Mobility of people and goods is achieved through different means of transport; among them “on the road” transport, with vehicles powered by internal combustion engine, is undoubtedly the most practiced. This is true despite the drawback, due to thermal traction, that road transport is less efficient and more polluting than most other modes of transport, comparing specific fuel consumption and harmful emissions. As a matter of fact, electric traction is 3-4 times more efficient than thermal one. The advantage is such as to largely compensate the losses occurring during the electricity production and distribution, losses greater than the correspondent ones in refining and distributing liquid and gaseous fuels. By comparing, for example, a trolley bus and a 18 m articulated bus, the electric vehicle consumes 53% less, in terms of primary energy. Achilles’s heel of the electrified road transport are the batteries; recent huge progresses in electric storage systems can overwhelm the handicap of battery’s weight. The current high cost of storage system, instead, is expected to decline in the coming years. The paper deals with a benchmark between electric traction vehicles and thermal ones, based on a big data set available in ENEA.
