Electricity Decentralization in the European Union: Towards Zero Carbon and Energy Transition, Second Edition examines progress in decentralization across the European Union, with each chapter focusing on developments and innovations in a specific country. Sections provide an overview of the current role and state of smart grids, the conceptualization of energy transition, and specific cases across all EU states. Across the chapters, regulatory frameworks are assessed to identify to what extent it is conducive to decentralization, with specific outcomes of decentralization covered in detail, including deployment of smart grids and meters, demand response, electric vehicles, and storage. The book highlights how specific EU member states are progressing towards deployment of these tools and technologies, along with the specific needs and regulatory barriers in each and recommendations for how regulation can be more encouraging. In addition, electricity interconnections in the EU are considered as a vital step towards decentralization in order to boost energy security and energy efficiency. Finally, the book includes a detailed examination of data protection concerns that arise from the advent of new technologies that collect personal information, such as smart grids, assessing current regulation on data protection and identifying areas for improvement, as well as innovative finance options for sustainable energy.
