Saving up to 25% on your electric bill can be as easy as changing a light bulb. By removing all your incandescent lamps and replacing them with compact flourescent lamps you will be able to cut your energy usage by 1/4. The average incandescent lamp that uses 100 watts can be changed out to a CFL that has the same light output and only uses 23 watts.
In the average home the lighting is responsible for about 1/3 of your power consumption. Just think about this, if your electric bill is $ 200 you would save $ 50 a month, $600 a year. The average CFL can be purchased for as low as $2 each and dimmables for $4 and the flood lamp style go from about $6 on up. With this in mind it would take only about 2 or 3 months for the new CFLs to pay for themselves. Another great thing is that CFLs will last about 10,000 hours, thats 4 or 5 years of use, that could amount to $2,400 to $3,000 savings over the life of the lamps.
