Having an electrical car you are not eco for sure

The electrical cars are eco. But this fact doesn't mean that air pollution or oxygen consumption does not occur after their use. And why it's so? Well, while entire world is talking about eco ways of being and eco products, our global economy is still running mainly on the electricity made in power stations fueled with fossil fuels such as gas, coal or tar. So this implies that you are still doing pollution when you charge your car with electricity because that electricity is produced with fossil fuels.
