Carbon emissions from generating electricity for electric vehicles vary greatly across the individual US states

Green Car Congress

by Michael Sivak, Sivak Applied Research The overall advantage of battery electric over gasoline vehicles, in terms of well-to-wheels emissions of greenhouse gases, has been well documented. However, the emissions of electric vehicles depend greatly on the energy source used to generate the electricity that powers them.

Emissions Analytics argues that current Pareto-efficient solution for decarbonization would be hybrids, not BEVs, based on do-no-harm

Green Car Congress

On this basis, and of Pareto efficiency, Emissions Analytics argues, until battery-electric vehicles can reach certain performance characteristics, government and industry support should switch immediately from EVs to full hybrids to create maximum welfare. The test cycle was made up of five repeats of the EQUA cycle, totalling 741 km.
