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.”

Enviros Say No Tax Money for Manure Digesters

More farms are trying to turn cow manure into electricity. But some people say the government should not be paying for the process. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

More farms are trying to turn cow manure into electricity. But some people say the
government should not be paying for the process. The Great Lakes Radio Consortium’s Chuck
Quirmbach reports:


The federal government recently gave 14 million dollars to six Great Lakes states for renewable
energy and energy efficiency projects. Some of the projects are manure digesters, which capture
the methane from large amounts of animal waste and turn the gas into
electricity.


But Bill Weida of the New York-based Grace Factory Farm Project says the digesters do little to
reduce odor and nutrient problems at large farms. He also says the amount of electricity produced
is relatively small for the expense.


“We are subsidizing a program, which is going to produce energy at a higher cost than other
alternatives would, for example wind.”


Weida says the manure digester technology should be forced to stand on its own economically. But
the U.S. Agriculture Department says it’ll continue to consider digester proposals.

Energy Use at All Time High

This month, U.S. electric utilities have been setting records for electricity
output. So far, the grid has held up. But the electric industry says more
has to be done to keep up with growing demand. The Great Lakes Radio
Consortium’s Lester Graham reports:


With drought and high heat, demand for electricity in many parts of the
nation has hit record highs and the power companies have been able to meet
that demand with few problems. Jim Owen is with the Edison Electric
Institute, an electric industry association. Owen says places where there
have been black-outs in the past are keeping up this summer.


“Take Chicago, for example. Here a couple of weeks ago they set
all-time record demand for elecricity pretty well without any reported
problems. So, we are meeting demand pretty well all across the country.”


Owen says new peaker plants that come on only during high demand periods and
a few new big traditional electric generating plants have helped avoid
problems. But while the capacity has increased in the past few years, demand
has grown faster. Owen says that gap needs to close.

Green Technology Can Defeat Terrorism

Small-scale on-site power generation technologies help protect the environment. Will they also help to protect us against terrorism? Great Lakes Radio Consortium commentator Byron Kennard argues that they can:

Small-scale on-site power generation technologies help protect the environment. Will they also help to protect us against terrorism? Our commentator Byron Kennard argues that they do.


Like every American, I am mourning the tragic losses that terrorists have inflicted on our nation. But I mourn too because I fear that in the aftermath of these attacks, environmental protection efforts will be sacrificed to the awful necessities of war. I am reminded of a remark Tolstoy once made to a young friend, “You may not be interested in war,” Tolstoy warned,” but war is interested in you.” War’s interest in the young is fully matched by its interest in the environment.


Apart from what the US does to go after bin Laden, we must also pursue peaceful solutions to this challenge. The best of these options is to vastly increase economic opportunity for the world’s poor. After all, it’s their desperation that provides the breeding grounds for fanaticism. As Jessica Stern, author of The Ultimate Terrorists, observes: “Force is not nearly enough. We need to drain the swamps where these young men thrive. We need to devote a much higher priority to health, education, and economic development or new Osamas will continue to arise.”


Economic development will be hard to achieve and will take much time. But in it environmentalists can find some solace. There are environmental ways to develop economies and often these make the most sense for the world’s poor. For example, two billion people in the world have no access to electricity. Providing them electricity for lighting, clean water, refrigeration and health care, and radio and television is perhaps the best single way “to drain the swamps.” The best way to make electricity available to the world’s poor is through on-site generating technologies that are the environment friendly.


These “micro power” devices generate electric power on a small scale close to where it is actually used. They include fuel cells, photovoltaics, micro generators, small wind turbines, and modular biomass systems. For instance, a micro generator the size of a refrigerator can generate 25 kilowatts of electricity, enough to power a village in the developing world.


The environmental approach toward energy sufficiency in developing nations has been to utilize micro credit. That means providing poor people with affordable mini-loans to purchase on-site energy generators, or micro generation. Currently the US leads the world in exporting solar electric, small wind, fuel cells, and modular biomass systems to the developing world. Such exports of energy generation have become a $5 billion per year market, so this environmentally benign strategy is also economically productive. In short, electrifying the poor regions of the world will benefit our people, our planet and the cause of peace.

State to Force Mercury Reductions?

Mercury emissions from more than 150 coal-burning power plants across the Great Lakes are coming under greater scrutiny this summer. Several states are considering ways to reduce those emissions. Wisconsin could become the first state in the nation to issue rules requiring large mercury reductions. The Great Lakes Radio Consortium’s Chuck Quirmbach has the story:

Utilities Prepare for Summer Demand

As summer approaches power companies will brace for rising demands for
electricity. During peak demand periods in past summers, utilities have
been caught short of power. However, deregulation of the electric power
industry has led to some innovative changes. The Great Lakes Radio
Consortium’s Lester Graham reports:

Dump Generates Creative Power Solution

Methane is one of the main by-products of landfills. It’s also a
fuel, which can be used to create electricity. In 1978, the federal
government began requiring utilities to buy this methane-generated
power. But as energy prices dropped, methane producers found their
profits disappeared as well. As the Great Lakes Radio Consortium’s

Methane is one of the main by-products of landfills. It’s also a fuel, which can be used to create

electricity. In 1978, the federal government began requiring utilities to buy this

methane-generated power. But as energy prices dropped, methane producers found their profits

disappeared as well. As the Great Lakes Radio Consortium’s Karen Kelly reports, they’re looking

for new alternatives:


(sound of blower)


Frank Lavadera stands proudly next to a small, green pipe sticking out of the ground. It’s

attached to a fan, which is sucking methane gas out of this landfill in Saratoga Springs, New

York.


“It pulls the gas from the landfill to this particular point and pushes it across the street to

where the engine system is, to where it’s used.”


(sound of skating)


Where it’s used in the town’s skating rink. The landfill produces enough methane to provide

eighty-five percent of the rink’s electricity. The methane is pumped into a generator. That

produces the power that freezes the ice, keeps the rink lit, and heats the water for the showers.

Lavadera designed the project. He’s an engineer at Cluf, Harbor and Associates in nearby Albany.

He was originally hired to close the city’s landfill, which is filled with horse manure from the

nearby racetrack.


“One of the things we found was that this particular landfill had a tremendous amount of methane

gas, above and beyond what would normally be expected. And as a result, we needed to collect this

methane as opposed to just passively venting gas into the atmosphere. But simultaneously, the city

constructed this ice skating rink, and it was very natural connection that we’d match the two up

together to utilize the gas.”


The city is now saving fifty-thousand dollars a year in utility costs. At one time, they probably

would have sold the electricity to a power company and made a profit. Utilities are required to

buy methane-generated electricity from landfills at the same price it costs the utility to make

it. The problem is, the overall price of producing electricity has dropped drastically. In New

York State, it’s gone from six cents per kilowatt-hour in the 1980’s to about two cents today.


Shelley Cohen is head of the EPA’s methane outreach program.


“Utility prices in many states are still very cheap and they’re not able to offer prices for the

landfill gas that make it economical to develop a project. That being said, the landfill and the

landfill developer generally look for other options for developing gas projects.”


Cohen knows about eighty landfills in the U.S. that have found other ways to recycle their

methane. Many simply use it themselves to heat their buildings and run generators. Others sell it

to neighbors. There are asphalt and paper companies that use methane to run their boilers. And in

Canada, the methane from one landfill heats four greenhouses. Cohen says these projects are making

good use of one of the most potent greenhouse gases.


“The environmental benefits are tremendous. Because you’re capturing the methane from the

landfill. You’re reducing those emissions from the landfill and then you’re somehow utilizing it,

which means you’re also offsetting the need to use other forms of polluting energy, such as coal.

So it has this double environmental benefit.”


But Frank Lavadera says landfills still shy away from these projects. For one, they have to build

a system to convert the methane to electricity. In Saratoga Springs, that cost more than a million

dollars. And two, the farther the methane has to travel, the more expensive it’ll be. So, they

need to have a willing neighbor.


“That’s what made this project work very well, is we had the ice skating rink directly across the

street from the landfill. That probably is what will drive methane gas projects in the future as

time goes on, is matching up landfills with high users that might be close by so they could

effectively utilize the electricity.”


There’s another possibility on the horizon. Environmental groups are pushing for a federal tax

credit to make it easier for landfills to produce electricity. John Skinner is president of the

Solid Waste Association of North America.


“Our proposal is for a federal tax credit for landfills that use the methane gas as a fuel and

that will adjust the economics so that it’s economically feasible to do so. There’s probably

another 250 to 300 that would come on-line that won’t come on-line otherwise.”


Skinner says a previous tax credit helped create more than two-hundred new projects. But it

expired two years ago. The current proposal is expected to come to a vote in the House sometime

next year.


(sound of skating)


Meanwhile, the more creative landfill owners are forging ahead. They have to find a way to get rid

of their methane. But rather than seeing it as a waste product, they view it as a resource. Now,

they just have to find someone who’s willing to use it.
