I’ll cheat on my bi-weekly posting plan and slip in this podcast conversation between Chris Martenson and myself, covering many of the topics I have written about in the last year.
If you don’t have 45 minutes, and are a faster reader than I am, a transcript is also available—mercifully leaving out many utterances of “um” and “you know” (which is all I seem to hear when I listen to a recording of myself). The original source and surrounding intro/write-up can be found on the Chris Martenson website.
Putting on my astronomer hat, as one whose main research focus involves measuring the distance between the Earth and Moon, I feel compelled to “speak out” about the “supermoon” hype that crops up periodically.
Last night’s full moon was touted to be a “supermoon”—larger than normal. As a result, many folks made it a point to watch the Moon rise. I love the fact that people are paying attention to the Moon, getting outside, and enjoying the serene experience of watching the Moon creep over the horizon. What I don’t like is that the hype leads to an overall sense of disappointment in many. Is the campaign a net positive, or a net negative? I don’t know.
In this post, we’ll look at the numbers and see just how special the supermoon is.
So far on Do the Math, I’ve put out a lot of negative energy—whatever that means. Topics have often focused on what we can’t do, or at least on the failings or difficulties of various ambitious plans. We can’t expect indefinite growth—whether in energy, population, or even growth of the economic variety. It is not obvious how we maintain our current standard of living once fossil fuels begin their inexorable decline this century. And as I’ve argued before, achieving a steady-state future implies approximate equity among the peoples of the Earth, so that maintaining today’s global energy consumption translates to living at one-fifth the power currently enjoyed in the U.S.
In this post, I offer a rosy vision for what I think we could accomplish in the near term to maximize our chances of coming out shiny and happy on the tail end of the fossil fuel saga. I’m no visionary, and this exercise represents a stretch for a physicist. But at least I can sketch a low-risk, physically viable route to the future. I can—in part—vouch for its physical viability based on my own dramatic reductions in energy footprint. I cannot vouch for the realism of the overall scheme. It’s a dream and a hope—a fool’s hope, really—and very, very far from a prediction or a blueprint. I’ve closed all the exits to get your attention. Now we’ll start looking at ways to nose out of our box in a safe and satisfying way.
When I first approached the topic of societal energy in 2004, I became aware for the first time that our energy future was not in the bag, and proceeded to explore alternative after alternative to judge the viability and potential pitfalls of various options. I have retraced my steps in Do the Math posts, exposing the scales at which different energy sources might contribute, and the practical complexities involved. My spooky campfire version of the story, a la Tolkien: The Way is Shut.
Alright, I’m overstating things a bit. The good news is that there do exist energy flows and sources that qualify as abundant or at least potent. However, many of the alternatives represent ways to produce electricity, which applies only to about one-third of our current energy demand. The immediate threat is therefore the short term liquid fuels crunch we will see when the global petroleum decline commences within the decade.
In this post, I will reflect on the lessons we learn after having characterized the various alternatives to fossil fuels. There will still be some tidying-up to do on energy alternatives not treated thus far, but by and large the nature of content on Do the Math is about to pivot toward addressing the question “What can we do now?” In some sense, a common thread so far has been: “easier said than done,” or “don’t count on that technology saving our bacon.” I’ve closed all the exits to get your attention. We’re boxed in. Okay, the exits aren’t really closed: they’re just not as wide open as they would need to be for me to be complacent. So now we’ll start looking at ways to nose out of our box in a safe and satisfying way.
Kids these days. When I was a lad, tantrums were redressed with a spanking. Heck, spankings (at school) were answered by further spanking (at home). In polite company, we might apply the euphemism “attitude adjustment” to mask the unpleasant image of a bawling kid bent over the knee getting red in the tail. I’m not going to wade into the issue of whether or not such treatment is the most effective way to shape responsible adults, but I will say that I think our society needs some sort of attitude adjustment when it comes to expectations of our future. I’ll take a pause from the renewable energy juggernaut recently featured on Do the Math and offer some seasonal scolding. Think of it as my “airing of grievances” component of Festivus: “a holiday for the rest-of-us,” as introduced on Seinfeld.
What? Don’t know what bunkty means? Now you know how I feel about the word “sustainable.” My paper towels separate into smaller segments than they once did. It’s sustainable! These potato chips arrive in a box that says SUSTAINABLE in big letters on the side. I’m eating green! When I’m in a hotel, I hang the towel back up rather than throw it on the floor (would I ever do this anyway?) and the placard says I’m being sustainable. Can it be that easy? I claim that not one among our host of 7 billion really knows what our world would look like if we lived in a truly sustainable fashion. Let’s try to come to terms with what it might mean.
I think most would agree that the rapid depletion we currently witness in natural resources and services, climate stability, water availability, soil quality, and fisheries—to name a few—suggests that we do not live sustainably at present. We can not expect to keep up our current practices with 7 billion people in this world without some major changes.
Yesterday at about 15:40 local time, San Diego lost power—along with many other parts of Southern California, Arizona, and Mexico. Our power was out for 11 hours. The experience was fascinating for me, because it changes the rules of the game suddenly, and exposes certain fragilities in our system. This is a brief account of what I learned from the experience.
