So my Chevy volt gets ~3 miles/kwh and 40 mpg. At $0.15/kwh and $2/gallon for gas, its just as cheap to run on gas as electricity
Now let’s ask the question if it’s cleaner to run on gas (from a global warming CO2 perspective) . The answer depends on where you are in the US. The UCS has done a study on this matter and asked what mpg do you need to achieve for it to be cleaner to run on gas than electricity; the higher the needed mpg, the cleaner the source.
Along the coasts the numbers are high (95 mpg in Ca, 75 mpg in the northwest, 83 mpg in New England) . In the middle of the country the bar is pretty low ( 35 mpg) meaning that they are the dirtiest producers of electricity
In any state with a value lower than 40 mpg, it’s cleaner to run my volt on gas than electricity
