Grand challenges in energy
The document discusses grand challenges in energy and perspectives on moving towards more sustainable systems. It notes that while global energy demand and CO2 emissions rebounded in 2010 after the economic downturn, urgent changes are still needed. It explores perspectives on changing direction, including overcoming barriers like technologies, economies, management, and mindsets. The document advocates a systems approach and backcasting from desirable futures to identify pathways for transitioning between states.

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, pushing Ronald Wennersten/Industrial Ecology/KTH to a new high.
