Notes: Series A in Figure 3.3A represents the time path to consumption of a
fossil fuel stock using traditional incandescent bulbs, which results in a baseline
emissions rate, shown in Figure 3.4.
Series B illustrates a temporary reduction in emissions rates caused by the onetime
use of compact fluorescent bulbs, followed by replacement with incan-

descent bulbs and a return to the original emissions rates. Even though the reduction
in emissions rate is temporary, the savings experienced in the initial
year are carried through to the end of the time period, and the atmosphere has
less carbon in every time step than it would without the reduction in the initial
time period. Thus, there is a permanent increase in the fossil fuel stocks in every
time step and a permanent decrease in the carbon in the atmosphere.
