This month the U.S. Department of Energy is sponsoring The Solar Decathlon. The event joins 20 college and university teams in a competition to design, build, and operate the most attractive and energy-efficient solar-powered house.  Following is a video overview of the event.  You can also find more information at www.solardecathlon.org.  If you’re in the DC area, head on down to the National Mall sometime in the next couple weeks to see the projects in person.  If you aren’t in the DC area, you can view all the projects online at The Solar Decathlon website.
