  15. 15. “If we don’t change direction soon, we’ll end up where we’re heading” There are few signs that the urgently needed change in direction in global energy trends is underway. Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushingRonald Wennersten/Industrial Ecology/KTH to a new high.
