The Energy Wars Heat Up: Six Recent Clashes and Conflicts on a Planet Heading Into Energy Overdrive

Conflict and intrigue over valuable energy supplies have been features of the international landscape for a long time. Major wars over oil have been fought every decade or so since World War I, and smaller engagements have erupted every few years; a flare-up or two in 2012, then, would be part of the normal scheme of things.

Instead, what we are now seeing is a whole cluster of oil-related clashes stretching across the globe, involving a dozen or so countries, with more popping up all the time. Consider these flash-points as signals that we are entering an era of intensified conflict over energy.

From the Atlantic to the Pacific, Argentina to the Philippines, here are the six areas of conflict -- all tied to energy supplies -- that have made news in just the first few months of 2012:

Fighting has since erupted all along the contested border between the two countries, accompanied by air strikes on towns in South Sudan. Although the fighting has not yet reached the level of a full-scale war, international efforts to negotiate a cease-fire and a peaceful resolution to the dispute have yet to meet with success.
