The need for a deep decarbonization of the energy sector and the associated opportunities are now increasingly recognized, with fossil fuel projects simultaneously becoming more risky business propositions. With large-scale wind and solar generation now being the cheapest options in many parts of the world, a deeply renewable electricity sector is predestined to become the main driver of this transition. Yet, misconceptions abound. In part, this can be traced back to the complexity of the electricity sector and the processes involved in its transformation, located at the intersection between grid design and operation, markets and regulations.
