Question

Compact fluorescent lightbulbs (CFLs) cost more than incandescent lightbulbs and have lower wattages than incandescent bulbs.

Which statement best describes why a homeowner would choose to pay the extra money for the CFLs?

CFLs use the same amount of energy as incandescent lights, but they last much longer and do not need to be replaced as often.
CFLs use more energy as a result of the lower wattages, but electric companies charge less for energy used in CFLs.
CFLs will cost less to run in the long term because they use less energy than the incandescent bulbs as a result of the lower wattage.
CFLs will cost less to run in the long term because they are brighter and would need to be on for fewer hours.

Answer 1

CFLs will cost less to run in the long term because they use less energy than the incandescent bulbs as a result of the lower wattage.

Explanation: Although CFLs cost more up front, their lower wattage means they consume less electricity for the same light output, so energy bills are lower over time and the bulbs pay back the extra purchase cost.
