THE FUTURE ENERGY SUPPLY OF TRANSPORT

TRANSPORTERNAS FRAMTIDA ENERGIFOERSOERJNING

Energy consumption in the transport sector is dominated by the car. According to OECD forecasts, in 1980 there will be 373M cars in the world, and in 2000, 524M. A car weighing 1300 kg needs about 30000 kwh in manufacture, and uses about the same in two years. World oil production in 1974 was 27000 twh. The size of reserves is open to discussion, but one estimate says oil reserves will suffice for 40 years. Alternative forms of energy are coal and oil in shale; the latter is expensive to exploit and environmentally inimical. Methyl alcohol, which can be made from coal, refuse, wood etc, has good potential as fuel. Road traffic can be made more efficient in its use of fuel by: 1. Greater use of public transport, 2. Lower specific fuel consumption, 3. Improvement of the conventional car's fuel efficiency, 4. New types of engine or transmission. 3 and 4 have greater practical potential than 1 and 2. 20% of total energy consumption goes on transport. In the USA where 50% of oil consumption is in the transport sector, improvements will have a great effect on total oil consumption; in Sweden where the corresponding figure is 15%, the benefits will not be so great. /TRRL/
