Why is Wells-to-Wheels analysis important with electric vehicles?
EVs and PHEVs running on electricity have zero tailpipe emissions, but emissions may be produced by the source of electrical power, such as a power plant. Electricity generation is regional, so to get an accurate picture of the emissions created by an EV it is important to look at the sources used to create electricity in a particular area. If the electricity used to charge an all-electric vehicle comes from a nonpolluting, renewable source, such as wind or solar, driving the vehicle produces no emissions.
