A Watt has no cost all by itself because a Watt is a unit which is used to measure a rate of using energy. Energy has to be supplied to equipment at a certain rate to make it do the work it was designed to do. Another way of saying the same thing is that something that does work needs to use energy at a certain rate. The equipment could be an electric motor, a light bulb etc. The equipment does not even have to be powered by electricity. If it was, say, a bicycle pedalled by a human being, it might need to be given one Watt of energy in a second to move it one yard of distance on a level road, or it may need 10 Watts of energy over 10 seconds to move it 100 yards. Depending on the steepness of the hill, it might need to be given 1000 Watts of energy (= 1 kiloWatt) to move it 100 yards up a slope in 10 seconds. Saying something "takes one Watt" is like saying "A person can eat one apple in a minute." It would not cost you anything to buy the apples until the person started eating and then it would cost you the price of one apple every minute or 60 apples every hour, for as long as the apples are being eaten. So, when you calculate the cost of supplying energy, you always have to reckon-in the time over which the energy units (Watts) are being used as well as the amount of Watts taken. Most electricity is charged by the kiloWatt-Hour (kWh is the usual term) So 1 Watt-Hour would cost 1 thousandth of the price of a kiloWatt-Hour. You can find the local price of a kiloWatt-Hour of electric power in any electricity bill.
If the transformer uses 5 watts per hour you need to know what you are paying per 1000 watts from your power company. If you pay lets say $3.00 for 1000 watts then when your transformer burns 1000 watts it cost you $3.00 your cost will be $3.00 for 200 hours run time.
185 watts will use up 185 watt-hours every hour. That is 0.185 kilowatt-hours each hour, costing about £0.03
To calculate the cost of running a device that consumes 185 watts per day, you need to know the cost of electricity per kilowatt-hour. Assuming an average cost of $0.12 per kWh, running a 185-watt device for 24 hours a day would cost about $0.50 per day (185 watts / 1000 * 24 hours * $0.12).
the rule is.... run 100 watts 24/7 for 100.00/year. Your cfl will cost apx.75/year. However, while your cfl only uses 75 watts it is equivalent to apx 350 watts and produces a broad variety of colors in the spectrum making it great for growing!
Use the following formula to find the watts used. W = Amps x Volts. Divide that number by 1000. This will give you kWs. Determine how long the motor is to run and multiply this amount by the kilowatts you calculated. This will give you kW/hours. On your utility bill it will be stated how much you pay for a kW/h. Multiply that by your answer and you can estimate how much it costs you to operate the motor.

This information would be on the back of the screen. look for a number with the word WATTS after it. I would guess something between 120 and 190 watts.
It would cost $2.24 in electricity to run the computer 50 hours in a week.
A 100 horsepower electrical motor would consume 74,600 watts.

1000 watts per hour is a kilowatt hour and is usually 10 cents
it cost $347 to mine and for extra info 1400 watts of energy

Anything, as long as the sum of what you are running does not exceed 14000 watts.
2100 watts to run the refrigerator
