World Oil Energy Consumption by Sector, 1973-2013
Oil can be put to a variety of uses, with transportation accounting for a growing share of the oil consumed around the world. While the transport sector consumed 42% of the oil in in 1973 this share climbed to 63.8% in 2013. The growing level of motorization is a core component behind this relative growth, including the growth of international trade and the use of bunker fuel by maritime shipping. Non-energy uses mostly relate to the petrochemical industry where petroleum is used to manufacture products such as plastics or fertilizers. Other sectors concern agriculture (powering farm equipment), commercial and public services (power generation) and residential (heating oil).
