A survey by the U.S. Energy Information
Administration shows that retail gasoline prices across the United States have
increased for 11 consecutive weeks, with the largest increase in the Midwest
and the highest average gas prices in the West Coast. The oil price increase is
expected to be mainly caused by reduced productivity at refineries due to power
shortages.
According to comprehensive foreign reports
on April 9, the U.S. Energy Information Administration (EIA) said that in the
week ending April 9, the average retail price of gasoline in the United States
rose by 9.5 cents to $2.802 per gallon.
EIA said that gasoline retail prices have
increased for 11 consecutive weeks, an increase of 11.9 cents compared with the
same period in 2006.
This time, oil prices rose across the
country, with the largest increase in the Midwest, rising 13 cents to $2.744
per gallon. The reason for this price increase is due to reduced productivity
at large refineries in various regions due to power shortages.
The West Coast region had the smallest
increase, with an average regional increase of 4.2 cents per gallon, but the
region still had the highest average gas price, reaching $3.138 per gallon. Oil
prices on the West Coast have remained above $3 for three consecutive weeks.
High oil prices in California are caused by
extremely low refinery productivity, high maintenance costs and unexpected
expenses.
EIA made the above gasoline price survey
results after conducting a telephone sample survey of approximately 900 gas
stations.
