The terms transition town, transition initiative and transition model refer to grassroot community projects that aim to increase self-sufficiency to reduce the potential effects of peak oil, climate destruction, and economic instabilitythrough renewed localization strategies, especially around food production and energy usage. In 2006, the founding of Transition Town Totnes in the United Kingdom became an inspiration for other groups to form. The Transition Network charity was founded in early 2007, to support these projects. A number of the groups are officially registered with the Transition Network. Transition initiatives have been started in locations around the world, with many located in the United Kingdom and others in Europe, North America and Australia. While the aims remain the same, Transition initiatives' solutions are specific depending on the characteristics of the local area.
The term, "transition town" was coined by Louise Rooney and Catherine Dunne.
The transition model can be applied to different types of places where people live, such as villages, regions, islands and towns. The generic term is "transition initiative", which includes transition neighborhoods, communities, and cities, although "transition town" is in common usage.
In 2004, permaculture designer Rob Hopkins set his students at Kinsale Further Education College the task of applying permaculture principles to the concept of peak oil. The output of this student project was the ‘Kinsale Energy Descent Action Plan'.
This looked at across-the-board creative adaptations in the realms of energy production, health, education, economy and agriculture as a "road map" to a sustainable future for the town. Two of his students, Louise Rooney and Catherine Dunne, developed the Transition towns concept. They then presented their ideas to Kinsale Town Council, to which the councilors decided to adopt the plan and work towards energy independence.
Hopkins moved to his hometown of Totnes, England, where he and Naresh Giangrande developed these concepts into the transition model.
