Problems
at the Pump
I’m writing in early
May as gasoline prices across the country have begun to rise sharply.
Perhaps it is a result of concerns about Iraq, and prices do fluctuate, but
this may give us a taste of future problems.
An article by an Iranian, Samsam Bakhtiari,
in the April 26 issue of Oil and Gas Journal uses a model of global
oil resources to predict that world oil production will peak around
2006–2007. This is not an isolated prediction, for a number of oil experts
have concluded that peaking will probably occur in this particular decade.
This sort of analysis was pioneered by M. King Hubbert of Shell Oil who in
1956 predicted that oil production in the United States (then 48 states)
would peak around 1969. This was criticized as unduly pessimistic, but
production did reach its maximum in 1970. This does not mean that the world
will run out of oil in a couple of years. About half of the amount present
in the earth when the first oil well was drilled in 1859 is still here. But
at that point oil extraction starts getting more difficult, and the amount
produced each year begins to slowly decline. This will have major economic
and political consequences.
Models and theoretical projections have
limits. They require estimates of the total oil reserves of the planet, and
there could be surprises that would push the date of peaking back a bit. But
we would have to discover about two new fields equivalent to Prudhoe Bay in
Alaska each year to keep up with the game. That isn’t likely for very long.
We would like oil supplies to last longer,
but one sign of maturity is realizing that wishing won’t make it so. New
technologies may enable us to replace oil with other energy sources, but
there is no certainty that this will be feasible on the scales that are
needed. And in the long run we will all be dead, but an oil shortage will
come in the lifetimes of our children and grandchildren.
Religious Aspects
There are also religious expressions of those hopes. God will take care of
us — but God has not promised to supply us with all the oil we want. The
Second Coming might be soon, but I don’t think the parousia is timed to make
sure we have the resources we want right up to the end. More serious
theological and ethical reflection about resources, and oil in particular,
will consider not only God’s provision for our needs but also our
responsibility for stewardship — of the earth and of resources for our
descendants.
We could criticize the apparent lack of
stewardship of oil that our generation and previous ones have exercised. A
resource that developed over more than a hundred million years has been half
used up in less than 150 years! But, while this oil could have been used
more efficiently, one can argue that it was needed to be used if an advanced
technological society was to be developed in large parts of the world. It is
more urgent to think about the forms that our stewardship should be taking
now and in the future.
Individuals can practice conservation, and
congregations should encourage such efforts. “What kind of car would Jesus
drive?” really isn’t a bad thing to think about.
And demand for oil would be lessened if more
Americans could get rid of their attitude that “only wusses ride the busses”
and other public transportation.
In a scientific and technological world the
church, more than ever, needs to have an adequate social ethic and be
prepared to speak up in the political and economic arenas. The problem has
to be dealt with primarily at a national and even global level. The oil
supply is not going to be prolonged for very long by car pooling.
What types of policies should be advocated?
Nothing we can do right now is going to have a significant effect on energy
supplies immediately. We may be in for some at least moderately tough times
as far as prices for gas and home heating oil are concerned. A church that
speaks of the cost of discipleship ought to be able to talk realistically
about this.
Some moderation of our energy use is in
order, but there are limits to what can be done without returning to a
pre-industrial society. (Whatever romantics may think, this would not be the
good old days for most people.) Clearly we need to find alternatives to oil
as an energy source. It is also required for many petrochemicals — plastics,
fertilizer, and so on — and we shouldn’t just keep burning it.

Alternative Energy Sources
Many Americans are fearful about energy from fission of uranium or
plutonium, and we do need to be careful with it. The fact that some nuclear
wastes remain dangerous for tens of thousands of years is enough reason for
caution. But a lot of the fear of nuclear power is excessive and stems from
ignorance. The minor accident at Three Mile Island and even the Chernobyl
disaster have to be compared with the deaths, injuries, and environmental
damage from fossil fuels (fires, smog, greenhouse gases, oil spills, etc.).
Controlled fusion of light nuclei is a more
attractive prospect, but there is one major problem: In spite of intensive
work for fifty years, we don’t know how to do it. It always seems that
controlled fusion as a realistic source of power is twenty or thirty years
in the future. Perhaps it will come, but the fact that stars can do it
doesn’t guarantee that we can.
Solar power heads the list of environmentally
friendly alternatives. It can make a contribution in some areas but will not
be able to bear the full load of a modern technological society. In any
case, all the alternatives mentioned have the drawback relative to oil that
they are not convenient for personal transportation. Here the “hydrogen
economy” may come into play. Hydrogen burns in oxygen to form water and
release energy, and the same process can be carried out by a fuel cell,
which can be used to power a car.
But earth has no mines of pure hydrogen! We
would get that fuel by using the same amount of energy to break water down
into hydrogen and oxygen. So hydrogen would essentially be a way of storing
and making portable the energy from other sources.
I have not been so foolish as to try to solve
the oil crisis in 1,200 words, and I have not mentioned all the
possibilities. I do encourage congregations and larger expressions of the
church to engage faithfully and realistically with issues of environmental
stewardship and social justice raised by our need for energy.
Kenneth S. Deffeyes, Hubbert’s Peak: The
Impending World Oil Shortage (Princeton,2001) is a lively introduction
to oil exploration and extraction and future prospects. Colin J. Campbell
and Jean H. Laherrère, “The End of Cheap Oil,” Scientific American,
March 1998, and Glenn Morton’s Web site
http://home.entouch.net/dmd/Oilcrisis.htm provide further information.
The titles of David Bodansky, Nuclear Energy (American Institute of
Physics, 1996), and Matthew L.Wald, “Questions about a Hydrogen Economy,”
Scientific American, May 2004, are self-explanatory.
