Why GAO Did This Study: 

Soaring retail gasoline prices have garnered extensive media attention 
and generated considerable public anxiety in recent months, 
particularly in the aftermath of Hurricane Katrina. Prices in many 
areas hit by the hurricane saw retail gasoline prices increase to over 
$3.00 per gallon, and in one reported case to almost $6.00 per gallon, 
with some gasoline stations running out of gasoline entirely. 

The availability of relatively inexpensive gasoline over past decades 
has helped foster economic growth and prosperity in the United States, 
so large price increases, especially if sustained over a long period, 
pose long-term challenges to the economy and consumers. 

This testimony, as requested, addresses factors that help explain how 
gasoline prices are determined and what key factors will likely 
influence trends in future gasoline prices. 

What GAO Found: 

Crude oil prices and gasoline prices are inherently linked, because 
crude oil is the primary raw material from which gasoline and other 
petroleum products are produced. In the past year, crude oil prices 
have risen significantly—from August 31, 2004 to August 31, 2005, the 
price of West Texas Intermediate crude oil, a benchmark for 
international oil prices, rose by almost $27 per barrel, an increase of 
almost 64 percent. Over about the same period, average retail prices 
for regular gasoline rose nationally from $1.87 to $2.61 per gallon, an 
increase of about 40 percent. Major upward and downward movements of 
crude oil prices are generally mirrored by movements in the same 
direction by gasoline prices. However, based on recent events, at least 
in the short term, this historical trend has not held, and retail 
prices have risen faster than crude oil prices. 

While crude oil is a fundamental determinant of gasoline prices, a 
number of other factors also play a role in determining how gasoline 
prices vary across different locations and over time. For example, 
refinery capacity in the United States has, in recent years, not 
expanded at the same pace as demand for gasoline and other petroleum 
products. During the same period we have imported larger and larger 
volumes of gasoline from Europe, Canada, and other countries. Further, 
the American Petroleum Institute has recently reported that U.S. 
average refinery capacity utilization has increased to 92 percent. As a 
result, domestic refineries have little room to expand production in 
the event of a temporary supply shortfall. 

Gasoline prices may also be affected by unexpected refinery outages or 
accidents that significantly disrupt the delivery of gasoline supply. 
Most recently, Hurricane Katrina hit the Gulf Coast, doing tremendous 
damage to homes, businesses, and physical infrastructure, including 
roads; electricity transmission lines; and oil producing, refining, and 
pipeline facilities. Because the Gulf Coast refining region is a net 
exporter of petroleum products to all other regions of the country, 
retail gasoline prices in many parts of the nation rose dramatically. 
Average retail gasoline prices increased 45 cents per gallon between 
August 29 and September 5. The average price for a gallon of regular 
gasoline on September 5 was $3.07, the highest nominal price ever. 

Future gasoline prices will reflect the world supply and demand 
balance. Globally, if demand for oil and petroleum products continues 
to rise, supply will need to keep pace. The challenge is to boost 
supply and reduce demand. We need to choose wisely and we need to act 
soon.

Mr. Chairman and Members of the Committee: 

I am pleased to participate in the Committee's hearing to discuss 
current gasoline prices and the factors that will likely influence 
trends in those prices. Soaring retail gasoline prices have garnered 
extensive media attention and generated considerable public anxiety in 
recent months, particularly in the aftermath of Hurricane Katrina. 
Prices in many areas hit by the hurricane saw retail gasoline prices 
increase to over $3.00 per gallon, and in one reported case to almost 
$6.00 per gallon, with some gasoline stations running out of gasoline 
entirely. In addition, retail gasoline prices have shot up in many 
areas of the country that were not directly affected by the hurricane. 
It was not uncommon to see pump prices rise not just daily, but 
multiple times in the same day. Overall, gasoline prices have been 
significantly higher this year than last, costing American consumers 
considerably. According to the Department of Energy's Energy 
Information Administration (EIA), nationally, each additional ten cents 
per gallon of gasoline adds about $14 billion to America's annual 
gasoline bill. 

The availability of relatively inexpensive gasoline over past decades 
has helped foster economic growth and prosperity in the United States. 
However, large price increases, especially if sustained over a long 
period, pose long-term challenges to the economy and consumers. 
Importantly, some recent analyses suggest that gasoline prices may stay 
at today's relatively high level or even increase significantly in the 
future. In contrast, others suggest that prices may fall as oil 
companies invest in more crude oil producing capacity and as consumers 
respond to higher prices by adopting more energy-efficient practices. 
Regardless of what happens in the future, the impact of gasoline prices 
is felt in virtually every sector of the U.S. economy and when prices 
increase sharply, as they have in recent months, consumers feel it 
immediately and are reminded every time they fill up their tanks. 

It is therefore essential to understand the market for gasoline. In 
this context, you asked us to discuss (1) how gasoline prices are 
determined and (2) what key factors will likely influence trends in 
future gasoline prices?

To respond to your questions, we relied heavily on the gasoline primer, 
"Motor Fuels: Understanding the Factors That Influence the Retail Price 
of Gasoline,"[Footnote 1] and 17 other GAO products on gasoline prices 
and other aspects of the petroleum products industry. (See Related GAO 
Products at the end of this testimony.) We also collected updated data 
from a number of sources that we deemed reliable. This work was 
performed in accordance with generally accepted government auditing 
standards. 

In summary, our work has shown: 

* Crude oil prices and gasoline prices are inherently linked, because 
crude oil is the primary raw material from which gasoline and other 
petroleum products are produced. In the past year, crude oil prices 
have risen significantly--from August 31, 2004 to August 31, 2005, the 
price of West Texas Intermediate crude oil, a benchmark for 
international oil prices, rose by almost $27 per barrel, an increase of 
almost 64 percent. Over about the same period, average retail prices 
for regular gasoline rose nationally from $1.87 to $2.61 per gallon, an 
increase of about 40 percent. Explanations for the large increase in 
crude oil and gasoline prices include the rapid growth in world demand 
for crude oil and petroleum products, particularly in China and the 
rest of Asia; instability in the Persian Gulf region (the source of a 
large proportion of the world's oil reserves); and actions by the 
Organization of Petroleum Exporting Countries (OPEC) to restrict the 
production of crude oil and thereby increase its price on the world 
market. Figure one illustrates the relationship between crude oil and 
gasoline prices over the past three decades. The figure shows that 
major upward and downward movements of crude oil prices are generally 
mirrored by movements in the same direction by gasoline prices. 
However, based on recent events, at least in the short term, this 
historical trend has not held, and retail prices have risen faster than 
crude oil prices.

* While the price and availability of crude oil is a fundamental 
determinant of gasoline prices, a number of other factors also play a 
role in determining how gasoline prices vary across different locations 
and over time. For example, refinery capacity in the United States has 
not expanded at the same pace as demand for gasoline and other 
petroleum products in recent years. During the same period the United 
States has imported larger and larger volumes of gasoline from Europe, 
Canada, and other countries. The American Petroleum Institute has 
recently reported that U.S. average refinery capacity utilization has 
increased to 92 percent. As a result, domestic refineries have little 
room to expand production in the event of a temporary supply shortfall. 
Further, the fact that imported gasoline comes from farther away than 
domestically produced gasoline means that when supply disruptions occur 
in the United States, it might take longer to get replacement gasoline 
than if we had excess refining capacity in the United States, and this 
could cause gasoline prices to rise and stay high until these new 
supplies can reach the market. 

* Gasoline inventories maintained by refiners or marketers of gasoline 
can also have an impact on prices. As with trends in a number of other 
industries, the petroleum products industry has seen a general downward 
trend in the level of gasoline inventories in the United States. Lower 
levels of inventories may cause prices to be more volatile because when 
a supply disruption occurs, there are fewer stocks of readily available 
gasoline to draw from, putting upward pressure on prices. Regulatory 
factors also play a role. For example, in order to meet national air 
quality standards under the Clean Air Act, as amended, many states have 
adopted the use of special gasoline blends--so-called "Boutique Fuels." 
Many experts have concluded that the proliferation of these special 
gasoline blends has caused gasoline prices to rise and/or become more 
volatile, especially in regions such as California that use unique 
blends of gasoline, because the fuels have increased the complexity and 
costs associated with supplying gasoline to all the different markets. 
Finally, the structure of the gasoline market can play a role in 
determining prices. For example, we recently reported that some mergers 
of oil companies during the 1990s led to reduced competition among 
gasoline suppliers and may have been responsible for an increase in 
gasoline prices by as much as 2 cents per gallon on average, with 
boutique fuels increasing from between 1 to 7 cents per gallon. 

* Gasoline prices may also be affected by unexpected refinery outages 
or accidents that significantly disrupt the delivery of gasoline 
supply. Most recently, Hurricane Katrina hit the Gulf Coast, doing 
tremendous damage to homes, businesses, and physical infrastructure, 
including roads; electricity transmission lines; and oil producing, 
refining, and pipeline facilities. The DOE reported on August 31, 2005 
that as many as 2.3 million customers were without electricity in 
Louisiana, Mississippi, Alabama, Florida, and Georgia. The DOE further 
reported that 21 refineries in affected states were either shut down or 
operating at reduced capacity in the aftermath of the hurricane. This 
amounted to a reduction of over 10 percent of the nation's total 
refining capacity. Two petroleum product pipelines that serve the 
Midwest and East Coast from Gulf Coast refineries were also out. In 
addition, the Minerals Management Service in the Department of the 
Interior reported that as of September 1, 2005, over 90 percent of 
crude oil production in the Gulf of Mexico was out of operation. 
Because the Gulf Coast refining region is a net exporter of petroleum 
products to all other regions of the country, retail gasoline prices in 
many parts of the nation rose dramatically. Average retail gasoline 
prices increased 45 cents per gallon between August 29 and September 5. 
The average price for a gallon of regular gasoline on September 5 was 
$3.07, the highest nominal price ever. In addition, gasoline stations 
faced large increases in wholesale gasoline prices, and some even 
reported running out of gasoline. The spot price for wholesale gasoline 
delivered to New York Harbor rose by about $0.78 per gallon between 
August 26 and August 30. Gasoline supply is recovering in the wake of 
the storm, however, and prices have begun to decrease. Between 
September 5 and September 12, average gasoline prices decreased 11 
cents to $2.96 per gallon. Gasoline production increased dramatically 
over this time, rising by more than 400,000 barrels per day as most of 
the refineries shut down after the storm resumed production. Until 
production, refining, and pipeline facilities are fully operating at 
normal levels, prices are expected to continue to be higher in affected 
areas. Coming as this has on the heels of a period of high crude oil 
prices and a tight balance worldwide between petroleum demand and 
supply, the effects of the hurricane illustrate the volatility of 
gasoline prices given the vulnerability of the gasoline infrastructure 
to natural or other disruptions. 

* Future gasoline prices will reflect the world supply and demand 
balance. If demand for oil and petroleum products continues to rise as 
it has in past years, then oil supply will have to expand significantly 
to keep up. The EIA projects that world demand for crude oil will rise 
by at least 25 percent by the year 2025. However, world surplus crude 
oil production capacity--the amount by which oil production can be 
increased in the short run without installing more drilling equipment 
or developing new oil fields--is currently very small. Moreover, many 
of the world's known and easily accessible crude oil deposits have 
already been developed and many of these are experiencing declining 
volumes as the fields become depleted. Other new sources may be more 
expensive to develop. For example, there are large stores of crude oil 
in tar sands and oil shale, or potentially beneath deep water in the 
ocean, but these sources are more costly to extract and process than 
many of the sources of oil that we have already tapped. If developing, 
extracting, and refining new sources of crude oil are more costly than 
extracting and refining oil from existing fields, crude oil and 
petroleum product prices likely will rise to make these activities 
economically feasible. If, on the other hand, technological innovations 
improve the ability to extract and process oil, this will increase the 
available future supply and may ease pressure on petroleum product 
prices. 

* Although demand for crude oil is projected to increase, it could fall 
below current expectations if consumers choose more energy efficient 
products or otherwise conserve more energy. Such a reduction in demand 
could lead to lower-than-expected future prices. For example, in 
response to high gasoline prices in the United States, in the 1980s 
many consumers chose to switch to smaller or more fuel-efficient 
vehicles, which reduced demand for gasoline. Environmental issues could 
also have an impact on world crude oil and petroleum product prices. 
For example, international efforts to reduce greenhouse emissions could 
cause reductions in demand for crude oil and petroleum products as more 
fuel-efficient processes are adopted or as cleaner sources of energy 
are developed. Additional factors that will likely influence future oil 
and gasoline prices include geopolitical issues, such as the stability 
of the Middle East; the valuation of the U.S. dollar in world currency 
markets; and the pace of development of alternative energy supplies, 
such as hydrogen fuel cell technology. 

Background: 

In 2004, the United States consumed about 20.5 million barrels per day 
of crude oil accounting for roughly 25 percent of world oil production. 
A great deal of the crude oil consumed in this country goes into 
production of gasoline and, as a nation, we use about 45 percent of all 
gasoline produced in the world.[Footnote 2] Products made from crude 
oil--petroleum products, including gasoline--have been instrumental in 
the development of our modern lifestyle. In particular, gasoline, 
diesel, and jet fuel have provided the nation with affordable fuel for 
automobiles, trucks, airplanes and other forms of public and goods 
transportation. Together, these fuels account for over 98 percent of 
the U.S. transportation sector's fuel consumption. In addition, 
petroleum products are used as raw materials in manufacturing and 
industry; for heating homes and businesses; and, in small amounts, for 
generating electric power. Gasoline use alone constitutes about 44 
percent of our consumption of petroleum products in the United States, 
so when gasoline prices rise, as they have in recent months, the 
effects are felt throughout the country, increasing the costs of 
producing and delivering basic retail goods and making it more 
expensive to commute to work. It is often the case that prices of other 
petroleum products also increase at the same time and for the same 
reasons that gasoline prices rise. For example, today's high gasoline 
prices are mirrored by high jet fuel prices, creating financial 
pressure on airline companies, some of which are currently in the midst 
of economic difficulties. Gasoline prices vary a great deal over time. 
For example, in the period January 1, 1995 through August 29, 2005, the 
national average price for a gallon of regular grade gasoline has been 
as low as $1.10 and as high as $2.80 without adjusting for inflation. 

The future path of gasoline prices is difficult to predict, but it is 
clear that the use of petroleum products worldwide is going to increase 
for the near term and maybe beyond. Some analysts have predicted much 
higher crude oil prices--and as a result, higher prices for petroleum 
products--while others expect prices to moderate as producers respond 
to high prices by producing more crude oil and consumers respond by 
conserving more, and investing in more energy-efficient cars and other 
products. In either case, the price of gasoline will continue to be an 
important factor affecting the household budgets of individual 
Americans for the foreseeable future and therefore, it is important to 
understand how prices are determined so that consumers can make wise 
choices. 

Gasoline Prices Are Determined by the Price of Crude Oil and a Number 
of Other Factors: 

Crude oil prices directly affect the price of gasoline, because crude 
oil is the primary raw material from which gasoline is produced. For 
example, according to our analysis of EIA data, in 2004 crude oil 
accounted for about 48 percent of the price of a gallon of gasoline on 
average in the United States. When crude oil prices rise, as they have 
over the past year, refiners find their cost of producing gasoline also 
rises, and in general, these higher costs are passed on to consumers in 
the form of higher gasoline prices at the pump. However, based on 
recent events, at least in the short term, this historical trend has 
not held, and retail prices have risen faster than crude oil prices. 
Figure 2 illustrates the importance of crude oil in the price of 
gasoline. The figure also shows that taxes, refining, and distribution 
and marketing also play important roles.[Footnote 3]

2004):

[End of figure]

Because crude oil is the primary raw material used in the production of 
gasoline, understanding what determines gasoline prices requires 
examining how crude oil prices are set. Overall, the price of crude oil 
is determined by the balance between world demand and supply. A major 
cause of rising crude oil prices in recent months has been rapid growth 
in world demand, without a similar growth in available supplies. In 
particular, the economy of China has grown rapidly in recent years, 
leading to increases in their demand for crude oil. In contrast, oil 
production capacity has grown more slowly, leading to a reduction in 
surplus capacity--the amount of crude oil that is left in the ground, 
but could be extracted on short notice in the event of a supply 
shortfall. EIA has stated that the world's surplus crude oil production 
capacity has fallen to about one million barrels per day, or just over 
one percent of the world's current daily consumption, making the 
balance between world demand and supply of crude oil very tight. This 
tight balance between world crude oil demand and supply means that any 
significant supply disruptions will likely cause prices to rise. Such a 
disruption occurred in Nigeria in October 2004, when a workers' strike 
in Nigeria's oil sector forced world crude oil prices to record highs. 
(Nigeria is the world's seventh largest oil producer, supplying an 
average 2.5 million barrels per day in 2004.)

Another important factor affecting crude oil prices is the behavior of 
the Organization of Petroleum Exporting Countries (OPEC)--members of 
which include Algeria, Indonesia, Iran, Iraq, Kuwait, Libya, Nigeria, 
Qatar, Saudi Arabia, United Arab Emirates, and Venezuela. OPEC members 
produce almost 40 percent of the world's crude oil and control almost 
70 percent of the world's proven oil reserves. In the recent past and 
on numerous other occasions, OPEC members have collectively agreed to 
restrict the production of crude oil in order to increase world prices. 

Turning now to the price of gasoline seen at the pump, it is important 
to discuss the role of taxes. In the United States, on average, taxes 
accounted for 23 percent of what consumers paid for a gallon of 
gasoline in 2004, according to EIA's data. This percentage includes 
estimated federal and average state taxes totaling 44 cents per gallon 
(see figure 3).[Footnote 4] Federal taxes accounted for 18.4 cents of 
this total, while state taxes averaged 25.6 cents per gallon, although 
taxes vary among states. 

Figure 3: Estimated Federal and Average State Gasoline Taxes per Gallon 
(2004): 

[See PDF for image]

[End of figure]

Differences in gasoline taxes across states help explain why gasoline 
prices vary from place to place in the United States. In addition to 
federal taxes that apply across the board, states and, in some cases, 
local jurisdictions also impose taxes and other fees on gasoline that 
add to the price. Figure 4 shows total state and federal gasoline taxes 
for each of the 50 states and the District of Columbia, as of November 
2004. New York, Hawaii, and California have the highest total gasoline 
taxes, while Alaska, Wyoming, and New Jersey have the lowest. While 
differences in taxes affect the price of gasoline, there is no 
consistent relationship between high taxes and high prices. For 
example, on March 7, 2005, gasoline cost $1.91 per gallon in North 
Carolina and $1.98 per gallon in Alaska, even though the taxes paid in 
North Carolina were almost 17 cents per gallon higher. 

Figure 4: Motor Gasoline Taxes as of November 2004: 

[See PDF for image]

Note: According to API, these tax data include applicable state sales 
taxes, gross receipts taxes, and other applicable fees but largely 
exclude local taxes, which may average about 2 cents per gallon 
nationwide. 

[End of figure]

In addition to the cost of crude oil, taxes, refining, and distribution 
and marketing costs, gasoline prices are influenced by a variety of 
other factors. These include refining capacity constraints, low 
inventories, unexpected refinery or pipeline outages, environmental and 
other regulations, and mergers and market power in the oil industry. 

First, domestic refining capacity has not kept pace with growing demand 
for gasoline. As demand has grown faster than domestic refining 
capacity, the United States has imported larger and larger volumes of 
gasoline and other petroleum products from refiners in Europe, Canada, 
and other countries. EIA officials told us that, in general, this 
increase in imports has reflected the availability of gasoline from 
foreign sources at lower cost than could be achieved by building and 
operating additional refining capacity in the United States. However, 
the American Petroleum Institute (API) has recently reported that 
capacity utilization has been high in the U.S. refinery sector. 
Refining capacity has typically averaged over 90 percent, and has 
recently increased to 92 percent--much higher than the rate in many 
other industries that API reports as more typically operating at around 
80 percent of capacity. As a result, domestic refineries have little 
room to expand production in the event of a temporary supply shortfall. 
Furthermore, the fact that imported gasoline comes from farther away 
than domestically produced gasoline means that when supply disruptions 
occur in the United States, it might take longer to get replacement 
gasoline than if we had excess refining capacity in the United States, 
and this could cause gasoline prices to rise and stay high until these 
new supplies can reach the market. 

Second, the level of gasoline inventories can also play an important 
role in determining gasoline prices over time because inventories 
represent the most accessible and available source of supply in the 
event of a production shortfall or increase in demand. Similar to 
trends in other industries, the level of gasoline inventories has been 
falling for a number of years. In part, this reflects a trend in 
business to more closely balance production with demand in order to 
reduce the cost of holding large reserves. However, reduced inventories 
may contribute to increased price volatility, because when unexpected 
supply disruptions or increases in demand occur, there are lower stocks 
of readily available gasoline upon which to draw. This puts upward 
pressure on gasoline prices until new supplies can be refined and 
delivered domestically, or imported from abroad. 

Third, gasoline prices may be affected by unexpected refinery outages 
or accidents that significantly disrupt the delivery of gasoline 
supply. Most recently, Hurricane Katrina hit the Gulf Coast, doing 
tremendous damage to homes, businesses, and physical infrastructure, 
including roads; electricity transmission lines; and oil producing, 
refining, and pipeline facilities. The DOE reported on August 31, 2005 
that as many as 2.3 million customers were without electricity in 
Louisiana, Mississippi, Alabama, Florida, and Georgia. The DOE further 
reported that 21 refineries in affected states were either shut down or 
operating at reduced capacity in the aftermath of the hurricane. The 
refining capacity of the shutdown refineries alone is equivalent to 
over 10 percent of the nation's total refining capacity. Two petroleum 
product pipelines that serve the Midwest and East Coast from Gulf Coast 
refineries were also out. The Minerals Management Service of the 
Department of the Interior reported that as of September 1, 2005, over 
90 percent of crude oil production in the Gulf of Mexico was out of 
operation. Because the Gulf Coast refining region is a net exporter of 
petroleum products to all other regions of the country, retail gasoline 
prices in many parts of the nation have risen dramatically, with news 
reports that many locations have seen prices over $3.00 per gallon, and 
in one reported case to almost $6.00 per gallon. In addition, many 
gasoline stations have reported running out of stocks and have faced 
large increases in wholesale gasoline prices--the spot price for 
wholesale gasoline delivered to New York Harbor rose by about $0.78 per 
gallon between August 26 and August 30. Until production, refining, and 
pipeline facilities are back up and running at normal levels, prices 
are expected to continue to be higher in affected areas. Coming as this 
has on the heels of a period of high crude oil prices and a tight 
balance worldwide between petroleum demand and supply, the effects of 
the hurricane illustrate the volatility of gasoline prices given the 
vulnerability of the gasoline infrastructure to natural or other 
disruptions. Such disruptions also have the potential to adversely 
affect the economy. For example, in 2004, the International Energy 
Agency reported that a $10 increase in the world price of crude oil 
would lead to at least a one half percent reduction in world GDP - 
equivalent to $255 billion - in the year following the price increase. 
The effects on individual countries would vary depending on whether or 
not they are net oil importers and on the level of energy intensity of 
their economies. 

Fourth, regulatory steps to reduce air pollution have also influenced 
gasoline markets and consequently have increased gasoline prices. For 
example, since the 1990 amendments to the Clean Air Act, the use of 
various blends of cleaner-burning gasoline--so-called "boutique fuels-
-has grown as states have adopted the use of such fuels to meet 
national air quality standards. The use of these special blends has 
provided environmental and health benefits by reducing emissions of a 
number of pollutants. However, the proliferation of these special 
gasoline blends has also put stress on the gasoline supply 
infrastructure and has led to increased price volatility because areas 
that use special blends cannot as easily find suitable replacement 
gasoline in the event of a local supply disruption.[Footnote 5]

Finally, we recently reported that industry mergers increased market 
concentration and in some cases caused higher wholesale gasoline prices 
in the United States from the mid-1990s through 2000.[Footnote 6] 
Overall, the report found that the mergers led to price increases 
averaging about 2 cents per gallon on average. For conventional 
gasoline, the predominant type used in the country, the change in the 
wholesale price, due to specific mergers, ranged from a decrease of 
about 1 cent per gallon--due to efficiency gains associated with the 
merger--to an increase of about 5 cents per gallon--attributed to 
increased market power after the merger. For special blends of 
gasoline, wholesale prices increased by from between 1 and 7 cents per 
gallon, depending on location. 

Future Oil and Gasoline Prices Will Reflect Supply/Demand Balance, but 
Technological Change and Conservation Will Also Play a Role: 

Looking into the future, daunting challenges lie ahead in finding, 
developing, and providing sufficient quantities of oil to meet 
projected global demand. For example, according to EIA, world oil 
demand is expected to grow to nearly 103 million barrels per day in 
2025 under low growth assumptions, and may reach as high as 142 million 
barrels per day in 2025--increases of between 25 and 71 percent from 
the 2004 consumption level of 83 million barrels per day. Looking 
further ahead, the rapid pace of economic growth in China and India, 
two of the world's most populous and fastest growing countries, may 
lead to a rapid increase in their demand for crude oil and petroleum 
products. While current consumption of oil by China and India is far 
below that of the United States, it is projected to grow at a far more 
rapid rate. Specifically, EIA's medium-growth projections estimate that 
oil consumption for China and India will each grow by about 4 percent 
annually through 2025, while consumption in the United States is 
projected to grow at an annual rate of 1.5 percent over the same 
period. 

To meet the rising demand for gasoline and other petroleum products, 
new oil deposits will likely be developed and new production facilities 
built. Currently, many of the world's known and easily accessible crude 
oil deposits have already been developed, and many of these are 
experiencing declining volumes as fields become depleted. For example, 
the existing oil fields in California and Alaska have long since 
reached their peak production, necessitating an increasing volume of 
imported crude oil to West Coast refineries. Developing new oil 
deposits may be more costly than in the past, which could put upward 
pressure on crude oil prices and the prices of petroleum products 
derived from it. For example, some large potential new sources, such as 
oil shales, tar sands, and deep-water oil wells, require different and 
more costly extraction methods than are typically needed to extract oil 
from existing fields. In addition, the remaining oil in the ground may 
be heavier and more difficult to refine, necessitating investment in 
additional refinery processes to make gasoline and other petroleum 
products out of this oil. If developing, extracting, and refining new 
sources of crude oil are more costly than extracting and refining oil 
from existing fields, crude oil and petroleum product prices likely 
will rise to make these activities economically feasible. 

On the other hand, technological advances in oil exploration, 
extraction, and refining could mitigate future price increases. In the 
past, advances in seismic technology significantly improved the ability 
of oil exploration companies to map oil deposits, while improvements in 
drilling technology have enabled oil companies to drill in multiple 
directions from a single platform. Together, these advances have 
enabled companies to identify and extract oil more efficiently, 
essentially increasing the supply of oil. Further, refining advances 
over the years have also enabled U.S. refiners to increase the yield of 
gasoline from a given barrel of oil--while the total volume of 
petroleum products has remained relatively constant, refiners have been 
able to get a greater proportion of the more valuable components, such 
as gasoline, out of each barrel, thereby increasing the supply of these 
components. Similar technological improvements in the future that lower 
costs or increase supply of crude oil or refined products would likely 
lead to lower prices for such commodities. 

Innovations that reduce the costs of alternative sources of energy 
could also reduce the demand for crude oil and petroleum products, and 
thereby ease price pressures. For example, hydrogen is the simplest 
element and most plentiful gas in the universe and when used in fuel 
cells produce almost no pollution. In addition, hydrogen fuel cell cars 
are expected to be roughly three times more fuel-efficient than cars 
powered by typical internal combustion engines. Currently, enormous 
technical problems stand in the way of converting America's fleet of 
automobiles from gasoline to hydrogen, including how to produce, store, 
and distribute the flammable gas safely and efficiently, and how to 
build hydrogen cars that people can afford and will want to buy. 
However, there are federal and state initiatives under way as well as 
many private efforts to solve these technical problems, and if they can 
be solved in an economical way in the future, the implications for 
gasoline use could be profound. 

Greater conservation or improved fuel efficiency could also reduce 
future demand for crude oil and petroleum products, thereby leading to 
lower prices. The amount of oil and petroleum products we will consume 
in the future is, ultimately, a matter of choice. Reducing our 
consumption of gasoline by driving smaller, more fuel-efficient cars-- 
as occurred in the 1980s in response to high gasoline prices--would 
reduce future demand for gasoline and put downward pressure on prices. 
For example, the National Academies of Science recently reported that 
if fuel-efficiency standards for cars and light trucks had been raised 
by an additional 15 percent in 2000, gasoline consumption in the year 
2015 would be 10 billion gallons lower than it is expected to be under 
current standards. The Congress established fuel economy standards for 
passenger cars and light trucks in 1975 with the passage of the Energy 
Policy and Conservation Act. While these standards have led to 
increased fuel efficiency for cars and light trucks, in recent years, 
the switch to light trucks has eroded gains in the overall fuel 
efficiency of the fleet of American passenger vehicles. Future 
reductions in demand for gasoline could be achieved if either fuel 
efficiency standards for cars and light trucks are increased, or if 
consumers switch to driving smaller or more fuel-efficient cars. 

The effect of future environmental regulations and international 
initiatives on oil and petroleum products prices is uncertain. On one 
hand, regulations that increase the cost or otherwise limit the 
building of refining and storage capacity may put pressure on prices in 
some localities. For example, the California Energy Commission told us 
the lack of storage capacity for imported crude oil and petroleum 
products may be a severe problem in the future, potentially leading to 
supply disruptions and price volatility. Alternatively, international 
efforts to reduce the generation of greenhouse gas emissions could 
cause reductions in the demand for crude oil and petroleum products 
through the development and use of more fuel-efficient processes and as 
cleaner, lower-emissions fuels are developed and used. 

Moreover, geopolitical factors will likely continue to have an impact 
on the price of crude oil and petroleum product in the future. Because 
crude oil is a global commodity, the price we pay for it can be 
affected by any events that may affect world demand or supply. For 
example, Venezuela--which produces around 2.6 million barrels of crude 
oil per day, and which supplies about 12 percent of total U.S. oil 
imports--is currently experiencing considerable social, economic, and 
political difficulties that have, in the past, impacted oil production. 
Finally, instability in the Middle East, and particularly the Persian 
Gulf, has in the past, caused major disruptions in oil supplies, such 
as occurred toward the end of the first Gulf War, when Kuwaiti oil 
wells were destroyed by Iraq. 

Finally, the value of the U.S. dollar on open currency markets could 
also affect future crude oil prices. For example, because crude oil is 
typically denominated in U.S. dollars, the payments that oil-producing 
countries receive for their oil are also denominated in U.S. dollars. 
As a result, a weak U.S. dollar decreases the value of the oil sold at 
a given price. Some analysts have recently reported in the popular 
press that this devaluation can influence long-term prices in two ways. 
First, oil-producing countries may wish to increase prices for their 
crude oil in order to maintain their purchasing power in the face of a 
weakening U.S. dollar. Secondly, because the dollars that these 
countries have accumulated, which they use, in part, to finance 
additional oil exploration and extraction, are worth less, the costs 
they pay to purchase technology and equipment from other countries 
whose currencies have gained relative to the dollar will increase. Such 
higher costs may deter further expansion of oil production, leading to 
even higher oil prices.[Footnote 7]

Conclusions: 

In closing, the wide-ranging effects of Hurricane Katrina on gasoline 
prices nationwide are a stark illustration of the interconnectedness of 
our petroleum markets and reveal the vulnerability of these markets to 
disruptions, natural or otherwise. Current U.S. energy supplies remain 
highly dependent on fossil energy sources that are costly, largely 
imported, and potentially harmful to the environment. No matter what 
the price of petroleum is, alternative energy options seem always to 
remain uneconomic. Striking a balance between efforts to boost 
petroleum supply, provide incentives for developing of alternative 
energy sources, develop policies and technologies focused on improving 
the fuel efficiency of petroleum burning vehicles, and promote overall 
energy conservation, presents challenges as well as opportunities. 
Clearly, all providers and consumers of energy need to get serious 
about conserving energy. The challenge is to boost supply and reduce 
demand. We need to choose wisely and we need to act soon. How we choose 
to meet the challenges and seize the opportunities will help determine 
our quality of life and economic prosperity in the future. 

We are currently studying the determinants of gasoline prices in 
particular, and the petroleum industry more generally, including an 
evaluation of world oil reserves; an assessment of the security of 
maritime facilities for handling and transporting petroleum, natural 
gas, and petroleum products; an analysis of the viability of the 
Strategic Petroleum Reserve; and an assessment of the impacts of a 
potential disruption of Venezuelan oil imports. With this body of work, 
we hope to continue to provide Congress and the American people the 
information needed to make informed decisions about energy that will 
have far-reaching effects on our economy and our way of life. 

Mr. Chairman, this completes my prepared statement. I would be happy to 
respond to any questions you or the other Members of the Committee may 
have at this time.

FOOTNOTES

[1] GAO, Motor Fuels: Understanding the Factors That Influence the 
Retail Price of Gasoline, GAO-05-525SP (Washington, D.C.: May 2, 2005). 

[2] The large percentage of total world gasoline production consumed by 
the United States, in part, reflects the fact that diesel is a commonly 
used fuel for cars in Europe, while automobiles in the United States 
primarily run on gasoline. If all motor vehicle fuels were accounted 
for, the United States' share of these fuels would be smaller than its 
share of gasoline. However, we do not have the data to present this 
more comprehensive measure. 

[3] The latter two categories, refining and distribution and marketing, 
includes costs associated with these activities as well as profits. The 
figure is a snapshot of how much each component contributes to the 
price of a gallon of gasoline, and how the relative proportions 
attributable to each component vary over time as crude oil prices and 
other factors change. 

[4] EIA uses tax data from the American Petroleum Institute (API) for 
its tax analysis. According to API, these data include applicable state 
sales taxes, gross receipts taxes, and other applicable fees but 
largely exclude local taxes, which may average about 2 cents per gallon 
nationwide.

[7] Higher oil prices, because they increase the U.S. trade deficit, 
may also contribute to the further devaluation of the dollar. Hence, 
analysts have called this process a vicious cycle in which a weak 
dollar drives up oil prices, which then feeds back into the trade 
deficit causing the dollar to weaken further.
