To know if this is the best alternative we must first know how this car works and what are its differences from petrol fuelled cars.

An electric car is identical to a standard car in aspect. The big difference is that it is powered by an electric motor rather than a petrol engine. Under the hood, one can clearly notice the differences. What you immediately notice is the...
