Discussions about “peak oil” long ago shifted from when crude oil supply might reach its apex to when oil demand will peak and start to decline as the world becomes ever more energy-efficient and shifts to lower-carbon sources of energy. The date at which oil demand will stop growing is highly uncertain, and small changes in assumptions can lead to vastly different estimates. Also, there is little reason to believe that once oil demand peaks it will fall sharply — the world is likely to demand large quantities of oil for many decades to come. More importantly, the shift in paradigm from an age of perceived oil scarcity to an age of oil abundance poses major challenges for oil-producing countries as they try both to ensure that their oil is produced and consumed, and at the same time diversify their economies to prepare for a time when they can no longer rely on oil to provide their main source of revenue. Today, the Oxford Institute for Energy Studies and BP Group Chief Economist Spencer Dale summarize their recent report on future trends in oil supply, demand and prices.
