    total savings using CFL light bulbs = $47.09

    Explanation:

    We can compare the costs of 8,000 hours of lighting:

    incandescent light bulbs

    you need 8 incandescent light bulbs to generate 8,000 hours of lighting = 8 x $0.70 = $5.60 they will consume a total of 150 watts x 8,000 hours = 1,200 kWh x $0.05 per kWh = $60 total cost = $5.60 + $60 = $65.60

    CFL light bulbs

    you need one CFL light bulb to generate 8,000 hours of lighting = $5.71 it will consume a total of 32 watts x 8,000 = 256 kWh x $0.05 = $12.80 total cost = $5.71 + $12.80 = $18.51

    total savings = $18.51 - $65.60 = - $47.09
