On Friday at 10 a.m., the U.S. Department of Energy Solar Decathlon  opens in West Potomac Park  in Washington D.C. The event provides a one-of-a-kind opportunity for members of the public to tour homes that save energy and money—and are powered by the sun. Many of my colleagues describe attending Solar Decathlon as one of the highlights of their professional careers, and I’m hopeful I’ll be able to squeeze in a visit during a quick work trip to D.C. later this week.
The Solar Decathlon is a collegiate competition where teams  design and build energy-efficient houses powered by the sun. These teams spend almost two years creating houses to compete in the 10 contests of the Solar Decathlon. The event challenges collegiate teams to design, build, and operate solar-powered houses that are cost-effective, energy-efficient, and attractive. The winner of the competition is the team that best blends affordability, consumer appeal, and design excellence with optimal energy production and maximum efficiency.
The Solar Decathlon website  is filled with all kinds of information highlighting the event and the student teams who participate. Some of my favorite sections include:
- Photos of the day 
- Videos 
- News blog 
- Solar Decathlon Facebook page 
- Team videos on YouTube 
- Foursquare  check in
- Where are the houses now ?
While you can learn a lot about the Solar Decathlon on the Web, I hope if you’re in the D.C. area Sept. 23-Oct. 2  you’ll have a chance to check it out in person—and be one of the thousands of people who claim each decathlon is an inspiring and educational experience.
