| Technology | Efficiencya | Costb | Proposed Tax Credit |
| Electric Water Heater | 0.88 EF | $350 | None |
| Heat Pump Water Heater | 2.60 EF | $1,025 | $205 |
| Natural Gas Furnace/Central Air Conditioner | 0.80 AFUE, 10.0 SEER | $3,800 | None |
| Natural Gas Heat Pump | 1.4 GCOP, 0.7 GCOP | $8,000 | $1,000 |
| Fuel Cell | 40% | $3,625 per kilowattc | $500 per kilowatt |
| aHeating and cooling efficiency, respectively, are given for heating and cooling combination units. Units for efficiency measures
are presented as given in the Department of the Treasury's explanation of the CCTI proposals: SEER, Seasonal Energy
Efficiency Rating; EF, Energy Factor; AFUE, Annual Fuel Utilization Efficiency;
GCOP, Gas Coefficient of Performance. bCosts are given in 1998 real dollars. cSource: Energy Information Administration, Annual Energy Outlook 2000, reference case. Installed cost is for a phosphoric acid fuel cell ranging in size from 5 to 250 kilowatts of generating capacity.
