The electricity systems of many countries are currently undergoing a process of transformation. Market liberalization has induced major mergers and acquisitions in the electricity sector, but has also forced companies to seek out new business areas. Environmental regulations, like the Kyoto process and the European Emissions Trading Scheme, are exposing the sector to external pressure. New technologies – such as renewable energy, combined heat and power (CHP), or “clean coal” technologies – are emerging. Recent worldwide experiences with blackouts have once more put security of supply on the agenda. In Germany, the nuclear phase-out and decommissioning of outdated coal plants will lead to a need for replacement of more than one third of the current generation capacity by 2020. The need for replacement is an extremely important driving force for the current transformation, forcing conventional and new technologies to compete for a role in the future energy supply. The overall transformation of electricity systems is neither driven nor shaped by technical or societal modifications alone, but rather by a rich diversity of processes in the realms of technology, politics, society and economy.

The introduction of micro CHP -- the simultaneous production of heat and power in a single building based on small energy conversion units such as Stirling and reciprocating engines or fuel cells -- is of increasing political and public interest. This book introduces into micro CHP systems and technologies, and presents the results of the first such investigation carried out by four German research bodies.

Innovation is key to achieving a sustainable electricity system. New technologies and organizational changes can bring about more sustainable, climate-friendly electricity structures. Yet the dynamics of innovation are complex, and difficult to shape. This book, written by experts in the field, sets out to explore the dynamics, the drivers and the setting of innovation processes. Case studies on micro cogeneration, carbon capture and storage, consumer feedback, network regulation and emissions trading provide insights into innovation dynamics in the electricity system and are analyzed to derive strategic implications for innovation policies. A special focus is placed on drivers and barriers of change, and their consequences for shaping the innovation process. This book is an indispensable source of information for researchers and decision makers in energy and climate change as well as for lecturers and students interested in the principles and ramifications of electricity innovation dynamics.
