When Long Cycles and Depletions Intersect (May 12, 2008)
If I had to summarize our plight, I would plot it thusly: The fourway intersection of a long financial cycle's nadir, a rising peak of geopolitical instability and the depletions of fossil fuels and other non-cyclical resources: sealife, soil, water, species, rain forests, etc.
Many of you are familiar with "long-wave" cycle analysis; one insightful financial cycle was identified by the Russian economist Kondratieff. Here is a depiction of the cycle, which maps a 60-70 year long cycle of credit expansion and contraction:
Depletions are not cyclical. Stuff which gets used up/killed off doesn't regenerate. Petroleum is in a depletion end-game depicted here in the classic Hubbert's Peak:
A number of other things don't regenerate, at least not within human lifespans or perhaps ever: ground water, rain forests (a monoculture tree farm is not a rain forest), species which are ground down to extinction, even soil. There is a continent-sized area of floating plastic in the North Pacific which will not disappear for a long time because plastic degrades very slowly. We can assume the area is only growing in size and density of waste.
A preponderence of evidence suggest that much of the financially valuable sealife on Earth is in essentially terminal decline due to overfishing and habitat destruction. If a few wild tuna survive, we cannot say the species is extinct, but as a "harvestable commodity" tuna will be depleted.
Uranium and other metals will contiue to exist, but not in financially viable concentrations. The energy required to extract them will exceed their value. At some point this may well be true of oil. It's still there in small pockets, but it takes more energy to extract it than it contains.
Geopolitically, two powerful long-term constraints on ethnic, tribal and regional conflict have dissolved: post-colonialism and the Cold War. Colonialism is simply a modern term for conquering or extending control ("Hegemony") over other lands.
When Tibet expanded into China in 763 A.D., it was imperialistic and colonial; when China conquered Vietnam around 1000 A.D., it too was imperialistic and colonial. When Islam conquered Spain, it was imperialistic and colonial; the point is simply that Western expansion is not a Western invention, and inventing a new word does not make "hegemony" or conquering other lands a new phenomenon.
Trick question note: Many Chinese become visibly upset when it is said that Tibet is not part of China. If you are ever in such a debate, just ask the Chinese person: "then shall we go back to the borders of 763?" He or she will undoubtedly agree, confident that China always ruled Tibet; then you can say, "Excellent. Tibet controlled Xian, capital of China in 763, and all the land from Lhasa to Xian." It is a historical fact that will give them a new perspective on the plasticity of borders and the fluidity over history of just who ruled whom.
Colonial empires rather naturally tend to suppress ethnic and regional conflicts (not to mention rebellions and uprisings) as bad for business, and so colonies must simmer in seething resentment for decades or even centuries. Once the colonial overlords have been overthrown/evicted, the first breath of glorious freedom is quickly followed by the renewal of old hatreds, blood feuds and ethnic/religious strife.
The arbitrary order imposed on Africa, the Mideast and Africa by the British Empire and wannabe Western imperialistic powers in the 19th and early 20th centuries has fragmented along much older ethnic, tribal and religious lines.
Just as the colonial hegemonies were overthrown after World War II, launching the post-colonial era, the Cold War between the USSR and the USA arose to impose a new series of alliances and hegemonies over virtually all nation-states.
The Cold War was actively hot for decades: the Korean War, the Berlin Wall and airlift, the Cuban Missile Crisis, Vietnam, the Prague Spring uprising in 1968, Afganistan in 1989, etc. Nonetheless, in 1972 the Cold War powers agreed for the first time to limit their nuclear arsenals in the SALT Treaty (Strategic Arms Limitation Treaty Agreement), and the Cold War reached a relatively stable configuration of proxy wars and jockeying for influence.
With the collapse of the Soviet Union in 1991, these Cold War constraints were lifted, and former Soviet colonies broke free. Now the full bloom of malignant conflicts has been free to flower globally, and dozens of hot conflicts are underway on every continent.
Against this sobering intersection of financial contraction, geopolitical instability and resource depletion stands a belief in the transformative power of technology. History seems to support the optimistic notion that energy densities and per capita consumption can keep rising basically forever, as humanity has moved from human power to harnessing animal power and then sail and water power, and moved from burning wood to coal to oil in a movement up to ever-denser energy densities.
For an example of this sort of thinking, let's turn to a recent interview with Silicon Valley venture capitalist Vinod Khosla, who is justifiably renowned for his foresight and investing acumen. In this interview, he predicts $1/gallon biofuels will make oil and gasoline uncompetitive; who bother with oil when biofuel is so much cheaper?
ON THE RECORD: VINOD KHOSLA (S.F. Chronicle)
I have no question that in 10 years, there's no way oil will be able to compete with biofuels. Even in five years. Now it will take a long time to scale biofuels, but I'm the only one in the world forecasting oil dropping in price to $35 a barrel by 2030. I'll put it on the record: Oil will not be able to compete with cellulosic biofuels.According to Department of Energy Quick Oil Facts, the US consumes about 390 million gallons of gasoline per day. At 28 gallons of gasoline/barrel of crude that amounts to 13 million barrels of crude oil equivalent-- about 65% of the crude oil consumed by the USA (21 million barrels a day).
So even if wind, solar, geothermal, nuclear, tidal, etc. was generating all the nation's electrical power, our current lifestyle would require about 450 million gallons of gasoline or equivalent per day.
(Recall that biofuels only provide at best 85% of the energy density of gasoline, hence you need 115 gallons of biofuel to generate the same energy in 100 gallons of gasoline/petrol.)
Is it plausible that giant algae farms, switch grass, wood chips, lawn clippings, etc. can possibly generate 450 million gallons of liquid fuel a day?
And what if these enormous new industries actually require more energy than the current petroleum complex to operate? Then perhaps we'll need 500 million gallons of gasoline equivalent liquid fuels because the harvesting, cooking, distilling, refining and transporting of biofuels requires more energy than pumping, cracking and transporting petroleum products.
Away from the glow of wishful thinking, it seems there are a couple of serious
problems with biofuels:
Let's start with an article from Scientific American: Biofuels Are Bad for Feeding People and Combating Climate Change By displacing agriculture for food—and causing more land clearing—biofuels are bad for hungry people and the environment
The studies do find some benefit from biofuels but only when planted on agricultural land too dry or degraded for food production or significant tree or plant growth and only when derived from native plants, such as a mix of prairie grasses in the U.S. Midwest. Or such fuels can be made from waste: corn stalks, leftover wood from timber production or even city garbage.Here is the academic paper which blew the doors right off the fantasy that biofuels could replace fossil fuels in some sort of seamless transition that left all 220 million vehicles in the U.S. purring along on billions of gallons of biofuels.
I strongly recommend reading the entire 12 page paper, which is written in clear English and is supported by tables and well-sourced data. Ethanol Production Using Corn, Switchgrass, and Wood; Biodiesel Production Using Soybean and Sunflower.
Here is the summary:
Energy outputs from ethanol produced using corn, switchgrass, and wood biomass were each less than the respective fossil energy inputs. The same was true for producing biodiesel using soybeans and sunflower, however, the energy cost for producing soybean biodiesel was only slightly negative compared with ethanol production.Consider the consequences of these points from the report:
About 50% of the cost of producing ethanol (42c/ per l) in a large-production plant is for the corn feedstock itself (28c//l) (Table 2). The next largest input is for steam (Table 2).Now perhaps it could be argued that if the U.S. scaled up alternative sources for electricity to some nearly unimaginable height, then the excess power could be converted to steam to cook and process 500 million gallons of liquid fuel a day.
But exactly what are the cost and resource inputs for this stupendous amount of energy? Thermonuclear power? Nice, but that is science fiction at the moment, not science.
Given the evidence before us, it seems completely improbable that the U.S. can produce billions of gallons of biofuels without burning stupendous quantities of imported petroleum to do so.
The cycles and the end-games are intersecting, and technological fantasies are not actually addressing the problems at hand. Energy densities will have to drop significantly, and net energy production must rise significantly (energy produced minus fossil fuels required to harvest, mine, process and transport the alternative fuel). There is precious little evidence that biofuels can be produced in such massive quantities without using equivalently massive quantities of fossil fuels.
