Leaders in the solar power industry say the
market is on the brink of expansion. But shortages
of solar panels and electricians to install them
need to be addressed. Many states are seeing those
problems as a way to boost their lagging economies
and create a new sector of manufacturing jobs.
Lisa Ann Pinkerton Reports:


10-year-old Alex Hinkley is sitting at a picnic table watching the Cleveland Indians play
the Kansas City Royals. She’s eating a hotdog, oozing with ketchup, and she’s found
shade under a rather unique awning. It’s made up of 42 solar panels.


The Cleveland Indian’s is the only American League Ball Club to have solar panels and
it’s the only one to use its solar electricity at the park. The panels power 400 TVs at
Jacob’s Field and fifth grader Alex thinks it’s a cool way to introduce people, young and
old, to renewable energy:


“Some people don’t know what they are, but if they know what it is they’ll
wanna learn about it. Because a lot of kids go to the Indians games and I think they should learn a
lot about energy.”


Alex thinks if people are exposed to what solar panels can do, they’ll want them for
themselves. And the notion isn’t far off. High energy prices and state and federal
subsidies are expanding the market more and more each year. In 2006, the electrical solar
industry generated more than 1 billion dollars in revenue.


Exhibiting his products at a Solar Convention, Al Frasz of Ohio Dovetail Solar and Wind
thinks the solar business is on the brink of expansion:


“We’re projecting over 100 percent growth this year. So we’re expecting probably over
the next five years at least 300 percent.”


But the Solar Industry suffers from supply shortages, locally and internationally. Brad
Collins of the American Solar Energy Society says current federal subsidies make solar
competitive with fossil fuels. But entrepreneurs haven’t invested in solar panel factories
because they don’t want their products to collect dust on the shelves if those subsides
aren’t renewed in the future.


So now, he says states are starting to take the lead. He says the rustbelt of America in
particular has a lot to gain from this supply shortage. It’s got the manufacturing
infrastructure and the skilled workforce needed to build the nation’s photo voltaic solar
panels, known in the industry simply as PV. Collins says factories that make auto glass
could easily make the switch:


“There’s a lot of similarities between the production of auto glass and production
processes that could be modified to produce PV. It’s putting a film on a piece of
glass…And that’s the way we can compete.”


Even if states are successful at establishing solar product factories, Bernie Kotlier says
there may not be enough electricians to install the systems. He coordinates weekend
training sessions for the International Brotherhood of Electrical Workers, in Los Angeles:


“What we feel is that the manufacturers are gearing up to supply the equipment but the
next bottleneck will be labor…What would happen if we don’t address it? Well, we’ll have a
shortage.”


In the next ten years, California wants 1 million roofs generating power from the sun.
Kotlier says to make that happen the state will need conservatively, more than 10,000 additional certified
installers than exist today, to make that happen. He says that number’s even bigger is you
look at how the solar market could grow nationally, and across the country certified
installers are already scarce:


“We have people from all around the country who are contacting us regularly saying
we’re getting interest in PV solar in Arizona, in Washington state, in New York, in
Massachusetts. So it is spreading…but it’ll take time. But actually, that’s a good thing because frankly we couldn’t
handle all that interest at once.”


If states continue to offer incentives that bring the cost of solar power down to where it’s
competitive with fossil fuels, Kotlier says solar manufacturing sectors will surely be
required to meet the demand. Where those manufacturing jobs are located and if there
will be enough certified installers nationally remains to be seen. But he says the states that offer
subsides and the people who invest in solar now, could see a huge return on their
investments. Those who delay could find themselves left behind.

Wind Energy Sweeping Away Wildlife?

Wind energy is one of the fastest growing sources of new electricity in the United States. For some environmentalists, that’s
good news. Wind turbines don’t spew smoke into the air. There’s no nuclear by-product. But there is an environmental risk. To see it, you have to view the wind turbines through the eyes of a bird.

Wind energy is one of the fastest growing sources of new electricity in the United States.
For some environmentalists, that’s good news. Wind turbines don’t spew smoke into the
air. There’s no nuclear byproduct. But there is an environmental risk. To see it, you
have to view the wind turbines through the eyes of a bird. The GLRC’s Dustin Dwyer
has more:


Chandler Robbins has spent a lot of time studying how birds kill themselves. He says he
would go out on windy nights to the Washington Monument in Washington, D.C. He’d
stand at the bottom of the 555 foot tall obelisk and watch the birds at the top:


“Just as they get to the tower, they just go around the edge of it and bang, the turbulence
from the winds going around the tower, sweeps those birds against the tower, and they’re
killed.”


Speaking at a conference, Robbins tells the crowd he once watched more than 500 birds
slam into the monument in one night, and that monument is standing still. Now imagine
wind turbines, some of them about as tall as the Washington Monument, with spinning
blades that reach nearly a football field in diameter.


Alex Hoar is with the U.S. Fish and Wildlife Service. He says a single turbine can now
change air currents for three acres around the turbine itself:


“So, if you put up a hundred turbines, the blades are sweeping 300 acres. So, that’s a large
space. And what we don’t know is when are birds and bats at risk.”


We don’t know because no one has really studied it. Both Alex Hoar and Chandler
Robbins say scientists know a lot about where birds take off and where they land. They
know about migration patterns, but they don’t know about what birds do, or where they
go while they’re in the air.


So, with more wind farms being built across the country, it’s not clear what affect they
might have on bird populations, but some suspect it won’t be good. Peter Kailing works
with an environmental consulting company. He recently did an environmental impact
study for a new 47 hundred acre commercial wind farm in Michigan. He says scientists
can learn a lot from the wind farms that have already been built. He says the ones that
have done the most damage to wildlife have a few things in common:


“The turbine was in a narrow valley, or a mountain-pass, or on the edge of a large
water body with steep wooded cover that was used by migrating songbirds, there’s almost
always a topographical association.”


Weather also plays a role. Peter Kailing and others say that birds tend to avoid cloud
banks by flying under them. That could put them in the path of turbine blades. So, one
way to limit damage would be to shut the turbines down on cloudy days.


Chandler Robbins says better technology could also limit damage. He says turbine blades
could be equipped with sensors:


“If a bird or a bat collided with that blade, it would set up enough vibration so that the
blade could be feathered temporarily to avoid other birds striking until the immediate
problem is over.”


Feathering essentially means that you twist the angle of the blade so that wind passes
over it, rather than pushing the blade into a spin. That way, birds aren’t sucked into it.
It’s basically the turbine’s braking system. Some say you don’t even need a sensor on the
turbine. They say engineers could monitor radar and thermal imaging. That would tell
them if any migrating birds are in the area, and if they are, feather the blades.


Of course, the absolute safest solution in the short term might be just to stop building
wind farms, but you’d be hard-pressed to find anyone who thinks that’s a good idea.
Most seem to realize that any way of making electricity will have some impact on the
environment. The question is what can be done with each of them to minimize the risk.
With wind energy, that work is just getting started.

Wind energy is among the fastest growing sources of new electricity generation. Now,
scientists are looking at ways to make wind turbines safer for birds and bats. The
GLRC’s Dustin Dwyer has more:


A study published last year by the Government Accountability Office says wind farms
have had little impact so far on birds and bats, but the study says that could change as
more wind farms go up. The question is how to minimize the risk.


Alex Hoar is with the U.S. Fish and Wildlife Service:


“Not all turbines cause a problem. There are turbines around that had bird
problems. There are lots of turbines that don’t. And we’re trying to learn why.”


Hoar says scientists know a lot about migration patterns for both birds and bats. But they
haven’t tracked the animals’ behavior while they’re in the air. Scientists are now using
thermal imaging and radar to study flight patterns in detail, and Bowling Green State
University in Ohio recently won a one million dollar grant to study the impact of smaller
turbines on wildlife.

Winter Cyclists Woo New Recruits

There are some people so determined to fight pollution and traffic congestion that they bike instead. There are even some brave souls who bike year-round, come good weather or bad. The Great Lakes Radio Consortium’s Shawn Allee meets one woman who wants to join them:

There are some people so determined to fight pollution and traffic
congestion that they bike instead. There are even some brave souls who
bike year-round, come good weather or bad. The Great Lakes Radio
Consortium’s Shawn Allee meets one woman who wants to join them:


For a lot of people, transportation’s more than just a way of getting from
point A to point B. They take it personally. They want to cut air
pollution, use less energy, or they want to save money on commuting.


For those kinds of reasons Julie Lenfest doesn’t own a car. For years, she
relied on buses, but she hated them. They ran late. They didn’t go
everywhere. She was fed up, so she tried biking.


“I hate to beat down on the buses, but I got really frustrated with the
buses and it made me want a car, and then having a bike made me not want a car
anymore … it took that whole frustration away.”


For a while, each ride was a kind of … personal triumph.


That was fine while she lived in California, but Julie’s routine hit a snag
after she moved to Chicago. She was used to mild, Californian winters,
not blustery, frigid Midwestern winters. Sometimes the cold here gets so
bad it brings tears to your eyes. No wonder Julie chickened out last
winter. She stayed off her bike and hopped the bus instead.


“I don’t know, just, ah, talked myself out of it, but we’ll see. Now, I need
adventure.”


Julie started thinking about winter biking weeks before there was any
snow. She needed advice. So, she came to a seminar on how to prep
herself and her bike for winter. She’s come to the right place.


“I’m Alex Wilson. This is my shop, West Town Bikes … (continue)”


If anyone’s capable of teaching Julie and the other folks here, Alex is.
He’s more than just a winter biker and expert repairman. He’s a bike
evangelist.


“I just can’t find any inherent bad in bikes. Plus, bikes are fun, you know.
What better reason to be interested in bikes than, bikes are a lot of fun?”


Alex starts the class with how to keep warm. The trick’s not to get too
warm, otherwise you get drenched in sweat. Layering’s good, but
there’re no hard and fast rules about which long underwear goes with
what rain gear. Alex says trial-and-error works best.


Then there’s safety. Alex suggests putting reflective tape on your bike as
well as your jacket.


“Motorists are not looking for cyclists in the winter, so you need to be
seen.”


The next lesson’s about street salt. Salt corrodes your bike and can make
it hard to peddle.


“After after you’ve gotten to your destination, do this:”


(Sound of a bang)


“Bounce your bike hard and knock off all the stuff that’s built up on your
bike.”


Alex says all this mechanical advice is important but misses the point.


“The biggest thing that holds people back from biking in the winter is not
any gear or special equipment. It’s having the will to do it or having the
courage to do it.”


And there’re plenty of things to be scared of. Everything from being seen
in geeky winter outfits to more serious stuff, such as frostbite, but Julie’s
encouraged and she peddles out of the seminar, with her resolve intact.


(Sound of bike wheel)


A month later, I meet Julie to see whether her determination was a match
for the weather. Today, she’s biked to an outdoor ice rink. Snow’s
heaped along the sidewalks and we can see our breath. While she laces
her skates, she tells me the good news first. Turns out, she hasn’t been
alone.


“There are other people winter biking, I thought I’d be the only person.”


These strangers offered useful tips on clothes and safe routes.


There have been problems, though. Early on, Julie was looking for
adventure, but she changed her tune after the season’s first major storm.


“There was snow and it was slippery and they hadn’t put salt down yet.
So I decided I would walk on the sidewalk because I didn’t trust my
brakes and I didn’t trust other people’s brakes.”


That day sapped the fun out of winter biking, but she realized something
else. She’s kind of over the thrill. She’ll keep biking, but more and more,
it’s just the way she gets around. She doesn’t have to prove anything to
her friends.


“They just don’t understand how you can live without having a car, and
I’m just tired of explaining it to them over and over. So, I just say I can be
there at this time and I don’t tell them how I’m getting there; it’s my
business.”


So, she doesn’t talk about it so much anymore. It’s good to cut down on traffic or
save energy, but winter biking’s not so easy. If she chooses to keep it at, it’ll
be because she enjoys it, not because someone’s convinced her she has to. That’s
to say, it’s personal, and, to her, important.
