The World in 2050: Global Innovation and Energy?

In this Keynote Conversation from the WorldAffairs 2012 conference, we
examine how innovation will help us find solutions to the energy
challenges we face today and expect to face going forward to 2050.  Our
energy needs are still rising in the US and are rising much faster in
many parts of the world. Many forecasters predict that global energy
demands will rise by 40% between now and 2050. Looking forward, it seems
clear that we will continue to rely heavily on conventional resources
such as oil, coal, natural gas, and nuclear energy. But, will innovation
and breakthroughs in technology allow us to capture significant amounts
of affordable energy from other sources with important environmental
benefits, and allow us to become much more efficient in our use of
energy globally?
