Concerns [of some electric vehicle drivers about range] are what Connecticut officials were trying to overcome when they began a charging station incentive program a little over a year ago and joined seven other states  in a zero-emission vehicle (ZEV) initiative aimed at getting 3.3 million ZEVs on the road by 2025.

The goal is to help ameliorate climate change by using less fossil fuel, thereby lowering greenhouse gas emissions that contribute to global warming. Transportation is thought to contribute about 40 percent of greenhouse gas emissions.
