I predict that "Energy Security" is going to be one of the big political and media catch-phrases over the next decade. It's inevitable as the oil supply can no longer meet market demands and energy prices keep rising. It will become paramount for each country to establish stable sources in order to protect its economy.
You could argue that the US occupation of Iraq is a move to ensure energy security. Chinese corporations are beginning to buy foreign energy companies. The UK is edging towards a pro-nuclear policy. Dirty fuels are back on the table as an option. And no where will be off-limits when it comes to searching for the last patches of oil.
Be ready for some nasty politics as competition between nations increases. And in a world based on globalisation, if you don't have energy security, you don't have food security either.
