The Solar Decathlon is an event sponsored by the U.S. Department of Energy, in which students from around the world design, build and operate solar-powered and energy-efficient houses. The team with the house that best incorporates elements such as design excellence, affordability, customer appeal and maximum energy efficiency, wins the competition. The event is meant to educate both the public and the students involved in the project of energy and energy efficiency. The first day of the Solar Decathlon was rainy, which did not deter the visitors as they waited in line to visit each house and discover what made it so special. Fortunately, the rain did not dampen the spirits of the crowds and was no deterrent to this solar event.
