What are some ...[positive]... aspects of Electric cars?

they're quiet, and the cars themselves have no emissions. however, when a majority of the population starts charging them, the electricity used to power them comes from a variety of polluting factors. coal energy, gas energy, nuclear energy. if the whole world started using electric cars, we'd still have the same(if not more) polution as before because of this. the only way for them to be environmentally sound is through hydro-electric or wind energy.
