ExxonMobil issued its Outlook for Energy this week, predicting that global energy demand would rise 35 percent from 2010 to 2040 due to steady growth in countries now lacking electricity, appliances, and transport. “People want a warm home, a refrigerator, a TV, someday a car, and a cellphone,” William Colton, ExxonMobil’s vice president for corporate strategic planning, told the Associated Press. That means dramatic growth, but there’s more, buried in the fine print of the ExxonMobil press release: “Without gains in efficiency, global energy demand could have risen by more than 100 percent.” In other words, it will take huge growth in advanced energy technologies to keep the increase in energy consumption down to 35 percent by 2040. That makes the advanced energy opportunity even greater.
