The quest for energy security

It's hard to imagine a world in which hydrocarbons DON'T play a central role in global economics. The attack on the gas installation in Algeria is a reminder of the risks we take to secure our energy sources. Manuela Saragosa and guests discuss the quest to make energy production safer and more efficient. And where will future energy supplies come from. BP's chief economist Christof Ruhl, chief energy analyst at Ecobank Rolake Akinkugbe and Malcolm Grimston, Associate Fellow: Energy, Environment and Resources at Chatham House look at how the world will satisfy growing energy demands in future. And comedian Colm O Regan looks at his own personal energy consumption habits and muses on why it's not easy being green.
