. In the graph to the right, the Energy Information Administration of the Department of Energy projects the energy consumption by sector from 1980 to 2008 with projections into the future. a. In 2008 what sector was the largest consumer of energy? Estimate the amount of energy consumed. b. In what year did the industrial and transportation sectors consume the same amount of energy? Estimate that amount. Explain what was true before that year and what is projected after that year. c. Let T(t) and I(t) represent transportation and industrial consumption, respectively, for t years. Write an inequality for the years t, when and when T(t) . I(t) T(t) , I(t) d. Projecting even further into the future, which sectors appear to intersect? If their rates of increase continue as projected, which sector will be consuming more energy after that intersection point?
