Four
years ago, on the eve of Sept. 11, 2001, the need to reduce radically
our reliance on oil was not clear to many and, in any case, the path of
doing so seemed a long and difficult one. Today, both assumptions are
being undermined by the risks of the post-9/11 world and by technological
progress in fuel efficiency and alternative fuels.
A single well-designed attack on the petroleum infrastructure in the Middle
East could send oil to well over $100 per barrel and devastate the world's
economy. That reality, among other risks, and the fact that our current
transportation infrastructure is locked in to oil, should be sufficient
to convince any objective observer that oil dependence today creates serious
and pressing dangers for the United States and other oil-importing nations.
Dependence on petroleum and its products for the lion's share of the world's
transportation fuel creates special dangers in our time. These dangers
are all driven by rigidities and potential vulnerabilities that have become
serious problems because of the geopolitical realities of the early 21st
century.

Gulf. This politically unstable region is home to the lion's
share of the world's remaining petroleum reserves. |
Those who reason about these issues solely on the basis of abstract economic
models that are designed to ignore such geopolitical realities will find
much to disagree with in what follows. Although such models have utility
in assessing the importance of more or less purely economic factors in
the long run, as Lord Keynes famously remarked, "In the long run, we are
all dead."
The current transportation infrastructure is committed to oil and oil-compatible
products. There is a range of fuels that can be used to produce electricity
and heat and that can be used for other industrial uses, but petroleum
and its products dominate the fuel market for vehicular transportation.
Neither the use of natural gas in buses and other fleet vehicles nor the
addition of corn-derived ethanol to gasoline in some states has appreciably
affected petroleum's dominance of the transportation fuel market.
That dependence leaves us vulnerable. The Greater Middle East will continue
to be the low-cost and dominant petroleum producer for the foreseeable
future. The region is home to around two-thirds of the world's proven
reserves of conventional oil. Almost half the world's reserves are in
just Saudi Arabia, Iraq, and Iran. The Greater Middle East will inevitably
have to meet a growing percentage of world oil demand. This demand is
expected to increase by more than 50 percent in the next two decades,
from 78 million barrels per day in 2002 to 118 MBD in 2025, according
to the U.S. Energy Information Administration. Much of the increase in
demand is expected to come from China and India.
One need not argue that world oil production has peaked to see that this
puts a substantial strain on the global oil system. It will mean higher
prices and potential supply disruptions and will put considerable leverage
in the hands of governments in the Greater Middle Eastas well as
in those of other oil-exporting states, such as Russia, Venezuela, and
Nigeria. Deep-water drilling and other opportunities for increases in
supply of conventional oil may provide important increases in supply,
but are unlikely to change this basic picture.
Other production, perhaps from unconventional sources such as tar sands
in Alberta or shale in the American West, may come on line. But these
are relatively costly. Low-cost producers, particularly Saudi Arabia,
could increase production, drop prices for a time, and undermine the economic
viability of the higher-cost competitors. This occurred in the mid-1980s.
For the foreseeable future, as long as vehicular transportation is dominated
by oil as it is today, the Greater Middle East, and especially Saudi Arabia,
will remain in the driver's seat.
In addition, the petroleum infrastructure is highly vulnerable to terrorist
and other attacks. The radical Islamist movement (including but not exclusively
al Qaeda) has, on a number of occasions, explicitly called for worldwide
attacks on the petroleum infrastructure and has carried out some in the
Greater Middle East. A well-planned attack could take some six million
barrels per day off the market for a year or more, sending petroleum prices
over $100 per barrel and severely damaging much of the world's economy.
Domestic infrastructure in the West is not immune from such disruption.
We are now experiencing the many tragedies caused by Hurricane Katrina.
The devastation includes significant damage to the oil infrastructure
in the Gulf of Mexico with consequent shortages, whose duration is as
yet unclear. The recent accident in the Texas City refinery producing
multiple fatalitiespoints out potential infrastructure vulnerabilities.
The Trans-Alaska Pipeline has been subject to several amateurish attacks
that have taken it briefly out of commission; a seriously planned attack
on it could be far more devastating.
In view of these overall infrastructure vulnerabilities, we do not suggest
that policy should focus exclusively on petroleum imports, although such
infrastructure vulnerabilities are likely to be the most severe in the
Greater Middle East. It is there that terrorists have the easiest access
and the largest proportion of proven oil reserves, and low-cost production
is also located there. Nor do we hold the view that by changing trade
patterns anything particular is accomplished. To a first approximation,
there is one worldwide oil market and it is not generally useful for the
U.S., for example, to import less from the Greater Middle East and for
others then to import more from there. In effect, all of us oil-importing
countries are in this together.
The possibility also exists, particularly under regimes that could come
to power in the Greater Middle East, of embargoes or other disruptions
of supply. It is often said that whoever governs the oil-rich nations
of the Greater Middle East will need to sell their oil. This is not true,
however, if the rulers choose to try to live, for most purposes, in the
eighth century. Osama Bin Laden has advocated, for example, major reductions
in oil production.

pipelines (top) are virtually undefended. |

Even if one is optimistic that democracy and the rule of law will spread
in the Greater Middle East and that this will lead after a time to more
peaceful and stable societies there, substantial risk exists that for
some time the region will be characterized by chaotic change and unpredictable
governmental behavior. Reform, particularly if it is hesitant, has in
a number of cases been trumped by radical takeoverswitness the Jacobins
and the Bolsheviks. There is no reason to believe that the Greater Middle
East is immune from these sorts of historic risks.
Wealth transfers from oil have been used, and continue to be used, to
fund terrorism and its ideological support. Estimates of the amount spent
by the Saudis in the last 30 years spreading Wahhabi beliefs throughout
the world vary from $70 billion to $100 billion. Furthermore, some oil-rich
families of the Greater Middle East fund terrorist groups directly. Whether
in lectures in the madrassas of Pakistan, in textbooks printed by Wahhabis
for Indonesian schoolchildren, or on bookshelves of mosques in the U.S.,
the hatred spread by Wahhabis and funded by oil is evident and influential.
It is sometimes contended that we should not seek substitutes for oil
because disruption of the flow of funds to the Greater Middle East could
further radicalize the population of some states there. The solution,
however, surely lies in helping these states diversify their economies
over time, not in perpetually acquiescing to the economic rent they collect
from oil exports and to the uses to which these revenues are put.
The dangers listed above in turn give rise to two proposed directions
for government policy in order rapidly to reduce our vulnerability. In
both cases, we believe that existing technology should be used; that is,
technology already in the market or that can be so in the very near future
and is compatible with the existing transportation infrastructure. To
this end, government policies in the United States and other oil-importing
countries should encourage a shift to substantially more fuel-efficient
vehicles, including fostering battery development for plug-in hybrid vehicles;
and encourage biofuels and other alternative fuels that wherever possible
can be derived from waste products.
Three currently available technologies stand out to improve vehicle mileage:
diesel engines, hybrid gasoline electric drivetrains, and lightweight
carbon composite construction. A modification to hybrids now on the market
could permit them to become "plug-in hybrids," drawing power from the
electricity grid at night and using electricity for short trips.
According to Peter Huber and Mark Mills in their recent book, The Bottomless
Well, the "vast majority of the most fuel-hungry trips are under six
miles," which can be handled by current nickel-metal hydride battery capacity.
Other experts, however, emphasize that any battery used in a plug-in hybrid
must be capable of taking daily charging without being damaged and be
capable of powering the vehicle at an adequate speed. By most assessments,
some battery development will be necessary.
Such development should have the highest research and development priority
because it promises to revolutionize transportation economics and to have
a dramatic effect on the problems caused by oil dependence.

With a plug-in hybrid vehicle one has the advantage of an electric car,
but not the disadvantage. Electric cars cannot be recharged if their batteries
run down at some spot away from electric power. But since hybrids have
tanks containing liquid fuel (gasoline, ethanol, diesel, or renewable
diesel), plug-in hybrids have no such disadvantage. Moreover, the attractiveness
to the consumer of being able to use electricity from overnight charging
for a substantial share of the day's driving is stunning. The average
residential price of electricity in the United States is about 8.5 cents
per kilowatt-hour.
Taking into account the different tank-to-wheel efficiency of liquid-fueled
and electric propulsion, 8.5 cents per kWh electricity is roughly equivalent
to gasoline at $1 per gallon. Moreover, many utilities sell off-peak power
for 2 to 4 cents per kWhthe equivalent of gasoline costing 25 to
50 cents per gallon.
Although the use of off-peak power for plug-in hybrids should not initially
require substantial new investments in electricity generation, greater
reliance on electricity for transportation should lead us to look particularly
to the security of the electricity grid and the fuel used to generate
that power. A 2002 report of the National Academies of Science, Engineering,
and Medicine ("Making the Nation Safer") emphasized particularly the need
to improve the security of transformers and of the supervisory control
and data acquisition, or SCADA, systems in the face of terrorist threats.
The National Commission on Energy Policy has seconded those concerns.
With or without the advent of plug-in hybrids, these electricity grid
vulner- abilities require urgent attention.
If even one of these new transportation technologies is moved promptly
into the market, the reduction in oil dependence could be substantial.
If several begin to be successfully introduced into large-scale use, the
reduction could be stunning. For example, if a 50 miles-per-gallon hybrid
gasoline-electric vehicle on the road today were constructed from carbon
composites, its fuel efficiency would be doubled.
If it were to operate on 85 percent cellulosic ethanol or a similar proportion
of biodiesel or renewable diesel, it would be achieving hundreds of miles
per gallon of petroleum-derived fuel. If it were a plug-in version operating
on upgraded lithium batteries so that 20- or 30-mile trips could be undertaken
on its overnight charge before it began using liquid fuel at all, one
gallon of fossil petroleum could suffice for around 1,000 miles of travel.
A range of important objectiveseconomic, geopolitical, environmentalwould
be served by our embarking on such a path. Of greatest importance, we
would be substantially more secure.

Drive of the Future?
If concerns about oil security are
going to remake American driving habits, then current owners of
hybrid cars have a head start on their neighbors. But anyone who
thinks this is going to be a grim, eat-your-vegetables experience
should think again. While the original idea when I bought my Toyota
Prius was to save on gasoline, getting used to driving what feels
like a space capsule is another thing altogether.
Driving it is incredibly smooth and it took very little time to
get used to it. I learned in a parking lot that the Prius can be
too stealthy. People are apt to dart in front because they don't
hear you approach. It can be a bit disconcerting to hear the motor
die at a traffic light and be surrounded by utter quiet if there
are no other cars around. The exchange of power from engine to electric
is smooth and effortless.
Living in a small town, my driving involves a lot of stopping and
going, which is where the hybrid shines. I've been able to
get 55 miles per gallon, but my consistent average is 45, with the
difference being travel on the freeway between towns.
Driving this car requires that the ease of starting and stopping
not become too habitual. One time I arrived at home, then realized
I forgot to take down my business mileage. I pushed the Power button,
read the odometer and wrote it down, forgetting to push the Power
to turn it off again. With a silent motor, I never noticed. For
the next few hours I could hear something turning on and off, but
attributed it to the next door neighbor who putters in his garage
with machinery. The next morning, I realized it was the Prius turning
itself on and off in anticipation of my shifting into gear. When
I got into it to drive, the battery was down to the last two clicks
(of eight) in the readout. However, the car took off as usual and
in less than a mile, it had recovered two clicks of charge. In another
mile and a half, it recovered to the top again. I started breathing
again: A new battery is about the cost of the entire car.
One more difference from traditional cars is the use of brakes.
In talking with Dave Hermance, chief engineer at Toyota in Los Angeles,
I learned that all hybrid vehicles use regenerative energy. Toyota
is a little bit more successful in capturing it than others.
The Prius is a 33 kW power machine and deceleration recaptures a
significant portion of the brake energy. The brakes are a little
"grabby," but that was one of the easier lessons to
learn. Keep your heel on the floor and apply the brakes gently.
There is a lot of get-up-and-go in the engine, as I found out when
a woman pulled out in front of me and I had to brake or get out
of the way faster. I opted for the latter and escaped. It was just
another reason to be happy about the decision to get this hybrid
car.
