We used data listed in Figure 12 on page 5 of the report. According to one of the report's authors, John Rugh, NREL's calculations of total fuel use for A/C by state are based in part upon vehicle registration data from 2000. Because of this, in order to calculate per-capita fuel use, we used population data from the U.S. Census.
