This post is a part of the series An Acre of Sunshine.
I always wanted to own property in the countryside. I loved
the hiking, fishing, canoeing, and other related outdoor pursuits. But
there is something different when one is the owner, the land manager,
and if done right, the steward. When we relocated to Ottawa, the
Canadian capital, finding a place outside the city to call our own was
something that was at the top of the list. Within a year of
our arrival, we found our perfect spot - nearly one hundred and fifty
acres of field, forest, and wetland, spread across rolling hills and
nestled alongside a river. It felt quite wild to me, but they
called it a farm. It was little like the flat open farmland that I was used to seeing throughout my childhood in the Midwest, where fields run together and the only trees are often those just adjacent to farmsteads and along fencelines. On this property, there was no barn or silo, but rather a few modest hilly hayfields, and a forest where trees were cut
occasionally for lumber or firewood. When my wife and I had begun
looking for our countryside escape, we thought about what we wanted mostly in terms of lifestyle and recreation. But it is a farm, and we had become
farmers.
From the time we purchased the property, my mind was overflowing with the possibilities of what we could do there. Of course,
much of my attention was on all of the recreation that our family would
be doing, a broad swath of sports, including snowshoeing and cross country skiing
all winter, hiking and fishing the rest of the year, a bit of
deer and grouse hunting thrown in during the fall. But it was never just
about recreation, it was also about stewardship and sustainability,
taking proper care of a space, using it in the present, but preserving
it for the future. As much as possible, we also wanted to live lightly
on our new property, preserving the full range of flora and fauna that
are found there. A primary reason for choosing this particular property was
the natural aesthetic of the place, which we wished to preserve. Since I was a young child, I had dreamed of living out in the
wilderness, of living off the land. But as I grew to adulthood, I
realized that the sort of rugged independence where I would build a house by hand and grow all my own food was not the dream
that I was pursuing. I have no desire to be fully independent from the
rest of the world; people are social beings, and productive societies
always exist by allowing everyone to specialize, each to his own talents
and predilections, and then cooperate so that each person has their
needs met. We all need and want those goods and services that allow us
to survive and thrive. But we all share the same world, and we need to
make sure that we, combined, live in a way that is sustainable so that
our children and their children will be able to continue to prosper as
we do today.
Real sustainability isn't the same as simply conservation, and leaving all natural places alone. While true nature refuges are critically important, people also need to produce many goods from the land to support themselves. I felt that part of my
responsibility was to continue to keep this land productive, to help
provide for human needs as well as to be a wild and natural place. A
question kept coming back to me: Was our farm, in this rocky and hilly Canadian forest,
even capable of being productive enough to support my family and our needs? As I began to work through all of the possibilities, I
considered how it was possible to compare them; Should we grow trees or
corn? One way to answer these questions was to simply ask which one
would yield the highest dollar returns. This is certainly the typical way that farmers make their land-use decisions. While we wished to make a few
bucks, concerns of sustainability stayed at the fore, and our main incomes will always be off the farm. I then had an epiphany
about our land use planning. It wasn't the most original, but it is one
that is key to land management, and I'll share it with you: All farming
and most sustainable land use is the farming of sunlight, capturing some of those rays and
using the energy contained in them. One takes sunlight, and converts it
into maple trees or wheat, chickens or deer. So my realization meant
that the question that I was asking about providing for my family was
really a question about energy. I started to come around to thinking
about sustainable land use more broadly as being about energy; how much energy could we
capture and use? Was a farm like ours capable of producing enough
to support the energy-intensive modern lifestyle of my family? How much
energy does it really take to support a family anyway?
At the same
time as we were purchasing our property, we were also busy with
starting to design a house that we would build on a hilltop
overlooking the river. For years I had also been interested in
architecture, particularly green building practices and energy
efficiency, and so we decided to design from the start a place that
would be incredibly energy efficient. We received an extra push for
efficiency from the fact that our building site was so far from the
nearest powerlines that it would have cost a small fortune to run
power to our new home. Solar photovoltaics were going to be the
only reasonable way to provide electricity. Going with off-grid solar
almost automatically puts one in an energy conservation mind-set,
because for every extra light or computer you want to power, you need to
pony up more cash upfront to install more panels and batteries. Energy of all kinds
was going to be at a premium at this location, so we made decisions to
reduce use and keep all appliances and mechanical systems efficient. To reduce
heating needs, we took inspiration from several different green design
movements to incorporate passive solar design and superinsulation to our
home. All in all, we reduced by approximately 70% the amount of energy
that we will need to use in this home compared to standard construction. In
working with an architect and tradesmen of all kinds, I learned the
ins and outs of energy flows around and through a home, and in many
ways they really didn't seem so different from the energy flows involved
with land use (If you are interested, see my blog about that house here).
While working on both land use planning and
home design, I was consulting innumerable sources, on forestry, farming,
energy, architecture, and more. As written, each of these sources was aimed primarily at specialists in each field, those that wished to take
part in these practices. What wasn't there, and that I yearned for, were some of the threads that tied all of these concepts and practices
together. How did each of these fields relate to the human level, an
individual, a family? Again, I could see that in each, a common theme
of energy use was central to each of these endeavors. Sustainability
and renewable energy are tightly intertwined, and I was learning
enormous amounts about how these systems worked, and could see a place
for sharing this knowledge with others.
Herein lies the
heart of this story. I have explored the intersection of energy and land
use at a human level, and want to
share that story. This story is an investigation of energy,
renewable energy, a single source to walk through the basics of energy
use and energy production in a home and on the land. I want to tackle such
questions as; How do different uses of solar energy actually compare?
How do they measure up to fossil fuels or nuclear energy? How much land
do we actually need to support people sustainably? If we tried to go to an all renewable, all sustainable economy, could we do it while maintaining our current standard of living?
The lens I use to examine all
of these questions is our forested farm, looking at the
question of what we have already done and what we could do in the future. Hopefully, by
looking at these different choices on a small scale, in human terms,
ideas about energy will click for some people who have never really
understood, or perhaps never thought about, the energy that we use each
and every day.
A few disclaimers are needed, just to get
things started with clarity. First of all, with a story like this,
comparing different forms of land use, different types of energy storage
and conversion, a lot of numbers are going to be needed. Comparing land
use in terms of energy requires a lot of calculations based on the sorts of products
one could produce. At the same time, these things are complicated, and so it is extremely difficult to pin down those numbers precisely, there is always a range. I try to simplify everything down to rough estimates, to get a feel for the landscape without trying to get get complete precision. Second,
the economics of all of these choices are mostly left out - the incomes
that could be generated are important, and references to them are made,
but energy is the focus here, not dollars. In order to keep it
manageable, this is not meant to at all be a how-to manual for any of
the topics in it; materials like that are the sorts of sources that I
used to put together this story. Instead, it is meant to broadly educate
about energy and land use, to draw attention to the some of the considerations we ought to be focusing on, and realign the discussion
about sustainability to issues of energy - how we produce it, use it,
and how we can continue to have a high standard of living without destroying the world.
Though the numbers are important, there is a story to be told that doesn't depend on those numbers. Through all of the sections I put a less technical discussion at the beginning, and follow it up with a more in-depth numbers-based investigation.
