It seems hard to justify spending $4.00 for a compact fluorescent lightbulb when an ordinary incandescent lightbulb costs 50 ¢



 It seems hard to justify spending $4.00 for a compact fluorescent lightbulb when an ordinary incandescent lightbulb costs 50 ¢. To see if this makes sense, compare a 60 W incandescent bulb lasting 1000 hours to a 15 W compact fluorescent bulb having a lifetime of 10,000 hours. Both bulbs produce the same amount of visible light and are interchangeable. If electricity costs $0.10/kWh, what is the cost - purchase plus energy - to obtain 10,000 hours of light from each type of bulb? This is called the life-cycle cost. 


Part A

Life-cyle cost of incandescent blub.

Part B

 Life-cyle cost of fluorescent blub.

Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity. According to one study of these bulbs, a compact bulb that produces as much light as a 100 W incandescent bulb uses only 23.0 W of power. The compact bulb lasts 1.00×104 hours, on the average, and costs $ 12.0 , whereas the incandescent bulb costs only 75.0 ¢, but lasts...

A 15W compact fluorescent lamp (CFL) provides the same light as a 60W incandescent lamp. Electricity costs the end user 10 cents per kW-hr. a. If an incandescent lamp costs 60 cents and the CFL costs $2, what is the "payback" period? b. Over the 9000-hr lifetime, what would be saved in carbon emissions? (280 g carbon emitted per kW-hr) c. At a (proposed) carbon tax of $50/tonne, what is the equivalent dollars saved as carbon emissions? (1 tonne =...

A 75 watt incandescent light bulb and an 18 watt compact fluorescent bulb are equally bright. How much warmer will an insulated closed 12 by 11 by 8.0 foot room get in 1.0 hour if it is lighted by an incandescent bulb than if it is lighted by a fluorescent bulb? At room temperature, the specific heat of air is 1.007 J/gC and its density is 1.2 g/L. The watt is the SI unit of power; 1 watt = 1...
