At first look, electric vehicles may appear to be the ideal replacement for gasoline and diesel cars,

whose exhaust chokes up cities' airways with pollutants. However, they still have the potential to harm the ecosystem.

Electric vehicles are only as environmentally friendly as the energy needed to produce them and 

charge their batteries in terms of greenhouse gas emissions.

However, a recent research by the International Council on Clean Transportation found that compared to gasoline-powered cars, 

electric vehicles produce lower greenhouse gas emissions throughout the course of their lifetimes (including manufacturing).

However, this variation was far more pronounced in certain locations than others.

In Europe, an electric vehicle produces up to 69% less CO2 equivalent per mile than a gasoline-powered vehicle. 

However, this percentage is 34% in India. The difference is caused by the different ways that each nation obtains its power.

France, where just 9% of power is generated by the burning of fossil fuels, is one of the countries where it is most environmentally friendly to charge an electric vehicle.
