The 2008 bestselling The Transition Handbook suggested a model for a community-led response to peak oil and climate change. Since then, the Transition idea has gone viral across the globe. The Transition Companion picks up the story today. It shows how communities are working for a future where local enterprises are valued and nurtured; where lower energy use is seen as a benefit; and where co-operation, creativity and the building of resilience are the cornerstones of a new economy.
