Energy prices are rising, and people are looking
for ways to conserve power. But some rate payers are
saving money without actually cutting their energy use.
Instead they’re changing when they use power. Samara
Freemark reports:

It’s Saturday morning, and Ellen and Peter Funk are doing laundry.

The Funks used to do chores when most people do – they would get home from work and
switch on their dishwasher, dryer, and computer. They never really paid attention to
what that meant for their electricity bill.

“I never thought about electricity before. Never, never, never. Except when I got the bill.
But, you didn’t have any control. Because you paid the same price whether you used it at 2 in
the morning or 2 in the afternoon.”

But a couple of years ago the Funks started paying for their electricity differently than the
rest of us. They live in one of only a handful of buildings in New York City that
participate in a Real Time Pricing program.

Real Time Pricing charges consumers a different rate depending on when they use power.

The Funks know that running their dishwasher or turning on a light will cost more at 5
pm than at 10 pm. That’s because they get a color-coded chart every month that breaks
down their energy prices by time block.

“The green here is low. And the green starts at 10 o’clock at night and goes through 1
o’clock the following afternoon. The yellow is medium from 2 to 5 every day. And then
Monday to Friday there’s a high period from 5 to 9. That means stop. I think that’s why
they used red.”

It’s the same concept that makes cell phone minutes cost more during the day. Power
costs more when more people want to use it.

Real Time Pricing can save consumers a lot of money. Peter Funk says his family saves
hundreds of dollars a year by just shifting when they use energy.

“It’s an ongoing savings. We do these things because they make sense economically. We
don’t do it because we’re virtuous, we don’t do it because we’re better than our neighbor.
We just, this is the way we buy electricity because it makes sense.”

Real Time Pricing programs shift around power demand, so fewer people use energy
during peak hours. A Department of Energy study earlier this year estimated that Real
Time Pricing programs could cut peak energy use by about 15%.

That could actually help regions improve air quality and conserve resources by
decommissioning old, polluting power plants. Here’s how.

Most areas have a network of power plants. Usually only a few of those plants – the
newest, cleanest ones – are in use. But when energy demand peaks, the older, less
efficient plants kick in. And those plants spew a lot of carbon dioxide and other
pollutants into the air.

“It’s really not the number of power of power plants, but the ones you have to turn on at
critical times.”

Jim Genarro is a New York City councilman. He also chairs the council’s Committee on
Environmental Protection.

He says the plants that kick in when demand peaks are the worst in the system.

“We have a lot of reserve capacity in the city, but these are the older, dirtier plants, and
when you run those at peak capacity, it really means a lot of pollution.”

And Genarro says those plants cost even when they’re not producing energy. The city
has to maintain them all the time so they can switch on when needed. That wastes energy
and resources. It also means there are power plants that are only used a few weeks, or
even days, a year.

If power companies could cut peak energy demand, rarely-used, polluting plants could
become totally unnecessary. And many could be shut down.

Food to Fuel Drives Wheat Prices

Short supply and high demand for wheat means
prices are at record levels, and rising. But the high
cost of wheat is bad news for people who buy it. And

Short supply and high demand for wheat means
prices are at record levels, and rising. But the high
cost of wheat is bad news for people who buy it. And
in North America, where most people’s diets are based
on wheat, that means just about everyone. Sarah Hulett
has this look at what’s behind the run-up in prices:

Jackie Victor is sitting on a stack of 50-pound bags of organic wheat flour inside the
bakery she co-owns. And these days, it’s a pretty expensive seat.

Victor says in the last year, what she pays for those bags of flour has doubled.

“So it’s a very scary time, and I don’t think just – really for the industry, although it is
scary for us – it should be a warning sign for the country that something here is amiss.”

In the fall, Victor raised her retail prices at Avalon International Breads in Detroit.

So a loaf of bread that comes out of this batch getting mixed by baker Kevin Boyer will
cost you 50 to 75 cents more today.

“This is the multigrain bread. This is our Motown Multigrain.”

Soon, one of those loaves will probably cost even more, because the price of flour keeps going up.

(forklift sound)

Avalon Bakery buys its flour from Dawn Food Products. Inside one of its central
warehouses, forklift operators move pallets of baking ingredients into tractor-trailors. It smells like a kitchen pantry. And that’s basically what this is: a gigantic
pantry full of baking ingredients that will be shipped all over the world.

Miles Jones points out a pallet full of wheat gluten, which is used in most commercially-produced baked goods.

“That’s vital wheat gluten there. The price of that vital wheat gluten, just as an example,
has about tripled here in the last six months.”

Jones is co-chairman of the board at Dawn Foods. He’s been in the baking industry for close to four decades, and he says he’s never seen prices so high.

There are several reasons for the spike in wheat prices. Drought and other bad weather
wiped out a lot of the global wheat crop over the past two years. And fast-developing countries like China
and India are consuming more food made from wheat.

And then there’s the ethanol factor. More farmers are planting corn to sell to ethanol
refineries. Jones says that’s gobbling up land that used to be planted with wheat and other
crops. And he says it’s put us on a dangerous path.

“The end results are in the paper every day. You can see the skyrocketing food prices. And when you start trading food for energy, that’s not a good trade long-term.”

With wheat prices at record levels, more farmers might decide to plant it this year. That would boost supply and bring prices down.

Bruce Babcock is an economist, and he heads the center for Agricultural and Rural Development at Iowa State University. He says the test for that theory will be the amount of spring wheat that gets planted in April and May.

“The problem of course, for farmers, it’s not really a problem, it’s a great thing for farmers, is that they can pick wheat or soybeans or canola or any crop and the price is out of this world. So because the price of everything else is up so high, I don’t think we’ll see wheat increase as much as we would hope.”

Babcock says there is some good news on the global supply front. Australia and Argentina are expected to harvest a normal amount of wheat this year. Those are two major wheat producers that had a couple of years of terrible crops.

A big question will be whether farmers in the US and Canada will get the kind of weather they need and a bumper wheat crop this year.

Treated sewage water has been used to water
lawns and flush toilets before. But now the world’s
largest “toilet-to-tap” system has gone online. Mark
Brush reports on the new water treatment system:

You think flush the toilet and it’s gone, right?

Well… that’s not happening in the O.C.

In Orange County California, the water people flush from their homes and businesses will
eventually come back to their taps.

The treated sewage water is sent to a water purification plant. It’s treated some more and
then pumped back into the aquifers where the county gets its water supply.

Mike Wehner is with the Orange County Water District. He says, at first, people kind of
held their nose at the idea:

“The biggest concern is kind of a general yuck-factor. It’s just, ‘You mean sewage? We’re
not going to drink that.’ But after people develop an understanding of the kind of
treatment processes we’re talking about, the yuck-factor diminishes, it goes away.”

Wehner says when the half billion dollar system is at its peak; it will add 70 million
gallons of recycled water a day to the areas drinking water supply.

Tribe Sues for Fishing Rights

The Ottawa tribe of Oklahoma has filed suit in federal court,
claiming it still owns fishing rights in Lake Erie, but that’s
prompting natural resources officials to worry about the prospect of
over-fishing in the lake. The Great Lakes Radio Consortium’s Bill
Cohen reports.


Members of the Ottawa tribe say a 200-year-old treaty gave them fishing
rights, but Ohio officials who regulate fishing are hoping the tribe
doesn’t win its lawsuit.


They say, since the tribe is a sovereign nation,
the Native Americans would not have to abide by state limits on fish
catches, and that could ruin the business of the commercial fishing
companies that rely on the lake.


The Ottawa’s lawyer, Dick Rogovin, says the state could compensate.


“If these tribes take a lot of fish out of the water, I think the state’s
got to put fish back in. That’s their obligation: to supply fish for
everybody else.”


Some Native American tribes do have fishing rights in other parts of the
Great Lakes, but court agreements between the tribes and the states put
limits on the catch of fish in those areas.

The Department of Defense will re-open the case of 1400 mystery barrels secretly dumped into Lake Superior during the Cold War. The barrels were dumped in an area where the Red Cliff Band of Chippewa Indians have territorial rights. The DoD now has an agreement with the Red Cliff Tribe to investigate the weapons dump site. The Great Lakes Radio Consortium’s Mike Simonson has this report:


Documents show barrels of weapons scraps manufactured by Honeywell from 1958 to 1962 were secretly dumped by the U.S. Army Corp of Engineers a few miles east of the Duluth-Superior harbor.


Red Cliff Environmental Consultant Dave Anderson believes there is an imminent danger to Duluth’s water supply. The barrels are rusting away 100 to 300 feet deep near the city’s water intake. He says he’s found evidence of PCB’s and unidentified ash.


“Right now we know that there is more to these barrels than what has been disclosed in the past. That the barrels are not just scrap steel grenade parts. There are other wastes that are hazardous that are contained in the barrels and we now know that the barrels are leaking some of those substances.”


The DoD has awarded the Red Cliff Tribe a 105-thousand dollar grant to assess and further investigate this 20 mile square site and report the findings in October for possible clean-up.

Transcript

The U.S. House and Senate recently passed a bill that will help keep Asian carp out of the Great Lakes. As the Great Lakes Radio Consortium Celeste Headlee reports, the federal government will contribute nearly two and a half million dollars to help repel the fish:


Asian carp are huge, often growing to be four feet long and weighing 80 pounds. They are also extremely prolific and voracious. Most Asian carp consume up to 40 percent of their body weight every day. There is currently an electric fish barrier strung across the bottom of the Chicago Sanitary and Ship Canal to keep the fish out of the Great Lakes. The barrier creates an underwater field of electricity that repels the carp.


Andy Buchsbaum is the director of the National Wildlife Federation’s Great Lakes Office. He says the current barrier is temporary and due to fail next year.


“Today the Great Lakes really dodged a bullet. Right now, the carp are poised 20 miles away from the failing barrier, which is just downstream from Lake Michigan. And if that barrier fails, then essentially the Great Lakes as we know them are over.”


The U.S. House and Senate passed a bill that will supply 75 percent of the funds for building a new barrier. The Great Lakes governors have agreed to supply the rest of the money. President Bush has said he will sign the bill when it reaches his desk. Buchsbaum says the new barrier can be completed within 60 to 90 days.

Glassing Bottled Water’s Image

Over the past ten years, sales of bottled water have tripled. There’s a huge thirst for water that’s pure, clean and conveniently packaged.

Over the past ten years, sales of bottled water have tripled. There’s
a huge thirst for water that’s pure, clean and conveniently packaged.
As part of the ongoing series, “Your Choice, Your Planet,” the Great
Lakes Radio Consortium’s Victoria Fenner takes a look at why we’re
turning to bottled water and whether it’s worth the price:


On a warm sunny day, it’s easy to believe that sales of bottled water
are skyrocketing. People everywhere in this waterfront park in
Toronto are carrying plastic water bottles labeled with pictures of
glaciers and mountains. With a price tag of anywhere from fifty
cents to over a dollar a bottle, that’s a lot of profit flowing to
the companies that sell it.


But Catherine Crockett and Colin Hinz are packing water the old-
fashioned way. They don’t buy bottled water. Instead, they fill up
their own bottle before they leave home and refill it at the drinking
fountain.


Crockett: “Well, it’s cheaper and as an environmentalist, I’d rather
refill a container than waste a lot of money on pre-filled stuff that
isn’t necessarily any better than Toronto tap water. What’s the
point in paying a dollar for a disposable bottle full of what’s
probably filtered tap water anyway?”


Hinz: “Personally I think a lot of what’s behind bottled water is
marketing and I don’t really buy into that very well.”


Colin Hinz’s suspicions are shared by Paul Muldoon, the Executive
Director of the Canadian Environmental Law Association. His
organization has done a lot of research on water issues. He says the
reality often doesn’t live up to the image that companies have tried
to cultivate.


“There’s no doubt in my mind that when a person buys bottled water at
the cost they pay for it, they’re expecting some sort of pristine 200
year-old water that’s from some mountain range that’s never
been touched or explored by humans, and that the sip of water they’re
getting is water that is so pure that it’s never seen the infringement
of modern society. In reality, pollution’s everywhere and there are
very few sources of water that has been untouched by human intervention
in some way, shape or form.”


Environmentalists say it’s not always clear what you’re getting when
you look at the label on an average bottle of water. First of all,
it’s hard to tell by looking at the label what the source of the
water is. In many cases, it comes from rural areas just outside of
major cities. It can even be ordinary tap water which has been
refiltered. The U.S. Food and Drug Administration does set maximum
levels of contaminants, and some labeling requirements as well. But
they don’t regulate water which is bottled and sold in the same
state. That’s one of the reasons critics of the bottled water
industry say the standards for tap water are at least as stringent,
and often even higher than for packaged water.


Lynda Lukasic is Executive Director with Environment Hamilton, an
environmental advocacy group in Ontario. She still has confidence in
tap water, despite the fact that the water supply in a neighborhood
in Hamilton was recently shut down because of the threat of
contamination.


“I think we’d all be better to focus on ‘what is the water
supply like in the place that we’re in?’ and ensuring that we’re
offering people who live in communities safe, affordable sources of
drinking water. And going the route of bottled water does a few
things. It creates problems in exporting bottled water out of
certain watersheds when maybe that’s not what we want to see
happening. But there’s also a price tag attached to bottled water.”


Paul Muldoon of the Canadian Environmental Law Association says there
are other costs associated with bottled water that can’t be measured
in dollars.


“Some of the costs of bottled water include the transportation of water
itself, and certainly there’s local impacts. There are many residents
who are now neighbors to water facilities with truck traffic and all
that kind of stuff. There’s also the issue of bottling itself. You’ve
now got containers, hundreds of thousands… millions of them probably.
So there is the whole notion of cost, which have to be dealt with and
put into the equation.”


There are many things to take into account when you pick up a bottle
of water. You can think about the cost and whether or not there are
better ways of spending your dollar. You might think about
convenience. And whether the added convenience is worth the price. Ask
yourself what you’re really getting. Read the label to find out
where the water comes from and consider whether it’s any better than
what comes out of your tap.


The bottom line is, be an informed consumer. And keep in mind that
the choices aren’t as crystal clear as the kind of water you want to
drink.

Power Company Switches to Natural Gas

The Bush administration is making it easier for coal-burning power plants to avoid upgrading to modern pollution prevention equipment. But in some cases the power companies are bowing to public pressure to reduce pollution anyway. The Great Lakes Radio Consortium’s Ann Alquist reports:

Transcript

The Bush administration is making it easier for coal-burning power plants to avoid upgrading to
modern pollution prevention equipment. But in some cases the power companies are bowing to
public pressure to reduce pollution anyway. The Great Lakes Radio Consortium’s Ann Alquist
reports:


Elizabeth Dickinson didn’t get any kind of warning about air quality in her neighborhood. She
really didn’t need one. She says couldn’t avoid noticing the pollution in the air.


“A couple years ago, there was almost a week where the air quality in my neighborhood was so
bad that you literally couldn’t sleep. There was a burning back in my throat.”


Dickinson lives in Saint Paul, Minnesota, not too far from one of the oldest coal burning plants
operated by Minnesota’s leading supplier of electricity, Xcel Energy.


She and many other people have been actively working to pressure the company to address the air
quality problems they believe are caused by Xcel’s older plants.


And in a rare move among power companies, Xcel Energy is doing something. In May 2002, the
company put forth a voluntary proposal to convert its two oldest coal burning plants to natural
gas. The oldest plant, Riverside, lies in northeast Minneapolis.


(sound of power plant)


Since it opened in 1911, the Riverside plant has changed very little when it comes to emitting
pollutants. It was grandfathered in under the Clean Air Act of 1970 – which means the plant isn’t
subject to federal environmental mandates.


It didn’t have to install modern pollution control devices unless it upgraded the plant. And now,
under the Bush administration’s new rules, even upgrading it might not trigger the threshold that
would require it to reduce emissions.


“For a little bit over two years, one of the first things I was charged with was to look at all the
emissions in and around southeast Minneapolis and Riverside plant came back as a sore thumb
because of the glaring emissions.”


Justin Eibenholtz is the environmental coordinator for a Minneapolis neighborhood improvement
group. He says that’s why Excel’s decision to convert Riverside to natural gas is such a big deal.
Once it’s converted, the old plant will cut air pollutants by 99 percent. Mercury emissions will be
completely eliminated.


Neighborhood groups such as Eibenhotz’s and big environmental groups alike are praising
Excel’s decision. The Great Lakes Program Coordinator for the Sierra Club, Emily Green, says
the reduction in emissions will mean a better quality of life for residents who live in the Great
Lakes region. That’s because the mercury and other pollutants that were emitted from the plant
often ended up in the Great Lakes through a process called air deposition. That meant pollutants
got into the food chain and contaminated fish.


“The Great Lakes are like a giant bathtub with a very, very slow drain, so that what we put into
the Great Lakes stays there.”


Green says the pollutants don’t go away. They just end up contaminating the air and the water.


“We swim in them, we drink them, you know, the fish swim around in them, and so it’s very,
very important that we recognize, despite their size, how fragile the Great Lakes are.”


Besides polluting the lakes, the air pollution drifted for hundreds of miles, causing health
problems. The effects are already apparent. An independent report commissioned from the
Environmental Protection Agency says pollution from the oldest and dirtiest power plants kills
more than thirty thousand Americans each year – almost twice the number of people killed by
drunk driving and homicide combined.


While the natural gas conversion won’t reduce the level of mercury in the Great Lakes
immediately, it will mean it won’t add to the problem. It also means a more efficient use of a
fossil fuel.


Ron Ellsner is the project manager for Xcel’s proposal.


“The new combined cycles that we’re going to install are on the order of 30 percent more
efficient than what our current coal cycle is. They do that much better a job converting that
energy into fuel into electricity.”


It comes at a cost, though. Xcel estimates converting its Minneapolis and Saint Paul plants will
amount to one billion dollars. By Xcel’s estimate, it’ll be the most expensive power plant
conversion in the history of the United States, and the cost of the conversion will be passed on to
its customers.


That’s fine by Elizabeth Dickinson. She says she, and her neighbors, were paying for it in other
ways already, such as additional healthcare costs. Dickinson says the estimated extra 15 cents a
day for her power bill will be worth it.


“You know, these are the hidden costs of coal burning and they’re huge, and you know, they’re
usually left out of these equations and we’re saying they can’t be left out any longer, they just
can’t be, because it’s too high a cost for us as a society.”


Government regulators still have to approve the plan. Minnesota’s utilities commission is
holding a final round of public hearings before voting for or against Xcel’s proposal to convert to
natural gas.


If the conversion is approved, it will likely put pressure on other power companies in the Great
Lakes region to do the same.

Natural Gas Shortage Causes Controversy

The government is expecting shortages of natural gas in the next year. A combination of
factors has caused reduced inventories of natural gas. Environmentalists say the Bush
administration is trying to take advantage of the situation by calling for more drilling on
public lands. The Great Lakes Radio Consortium’s Lester Graham reports:


In a letter to U.S. Senators, Energy Secretary Spencer Abraham indicated natural gas
must be conserved this summer by switching to coal or other fuel sources. Abraham also
suggested to boost supplies, the government should allow more drilling for natural gas on
federal lands. Some environmentalists see this as opportunistic. Patricio Silva is an
attorney with the Natural Resources Defense Council.


“We think that it’s reprehensible that the White House and some of their industry
supporters are using this opportunity to help subsidize the industry by giving away
billions of taxpayer dollars so that companies can drill and develop more of our protected
public lands.”


The shortage of natural gas is due to reduced storage capacity, hurricanes in the Gulf of
Mexico which stopped natural gas production, and low prices which curtailed
exploration. Inventories are down by 29-percent and prices are rising quickly.


For the Great Lakes Radio Consortium, this is Lester Graham.
