Shades of some of the Science Fiction topics the authors used to write about. Energy Wars. Society is hooked on cheap energy, obviously it won't stay cheap, and as the third world discovers a need for more the price will soar to unbelievable levels. The nation or group of nations that are first on the bandwagon to implement renewable sources will have a long term advantage. Reactors, hydrogen fuel cells, biodesel, Ethanol, wind and wave tapped sources will all have to be explored along with geo-thermal possibilities. Mammoth Mountain and St Helens, to mention a couple, sit on pools of molten magma. Pump in water harvest steam. Sounds easy, obviously not.
