People fed up with hearing
about an energy crisis talk
about going off the grid.
In the US, the solution is
to install solar panels on
your roof or put up a wind
turbine. But a village in
Germany has taken a different
approach. In the final part
of our three-part series on
biofuels in Europe, Sadie
Babits explains:

The village of Juhnde sits between rolling farmland and woods. The first buildings went up more than a thousand years ago. It looks like a lot of German villages – narrow streets, terra cotta roofs, and a towering church steeple. But talk to anyone here and they’ll tell you Juhnde is no ordinary town. It’s the first community in Germany to be powered and heated by cow manure and grain.

“This is the biogas power station on this side.“

That’s Gerd Paffenholz. He’s lived here in Juhnde for 20 years. He volunteers to show visitors, like me, the village’s bio-energy plant.

“This is the wood heating system and what you don’t see is the network that deliver the hot water in the ground.”

Paffenholz stands on top of an underground storage tank. The liquid manure in here gets pumped over to a massive green tank. That’s the anerobic digester. There, micro-organisms have a hay day eating manure and grains supplied by farmers in Juhnde. The bacteria create biogas, which then gets combusted into heat and electricity. It’s pretty silent outside the power station but open the door…

(engine sound)

That’s the sound of 700 kilowatts of power being generated. The electricity gets sent to the public network. It provides this village of 750 people with renewable power. There’s an added bonus – energy that’s normally lost while making biogas gets captured and is used to heat water. That hot water gets delivered through a series of underground pipes to heat most of the homes in Juhnde.

The village’s bioenergy plant went live five years ago. The price tag? Nearly 8 million dollars. The money came through a government grant and from residents who each ponied up thousands of dollars to join the plant cooperative. The village has also cut its greenhouse gas emissions in half already meeting targets set by the European Union for 2050.

“It shows you what some wise investments and collective thinking can make happen.”

That’s Jim McMillan. He researches biofuels at the National Renewable Energy Laboratory in Boulder, Colorado. He says Juhnde has created an attractive model that could work in the Northern US and Canada where people are more remote and winters are long and hard.

“It’s a good model but Europe, I mean, they’re built out much more than we are and they are doing a lot more in building. They’re density of building, the size of their square foot of their homes are much more right size and so these solutions are easier to implement there than they are here I mean we have a lot more big homes that require a lot more heat.”

Our attitudes are different too. It took several years to get Juhnde’s residents to buy into the idea of going off the grid but now most everyone is on board. Here in the U.S. we’re a lot more individualistic. But McMillan still sees a lot of promise in what Juhnde accomplished.

“So one village is a good example but we need to apply it across the board.”


Other villages in Germany are building bio energy plants. In the U.S. a few towns are attempting parts of Juhnde’s efforts. Reynolds, Indiana replaced the town’s vehicle fleet with cars and trucks that run on bio fuel. It’s now working with a company to turn algae into power. And in Grand Marais, Minnesota, they want to build a central heating system for the town that burns wood chips from the local saw mill.

We’ve all heard about the
environmental problems our
gas-guzzling cars and trucks
cause. But some researchers
say our vehicles aren’t the
biggest energy hogs. The biggest
energy users actually live
in our homes. Julie Grant
reports about the new book
‘Time To Eat The Dog?’ about
the wasteful ways of our pets:

Robert Vale is sorry. He didn’t set out to incriminate Fido. He and his wife Brenda Vale specialize in sustainable living at Victoria University in New Zealand. And they just wanted to see how much of the world’s resources it takes to do things like eat, work, play sports, and own pets.

“The thing that most surprised us, and was the most unexpected was the scale of the impact of pets – which was really, really high.”

Vale says a big dog, like a German Shepard, actually has a bigger ecological footprint than an SUV.

To measure the ecological paw-print of pets, the Vales looked at the ingredients in common brands of dried pet foods. Based on recommended portion sizes, they calculated that a medium sized dog would consume more than 3 ounces of dried meat a day. To get that much dried meat, the Vales found, it takes nearly a pound of fresh meat. Add that up each day, and they concluded a medium sized dog eats about 360 pounds of meat a year!

Robert Vale says raising that meat – beef, lamb and chicken – has an environmental impact.

“And we did the calculation based on a dog eating chicken, which is a fairly low footprint meat, rather than say beef, which is a fairly high footprint meat. So, we tried to bias it in favor of the dog. But it still came out really big. It was a big surprise, really.”

Vale says the dog takes more than 2 and a half times more energy and resources than building and driving an SUV 6000 miles a year.

These numbers aren’t just coming from the Vales.
The New Scientist Magazine asked the Stockholm Environment Institute in England to calculate a dog’s paw-print, and the findings were almost exactly the same.

But none of this really computes with dog-lover Meredith Mull. She doesn’t understand why Robert Vale would even look into this.

“He must not have a pet. He must not know what it’s like to be loved by an animal and take care of it and have it give you nothing but respect and loyalty and love. He must not know what it feels like.”

The Vales don’t have any pets. They used to have cats and other animals. But when they died, Robert Vale says they felt they shouldn’t replace them and use more of the world’s resources just to give themselves a little more comfort.

“We are increasingly pushing up to a question of limits. What can we have, what, everything. I think to some extent, that’s why it’s unpopular. We’ve all been brought up to believe that not only can we have more of everything, but it’s our right to have more of everything.”

But some people think the Vales are barking up the wrong tree.

Chetana Mirle works on global warming issues at the Humane Society of the United States. She says instead of blaming dogs, people should look at what they, themselves are eating – and how that contributes to environmental problems.

“So to me, I felt like, ‘are you kidding me?’ Um, we’re worried about our pets, and what our pets are eating instead of what we’re eating, and what our consumption is about – which has such a huge disproportionately large impact on climate change and the environment in general.”

It’s not that the researchers want people to blame dogs and cats instead of themselves. They say they just want people to understand that each choice we make – right down to whether we have pets – has an environmental impact.

There’s a lot of talk about
conserving energy, but many
homeowners are not taking
advantage of the tax credits

their homes. Many are more
intrigued about solar panels
and generating their own power.
Amory Lovins is an inventor,
author, and the chief scientist
at the Rocky Mountain Institute.
Lester Graham talked with him
about conserving energy at home:

Lester: When I talk to some of my friends about energy consumption, they immediately jump to installing backyard wind turbines or solar panels; just getting off the grid. And I always ask, well, have you added insulation your attic? It seems like some of us are really into those gee-whiz aspects of renewable but we tend to overlook conservation, that’s something you’ve stressed. Why?

Lovins: Well, efficiency, which I use instead of conservation cause it unambiguously, means doing more with less is faster, cheaper, easier, than any kind of supply. Look, if you can’t keep your bathtub full of hot water because it keeps running down the drain the first thing you do is get a plug before you go looking for a bigger water heater. Then when you get a water heater, it will be a lot smaller and cheaper and work better. So efficiency first is a wonderful adage, most people live in houses with a square yard of holes in them. Of course if you live in a sieve, it’s hard to stay warm. So, first, you start with stuff like weather stripping and caulk, and if you can you get a house doctor to come do a house call with diagnostic equipment and diagnose you houses chills and fevers. But uh, even in our house which is one of the most efficient in the world, uh, we still need to the blower door test and caulking every few years because with changes in humidity the wood works in and out and you have to renew this stuff occasionally. But the benefits are huge.

Lester: How far can we really go in saving energy at home?

Lovins: If you’re really conscientious about it, most people can save around half to two-thirds of their energy. That’s partly by draft proofing, insulation, and perhaps, although they’re often costlier, uh window improvements. I’m sitting under some windows now that insulate like fourteen sheets of glass but look like two and cost less than three. Then also it means whenever you get lights or appliances, you get the most efficient you can, so after some years you’ve turned over the stock and if you’re ever going to buy an appliance, go to aceee.org. The American Council for an Energy Efficient Economy posts their list of the most energy efficient appliances. Of course, a minimum, you should get energy star, that at least knocks the worst stuff off the market. But within the energy star category, there is quite a lot of variation and it is worth shopping for the best ones.

Lester: What about the upfront costs of new appliances, new windows, new furnaces, things like that?

Lovins: For many kinds of appliances, there isn’t even any correlation between efficiency and price, but if there is, it’s probably still a very good deal; a much better return than you can get in any other form of investment and with much less risk. Think of it as money very well spent and of course, if you had first done the very cheap stuff like stopping up that square yard of holes in your house, the wind doesn’t whistle through, it saves so much upfront that it helps pay for everything else. The whole package is really quite an enticing return.

Lester: Amory Lovins consults on energy issues and he’s the chairman of the Rocky Mountain Institute. Thank you for your time.

Lovins: Thank you.

When you’re planning a home
improvement project, you can
be overwhelmed with decisions
about the right materials, the
right quality, and the right
design. Trying to keep it eco-
friendly on top of everything
else just adds to the confusion.
Lester Graham reports it can be
as simple as finding a label:

Julia Weinert and her boyfriend like the idea of making their place nice, but even something as simple as painting causes concerns.

JW: “We want to support environmentally friendly options and we just don’t want to be smelling it for three days out and have to be running the fans. We just want it to be convenient and we think it would be an easy thing to do.”

LG: “Well, you’re in luck. We’re at the local Home Depot and we just happen to have Greenovation.TV’s Matt Grocoff here. Matt, you’ve got some advice for her.”

MG: “And it’s really, really simple. When you’re trying to find a paint that’s healthy for you or another product, you shouldn’t have to be a chemist when you go to the store. There’s a really simple thing you can look for. Just look for the simple GREENGUARD label. GREENGUARD is an independent organization that lets you know with a simple label that that product is safe for you.”

So, none of the really strong paint smells that mean polluting chemicals are being released. GREENGUARD Environmental Institute sets indoor air standards for products and buildings. Julia and I sniffed a can of paint WITH the GREENGUARD label, and then one without.

LG: “I’ll let you sniff first.”

JW: Okay. Oh! Yeah! Oh my gosh! That is ridiculous. I mean, it smells so much stronger than this one. You can’t even smell that one compared to this one.”

A gallon of paint with the GREENGUARD label DOES cost a few dollars more, maybe as much as ten bucks.

Matt then herded us to another part of the store, the plumbing section, where Julia and I were confronted by all kinds of shiny chrome and brass faucets.

JW: “There’s a whole wall, a whole aisle of faucets here and I just don’t know which ones to look for.”

LG: “So, Matt. You got any fancy labels here?”

MG: “Absolutely. Again, if you’re looking for that eco-friendly option, a way to save yourself some money and some water, it’s simple. Just look for the WaterSense label. The EPA does EnergyStar labels for appliances. The EPA also does WaterSense label for plumbing fixtures.”

WaterSense means the fixture – whether a faucet, shower head or toilet – will use less water but still works well.

As we wandered over to the lumber section of the store, Matt told us the last label he wanted to show us is the most ignored label – and it might just be the most important one.

MG: “FSC stands for the Forest Stewardship Council. And what that means is they’ve made a commitment that they’re not going to be tearing down forest and clear-cutting them in order for you to build some bookshelves in your home. This is one of the biggest causes of greenhouse gases is that we don’t have these forests capturing this carbon any more. Instead of having to have a PhD in forest management, you can just simply look for a piece of wood that has an FSC label on it.”

So, labels. Julia says, works for her.

JW: “It’s going to be great, taking my boyfriend around the store and showing him all these cool things I can get to make our home improvements a little more cheap and environmentally-friendly.”

LG: “Alright remind me, go over this again. What am I supposed to be looking for?”

MG: “It’s very simple. If you’re looking for paint, look for GREENGUARD. For plumbing, WaterSense. For lumber, FSC, Forest Stewardship Council certified.”

LG: “That’s Matt Grocoff, Greenovation.TV. Thanks again, Matt.

MG: “Lester, it’s always a pleasure. Thank you.”

Millions of families had their heat
or electricity shut off this year.
Rebecca Williams reports that happened
even though government assistance
for energy bills doubled:

Record numbers of Americans are having trouble paying their heating or power bills.

Mark Wolfe is with the National Energy Assistance Directors’ Association. He represents the state agencies that help people pay their energy bills.

He says when families use up their allotment of energy assistance, things can get tough.

“It’s pretty awful – they go to payday lenders, pay high interest rates to get extra money, they borrow from relatives, they cut back on medicine, they turn the heat down to dangerous levels. These are families that’ve already gone from steak to chicken to rice. They don’t have a lot of choices.”

Four million homes had their heat or power turned off this year.


Wolfe says unless the economy improves next year, the number of families needing help with their bills could be even greater.

Some electric companies are working
to put smart meters on our homes.
They want to change how we use
electricity hour by hour. Eventually,
power companies will charge more
when demand for electricity is highest.
Mark Brush reports on a new study
that looks at how people are responding:

Connecticut Light and Power tested the smart grid on about 3,000 of it’s customers. Half of them residential and half of them business customers.

They found that people did respond to high rates during high periods of demand – such as from noon to eight pm.

Jessica Cain is with Connecticut Light & Power. She says there seems to be a limit to how much they’ll change. For example, doing laundry late at night seemed to be a non-starter.

“Doing your laundry after 8pm would be a barrier. And we heard that from customers, both from a residential customer side and then from a business customer side. We heard that changing their business hours outside of that twelve to eight window would be very difficult.”

The power company found the most energy was saved when the utility itself used the smart meter to shutdown things like air conditioners during periods of high demand.

The customers said they liked the “set it and forget it” approach – so long as they could override the system if they needed to.

More people are putting up solar
panels on their houses. But in
some places around the country,
solar panels are getting blocked
by homeowners’ associations. Mark
Brush has more:

It comes down to aesthetics for a lot of these associations. They have rules about how tall your grass can be, when trash cans can be set out, and what color your house can be.

Sometimes these associations just don’t like solar panels, or they worry they’ll be sued by neighbors.

Raymond Walker is a lawyer for Standard Renewable Energy. It’s a fast growing solar installation company in Texas. He says these restrictive rules can cost jobs and money.

“It doesn’t seem at first blush like it ought to be a big problem, in fact, you know, it seems like it might be sort of a silly issue, but we lost about $500,00 in installation money in 2008 because of this, and we’re projecting that we’ll lose about two million dollars this year.”

There are some state laws that say homeowners’ associations can’t stop the construction of solar panels, and now some legislators want to see a federal law passed.

A new study finds living near
a wind turbine does not have
a noticeable impact on the
value of your home. Rebecca
Williams has more:

Researchers looked at the sale prices of almost 7500 homes around the country over eleven years. The homes were as close as 800 feet to a turbine or as far as 10 miles away.

Ryan Wiser is a scientist at the Lawrence Berkeley National Laboratory. He’s an author of the report. He says being near a wind turbine did not have a widespread impact on property values.

“There may be still some sense that the aesthetics of a place has been impacted either positively or negatively and that may affect one’s impression of value, even if it doesn’t affect actual home sales prices.”

Wiser says they accounted for the housing bubble burst, and they still found that being close to a wind turbine did not affect how quickly a home sells.

Home improvement projects cost
a lot of money. Some environmentalists
have found a way to save some money,
conserve resources, and help other
people get into homes. Lester Graham
reports:

It seems like my friend Matt Grocoff with Greenovation TV is always working on a home improvement project. Not too long ago, he asked me to go with him to his favorite store. So we headed down the road where all the big box home improvement stores are in his hometown of Ann Arbor, Michigan, but that’s not where we ended up.

MG: “Just about anything I need, my first stop is always a re-use center. My favorite is, of course, the Habitat for Humanity ReStore. Today I’ve gotta find a– a, uh– what do you call them? A sander, a hand sander, a belt sander?”

Matt turned to Jackie Hermann who manages this ReStore. And she pulled a case from the shelf in back.

JH: “This absolutely beautiful Porter Cable professional random orbit sander with dust collection.”

MG: “This is gorgeous. This is exactly what I need. And how much is this?”

LG: “Looks like it’s never been used.”

MG: “Almost new condition. $35.00. And it’s used material that’s not going to a landfill or sitting in somebody’s basement not being used. And here I get to use it and save money. This is another one of the things where we can debunk the myth that going green costs more.”

Okay, so Matt got a good deal and it extends the useful life of a pretty good tool. But the idea is to raise money for Habitat for Humanity to help get people into homes, so I had to ask Jackie about that.

LG: “How much of that money actually goes to Habitat for Humanity and building houses for folks?”

JH: “We have a 12% administrative overhead, so 88-cents on every dollar into a habitat home.”

There are about 600 of these ReStores across the nation. The administrative overhead varies a bit from store to store, but the money raised at each store goes to homes in that store’s local area.

Jackie says, for her area, that’s meant a bit of a shift for Habitat for Humanity. You might have heard, in Michigan there are a lot of foreclosures.

JH: “We’re not building brand-new as much. We are buying foreclosed houses that are already existing in blighted neighborhoods, and we are rehabbing them and making it livable and improving the neighborhood.”

LG: “You’re recycling houses.”

JH: “We are! We’re recycling houses also. So, when Lowe’s, for instance, donated a large quantity of items, we kept a bunch aside for construction. They come and they look though and say what they can use, and then those items are set aside for them. And then as they need them, they use them.”

And anything left over is sold in the ReStore. It’s donations that make ReStore work. It might be overstock from places like Lowe’s or from local contractors. It could be people who are moving or retiring or just don’t need an appliance any longer. They might have extra cabinets, or carpeting, or a perfectly good sink they don’t need.

JH: “The proverbial kitchen sink. Lots and lots and lots of toilets. Light fixtures, flooring, doors, windows, fasteners.”

MG: “Lester, let me show you some of the stuff they’ve got here. My wife and I spent months looking for a really high-quality, affordable, high-efficiency, front-loading washer. This is a front-loading washer and dryer. (taps on appliance) In fact, this is the same model that we bought. We paid $600 for ours. Here, at the ReStore, it’s $200. And Jackie, how do we know that this works?”

JH: “Everything’s been tested. And, it’s guaranteed for two to three months – I’m really not picky about that.”

Some things are used, some are new. It all works.

Matt Grocoff with Greenovation.TV says it keeps stuff out of the landfill, it means perfectly good building materials and appliances for home improvement projects, saves resources, and raises money to help people get into a home.

MG: “It’s a win-win across the board.”

also generated a lot of controversy,

Samara Freemark reports
that legislation currently moving through
Congress would change that:

Hydrofracking involves pumping millions of gallons of water, sand, and chemicals a mile into the ground to break up rock and extract gas. But since 2005 the technique has been exempt from federal environmental legislation like the Clean Water Act and Safe Drinking Water Act.

Now some members of Congress have introduced a bill to restore federal oversight over fracking. Kate Sinding is with the Natural Resources Defense Council, which supports the bill.

“So what has been proposed is known as the FRAC act. And what that would do is restore regulatory authority over hydrolic fracturing which means we would have some federal standards about how to regulate this activity. And it would require the public disclosure of the fracturing fluids that are used in fracturing fluids.”

That’s an important point for fracking opponents, who say those chemicals have contaminated wells and groundwater across the nation.
