It helps the environment because electric vehicles have zero emissions. The only pollution that can be caused by electric vehicles is the pollution created by utility companies to make the electricity this is still a lot less then when using a gasoline car. Also if you use solar panels you can make it so there is absolutely no pollution.
They currently can not. There are no workable electric cars on the market today. The few that can be seen are cute toys that can go up to several miles a day. The current technology for batteries and the weight to power ratios are not yet workable for these cars.
