The book investigates two important subjects simultaneously. On the one hand, it is concerned with the detailed processes which have lead to quite different innovation diffusion pathways of combined heat and power technology in the UK and Germany since the early Eighties. On the other hand, this empirical work serves to demonstrate the application of a novel multi-disciplinary and prospective research approach. This approach, which is explicitly formulated in both theoretical and methodological terms, is used to explore the possibilities and limitations of controlling the transformation of large socio-technical systems by poltical means.

Two general questions stood at the beginning of this PhD-thesis, namely: • What are the mechanisms which lead to the emergence and establishment of new technologies? • How can this process of technological change be influenced politically? In this sense, conceptual and theoretical interests were the early driving forces of the research work. This is also reflected in the considerable attention paid to the nature of technological change and political control. The result is an holistic per spective which builds on inputs from different disciplines and aims at dynamic interpretation. This, however, created a severe methodological problem: How could such a comprehensive perspective be used constructively? To develop this link between theory and forward-looking, policy-oriented analysis, and to devise a methodology which showed explicitly how this approach could be used in a con structive way were in fact the major challenges of this research project. The appli cation to the example of combined heat and power generation, and the comparison of the developments in the UK and in Germany serve the purpose to demonstrate how this approach and methodology can be implemented in practice. These as pects were also of particular interest to the Institute for Prospective Technological Studies (IPTS), one ofthe institutes of the European Commission's Joint Research Centre, where most of the research work reported in this PhD-thesis was carried out.

Klappentext

Two general questions stood at the beginning of this PhD-thesis, namely: What are the mechanisms which lead to the emergence and establishment of new technologies? How can this process of technological change be influenced politically? In this sense, conceptual and theoretical interests were the early driving forces of the research work. This is also reflected in the considerable attention paid to the nature of technological change and political control. The result is an holistic per­ spective which builds on inputs from different disciplines and aims at dynamic interpretation. This, however, created a severe methodological problem: How could such a comprehensive perspective be used constructively? To develop this link between theory and forward-looking, policy-oriented analysis, and to devise a methodology which showed explicitly how this approach could be used in a con­ structive way were in fact the major challenges of this research project. The appli­ cation to the example of combined heat and power generation, and the comparison of the developments in the UK and in Germany serve the purpose to demonstrate how this approach and methodology can be implemented in practice. These as­ pects were also of particular interest to the Institute for Prospective Technological Studies (IPTS), one ofthe institutes of the European Commission's Joint Research Centre, where most of the research work reported in this PhD-thesis was carried out.
