What can a 9-year-old teach us about sustainability? Ask Carrick McCullough's dad, Colin from Our Renewable Nation, whose family values include teaching sustainability. Colin, his wife and their two boys traveled cross country in a veggie powered Beetle visiting renewable energy sites and sustainable companies to create a series of eco-videos for kids.

Their latest video is from the Solar Decathlon—a contest of universities across the globe to build zero energy homes and buildings, where Carrick shows off the latest in renewable energy technology, solar power and sustainable building. It’s quite incredible what types of innovation is taking place around green building.

They published their first video with 9-year-old Carrick interviewing Jeff Cresswell, the owner of Klean Kanteen, in Chico, CA that makes eco-friendly stainless steel water bottles a few weeks ago. Jeff talked to Carrick about the benefits of using stainless steel water bottles in regard to sustainability.

Carrick is quite an incredible 9-year-old kid and Change Agent who understands the impact of his actions and the world's behavior. He's using his language and interests to help share eco-friendly information with kids across the country. In the past, Carrick's created an award winning film seen by more than 200,000. They hope to distribute the videos to schools to help empower the youth to create a sustainable and renewable future.

He truly embodies the meaning of being a Change Agent--he's an independent spirit working toward making positive change in this world. Changents is helping Carrick tell his story and share his videos with people around the globe. He's growing awareness and raising support of his projects.

Last December, I spent three weeks in Japan. As a first-time visitor to the country, I spent most of my time just taking it all in…the people, the food, the cities, the country side, the social norms, and the practices relating to environmental action. Here were some of my observations:

The Japanese-made car is one of the most respected in the world and clearly, they love them here too. But more notably, people embrace bicycles, the Shinkansen (the bullet train goes up to 300 km/hour), and super wide-spread and efficient transit systems. As a foreigner, it was simple enough for me to get around, starting from the airport, and including the busy cities of Tokyo, Osaka, Kyoto and the countryside.
