Electric vehicles (EVs) don't make much noise on the road, but they're generating a lot of buzz about the future of this technology and what it means for business and the environment.

Cars, buses and trucks are the second biggest source of pollution in the U.S. after electricity production. They are responsible for more than 26 percent of emissions that adversely affect the health and well-being of the population, and put communities located close to highways and other major thoroughfares at risk. These communities, typically low-income, are often plagued by elevated asthma rates and other pollution-induced health conditions.
