gulfnews : A great green solution to transport woes: "Fifty years ago, transport energy in the world was 15 to 20 per cent of total energy consumption. Today it is probably over 50 per cent and increasing. Therefore using public transport and the train systems in particular are the way to optimise energy consumption, not only to cut costs but to maintain and improve the environment and air quality and hence public health."
