Trading in your regular light bulbs for compact fluorescent light bulbs is by far the most common way of saving power and money on your electrical bills. Please keep in mind though that this is a long term make money saving technique. Most everyone has seen the commercials by GE or Energy Star trying to get you to replace all of your regular incandescent light bulbs with the CFL (Compact Fluorescent Light) bulbs. What some people don’t see, but should, are the money figures it produces on saving.
Compact Fluorescent Light bulbs use 75% less energy than traditional incandescent light bulbs and they do this by using a lesser wattage than a incandescent bulb. A 13 watt GE spiral bulb gives the same amount of light as a 60 watt incandescent bulb. CFL bulbs also last longer, up to 10 times longer, which equals around 15,000 hours. Wait, I know what you’re thinking, “CFL bulbs cost a lot more than regular incandescent bulbs”. In short term, yes, CFL bulbs do cost more than incandescent bulbs. Remember though, this is a long term savings technique, so it will take time to earn money through this technique.
Here is how the savings works. The GE CFL bulb costs $3.77 while a regular incandescent bulb costs $0.27. Over the life of the GE bulb, you will replace the incandescent bulb and average of 7 times. So that totals the incandescent at $2.16 and the CFL is still at $3.77.
Now comes the energy costs, in which the CFL exceeds. Based on $0.10 per kWh on a 8,000 hour bulb, the GE CFL will run $12 in energy costs while the regular incandescent bulb will run $48 in energy costs. Now the GE bulb is at $15.77 and the incandescent is at $50.16.
So over the life of one $3.77 Compact Fluorescent Light bulb you will end up make money, saving a estimated total of $34.39 while helping the environment at the same time. Keep in mind that this is just one bulb, if you replace all the bulbs in your house you can multiply however many bulbs by $34.39. If every household in the U.S. replaced one bulb with a CFL, we would save an estimated $600 million a year in energy costs.
