This issue brief compares projected savings from drilling in presently restricted offshore zones, savings under the Energy Independence and Security Act of 2007, and the projected savings from the fuel efficiency schedule proposed by Senator Obama. The issue brief projects savings through 2027, the year in which offshore drilling would reach peak capacity.

Oil Drilling and Automobile Fuel Economy: 
The Relative Impact on Oil Prices  
 
BY MATTHEW SHERMAN AND DEAN BAKER* 
 
Today, the Republican Study Committee put forth an alternative to the Federal Reserve’s bailout plan 
that includes a provision to open the Artic National Wildlife Refuge (ANWR) to oil drilling. This comes 
just a week after the U.S. House of Representatives passed a bill that lifted some restrictions on oil 
drilling  in  America's  outer  continental  shelf.  The  bill  was  supported  by  many  Democrats  but  was 
criticized by many Republicans for not going far enough and for not opening up enough areas to 
drilling. And in supporting the lifting of all restrictions on drilling in the outer continental shelf, Senator 
John  McCain  argues  that  increased  offshore  production  will  reduce  dependence  on  foreign  oil,  in 
addition to lowering gas prices.  
 
However,  the  Energy  Information  Administration  (EIA)  has  concluded  that  even  proposals  for 
comprehensive offshore drilling will have no impact in the near-term, since it will be close to a decade 
before  any  oil  can  be  extracted  from  the  coastal  areas  in  question.  The  EIA  estimates that actual 
production would not begin until 2017 and would not reach peak production until 2030. The EIA 
projects domestic oil production to increase by 200,000 barrels a day (0.2 percent of projected world 
production), an amount too small to have any significant effect on oil prices.1  
 
It is interesting to compare the potential impact on oil prices of the proposal to remove restrictions on 
offshore  drilling  and  in  ANWR  with  the  impact  of  the  recently  passed  Energy  Independence  and 
Security Act of 2007. This legislation included regulations designed to increase production of renewable 
fuels and increase energy efficiency. Most significantly, the measure raised the corporate average fuel 
economy (CAFE) standard for automobiles. Under the legislation, the minimum CAFE standard for 
passenger vehicles must average at least 35 miles per gallon (mpg) by 2020, up from the previous 
minimum standard of approximately 27.5 mpg at present.2  
CAFE standards were first implemented in 1975 at 20 mpg and increased to 27.5 mpg in 1985. The 
CAFE program had the direct effect of reducing national oil consumption by compelling automakers to 
produce  more  fuel-efficient  cars.  The  Board  on  Energy  and  Environmental Systems estimates that 
without CAFE standards, gasoline consumption (and crude oil imports) would be about 2.8 million 
barrels a day greater.3  Currently, our consumption of oil is estimated at 20.8 million barrels a day.4

Figure 1 shows the relative impact on oil production of lifting drilling restrictions in ANWR and on the Outer 
Continental  Shelf,  compared  with  the  impact  on  oil  consumption  of  increasing  standards  of  automobile  fuel 
efficiency.  
 
The  Energy  Independence  and  Security  Act  of  2007  should  have  a  similar  impact  on  fuel  efficiency  and  oil 
consumption, also lowering consumption by approximately 2.8 million barrels per day by 2027, the year when the 
EIA projects that peak production could be reached from drilling in the currently protected offshore area.5  If this is 
the case, then the increase in fuel economy standards contained in the recent legislation will decrease oil dependency 
by an amount fourteen times greater than any comprehensive offshore drilling effort.  
 
Senator Obama has proposed a slightly more ambitious fuel efficiency schedule which would increase mileage 
standards at the rate of 4 percent a year. This would lead to somewhat greater energy savings, especially if the 
increases are continued beyond the 2020 date. In this case, the mileage standard will reach 52 miles per gallon by 
2027, which will raise the average for all cars driven to just less than 42 miles per gallon by that date. In this case, the 
savings in oil consumption would be equal to 4.2 million barrels a day by 2027.6 This amount would be 21 times as 
large as the impact of opening up the protected offshore areas to drilling.

5 This calculation assumes that the efficiency of the fleet of cars sold increases at the rate of 0.85 MPG per year between now 
and 2020. It also assumes that each year a car is on the road it is driven 10 percent less (e.g. 2005 cars are driven 10 percent less 
than 2006 cars) and that it is pulled off the road altogether after 20 years. It also assumes a baseline where gasoline consumption 
rises by 10 percent from 9 million barrels per day in 2008 to 10 million barrels per day in 2027.   
6 This calculation makes the same assumption about the rate at which cars are pulled off the road.  Offshore Drilling and Automobile Fuel Economy •3 
 
In response to the $700bn bailout proposed by the Federal Reserve, a recent Republican legislative proposal 
supports lifting the restrictions on drilling. The EIA has estimated that drilling in the Arctic National Wildlife 
Refuge would have no effect in the near-term. Production would not begin until 2018, and in 2030, production 
would plateau at 710,000 barrels a day. This amount of oil is projected to decrease the price of oil by about $2.00 a 
barrel, which would bring down the price of gasoline by less than 5 cents a gallon.7 
 
In conclusion, the increase in CAFE standards signed into law by President Bush will have four times the impact on 
oil dependency as drilling in the Arctic National Wildlife Refuge and fourteen times the impact as drilling in the 
Outer Continental Shelf.  Senator Obama’s conservation proposal would have 21 times the impact of opening up 
drilling in protected offshore areas and 6 times the impact of drilling in the Arctic National Wildlife Refuge. The 
impact of opening drilling in either area will be zero for close to a decade. Even when these regions attain peak 
production in close to twenty years, the potential impact on gasoline prices will still be negligible.
