Are electric vehicles really environment friendly?

Question

They seem to be if we go by no emissions as compared to fuel fed vehicles. But don't they emit bad vapors in the air, too when the batteries are being recharged? And in the long run, what happens when billions of batteries die out and needed to be replaced? Where do you dump them or what's left of them? They would surely pollute big time. So is it really a good alternative against fuel fed vehicles?

Answer 1

Electric cars are considered to be an  eco-friendly alternative to gas-fueled cars as they are believed not to  produce  exhaust gases. But scientists have recently confirmed that electric cars may not be as environmentally friendly as they are believed to be.

Swiss Researchers recently  made a detailed life cycle of the type of lithium-ion batteries most commonly used in electric vehicles.The investigation revealed that the size of the environmental footprint relies on which sources of energy are utilized to source the vehicles. Scientists are of the view that the  biggest ecological impact is caused by the continuous recharging of the battery which is the fuel for the car.
