Internal combustion is dirty; smog, leaking fluids and the whole oil industry process. This is now a Global issue with much of the world looking toward electric solutions. An electric car can be charged with the same amount of electricity that is used just to refine gasoline, and the rest of the entire oil exploration, extraction, spilling, transporting, and pumping process can be eliminated.
Electric vehicles have a very long life with very little maintenance. With electricity being the equivalent of about 1/5th the cost of gas (or less), it makes cents at a personal level and even more at a national and global level. Each year, we send about $300-400B out of our country for oil. All that money could be kept in our economy. Much more than that is spent when including money for defense to protect the oil sources and routes, on health care to pay for resulting health issues, and on monitoring, regulating and cleaning up the mess. "We're better off buying foreign cars that run on U.S. electrons than buying U.S. cars that run on foreign oil."
