In the late 1890s, at the dawn of the automobile era, steam, gasoline, and electric cars all competed to become the dominant automotive technology. By the early 1900s, the battle was over and internal combustion had won. Was the electric car ever a viable competitor? What characteristics of late nineteenth-century American society led to the choice of internal combustion over its steam and electric competitors? And might not other factors, under slightly differing initial conditions, have led to the adoption of one of the other motive powers as the technological standard for the American automobile?

David A. Kirsch examines the relationship of technology, society, and environment to choice, policy, and outcome in the history of American transportation. He takes the history of the Electric Vehicle Company as a starting point for a vision of an “alternative” automotive system in which gasoline and electric vehicles would have each been used to supply different kinds of transport services. Kirsch examines both the support—and lack thereof—for electric vehicles by the electric utility industry. Turning to the history of the electric truck, he explores the demise of the idea that different forms of transportation technology might coexist, each in its own distinct sphere of service.

A main argument throughout Kirsch’s book is that technological superiority cannot be determined devoid of social context. In the case of the automobile, technological superiority ultimately was located in the hearts and minds of engineers, consumers and drivers; it was not programmed inexorably into the chemical bonds of a gallon of refined petroleum. Finally, Kirsch connects the historic choice of internal combustion over electricity to current debates about the social and environmental impacts of the automobile, the introduction of new hybrid vehicles, and the continuing evolution of the American transportation system.

For the first time in half a century, real transformative innovations are coming to our world of passenger transportation. The convergence of new shared mobility services with automated and electric vehicles promises to significantly reshape our lives and communities for the better—or for the worse.

The dream scenario could bring huge public and private benefits, including more transportation choices, greater affordability and accessibility, and healthier, more livable cities, along with reduced greenhouse gas emissions. The nightmare scenario could bring more urban sprawl, energy use, greenhouse gas emissions, and unhealthy cities and individuals.

In Three Revolutions, transportation expert Dan Sperling, along with seven other leaders in the field, share research–based insights on potential public benefits and impacts of the three transportation revolutions. They describe innovative ideas and partnerships, and explore the role government policy can play in steering the new transportation paradigm toward the public interest—toward our dream scenario of social equity, environmental sustainability, and urban livability.

Many factors will influence these revolutions—including the willingness of travelers to share rides and eschew car ownership; continuing reductions in battery, fuel cell, and automation costs; and the adaptiveness of companies. But one of the most important factors is policy.

Three Revolutions offers policy recommendations and provides insight and knowledge that could lead to wiser choices by all. With this book, Sperling and his collaborators hope to steer these revolutions toward the public interest and a better quality of life for everyone.
