An 11.0-W energy-efficient fluorescent lightbulb is designed to produce the
same illumination as a conventional 40.0-W incandescent lightbulb.
Assuming a cost of $0.116/kWh for energy from the electric company, how
much money does the user of the energy-efficient bulb save during 200 h of
use? (Give your answer to the nearest cent.)
In a certain city, electricity costs $0.12 per kW · h. What is the annual cost for electricity to power a lamppost for
7.50 h per day with a 100. W incandescent light bulb versus an energy efficient 25 W fluorescent bulb that produces the
same amount of light? Assume 1 year = 365 days.
100. W bulb: $
lyear
25 W bulb: $
lyear
A typical incandescent bulb costs $0.89 and lasts for about a year; a typical energy efficient fluorescent bulb costs about
$3.49 and lasts for about 3 years.
Is the additional cost of the fluorescent bulb justified?
