From greenhouse gas emissions and air pollution to deforestation, one of the leading contributors to global warming today is emissions from the transportation sector. Exploring its origins and evolution, as well as the major challenges it faces, the development of electric mobility in urban environments represents a global transition that requires a coordinated mix of policies and actions to achieve cleaner and more sustainable transportation systems. Designing safe and comfortable infrastructure for walking and cycling, promoting public transit and shared mobility, and designing more efficient streets that include electric vehicles, among other actions, are part of a growing worldwide effort to reduce carbon emissions.
Although electric vehicles were invented before gasoline and diesel cars in the first half of the 19th century, they have undergone significant technological advances over the past 20 years, reducing their costs and their environmental impact, and increasing their utility. Around 1834, Thomas Davenport developed the first battery-powered electric vehicle, building a small train on a circular track and inventing the first direct current (DC) electric motor. Although there were numerous innovations in the years that followed, battery limitations were a major obstacle. The zinc consumption of a battery was four times more expensive than the coal consumption of a steam engine, so at that time it competed with the electric motor.
