Some Enlightening Facts

Replacing an incandescent bulb with a compact fluorescent bulb (CFL) can prevent the following:

  • The burning of about 528 pounds of coal
  • The release of 1 ton of CO2
  • The release of 20 pounds of sulfur dioxide into the atmosphere

Replacing 3 incandescent light bulbs with CFL can eliminate 750 pounds of CO2 emissions per year.

If all US households replaced 1 incandescent bulb with one compact fluorescent bulb, one nuclear power plant could be shut down.

If US homes replaced 500 million incandescent bulbs (around the number currently used) with compact fluorescent bulbs, the US would become an energy-exporting nation.

Because compact fluorescent bulbs last much longer than incandescent bulbs, their use averts the need for 10 to 13 times their weight in metal, glass and packaging from entering landfills.

Remember, CFL’s are recyclable and are accepted at the Somerset County Hazardous Waste days and all Home Depot stores. Click on the link below to view a short video on CFL recycling by Home Depot. A short advertisement precedes the video....
