Rob Hopkins, founder of the Transition concept, has written an excellent book describing the principles and practice behind Transition. The subtitle is "from oil dependency to local resilience" and is a reflection of the process that communities must go through to move towards a low fossil fuel future.
The book is divided in to three sections, 'The Head', 'The Heart' and 'The Hands', which describes the three elements of the personal transition. Essentially this is about understanding the problems, caring for the problems and doing something about it.
It's an inspiring book and is a good read. It's available here, but below is Rob describing the book in this short video:
