This two-volume book offers a broad range of discussions on the immense challenge of climate change, one confronting every country on the planet and forcing them to find a path towards a sustainable future that will not have disastrous consequences in relation to our chances of survival. It also presents a snapshot of the status quo, which reflects all the decisions and measures taken to date. Analyzing the consequences of the steps that will shape our future, the two volumes also reflect on important decisions at a global level that have already been taken.  In this first volume on green energy, decarbonization, and forecasting the green transition, respected international scholars analyze various technical aspects of and alternatives to the so-called “green energy transition,� as well as measures intended to help reach the ambitious goal of net zero emissions within the next thirty years. Throughout the 13 chapters, the authors forecast future scenarios for the use of alternative energy sources. Additionally, the book discusses questions regarding the suitability of current measures and presents innovative alternatives that have remained largely overlooked. This book is a must-read for scholars, researchers and students, as well as policymakers interested in a better understanding of climate change, present scenarios, and alternative solutions and measures.
