Energy Consumption From Manufacture to Recycling; Aspects of Material Selection for Future Personal Vehicles 785017
The paper investigates the influence of selection of materials
on the total energy consumption of a personal vehicle and explores
whether energy is conserved by providing longer service lives.
Energy consumption over a 300,000 km period is scrutinized under
separate categories of vehicle manufacture, operation, maintenance
and repair, and final disposal. Four different groups, classified
in terms of service life, weight, and choice of construction
materials, were studied on the basis of data from
government-subsidized studies; the effect of weight on energy
consumption was identified by two evaluation factors.
Results showed that vehicles with long service lives are
energy-efficient, and lightweight vehicles are particularly so.
However, the affect of weight on energy consumption was not as
strong as previously thought. The investigation suggested ways of
reducing total energy consumption by 2 to 20% (e.g., extended
service lives, extensive use of aluminum).
