A year ago peak oil author Dave Cohen christened 2009 “A Year We Will Live To Regret.” But as it happens, 2010 has brought its own mother lode of discouragement, failure and tragedy. It began on the heels of the bungled climate change summit in Copenhagen, a major blackout in southern France and news of a disastrous crash in Yemen’s oil revenues. Before the year had rounded its halfway mark, it had presided over the Deepwater Horizon oil spill, the worst environmental disaster in U.S. history. And as if all this weren’t enough, 2010 also saw the sudden and unexpected death of one of the very icons of the peak oil movement, the revered Matthew R. Simmons.
