Energy Saving Facts

If every household in the U.S. were to replace one 60 watt incandescent light bulb with a 14 watt compact fluorescent bulb, the results in energy use and the effects on the environment can be seen below.

60 Watt Incandescent Bulb vs 14 Watt Compact Fluorescent Bulb
46 Watts
1 Hours/Day
46 Watts/Day
365 Days
16,790 Watts/Year or 16.79 KWh

16.79 Kilowatt hours x 109,902,090 U.S. households = 1.85 billion KWh annually

This annual kilowatt hour savings would be the equivalent of removing 173,100 households from our nation’s power grid.

Environmental Impact

This annual kilowatt hour savings would result in the reduction of CO2 emissions by 2.9 billion pounds.
That would be the equivalent of removing 253,509 cars from our nation’s roadways.
