According to ExxonMobil’s new energy forecast, “The Outlook for Energy: A View to 2040”, global energy demand in 2040 will be about 30% higher than it was in 2010. The increase is being led by economic growth in developing countries. The report predicts that energy demand will shift toward less carbon-intensive energy sources such as natural gas, though oil will remain the most widely used fuel. The expanded use of hybrid vehicles will push the average new car fuel economy to nearly 50 mpg by 2040. The forecast also identifies rising electricity demand as the biggest influence on energy trends. Global demand for electricity is projected to rise 80% as developing economies and living standards improve. The fuel used to produce electricity is likely to change dramatically. Up to 30% of the world’s electricity production could be facilitated by natural gas, while coal will begin its first long-term decline in modern history, according to the report.
