Assuming an average electricity cost of $0.12 per kWh, the annual cost for each type of bulb would be: Incandescent: 175.2 kWh x $0.12 = $21.02 CFL: 40.88 kWh x $0.12 = $4.91 T8 Fluorescent: 329.96 kWh x $0.12 = $39.60 1. Replacement Program: The replacement program would involve replacing the existing bulbs with LED bulbs and fixtures. The ENERGY STAR Product Finder or a local hardware store website can be consulted to find similar LED replacements. 2. Estimated Energy and Cost Savings: Assuming the LED replacements use 80% less energy than the existing bulbs, the annual energy savings would be: Incandescent: 175.2 kWh x 80% = 140.16 kWh CFL: 40.88 kWh x 80% = 32.70 kWh T8 Fluorescent: 329.96 kWh x 80% = 263.97 kWh
