Vehicle-to-grid has a myriad of potential benefits, though they can roughly be characterized into three central themes that align with different elements of sociotechnical systems. These themes include technical, economic, and environmental elements, and each impacts different actors and has different scopes, ranging from the individual to society. That is, V2G offers benefits in being cheaper and faster than other energy storage devices, while also offering novel economic revenues to consumers and reducing the environmental damages from both the electricity and transport sectors. Of course, many of these benefits are intertwined with other dimensions of the sociotechnical system, especially the co-evolution of the electricity grid and adoption of electric vehicles, which the chapter discusses next.
