Predominantly a nuclear energy producer, France has very few natural energy resources, and its energy sector is primarily focused on electricity generation. However, France is a major importer of oil, which accounted for 65% of total net imports in 2004, from such key fossil-fuel suppliers as Saudi Arabia and the Russian Federation.

Headquartered in Paris, Total S.A. is the fifth largest publicly traded oil and gas company in the world and is a significant international offshore player.
