The United States has 4.5% of the world's population. According to world energy use figures, what share of the world's oil production does the U.S. consume per year, and what fraction of that oil is imported?
AIt consumes 24% of world oil production, with 66% imported
BIt consumes 4.5% of world oil production, with 10% imported
CIt consumes 50% of world oil production, with 90% imported
DIt consumes 24% of world oil production, entirely produced domestically
Answer & Solution
Correct answer: A. It consumes 24% of world oil production, with 66% imported
1. Even though the U.S. has only 4.5% of the world's population, it consumes a much larger share of world oil production, specifically 24% per year.
2. Of that 24% consumed, 66% of the oil used is imported rather than produced domestically.
3. The population share of 4.5% describes people, not oil consumption, so pairing 4.5% with oil use understates the actual figure.
4. The oil is not entirely domestic, since a clear majority, 66%, comes from imports, ruling out the option claiming none is imported.
