Green Car Congress -- May 20, 2005
Greenspan on Energy
Alan Greenspan, Chairman of the Federal Reserve Board,
spoke to the Economic Club of New York recently on the
energy situation, calling the oil and gas price surges
of the past two years “the most immediately prominent”
major shocks to the American economy over the past
twenty years.
In the long term, Greenspan is optimistic about the
market’s ability to adjust.
World markets for oil and natural gas have been subject
to a degree of strain over the past year not experienced
for a generation. Increased demand and lagging additions
to productive capacity have combined to eliminate a
significant amount of the slack in energy markets that
was essential in containing energy prices between 1985
and 2000. [...]
But if history is any guide, should higher prices
persist, energy use over time will continue to decline
relative to gross domestic product (GDP). In the wake of
sharply higher prices, the energy intensity of the
United States economy has been reduced about half since
the early 1970s. Much of that displacement was achieved
by 1985. Progress in reducing energy intensity has
continued since then, but at a lessened pace. [...]
With real energy prices again on the rise, more-rapid
decreases in the intensity of use in the years ahead
seem virtually inevitable. As would be expected,
long-term demand elasticities have proved noticeably
higher than those evident in the short term.
Altering the magnitude and manner of U.S. energy
consumption will significantly affect the path of the
U.S. economy over the long term...The recent shift in
expectations, however, has been substantial enough and
persistent enough to direct business-investment
decisions in favor of energy-cost reduction.
Of critical importance will be the extent to which the
more than 200 million light vehicles on U.S. highways,
which consume 11 percent of total world oil production,
become more fuel efficient as vehicle buyers choose the
lower fuel costs of lighter or hybrid vehicles.
Greenspan is, of course, an economist, and reflects the
default economist’s view that rising prices will
stimulate newer technologies and enhanced recovery
leading to additional production (ignoring, to a certain
extent, the geological limitations of a non-renewable
resource—i.e., production peaks).
To be sure, world oil supplies and productive capacity
continue to expand. Major advances in recovery rates
from existing reservoirs have enhanced proved reserves
despite ever-fewer discoveries of major oil fields.
[...]
The failure of oil prices to rise as projected in the
late 1970s is a testament to the power of markets and
the technologies they foster. Today, despite its recent
surge, the average price of crude oil in real terms is
still only three-quarters of the price peak of February
1981. Moreover, the effect of the current surge in oil
prices, though noticeable, is likely to prove less
consequential to economic growth and inflation than in
the 1970s. Since the end of 2003, the rise in the value
of imported oil—essentially a tax on U.S. residents—has
amounted to about ¾ percent of GDP. The effects were far
larger in the crises of the 1970s. But, obviously, the
risk of more-serious negative consequences would
intensify if oil prices were to move materially higher.
Ultimately, however, he turns to alternatives to
conventional crude.
But because of inexorably rising demand, these improved
technologies have been unable to prevent the underlying
long-term prices of oil and natural gas in the United
States from rising.
Conversion of the vast Athabasca oil sands reserves in
Alberta to productive capacity has been slow. But at
current market prices they have become competitive.
Moreover, new technologies are facilitating U.S.
production of so-called unconventional gas reserves,
such as tight sands gas, shale gas, and coalbed methane.
Production from unconventional sources has more than
doubled since 1990 and currently accounts for roughly
one-third of U.S. dry gas production. According to
projections from the Energy Information Administration,
most of the growth in the domestic supply of natural gas
over the next twenty years will come from unconventional
sources. In many respects, the unconventional is
increasingly becoming the conventional.
Not even in the most wildly optimistic projections about
the capabilities of unconventional oil (oil sands,
extra-heavy-oil, shale) does their production offset the
decline in conventional—and more easily produced—crude.
Implicit in his approach is a recognition that the price
band for fuel and energy has made a permanent jump
higher—the unconventional may become conventional, but
it won’t be cheap, nor as plentiful as the “old”
conventional was.
He then turns to the issue of potential substitution,
made more attractive by that rising price band.
Clearly, limited substitution possibilities across fuels
have resulted in persistent cost differentials, but
those very differentials inspire the technologies that,
over time, reduce such limitations. A clear example is
gas-to-liquids (GTL) technology, which converts natural
gas to high-quality naphtha and diesel fuel.
Given the large-scale production facilities that are
currently being contemplated, GTL is poised to become an
increasingly important component of the world’s energy
supply. Current projections of production however remain
modest. GTL promises to add a good measure of
flexibility in the way that natural gas resources are
utilized. In addition, given the concerns over the
long-term adequacy of liquid production capacity from
conventional oil reserves, gas to liquids may provide an
attractive, competitively priced, option for making use
of stranded gas, which, for lack of access to
transportation infrastructure, cannot be brought to
market.
Ultimately, it boils down to the time available to make
the changes that need to be made.
Innovation is already altering the power source of motor
vehicles, and much research is directed at reducing
gasoline requirements. Moreover, new technologies to
preserve existing conventional oil reserves will emerge
in the years ahead. We will begin the transition to the
next major sources of energy perhaps before midcentury
as production from conventional oil reservoirs,
according to central tendency scenarios of the Energy
Information Administration, is projected to peak. In
fact, the development and application of new sources of
energy, especially nonconventional oil, is already in
train. Nonetheless, the transition will take time. We,
and the rest of the world, doubtless will have to live
with the geopolitical and other uncertainties of the oil
markets for some time to come.
We are unable to judge with certainty how technological
possibilities will play out in the future, but we can
say with some assurance that developments in energy
markets will remain central in determining the
longer-run health of our nation’s economy.
If the EIA scenarios to which Greenspan refers are
correct, and peaking occurs more toward mid-century,
then we have a mildly turbulent ride. If, however,
peaking occurs sooner than that, say, in the next few
years as an increasing number of geologists and analysts
are predicting, then the scenario is a very different
one.
And should that be the case, then Greenspan still will
be correct—the market, certainly not policy from
Washington (at least given the current activity on the
energy bill), will drive the transition. But the pain
involved will be much greater than he anticipates.
