The book provides an integrated analysis of the implications for the energy system from adapting to meet climate change targets and analyses the role of improving energy technologies for the world and the EU markets. The first part of the book sets the stage for the analysis by presenting the European and World economic and energy outlook. The second part examines the policy options available for controlling greenhouse gases in the period to 2010. Over such a relatively short period, the role of technology lies mostly in making possible the more efficient use of energy. Finally, the third part of the volume examines the longer term role of technology in the context of a case study for the power generation sector.
