Answer

Brief Explanations:

Conventional bulbs have the lowest initial cost at $0.50 but high power - consumption (60 watts). LED bulbs have low energy - consumption (8 watts) but higher initial cost ($2.50). Compact fluorescents cost $1.50 per bulb and consume 15 watts of power. They are a better compromise between low initial cost and low energy - consumption compared to the other two.

Answer:

D. Compact fluorescents are the best compromise between initial cost and energy consumption.
