Everybody knows an electric car doesn’t use gasoline, but since it gets its power from the electric grid, the question remains: How clean is an electric car?

A new report from the Union of Concerned Scientists, “State of Charge: Electric Vehicles’ Global Warming Emissions and Fuel Cost Savings Across the United States,” is a first-of-its-kind analysis of the emissions EVs create from charging on an electric grid and how the cost of that charging compares to filling up a gasoline-powered vehicle. On this episode of Locus Focus we talk with Don Anair, the report’s author and senior engineer for UCS’s Clean Vehicles Program about the report’s findings and what is the future for electric vehicles.
