NPR: Visualizing The Grid

NPR has recently added a very powerful visualization tool to their web site. It allows a visitor to display on a map the electrical grid and it's sources of power, as well as current solar and wind infrastructure.

The U.S. electric grid is a complex network of independently owned and operated power plants and transmission lines. Aging infrastructure, combined with a rise in domestic electricity consumption, has forced experts to critically examine the status and health of the nation's electrical systems.
