More than a century after Edison invented a reliable light bulb, the nation's electricity distribution system, an aging spider web of power lines, is poised to move into the digital age.
The "smart grid" has become the buzz of the electric power industry, at the White House and among members of Congress. President Barack Obama says it's essential to boost development of wind and solar power, get people to use less energy and to tackle climate change.
