US historical oil imports

Frome the US EIA:


Compare that to this chart:


How do you square a spike in imports occurring roughly at the same time as the OPEC embargo?

There is this:

"The rapid increase in crude prices from 1973 to 1981 would have been much less were it not for United States energy policy during the post Embargo period. The US imposed price controls on domestically produced oil in an attempt to lessen the impact of the 1973-74 price increase. The obvious result of the price controls was that U.S. consumers of crude oil paid about 50 percent more for imports than domestic production and U.S producers received less than world market price. In effect, the domestic petroleum industry was subsidizing the U.s. consumer."

That would represent a strong negative incentive to domestic production and exploration. Truly a colossal policy blunder. From the same source:

"In the absence of price controls U.S. exploration and production would certainly have been significantly greater. Higher petroleum prices faced by consumers would have resulted in lower rates of consumption: automobiles would have had higher miles per gallon sooner, homes and commercial buildings would have been better insulated and improvements in industrial energy efficiency would have been greater than they were during this period. As a consequence, the United States would have been less dependent on imports in 1979-1980 and the price increase in response to Iranian and Iraqi supply interruptions would have been significantly less."

Exactly.
