1-7 1-16 As the pie chart of Fig. 1-7 shows, lighting in the U.S. consumes 19% of the generated electricity. Compact Fluorescent Lamps (CFLs) consume power one- fourth of that consumed by the incandescent lamps for the same light output [15]. According to [13], electricity generation in the U.S. in year 2000 was approximately 3.8×10° MW-hrs. Based on this information, estimate the savings in MW-hrs annually, assuming that all lighting at present is by incandescent lamps, which are to be replaced by CFLs.
