There’s a lot of wind along coastal
areas… perfect for wind turbines. But a lot
of people don’t like the idea of windmills
ruining the view. So, why not put them out
in the water, just out of view from the beach?
Projects have been planned or proposed or just
rumored off the coast of places such as southern
Georgia, Delaware, Cape Cod, and Michigan out
in Lake Michigan. There are already some off-
shore wind turbines operating in Europe. Thijs
Westerbeek is the sustainable
development expert with Radio Netherlands. He
says off the coast turbines are more popular
than wind mills on the land:

Thijs Westerbeek: “Actually, the public reaction is excellent, because the whole
‘nimby effect’ doesn’t occur. The thing where you like wind energy, as a
principle. You like this big mill turning around and producing clean electricity.
But you just don’t want it in your backyard. You don’t want the noise, you don’t
want the flickering effect of the sun shining through, you don’t want birds to fly
into this, and you certainly don’t want to see it. Now, if the wind turbines are off-
shore, and far enough off-shore, that problem just doesn’t exist.”

Lester Graham: “One of the concerns is that the windmills will be an eyesore.
Can you see them from shore, and does it disrupt the seascape for either folks
on the beach or boaters?”

Westerbeek: “Well, that just depends. The two small-ish windparks, they are in
front of the coast of the Netherlands, are pretty far-off. You can just see the tips
of the blades. So that isn’t really much of a disturbance. The two gigantic
windparks, off the coast of Denmark, are actually a tourist attraction. People go
to see them.”

Graham: “What kind of problems are they for marine animals and sea birds
when they’re off-shore?”

Westerbeek: “This has been tested by scientists in Denmark. And they counted
1.2 million birds passing through, and not one was hit. The birds just see the
turbines. That’s just not a problem.”

Graham: “What kind of problem do they pose for ship navigation?”

Westerbeek: “Until now, and I’ve checked this with the Maron Research Institute
– that’s the maritime research institute here in the Netherlands – there haven’t
been any accidents yet. And that’s mainly because windparks are typically built
on sandbanks where there can’t be any traffic. However, if they would be built in
sea-going routes, and a ship would bang into it, you have a possible disaster on
hand, because the turbine will collapse – hopefully not onto the ship – but if it
does fall onto the ship, that could be possibly disastrous. So the suggestion of
this scientist at Maron that I called was ‘don’t build any windmills in, for instance,
the North Sea, which is just too busy’.”

Graham: “How do they get the power from the windmills off-shore to shore? You
have to have some kind of cable, I assume.”

Westerbeek: “And that’s a problem. Because the further windparks are off-
shore, the more expensive it’s going to be to get that power on-shore. And with
rising prices for copper, that really is a problem. The cable could ultimately be
more expensive than the park itself. Off-shore windparks are definitely much,
much more expensive than on-shore windparks. That is a fact. But they are a
political solution. People who don’t want on-shore parks for the reasons I named
– unsightly things, noisy things – that is just solved, that problem, if you have an
off-shore park. So, yes, they are costly, and maybe too costly, but it’s a political
choice to have them built.”

The Price of Global Warming

  • Some industries are working with government to voluntarily reduce greenhouse gas emissions. People who are worried about their personal CO2 emissions can buy carbon offsets, but there are dozens of programs, making it confusing. (Photo by Lester Graham)

There’s evidence that the Earth is changing
because of global warming. Glaciers are receding.
Polar ice caps are melting. Weather patterns are

There’s evidence that the Earth is changing
because of global warming. Glaciers are receding.
Polar ice caps are melting. Weather patterns are
altered. That’s prompted some people to look
for ways to reduce their personal contribution to
global warming. Rebecca Williams reports there
are many new companies that claim to help you do
that… for a price:


Whenever you drive, fly, or ride, you’re emitting carbon dioxide. And it’s not just the way you get around. It’s also any time you turn on lights or plug into an electrical outlet. More than half of the electricity in the U.S. comes from power plants that burn
coal and that’s another major source of carbon dioxide.


It’s a problem because carbon dioxide is a potent greenhouse gas.
The vast majority of scientists agree all this carbon dioxide
that people produce is trapping heat in the atmosphere and making
the planet warmer.


David Archer is a climate scientist at the University of Chicago:


“The problem with fossil fuels is that the cost of that climate
change isn’t paid by the person who makes the decision to use
fossil energy so it’s sort of like a bill we’re leaving to future
generations.”


Some people say there’s a way to pay that bill now. About three
dozen companies and nonprofits have sprung up in the past few
years. They’re selling carbon offsets.


The idea of a carbon offset is to balance out the carbon dioxide
that you emit. In theory, you can do this by investing in
something like tree planting or energy projects that don’t emit
greenhouse gasses, such as wind or solar power.


First, you can go to one of the group’s websites and calculate
your carbon footprint. That’s all the carbon dioxide you produce
by driving, flying, and so on, in a year. North Americans have
especially big footprints.


The companies assign a price per ton of carbon that’s emitted.
You can decide how much of your carbon-emitting you want to
balance out. Then you type in your credit card number and voila… no more guilt.


Well, that’s the idea anyway.


But what if you buy a carbon offset
but you don’t change your behavior? If you keep driving and
flying and using electricity just as much as before, or maybe
more than before, you’re still a part of the problem.


“You’re absolutely still emitting the carbon. The idea is that
you’re balancing it out through reductions elsewhere.”


Tom Arnold is a cofounder of Terrapass. It’s a carbon offset
company:


“Now this isn’t the optimal solution of course – you should stop
driving. But it’s a good way that we can get you involved in the
dialogue and help you reduce emissions somewhere else.”


And you can get a little sticker for your car to show you’re in
the offsetting club. But Tom Arnold admits there aren’t a whole
lot of drivers of huge SUVs buying offsets.


“We have this nice little SUV sticker – it’s pretty expensive and
a horrible seller. Most of our members already drive passenger
cars, very efficient cars. They’re just looking for a tool to
balance the rest of their impact out to zero.”


Erasing your carbon footprint sounds pretty positive, but there
are quite a few critics of the carbon offset industry. They
point out there aren’t any agreed-on standards for what an offset
is, and prices are all over the map. So it’s not always clear
what you’re getting for your money.


Mark Trexler is president of Trexler Climate and Energy Services.
He’s a consultant who reviews the groups selling carbon offsets.
He says you do have to ask questions about what you’re buying:


“Am I putting my money into something that wouldn’t have happened
anyway? Because if somebody would’ve built that windmill anyway
or if they would’ve done whatever it is you’re putting money into
anyway, you’re really not rendering yourself climate neutral.”


Trexler says there are certification programs in the works so
consumers can know more about what they’re buying. But the people
who are buying offsets now say it feels like they’re making a
difference.


Kate Madigan bought offsets. She started thinking about it when
she was awake at night worrying about the world her new baby
would live in:


“Some people say oh, global warming, it’s going to change the
world in 100 years, but I’ll be gone by then. But I think that’s
a horrible way to look at things because we’re leaving the world
to a lot of people that we love.”


Madigan says she doesn’t think carbon offsets alone will really
solve the problem. She says she thinks it’ll take a lot of
harder choices too, like driving less and using less electricity.


Supporters say that’s the real power of offsets. It’s getting
people to talk about the role they play in global warming.

Living Entirely Off the Grid

With no power lines in sight, one western Pennsylvania couple lives pretty much like the rest of us. The Great Lakes Radio Consortium’s Ann Murray has this story of home “off the grid”:


Ted Carns is busy hanging art in the foyer of his house. While he holds a picture in place against the wall, he plugs in an electric drill.


(sound of drill)


Ted and Kathy Carns’ entire two-bedroom house uses electricity powered by the sun or wind. Their rustic stone and plank home sits on top of a steep wooded hill, miles from the nearest neighbor.


“There’s no water, there’s no soil, there’s no public utilities up here. So everything that we designed, you have to keep in mind, was done in this harsh condition.”


It’s taken the Carns twenty years to design and expand their alternative energy system. Ted, a self-described scrounger and handyman, has found many components through flea markets and friends. In fact, Kathy says their off-grid system began with a gift of shoebox-sized batteries.


Kathy: “Somebody gave us a bunch of batteries-nickel cadmium batteries. And then we started thinking about how to recharge the batteries. Thinking wind. The windmill came first.”


Ted: “It took me eight climbs to install the new windmill, I had a different one up there. The bottom of the tower I built.”


Murray: “How tall is that?”


Ted: “Seventy-six feet.”


(sound of chimes)


The metal tower now looms over the house, outbuildings and organic garden. As the wind whips the chimes at its base, the turbine blades whirl and drive an alternator to generate electricity. The electricity is stored in a bank of batteries.


Murray: “Is the wind consistent here?”


Carns: “Winter good. Summer not. Then in summer the solar panels kick in. So it just sort of balances out.”


The Carns’ rooftop solar panels accept sunlight into silicon chips and convert the light into electricity. Because it’s sunny today, Kathy can run their specially manufactured clothes washer with solar energy. First, she pushes a button on the living room wall and a red light starts to blink. The light indicates that stored electricity is being converted from a DC to AC current.


“That means the house is on 110 power. Turn the water on and then just… It’s on.”


The Carns also vacuum when the sun shines or the wind blows. They run their TV, stereo and lights off 12-volt DC batteries, much like a car. They heat their water with solar energy in the summer and wood in the winter. And warm their house with a wood stove. They also capture air from underground and use it to refrigerate food and cool their house. All told, Ted and Kathy have spent about 3,000 dollars to upgrade their alternative energy system. Ted says, except for burning wood, the system is nonpolluting. He believes it’s also pretty much hassle free.


Carns: “There’s no inconvenience that we’ve seen… There’s maybe two or three days that we don’t have ample hot water. The nice thing about that is that it – you never stop appreciating the conveniences because periodically for a very short time sometimes you have to do without.”


Perez: “More and more people are discovering that they can power their homes and small businesses using solar and wind.”


Richard Perez is the founder and publisher of Home Power Magazine. Perez says states are doing far more than the federal government to encourage the residential use of renewable energy.


“There are tax credits, there are rebates, there are buy-downs. Every state has a slightly different scheme but most states have some sort of financial incentive for installing small-scale renewables in your home.”


Perez says homeowners don’t have to wait wait for government support to set up a system. Ted and Kathy Carns agree.


(sound of plates and silverware)


As the couple gets ready for dinner, Kathy says they want to inspire the many people who come to see how they live off-grid.


“We have a friend who has a solar lawnmower now. We have friends in Philadelphia that took some solar panels; it’s not their total system, but it’s a little part of their system. If we get enough company and enough people have been here, it sort of branches out, and goes off.”


An estimated 180 thousand households in the United States generate some or all of their own electricity. But alternative energy systems aren’t for everybody. For people who are downright afraid of technology or inconvenience, life off the power grid isn’t a real option just yet.

Congregations on Energy-Saving Mission

  • Father Charles Morris installed a solar-wind hybrid system to make his parish less dependent on fossil fuels for energy. Other congregations across the country are taking similar steps to be more energy efficient. Photo by Arthur Cooper.

Even before September 11th, energy policy was being fiercely debated in the U.S. Now, such a policy has taken on even greater importance, and President Bush is again promoting what many environmentalists view as an outdated energy plan. They say his focus on renewable energy is insufficient. And protest against the plan is gathering speed. But some may be surprised at who’s helping to lead the way.

Even before September 11th, energy policy was being fiercely debated in the U.S. Now, such a policy has taken on even greater importance, and President Bush is again promoting what many environmentalists view as an outdated energy plan. They say his focus on renewable energy is insufficient. And protest against the plan is gathering speed. But some may be surprised at who’s helping to lead the way. Many religious leaders are voicing concern about America’s dependence on fossil fuels. The Great Lakes Radio Consortium’s Rebecca Williams has the story:


(natural sound of birds, street sounds, wind)


Twenty minutes before Father Charles Morris will listen to confessions, he’s up on the rectory roof… inspecting his new solar panels and windmill. He’s perched three stories above the ground, so he has a clear view of his neighborhood here in Wyandotte, Michigan. It’s a sunny afternoon. But for as far as he can see, his roof is the only one that’s turning the sunlight into electricity. And he wants to change that.


“Even in a working class, industrial area such as Wyandotte, an inner ring suburb, if it can work here, it can work anywhere. If you would have homes all across the Detroit area, across Michigan, across other communities, that were to adopt this model, I think it would have a profound impact on the stress we’re placing on nonrenewable resources.”


Father Morris’ parish, St. Elizabeth Roman Catholic, is among the first congregations in the U-S to draw energy from the sun and wind. But he’s not alone in his mission to expand the use of clean energy throughout America.


Across the country, religious leaders are writing to Congress, rallying at SUV dealerships, and making their houses of worship more energy efficient.


St. Elizabeth is a winner of the Environmental Protection Agency’s Energy Star award. Four other congregations also won this year’s award, including a Sikh temple in Illinois, and a Lutheran church in Iowa.


This past June, Father Morris was up on his roof, standing above a gathering of 70 people. For those watching, the day held some miracles.


“During the blessing of the solar panels, it was a bright sunny day, no wind, and no wind all morning. But the moment that the prayer had finished for the blessing of the solar panels, and they were switching over to the blessing for the wind generator, and I walked over with the holy water to bless it, this gust of wind comes out of nowhere, and it starts to spin, just as it’s beginning to spin right now (windmill whirs).” “It was incredible, and people were going, ‘ooh, ahh.'”


While using alternative energy sources has immediate benefits at home, leaders such as Father Morris hope that enough people will save energy locally to have a broader impact.
Not only on energy policy but also on energy practices around the globe.


There are 18 Interfaith Global Warming Campaigns in the U.S. Kim Winchell directs the one in Michigan. Her group is concerned that America is ignoring global warming. Electricity generated from fossil fuel releases emissions that add to global warming. So Winchell’s group wants Americans to use less fossil fuel. Muslim, Jewish, and Christian leaders have joined the effort, which Winchell says fits their beliefs.


“All faiths – Christian, Muslim, Jewish – teach that life is sacred, and the created world is given into our keeping by God.”


But should all congregations run on alternative energy?


Critics say that solar and wind energy are not practical for poor or working-class neighborhoods such as the one served by St. Elizabeth because such systems cost thousands of dollars to install. But Father Morris believes in the long-term, the investment is worth it.


“Every dollar you save on energy is a dollar you can feed a hungry person, a dollar you can pay an employee a just wage, a dollar you can do outreach.”


To pay for his hybrid system, Father Morris took a risk – and drew from the parish savings. It may take 12-15 years to see a return on his investment. So he says some churches may hesitate to follow his example.


U-S Representative David Bonior attended the blessing at St. Elizabeth. He thinks the federal government should invest in renewable energy.


“We ought to provide some incentive, not only for churches, but for anybody who institutes energy wise devices. The government has a central role to play in moving us to a more efficient, technologically safer and cleaner environment.”


Some states are already offering incentive programs and grants. But the amount varies, because state energy conservation usually depends on federal funding.


Father Morris just got a grant from the state of Michigan. He used it to put in a solar thermal system to heat water. He’s also inviting schools and churches to tour St. Elizabeth.


“This is the living room; we’ve got the TV on at the moment…” (sounds of football game)


Father Morris lives in the rectory, and his entire first floor runs on solar and wind power. That includes his living room, bedroom, four offices, two computers…and a radio.


“Here’s one of those old fashioned radio/stereos. We’ll have to put the radio on and see what’s on.”


(sound of pop music)


“I don’t know what that stuff is.”


(sound of rapid change between stations)


“You see, this is being powered by solar right now and so the quality of life is the same, there’s no change.”


President Bush’s new energy plan is now being considered by Congress. But whatever the government does, Father Morris says the role for people of faith is clear: to be witnesses for the nation, one windmill at a time.
