Dimmable compact fluorescent light bulbs (CFLs) are a good option if you want to save money on electricity. CFLs use a fraction of the electricity of standard incandescent bulbs, leading to lower energy bills.
Will dimmable compact fluorescent light bulbs save you money? Yes and no. A conventional 100-watt incandescent bulb dimmed to half capacity and burned four hours a day at an average electrical cost of .12 cents per kwh will cost $8.76 a year to operate plus $1.50 for the bulb. An equivalent 23-watt dimmable CFL working under the same circumstance costs only $2 to burn for a year, but $14.53 for the bulb itself.
