It is fine, even if all the energy is created by fossil fuel plants:
1) Large power plants + transmission + charging your electric car + driving your wheels is usually more efficient than small ICE engines.
2) Even if the grid is dirty, if many cars are electric, once we make the grid cleaner, those cars automatically become cleaner. Otherwise, we would have to replace grid power generation & cars both.
3) Power plants are (usually) far from population centers, ICE cars spew exhaust everywhere, all the time.
Electrification of cars is a net good. All the time.
