Wind and Biomass	69.99	1.60	92.27	2.20	129.76	2.89
Total	94.55	3.22	122.84	4.07	163.25	4.77
^aReductions are relative to the CCTI reference case which is similar to that in Energy Information Administration, Annual Energy Outlook 1999, DOE/EIA-0383(99) (Washington, DC, December 1998). ^bFor the wind and biomass tax credits, the change represents the reduction in fossil energy use for electricity generation. ^cReductions in carbon emissions from electricity are calculated by displacing marginal generating plants. ^dCogenerated electricity substitutes for purchased electricity, and total site use increases due to additional natural gas consumption.
