Which country exports the most oil to the United States?

• A. Saudi Arabia
• B. Venezuela
• C. Canada
• D. Mexico

Answer: (B)

Understanding energy trade patterns and infrastructure helps explain which country exports the most oil to the United States. Canada has long been the top source of crude oil imports for the U.S. because of their proximity and the large production from Alberta's oil sands. A vast network of pipelines moves crude from western Canada to U.S. refineries that are built to process this heavy crude, keeping transportation costs low and supply reliable. While Saudi Arabia remains a major supplier and can supply large volumes, Canada typically provides more crude oil to the United States on a yearly basis. Venezuela’s exports have declined due to sanctions and production issues, so they contribute far less. Mexico also exports oil to the United States, but not at the scale of Canada.
