A map of world oil consumption in barrels a day per capita, 2007. Daily oil consumption by region from 1980 to 2006. This is a list of countries by oil consumption. The total worldwide oil consumption was 93 million barrels per day (bbl/day) on average in 2015 according to the International Energy Agency (IEA). Petroleum is used mostly, by volume, for refining into fuel oil and gasoline, both important "primary energy" sources. 84 percent by volume of the hydrocarbons present in petroleum is converted into energy-rich fuels (petroleum-based fuels), including gasoline, diesel, jet, heating, and other fuel oils, and liquefied petroleum gas.
