throughout the
building. Each one of those pumps is hooked to an electric motor, and 50% of them
can be eliminated.”

Huston says the take-away here is that once a building requires less energy to heat
and cool it, the other savings can kind of cascade from that.

But there’s another lesson homeowners can learn from the Willis Tower’s green
rehab.

The architecture firm that planned this project is called Smith and Gill. Gordan
Gill tells me, their work was made easier by the fact the Willis Tower owners keep
records of their power use.

“When you’re designing something new, you’re predicting the performance of
something. Here, you can actually test it, since you have records of how much
energy was spent, how much energy was used – you know where you stand, exactly.
And so now, you can do mock-ups and tests and things like that.”

Gill says that’s a good reason for homeowners to hold onto their power and heating
bills, too. He says if you’re confident in your actual costs and likely savings, you’re
more likely to follow through with your rehab project.

“And that’s important because you’re avoiding the obsolescence of these buildings,
and I think that’s true from everything like Willis to people’s houses.”

The White House has released a plan that
intends to get more people to make their
homes and apartments more energy
efficient. Mark Brush reports:

One of the main goals of the “Recovery through Retrofit” plan is to find ways to help people pay for energy efficient improvements. Some of these improvements can cost a bundle.

But, the White House says, there are ways to help. Christine Glunz is a spokesperson for The White House Council on Environmental Quality:

“We want to provide American homeowners with the opportunity to get this energy efficiency done, and get the retrofit done, without having to bear a major financial burden immediately.”

Glunz says the Obama Administration is pushing for new financing options. One they support is a local government loan program that is paid back through property taxes.

In addition to financing, the plan calls for an energy label for homes and apartments. It’s sort of like an Energy Star label, so renters and home buyers can figure out how efficient a building is.

The plan also calls for more trained workers to perform energy retrofits.

Going ‘All-In’ on Goat Farming

A lot of companies have been slowing
down and cutting back because of the
economy. But tough times aren’t
stopping some new businesses in the
midst of the ‘local food movement’
from moving forward. More than a
year ago, Julie Grant spoke with the
owners of a goat cheese farm. She
visited them again this year. Now,
they’re opening a new creamery, despite
lots of economic obstacles:

Abbe Turner just quit her day job. She’s had a good-paying
university job – with benefits – for many years. But today
she’s waiting for the delivery of a $5,000 dollar pasteurizer.

“There we go. There’s my pasteurizer.” (cheering)

The truck arrives with a six foot round stainless steel tank.

“I never thought I’d be so excited by a 3,000 pound hunk of
metal in my entire life. But…” (laughter)

Abbe and her husband, Anderson Turner, started dreaming
of goat cheeses three years ago. This big hunk of steel will
help them finally to get their creamery off the ground.

“The pasteurizer will allow us to make cheese in small
batches, artisan cheeses. We’ll do some cheves in the
pasteurizer, some tommes and probably a goat gouda.”

The Turner’s dream started after they bought a few goats for
their hobby farm. They made a little cheese for the family.
And they liked it. So they kept getting more and more goats.

Now they have more than 160 Nubians, La Manchas, and
Alpines. Abbe and Anderson had been getting up before
dawn every morning to milk them. By hand. Then they
would get their 3 kids ready for school and head off to their
full-time day jobs.

The Turners wanted to automate milking, to make things
easier and faster. They even had a group of 23 investors
chipping in to renovate their barn into a milking parlor. But
that was last fall.

“Unfortunately, with the stock market crash, the calls kept
coming in. ‘Hi. We really believe in what you’re doing.
Unfortunately, I’m watching my investments tank and a goat
cheese operation is not something I can write a check for
right now.’”

Some people thought it would be smart to forget about
starting a new creamery in the midst of a recession. Matt
Ord used to sell the Turners feed for their goats. But he had
to shut down his family business when the economy
crashed. Now he’s working with Abbe to build her goat farm
and creamery – even though he’s not convinced it’s the right
time for this kind of venture.

“She’s nuts. But I hope everything goes good for her, I really
do. She’s got a lot of patience and a lot of nerve starting this
business right now. It’s a very scary time. And I know
things are very tough for everybody.”

Abbe likes to think of her family as bold, rather than nuts.
And most of her investors have come back on board since
last year.

Her husband Anderson Turner is glad she’s starting full-time
to get the creamery off the ground instead of waiting for the
economy to turn around.

“I can’t think negatively about opportunity. My time is now.
My opportunities are now, my life is now. So, this is the
cards I’m dealt with. I’ve got to deal. So, let’s go.”

The Turners believe that the local food trend is just getting
off the ground, and that support for local foods will more than
compensate for the tanked economy. They say restaurants
have already put in orders to buy their cheeses.

Now all they have to do is start making it.

The Environmental Protection Agency
is holding up nearly 80 permit
applications for coal mining projects
because of concerns about about water
quality. Tamara Keith
reports this is creating a different
kind of concern in Appalachian coal
country:

The applications involve mountain top removal coal mining. Explosives are used to get at coal that’s close to the surface.

In the past, the mining companies have been allowed to fill in valleys with the leftover rock and dirt. But the EPA is concerned that streams are getting buried and polluted so the agency is now giving that practice a serious second look.

Carol Raulston is with the National Mining Association. She says holding up those permits have people in the mining towns of Ohio, West Virginia, Kentucky and Tennessee worried about losing their jobs.

“You really can’t operate these mines and employ people at them unless you’re able to construct the fills and in many of these communities they are the sole employer.”

An EPA spokesperson says protecting drinking water and coal mining jobs are both important. The agency says both can be done.
