Cultures of Energy: North American’s electric grid is going through a period of unprecedented transition. Bakke presents a compelling overview of the complex history of the electric grid, with an emphasis on why culture and cultural change matter to the particular ways in which the grid has changed over time. These effects are felt even more pointedly today as renewable forms of energy enter our electricity system in record number. These are forcing rapid adaptation upon a system more given to careful, steady, and considered improvement. Bakke recommends approaching this energy transition with open arms and a sharp mind, keeping popular sentiments and radical technologies firmly in our sights as we work to both imagine and produce real reform.
