DETROIT (AP) — Making electric vehicles and their batteries is a dirty process that uses a lot of energy. But a new study says that EVs quickly make up for that with less overall emissions through two years of use than a gas-powered vehicle. The study also estimated that gas-powered vehicles cause at least twice as much environmental damage over their lifetimes as EVs, and said the benefits of EVs can be expected to increase in coming decades as clean sources of power, such as solar and wind,
