'Frank Geels's book gives us a new perspective on how society moves from one technological regime to another. Understanding these transitions is essential if we are to get to grips with what we need to do to switch our societies to more sustainable states and how technologies figure in that switch.' - Ken Green, Institute of Innovation Research, The University of Manchester, UK This important book addresses how long term and large scale shifts from one socio-technical system to another come about, using insights from evolutionary economics, sociology of technology and innovation studies. These major changes involve not just technological changes, but also changes in markets, regulation, culture, industrial networks and infrastructure. © Frank W. Geels 2005. All rights reserved.
