The Power of One

Power bill

Power prices have climbed relentlessly over the past decade.

The usual justification is that the country needs more power and that the cost of generating this has increased (power stations are expensive to build and maintain). The population is growing and we’re using more electrical technology than ever before – although greater efficiency in lighting and heating products has helped offset some of this demand.

New Zealand’s total power use has doubled in the last 30 years. Various governments have taken differing views on the relative proportions that industrial, commercial and residential users should pay for the costs of generating and supplying electricity. So in the decade from 1982 to 1992 average residential power prices rose just 0.6 percent per year in real terms (above inflation) but increased 2.1 percent per year in the following decade. From 2003 to now, they’ve risen by almost 7 percent per year in real terms – that’s even excluding the latest GST rise.


And then I did some sleuthing, and found this.

Did you know?

  • A typical household of four people spends around $2,800 a year on energy, not including transport [1]
  • Electricity makes up more than 85% of the energy bill in an average house. Most of the remainder of the bill is gas [2]
  • The price of electricity increased 7.5% in the year between 2007 and 2008, and 41% in the five years between 2003 and 2008. [2]


[1] Statistics New Zealand, Household Economic Survey: Year ended 30 June 2007, 2007 (online).

[2] Ministry of Economic Development, 2008, Schedule of Domestic Electricity Prices: Updated to 15 November 2008, 2008 (online).


And then I pulled this up: Our power bill from March.

The average Kiwi home uses about 12,000 kilowatt hours (kWh) of electricity per year at a cost of about $2,800. That translates to about 1,000 kWh per month at a cost of $233. Looking at the bill above, we used 47 kWh at a cost of $22.92. We have been tracking our electricity use since we had the power switched on in November.

Many days we use less than 1 kWh, but our average is between 1 and 2 kWh. Including the line charge of 38.33 cents per day, we have paid less than $1 per day (at 25.7 cents per kWh) for the last 7 months. And for that 1 dollar we have renovated a house using LOTS of power tools. We also have a refrigerator, toaster, slow cooker, oven, mobile phone, computers, radio, electric jug, etc. The trick is we squeeze as much as possible out of that $1.

Regarding being eco, thrifty and hedging against rising energy costs, it only takes simple maths to convince oneself that this information regarding the rate of price rises from the above sources are frightening, especially for those on low incomes.
1) From 2003 to now, they’ve risen by almost 7 percent per year in real terms – that’s even excluding the latest GST rise.
2) The price of electricity increased 7.5% in the year between 2007 and 2008, and 41% in the five years between 2003 and 2008. [2]

These electricity rate rises outpace inflation and wage increases. If energy efficiency and conservation measures are not put in place by households, it will be impossible to keep up. Every dollar spent on improving energy efficiency will pay for itself many times over in savings, and will outperform any bank account or similar investment.
We are looking at saving about $2,500 per year from that average Kiwi household use of $2,800. With savings like those, our solar hot water ($3,900) and insulation ($3,100) will pay for itself right quick.

"The coldest house in New Zealand"

When we first bought this house we knew we were in for a lot of work.

But we were ready for it. We started putting on a new roof, replacing windows, insulating, etc. We held workshops and open houses to educate members of our community about passive solar design and eco-renovation.

At one of our first open houses a woman said, “I’ve been in this house before. I baby sat here once. This is the coldest house in New Zealand.”

Despite her ringing endorsement, we persevered. We added windows to the north and removed them from the south walls. We insulated more. We are building pelmets and hanging thermal drapes. We are draft-proofing.

This week while I was promoting the Science of Sustainability at Wanganui Intermediate School I asked the students in each class if they had turned on the heat in their homes yet this autumn. Nearly all students (and teachers) raised their hands. I smiled and said, “We have not had to turn on our heat yet, because the sun is heating our house.”

Peace and passive solar success, 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!

This is not my beautiful wife…

How art imitates life. Talking Heads version.
And you may find yourself in another part of the world

And you may find yourself in a beautiful house,

with a beautiful wife

And you may ask yourself, How do I work this?

And you may tell yourself, This is not my beautiful house!

And you may tell yourself, This is not my beautiful wife!

Letting the days go by/let the water hold me down

P.S. FYI: See this article in the New York Post last week.

Gathering Steam

The fifth monthly edition of the Wanganui Permaculture Gathering was held this week on May 18th (always the 3rd Wednesday) at the Whanganui Environment Base on Wicksteed Street.
The gathering is modeled after Permaculture Noosa’s monthly meetings held on Australia’s sunshine coast. They get upwards of 200 people at their meetings. I believe it is because of the simple format: 30 minutes of a mini-farmers’ market; 30 minutes of a guest speaker; and 30 minutes of news, announcements, etc. That’s it!
The model has worked well for us so far. Why not try it in your community? What have you got to lose?
This month’s speaker was Jonah Marinovich from Wanganui’s Green Bikes program.
Jonah, however, did not so much talk about Green Bikes, but about some interesting community activism projects he was involved with in Wellington. He provided an awesome story about creative, low budget resources access and (re)allocation.
We are tentatively looking for a speaker for the June 15th meeting and planning a Quiz Night fund-raiser for Green Bikes on July 20th. Please let us know if you can be a speaker or know of a venue to host the July Quiz Night.

Takin’ it to the Streets…er, Schools.

We are pleased to announce that the Eco-Thrifty Reno has busted out of Castlecliff all the way to Wanganui Intermediate School…

… and Wanganui High School.
At Wanganui Intermediate I am working with 18 classrooms to get the students thinking about using their own homes and sections as potential research projects for the upcoming science fair. The program is called, “The Science of Sustainability.”
At Wanganui High I am working with a senior level sustainability course to look at the Eco-Thrifty Renovation as a “sustainability initiative.” I have done two classroom presentations this week and tomorrow they come for a site visit.
If you know of schools, school districts, teachers or departments of education interested in high quality, practical, relevant sustainability education, please put them in contact with us at

Raising the Roof

National Public Radio told me this morning that the U.S. has surpassed its debt ceiling of 14.3 trillion dollars. And the most likely solution from Congress after some token bickering? Raise it. The unsustainability of that decision astounds me. It will not be long before the U.S. government will be selling public lands and national treasures to private entities as Greece is proceeding to do under pressure from lenders. (See previous two posts.)
Debt is dangerous.
I also heard on NPR this morning that student debt in the U.S. has surpassed credit card debt for the first time and will reach 1 trillion dollars this year. Again, astounding and unsustainable. As Mike Shedlock says, “What can’t be paid back won’t be.”
A degree in ethnomusicology with $98,000 (US) in loans?!?

Meanwhile at Arawa Place this week we have finished replacing our roof with no intensions of raising it anytime soon.

And, although the ceiling in our lounge sags a bit, it is now insulated. We like it that way and have no intensions of raising the ceiling either.

Peace, and pay-as-you-go, Estwing

Oilier, Greecier…

It’s been a long, busy week and will be another long, busy weekend. But in the spirit of making connections from the global to the local and from the unsustainable to the sustainable, I noticed that Greece and Oil and still in the news. This from Marketwatch, shows the top story for the day is, “Greece casts shadow over Street.” And in the table on the right it shows stocks down but oil up.
And this next headline from the Wall Street Journal should make sense to anyone who’s been paying attention to world events.

And so, here on Arawa Place we are trying to protect ourselves from the volatile effects of forces outside of our community. And we’re cutting our carbon footprint in the process.

We are renovating an old house for energy efficiency and growing as much of our own food as we can. And we’re sharing the experience with others. Today is an open house.
Drop by and check it out.
Peace, Estwing

Oil and Greece

I wrote about these topics a year ago on another blog, surf2survive, but they just don’t seem to go away. We are a year on from the Greece bailout and in the midst of more volatile oil price gyrations: up nearly $6 U.S. today.

Meanwhile, Greece celebrates it’s one year anniversary by preparing to sell state assets to pay back foolish German, French, British and U.S. banks who unwisely invested there chasing unrealistic returns.

I bring up these issues today because each one has implications for be eco-thrifty. First lets’ take a look at Greece. Greece is all about living beyond one’s means, going into debt, paying high interest rates, and then ending up with a liquidation sale. This, of course, is not unique to Greece. The pattern is repeated across the entire planet from Athens to Zimbabwe. In the beginning, living beyond one’s means and going into debt appears to be thrifty because it costs very little to do so. But in the long run, debt is not thrifty. As the Greeks, Irish and Portuguese know, it can be extremely expensive.

Now oil. Put simply, oil prices will remain volatile for the foreseeable future while trending ever upwards to new record highs. This is simple supply and demand. As supplies run short and demand grows, prices rise. But extremely high prices cause “demand destruction” which sends economies into recession which brings prices down again temporarily. And then the pattern is repeated. To put things into perspective, here is a graph of oil production over a 2500 year period.

Failure to invest in energy-saving products is also not thrifty. But again, in the short run may appear to be. For example, incandescent light bulbs are cheaper in the shop than compact flourescent bulbs. But in the long run they are much more expensive to operate. This is not thrifty at all. Nor eco for that matter.
So what do Greece and oil have in common? They both show us clearly that short-term thinking is expensive in the long run. Here at the ECO School we recognize that debt is dangerous. Inefficiency is dangerous. Being eco-thrifty means living within your means while investing everything you can into energy efficiency without going into debt. For example, we are looking at a 7% to 10% return on our solar hot water system.
Money where my mouth is: solar hot water, north-facing glazing, super-insulation.
We paid $3,900 N.Z. cash for it installed. Had we borrowed that money, most of our savings would go to the bank. I have said it before, the best way that governments (if they are serious) can promote citizen investment in renewable energy and energy efficiency is to offer no-interest loans. Otherwise, we just continue to make bankers richer.
And that’s all I’ve got to say about that…for today, Estwing


As farmland in the US is transformed into lakes and heathlands in England are transformed into charcoal, I thought we might highlight some positive transformations on Arawa Place. Recognize this image?

Now it looks like this.

And that old framing became…

…the back steps.

And some may recall an early picture of our lovely lounge…

…which now looks like this.

We removed all of the rotten studs and re-framed the entire wall, put in a new (second hand) window, and built a pelmet from a beautiful piece of native wood which had been a barge board on the exterior.

And with the curtains drawn.

Ah, the memories.

We’ve also started to transform some of the old rusticated weather boards…

…into pelmets. I find this one particularly attractive.

Ah, too many more images to show in one post. We’ll post more soon. Until then, please go out and transform your world for the better.

Peace, and change we can believe in, Estwing
