By now you have probably heard that you can save some money on your utility bills just by changing out some light bulbs. But you are still a little skeptical. Just how much money could I save, you wonder. So I am going to provide you with the formula, and a way to see how quickly the investment in compact fluorescent bulbs can pay off for you.
Say you have a typical 4 light fixture in the bathroom. We will assume that you have four 60W bulbs in the fixture.
The following calculation can show you just how much these bulbs are costing you for every hour that they are burning.
Cost per Kilowatt-Hour x Wattage of Appliance / 1000 x Hours Appliance is Running
Cost per Kilowatt-Hour( according to my bill) = $. 1129
4 X 60W Bulbs = 2400W Divided by 1000( Kilowatt is 1000 watts) = 0.2709 Multiplied by the Hours it is running or on = 4
Cost per Kilowatt-Hour multiplied by wattage divided by 1000 multiplied by the hours it is on = cost per hour.
Electricity is billed by the power company based on kilowatt hours.
