The United States and China are the top largest consumers of oil in the world, totaling 19.1 million and 14.3 million barrels per day, respectively. In the last decade, the share of global oil consumption from Europe and North America have begun to decline, whereas consumption levels from Asia Pacific and other regions have risen. As other sources of energy become more cost effective and due to the prominence of new transportation technologies, oil consumption worldwide is expected to reach a peak in the near future.
Refining oil
Crude oil is refined into petroleum products, such as gasoline and diesel fuel, and used for a wide variety of products, although many refineries focus on transportation fuels. Generally, crude oil feedstocks are processed by an oil production plant and is an essential part of the downstream petroleum industry.
