Since the beginning of our short oil era around 1860,

world population has increased dramatically. This population

growth has been fueled substantially by oil. In the United

States, food travels more than 1,000 miles on average, requiring

over 10 times the petroleum energy to produce than its

solar energy food value (calories). As a practical matter, we

are eating mostly petroleum.


Many societies throughout history have faced resource

depletion. History tells us that Plato deplored the deforestation

in Greece, and that the Greeks started using passive

solar orientation in their settlements when they ran out of

firewood. Archeologists have found many societies that disintegrated

because they depleted their resources with no

concern for the future. Some simply abandoned their settlements

and moved to fertile land. Others, like the people on

Easter Island, could no longer move. They had cut down all

their trees and couldn’t even make crude boats to fish.

Developed and developing countries alike are addicted to

cheap oil. For the United States, depletion is going to be especially

difficult. Americans use oil as if it will never run out.

The country is designed and built around cars using cheap

gasoline. With fossil fuel resources becoming scarce, we

have to learn to make do with what we have peacefully or

we will have war, depleting humanity’s collective resources

even further.

What might be the possible early reactions to peak oil?

Conservation: Whenever natural disasters or political

disruptions shed light on our energy

vulnerability, earnest appeals for

conservation can be heard. Conservation

can be voluntary: I can

choose to buy a Toyota Prius and

still go to the beach on the weekend.

I will use less oil, but my

lifestyle will be preserved.

 

Deprivation: As oil supplies

continue to dwindle, energy conservation

will cease to be voluntary.

That may lead to rationing if we

make a reasoned response. But if

depletion is not managed effectively,

 

deprivation will overwhelm

efforts to conserve rationally. As

shortages impact the industrialized

world, trips to the beach will be

sparse. Lifestyles will change.

 

Conflict:With oil as an essential

foundation of productive modern

agriculture and starvation already

intense in certain regions, it can be

argued that the poor of the world are

already deprived, involuntary participants

in energy conservation.

Energy inequities will continue to

grow between the haves and the

have-nots, and the struggle over the

remaining oil reserves will intensify.

 

A Wake-Up Call

Peak oil is an emerging reality. To avoid disaster, solar energy must rise to meet the oil depletion challenge.

Some say the conflict in Iraq is a grab for oil. Whether true or not,

how might we avoid conflicts over energy resources?

Substitution: We will inevitably have to find other energy

sources, substituting new energy for oil and what oil does. Are

there solutions close at hand?

 

No Answers in Non-Conventional Oil, Nuclear

One place where the peak oil message is being heard is at the

margins of the oil, gas and coal industries. As energy prices rise

exponentially, researchers are attempting to exploit carbon-intensive,

non-conventional fossil fuels to replace transportation fuels.

Massive investments have been made to extract tar sands in

Alberta; research is ramping up to find a way to convert oil shale

in Wyoming and Colorado; and improved technologies are being

developed to convert coal to liquids, using the same process that

fueled Hitler’s desperate army.

But such attempts have produced inadequate amounts of net

energy. For heat to extract oil from tar sands, natural gas equivalent

to one-third of a barrel is used per barrel. This natural gas

is in addition to the liquid fuels and electricity needed for mining,

refining and environmental remediation. Recognizing rising

natural gas prices, advocates are even suggesting nuclear power

to replace natural gas for heat in the extraction process.

Nuclear power is also being examined for the extraction of oil

shale. This misnamed substance (neither shale nor oil but marlstone

and kerogen, an immature hydrocarbon) must be heated

under pressure to convert it to oil. One proponent in Colorado

Fossil Fuel Gap?

Solar energy far exceeds all other possible forms

of substitution, with none of nuclear energy’s safety

and waste-disposal challenges.

envisions a nuclear facility generating more power to heat oil shale

in situ than all electricity now consumed statewide. Water requirements

and environmental impacts could be huge.

As the informed public becomes aware of the impact of greenhouse

gases, nuclear power is being promoted again, this time as

a carbon-free energy source. But the popular notion that nuclear

is carbon-neutral is faulty. High-grade uranium ores have already

been exploited, and the mining and refining of lower-grade uranium

ores are increasingly fossil-fuel intensive.

If all bets are placed on marginal fossil fuels and nuclear

power, the consequences for society will be dire. Perpetuating the

automotive fleet, for example, may seem laudable. But propping

up the fleet with low-grade fuels could be more dangerous than

doing nothing because, as U.S. Rep. Roscoe G. Bartlett suggests in

his article (page 27), these marginal sources too will run out, and

humanity will be left high and dry.

 

Only Solar Energy Can Fill the Gap

Meanwhile, renewable energy technologies are being brushed

aside by some peak oil “experts” as too intermittent or diffuse to

merit serious attention. Let’s examine a few of these objections

to a full-scale transformation to renewables.

“Solar energy, plant biomass and other renewable forms of energy

are diffuse forms of energy.”

Direct sunlight is indeed diffuse, but thin collectors are a

perfect match to diffuse. Mirrored surfaces on solar concentrators

are thin. Solar cells are thin, and thin-film cells are even thinner.

Furthermore, sunlight is far more evenly distributed around the

globe than is oil.

“Photovoltaic electricity is expensive.”

The profitability test is often the result of accumulated political

decisions favoring special interests. In economics it is formally

assumed that oil and other natural resources have no value until

they are “produced” (i.e., extracted), and then the only value

assigned to the resources is the cost of extracting them. They are

free for the taking, and so we have been paying nothing for the

inherent value of oil. Lobbying efforts have provided large subsidies

for oil. Externalities are not charged at the gas pump. Preferential

tax treatments, highway construction and defense budgets

underpin the oil economy.

Renewable energy subsidies are beginning to level the playing

field. As fossil fuel costs increase, the economics of renewable energy

will transform the market. (See January/February SOLAR TODAY

 

for features on the theme, “Solar Energy Cost Breakthrough Ahead?”)

“The EROI (energy return on investment, or net yield) for fossil fuels

tends to be large, while that for solar tends to be low.”

A hundred years ago, oil gushers yielded high net-energy recovery

rates, but today solar, hydroelectric and wind power have net

energy yields higher than conventional fuels such as oil, gas and

coal, and an order of magnitude better than non-conventional fossil

fuels. With their inherently high net-energy yields, renewables

can be ramped up rapidly. (See table, “Estimated Net Energy Yield of

Conventional and Renewable Sources in the U.S.,” page 16.)

“Neither solar nor wind power is an immediate, large-scale solution

to the energy problem. … Plants, on average, capture only about 0.1

percent of the solar energy reaching the Earth.”

 

Humanity’s “primary energy production,” including all fossil

fuels, nuclear power, hydroelectric and renewables, is 13 terawatts

(equivalent to 13,000 large power plants), less than 1/100 of 1 percent

of the 170,000 terawatts continuously delivered to the earth

as sunlight. With 600 terawatts of terrestrial potential, solar energy

far exceeds all other possible forms of substitution. (See sidebar,

“How Will We Fill the Fossil Fuel Gap?” page 17.)

 

Transportation in a post-cheap-oil world poses special challenges.

If non-conventional fossil fuels are untenable and

A Solar Future Long Anticipated

When Hubbert predicted global peak oil, Farrington Daniels

focused on the solution.

The afternoon of Sept. 15, 1948, was an important date for

solar energy, the petroleum industry and the International

Solar Energy Society (ISES). The American Association for the

Advancement of Science (AAAS) was 100 years old, and AAAS

President Edmund Sinnott, Ph.D., invited three prominent

speakers for a Symposium on Sources of Energy at the Centennial

Celebration in Washington, D.C.:

 

Dr. M. King Hubbert, a geologist working for Shell Oil,

addressed oil depletion, as the “Golden Century of Oil” was

getting under way.

 

 

Dr. Farrington Daniels, a physical chemist who had been in

charge of the Chicago branch of the Manhattan Project and

later started the organization that would become ISES,

addressed the future of solar energy, while solar energy was still

a dream.

 

 

Dr. Eugene P. Wigner of Princeton, who would receive

the 1963 Nobel Prize in Physics and who had worked on the

Manhattan Project for Daniels, addressed the future of atomic

energy, about eight years before there were any commercial

power reactors.

At this symposium, Hubbert presented his first paper on

what would become known as the “Hubbert Curve,” the brief

period in human history during which petroleum was discovered;

adopted by society as its principal energy source; extracted

in ever greater quantities; burned with no serious concern for

the future; fostered affluence, wars and pollution; became ever

harder to find and “produce”; and was destined to decline

inexorably — leaving us no choice but to switch to sustainable

energy sources.

Even in this first paper, Hubbert warned that the post-oil

transition process would be extremely difficult. Neither Daniels

nor Wigner had much to offer except hope; solar and atomic

energy technologies were still primitive. Despite Daniels’ experience

in the Manhattan Project (or perhaps because of it), he

decided to concentrate on solar energy, forming the society now

known as ISES and creating a solar energy program at the University

of Wisconsin-Madison that remains famous.

Getting to know Hubbert made Daniels aware of oil depletion

and the energy deficiencies that solar energy would have to

address. In 1964 Daniels wrote that U.S. oil “production” would

peak about five years later, as Hubbert had predicted accurately in

1956, and that worldwide oil scarcity would begin shortly after

2010. As humanity now encounters the Hubbert Peak, the man

who established ISES to meet the challenge of oil depletion will

inspire members of the solar community in the decades ahead.

A Wake-Up Call

Humanity’s “primary energy

production,” including all fossil

fuels, nuclear power, hydroelectric

and renewables, is 13 terawatts.

Solar energy has 600 terawatts

of terrestrial potential.

March/April 2006 19

transportation is powered almost exclusively by liquid fuels,

it is tempting to propose biomass as a substitute for oil. In the

United States, 1 billion tons of biomass are managed each

year. To meet all our energy needs, 7 billion tons more would

be required. Obviously, electric airplanes or cargo ships are

impractical, so biomass will play an important role in our

energy future. But liquid fuels exclusively from plant material

will be possible for transport at only about one-tenth the

present level worldwide. Something has to give.

Considering society’s huge investment in the vehicle fleet

and these limitations of biofuels, it is difficult to imagine the transformation

of transportation to renewable energy sources. To

make the shift, the premise that solar energy must be converted

into fuel has to be challenged. A direct path from sunlight to

electricity can be 10 times as efficient as photosynthesis. Solar

energy can’t be touched or put into a bottle. Solar is radiant

energy, not a solid, liquid or gas.

Electricity from renewables is ideally suited for urban transportation.

It is nonpolluting and well-suited for fixed guide rail

and automated routing of traffic, and an electric vehicle is at

least twice as efficient as a gasoline vehicle. We are ready for

a good reason to get rid of the internal combustion engine in

dense urban areas, where it is about as practical as a campfire

in the kitchen. Efficiency in the face of oil depletion is that

compelling reason.

Solar technologies continue to improve, and so do electric

vehicles. A battery with three times the energy density of

lead-acid and a charging time under two minutes is scheduled

for introduction in 2007 or 2008. Shanghai has an electromagnetic

propulsion maglev train that travels at 270 miles per hour.

 

 

Getting Up to Speed: Think Terawatts

According to Campbell and other leading peak oil experts, permanent

oil decline will begin during this decade and will likely

proceed initially at 2 to 8 percent per year. If oil declines at 4 percent

and photovoltaic manufacturing grows at 40 percent per year

until 2020, PV would meet less than 20 percent of the oil shortfall

without meeting any demand growth. If the PV industry sustains

growth averaging 50 percent or more per year, it will contribute

significantly. Though such growth is an aggressive goal, it

is realistic under a scenario slightly more ambitious than the

two-year doubling time projection that Ron Larson presents in this

issue’s “Chair’s Corner” (page 4). As nonsilicon-based solar products

quickly become commercialized, this goal is even more feasible.

(See graphic, “As Oil Supplies Decline, Photovoltaic Capacity

Grows,” left.) Developing similar growth rates for all renewables,

it will be possible for sustainable solutions to realize their potential

for oil, gas and coal substitution. The sidebar, “Making the

Transition,” (page 29), samples some industry proposals.

France converted from zero to nearly 100 percent nuclear

power in less than 20 years. Renewable energy technologies have

higher net-energy yield than nuclear by far and are faster to

install, so it will be possible to ramp up in even less time. If

others continue to insist that nuclear power, tar sands or coal-toliquids

are options, the move to renewables will be even more

critical as the only pathway that avoids potential nuclear terrorism

and curbs global warming.

We must recognize the limits of our fossil fuel reserves and

begin to push for rapid growth in solar energy. For the first time

in history, all of humanity will share the same problem. This common

challenge can help unify us, to recognize the futility of war

and to make governments more responsive to our needs. We will

need large national and international programs, similar in ambition

and spirit to the Apollo “Man on the Moon” program, to

reduce our oil consumption and to create alternative energy

sources. This transition will provide many good local jobs that

cannot possibly be outsourced, and we will need a significant

grassroots effort.

If we get it right, we will be able to share a future of clean air

and fresh water, viable oceans, thriving forests and peaceful coexistence.

We must get it right, and be proud that we are members

of the generation entrusted with the task.

Soaring oil prices have raised concern about the relative

supply and demand of the world’s premier

fuels, having a central place in the modern economy.

It has led people to ask, “Are we running out of

oil?” A sensible short response would be, “Yes, we

started doing that when we produced the first barrel.” The

world is not about to run out of oil, but what it does face is the end

of the First Half of the Age of Oil. That opened 150 years ago when

wells were drilled for oil on the shores of the Caspian and in

Pennsylvania. The cheap, convenient and abundant energy it

supplied, led to the growth of industry, transport, trade and agriculture.

This growth was accompanied by the creation of huge

amounts of financial capital, as banks lent more than they had on

deposit, confident that tomorrow’s economic expansion was adequate

collateral for today’s debt. Many people came to think that

it was money that made the world go round, when in reality it was

an abundant supply of cheap energy, much derived from oil.

Petroleum geology has made great advances in recent years,

such that the conditions under which oil and gas were formed in

nature are now well understood. In fact, it transpires that the bulk

of the world’s current production comes from deposits formed in two

brief epochs of extreme global warming 90 million and 150 million

years ago. Algae proliferated in the warm sunlit waters, providing

the raw material that eventually became oil. It was preserved and

trapped in places having the right combination of geological conditions.

A glance at the oil map shows that oilfields are clustered in

such exceptional places, which are separated by vast barren tracts.

Natural gas was formed in a similar way, save that it was derived

from vegetal remains as found in the deltas of tropical rivers. Ordinary

oil also broke down into gas if overheated by excessive burial.

Oil and natural gas are clearly finite resources, formed in the

geological past, which in turn means that they are subject to depletion.

That is not a difficult process to understand, as every beerdrinker

knows. The glass starts full and ends empty; the quicker

he drinks it, the sooner it is gone; and every bar has a closing time.

So, how far along the oil and gas depletion curves are we? The first

step in answering this question is to ask how much has been found

so far and when it was found, because production has to mirror

discovery after a time-lapse.

They sound like simple questions, being just a matter of looking

up the data, but as we dig into the details, we find a minefield

of confusion, obfuscation and disinformation.

liked to mention, fearing that it smacked of a dwindling asset that

did not sit well with the stock market, but

now some of them do begin to be more

forthright. An example is Chevron, whose

CEO deserves great credit for his frank presentation

(see www.willyou

joinus.com). The official institutions, for

their part, tend to continue to publish

bland scenarios and half-truths, recognizing

that their governments are not yet

ready to face bald reality.

In most contexts, the term reserves

 

means something sure, but that is not the

case for oil. Estimating the size of an oilfield

early in its life poses no particular scientific

or technical problem. The difficulty lies

in the reporting. Oil in the ground is a

financial asset to its owners, against which

money can be borrowed. Accordingly, the

Securities and Exchange Commission

(SEC), very properly moved in the early days of U.S. oil production

to introduce strict reporting rules. The SEC recognized two

main classes: proved producing reserves for the expected future production

of current wells; and proved undeveloped reserves for the

expected production of yet-to-be-drilled infill wells.

The rules were designed to prevent fraudulent exaggeration,

but smiled on underreporting as laudable prudence. In practice,

the major international oil companies reported just as much as

they needed to report in order to deliver satisfactory financial

results, building up for themselves a useful stock of unreported

reserves to tide them over lean discovery years and cover any temporary

setback around the world. As a result, they were able to progressively

revise their reported reserves upwards, giving a comforting

but very misleading impression of steady growth, which was

commonly attributed to technology, when in fact it was mainly

an artifact of reporting practice. But the luxury of underreporting

is fading fast, forcing the major companies to merge and, in

some cases, revise downward their reported reserves. In part, this

situation reflects the aging of the giant fields holding most of the

world’s oil — it being clearly easier to underreport a large field than

a small one. In any event, the revisions have to be backdated to

the original discovery to obtain a valid discovery trend.

The Organization of Petroleum Exporting Countries, for its part,

announced enormous overnight reserve increases in the 1980s. At first,

these increases seemed to be a correction of the underreporting inherited

from the foreign companies before they were nationalized. But it

now transpires that they may have started reporting the total found,

not the remaining reserves, explaining why the official numbers have

barely changed since, despite massive subsequent production. At all

events, the dataset is grossly unreliable, with as much as 300 Gb (billion

barrels) being in doubt.

Compounding the problem is confusion over what was measured.

There are many different categories of oil, each with its own

costs, characteristics and, above all, its own depletion profile.

Producing oil from a free-flowing Middle East well is not the

same as digging up a tar sand in Canada with a shovel, albeit a

big one. Some types are cheap, easy and fast to produce, whereas

others are the precise opposite. It is, therefore, useful to identify

 

 

regular conventional oil, defining it to exclude oil from coal and

shale, bitumen and heavy oil, deepwater and polar oil, as well as

the liquids that are extracted from gasfields in specialized plants.

Regular conventional oil has supplied most to-date and will dominate

all supply far into the future.

Unraveling all of these confusions, so far as is possible,

suggests that the status of depletion for regular conventional is

as follows (to be generously rounded):

 

 

Produced to-date (end 2005) ................................... 968 Gb

Future Production ................................... 882 Gb

From known fields 760 Gb

From new finds 122 Gb

Total .........................................................1,850 Gb

 

 

Figure 1 shows the discovery record, using properly backdated

industry data published by ExxonMobil (Longwell, H., “The Future

of the Oil and Gas Industry: Past Approaches, New Challenges,” World

Energy, 5:3 2002: 100-104). World discovery has evidently been in

decline since 1964, despite a worldwide search always aimed at the

biggest and best prospects; despite all the many advances in technology

and geological knowledge; and despite a favorable economic

regime whereby most of the cost of exploration was offset

against taxable income. It means that there is no good reason to

expect the downward trend to change direction. The world started

using more than it found in 1981, and last year found only

about one barrel of regular conventional oil for every five or six consumed.

Oil has to be found before it can be produced, which

means that production in any country, region and eventually the

world as a whole has to mirror discovery after a time lapse.

Although the skills of a detective are needed to collect the evidence

and analyze it properly, we may be confident that the

depletion profile in figure 2 represents a realistic general assessment

sufficient for planning purposes.

In short, the Second Half of the Age of Oil now dawns. It will be

marked by the decline of oil and all that depends upon it. Gas, which

has a rather different depletion profile, will also in due course head

into steep decline.

Preparing for Declining Supply

Much study and debate has been dedicated to determining the

date of peak production, but that really misses the point. It is not

an isolated or high peak, but merely the maximum value on a gentle

curve. What matters, and matters gravely, is the vision of the

long, remorseless and relentless decline that comes into sight on

the other side of the peak.

That said, the peak does represent an unprecedented turningpoint

of magnitude marking the shift from growth to decline. It

<
Publicité
p align="left">is very difficult for classical economists to accept this, as the

notion that the market must always deliver is deeply entrenched

in their thinking. They rightly remind us that the Stone Age did

not end for want of stones as man found bronze, iron and steel

as better materials for tools and weapons. But the decline of oil

arises from natural depletion not from the entry of better substitutes.

Many people try to reassure themselves in the belief that

new technology or new investment will keep the oil and gas

flowing, but there is an irony about depleting a finite resource: The

better you are at doing the job, the sooner it ends.

The transition to decline threatens to be a time of great international

tension. The major consuming countries will vie with each

other for access to supply, most of which lies in just five countries bordering

the Persian Gulf, one of which has already been invaded.

The conditions that will unfold during the Second Half of the

Age of Oil appear dire, and for that very reason deserve serious

attention (see Campbell’s 2005 book, Oil Crisis, Multi-Science Publishing,

ISBN 0906522-39-0, for further discussion). It looks as if virtually

all companies quoted on the stock exchange are overvalued

insofar as their accounts tacitly assume a business-as-usual

supply of energy, which is no longer justified. Does this point to

a second Great Depression, perhaps accompanied by rampant

inflation to remove excess financial capital as debt loses its oilbased

collateral? Does it mark the end of economics as presently

understood? The world’s population expanded six-fold exactly

in parallel with oil, posing the awful question of how many

people the planet can support without oil.

These are serious questions, and there is certainly no solution

in terms of finding enough new oil and gas to prolong the past

epoch. But there certainly are responses by which to plan and prepare.

It is not difficult to formulate some useful steps:

 

 

 

 

1) Evaluate the Real Resource Situation. In this way, we can

avoid being misled by erroneous forecasts promulgated by international

organizations that are under political pressures.

 

2) Educate Users. Undertake a massive program of public

education, so that everyone may become more energy-conscious

and find ways to be less wasteful. Eventually, an efficiency factor

could be incorporated into utility and fuel charges to penalize the

wasteful and encourage the efficient. The transport system, in particular,

demands urgent attention.

 

3) Ramp Up Renewable Energy. Encourage the rapid development

of renewable energies from tide, wave, solar, wind and

other sources, including the growing of energy crops.

 

4) Reconsider Nuclear Energy. Reevaluate the nuclear option,

provided that it can be made safe and the waste-disposal issue can

be resolved.

 

5) Reduce Imports to Match Depletion Rates. Arrange for

importers to cut their oil imports to match world depletion rates,

namely annual production as a percent of what is left, currently

standing at 2 to 3 percent.

Of these, perhaps the last item deserves most attention. Such a policy

would have the effect of reducing world oil prices by putting

demand into balance with supply. The poor countries of the world

would be able to afford their minimal needs, and profiteering from

shortage would be avoided. The cost of producing oil has not changed

materially, so the high prices reflect profiting from shortage, especially

by Middle East governments. That in turn gives rise to massive

destabilizing financial flows threatening an already fragile system.

Above all, it would force the consumers to face the limits

imposed by nature. There are several options for practical implementation,

but some form of rationing would seem to be the

fairest (e.g., David Fleming’s proposed system for tradable energy

quotas, described at www.teqs.net). Energy might even develop into

a form of currency. Whereas the Kyoto Protocol on climate change

requires universal acceptance to work, an Oil Depletion Protocol

would not be so dependent, because the countries that adopted its

measures would soon find themselves having an enormous competitive

advantage over those that continue to live in the past.

Despite the challenges, we may hope at the end of the day that

a new benign age will unfold, as people again come to live in communities

with a better respect for themselves, their neighbors and the

environment in which nature has ordained them to live. Leading happier

and simpler lives, mainly in rural circumstances, they may look

back and realize that oil, and the excessive free energy it released from

fossil sunshine, had been more of a curse than a blessing.

 

C.J. Campbell is the chairman and founder of the Association for

the Study of Peak Oil and Gas (ASPO), which is expanding throughout

the world. He started his career in the oil industry as an exploration

geologist, ending up as an executive vice-president. His career took

him to many countries, giving him a breadth of experience on which

his views are based. He is the author of five books on oil depletion as

well as many scientific and other publications, being now in demand

for radio and TV. Contact him at aspotwo@eircom.net.

There is an irony about depleting a finite resource:

The better you are at doing the job, the sooner it ends.

Imagine the United States a century from now, as a society

that produces virtually all of its energy from clean, domestic,

renewable energy resources. What does it look like, and

how is it different from the one we live in today?

In 2106, there are those who bemoan the loss of cheap

oil, who long for the days when a gallon of gasoline cost less

than a gallon of milk. But access to cheap oil came at a steep price:

the price of dependence on countries that were politically unreliable

and economically unstable; the price of climate disruption

and its economic and environmental costs; perhaps even the

price of our principles, as we spoke of promoting democracy while

propping up tyrannical monarchies and other oppressive regimes.

For those of us with no stake in a continued reliance on fossil

fuels, however, the 22nd century holds enormous promise for

world economies, national security and the personal health and

economic well-being of our children and children’s children.

The stark contrast between this new century and the last is
