Test your Energy IQ to answer this question and others, and watch the video below to see how other people answered this question.

To the surprise of many, it turns out that our friendly neighbor to the north, Canada, is the largest U.S. supplier of imported crude oil, but more than half of the survey respondents believed that Saudi Arabia was our largest supplier.
