Most protagonists of sustainable development ignore modern insights in the nature of technology, which has led to an emphasis on technological solutions. The notable exception is transition management. However, both social construction of technology and transition management have been criticized as ignoring distributions of power in society, and for not offering guidance in the choice of the most sustainable technologies. The reviewer criticizes this approach: the issue is not to choose the right technologies, but to address the root causes of unsustainability in society. In addition to politization of transition management the reviewer argues that strong visions are necessary to lead the way. Technologies could help to develop those visions.
