How much energy has been saved because of the CFL?



  1. 0 Votes

    Current CFL bulbs save about $30 worth of energy per bulb. This amounts to nearly a 75% savings over a CFL bulb’s lifetime. It is currently estimated that if every American household switched over to CFL bulbs, the United States would save approximately from $600 million to $800 million. In addition, the consumer realizes a long-term savings because each CFL bulb can last for as long as years and a traditional incandescent bulb requires replacement after about 2,000 hours.

    Though it’s impossible to know how much energy has been saved because of CFLs (Compact Flourescent Lamps) because we don’t know how many people use them, what I can tell you is how much energy it saves on a case-by-case basis.

    CFLs use anywhere between 20-33% of the amount of energy that equivalent incandescent bulbs use. According to wikipedia (who cites the Energy Information Administration–see second URL), “Since lighting accounted for approximately 9% of household electricity usage in the United States in 2001, widespread use of CFLs could save as much as 7% of total US household usage.”
