An alternative to CFL bulbs and incandescent bulbs are light-emitting diode (LED) bulbs. A 100 W incandescent bulb can be replaced by a 16 W LED bulb. Both produce 1,600 lumens of light. Assuming the cost of electricity is $0.20 per kilowatt-hour, how much does it cost (in dollars) to run the LED bulb for one year if it runs for five hours a day?

Answer:

It cost $5.84 to run the LED bulb for one year if it runs for five hours a day.

Explanation:

E = Pt

  = (16W)(365*5)

  = 29200Wh

  = 29.2 kWh

cost of operation = E($0.2/kWh)

                             = (29.2 kWh)($0.2/kWh)

                             = $5.84

Therefore, It cost $5.84 to run the LED bulb for one year if it runs for five hours a day.
