Use mean values of the material intensities of Table 12.2 to compare the number of metric tons of materials required to build a nominal 0.5 GW of new generating power by (a) nuclear, (b) single crystal solar PV power, and (c) land-based wind sources. How do these tonnages change if 0.5 GW of actual, not nominal, power is to be built?
