“For electric vehicles, the power plant generators alimenting the electrical grind will then produce the GHGs, not the car engine itself. Concerns for GHG emissions would then shift to the source of electric power generation and away from car manufacturers.
Currently, there is a wide difference in GHGs emissions in various electrical grids, depending on the source of energy fueling the generators. The low emissions from Swedish and French grids are explained by a combination of nuclear and hydroelectric generation, while the high emissions of the Polish and US grids stem from the use of coal as a fuel in some generators. However, the emissions from the Californian grid are nearly half those of the IS average! The regional differences in emissions in the US grid are also explained by the differences in fuels used for electricity generation: California has a high proportion of hydroelectricity and nuclear plants, while in Michigan generation plants the dominant production fuels are coal and crude oil.
Anybody concerned with GHG emissions should certainly switch to electric cars in Sweden, France, and California, but should use gasoline when driving in Michigan or Poland!”
