When an electric vehicle is charged from the electrical grid, there are upstream emissions involved with creating the electricity. The amount of emissions is dependent on the sources used to create that electricity. Below is a map showing the approximate grid mix for each state, as well as the national average. To see estimates of well-to-wheel emissions for vehicles in a specific state, see the Department of Energy’s Alternative Fuels Data Center.

Map of the U.S. showing electricity sources by state: natural gas, coal, nuclear, wind, hydro, solar, biomass, oil, geothermal, and other fossil.
