One of the standard criticisms aimed at electric cars is whether they actually are good for the environment when everything is taken into account. For example, people worry about the amount of energy expended and the environmental impact of actually building the car. Recent studies have shown that this balances out over a relatively short amount of the car’s lifetime.
Electric cars are still pretty much a novelty in most places, but their numbers are increasing. Electrical utilities around the world are trying to understand what will happen if and when there are millions of them on the road.
