Increased. In 1950, 8.4% of the total volume of crude oil consumption in the United States was imported. Imports as a percentage of the total consumption peaked at 66.6% in 2006, and have declined since to 56.9% in 2012. Note that in my calculations using the U.S. Energy Information Administration raw data, Consumption = Production - Exports + Net Imports. See also the related link for the EIA generated graph. Imports of coal, natural gas, and other forms of energy into the U.S. are considered negligable during this time period.
