How has the U.S. oil consumption generally changed over time?

C - Oil consumption has increased over time.

Historically, U.S. oil consumption has experienced significant growth, particularly during the 20th century with the rise of the automobile industry and suburban development. While there have been fluctuations due to economic conditions, fuel prices, and energy policies, overall oil consumption has generally trended upward, especially until around the mid-2000s. Since then, there have been periods of decline or stabilization, influenced by factors such as increased fuel efficiency, the rise of alternative energy sources, and changes in transportation patterns. However, overall, the long-term trend has been an increase in oil consumption, particularly in the context of the industrial and transportation sectors.
