Beyond the Light Switch - Part III
Special | 56m 46s
On this edition of Beyond the Light Switch, we focus on the electrification of the American economy - in transportation, shipping, airlines, even in the U.S. 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.
