Episode #103

KQED World: Sun, Apr 12, 2015 -- 10:00 PM

In this episode, we focus on the electrification of the American economy - in transportation, shipping, airlines, even in the US military and its importance to our national security. Our host, Scientific American's David Biello, journeys across the country to examine America's switch to electrification as a key strategy in reducing our foreign oil dependence while achieving our economic, environmental and energy security goals. Our journey begins in Iraq where moving diesel fuel in order to generate electricity became that war's most dangerous occupation. From the Middle East David looks at the Pentagon's role in advancing energy technology. He'll then travel to one of the busiest ports in the world - the Port of Los Angeles, then onto Austin, Texas, to a neighborhood that boasts the highest concentration of electric vehicles in the country. Then it's off to Chicago, Washington, DC, and Berkeley, California all in the search for signs of a new energy future.
