HL Deb 05 October 1976 vol 374 cc1285-6WA
Lord IRONSIDE

asked Her Majesty's Government:

(1) What is the total number of battery powered electric road vehicles in Government service at the present time; how they are allocated between the Departments and in each case what proportion is licensed for use on the public highway; and

(2) whether they have carried out any comparative evaluation with internal combustion engined vehicles and so what conclusions have been drawn.

Lord WINTERBOTTOM

Details of the battery-electric road vehicles in service in Government establishments are not available, nor is the number licensed to operate on public roads. The latter number will be very small. Most Government-operated electric vehicles will be concerned with the movement of stores.

Electric vehicles are designed for a different duty role from those conventionally powered and direct comparison is therefore not possible. But as an indication the conclusion drawn from a recent comparison of buses in not dissimilar roles was that the electric version consumes 1.7 times as much energy overall.
