§ Mr. Buchananasked the Secretary of State for Transport how many passenger and tonne kilometres moved by road for each therm in 1964 and 1974; and how many moved by rail for each therm in 1964 and 1974.
§ Mr. HoramFigures are not readily available in this form. Energy consumption per unit of output for each mode varies widely according to type of journey, load factor and whether or not transhipment is required, and energy is only one of the many resources used in transport. We must seek the optimum use of all these resources.
