As of 2011, approximately 89 million barrels of oil and liquid fuels were consumed per day worldwide. That works out to nearly 32 billion barrels a year.
Where is the bulk of oil demand growth going to come from?
In the next five years, almost half of global oil demand growth will come from China according to the IEA, and this trend is set to continue to 2035 as oil demand from the transportation sector is growing strongly in countries such as China and India. In contrast, oil demand among OECD countries is expected to decline over the next two decades, driven mostly by government policies on fuel efficiency and the fact that rates of vehicle ownership are already high.
