Energy suppliers of electricity and natural gas will give you a cost per kilowatthour, and your usage is metered. With coal you buy it by the ton, so you need to know how many BTU that grade of coal will give per ton. With oil, the energy content of that type of petroleum product should be available from the supplier, per gallon or 100 gallons probably. You would have to keep a check on how much you are using over a period.
One watt of energy is equivalent to 1 calorie.
One watt of energy is equivalent to 0.86 calories.
The work or energy required to produce one watt is equal to one joule per second. This is because one watt is defined as the rate at which work is done or energy is transferred, with one watt equivalent to one joule of energy transferred per second.
One watt of energy expenditure burns approximately 4.18 calories.
One watt is equivalent to one joule of energy being transferred in one second. This is because a watt is defined as one joule of energy being transferred per second. So, when a device consumes one watt of power, it is using energy at a rate of one joule per second.
A watt is a unit of power, not of energy. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.A watt is a unit of power, not of energy.

1 watt means 1 joule/second. To produce 1 watt means that every second, 1 joule of energy is produced.

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.
No. One watt is one joule/second.

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.
You have all the right words, but the concept is backwards. Energy is the amount, power is the rate of energy. One watt of power is required to move one joule of energy in one second.
That is called a Watt. The Watt is a unit of power.
One watt of energy expenditure burns approximately 4.18 calories.
