In this report a number of key questions on energy efficiency in freight transportation are raised, and answered as fully as possible. The questions deal with: - energy efficient modes of freight transportation; - transferring cargo from one mode of transportation - comparisons between electrified modes and modes that are operated with other forms of energy; Combined transports; Use of energy not only for propulsion; Impact of technological development; The impact on freight transportation of the last ten years of turbulence in the inernational energy market; and freight markets developments in quantitiy and quality. It is clear that the rules of the economy of scale apply to transportation. This means that in most cases, the mode with the largest capacity will be the most energy efficient, provided the capacity is utilized. And because of the fact that the different modes, as we normally define them, operate in different intervals of capacity, average performance characteristics will differ. Furthermore, the transportation market has different segments, with regard to sizes of shipments, types of goods, transport distances, infrastructure etc. Therefore it is not appropriate to compare national averages in performance between the different modes. Finally it can be stated, that the dramatic rise in energy prices during the last ten years, has not significantly changed the competitive situation between the different modes of freight transportation.
