My daughter often leaves the lights on in her room, ceiling fan with (4) 40 watt bulbs. So the light turns on at 6:30 am and if she forgets to turn it off and no one else see's it, it will be on till 4:30 pm. That's a total of 160 watts for 10 hrs. Let's do the math. 160 watts divided by 1000 to determine the kWh which is 0.16 kWh. Let's multiply the 0.16 by 10 because the fan lights were on for 10 hrs and we come up with 1.6 kWh of electrical usage. My electrical provider is Wisconsin Energies and basically the hrs she may leave the lights on would be peak hrs and that rate is $.18881 pr kWh. So let's multiply the usage of 1.6 x the rate of $.18881 and we come up to $.30.
30 cent for the lights on for a day.
It does add up but a few years back we changed to the newer style compact fluorescent with is much better.
I really never took the time to see exactly what we pay for simple things like this and for the most part it seems reasonable. We also have options to reduce our usage,,,something to think about I guess.
Now add up an electric dryer at 4400 watts doing one load a day for a month will cost me about 26 bucks
Looks like my 17" lcd pc moniter costs just over 2 cent for 3 hrs
Someone please correct me if I have errors
