Comprehensive study conducted by researchers from Berkeley National Laboratory showed that the average full cost of saving electricity by U.S. utility efficiency programs is 4.6 cents. Efficiency programs and participants have split the cost of saving electricity almost right down the middle—on average paying roughly 2.3 cents per kilowatt-hour each (see Figure above).
The total cost of saved electricity in the residential sector (3.3 cents per kWh) is significantly lower than in commercial and industrial sectors (5.5 cents per kWh). The total cost of energy savings varies greatly from state to state. Read more at http://newscenter.lbl.gov/
