An article in Scientific American pointed out that replacing a 75 watt incandescent bulb with an 18 watt compact fluorescent bulb would save about 75% in the cost of electricity. Electricity is generally priced per kilowatt-hour (kW-h). Using the price of electricity where you live, and the fact that an incandescent bulb has a typical life of only ~750 hours, calculate how much money you would save over the life of one 18 watt compact fluorescent bulb (~10,000 h) versus...
