America experienced its first oil shock. Within days of the cutoff, oil prices rose from $2.90 to $11.65 a barrel; gasoline prices soared from 20 cents to $1.20 a gallon, an all-time high. Across America, fuel shortages forced factories to close early and airlines to cancel flights. Filling stations posted signs: ‘Sorry, No Gas Today.’ If a station did have gasoline, motorists lined up before sunrise to buy a few gallons; owners limited the amount sold to each customer. Motorists grew impatient. Fistfights broke out, and occasionally, gunfire. President Nixon called for America to end its dependence on foreign oil. ‘Let us set as our national goal. . . that by the end of this decade we will have developed the potential to meet our own energy needs without depending on any foreign energy source,’ he said. We have still not met this goal.
