Thanksgiving week in America is a time of celebration of family, and of giving thanks. I feel very privileged to live at a time and in a place that is so entitled in terms of resources, security, culture, and opportunities. One way that I can attempt to live up to that privilege is through this blog, in ways that attempt to change the culture for the better for future generations. And one of the best ways to change culture is to make the alternative more fun. Bike touring is one of the low-energy habits that has become habit-forming for us, as it is inexpensive, it allows us to get out into nature and into new places that might be difficult to get to otherwise.
previous trip to Nome Alaska
One photo that has been passed around from this blog is a surprising one. It is a photo of a previous bike trip to Salmon Lake, near Nome Alaska, on a tour with friends several years ago. This photo shows up repeatedly on my website statistics page as having been passed around all over the world–why is that? Are other people planning trips to Nome? Is it the beauty of the place, and the wide-open vistas of the arctic tundra? For Thanksgiving, I would like to share a photo essay of that trip, in appreciation of Alaska’s unspoiled wilderness. I give thanks for having access to one of the most amazing, pristine, unspoiled wildernesses in the world. Continue reading

There have been a flurry of public conversations recently about the importance of protecting the biosphere. We are paying more attention to the environment again, after forty years of neglect. And many people are finding this website after googling a surprising question, “Is ecology good for economies?”
There is a growing recognition of the importance of the environment, but there is still a disconnect in understanding the link between environment and economy, and inertia about how to begin to make changes we need to make. How do we convert the basic cultural assumption or value that what is good for us is good for the world? How do our values and ethics shape our culture for adaptation to a future of energy descent? Are values more important during times of scarcity, and how must our values change if we are to survive?
I recently read Holmgren’s 2002 book, Permaculture; Principles and Pathways beyond Sustainability. The developing science of permaculture applies systems ecology principles to a new way of living—a permanent culture that honors the environment. Permaculture respects our energetic limits, as a means of restoring the environment while adapting to our future of less energy. Holmgren begins his book appropriately with a description of the three ethical principles of permaculture: care for the earth, care for people, and fair share. The second and third principles are derived from the first, which is primary. I was going to write a general review of Holmgren’s book, but then realized that I needed to spend an entire post discussing his first ethical principle of Care for the Earth. The review will have to wait until later.
Holmgren recognizes the increasing importance of environmental protection during the collapse of a society in overshoot. As the culture evolves to fit a lower energy pattern, societies that survive will be those that care for and protect their ecosystems. Too many people with too much technology will put extra pressures on the biosphere. Our growth-oriented values, ethics, and religion will have to evolve over time if we are to survive. What might that look like?

This is the third and final post in a series revisiting HT Odum’s classic Ambio paper on the 3Es (Ambio, 1973). The article was republished in Mother Earth News, and the reprint is still available online through Minnesotans for Sustainability. The first 15 points are covered in part one and part two of the post series. The final five points, 16-20 of the Ambio paper, are extracted and quoted below, with updated explanations. In this final section of the paper, Odum described relative energy availability during stages of growth and descent, and recommended policies for energy descent. Continue reading

Why is the movie Gravity so scary to some people, and why are people in both sciences and the humanities discussing the movie in a focused fashion, picking at its details? I would argue that the movie Gravity serves as a metaphor for a shift in world views about what is possible and sustainable in terms of our high-tech society. The discussion here of space travel allows me to continue my fall theme of illustrating emergy principles using science-fiction blockbuster movies. The movie also provides an opportunity to illustrate the emergy basis of space travel, and to suggest a metaphor between the failures of technology in the movie and the unsustainability of our modern civilization. Spoiler alert: If you haven’t seen the movie Gravity yet, there are spoilers ahead. Continue reading

This is part two of a three-part series revisiting HT Odum’s classic Ambio paper on the 3Es, which was written 40 years ago for a special issue of the Royal Swedish Academy of Science’s Energy in Society issue (Ambio, 1973). The article was republished in Mother Earth News, and the reprint is still available online through Minnesotans for Sustainability. The first 10 points are covered in part one of the post series. Points 11-15 of the Ambio paper are extracted and quoted below; in this section of the paper Odum described the not-yet named field of ecological engineering, as well as energy quality (transformity), and the net energy of solar and nuclear energy.

We must understand the concept of net energy in order to see the underlying energetic basis for society. Yet net energy is often misunderstood, typically through optimistic measures of valuation that do not address the hidden inputs. Perhaps HT Odum’s clearest, simplest, most understandable paper on the topic was written 40 years ago, in a special issue of the Royal Swedish Academy of Science’s Energy in Society issue of Ambio (1973). The article was republished in Mother Earth News, still available online through Minnesotans for Sustainability. The paper remains as relevant and fundamental to the arguments for net energy today as it did 40 years ago. Each time I read the paper, I find new meaning from it. Perhaps it is time to revisit the principles quoted below from the paper, to update the terms and give modern examples of the interrelationships between the 3Es of energy, ecology, and economics. Some of the terminology and accounting methods have been refined over time, but the general principles remain unchanged–principles that are essential to the energy dialogue. Continue reading

The more freedom we enjoy, the greater the responsibility we bear, toward others as well as ourselves. –Oscar Arias Sanchez
It is easy to get distracted when the world appears to be falling down around our heads. This week, the Emergist reports that he has gotten waylaid by intrusions at the personal scale, and relates those intrusions back to the principles of emergy and transformity. Here’s a snippet below from his blog this week about the transformity of his education, his feelings about his competing needs of parenting at the personal scale, and the urge to give to actions at the larger scale, and the relative value and costs of education in our society. The post is warm, funny, and something that I’ve been thinking about this week, too. Go read it, please, and I’ll wait right here while you do.
The Emergist Attacked by Two Toddlers
This blog has gone quiet for sometime, not that I haven’t had anymore topics to blog about, but because my oldest toddler has learned to turn off the computer. I actually have two posts fully thought out and half written. Further complicating the process is that the older one grabs the tip of my nose whenever he wants my attention, which is all the time, while his sister sneak attacks by smearing saliva on the screen with her hands. This all significantly ups the ante to write anything. Continue reading
