Photographer John Pfahl described his perspective in this way: “I have frequently noticed that the electric power companies have chosen the most picturesque locations in America in which to situate their enormous plants. This is likely due to a need for rivers and waterfalls to propel their turbines, or for lakes and oceans to cool their reactors . . . power plants in the natural landscape represent only the most extreme example of man’s willful domination over the wilderness. It is the arena where the needs and ambitions of an ever-expanding population collide most forcefully with the finite resources of nature.”
