The following table lists one European automaker’s summary of the material content of a mid-sized family car (such as that seen in Figure 8.23). Material proxies for the vague material descriptions are given in brackets and italicized. The vehicle is gasoline-powered and weighs 1,800 kg. The data sheets of Chapter 15 provide the embodied energies of the materials: mean values are listed in the table. Table 6.8 gives the energy of use: 2.1 MJ/metric ton km, equaling 3.6 MJ/km for a car of this weight. Use this information to make an approximate comparison of embodied and use energies of the car, assuming it is driven 25,000 km per year for 10 years.
