How electricity became a metaphor for modernity in the United States, inspiring authors from Mark Twain to Ralph Ellison. At the turn of the twentieth century, electricity emerged as a metaphor for modernity. Writers from Mark Twain to Ralph Ellison grappled with the idea of electricity as both life force (illumination) and death spark (electrocution). The idea that electrification created exclusively modern experiences took hold of Americans' imaginations, whether they welcomed or feared its adoption. In Power Lines, Jennifer Lieberman examines the apparently incompatible notions of electricity that coexisted in the American imagination, tracing how electricity became a common (though multifarious) symbol for modern life. Lieberman examines a series of moments of technical change when electricity accrued new social meanings, plotting both power lines and the power of narrative lines in American life and literature. While discussing the social construction of electrical systems, she offers a new interpretation of Twain's use of electricity as an organizing metaphor in A Connecticut Yankee in King Arthur's Court, describes the rhetoric surrounding the invention of electric execution, analyzes Charlotte Perkins Gilman's call for human connection in her utopian writing and in her little-known Human Work, considers the theme of electrical interconnection in Jack London's work, and shows how Ralph Ellison and Louis Mumford continued the literary tradition of electrical metaphor. Electrical power was a distinctive concept in American literary, cultural, and technological histories. For this reason, narratives about electricity were particularly evocative. Bridging the realistic and the romantic, the historical and the fantastic, these stories guide us to ask new questions about our enduring fascination with electricity and all it came to represent.

The proliferation of electric communication and power networks have drawn wires through American landscapes like vines through untended gardens since 1844. But these wire networks are more than merely the tools and infrastructure required to send electric messages and power between distinct places; the iconic lines themselves send powerful messages. The wiry webs above our heads and the towers rhythmically striding along the horizon symbolize the ambiguous effects of widespread industrialization and the shifting values of electricity and landscape in the American mind. In Power-Lined Daniel L. Wuebben weaves together personal narrative, historical research, cultural analysis, and social science to provide a sweeping investigation of the varied influence of overhead wires on the American landscape and the American mind. Wuebben shows that overhead wires--from Morse's telegraph to our high-voltage grid--not only carry electricity between American places but also create electrified spaces that signify and complicate notions of technology, nature, progress, and, most recently, renewable energy infrastructure. Power-Lined exposes the subtle influences wrought by the wiring of the nation and shows that, even in this age of wireless devices, perceptions of overhead lines may be key in progressing toward a more sustainable energy future.

Most people know that electric power lines, like the wiring in our homes, can cause serious electric shocks if we're not careful. Many people also want to know whether the electric and magnetic fields (EMF) produced by power lines and other electrical devices cause health effects. The purpose of this booklet is to answer some common questions that the Bonneville Power Administration (BPA) receives about the possible effects of power lines on health. First, some basic electrical terms are defined, and electric and magnetic fields are debed. Next, answers are given to several questions about recent scientific studies. Some important information about electrical safety follows. We then describe how BPA is addressing public concerns about potential health effects of power lines. The last section tells you how to obtain more detailed information about the health and safety issues summarized in this booklet.

How high energy consumption transformed postwar Phoenix and deepened inequalities in the American Southwest In 1940, Phoenix was a small, agricultural city of sixty-five thousand, and the Navajo Reservation was an open landscape of scattered sheepherders. Forty years later, Phoenix had blossomed into a metropolis of 1.5 million people and the territory of the Navajo Nation was home to two of the largest strip mines in the world. Five coal-burning power plants surrounded the reservation, generating electricity for export to Phoenix, Los Angeles, and other cities. Exploring the postwar developments of these two very different landscapes, Power Lines tells the story of the far-reaching environmental and social inequalities of metropolitan growth, and the roots of the contemporary coal-fueled climate change crisis. Andrew Needham explains how inexpensive electricity became a requirement for modern life in Phoenix—driving assembly lines and cooling the oppressive heat. Navajo officials initially hoped energy development would improve their lands too, but as ash piles marked their landscape, air pollution filled the skies, and almost half of Navajo households remained without electricity, many Navajos came to view power lines as a sign of their subordination in the Southwest. Drawing together urban, environmental, and American Indian history, Needham demonstrates how power lines created unequal connections between distant landscapes and how environmental changes associated with suburbanization reached far beyond the metropolitan frontier. Needham also offers a new account of postwar inequality, arguing that residents of the metropolitan periphery suffered similar patterns of marginalization as those faced in America's inner cities. Telling how coal from Indian lands became the fuel of modernity in the Southwest, Power Lines explores the dramatic effects that this energy system has had on the people and environment of the region.
