Memories

I was reminded recently that I have now spent three full years living and studying in New Zealand. I came to pursue PhD research in permaculture education at the University of Waikato in Hamilton. Before I enrolled in December, 2008, Dani and I spent 3 months house sitting in Wanganui. We liked the city and our friends here so much that after 2 years in the Hamilton area (2009 & 2010), we moved back to Wanganui and started this project while I write my dissertation. But those aren't the memories I'm talking about.

Just before flying into Auckland in June, 2008, I just missed my 15 minutes of fame back in New England. As I was sitting in the LA airport waiting to catch my connecting flight, I got an email from a TV news reporter from Boston. He wanted to do a story on my farm based on a recently published article in the Concord Monitor.


With gas at $4 per gallon, most people in New Hampshire can feel their wallets draining along with their car tanks. Not Nelson Lebo. He doesn't have a car. He's not worried about the cost of home heating oil either. And soaring food prices? Not much of a problem.

Lebo, 40, lives in a 1782 farmhouse in the woods of Andover that he has dubbed Pedal Power Farm. He heats it with wood cut from the property. He gets around on a bicycle. He grows much of his own food and buys locally otherwise. He gets his electricity from solar panels.

Lebo is no typical homesteader, content to stay tucked away in the woods, living off his land. He thinks he has ideas the rest of us could use. And he's ready to share them.

"I've been living in a post-petroleum world for the last 18 years," he said. "Everyone else is going to start living in a post-petroleum world next year."

Lebo has been a fixture in Andover since he was hired to run Proctor Academy's environmental program in 1991. He stopped working at the private school last year because of a herniated disk, but he still manages the organic gardens there. He was a part-time dorm parent this year.

But his teaching days are far from over. Let Lebo talk, and he will engage you for hours - he verges on ranting - about energy policy, American consumerism and the design principles around which he has built his life. One thing you won't hear much of is a holier-than-thou attitude.

He said he doesn't want to make people feel guilty about how they live. (He pointed out that he wears his hair in a crew cut and used to coach football, evidence of his own mainstream credibility.) He wants to encourage people to live differently. That, he said, is his "duty and obligation."

He and girlfriend Dani Lejnieks are moving

to New Zealand this summer, where Lebo will pursue a doctorate in environmental education, looking at how to apply permaculture principles - which say that human societies can be designed to mimic natural systems - to education.

Lebo thinks people should have less of an impact on the Earth as they become better educated. The way he sees it, most people become bigger consumers as they become bigger earners.

During his last few weeks in Andover, Lebo has been holding seminars at the farm, inviting a few people at a time to see how he lives. He has gone to some attendees' homes afterward, charging $40 per hour, to help them find ways to conserve energy. Some of his clients have been focused on living greener. Others want to save money.

Lebo said he used to call himself an environmentalist.

"Now I tell people I'm an economist," he said. "And not only that, I'm a conservative economist."

After years of being perceived as "just the kook at the end of the road," he said, his ideas - his way of living - are in high demand.

"It feels like my whole life has come to this moment," he said.

A 'lazy farmer'

Modern society has been designed around fossil fuels, Lebo said as he stood in front of his home on a recent sunny afternoon. But those fuels are running out.

"We, as a culture, will look back in 100 years and curse the designers," he said.

A moment earlier, he was praising one designer: the man who built his Old College Road home 226 years ago. He noted that the house, which he bought eight years ago, faces southeast, so the first rays of morning sun hit the front windows. The chimney in the center of the Cape-style home heats the whole house and is insulated from the cold.

The road in from Route 11 climbs a hill past several large, regal Victorian homes and sweeping green fields. It turns to dirt and narrows once and then twice, becoming bumpy and dark under the thick canopy of trees. The road crests a hill and continues into the small valley where the farm sits.

Story continues if you are interested: http://www.concordmonitor.com/article/post-petroleum-world?CSAuthResp=%3Asession%3ACSUserId%7CCSGroupId%3Aapproved%3ABA4A9537C4BF4594E11F4B09D8217743&CSUserId=94&CSGroupId=1

It is not 100% accurate, but it gives the idea of what my farm was all about.

Act Locally, Share Globally

I am a natural skeptic about new technology. I am not an "early adopter." I am more Amish in my approach - carefully weighing the costs and benefits before choosing what is appropriate. The technologies we've chosen to embrace for this project have well-documented results for return-on-investment in terms of energy savings. Examples are insulation and solar hot water.


Education also embraces certain technologies. And naturally, I am skeptical about those as well. It took me years to appreciate the power of blogs and podcasts. But now I am sold on their educational value. One of my favorite podcasts is called Two Beers with Steve.


I have done a number of interviews with him in the past, but this one is designed to coincide with my do-dig garden series: Part 1, Part 2, Part 3.


While I remain skeptical about much of the use of the internet, I think it has been a great help to us sharing the success of this project with a world wide audience. Our goal is to demonstrate that being green is not expensive. On the contrary, not being green is expensive! We enjoy a high quality of life with very low energy and food bills, and we are actively involved in making our local community more sustainable. Some of our experiences may be considered useful by someone on the other side of the planet. The web allows us to share our story with them with a very low carbon footprint.

So as the environmental movement evolves, I propose the next stage of evolution involves acting locally and sharing globally. Governments and corporations won't do it for us. We need to help one another learn how to be green and save some green.

Intersections

I reckon life is all about finding balance. And because we live in a dynamic world, the balance point is always changing. On this project we are looking for balance not only between eco and thrifty, but also factoring in the New Zealand building code and the potential for wide applicability across society and across the world. In other words, we are looking for the intersection of eco, thrifty, legal, replicable, beautiful and attractive to people other than already committed Greenies.


To my knowledge this is a unique endeavor. This project represents an everyman's/woman's approach to permaculture. There are lots of examples of eco-villages and perma-farms and expensive bespoke eco-homes. But in the foreseeable future, the vast majority of people will never live in such places. Most people in OECD nations live in places like this.


Well, much nicer than this actually. But we did not want to be accused of cherry-picking.


In response to Richard's comment on the last post, I'll give an example of the intersection mentioned above using insulation. Pink Batts are widely available, recognized by almost everyone, cost-effective, meet the NZ building code and contain up to 80% recycled content. Meeting (and exceeding) the NZ building code is essential to this project. So the options of insulation included Pink Batts, polypropylene batts, and wool batts. (We did not consider blown in cellulose too closely because we wanted to do the job ourselves to ensure quality installation and to keep costs down.) Polypro batts are made from recycled plastic and the wool batts are made from...wool. Both are more expensive and less available than Pink Batts.

Some people like polypro batts because they are so soft and easy to handle. But in terms of insulation, handling should be (!) a one off. I do not mind handling Pink Batts. Once they are installed, I don't plan to touch them ever again.

Some people claim that wool batts are the most eco option possible. I question that thinking. Have you seen the unsustainable ways sheep are grown in NZ? A holistic look at the ecological footprint of wool batts must include soil erosion, herbicides, and nitrogen fertilizers. Some might argue that the ecology, soil health and water health of NZ would be much better off with fewer sheep.


In the end, the insulation intersection for this time and place and the goals of this project was Pink Batts. For the equivalent cost of polypro or wool we were able to exceed the building code at a higher r-value. In other words, we have a warmer house at the same cost. By using an innovative installation technique (see Bridge to Nowhere), we reap the benefits and can share this under-utilized approach with others to replicate from Auckland to Alberta.

Still the One

We have had an amazing run of mild weather this autumn and early winter. Even up through Matariki - the winter solstice (fewest hours of sunlight for the year) - we have not needed any supplemental (electric or otherwise) heating for hot water or our living space. This has allowed us to keep our electricity use around one kilowatt hour per day for the last eight months. Our last bill was remarkably low. We used only 23 kilowatt hours in 30 days.


$15.72 includes a 38 cents/day line charge.

But those "cheap as chips" power bills are likely to hibernate until September, as we face two cold months ahead, and most immediately cool, cloudy weather and rain for the next 10 days. But I thought I'd share some of the best approaches we've chosen to save energy and money. From big picture to detail, they include:

Passive solar design: Increased glazing on the north side (toward the equator) for free heating.

(Morning photo: Drapes are still closed.)

Insulation: Holds that heat in at night.

Fiberglass insulation has up to 80% recycled content and is affordable.

Thermal drapes and pelmets: This is another form of insulation that happens to open and close daily. Mindfulness makes these much cheaper than double-glazing if you are conscientious about opening and closing them at appropriate times.

Pelmet is an old weather board from the exterior. (Ripped to 150mm and inverted.) Will be painted white to look like a crown molding.

Solar hot water: Electric water heating is one of the biggest additions to a power bill.

One of the best investments I've ever made. Thanks Allen!

Under-the-bench-fridge: Our refrigerator sips power while many others gulp it.

Small is beautiful! Big enough if you keep yourself organized.

Compact flourescent light bulbs: This hardly needs to be said, but CFLs use 1/4 the power of incandescent bulbs for the same amount of lighting.

Old reliable. I'm looking at LEDs, but the quality has to go up and price down.


We use heaps of other strategies for saving power, but those will be highlighted another day. Which of these can you implement in your home? What other great energy saving strategies do you employ?

Oh, the sun just came out. Gotta go open the drapes... - Estwing

The sad fact...

I'm sad because my beautiful wife has become stranded in Sydney on her way from New York to Wellington because of a Chilean volcano. She has been there for three days and it looks like at least one more. They stamped her passport "Indefinite." (Yesterday she went to a wildlife park and hugged a Koala.) But I know this sadness will pass.

This sadness, however, is another story.


Before my wife became stranded in Oz, I used to spend my idle hours (between dissertation writing and eco-renovation) talking with her. But these days I fill those hours reading blogs. One of my favorite is James Howard Kunstler's weekly contribution. Not only is the post a good read, but the comments section is equally insightful and entertaining. The image above is from the comments section quoting JHK, "The sad fact is we don't want to go where history wants to take us: to a smaller human imprint on the planet, with all that implies."



As an environmental educator for over 20 years, this sad fact is...a very sad fact. I for one, do want to go there, but I appear to be in the minority. The next comment in the thread reads: "Best, I think, to choose poverty before poverty chooses you." Indeed, I have been living below the poverty level in the USA and NZ for over a decade - often below half the poverty level as measured by income and expenditure. And during that time I have lived a rich, full life in beautiful places with healthy food and friendly people. My lovely wife, god bless her, has agreed to live this way too.


And we have fun doing it!


But there is a big difference between voluntary poverty and involuntary poverty. For us it is a mindful endeavor where we are simultaneously saving money, saving resources, and reducing waste. It is win-win-win for us, our bank balance and the Earth. That is why it is so sad that most people refuse to voluntarily shrink their ecological footprint. And now, from what I can observe, it is being forced on many of them by: high energy prices, high food prices, high personal debt, high municipal debt, high national debt, austerity measures, unemployment, population growth, etc.

I read a great blog yesterday talking about how the "Baby Boomers" lived far beyond their means during the real estate bubble (house = ATM) and are now having to postpone retirement because of the fall in house prices and the stock market crash (not to mention, gulp, the coming under-funded pension disaster). Forgive me, but I have no sympathy.

Living beyond your means = Destroying the planet on credit

To me, this is another sad fact. :(

Peace and poverty! Estwing

Permaculture Education in Wanganui Schools

After a great deal of effort from the Sustainable Whanganui Trust and we of The ECO School, permaculture education is reaching Wanganui schools.


A recently completed project with Wanganui High School used the Eco-Thrifty Renovation with senior students in a Level 3 sustainability course. The project was used as an example of a "sustainability initiative" for the students to assess on its merits. Two class meetings at the school were followed by a site visit. The project received much praise from students and teacher alike. The teacher said he would definitely get his Level 2 class out for a site visit.




The current project - The Science of Sustainability - at Wanganui Intermediate School involves over 700 students. In coordination with the school's science teacher, The ECO School has designed a programme to get students excited about the upcoming science fair through highlighting the science - physics, biology, chemistry - of a permaculture installation: The Eco-Thrifty Renovation. The scientific topics highlighted include passive solar design, solar cookers, rocket stoves, insulation, thermal drapes, compost, aerated compost teas, organic food production and various aspects of bicycling. Response has been excellent so far.


We've also had meetings with primary school teachers, but term 1 has proved a difficult time to ask them to take on anything new. We continue to meet with primary schools as term 2 appears more favorable regarding work load. Funding for these programmes comes from Wanganui District Council and is administered by Sustainable Whanganui. Thank you!

Down-Sizing

The south winds are blowing now, and even the insects have come in from the cold.

Praying for warmth.

When we bought the cheapest house in Wanganui, we knew we were getting a lot of space (110 square meters) for the money (less than a Ford F-150), but that NZ villas are notoriously cold and drafty.

Yes, this was our house in October.

A large house with high ceilings is a great asset for half of the year, but now that the equinox is behind us and we're closing in on the winter solstice, the amount of indoor space becomes a liability. So what I've been doing this week is cutting our losses. Heat loss, that is.

Yes, this was also our house in October.

While I've written about insulation and draft-proofing in previous posts, I have not yet addressed one of the simplest and most elegant forms of energy conservation in a home: shrinking it. I learned and lived this in Ladakh during the winter of 2006.


Ladakhis have big, beautiful houses, but they live in a desert at 3000 meters (9000 feet).


Traditional building in Ladakh was relatively cheap because houses were made mostly of earth and straw. Labor was cheap because your family and neighbors built the house with you.


But because of the cold climate, the entire house was used for less than half of the year. Fuel (dung or wood) is scarce in Ladakh, so during the winters the entire family lived in one room: the kitchen. Cooking also heated the living space while the rest of the house literally froze. Both eco and thrifty. Right on!


While we won't be restricting ourselves to the kitchen just yet, we have cut the size of our interior living space by 40 percent for the winter. Here's how:

Step 1: Frame a doorway in the central hall.

Step 2: Carefully install door purchased for $5 at local auction.

Step 3: Use leftover GIB around frame.

All that remains for step 4 is to paint and put up the trim. Step 5: curtains.

Note that we have cut off the south (poleward) side while we have increased solar gain on the north (toward the equator) side. The two large bedrooms on the south side where our interns John and Amy stayed over the summer are now secure storage for surf boards, bicycles and tools. These rooms will buffer our living space from the cold southern winds and provide dead air space (insulation). Also, they're a great space to store our great pumpkin harvest.


Come spring, we'll open the door again.

Fossil Fuel Free

As the sound of lawn mowers ringing out across neighborhoods wanes in the southern hemisphere and waxes in the northern, I cannot help but to ask...why?



Why burn limited fossil fuels manicuring a show piece?

Why buy and maintain an expensive, loud, polluting machine?

Why pay $2.10 per litre ($3.60 per gallon in the US) to run that machine?

Why contribute further carbon dioxide to an already overwhelmed atmosphere?

Why spend hours on land care that yields no food?


Problems: Global food prices are at a record high and rising. Oil has been above $100 per barrel for weeks and rose $3 today on increased concerns on the Middle East and North Africa.


Solution: Being "eco-thrifty" means going green and saving money. We use no oil to maintain our 700 square meter section using the following low-maintenance/high productivity techniques.


Growing Food



Once a weedy lawn, now a productive garden and burgeoning food forest.


Tractoring Ducks



Ducks eat grass and turn it into eggs, flesh and fertilizer.


Scything



Interns Amy and John learning how to harvest carbon-neutral mulch.


Please people. Stop the mowing madness! For the good of your wallet and the planet.
