asked the Secretary of State for Energy what percentage of the nation's final energy consumption is accounted for by private motoring, public road transport, road haulage, passenger rail services, rail freight and domestic air services.
I regret that details for the precise categories specified are not available but the following information, which relates to 1975, represents the nearest equivalent:—
| Percentage | ||
| Cars and motor cycles | … | 10·6 |
| Public service vehicles and taxis | … | 0·7 |
| Goods vehicles | … | 5·4 |
| Railways—total | … | 0·9 |
| Air services—total | … | 3·1 |
asked the Secretary of State for Energy what is the comparative energy efficiency per passenger mile of a private car carrying one person, a minibus carrying 12 persons, a double-decker carrying 70 persons, a passenger aircraft carrying 140 persons and a commuter train carrying 850 persons.
I have been asked to reply.The following is the information requested:
| Megajoules per passenger kilometre | |
| Car carrying 1 person | 3·0 —4·8 |
| Minibus carrying 12 persons | 0·6 |
| Bus carrying 70 persons | 0·15–023 |
| Aircraft carrying 140 persons | 2·2 –3·0 |
| Train carrying 850 persons | 0·24–0·45 |
The above figures are averages. The energy used by different vehicles varies greatly with the conditions of use, and with their loading. The loadings in the table are not typical of average load factors.
