The excessive growth of greenhouse gases, among the most dangerous to the Earth and human health itself, has forced the development of green technologies with the aim to solve this issue. Since one of the most negative factors, which has a big impact to the increasing of the pollution is the transports field, both public and private, the carmakers have decided to introduce, in their production lines, electric vehicles (EV), both hybrid (HEV) and fully electric (BEV). Despite the goal is to reduce the greenhouses gases, the introduction of zero emission vehicles is not the solution to the problem, but only a starting point.
