1. What is meant by the “nominal materials intensities” of a power system? What is meant by the “actual material intensities”?

2. The land area of New York (the state) is 131,255 km2 . Its population is 19.5 million and the average power consumed per capita there is 10.5 kW. What fraction of the area of the state would be taken up by wind turbines in order to meet one half of its energy needs? How many metric tons of materials would be required? Use mean values of the data in Table 12.2 to find out.
