The energy systems of the United States, Canada, and Mexico operate through two key bilateral connections rather than a fully integrated trilateral network. Canadian crude oil primarily flows south to fuel US refineries, while American natural gas moves southward to support Mexico's energy needs. This structure highlights how energy security in each country depends heavily on these specific cross-border exchanges rather than a unified continental system.
Data shows that Mexico obtains about 70% of its energy from the United States, while the US imports around 60% of its oil from Canada. These figures emphasize the critical nature of these bilateral relationships, which underpin the stability and performance of the North American energy market. Although the system is not fully integrated among all three nations simultaneously, these key energy corridors are vital for maintaining economic and industrial cohesion across the continent.
