On April 20, 2010, a blast aboard the Deepwater Horizon offshore oil platform killed 11 workers, critically injured others and caused a leak that spilled thousands of barrels of oil into the Gulf of Mexico for more than three months. The Deepwater Horizon, one of worst environmental disasters in history, is now the subject of a pulse-pounding new movie. Historian and archaeologist, USU Professor of Environment and Society, Joseph Tainter will watch the film with special interest. He is author, with Tadeusz “Tad” Patzek of University of Texas-Austin, of “Drilling Down: The Gulf Oil Debacle and Our Energy Dilemma.” Tainter, also author of the influential book “The Collapse of Complex Societies,” says “It takes energy to find and produce energy and the world’s remaining, untapped petroleum reserves are in deep, dark, cold, remote and dangerous locations...Energy is becoming very costly in terms of resources, safety and environmental health.”
