Green roofs are a popular, but
expensive, way for building owners
to prove their green credentials.
Shawn Allee reports some
researchers feel they might do even
more environmental good than they
thought:

The rock, soil and tiny plants in a green roof help insulate a building.
That can cut heating and cooling costs.

Researchers at Michigan State University think they’ve found another
benefit, too.

Brad Rowe says the tiny plants absorb carbon from the air. Rowe says the
plants are small, so this carbon sequestration effect is small, too. But
he says green roofs are still better than plain-jane roofs.

“You have all these roofs everywhere and basically, they’re doing nothing
– they’re essentially dead. So, putting plants on them is one way to
sequester carbon above ground, in the leaves and stems, the roots, and even
in the soil that’s on top of the roof.”

Rowe says if Congress ever puts a price on carbon emissions, green roof
owners might get credit for sequestering carbon – and that could cut a
green roof’s high price tag.

Tax credits for making your home
more energy efficient got a lot
of early buzz. The promise of up
to 1500-dollars back for insulation
and windows or efficient furnaces
led to a flurry of advertising.
Tamara Keith looks
into what might be stopping people
from taking advantage of the tax
credits:

My husband and I recently bought an older house that could no doubt use
some weatherizing. So, I called up Reuven Walder at EcoBeco.

(sound of door opening, people saying hello)

He’s a home energy auditor. He identifies ways to make a home more
efficient.

“I joke around, I consider myself an energy efficiency social worker.”

And he’s been getting a lot of calls lately from people like me – looking
to take advantage of the tax credits.

“Let’s look around the house and you can point out some things that are
of concern to you.”

Walder has all these cool tools, like an infrared camera that can see where
the insulation isn’t doing its job. He finds plenty of trouble spots,
including one in the attic.

“And if you put your hand in this little pocket here you can feel nice
cool air.”

That’s not supposed to happen.

“I’ll be honest with you. When I find these kinds of things, it makes my
day, because we get to fix them.”

Well, not all the time. Walder says only about a third of the homeowners he
works with actually follow through on his recommendations.

“I have talked to numerous homeowners and their primary reason for not
doing it is money.”

He says the tax credits are a great shot in the arm, but, for many people,
it’s just not enough. Part of the problem is, for simple weatherizing –
insulation, weather stripping, windows – the tax credits apply to 30% of
the cost of materials, not the labor. And labor is actually the most
expensive part.

“Our economy is just so slow right now that people are just hesitant to
spend any amount of money because, regardless of the incentive, they’re
still going to have to spend a lot of money to make the improvement. It’s
not going to cover a significant portion of the cost.”

At this point, federal officials don’t know how many people have been
inspired by the stimulus package to do work on their homes. They won’t know
until everyone files their taxes in April.

“It’s definitely driving additional business.”

Matt Golden is president of Efficiency First – the national association for
the home performance retrofitting industry. But he isn’t totally sold on
the way the stimulus package is distributing the tax credits.

“The biggest incentives are for the most expensive fanciest equipment and
as you move towards the most cost effective stuff, you get much smaller,
incremental incentives.”

So, there’s big money for solar panels and geothermal heating systems. And
if you want to put in a tank-less hot water heater or a super efficient
furnace, here labor costs can be counted towards tax credits. Golden says
the smallest credits go to insulation and other simple steps.

“It’s actually kind of an impediment to the type of retrofitting projects
that have the biggest return on investment, bang for the buck and create
the most jobs.”

In my house, Walder estimates we need almost $6,000 worth of work. But,
because not all of it qualifies, I’ll only get $600 of it back from the
government – but we won’t see the money until tax season.

I’ll admit – it’s a lot more money with a lot less of a tax benefit than I
was expecting, and that’s probably what’s giving some homeowners pause.

Solar Panel Prices Drop

  • Experts say one of the main reasons solar is cheaper is because of Spain. (Photo courtesy of National Renewable Energy Laboratory)

There’s a big push to find alternative sources of energy. Problem is, a lot of alternative energy is just too darn expensive. The cost of solar energy, however, is on the decline. Jennifer Guerra reports:

There’s a big push to find alternative sources of energy. Problem is, a lot of alternative energy is just too darn expensive. The cost of solar energy, however, is on the decline. Jennifer Guerra reports:

The price of solar panels took a huge drop this year.

Experts say one of the main reasons solar is cheaper is because of Spain.

The country is a big buyer of solar panels, or what are called PV modules, largely because Spain offers generous incentives for people who buy them.

Galen Barbose is with a federal research lab in Berkley, California. He says, because of the economic crisis, Spain had to slash those incentives.

“And so demand in Spain dropped fairly significantly. And so what we’ve seen over the past year is a glut in the global supply of PV modules. And that has led to a fairly significant drop of the wholesale price of PV modules.”

The cost of solar still isn’t on par with conventional energy, but Barbose says things are headed in that direction.

Green Crime: Stealing Solar Panels

Solar panels are expensive and
increasingly in demand. And now,
many communities are learning of
their solar array’s value the hard
way – they’re being stolen. Conrad
Wilson tells up about this new type
of “green crime:”

Solar panels are expensive and they’re increasingly in demand throughout the
world, so it sands to reason solar panels have become an attractive target for
criminals.

Recently, 30 panels were stolen from one of the “greenest” buildings in Colorado.
Ninety solar panels valued at $135,000 were swiped off a waste water treatment
plant outside San Francisco.

Monique Hannis is a spokesperson for the Solar Energy Industries Association.
She says, over the last year, solar theft has become a greater concern.

“It’s really just emerged as an issue we need to be watching, really, in the last
year. And the reason is, as solar becomes more prevalent and people
understand the value of the solar panels, it’s just like any other target for theft.”

Currently the group doesn’t track the crimes, but since more panels are
disappearing Hannis says they’ll likely start.

This type of “green crime” is nothing new in developing countries. Lori Stone is
international program manager for Solar Energy International. It’s a Colorado-
based nonprofit that trains students world-wide for careers in the solar industry.
Stone says in some cases the solar panels are gone just days after they’re
installed.

“If somebody really wants to steal solar panels, it’s pretty hard to keep them from
doing it. You know, there’s some new things that are coming out now with ways
to lock them and stuff, but they’re costly and so a lot of these developing country
systems, solar home systems, are pretty easy to take.”

In Kenya, last September, thieves unsuccessfully tried to swipe solar panels on
the house belonging to President Obama’s 86 year-old step-grandmother.

As the solar industry becomes more established, security is gearing up. It’s
becoming part of installing a solar array.

The Solar Industry’s Hannis says manufactures are making things harder for
thieves by adding tracking numbers as part of a recycling program.

“This same system could be used to at least track the location of panels, the
rightful owner of panels going forward, similar to a VIN number of a car.”

Hannis says consumers should be wary of purchasing panels from online sites
such as eBay or Craigslist because they could be buying stolen panels.

To ward off thefts, some go so far as to post night watchmen. Other larger arrays
are equipped with cameras and fences. But there’re also more affordable
options.

Bryce Campbell is president of Bryce Fastener Company, an Arizona based
business that specializes in a unique type of security bolt that acts like a key. The
bolts cost about two dollars per panel.

“The solar industry is starting to say, ‘Hey, what do we do?’ Ha ha. Are we going
to up security systems up here, cameras? Not really effective in places where
most of these solar arrays are laid out.”

Campbell says solar companies began contacting him about a year and a half
ago. Now he gets orders daily.

For Campbell, it makes sense considering people are parking thousands of
dollars on roof-tops and in fields.

But a new study finds that we should
also be considering where we live. Julie
Grant reports that living in the suburbs
can create extra carbon emissions:

Most Americans live in or near big cities – but those in the suburbs have to drive a lot.

The National Research Council completed a study for Congress. It finds that building housing closer together near urban centers could reduce the amount people drive. That would save energy and cut greenhouse gas emissions.

Marlon Boarnet is a professor at the University of California, Irvine. He was on the study committee.

“The best evidence out there leads us to believe that people who live in more dense development do in fact drive less. And we feel that the evidence can conclude that that’s a causal relationship.”

Even if single-family homes were built closer together, it would mean less greenhouse gases.

Some experts in the study say the U.S. could reduce emissions by up to 11% in the next 40 years – just by building housing closer together.

Shrinking a Rust Belt City

Folks in lots of rust-belt cities
are used to hearing about the declining
population. Over the past thirty years,
people have been moving away from
cities such as Cleveland, Detroit,
and Indianapolis. Julie Grant visited
one city that’s embracing its newfound
smallness – and trying to un-build some
of its neighborhoods:

For decades, Youngstown, Ohio has been a city looking to its past. It was booming in the 1950s. The steel industry brought good paying, reliable jobs. City leaders back then planned for the population to blossom above 200,000.

It never got there. The steel mills closed, and people left. Youngstown lost a lot of people.

Mayor Jay Williams says that about ten years ago, they started holding community meetings. They wanted to figure out how to make the city run better for the 80,000 people who are still here.

“While it was an acknowledgement of the fact that we were going to be a smaller city, it also was an understanding that smaller didn’t have to be inferior. And that started a series of things that led us to where we are today.”

Now they are in the process of demolishing 2,000 abandoned homes and other buildings. They actually want the people to leave some areas – so the city doesn’t have to spend money on things like power, utilities and snow plows on those streets.

Mayor Williams says, in some neighborhoods, there are entire blocks that are abandoned, except for one or two houses.

“So from that standpoint, we do have a moral, and an ethical and legal obligation as a city to provide certain services. But what we’re trying to do is balance that with the fact that sometimes it doesn’t make economical or business sense.”

A lot of the times those holdouts are older folks, who don’t want to move – and might not accept that the city doesn’t plan to return to its former glory. The new leaders want to embrace the city’s new small-ness – and improve the quality.

Thing is, most of the leaders in Youngstown today are – young. The mayor is 37, the Congressman is 36, and Community Organizer Phil Kidd just turned 30. Kidd says his generation doesn’t really remember those glory days of the steel mills.

“So we don’t remember how things used to be. We’re not bitter about what happened. We are here by choice in Youngstown as young people. And when you bring that to the table, there’s a different type of lens in which you look at Youngstown, I think.”

Kidd says his generation can see that the infrastructure needs to be the right size for the people who live here now.
He says making the necessary changes will open up all kinds of new opportunities for Youngstown.

“And we look at it as almost a blank canvas, in a way, to really be progressive about being as kind of new urban pioneers, in a certain regard. But with respect for the history for this community.”

And that new vision is inadvertently attracting some young people back to the city.

Maggie Pence grew up in Youngstown, and like a lot of people, moved away after college. She needed a job. And some hope for a bright future.

“When I left, I thought, ‘this is just, nothing’s ever going to change.’ It’s always going to be lamenting the steel mills, waiting for the next big savior. It was the waiting, just waiting, to see what was going to happen.”

Today, Pence is swinging her 11-month old daughter at a park just north of downtown Youngstown. She and her husband are renovating what was a boarded up, foreclosed house nearby.

Pence largely credits city leaders for her decision. When she saw their plan, called Youngstown 2010, she decided it was time to move her family back from Brooklyn, New York, to Youngstown.

“Yeah, I mean, seeing 2010 and seeing what they were doing and having make sense to me made me realize that you could come home again, kind-of. I mean, okay, there’s a future.”

The city isn’t sure exactly what it’s going to do with all the new open space – once all the abandoned houses are demolished. Some people are planting trees and neighborhood gardens. Community leaders say the people who live here will have to decide what they want the new city to look like.

A lot of shrinking cities in the Rust Belt will have to figure that out. Sooner or later, shrinking tax bases won’t support all those barely used streets, sidewalks and water lines.

Some EPA scientists say greenhouse gas emissions are not just about tailpipes and smokestacks. They say you have to look at the big picture.

42% of the greenhouse gas emissions in the US are related to everything that goes into creating the food and products we use, and then throw away. So, they say more reduce, reuse and recycle. And, a lot of emissions are caused by urban sprawl. We have to drive everywhere.

Brigit Lowery is with the EPA. She says there are ways to reduce those emissions too.

“Encouraging compact development, such as promoting smart growth. But also reducing development pressures on green space, such as redeveloping formerly contaminated properties.”

Lowery said she knew going into it that land use and resource management contributed to climate change. But she was surprised by how much.

Greenovation: Low-Flow Toilets

The Environmental Protection Agency has
a new water saving program called Water

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.”

Lester Graham reports, they’re now

the old shingles:

Two-thirds of American homes have asphalt shingle roofs. They last twelve to twenty years before they need to be replaced.

Since most of the material in asphalt shingles is the same stuff used in asphalt pavement, that’s where they’re going.

(sound of machinery)

New businesses are popping up across the nation that take the shingles.

Chris Edwards is co-owner of Ideal Recycling in Southfield, Michigan. He says roofers can dump old shingles at his place cheaper than taking it to the landfill.

“And then they can also sell it to their customers that they are recycling and it’s green. So it does help the contractors quite a bit.”

Several states are studying how the material holds up for asphalt roads, but for now most of the singles are mixed in asphalt used for parking lots.

Stimulus Funds for Home Weatherization

The government stimulus package included billions of new dollars for home weatherization programs. The money is used to help low income folks make their homes more energy efficient. But some critics say it’s not a good use of federal tax dollars. Julie Grant reports:

Chris Graham spends his days checking the energy efficiency of people’s homes.

Today he’s at Sandra Richards’ in Mogodore, Ohio.

Graham: “Hi Sandra.”

Sandra: “How are ya?”

Graham: “Wonderful. And you?”

Sandra: “Better.”

Graham: “Better?”

Sandra is 55. Her house is clean and neat. She was a nurse for many years, but today she’s sitting on the couch, watching TV. A broken foot spiraled into problems with her knee and hip – and other health problems.

“I mean I’ve just had so many things go on in such a little time. I was working 12 hour days, and one month later, I couldn’t work at all.”

Sandra qualified for the home weatherization program because she doesn’t have much in the way of income anymore.

Chris Graham says he’s been to a lot of homes where people are far worse off. They can’t get around, they don’t have money coming in, and their houses get cold in the winter.

Graham heads to the basement.

“The first thing we have to make sure is that the heating unit is not in terrible, dilapidated shape. And that it does not have more than a specified amount of carbon monoxide in the flu gasses.”

He turns on the furnace and sticks a probe into the flu pipe.

(sound of a tester)

Grant: “Looks like a receipt came out.”

Graham: “It kind of is. It tells you exactly what was going on there.”

Looks like Sandra’s furnace is running pretty well. 81% efficiency.

But Graham sees evidence of carbon monoxide on her old water heater.

“It’s 17 years old and it just plain needs changed. It’s got burnt, scorch all over it. So we’re gonna do that.”

That could cost more than $1,000.

But the home weatherization program can afford it these days. The stimulus packaged included $5-billion for this kind of work – compared with less than a quarter of a billion dollars last year. The new money has to be spent within two years.

And some people think that’s just too much money – too fast. Leslie Paige is with a taxpayer watchdog group called Citizens Against Government Waste.

“There’s always a lot of waste in government spending anyway, but when you spend it quickly and there’s very little oversight, that’s almost a prescription for seeing a lot of that money go for waste and fraud and losing to abuse.”

That kind of criticism is shocking to David Shea. He’s director the Community Action Council of Portage County, Ohio – the organization that hires inspector Chris Graham.
The weatherization program has been around since 1976 and Shea says they have to report their spending in about a hundred different ways.

“It’s not like money is being thrown out at agencies and just say, ‘oh go out and do it.’ There are volumes and volumes of written regulations that have been around for a long time. We do so much sophisticated reporting; they know how every dollar is being spent. Always. Always.”

Shea’s office used to have one crew out weatherizing homes around the county. Since the stimulus money’s come in, he’s hired a second crew. But there are so many people wanting their services, the waiting list is still years long.

(sound of a fan)

Back at Sandra Richards’ house, inspector Chris Graham has sized a big fan into the front door. He’s depressurizing the house – so he can see where air is escaping. Graham says she’s going to need some doors sealed and new insulation in the attic.

He says Sandra will feel more comfortable, so she won’t need to turn up the heat in the winter. That means she’ll save on energy costs, and will use less fossil fuels.

That’s the whole idea of this project – to use less energy in the future, and to help millions of families that couldn’t afford to improve things on their own.
