Compact Fluorescent Light Bulbs (4 hrs per day usage)

The Energy Saved By Replacing A 100-Watt Incandescent Bulb With An Equivalent Compact Fluorescent Over Its Lifetime Is Sufficient To Drive A Toyota Prius From New York To San Francisco. A Standard (13 Watt) CFL Would Reduce Electricity Bills By $30 During Its Life, Which Is 10 Times As Long As An Incandescent Bulb. If The World Transitions Into CFLs We Would See A 12% Reduction In The Global Electricity Use And Eliminate Over 700 Coal Fired Power Plants.
