Oil (or petroleum) is the most used energy resource in the world and provides more than 90% of global transportation energy.
About two-thirds of global oil use is for transportation.
Oil is a depletable, non-renewable mixture of liquid hydrocarbons burned to convert chemical energy into heat, and a leading contributor to air pollution and climate change.
Because most oil (54%) is produced by just five countries (the U.S., Saudi Arabia, Russia, Canada, and Iraq), securing access to this resource has significant geopolitical consequences.
