The adoption of large numbers of electric vehicles (EVs) offers many benefits for cities, including cleaner air and the opportunity to reduce greenhouse gas emissions. Electric vehicles are far cleaner than gasoline-powered cars, with lower greenhouse gas emissions and lower emissions of the pollutants that contribute to smog and par- ticulate matter. The number of EVs on America’s streets is at an all-time high. Throughout 2016, sales of plug-in electric vehicles increased nearly 38 percent. In 2017, sales of electric vehicles were up again, increasing 32 percent over the year. The introduction of the Chevy Bolt, Tesla’s Model 3 and other affordable, long-range electric vehicles suggests that growth in EV sales is just beginning. In fact, Chevrolet’s Bolt EV was named Motor Trend ’s 2017 Car of the Year.
