Century Wind Project, Blairsburg, Iowa, from the series American Power

Wind turbines outnumber people in the tiny town of Blairsburg, Iowa; their massive rotating blades redefine the horizon in this part of the heartland. Mitch Epstein's sweeping view focuses on the line between a residential neighborhood and farmland, where wind turbines produce enough energy to serve 100,000 homes. This photograph and others in Epstein's American Power series contemplate the relationship between energy production and American society and the ongoing debate about power sources and the realities of climate change.
