reanable energy Name:The Cost of ElectricityWatts and kilowatts are measurements of the work being done as electric current passes through acircuit. The higher the wattage of an appliance or device, the more work is being done and the moreelectricity is consumed.One kilowatt is equal to one-thousand watts. You can convert using this formula:Watts / 1000 = KilowattsElectricity consumption is measured by the kilowatt-hour. This is the amount of electrical energyconverted over one hour of time.You can calculate kilowatt-hours using this formula:Kilowatts x Time in Hours = Kilowatt-hoursElectricity costs vary by region, let's use the prices shown in this sample electric bill from SouthemCalifornia Edison.EDISONSouthern California Edison CompanyP.O.
