Designing the Energy System of the Future describes a pathway towards a sustainable energy supply for the world, largely based upon existing technologies, which eliminates the dangers of climate change. This system enables economic growth and an improved standard of living, even in the face of a growing population on earth. While the driver for these changes are global, the solutions for each country will have to be individualized depending on geography and available energy resources. In general, the move is towards electrification and a de-carbonization of the energy system, i.e. abandoning or replacing most fossil sources of energy. As the necessity for a secure, sustainable and affordable supply of energy for a growing population looms front and center, this book is an ideal reference. It is intended to provide a fact-based description of the presently available technology options and the most urgent additional developments.
