Shedding our Fossil Fuel Suit

Fossil fuels have leveraged human power and ingenuity to a remarkable degree. Their discovery and accelerating utilization utterly transformed lifestyles, achievements, and even how we perceive ourselves as a species.

Yet, one thing we know for certain about fossil fuels is that they are a finite resource on this planet—slowly developed in select locations over hundreds of millions of years and being used about a million times faster than the rate of production. We know that we have already consumed a sizable fraction of the initial inheritance: perhaps now halfway through the irreplaceable allotment of oil. So we know that this phase of the human adventure is a temporary one.

The quintessential graphic for conveying this idea is one I have used many times, because I believe it is the most important plot modern humans could possibly absorb. Human energy use has shot up in the last 150 years, and in the context of fossil fuels will plummet on a similar timescale, leaving—what, exactly?

fossil fuel usage is recent, fast, and will be over soon

The fossil fuel energy explosion that powers our current fireworks show is a momentary phenomenon that will be over in a historically short time.

Over timescales relevant to civilization (which began 10,000 years ago with agriculture and cities), plots of almost anything relating to human activity look like hockey sticks: population, agricultural output, industrial output, mined materials, deforestation, species extinctions, and so on [see this later post]. Many of these certainly correlate to population growth, but the per capita impacts also have shot up, compounding the human footprint to a frightening degree. At this point, humans and their livestock account for 96% of mammal mass on the planet, leaving a mere 4% for all wild animals (half of this from massive whales and other marine mammals). It’s not just a footprint any more: it’s a boot on the throat of the planet, leaving non-human life gasping and silently begging for even a little mercy. Is anybody getting video of this?

Almost all of this explosive impact can be traced to fossil fuels, which I have started visualizing as a suit donned by humans that has given us literal superpowers. What would we be without our fancy suit?

Peak Oil Perspective

Posted on by

It was by teaching a course on energy in 2004 that I first became aware of the enormous challenges facing our society this century. In preparing for the course, I was initially convinced that I would identify a sensible and obvious path forward involving energy from solar, wind, nuclear, geothermal, tides, waves, ocean currents, etc. Instead, I came out dismayed by the hardships or inadequacies on all fronts. The prospect of a global peak in oil production placed a timescale on the problem that was uncomfortably short. It took several exposures to peak oil for me to grasp the full potential of the phenomenon to transform our civilization, but eventually I was swayed by physical and quantitative arguments that I could not blithely wave off the problem—despite a somewhat unsettling fringe flavor to the story.

Aside from excursions here and there, Do the Math represents—in computer terms—a “core dump” of years of accumulated thoughts and analysis on energy, growth, and the largely unappreciated challenges we face on both short and long terms. During this queued process—with much more to come—I have made references to peak oil, but have refrained from a head-on treatment. As important as peak oil has been in motivating my quantitative exploration of life beyond fossil fuels, it seems overdue that I share my thoughts.
