Our ancestors were using fire for cooking over a million years ago. This gave us an artifact to compensate for our mutant jaw muscles, which were not as strong as those of our fellow primates. Fire aided our masticatory ambitions as well as our gustatory needs by rendering previously inedible or toxic foods into a feast fit for a king.
With fire, we managed to squeak through the last ice age, and the climate that unfolded before us was like unto a Garden of Eden. Using fire to preserve food, martial game, fire clay and to render deep forest into the more open environment characteristic of the early Fertile Crescent, we began our journey through our species’ logistic growth curve.
Today, we are immersed in the products of fire. By using the products of fire to contain fire we developed cultural artifacts that are the product of temperatures and pressures previously unattainable by Earthly life. Metals, plastics, ceramics, glass; these material products pervade our modern world.
The materials we take from the living world rarely make it into our purview without being touched by fire. The cultural practices that allow a substantial minority of the Earth’s population to live largely free from parasites, malnutrition, and disease were born from fire. The only surcease our kind has known from the unrelenting labour of agriculture has come from ruthless exploitation of others’ lives or the power of fire to toil in our stead.
Fire is not a tender Muse, and our obeisance to her dictates have caused us to repeatedly burn all that we could find to burn. Our initial love affair with Fossil Oil arose from the rapid depletion of another over-exploited resource: Sperm Whales. While themselves the fourth choice, after having extinguished four other species in the North Atlantic, an oil extracted from their fat was the only oil for lanterns if you didn’t want to stoop to burning lard.
Everyone who lacked the mixed fortune of living near a gasworks was utterly dependent upon them for light. The first binary communications medium, the telegram, had dramatically shrunk the world; if you didn’t burn the midnight oil, the other guy would, and by the 1855 whale oil was going for the 2003 equivalent of over $1500 a barrel. The extraction of kerosene from fossil oil freed us from burning whale fat.
By the turn of the 20th century, internal combustion engines dramatically increased our appetite for oil; the newly developed spark engine delivered more horsepower but demanded a less viscous fuel than the rapeseed and peanut oils used in early diesel engines. By this time, ‘crude’ oil was already being distilled into different fractions, and a fraction that was slightly more viscous than kerosene was adopted for internal combustion engines.

Today transportation fuels dominate our consumption of oil, and in the largest markets it has surpassed the use of all other fossil fuels. We now sit perched somewhere near the peak of oil production, and the consequences of continued fossil fuel use will make the mere extermination of whales seem quaint.
Some hold out the hope that another energy supply will come to surpass oil, or more broadly combustion; Photovoltaic Solar, Nuclear, Wind, Hydroelectric and Geothermal sources have all been mooted. Using these sources will allow us to reduce our use of fossil fuels, particularly coal, as point sources. None can provide the portability, stability, and ease of use that has made oil the number one source of energy.
