Other Important Information

How Much Energy/Electricity Will I Save With a 7W CFL MiniTwist?

The estimated savings is the product of the estimated number of kilowatt hours saved times the cost per kilowatt hour. Kilowatt hours saved are determined by taking the difference between the traditional incandescent bulb wattage and the watts used by the equivalent CFL, times the estimated number of hours of use, divided by 1,000. The average cost per kWh varies widely across the country from 7¢ in Missouri to almost 26¢ in Hawaii according to the Department of Energy (DoE). The average cost nationwide is about 11¢.

Savings for this bulb are calculated using a more conservative 10¢ per kWh:

(40W-7W) * 10,000 / 1,000 * $0.10 = $33

You can substitute your actual cost per kWh ($0.10 in the calculation above) from your electric bill or using information from the DoE. In addition, you can add in the cost of all of the incandescent bulbs you would buy over the life of this 10,000 hour CFL. This likely will increase your lifetime savings by $5-10.
