Quizplus · Accepted Answer

Per capita energy use in the U.S. increased sharply from 1950 to the 1970s but has since declined, as a result of improvements in energy efficiency and adoption of renewable energy sources. Energy intensity, or the amount of energy required to produce a unit of GDP, has also been declining since the 1970s due to similar factors.
