Saving Energy with CFL Light Bulbs

covers a great deal of ground. Some of the ways require constant change, change the way you do things, and other ways require a one time change. Lets look at a one time change that can reflect substantial savings.
Let’s do a comparison of Edison’s favorite, the incandescent bulb, versus the new .
Incandescent bulbs cost on average $0.50 apiece while CFL’s (compact fluorescent) cost on average $2.50 apiece. Quite a bit of difference, but the longevity of an incandescent bulb is on average 750 to 1000 hours, whereas the CFL is 10,000 to 15,000 hours. Pretty much a no brainer as to which one is the better bargain to purchase.
Now let’s look at the energy usage. A typical incandescent bulb you might have in a lamp is 60 watts while a similar CFL is 15 watts. That is a whopping 75% savings in watts used per bulb. What kind of savings can you expect if you were to change all the bulbs throughout your house?
To figure the savings we have to make certain assumptions. The average house has 30 bulbs, and average usage of 5 hours per day. With those assumptions you can save on average $6.00 per bulb per year. That is a household savings of approximately $180 per year just changing bulbs. The costs of the bulbs are already factored in.
Here is something to think about if you have a business, or commercial building. Lights are often on for 12 hours in a commercial environment so the average CFL will last 2 to 3 years. Wouldn’t you rather pay someone once every 2.5 years rather than 2 or 3 times a year to change those bulbs? Also the longer the lights are on the more you save.
Now the real wave of the future is lights, although their cost is very high, coming in at $40 to compare to our above examples. They run at about a tenth the cost of an incandescent and a little less than ½ of the CFL, coming in at a little less than $1.00 per bulb per year. ’s are rated at 50,000 hours of usage, roughly 5 times that of a CFL.
Saying all that, before you all run out to change bulbs, know that the incandescent bulbs project light farther and colors are viewed better under them. So changing them in the hall may be ok but not in my favorite reading area or my home decorating business office.
One bonus of CFL’s or LED’s are if you are thinking about or have solar panels or other green energy sources the reduced wattage will reduce the amount of panels you need, and that can be a big savings.
I hope I have shed some light…. On a sometimes confusing subject.
