President Barack Obama’s visit
to Nellis Air Force Base near
Las Vegas has more to do with
what’s on the ground than it
does the fighter jets in the air.
Lester Graham reports on the base’s
solar energy project:

Nellis Air Force Base is home to the nation’s largest solar photovoltaic power plant. The system generates enough electricity to power the equivelent of more than 13,000 homes.

The Air Force’s partner in the solar plant is MMA Renewable Ventures. Matt Cheney is CEO.

Cheney says there are lots of advantages, starting with no need for foreign or domestic fossil fuels that emit greenhouse gases.

“It gets its energy from the sun. And, by the way, the sun is pretty predictable and effectively the energy we get from it is free.”

That’s not to say solar energy is free. The array at Nellis Air Force Base cost 100-million dollars to build.

The Air Force saves about a million dollars a year. So, it’s going to take a while to break even.

But as the demand for more solar goes up, the technology gets cheaper, in just a few years you might be able to get solar energy for about the same price as from coal-burning power plants.

Solar Shortages

Leaders in the solar power industry say the

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.

Straining Water Supplies in the Southwest

  • Nancy and Dave Tom bought this home near Apache Junction, Arizona. They have to haul all the water they use with their pickup truck, so they quickly learned how to conserve. (Photo by Mark Brush)

Many areas in the Southwest are booming. With all this new

a look at the lengths people go to, to get water in the desert:

Transcript

Many areas in the Southwest are booming. With all this new
development, pressures on water supplies are growing. Mark Brush takes
a look at the lengths people go to, to get water in the desert:


Nancy and Dave Tom used to get their water from a city water supply.
That was back when they owned a home in Tempe, Arizona. Like a lot of
people in the area, they had a pool, plants that needed water year
round, and a green lawn out back. Not exactly a desert scene. It took
a lot of water to support their lifestyle.


But life in Tempe was getting crowded. And when somebody rang their
doorbell and offered to buy their house for almost twice what they paid for
it, they jumped at the chance to move to a smaller town.


(Sound of birds)


They found a house for sale just outside of Apache Junction. It’s a
small city in the desert about an hour’s drive from Phoenix. The house
is at the foot of a dry mountain range and has spectacular views. But
the house didn’t have city water service:


“When we saw this piece of property we pretty much fell in love with it
immediately. And it was stated in the multiple listings that you did
have to haul water. And that the water trailer conveyed with the
property (laughs).”


(Sound of hooking up the truck)


To get their water, Dave Tom hooks up a trailer with a big plastic
water tank. He tows the trailer about 4 miles into Apache Junction.
There’s a water filling station here. He gets about 90 gallons of
water for each quarter dropped into the machine:


(Sound of truck parking)


“I’ve got my four quarters here – we’re going to put it in the vending
machine and have at it.”


(Sound of quarter and water rushing)


He makes about two trips a week, so he figures they’re using about 600
gallons of water a week. That’s quite a bit less than the 6000 gallons
they were using in Tempe.


Some of the things they did to cut back were obvious. Since they no
longer had a pool – and they didn’t water a green lawn – that helped.
But in their new place, they also bought a high efficiency washer and
dishwasher. And, when they don’t have guests around, they cut down on
the number of times they flush the toilet.


And they’re not alone in trying to cut back on water use. Even their
neighbors who have a well are really careful with their water. Phil
Reinhart lives just up the road. He’s rigged up a system of gutters
and pipes to catch rain water:


“You see it drains the front of my house and it comes down these
gutters into these storage barrels. And then I have a little pump that
I use and a little twelve volt battery that I use to pump my washing
machine full and then my washing machine then discharges into my citrus
trees – this is a lemon – here, take a lemon back with you.”


Reinhart is careful with his water. And he’s worried that the
population boom will put a strain on his well.


(Sound of water)


The tank on David Tom’s trailer is full. He tries to shut the water
off:


“Alright we’ll push the shutoff button – and watch out, you’re going to
get wet… no the shutoff isn’t working. We’re going to dump 25 to 30, maybe 40,
gallons of water, which to me it’s a shame they need to come down and
fix this.”


(Sound of water flowing)


A lot of this water spilling onto the ground has traveled a long way to
get here. The Central Arizona Project pumps water from the Colorado
River 230 miles away.


“Rather than a river than runs downhill by gravity, we’re a river that
runs uphill by pumps. We’re the largest electric consumer in the state
of Arizona.”


Sid Wilson is the general manager of the Central Arizona Project. He
says most of the water pumped into this region is used for farming.
But with rapid development, that’s expected to change. More water will
be used to service the new homes sprawling out into the desert.


“The CAP right now provides 40% of the water to this area, 40%, and that will increase
some over time.”


Wilson says people are going to continue to move to the Southwest. So,
future water supplies will have to be developed.


Back at their home near Apache Junction, Dave Tom has finished filling
up their underground storage tank. It’s taken him two trips with the
trailer.


(Sound of gurgling)


His wife Nancy says their new home has changed the way they think:


“Life out here in the desert has given me a greater appreciation for
water. There’s a part of me that says this is how everybody should
live in the desert. That they should have that awareness of their
water usage and embrace the fact that you live in the desert rather
than trying to change it into a lush tropical paradise.”

States Slow to Pump Up Ethanol

  • As the price of gasoline rises, many states are looking for alternatives. One of those alternatives is the ethanol blend, E-85. But, some states (like Ohio) are not keeping up with the trend. (Photo by Lester Graham)

The federal government is focusing new attention on research and development of ethanol. Some states – especially those in the corn belt – are getting into the act too. The GLRCs Karen Kasler reports:

Transcript

The federal government is focusing new attention on research and
development of ethanol. Some states – especially those in the corn belt –
are getting into the act too. The GLRC’s Karen Kasler reports:


Now that gasoline is near or above three dollars a gallon, ethanol seems
to be everywhere. The Renewable Fuels Association says more than a
third of the gasoline in the U.S is blended with ethanol, an alcohol based
fuel made with the sugar found in corn and other grains. A 10 percent
ethanol/gasoline blend can be used in every vehicle on the road, but
many politicians and consumers are very interested in the 85 percent
ethanol blend – E-85 – as an alternative fuel for cars and trucks. But
getting E-85 to drivers who have cars which can use it isn’t that easy.


Tadd Nicholson with the Ohio Corn Growers Association, says part of
the problem is the big oil companies have banned E-85 pumps under the
canopies at branded stations.


“Oil companies don’t own ethanol production. They own oil refining,
and so that’s their profit center and that’s where they get their fuel and so
they have a lot of control over that. They don’t own ethanol. I don’t
know why. They should, but they aren’t in the ethanol ownership
business yet. I say ‘yet’.”


The governors of Wisconsin and Minnesota have asked the big oil
companies to change their E-85 policy, and some states have been
encouraging independent gasoline dealers to put in E-85 pumps for a few
years.


But others, such as Ohio, have been lagging behind in the trend. Only
recently has Ohio launched a new energy action plan that sounds
ambitious, when it comes to providing access to ethanol to drivers.


LeeAnn Mizer is with the Ohio Department of Agriculture.


“The goal is to triple the amount of E-85 pumps available to Ohio
consumers by the end of 2006.”


That sounds like a lot – but it’s not, says Dwayne Seikman heads up the
Ohio Corn Growers Association.


“Tripling’s a nice start. There’s six… that would go to 18. But with over
150,000 vehicles in the state of Ohio, that’s not enough to cover the
effort.”


Since corn is Ohio’s top crop… it would seem to make sense. But unlike
other states in the corn belt, there are no ethanol plants in operation in
Ohio, though there are at least three under construction, and ethanol
supporters say the state is way behind its neighbors when it comes to
getting ethanol pumps at service stations.


Sam Spofforth is executive director of Clean Fuels Ohio.


“I’ll be honest, we’d like to see a lot more and we think a lot more is
certainly very possible. Indiana, they’re up to about 25 to 30 stations.
Illinois has over a hundred. Minnesota has almost 200 at this point.
Even places like Arizona are putting in E-85. They don’t make any corn
in Arizona. We think Ohio can do a lot more.”


Some critical studies have found that ethanol has a high energy cost with
low benefits – ethanol supporters say that’s been debunked. Whether
ethanol makes economic or ecological sense or not is still not certain.
But one thing is certain – cars using ethanol blends need to fill up more
than those using regular unleaded gasoline.


Robert White with the National Ethanol Vehicle Coalition says that’s
offset because typically ethanol-blended fuels cost less than regular
unleaded gas.


“Well, no doubt the fuel economy is the only negative with E-85, and we
tell folks that is where the price differential hopefully is there to make
E-85 use a wash.”


Part of the reason the price is lower is because the ethanol industry is
heavily subsidized by the government. Those lower costs would quickly
disappear if the subsidies were removed. Because ethanol is cleaner
burning, many support further development and use of the renewable
fuel.


General Motors is increasing the number of vehicles it produces that can
burn ethanol. Ford already produces E-85 burning cars and trucks.
However, many believe for ethanol production to be truly efficient,
farmers will have to start growing crops such as switch grass for ethanol
because corn requires too much fossil fuel based fertilizer and other
inputs to make it a permanent solution.

Nuke Plant Leaks Revealed

The nuclear industry is dealing with criticism over spills of a chemical called tritium. The GLRC’s Shawn Allee reports:

The nuclear industry is dealing with criticism over spills of a chemical
called tritium. The GLRC’s Shawn Allee reports:


Federal regulators don’t require nuclear power plants to report what’s
considered minor tritium spills to the public. That’s despite the fact
tritium can make water radioactive, but some residents in Arizona,
Illinois and New York are furious. They’ve learned about tritium
spills… sometimes years later. Now, power plants want to change
course.


The Nuclear Energy Institute’s Ralph Andersen says the industry will
report even minor tritium leaks to the public.


“It’s appreciating the common sense issue that of course, neighbors
around a nuclear power plant want to be aware of emissions from the
plant, not just hear about it later or read about it in the paper.”


Federal regulators insist the public’s safe. Nuclear watchdog groups
remain worried, though. The agreement covers only nuclear plant
operators, not places that store tritium outside power stations.

Ten Threats: Southwest After Great Lakes Water?

  • This billboard was displayed along several major highways in Michigan. The sponsors were hoping to raise awareness about water diversion, but do these arid states really pose a threat to the Great Lakes? (Photo courtesy of Central Michigan Life )

Transcript

We’re continuing our series on the Great Lakes. One of the Ten Threats
to the Great Lakes that experts identified was water withdrawals. Our
guide in this series, Lester Graham, says the next report looks at one of
the myths of water withdrawals.

Environmentalists and policy makers say a thirsty world could pose a
major threat to the Great Lakes. Water wars have been predicted in arid
parts of the globe, and some say the laws of supply and demand might
one-day lead to a raid on the region’s fresh water. Reporter Mark Brush takes a
closer look at one claim: that states in the southwest will one day come
after the Great Lakes water… and finds that it might just be H2O hype…


Taking water out of the Great Lakes is a hot button issue, and no one is
more aware of this than politicians looking for votes. In the 2004
campaign, President Bush used the issue to rally a crowd in Traverse
City, Michigan:


“My position is clear. We are never going to allow the diversion of
Great Lakes water.”


(Sound of applause)


The issue taps into people’s emotions. People get outraged when they think
of someone taking water out of the Lakes – especially when they’ve seen lake
levels dropping over the years, and the region’s political leaders have listened
to those concerns. The states and provinces that surround the world’s largest fresh
water system are working on a compact that will prevent water diversions.


But where is the threat to Great Lakes water coming from? We
conducted an informal poll on the streets of Ann Arbor, and we asked
people: “who wants water from the Great Lakes?” Six out of the ten
people we talked to pointed to the west:


(Sound of street)


“Las Vegas, the Southwest.”


“Probably the dry states in the West. Arizona, Nevada.”


“I think the west should keep their damn hands off our water.”


But do the arid states in the West really pose a threat to Great Lakes
water? It turns out – this same question was asked more than twenty
years ago.


In the 1980s, the U.S. Army Corps of Engineers studied the possibility of
moving Lake Superior water to the Missouri River. It’s a distance of
about six hundred miles. Farmers in the High Plains states were hoping
to use this water to irrigate their crops.


Jonathan Bulkley is a professor of civil and environmental engineering at
the University of Michigan. Bulkley and his colleagues analyzed this
diversion plan, and he says the whole project would have been too
expensive:


“We found it would take seven 1000 megawatt power plants dedicated to
lifting the water, because water needs to be lifted to reach these distant
locations, and in addition there would have to be conveyance structures
built to transport the water, and our conclusion was the total cost would
far exceed the value of the water.”


In other words, Bulkley found that it would be cheaper for these states to
find other sources of water – or to find ways to conserve the water they
had left, and this was a diversion of only 600 miles. A diversion all the
way to the Southwest would mean piping the water almost twice that
distance.


“We are always looking for extra water – everyone in the Southwest is
looking for extra water.”


Bob Barrett is a spokesperson for the Central Arizona Project. It’s one of
the biggest water suppliers in the Southwest. The Project pulls water
from the Colorado River and delivers it to southern Arizona. Barrett
says he can’t imagine a situation where Great Lakes water is pumped for
more than a thousand miles to the Colorado River:


“Most people don’t realize it, but a gallon of water weighs about eight
pounds, and if you’re going to push that up and over the Rocky
Mountains you’re going to need a lot of power. (Laughs) So, it’s a good
idea, but I don’t see how anybody could pay for it.”


But some observers say even though it might not happen today – it could
happen in the future. They point to a fast-growing population and a fast-
dwindling fresh water supply in the southwest. They say that
combination could drive engineers and policy makers to devise a way to
get Great Lakes water.


But Barrett says for states like Arizona, California, and even Texas – it
would be cheaper for them to build desalinization plants… these plants
convert ocean water into drinking water:


“I mean why should Texas build for a canal and then have to maintain it
from the Great Lakes down to the state of Texas when they can go to the
Gulf Coast and build several desalinization plants, and then just pipe it
wherever they need it?”


So, a large-scale water diversion to the southwest seems unlikely.
Experts say water from the Great Lakes is much more likely to go to
cities and towns right on the edge of the basin, but as legislators move to
tighten restrictions on diversions – even these places will
have a hard time getting access to the water.

Thirsty City Waits for Water Diversion Law

  • Diversion of water from the Great Lakes is a controversial issue. Many worry that diversion could affect life in the ecosystem. Others worry about obtaining sources of fresh water for drinking. (Photo by Brandon Bankston)

Great Lakes governors and their counterparts in Canada are working on a legal agreement called Annex 2001. The document will determine how water from the Great Lakes will be used and who gets to use it. Controversy has already erupted over the possibility of one city’s bid for the water. The city is looking toward the completed Annex for guidance. The Great Lakes Radio Consortium’s Christina Shockley reports:

Great Lakes governors and their counterparts in Canada are working
on a legal agreement called Annex 2001. The document will determine how
water from the Great Lakes will be used and who gets to use it. Controversy
has already erupted over the possibility of one city’s bid for the water.
The city is looking toward the completed Annex for guidance. The Great
Lakes Radio Consortium’s Christina Shockley reports:


Dan Duchniak says he’s an environmentalist.


“We have the low-flow showerheads in our house, we have the low-flow faucets, we have the high-efficiency washers and dryers, our kids know about those, you know, they think they’re fun.”


But Duchniak is in the middle of a bitter fight with other environmentalists and officials over his area’s largest natural resource: water from Lake Michigan. Duchniak is the water manager for the City of Waukesha, Wisconsin. It’s just west of Milwaukee. Waukesha is only about 20 miles from the Lake Michigan shore. Right now, Waukesha gets its water from wells that tap an aquifer deep within the ground. But Duchniak says the wells won’t sustain the long-term needs of the city.


“As the water levels drop, the water quality degrades, and what happens is we’ve seen an increase in different water quality parameters, one of those being radium.”


And radium is a health problem. In very high doses, radium can cause bone cancer. To solve its water problems, the City of Waukesha might ask for access to Lake Michigan water. But even though the community considers the lake part of its back yard, there’s a major problem. Even though it’s close, Waukesha sits outside the Great Lakes basin.


That means the area’s ditches and streams drain away from the lake. Rain water runoff and treated water from the sewer system flow toward the Mississippi River Basin. The governors and premiers might include a rule in the Annex 2001 that says communities sitting outside the Great Lakes basin must return treated water to the lake, if they use it.


Engineers who study water in the area say Waukesha could make the case that the city is already using Great Lakes water. That’s because the city’s wells tap into water beneath the surface that supply water to Lake Michigan. But environmentalists say that argument isn’t going to fly. Derek Sheer is with the environmental group “Clean Wisconsin.” He says Waukesha would be pumping a lot more water directly from the lake than the underground aquifer would replace.


“They’re not returning 13 million gallons of water back to the Great Lakes by any stretch of the imagination.”


But the city of Waukesha knows that if the finalized Annex 2001 looks anything like the early drafts, the city would have to return most of the water it uses back to the lake. Waukesha’s water manager, Dan Duchniak says that could be done in a combination of ways. The city could pump it back to the lake, pump it to a nearby stream that flows to the lake, or stop using the ground water completely and let it flow back to the lake.


People on both sides of the water issue seem to agree on one thing: because of the huge amount of water in the Great Lakes system, and its natural ebb and flow, the amount of water the City of Waukesha would take would not harm the Great Lakes’ ecosystem. Even if it’s not pumped back.


Art Brooks is a professor at the Center for Great Lakes Studies at the University of Wisconsin-Milwaukee.


“The amount of water they intend to withdraw would probably lower the level of Lake Michigan on the order of a millimeter or so, probably less that five millimeters per year.”


But it’s not just Waukesha that has environmentalists worried. Professor Brooks and environmentalist Derek Sheer say if Waukesha gains access to Great Lakes water, it could set a dangerous precedent. Sheer doesn’t want other states and countries to start withdrawing Great Lakes water.


“If Waukesha and Arizona and Georgia and all these other places start pumping large amounts of water out of the basin, we could see a dramatic lowering of the water in the lakes.”


The city of Waukesha says it needs the water and would abide by whatever the Annex 2001 agreement sets down. And Waukesha’s water manager, Dan Duchniak, says that includes what it determines about return flow. He says arguing about the issue right now is a waste of time, since the Annex isn’t done. Beyond that, Duchniak says Waukesha is part of the Great Lakes system, and is not about to suck the lakes dry.


“Lake Michigan is in our back yard. We can see Lake Michigan from here. We’re not that far away from it.”


The experts say Waukesha would only be the first in line to ask for Great Lakes water. With suburbs sprawling away from the big cities on the lakes more and more towns will be eyeing the Great Lakes when demand for water exceeds their underground supplies.


A draft of the Annex could be ready this year, but it will most likely go through a lengthy series of votes before it becomes law.
