You might be hearing about geothermal energy more and more. But what exactly is geothermal energy? The new federal Energy Act calls for more research and investment into the alternative energy source. Robbie Harris has more on this long used, but little known technology, for tapping the earth’s heat:


(“Now look at that!” “Wow!”)


(whooshing of geyser)


In Iceland, where geysers gush from the ground and steam rises from the bays, geothermal is the number one source of energy. This island nation in the north Atlantic burns virtually no fossil fuel to heat or cool its buildings.


“You will probably not see a building that is not heated by geothermal
energy during your visit here.”


Pall Valdimarsson is Director of Research and Development with Enix. It’s Iceland’s largest geothermal consulting firm.


“And I myself, I have never lived in a house in Iceland without geothermal
energy, not in my whole life and I am not the youngest one as you can see.”


Valdimarsson says Iceland has used a special technology to tap earth-generated heat since the 1930s. And why not? It’s everywhere on this volcanic island. The first settlers here in the eighth century saw what they called “smoke” rising from the hot springs.


Today, steam blasts from hot water wells at Iceland’s newest, state of the art geothermal plant. The steam spins turbines to make electricity. The superheated water is piped directly into buildings where it gives up its heat. This heat exchange is the core concept behind geothermal technology.


Hans Bennimidgel is a spokesman for the power plant. He says the benefits for Iceland are simple:


“Clean energy and dirt cheap.”


Few places have the hot water resources Iceland has. But according to the Geothermal Resource Council, superheated water is available virtually anywhere in the world, if you drill deep enough.


The U.S. already taps this underground hot water to produce more geothermal electricity than Iceland does. And that’s expected to grow sharply, but for decades Americans have also used a different form of geothermal energy to heat
and cool buildings.


Erik Larson is a vice-president of Indie Energy. He calls it the other geothermal, which is, basically:


“Free heat from the earth and an extremely efficient way to eject heat from
the building in the summer time.”


Larson says geothermal, or geo-exchange systems, are comparable to traditional
heating, ventilation and cooling systems. But they use the earth’s constant underground temperature — around 55 degrees in most of the U.S. — to take the edge off a building’s heating and cooling load:


“Geothermal heat pump technology like we’re talking about can be done
anywhere in the country. Anywhere where there is ground to drill we can
put in our closed loop wells to draw heat from the earth to provide an HVAC
system.”


For a long time in rural areas, large horizontal loops several feet
underground captured and released heat. But in urban areas, there wasn’t
enough land. Now Larson says Indie Energy uses a new drilling technique
known as a vertical closed loop system. He says they can be installed under
almost any building. Pipes inside wells hold a fluid, which continuously
circulates between the ground and the building — creating a heat exchange.
Larson says a geothermal system saves owners money:


“We are a system that you would fully own through the ground loops or these
wells that we put in…through the distribution which is basically happening
within your building. So it adds value to your property, you control it and you
take advantage of all the savings.”


Larson says geothermal systems for buildings cost anywhere from 50 to 100 percent more than a typical heating, cooling, and ventilation system. But he says, most pay for themselves in five to eight years with the energy savings.


Business is booming. Larson says Indie Energy plans to expand in two new locations this year. Four months ago, they installed a large geothermal system at Boocoo Community Center in Evanston, Illinois. During the installation, they helped train new workers in geothermal technology. It was a joint project between Indie Energy and Boocoo. They’re training workers for a new green industry they hope will not only save resources, but create new jobs.

Local Blowback From Wind Farms

America’s hunger for new, greener sources of electricity, and a generous
federal tax credit, are fueling a wind power boom. According to the
industry, almost 6,000 megawatts of new wind energy are under construction
nationwide. That’s 40% of all existing wind power in the U.S. The federal
government doesn’t regulate many aspects of wind power. Neither do many
states. That puts a lot of pressure on local town councils to decide if a wind
farm will be a good neighbor. David Sommerstein reports:

America’s hunger for new, greener sources of electricity, and a generous
federal tax credit, are fueling a wind power boom. According to the
industry, almost 6,000 megawatts of new wind energy are under construction
nationwide. That’s 40% of all existing wind power in the U.S. The federal
government doesn’t regulate many aspects of wind power. Neither do many
states. That puts a lot of pressure on local town councils to decide if a wind
farm will be a good neighbor. David Sommerstein reports:


It’s 7:30 in the morning on a crystal clear day in northern New York State.
A dozen ironworkers huddle between two monstrous red cranes and one
gleaming white tower, rising 22 stories tall:


“Everybody know their tasks? Anybody got any questions? Got a beautiful
day to fly this thing. No wind.”


Today the crew’s going to lift the thing you see spinning on a wind turbine –
three blades twice the length of semi trucks – to the top of the tower and
attach it. Dave Talley’s the supervisor. He’s from Petersburg, Tennessee:


“I live 20 miles from the Jack Daniels distillery.”


Talley’s helped build some of the wonders of the modern world: the
monorail at Disney World, the world’s largest furnace, the largest stamping
press.


“Yeah, we got a saying in our business. My work is my play, my play is my
work. I work harder than I play, and I play hard. If it ain’t hard, I ain’t
playin’. If it ain’t fun, I ain’t sayin’. And that’s all I’m sayin’.”


The cranes ease the blades into the air. Talley’s crew will do this 122 times
to erect Noble Environmental Power’s wind farm here. Noble’s owned by JP
Morgan Partners. The company spent millions of dollars and years of
permitting and negotiating to get to this point.


The wind farm touched off a fiery debate in town. Local board meetings
erupted in yelling. Neighbors and families became estranged:


“I think there’s a lot of people who have family members who totally fight
over it. I mean my sister and I don’t. We just don’t discuss it.”


Julie Ribot can see the turbines from her porch. Her sister works for the
wind power company. Ribot, however, is dead set against them:


“I don’t want to live here. There’s supposed to be 27 going up across the
street alone. Somebody said, ‘oh, it’s just like a ceiling fan.’ Well, would
you want 27 ceiling fans going off in your living room? No.”


Just next door to Ribot, Richard Widalski thinks they’re great:


“We do have to find an alternative source of energy. The price of oil and
everything, it’s getting ridiculous. I was told it’ll put up 1.5 megawatts of
power, which will, y’know, supply power for quite a few homes.”


Wind developers pay landowners thousands of dollars a year for hosting
turbines on their land. But neighbors have to live with the windmills, too,
and they don’t get paid. Planner John Tenbush says money pits haves
against have-nots in a small town:


“One guy’s gonna get a lot of money and the guy right next door, who’s
going to suffer from the noise or the blinking effect or some other adverse
impact, gets nothing.”


Across the country, industrial-scale wind project are forcing small, mostly
rural town councils to make big decisions. The federal government and
most states offer little guidance on a blizzard of complicated issues: how far
should the turbines be from a house or a road? How loud can they be? Do
they boost or blemish property values? Do they kill too many birds?


David Duff is on the planning board in nearby St. Lawrence County. He
says it’s easy for town councils to get in over their heads:


“Maybe they buy snowplows and they put out contracts for salt. They are
not in the same league in terms of negotiating as a multinational company
who has done this before.”


Until regulation catches up, the burden falls on local town councils when
wind power moves in.

The price of crude oil has reached a record high. Some people are expected
to feel this blow harder than others. Kyle Norris has more:


A barrel of crude oil costs a record one hundred dollars. Everyone is feeling
the results of this rise at the gas pump. But researchers say it’s hitting some
people especially hard.


Nancy Cain is a spokesperson with AAA:


“Who it really hurts is really the quote-unquote working poor. The people that
really are working jobs just making it, getting by, week to week. They’re
spending more and more of their money and they have less available cash
than some other people do.”


She says that rising gas prices link to rising grocery costs. Which also have
serious consequences for the working poor.

University students are sniffing manure samples in the lab. As Mark Brush reports, the
students are part of a research effort aimed at reducing odors near livestock farms:


Students are paid thirty dollars to take part in each sniff test. They tell researchers
which air samples smell the worst. Researchers are trying to figure out how to cut back
on smells coming from large livestock operations.


Al Heber heads up the research at Purdue University. He says the studies help determine
what practices cut down on smells – and it helps communities decide where to locate
these big livestock operations in the first place:


“We have used these odor emission studies to help develop a setback model. So that if
the farm is located far enough from the neighbor then we can avoid the problem because
we let the atmosphere dilute the odor down to where it’s not a nuisance anymore.”


Heber says using appropriate setbacks could cut back on the conflict between livestock producers and the people who live near them.

California Sues Epa

Environmental groups are lining up behind California in a lawsuit against the
Environmental Protection Agency. Lester Graham reports, the EPA is trying to stop
California from mandating stricter greenhouse emission standards for cars and
trucks:


The Sierra Club, the Natural Resources Defense Council, Environmental Defense
and other big environmental groups have filed a petition with an appeals court. They
want to overturn a decision by the EPA. As soon as President Bush signed the
Energy Bill into law, the EPA Administrator said the new 35
mile per gallon standards in the Energy Act would reduce greenhouse gas emissions
enough that California’s stricter emissions standards were not necessary.


In response, California and 15 other states sued the EPA. California often leads the
nation in stricter pollution reduction standards. The Sierra Club called the EPA’s
decision – quote “another example of the Bush administration’s bad habit of ignoring
laws that is finds inconvenient.”


The EPA argues the better mileage standards will adequately lower greenhouse gas
emissions because less gasoline will be burned.

Preserving Cultural Remedies

  • Faith learned about the use of many herbs for home remedies from her father in Louisiana when she was a small girl. (Photo by Kyle Norris)

When most of us get sick we go to the doctor and get medicine. But
some people are holding onto the old ways of healing. And many
people think we could learn a lot from the old ways. Kyle Norris has
this story:

Transcript

When most of us get sick we go to the doctor and get medicine. But
some people are holding onto the old ways of healing. And many
people think we could learn a lot from the old ways. Kyle Norris has
this story:


The small store is called Nature’s Products. It’s in a neighborhood with
a lot of abandoned buildings and store-front churches. When you walk
inside the store, the smell of incense clings to your clothes.
Green plants hang in the windows, and there are jars and jars of bulk herbs lining
the shelves.


Gary Wanttaga opened the store thirty years ago. He’s always been
interested in natural healing techniques and herbal medicine. That all
might sound new-agey, but this place is not new-agey at all. The
reason Wanttaga opened the store in his hometown of Detroit was
because he wanted to help the people who lived here:


“In lot of urban areas people are very limited on resources. They’re limited
with money. They’re limited with shopping resources. And this is one way
that I try to give back to the community”


Wanttaga says one of the main reasons he’s stayed in Detroit is because of
his customers. They’re some of his biggest teachers. Many of his
customers are older African-Americans. They came from the South to work
in the factories during World War II. When they came they brought with
them a cultural knowledge of herbs and natural healing techniques.


One of his customers is 72-year-old Faith. That’s her legal name – just
“Faith.” She grew up in a segregated farming community in Louisiana. Her
father was a farmer, and he taught her all about the herbs:


“I’m the youngest child of all, so I’m the baby. And he would often let me
ride on his shoulder. And sometime I’d be saying ‘Papa, what is this?’ and he
would tell me what that was, we’d be walking through the fields and he
would tell me what was, and he would tell me different things, what you use this for
what you use that for. I had 100 questions. Boy, I was a kid I had a 100
questions.”


She says back then, everyone knew about the herbs, and everyone used
them. At that time, people who were poor or black or who lived in rural
areas did not often have the option of going to a doctor. And so they turned
to the plants and trees around them for medicine, and they developed a great
knowledge about what did and didn’t work to keep people healthy:


“The pine tree was used for many things. Because it’s one of things where
you get turpentine from. It was definitely used for healing. And we used
turpentine for sores. And it works today! If you get a cut and you put
turpentine on it immediately as soon after you hit it, it will never be sore.”


Herbs were out first form of medicine. That’s what Suzanna Zick says.
She’s a naturopathic physician who teaches at the University of
Michigan. She says we have a collective knowledge about herbs that’s
thousands of years old. She says when you compare that to what
modern-day science knows about herbs, it’s not much of a comparison:


“In a sense we have just a tiny little window that science shows us, as
compared to the long use.”


Zick says we could learn a lot from these folks and the knowledge they
have, but not many researchers are studying people like the customers
here in Detroit:


“I think that we can actually learn what herbs they’re using a lot of and
what for. Because I think those are probably the ones that would be of
most interest. In particular, it’s a good question too if they’re using
them with conventional medications, it’s for safety issues. But also if
this is their primary health care for some of them, if it’s working, then
this is a very inexpensive way of providing health care for people who
might otherwise get none.”


Everyone we heard from in this story said the same thing. For us to
have good health, the old-school ways of healing can work hand-in-
hand with modern-day doctors and science. But the people who know
about the herbs are growing older and dying, and their knowledge is dying with them.

Nail Salon Workers Exposed to Fumes

Anyone who’s been in the same room as an open bottle of nail polish remover
knows how strong it smells. Now imagine working in those fumes all day, every
day. That’s what it’s like to work in a nail salon. There’s growing concern that nail

health is at risk. Ann Dornfeld reports on a project in Seattle to teach nail

Anyone who’s been in the same room as an open bottle of nail polish remover
knows how strong it smells. Now imagine working in those fumes all day, every
day. That’s what it’s like to work in a nail salon. There’s growing concern that nail
salon workers are being exposed to such high levels of these fumes that their
health is at risk. Ann Dornfeld reports on a project in Seattle to teach nail
technicians how to keep themselves safe at work:


Connie Fields is at Northbend Nails today to get her nails touched up with liquid
acrylic. It’s been her ritual every two or three weeks for the past twenty years.


“Y’know, I work a lot with my hands and when my nails are done it makes
me feel good. It helps complete my dress, so I like nails. (Laughs)”


Still, Fields has her misgivings about the safety of nail products:


“I’ve had concern! Because years ago, whatever the chemical they were
using at the time, some girls had an infection.”


It’s not just the costumers who are at risk. The people who work with these chemicals day in and day out are the most exposed. Often, they’re Vietnamese immigrants. It doesn’t take long to get trained to
do nails, and you don’t need to speak much English. But language barriers can
keep Vietnamese nail salon workers from learning how to protect themselves
from workplace chemicals.


You’ve probably noticed this sounds less like a spa, and more like an auto body
shop. That’s how it smells, too. Salon owner Helen Hoang is combining
chemicals to create liquid acrylic for Connie Fields’ nails:


(Translated from Vietnamese:) “I use two products for this. One product is mixed with powder to make the
powder supple so I can paint it on. And the other one is a polymer to finish
it off.”


The odor is industrial-strength. And Kevin Burrell says that’s no exaggeration:


“The chemistry that’s used in the salon for doing nail finishes are very
similar to the chemicals that are used in auto manufacturing.”


Burrell is the head of the Environmental Coalition of South Seattle. He says most
nail technicians don’t realize that they’re doing a small-scale version of auto
painting, with the same kinds of chemicals and technique: a primer, a base coat
and a top coat.


Common chemicals in nail polish include formaldehyde and toluene. At high
doses, those can cause respiratory problems including asthma, headaches, and
even organ damage. Burrell says acrylic nails might be even more dangerous:


“They’re made of two chemicals, one of which has been banned at full-
strength in our state. You can’t use methyl methacrylate in Washington
State at 100% strength.”


But Burrell says products with 99.9% percent methyl methacrylate are still on the
market. That chemical has been limited or banned by at least 30 states. Studies
on animals suggest inhaling too much of it may cause respiratory and organ
damage. A recent University of Toronto study showed that a group of nail salon
workers’ children had signs of learning disabilities linked to solvent exposure.
And some studies show a chemical in nail polish called dibutylpthalate may stunt
the fetal growth of male testes.


Burrell says to limit exposure, nail salon workers need to use safe chemical
handling practices. So his organization is working on an education
campaign called Toxic Beauty. It’s funded by the Environmental Protection
Agency. The campaign sends a Vietnamese-speaking educator into salons to
show owners and workers how to protect themselves.


At Northbend Nails, owner Helen Hoang welcomed the advice. She already had
a ventilation system and air conditioning:


(Translated from Vietnamese:) “There’s probably just a few places that have ventilation systems because
they’re costly. It takes money to buy them and to run them. I don’t know for
sure, but my customers say the air is much better here than other salons.”


She says the educator showed her some other ways to limit chemical exposure:


(Translated from Vietnamese:) “Before, I threw everything away in just the trash can. They told me to put
everything in trash bags and tie them before I throw them away. Another
thing they recommended was to install vacuums in the manicure tables to
suck up the dust and fumes. I’m planning to do that.”


Ultimately, environmental justice activists want to nail salon
workers and customers to demand safer nail products. Pthalates, formaldehyde
and toluene have all been banned by the European Union in nail products. So far
only one major company, O.P.I., has agreed to change its US formulations, too.


The demand has to come from the ground up. That’s because the US government doesn’t regulate cosmetics for safety.

Wolf Hunting Hurts Wolf Packs

ranchers to kill wolves during specific seasons, or even year-round. But scientists and

This year, the U.S. Fish and Wildlife Service plans to officially remove the northern
Rockies gray wolf from the federal Endangered Species List. The agency will hand over
management of the wolves to states in the region. The states will allow hunters and
ranchers to kill wolves during specific seasons, or even year-round. But scientists and
conservationists are concerned about the hunting plans. Kinna Ohman reports some
conservationists think hunting could disrupt the way a wolf pack works, and even lead
members to seek out easier prey such as livestock:


Biologists in Yellowstone National Park have had an unprecedented opportunity to study
wolves over the last twelve years. They’ve looked at everything from what wolves prefer
to eat, to why wolves kill big prey such as bison. But one topic they haven’t studied
much is how a typical wolf pack works.


Doug Smith is a biologist with Yellowstone’s wolf recovery program. He says they now
understand healthy wolf packs need lots of older, skilled members in order to hunt natural
prey:


“They’re very good at it. They have a lot of teamwork. They switch back and forth
about whose doing what job.”


In fact, studies have shown it takes 3-4 skilled adults to kill an elk. It takes more wolves
to kill a bison. Packs in Yellowstone are naturally filled with large numbers of adults.
But in places where wolves are hunted by humans, skilled adults are in short supply.


Smith says a lack of skilled wolves in a pack could mean they’d be more likely to go after
easier prey including livestock:


“If they don’t have that experienced age structure in the pack, they make do, and so
you will have probably inexperienced killers out there and inexperienced killers are gonna
look for easier prey. The elders of the pack, if there are only 2 or 3 of you,
are much more likely going to go after a sheep or cow than if there’s 7 or 8 of you.”


These concerns could become real when the gray wolf is taken off the Endangered
Species list in the northern Rockies. The states of Montana, Idaho, and Wyoming will
take over management. Suzanne Stone with the Defenders of Wildlife in Idaho says
hundreds of wolves could be killed as part of state management plans:


“They’re talking about killing now about 500 to 600 wolves after delisting. You
don’t manage any population of wildlife like that. The delisting plan, as it’s written
right now, is just a recipe for failure.”


Stone says the gray wolves were protected to build healthy populations, and how a wolf
pack works should be part of that consideration.


But the government is focused on how sport hunting effects just wolf numbers. Ed Bangs
is the wolf recovery coordinator with the U.S. Fish and Wildlife Service. He says that
hunting won’t threaten the wolves:


“One thing that does happen everywhere in the world that wolves and people
overlap is that people kill wolves. And the answer is yes, that does have an effect on
wolf pack structure. And it certainly never endangered wolf populations.”


So it’s hard for conservationists to convince officials that the sport hunting of wolves
could change how wolf packs work and even lead to more livestock conflicts. Biologist
Doug Smith says that’s because the decision to delist the wolves is based purely on
numbers:


“Delisting is entirely numbers. Some conservation biologists have made the
argument that delisting should not occur until the endangered species is integrated
back within the ecosystem and functioning as a member as that ecosystem. That is
not how delisting occurs now for the Fish and Wildlife Service. It’s ‘do we have
enough?'”


Many conservationists and activists will soon be arguing that killing 500 to 600 wolves
leave too few. They’ll likely file lawsuits, stressing that the importance of healthy wolf
packs should be considered before hunting is allowed.


Ed Bangs with the Fish and Wildlife Service says he’s confident the agency has followed
the law. He says they’ll meet the requirements of the Endangered Species Act by
delisting the wolves and handing management over to the states:


“My deal with the Fish and Wildlife Service is: What is the purpose of the act as it’s
currently written by Congress, have we met those conditions for wolves, and the
answer is clearly yes and therefore we’re supposed to delist them. If people want the
act to say something different, they need to talk to their elected officials, not the Fish
and Wildlife Service.”


But the wolf’s defenders will argue the U.S. Fish and Wildlife Service as well as the
states need to understand how the wolf packs work before declaring open season on the
wolf.
