U.S. supermajor Exxon Mobil said it expected global energy demand will increase 30 percent by 2040 though the world economy should double in size during that period.
Exxon Chief Executive Officer Rex Tillerson told the World Petroleum Congress in Qatar that growing demand was a good sign because it indicated a general trend in economic recovery.
Global energy demand contracted during the recession that started globally around 2008. Tillerson said economic recovery meant the standard of living would increase, notably in the developing world.
To meet surging demand, he said, businesses need a policy climate that encourages sound investment, global cooperation and advanced innovation. Public citizens, he said, should understand the importance of responsible energy development while governments have an obligation to create a stable regulatory framework.
"History proves that energy policies that are efficient and market-based are the best path to economic growth and technological progress," he said.
