On the National Mall

The public gets a first look at the solar-powered houses as the U.S. Department of Energy Solar Decathlon opens to the public on the National Mall in Washington, D.C.
The Solar Decathlon is a worldwide competition in which 20 colleges and universities are chosen to design, build and operate the most attractive and energy-efficient solar-powered home.
