The Organization of Petroleum Exporting Countries said it expects demand for its crude oil to fall to 29.2 million barrels a day in 2018 from 30.3 million barrels a year this year. OPEC said rising supplies from other sources, such as Canadian oil sands, crude from Latin America and the increased use of biofuels would contribute to the fall in demand for its own output.
"This year's (report) demonstrates again that there is no shortage of oil and resources are plentiful," OPEC Secretary General Abdullah Al-Badry said in the group's 2013 World Oil Outlook report.
OPEC also predicted that global oil demand would rise from 81.2 million barrels a day in 2013 to 89.7 million barrels a day in 2020 and 100.2 million barrels a day in 2035. At the same time, renewables and other fuels will cut into oil's share of global energy use, from 32.2 percent in 2010 to 26.3 percent in 2035.
