The Environmental Protection Agency has
a new water saving program called Water
Sense. It’s similar to the Energy Star label
for electronics. To get the Water Sense
program’s endorsement, toilets must use less
water. But, people have been complaining
about the old style low-flow toilets since they
were first required in the mid-1990s. Lester
Graham reports on what’s changed since then:

The problem with those old low-flow toilets is the companies didn’t really re-design them – they just made the tank smaller. Some of them just didn’t do the job.

Hugh Maquire has one in his home. He’s had a bad experience with his.

Maquire: “I had to flush my low-flow toilet six or seven times. What is that saving you?”

Graham: “ Doesn’t save you much water that way does it?”

Maquire Doesn’t save you much water at all. Plus it’s annoying. It’s embarrassing, ‘cause everybody’s hearing you flush the toilet six or seven times, wondering what the heck’s going on in there.”

So, we asked Matt Grocoff with Greenovation TV to set up a demonstration for us. Behind the Bgreen Retail Store in Ann Arbor, Michigan three different models of these new Water Sense low flow toilets are set up on five-gallon buckets so we can see what gets flushed… and what comes out.

Grocoff: “I always joke there were three things that set back the environmental movement: there was the original low-flow shower head, the original low-flush toilet and Jimmy Carter’s sweater. ‘Cause what that said to everybody was ‘You’re going to pay more for it; it was going to be less comfortable and you were going to have to sacrifice and it wasn’t going to perform as well.’ And with these new generations of redesigned toilets, you’re getting a higher quality product than even the existing one-point-six gallon or even a three gallon per flush toilet”

Graham: “Let’s see it.”

These toilets all have dual flush capabilities. A full flush is 1.28 gallons. A half flush – just 0.8. To prove how well they work, he’s just using the point-eight gallon flush. Matt’s got tennis balls, potatoes, and little rubber duckies.

Grocoff: “We got three duckies.” (flush sound)

Graham: “ Well, that seemed to work. No duckies. What’d you think of that, Hugh?”

Maquire: “I felt sorry for that ducky, but it was a great demonstration.”

And, again, that was the half-flush at 0.8 gallons, half of what the old low-flow standard was. Matt upped the ante.

Grocoff: “Two tennis balls and two potatoes. This is going to be the real challenge.” (flush sound)

Then more potatoes.
(flush)

And more duckies.
(flush)

Now, Matt’s demonstration is hardly scientific, but of the three brands we tested – a Kohler, a Toto and a Coroma – it appeared to me the Coroma worked best, at flushing duckies and potatoes anyway.

Rudy Wilfong is a dealer for Coroma. The toilet is made in Australia. He says Australia has had one-gallon-per-flush restrictions for 30 years, so they’ve designed them to work.

Wilfong: “And they don’t plug. They flush better than the 1.6 gallon toilets with half the water.”

And compared to the old low-flow toilets, you can expect to save about 1,000 gallons, per person, per year. They do cost more, but the pay back compared to a regular low-flow is about 2 to 2.5 years. If you’ve got one of those three-gallon-per-flush models, or even an old 6 gallon model, your payback will be a lot faster.

Graham: “Alright, Matt, I’m going to give you one more chance to impress me. What have you got here?”

Grocoff: “Alright. So, here we’ve got a full t-shirt. (flush) Very nice.”

Maquire: “Hey, Matt. I had a black t-shirt. Do you see it anywhere?” (laugh)

Graham: “Well, this was pretty impressive. Where can I get some more information about this?”

Grocoff: “Of course, you can go to Greenovation-dot-TV and you can see a video and some photographs of some of these toilets.”

Graham: “ Alright. Matt Grocoff of Greenovation-dot-TV. Thanks very much.”

Grocoff: “Alright. Thanks, Lester.”

Shawn Allee reports some
utilities are sending out info that might
get you to turn them down a bit:

Ever wonder if you’re an energy hog compared to your neighbors?

Well, some power companies are sending out graphs and charts to tell you.

Commonwealth Edison is a utility in Illinois.

It’s sending energy comparison letters to 50,000 customers this August.

Val Jensen runs the company’s program.

Jensen hopes competition will get people to conserve, because power bills alone don’t work.

“Despite pretty compelling economic reasons for customers to become more efficient at using energy, a lot of them don’t do it. Despite what they teach you in Economics 101, most customers don’t behave in the traditional, rational way.”

Jensen says, if enough people conserve energy, utilities can avoid building expensive new power plants.

Commonwealth Edison is just the latest utility to try energy comparison reports.

Power companies in New York and other eastern states will try them this year.

A new national report from a business

consulting group says energy efficiency

could be a better solution to meeting our

energy needs than building new power plants.

Shawn Allee reports that new finding

supports the Obama administration’s call for more

energy conservation:

The McKinsey consulting group crunches all kinds of numbers for corporations.

It’s latest report suggests its cheaper to improve efficiency in heaters, homes, and electronics than it is to build new power plants.

It’s a welcome message to Lisa Jackson.

Jackson heads the US Environmental Protection Agency.

“I’m optimistic about Americans, who have so much common sense, saying, listen, the best energy is the energy we never have to use. It’s cheaper, it certainly means that we can invest in ourselves.”

The McKinsey report finds energy efficiency is economical in the long run, but it’ll take millions of consumers and businesses to boost power efficiency all at once to make a difference.

The authors recommend government and banks find new ways to finance home improvements.

They also recommend stronger efficiency labels on household electronics.

Cities Share Cars to Save Cash

  • Cities have started to use car sharing programs in order to save money (Photo by Ed Edahl, courtesy of FEMA)

Car sharing has long been considered a green
alternative to owning a car. Both in terms of
expense and the environment. Companies like
Zipcar have made this concept mainstream in
a lot of urban areas. Now some cities are
trying out car sharing with their municipal
fleets. Tamara Keith has more:

Karyn LeBlanc works in the Washington DC department of transportation, so maybe it’s not surprising that she was one of the first to try out the city’s FleetShare program.

“It’s this one over here, right here, says 6067 is the license plate on it.”

A white Honda Civic powered by natural gas is waiting for her in a parking lot behind a city office.

She went online to reserve the car and it’s expecting her. At least the very smart computer transponder thingie in the front windshield is expecting her. LeBlanc presses something that looks like a credit card up to the device.

“So, we place this right here and you hear that little click and the car opens.”

The tank is full, the keys are inside, and LaBlanc is off and running.

(sound of driving)

“I would say I use fleetshare 2 or 3 times a week for any meeting that I need to go to or that I need to get to. So I go where I need to go. I park it. I go to my meeting. I get back in the car and I go back to the office.”

For people who use Zipcar this process will sound very familiar. The company has simply brought its car-sharing technology to Washington DC’s municipal fleet.

So far DC has about 60 new cars outfitted with Zipcar gear. But here’s the remarkable thing, those 60 cars are replacing 360. How? The new cars are getting a lot more use than the old ones.

“We’re getting up to 71% utilization on all these cars.”

When we spoke to him, Dan Tangerlini was DC’s Deputy Mayor.

We’re standing in the middle of a municipal parking lot. On one side there are empty spaces where the fleetshare cars park – on the other side there are just a bunch of white city cars.

“You see all this white iron around here. All these DC government vehicles that are kind of sitting static because these are assigned to individuals and those individuals don’t have a reason to be in that vehicle right now.”

Tangherlini says this system will save the city about 6 million dollars over the next five years – which is welcome at a time when budgets are tight.

Which might explain why Scott Griffith’s phone keeps ringing. He’s Zipcar’s CEO and says the company is now in talks with 25 cities.

“They all have the same challenges, not enough tax money, too many cars. They do need to move people around during the day and we’re trying to make that happen in the most efficient way.”

But this isn’t just about money. Griffith says when people share cars they end up driving more efficiently. When they have to book in advance rather than a bunch of individual trips they stack all their stops in one trip.

Car sharing isn’t new for cities like Chicago, San Francisco and Philadelphia. They’ve had programs in place for some time where city workers can use cars loaned out by private car sharing companies. They use the same one the public uses.

Eli Masser helped form the relationship in Philadelphia between the city and the non-profit Philly Car Share which he co-founded.

“One of the benefits of car sharing with municipalities or most businesses for that matter is residential demand is in the evenings and on weekends and most business demand and municipal demand is during the day.”

Which means those cars are busy well beyond the 40 hour work week. Critics say this model is far more efficient than what Zipcar is doing in DC. But Masser says there’s an even better model – a hybrid of DC and Philly.

Ideally cities would have a relatively small city-owned fleet of shared cars and even heavy machinery. But most city workers would car-share with the public.

Bringing a Fish Back From the Brink

  • The American Shad became so rare that hatcheries had to help restore depleted populations (Photo courtesy of the US Fish and Wildlife Service)

A million year old cycle of fish migration almost came to an end in the waters off of the nation’s capital. But a monumental conservation effort has brought them back from the brink. Sabri Ben-Achour explains:

A million year old cycle of fish migration almost came to an end in the waters off of the nation’s
capital. But a monumental conservation effort has brought them back from the brink. Sabri Ben-
Achour explains:

I bet you can’t recognize this sound.

It is the sound of a female shad – it’s a type of fish – having its eggs squeezed out into a metal
bowl.

“In the bowl, it looks like applesauce.”
That’s biologist Catherine Lim. We are on a boat in the middle of the Potomac, 20 miles south of
Washington DC, harvesting and fertilizing shad eggs. Lim picks up a male shad and gives it a
squeeze.

“Yeah, he sprayed out there.”

She mixes the brew around and adds water.

“We’ll bag them up and send them to the fish hatchery.”

This is all part of an effort to restore the population of the American Shad. For millions of years,
the large silver-iridescent fish have swum in from the Atlantic and up the rivers of the East Coast
every spring to spawn. They return to the same place where their lives began, guided by a
unique geological odor that seeps from the earth and mountains that feed each river.

Once upon a time – only a century ago – these fish were so numerous they turned the water silver
and made rivers move.

At least that’s what Jim Cummins says, he’s a biologist.

“On the Susquehanna, there were so many of them they created a wave as they came up the
river, a standing wave.”

On the Potomac they fueled entire industries. According to newspaper reports, Washington DC
exported 4 million barrels of salted shad every year in the 1840’s.

“The wagons would come into Georgetown were so heavy that they crammed up the city – I think
it’s the first report of gridlock in Washington.”

The fish fed more than just commerce – they nourish everything from crabs to dolphins. Bald
Eagles actually evolved to time their egg laying early, so their chicks would hatch just as the Shad
and their relatives appeared in the river. And then came overfishing, dams, and pollution.

“In the 1960’s, there were times when the migratory fish came up to spawn in the area and met
that pollution, and hundreds of thousands of them died and made a stinking mess.”

The clean water act was passed in 1972, but by 1980, the fish were almost wiped out. A
moratorium on fishing at the time was too little too late. Water quality gradually improved as
waste water treatment plants were upgraded and aquatic grasses returned. But still, no Shad.

So Cummins began the Shad restoration project.

They had to use several nets – each hundreds of feet long – just to catch one fish. They got help
from fisheries and even elementary schools. Dams were fixed to let fish go around them. The
Shad population exploded.

At a boat house just outside of DC, anglers Steve Bocat and Louis Covax are enjoying success
that up until recently, few alive have seen here.

“It was great we had incredible fishing. I mean, between the two of us, we had, what, 50-60 fish
up to the boat?”

Another sign of success, a pair of Bald Eagles recently returned to the area following the fish –
the first in decades.

Hotlines for Wild Animal Rescue

  • Possums pretty much just want to be left alone – and they let you know by opening their mouths full of teeth. It’s called an alligator gape. (Photo by Patti Roman)

Let’s say you find a baby chipmunk that fell out of a tree… or worse, you hit an animal with your car. Who do you call? Rebecca Williams has the story of people who feel it’s their duty to nurse these animals back to health… and get them back to the wild:


(sound of phone ringing)


“Thank you for calling the Friends of Wildlife hotline for squirrels, chipmunks and other small rodents. If you have rescued a small animal please keep it warm and quiet…” (beep)

There are hotlines like these set up all over the country. There are bunny hotlines, woodchuck hotlines… you name it and there’s a volunteer hotline for it.

The woman who answers the Possum Hotline is Patti Roman. She volunteers in Michigan. She has a basement full of baby possums.

“Mom has 13 babies so if you get a weekend where two or three moms are hit I’ll get a lot of babies in a few days.”

She says possums get hit by cars a lot. They love to eat roadkill, and they’ll just sit there in the middle of the road, staring at your headlights.

Possums are marsupials like kangaroos. Except they don’t hop out of the way. They keep their babies in their pouches. When a mom gets hit, a lot of times the babies will survive. Someone will find the babies and call the Possum Hotline.

Patti Roman says she’s had up to a hundred baby possums in her basement at one time.

She puts gloves on before she pulls a possum out of its terrarium. I don’t know if you know possums, but they look like a huge hairy rat on its worst day. But this baby possum is kinda cute. He’s giving us a sharp-toothed little grin. It’s a I’ll-rip-your-hand off kind of grin.

“He’s doing the alligator gape right now. But he’s not biting me, but he is trying to scare me.”

That mouth full of sharp teeth is your first clue that possums just want to be left alone. If your dog chases after one, the possum might play dead. Then it’ll get up and waddle off when you’re not looking.

Patti Roman takes care of the possums until they’re a few months old. Then she takes them into the woods and lets them go. She says wildlife is always better off in the wild. But she says she does get criticized for interfering with nature.

“A possum who gets hit by a car is not supposed to die. It has nothing to do with natural selection. And if we can help I think we should.”

But some scientists debate that. Jim Harding is a wildlife specialist at Michigan State University.

“I think the majority of rehabilitation efforts is often just based on a human need to care for things. It isn’t really related to conservation unless you’re dealing with a very rare species.”

Harding says rehabbing some types of common animals can actually make things worse. For example – he says there are so many raccoons that they can wipe out a lot of birds because they eat their eggs.

But Patti Roman says she really feels like she’s doing the right thing. She spent 18 years at the Humane Society rescuing dogs and cats. But she never knew for sure those animals would be placed in good homes.

“When you call to check on the animal a year later – it’s been given away or run away or accidentally been killed. It was breaking my heart. And after awhile I thought, you know, I enjoy doing the wild animals because when they’re ready to go I’m not dependent on people anymore. It feeds my soul. It really does. I do this and I feel very, very good every morning that I can save a life.”

She says when she lets the possums go they don’t look back. They just take off into the woods. And even if that little possum ends up getting eaten by a fox, Roman says that’s okay, because at least that’s natural.
