This book provides an analysis of the European policy approach to combined heat and power (CHP), a highly efficient technology used by all EU Member States for the needs of generating electricity and heat. European Law on Combined Heat and Power carries out an assessment of the European legal and policy measures on CHP, evaluating how it has changed over the years through progress and decline in specific member states. Over the course of the book, Sokołowski explores all aspects of CHP, examining the types of measures used to steer the growth of cogeneration in the EU and the policies and regulatory tools that have influenced its development. He also assesses the specific role of CHP in the liberalisation of the internal energy market and EU action on climate and sustainability. Finally, by delivering his notions of "cogenatives", "cogenmunities", or "Micro-Collective-Flexible-Smart-High-Efficiency cogeneration", Sokołowski considers how the new EU energy package – "Clean energy for all Europeans" – will shape future developments. This book will be of great interest to students and scholars of energy law and regulation, combined heat and power and energy efficiency, as well as policy makers and energy experts working in the CHP sector.
