Dangers of Electric vehicles

Hey everyone, I would like to invite you to take part in my research about people's knowledge of the damage to the environment that electric vehicles (further EV's) do, and why they are being labeled environmentally friendly in the media, despite not knowing the real damage. So, thanks for the answers, I hope that we can learn something from this and hope that the future of an electric vehicle will be as bright as the media and the governments portray them
