Considering Overall Life-Cycles Electric Cars Pollute More


Charging chemical car batteries using electricity from coal-fired power stations generates more pollution than running regular combustion engine vehicles

The public’s apathy for electric vehicles might turn out to be a good thing, with experts once again claiming that charging chemical car batteries using electricity from coal-fired power stations generates more pollution than building and running regular combustion engine vehicles.

Furthermore, manufacturing processes in electric car factories produce more toxic waste than the leftovers that come from building traditional models, with the production of electric vehicles having the potential to produce twice the level of global warming gasses on a per vehicle basis.

Looking at the entire life-cycle of cars – from cradle-to-grave and even cradle-to-cradle – in terms of the potential for pollution electric cars were at best equal to internal combustion models and often worse.

In fact, battery chemicals and their many manufacturing difficulties mean electric cars have already done most of their damaging-the-world stuff in the factory before they even hit the road. Producing batteries and electric motors requires a lot of precious metals and toxic minerals such as nickel, copper and aluminium.

In regions where fossil fuels are the main sources of power, electric cars offer no benefits and may even cause more harm. It is counter-productive to promote electric vehicles in regions where electricity is primarily produced from lignite, coal or even heavy oil combustion.

In Europe, where electricity is produced in a number of different ways, electric cars do offer environmental benefits when compared with cars with internal combustion engines.

The longer an electric car in Europe stays mobile, the greater it’s leading edge over petrol and diesel engines. An electric car’s longevity depends a great deal on how long its battery lasts, not least since it is very expensive to replace them. Batteries are gradually getting better, which could result in electric cars being used for longer.

However, as petrol and diesel engines are also improving, the relationships between the different types of vehicles are not constant.
