If you used a bulb for just two hours a day and paid the national average of 11.5 cents per kilowatt hour, a single 12-watt LED will cost you about $1 per year. Comparable CFLs that consume about 14 watts come to $1.17 per year and about $5 a year for 60-watt incandescents in that scenario. (See formula.)
