European environmental and energy policies are currently challenged by two mutually dependent issues: CO2 abatement and the completion of the Internal Market for energy. Both will lead to substantial structural changes in the energy supply industry and in the wider economy. The purpose of this book is to analyze the interaction between CO2 abatement, economic structural change and the completion of the European Internal Market. This involves not only significant general equilibrium effects, but also technological changes, especially in the electricity supply sector. The simulation results indicate that the effects of measures to reduce European CO2 emissions depend considerably on the structure of the electricity supply system.European environmental and energy policies are currently challenged by two mutually dependent issues: CO2 abatement and the completion of the Internal Market for energy.
