A social experiment is being conducted on an expanding scale across the world—it’s called Transition, often followed by the words Town, Initiative, Network, or Movement. Transition brings neighbors together to “power down” in response to peak oil, climate change, and economic hardships; it promotes community empowerment and the promise of a better life for all. Terra Verde talks with Alexa Hauser of Albany, Beverly Pitzer of San Francisco, and Susan Silber of Berkeley about the origins, objectives, and outcomes of Transition.
