Electric cars have no exhaust pipes and therefore don't emit nitrous oxides and other harsh particles into the atmosphere. Beyond the environmental benefits of electric cars are the huge cost savings - owners are exempt from paying the congestion charge, parking is free in central London and insurance rates are cheaper. Plus with the new road tax penalizing car owners of gas guzzling cars that emit more than 130g of CO2/km, from 2010 onwards, now is as good a time as any to think about going green on the car front.
