The appeal of electric cars is straightforward: Owners get to save money by skipping trips to the gas station and feel good about doing their part to cut carbon emissions. That's part of the reason why U.S. sales are currently soaring, with electric vehicles expected to make up 10 percent of the cars and light-duty trucks on roads in 2030. This is good news for the climate, since transportation is the single largest source of emissions in the country.
The decision to switch to an electric-powered vehicle benefits 9 out of 10 U.S. drivers, but the lowest income Americans get left behind, according to the results of a new study from the University of Michigan.
