Electric cars are the latest major development in automobile technology. They are quiet and clean, contributing to drastic reduction in air pollution in the cities, much needed in some places. And they are claimed to be environmentally friendly overall. But at the same time, they have serious disadvantages. They’re expensive, have a limited range per battery charge and their long term viability hasn't been proven. What concerns me, is that despite all the claims, I haven’t seen a convincing, in depth study that proves they’re environmentally friendly when all sources of pollution are taken into account, including car plus battery manufacture, as well as production, distribution and charging/storage of electricity. So we could well be sweeping under the carpet by shifting pollution from the cities to the countryside. Furthermore, there’s the question of energy efficiency, that is how many fuel resources are consumed and by extension, how much the planet is warming up. The electric motor is efficient, but the supply chain of its electricity may not be. Finally for the skeptics, Is there a plot by the car industry to boost sales, akin to bringing out a new model only far more so?
