I think that if the Green movement can hit on something big within the next few years - a new Inconvenient Truth, or some green messiah - then it's plausible that we'll finally see nations start to make major, real moves towards eco-friendly and renewable power sources. This would likely start in West Europe and ripple outwards, and would wean many countries from a dependence on the fossil fuels from the Middle East and Russia. If China, Russia and the Middle East all fall in together to create an economic triumvirate dependent on oil then this might lay the foundations for alliances in other sectors.

We would be looking at literal 'power blocs'.
