President Barack Obama said today the United States must reduce its dependence on oil. And even he acknowledged this is not a new idea. OBAMA-ENERGY

“Richard Nixon talked about freeing ourselves from dependence on foreign oil. And every president since that time has talked about freeing ourselves from dependence on foreign oil,” he said at Georgetown University.

“Politicians of every stripe have promised energy independence, but that promise has so far gone unmet,” Obama said.

As all of those presidents found, it is no small task to wean the world’s largest oil consumer and importer away from that addiction — especially since U.S. domestic oil production peaked in the early 1970s.

So why will this time be any different?

Obama has set a goal that he says is “reasonable,” “achievable,” and “necessary,” of reducing oil imports by one-third over a decade.
