Solar Decathlon

LLOYD: 
Usually that definition includes the word "athletic," but the 2007 Solar Decathlon in the nation's capital, is more about mind power. Here's what we mean: Ten contests, 20 college teams, One goal: To create the best, most energy-efficient, sunlight-powered home possible. Gary Nurenberg describes how their ideas today, could shape the house you live in tomorrow.

GARY NURENBERG, CNN REPORTER: 
The International Solar Decathlon on Washington's National Mall is a design competition among 20 college teams. Those are solar panels on the roof of a house designed by students from Madrid. Inside, they built this wall from discarded almond shells. The University of Maryland team has linked its solar house to the Web.

JOHN KUCIA, UNIVERSITY OF MARYLAND: 
If you forget and leave the closet light on and you're at work, you just log on and turn it off from there.

NURENBERG: 
Designers at Texas A & M used solar hot water tubes on the patio.

JOHN CANEZ, TEXAS A&M: 
We put them vertical to create a privacy wall to create this nice space on the west side and it also protects this nice glass visage that we have.

NURENBERG: 
The University of Colorado at Boulder is basing its design on a converted shipping container, which contains all the key mechanical elements of the house.

CHAD CORBIN, UNIVERSITY OF COLORADO, BOULDER: 
So that we can ship that to a site and have that be the living system of the building. The user can then customize the building anyway they like.

NURENBERG: 
It's a long way from a design class in a sterile classroom.

NURENBERG: 
The houses are judged on innovation and on livability, one reason the competition was created.

SOT: 
The cost of solar products were coming down, but we didn't know how to integrate them or get them designed aesthetically into buildings.

NURENBERG: 
The houses costs between 500,000 and a million dollars, and drew big crowds over the weekend. But solar is attracting more than just gawkers.

SECRETARY OF ENERGY: 
It is the first time that I have seen the venture capitalists of the United States putting big money into energy projects. They're putting big money into solar energy...

NURENBERG: 
Solar currently contributes to less than one percent of America's energy supply. With rising oil prices, competitors here are convinced that is about to change. Gary Nurenberg, CNN, Washington.

Shoutout

AZUZ: 
Time for the Shoutout! Which of these is a renewable resource? If you think you know it, shout it out! Is it: A) Natural gas, B) Coal, C) Minerals or D) Wind? You've got three seconds -- GO! Natural gas, coal and minerals can be used up so much faster than they're consumed, so they're considered nonrenewable. Wind, on the other hand, is renewable. That's your answer and that's your Shoutout!
