Effectiveness of presently planned emissions reductions actions. Divergence in economic growth and energy price trends from projected values. Administration emission projections reflect the first two types of uncertainty, but not the third. B C E סח D 2000 1596 to 1691 GROUPING OPTIONS TO CAPTURE INTERRACTIVE EFFECTS Examples from earlier Energy Policy Act analyses of long range (year 2010) impacts. Synergistic Options: Options that produce a greater effect when imple- - Integrated Resource Planning and R&D (i.e., ground source heat pumps) Offsetting Options: Options that partially cancel out each other when implemented jointly. Standards (i.e., commercial lighting) and Integrated Resource Planning reduce carbon emissions 1.4 percent and 3.8 percent, respectively. Together these options reduce carbon emissions 4.2 percent (rather than 5.2 percent) because IRP promotes more efficient lighting at the same time that it is being required by law through the standard.
