Updated each year, the Outlook analyzes the trends that will shape global energy supply and demand over the coming decades. This year's report reveals a number of key findings about how we use energy, how much we will need in the future and what types of fuels will meet demand. Key findings of this year's Outlook include: Efficiency will continue to play a key role in solving our energy challenges; Energy demand in developing nations (Non OECD) will rise 65 percent by 2040 compared to 2010, reflecting growing prosperity and expanding economies; With this growth comes a greater demand for electricity; Growth in transportation sector demand will be led by expanding commercial activity as our economies grow; Technology is enabling the safe development of once hard-to-produce energy resources, significantly expanding available supplies to meet the world’s changing energy needs. Oil will remain the No. 1 global fuel, while natural gas will overtake coal for the No. 2 spot ; and Evolving demand and supply patterns will open the door for increased global trade opportunities.
