As the Marketing Manager, I do not have the extensive background on lighting and CFLs that some people here at NEMA possess. After hearing all talk about how CFLs will change the future for all of us and how much money people would be saving on their electric bills, I decided it was time to do a little research to see how CFLs will affect me and my bills.
My apartment holds ten 100 watt light bulbs. A 100 watt incandescent light bulb uses 100 watts of electricity per hour, while as 25 watt compact fluorescent light bulb generates an equivalent amount of light, but only uses 25 watts of electricity per hour.
Assuming each light in my apartment is on for six hours a day, I am using 6,000 watts of electricity per day (10 light bulbs X 100 watts X 6 hours). If 1 Kilowatt of electricity (1,000 watts) costs about 10 cents a day, I am spending 60 cents a day to light my apartment. Over one year, lighting my apartment will cost $219.00.
If I make the change to CFLs it will only cost $54.75 to keep my apartment lit for one year, saving me $164.25. This may not sound like I am saving a large amount of money over the course of one year, but I also live in a 625 square foot studio.
