will be gone before economists know it |

"My father rode a camel.
I drive a car. My son rides in a jet airplane. His son will
ride a camel."
— Saudi saying
Just as the Native tribes of the Midwest called themselves
"The People of the Buffalo," Americans - and residents of
other industrialized nations - can be described as being
members of the "Hydrocarbon Tribe." Cheap fossil fuels,
particularly crude oil, power our factories and encourage
auto-dependent sprawl. Rapidly expanding economic
globalization has made the U.S. increasingly dependent upon
oil-fueled, long-distance transportation. Petrochemicals are
also the source materials of a great many products including
plastics, pesticides, fertilizers, medicines, computers,
asphalt, glues, paints, solvents, inks and detergents.
Economists and politicians assure us that the flow of cheap
oil will continue for decades to come. The Bush
administration assures us that our oil-dependent way of life
will be protected at all costs.
However, a growing number of petroleum geologists are
issuing warnings in prestigious scientific journals like
Science, Nature and Scientific American that the 100-year
oil era is quickly coming to a close. They also say that
"the market" will not warn us of the impending oil shortage
in time to fully prepare for it.
A 2001 book by Princeton Professor Emeritus of Geology,
Kenneth Deffeyes explains why we need to start planning for
the post-oil era now. Titled Hubbert's Peak: The Impending
World Oil Shortage (www.HubbertPeak.com), his book is a
short course in petroleum geology. Deffeyes' aim is to
explain how the predictions of declining oil production are
made.
In new oil fields, production increases rapidly. After the
cheaper, easier to recover oil has been pumped, recovery
expenses go up. Production slows down, peaks, and then
begins to decline.
Shell Oil petroleum geologist M. King Hubbert realized
decades ago that production peaks when roughly half of the
ultimately recoverable oil has been removed. In 1956,
Hubbert plotted a bell curve that showed U.S. oil production
would peak around 1970. He recalculated in 1962, using
updated production statistics from U.S. oil wells and new
oil reserve discovery data, and ended up with the same
results. Hubbert also discovered that the production curve
followed the discovery curve by about 11 years.
Petrogeologists debated Hubbert's predictions until 1970,
when production in fact did peak. The U.S. has since made up
the ever-increasing disparity between supply and demand with
a growing dependence on Middle Eastern oil.
In the 1990s, geologists began to calculate a global curve
for oil, using Hubbert's methods.
Just as the domestic oil production curve follows the
domestic oil discovery curve, global production trails
global discoveries. Global discoveries peaked in 1962 and
have been declining ever since. Presently, four barrels of
oil are consumed for every new barrel found.
Approximately 850 billion barrels of oil (Gbo) were
extracted by 1996. Petroleum geologists Colin Campbell and
Jean Laherrére calculated at that time that there was 1
trillion Gbo of ultimately recoverable oil remaining, for a
total of 1.8 trillion Gbo (See their March 1998 Scientific
American article, "The end of cheap oil" at www.dieoff.org/page140.htm).
Other geologists estimate that the total of ultimately
recoverable oil may be as much as 2.1 Gbo.
Campbell and Laherrére's Hubbert curve indicates that global
oil production will peak by 2008, barring an extended global
recession. Deffeyes says that, based on a number of
geologists' estimations, the global oil peak will occur
sometime between 2003 and 2009.
One USGS geologist has dubbed the impending peak the "Big
Rollover."
Many people erroneously believe that the "second half" of
the oil supply can be recovered as easily, and cheaply, as
the first half. Most economists assume the rise in oil
prices will be gradual, allowing plenty of time for
increased investments in oil recovery technology and oil
alternatives. But, the price of oil has no relation to how
near we are to the peak in production. Price is determined
only by the relation between supply - the flow of oil from
today's wells - and demand.
Oil demand has been growing exponentially for over 100 years
and is expanding more than 2 percent annually. Production
would have to increase five times for everyone on Earth to
consume oil at the current U.S. per capita rate.
Campbell and Laherrére wrote, "It is important to realize
that spending more money on oil exploration will not change
this situation. After the price of crude hit all-time highs
in the early 1980s, explorers developed new technology for
finding and recovering oil, and they scoured the world for
new fields. They found few: the discovery rate continued its
decline uninterrupted. There is only so much crude oil in
the world, and the industry has found about 90 percent of
it."
If we wait until oil production peaks there may not be
enough time to make a smooth transition to renewable energy.
Today's global energy system required major investments in
time, money and energy to install the wells, mines,
pipelines, roads, tankers, refineries, power plants, engines
and factories needed to burn oil and other fossil fuels. The
transition to renewable energy sources will require another
massive investment in infrastructure. Deffeyes warns that
after the oil peak, oil prices will jump, making such
investments costly. A rise in the price of oil will also
lead to increased costs for everything dependent upon oil
for manufacturing or transportation. For example, each
calorie of food grown by modern agricultural methods
requires 4-10 calories of fossil fuel. Oil is part of the
food production process at almost every step, beginning with
the production of synthetic pesticides and continuing to
powering your freezer.
Economists say that as the price of oil rises, it will
become profitable to recover poorer deposits of oil, and to
produce oil from oil shale and tar sands. This is true only
from a monetary point of view.
Since it takes energy to get energy, as the
easier-to-recover oil and other fossil fuels have been
removed, the energy needed to recover remaining supplies has
steadily increased. And an energy "source" that requires
more energy to produce than it provides is really an
unprofitable "energy sink."
Stuart Rodman, the director of communications for the
Ecological Life Systems Institute, says in the Spring 2001
issue of Auto-Free Times (now called Culture
Change) "Net-energy analysis first reached
public attention in 1974. At that time, Business Week
reported that oil scientist Howard Odum had developed a 'New
Math for Figuring Energy Costs.' To the surprise of many,
Odum's new math indicated that stripper oil well operations
were energy sinks. ... These operations could only be
profitable when 'subsidized' by cheap, regulated oil, which
was used to produce deregulated oil."
Jay Hanson writes about oil analyst Richard Duncan's work on
U.S. oil fields in the March 8, 2001 article, "Synopsis" at
www.dieoff.com: "In the 1950s, oil producers discovered
about 50 barrels of oil for every barrel invested in
drilling and pumping. Today, the figure is only about 5 for
1. Sometime around 2005, that figure will become 1 for 1.
Under that latter scenario, even if the price of oil reaches
$500 a barrel, it wouldn't make 'energy sense' to look for
new oil in the USA."
Energy suppliers are investing in natural gas power plants
and gas-fueled motor vehicles. Hanson points out, "North
American natural gas has no excess capacity. It disappeared
several years ago. What we do have is extremely aggressive
decline rates in almost every key production basin, making
it harder each season to keep current production flat. ...
Forecasts show gas demand could outstrip supplies from
traditional sources by as much as 4 billion cubic feet a day
within a decade!"
Meanwhile, the global natural gas production peak may come
as soon as 2020.
To complicate matters even more, one-third to one-half of
the natural gas produced in the lower-48 states is
contaminated with nitrogen, carbon dioxide and hydrogen
sulfide. These compounds must be removed or the gas must be
blended with less contaminated gas. Such processing reduces
the net energy value of natural gas.
The construction of a gas pipeline to Alaska and Canada,
where there are large untapped deposits of gas, could
temporarily mitigate a North American gas shortage, says
Hanson.
For gas to be shipped across oceans, it must be liquefied.
There is a shortage of liquefied natural gas facilities,
shipping tankers and specially equipped ports. In addition,
the liquefication process causes a 15 to 30 percent net
energy loss.
Natural gas pipelines, filling stations, motor vehicles,
airplanes and other infrastructure would also have to be
built to support the widespread use of natural gas.
At the current rate of depletion, coal production would not
peak until the 22nd or 23rd centuries. However, coal is
bulkier and heavier than the energy-equivalent volume of
oil. It also burns at a lower temperature than oil and
cannot be used in internal combustion engines.
In addition, coal deposit quality is declining. Contaminants
like sulfur and arsenic must be removed, leaving ever less
net energy available. Furthermore, the average heat content
of coal is dropping. From an energy-profit ratio of 177:1 in
1954 to 98:1 in 1977 it is projected to drop to 0.5:1 by
2040.
Coal is also the dirtiest fossil fuel, causing acid rain,
particulate pollution, smog and climate change. Mining
methods like "mountaintop removal" are as environmentally
destructive and energy-intensive as they sound.
The U.S. does have a huge oil shale deposit stretching
across parts of Wyoming, Utah and Colorado. The Green River
Formation contains as much oil as all the world's
conventional oil reserves.
But oil shale deposits are "unborn" oil fields. Oil fields
form when geo-thermal heat "cracks" the organic material in
oil shale, causing oil to ooze out and collect in reservoir
rocks over millions of years. Therefore, oil shale must be
crushed and heated to high temperatures to recover the oil,
greatly reducing its net energy value.
Tar sands are "dead" oilfields that have eroded away,
leaving behind highly viscous oil or tar (bitumen). Tar
sands provide less than half the net energy as the same
volume of oil and deposits are heavily contaminated with
sulfur.
The harder-to-reach oil shale and tar sand deposits are
energy sinks.
Moreover, mining operations for oil shale and tar sands
produce prodigious amounts of rock slag and oily wastewater
that is dumped into huge holding ponds. Neither oil source
is economically profitable when all expenses are considered.
There is a 100-year supply of uranium. To create more
fissionable material, spent fuel rods would have to be
reprocessed in breeder reactors to concentrate the remaining
uranium and plutonium for reuse.
Hanson says, "A significant expansion of nuclear power -
even the five-fold expansion widely canvassed before the
incidents at Three Mile Island and ... Chernobyl - would
out-run readily accessible supplies. These supplies include
both deposits previously exploited but moth-balled due to
lack of current demand, and known high concentration pockets
that could be opened up quite quickly. Therefore, the
expansion of nuclear (energy) would highlight the need to
bring rapidly back on course the development of fast-breeder
reactors."
Writer Ted Trainer wrote in "The Death of the Oil Economy,"
in the Spring 1997 Earth Island Journal, "Relying on nuclear
energy to provide (a projected world population of) 11
billion people with First World living standards would
require a system of 250,000 giant breeder reactors using
around 1 million tons of plutonium" per year.
Uranium has a radioactive half-life of 10,000 years.
Plutonium is the most toxic substance on Earth. It has a
half-life of 240,000 years, is dangerous for several
half-lives, and is the main ingredient in nuclear warheads.
Expecting waste depositories and abandoned reactor sites to
be geologically stable for tens and hundreds of thousands of
years is a gamble. There is also the dangerous prospect of
transporting nuclear materials around the world. In
addition, no human civilization has lasted longer than 1,000
years without a military invasion.
Furthermore, with the energy needed to mine and process
uranium, build, maintain and decommission nuclear power
plants, and steward long-term storage of nuclear waste,
nuclear energy is an energy sink. It is also financially
unprofitable for nuclear energy companies, unless many of
the risks and expenses are "externalized" onto taxpayers,
the human population, and the environment, with subsidies
and exemptions from safety precautions.
Scholar Richard Heinberg, who is researching
petroleum-related scientific, historical, social and
political issues for his book The Party's
Over, writes in
his Oct. 2001 MuseLetter, "Competition
for the world's remaining oil will determine the political
and economic outlines of the coming century. The Caspian Sea
region, as one of the last untapped oil and natural gas
reservoirs, will be of extreme strategic significance. For
the past few years, nations and oil companies have been
vying for pipeline access routes to that reservoir. The
route favored by the U.S. - and by Unocal and Halliburton
(the drilling services company of which Dick Cheney was
formerly CEO) - happens to run through Afghanistan. The
company that will likely be tapped to build the pipeline is
a Saudi Arabian construction firm owned by the bin Laden
family."
Also in the region, Azerbaijan, Kazakhstan, Turkmenistan and
Uzbekistan contain around 15 billion barrels of oil and 9
trillion cubic meters of natural gas. U.S. strategies to
take control of the region have been around since before the
Carter Administration.
In 1997, Unocal led an international consortium seeking to
build a natural-gas pipeline from Turkmenistan to Pakistan
via Afghanistan. The Clinton administration and the
Pakistani Inter Services Agency facilitated negotiations
with the Taliban. However, the civil war in Afghanistan
forced Unocal to pull out.
In 1998, Unocal testified before the Congressional House Subcommittee on
Asia and the Pacific that an oil pipeline through
Afghanistan was necessary to transport Caspian oil to the
Indian Ocean.
In May 2001, U.S. State Department, Iranian, German and
Italian officials met in Geneva, Switzerland to discuss
removing the Taliban and installing a "broad-based
government" in its place. The topic was discussed again at
the Group of Eight summit in Genoa, Italy in July 2001. The
BBC reported Sept. 18 that senior American officials told
former Pakistani Foreign Secretary Niaz Naik in July that
the U.S. would pursue military action against Afghanistan by
mid-October 2001.
From February to August 2001, the Bush administration
negotiated directly with the Taliban over a pipeline route.
In August the negotiations broke down after the U.S.
threatened military action.
Michael T. Klare reported in the Nov. 5, 2001 issue of The
Nation that Osama bin Laden's "ultimate objectives" in a war
with the U.S., in addition to control of the Caspian Basin,
"include the imposition of a new Saudi government, which in
turn would control the single most valuable geopolitical
prize on the face of the earth: Saudi Arabia's vast oil
deposits, representing one-fourth of the world's known
petroleum reserves."
The only region with unknown and possibly significant oil
and gas reserves is the South China Sea. Nations ringing the
Sea are currently arguing over who owns what part of the
ocean bottom.
However much political leaders may hope that Saudi, Caspian
and South China Sea oil and gas will power industrial
civilization for decades to come, Deffeyes says that "No
initiative put in place starting today can have a
substantial effect on the peak (oil) production year. No
Caspian Sea exploration, no drilling in the South China Sea,
no SUV replacements, no renewable energy projects, can be
brought on at a sufficient rate to avoid a bidding war for
the remaining oil."
Economist James K. Galbraith says in a book review of
Hubbert's Peak that "If we (had to) pay a rising dollar
price (for oil), it could mean an essentially endless
depression" in the U.S.
He goes on to say, "But there is another possibility. We
could control the dollar price, so that the oil shortfall
remains largely invisible to the American consumer. One has
to believe that this idea has occurred to the oilmen in
charge. The problem then is that conditions elsewhere have
to be much worse. For this strategy implies pricing
developing countries out of the oil market by driving their
currencies down. This can be done by driving a hard bargain
on their debts. Eventually, irrigation pumps will run dry,
and the Green Revolution will start running backwards. From
the standpoint of the developing world, the game is
zero-sum; our success in a war for control is their descent
into famine."
One only has to look at the current situation in Argentina
to see what debt-pressure leading to a devaluation of a
nation's currency does to increase human suffering and
social unrest.
The International Monetary Fund and the World Bank,
controlled by the economically elite G-8 nations, have been
"driving a hard bargain" on developing countries' debts
since the early '80s.
Story Update July
2003:
The best book on the peak of global oil production for the
layperson is The
Party's Over, by Richard Heinberg.
Colin Campbell and his organization the Association for the Study of Peak Oil
& Gas held the first International Workshop on Oil Depletion
in May 2002 and the second conference in May 2003. The conference Web site is
www.peakoil.net.
Oil
& Gas Journal
reports that global oil production peaked in 2000.
Production levels in 2001, 2002 and so far in 2003 were
below that of 2000. If the bell-shaped world oil production
curve is mathematically smoothed out a little, the actual
peak year will be 2004.
On March 6,
2003, the Dow-Jones news service reported that Saudi Arabia
had notified Western oil companies that collectively, Saudi
oil fields have reached maximum production. This means that
Saudi Arabia, which possesses the largest volume of
unrecovered oil in the world, is passing its own peak of
production.

The race to renewables (SIDEBAR)
A transition to renewable energy sources is inevitable.
However, renewables cannot fully substitute for the
concentrated energy of fossil fuels. Renewable sources
provide a limited flow of energy at a time. When renewable
energy systems installers work with homeowners and
businesses to properly "size" a system, they recommend that
the buyer "power down" his or her use of energy.
Permaculture co-founder David Holmgren says, "The most
productive sustainable systems imaginable may be able to
provide for the needs of 5 or even 10 billion people.
However, they would never sustain large-scale cities, a
global economy, and Western material affluence."
Here is a a partial list of steps we need to take:
Our first task is to maximize efficiency - the "soft energy
path" of Amory Lovins. Additionally, we must consume less,
share more, reuse and recycle everything, and stop the
growth of the human population and the physical size of the
economy.
"Biomimicry," design mimicking the ecological principles of
nature, has great potential: "Industrial ecology" improves
the operating efficiencies of factories and industrial
parks. Permaculture maximizes the agriculture efficiency and
productivity of the landscape.
Green tax reform would switch local and national taxes away
from payroll, income and sales taxes, and onto fossil fuel
use, thereby encouraging alternative energy use.
Clustered, mixed-use pedestrian-centered communities
designed for efficient bicycling and mass transit will
replace sprawl.
Globalized trade as we know it will end. Transporting
"cheap" food and goods long distances makes no energy sense.
Currently, solar electric photovoltaic cells require twice
as much energy to manufacture as they provide. Further
research will reduce PV embodied energy to the point that PV
systems provide net energy. Mass-producing PV systems would
make PV cost competitive with fossil fuels. Even at
the present level of PV efficiency, using some of our
remaining oil to produce PV systems that will last decades
after the oil peak would be useful.
Passive solar architecture and thermal heating technologies
(such as hot water heaters) are already cost and energy
efficient.
Wind energy is also cost competitive with fossil fuels.
About 13 percent of the U.S. has sufficient wind speeds. The
Great Plains and coastal regions could supply 20 percent of
U.S. electricity using current technology. Wind-powered
sailing ships could be revived for sustainable international
trading.
Hydroelectric power supplies 2.3 percent of global energy
needs. The destructive environmental effects of large dams
are increasingly recognized. Microhydropower for homes and
businesses is feasible in some areas.
Geothermal energy is also feasible. However, geothermal
energy is only practical in certain regions. And the
life-expectancy of some geothermal fields may be short. (See
related story, "Creating Green Electricity from Sewage,"
January FTP.)
Biodiesel is a biodegradable fuel made from vegetable oils.
John B. Campbell of Ag Processing, Inc. says that current
soybean production, the most likely candidate for
large-scale biodiesel production, could produce only 130
million gallons of biodiesel per year. However, the U.S.
uses 40 billion gallons of diesel per year. Further
expanding oilseed production would require planting land now
left fallow as part of federal conservation programs and
transferring land from export grain production to biodiesel
production. These steps might replace 10 percent of
conventional diesel with biodiesel. However, if less land is
devoted to producing grain for export, the decreased grain
supply would lead to higher grain prices, exacerbating world
hunger.
Hydrogen will likely be a key part of the post-fossil fuel
world, especially hydrogen fuel cells. Liquid hydrogen can
power vehicles and factories. Currently, most hydrogen is
manufactured from natural gas at a net energy loss. The
future is in solar hydrogen systems that create hydrogen
from water.
