Assuming an electricity rate of $0.12 per kilowatt-hour, running a 70-watt light bulb for 1 hour would cost $0.0084 or 0.84 cents. This calculation is done by converting watts to kilowatts (70W = 0.07 kW) and then multiplying by the cost per kilowatt-hour.
To remove the same amount of heat as a light bulb in an hour (about 60 watts), approximately 200 ml of sweat would need to evaporate per hour. This calculation is based on the heat of vaporization of sweat and the rate of heat production by a light bulb.
"A standard light bulb I would consider to be a 60 watt light bulb, and kilowatts are the amount of usage in a light bulb. From my research I have found that a standard 60 watt light bulb uses approximately 1.44 Kilowatts per hour."
To calculate the cost of running a 100W light bulb for 24 hours, first convert the wattage to kilowatts (100W = 0.1 kW). Then calculate the energy consumed in kilowatt-hours (0.1 kW * 24 h = 2.4 kWh). Finally, multiply the energy consumed (2.4 kWh) by the cost per kilowatt-hour ($0.080) to find the total cost ($0.080 * 2.4 kWh = $0.192).
Your question is rather like asking, 'How many miles per hour do you do in one hour?' A watt is simply the rate at which you use energy or do work, and it is the same regardless of over what period it is measured.
Simple 10,000 hours cause it completes 1 unit in 10 hours.....
To calculate the cost per hour to use a 150 watt light bulb, you would first need to know your electricity rate per kilowatt-hour (kWh). Once you have that, you can convert the wattage of the light bulb to kilowatts (0.150 kW) and multiply it by the electricity rate to determine the cost per hour. Keep in mind that rates vary depending on your location and energy provider.
The cost of electricity for a light bulb being on for a long time depends on the wattage of the bulb, the electricity rate per kilowatt-hour, and the duration it is on. To calculate the cost, you can use the formula: (Wattage of bulb / 1000) * hours on * cost per kilowatt-hour.
You have to have three factors to calculate this cost. First what you are charged per Kw/hr from your power supplier, second the wattage size of the bulb that you want to do the calculation on and third the voltage of the bulb. Give me these and I can tell you how it costs to run the bulb per hour.
Typical home energy cost is 10 cents per kilowatt hour A 60 watt bulb running for one hour uses 60 watt hours .10 X (60/1000) = .006 cents per hour 16.66 60watt bulbs on for one hour would cost 10 cents.
1 kilowatt-hour is 1000 watt-hours and 60 watt bulb consume during 1 hour 60 watt-hours of electricity, so then it costs 0.6 cent =>60/1000=0,06*price of 1 kilowatt-hour = 0.6 cent
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.

To remove the same amount of heat as a light bulb in an hour (about 60 watts), approximately 200 ml of sweat would need to evaporate per hour. This calculation is based on the heat of vaporization of sweat and the rate of heat production by a light bulb.
A 150 watt light bulb consumes 150 watts of energy per hour when it is turned on.
That would depend on the how many watts the light bulb you are talking about. Also, it would depend on how much your power company charges for electricity.
Unfortunately this answer is dependant completely on the "kilowatt per hour" your company charges you. If I receive this information from you then i will be more than happy to answer your question. -Tychusfindlay919
Converting 14 watts to kilowatts: 14 watts x (1 kilowatt / 1000 watts) = 0.014 kilowatt. Your energy consumption for one (1) hour is 0.014 kilowatt x 1 hr, this is equal to 0.014 kilowatthour. Cost for energy consumption: 0.014 kilowatthour X (20.52 cents / kilowatthour) : 0.28728 cents only
