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.

∙ 13y agoThe cost will surely vary from one country to another. Look at your electricity bill, and divide the total cost by the number of kWh you have been charged. That will give you the cost per kWh.

cost= rate * time or
cost = power * time
(help me please)

Energy is power times time, the cost is energy times the rate.
example: a 100 watt bulb run for 24 hours uses 100x24 watt-hours or 2.4 kilowatt-hours (units) of energy. At a rate of £0.15 per unit the cost is 2.4 x £0.15 or £0.36.

∙ 9y agoIt depends entirely upon what type of energy, where you are, when the energy is being used, and what type of system you have to use it. All of these things affect pricing.
<<>> Power is measured in watts, while energy is measured in watt-hours or kilowatt-hours, among other things. The power (watts) tells you how fast energy is being used, then that is multiplied by the time to find the energy and the cost.
If a 1 watt load (a bulb or anything else) runs for 1000 hours, that represents the same amount of energy as 1000 watts running for 1 hour and that is a kilowatt-hour, also called a Unit, costing 10-15 p or cents.

How much does 1 volt of electricity cost?
Electricity is not sold by the volt. It is sold by the watt, a unit of power. One watt equals one volt-ampere.
What is 1 watt power?
One Watt means that 1 Joule (a unit of energy) is converted every second.
Defined as one joule of energy expended over one second of time?
A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.A joule / second is a watt. The watt is a unit of power. In general terms, power means energy expended, produced, or transferred, per time unit.
A 60 watt light bulb runs for 5 seconds how much energy does it use?
That would be 40x60 watt-seconds, also known as Joules, so it's 2400 Joules of energy. 3.6 MegaJoules is equal to one kilowatt-hour, also known as 1 unit.
Is the work or energy required to produce one watt?
A watt is a unit of power - how fast energy is transferred, or in other words, how fast work is done. "Work" can simply be understood as a transfer of certain types of energy.
How much is one Watt of energy?
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. 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. 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. The international unit for energy is the joule. One watt is an energy transfer of one joule per second.
How much energy will it take to produce one watt of power in one second?
1 watt means 1 joule/second. To produce 1 watt means that every second, 1 joule of energy is produced.
Does one watt is the work or energy required to produce one watt of power in one second?
No. One watt is one joule/second.
How much does a 60 watt light bulb use 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.
What is 1 watt of power?
One Watt is one Joule of energy transfered every second. So the Watt is the unit of enegery transfer.
What is one joule of energy transformed in one second called?
That is called a Watt. The Watt is a unit of power.
How does watt and joule relate?
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
Work or energy required to produce one watt of power in one second?
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.
How many watts does a 60w light bulb consume in a day - in pound sterling?
A 60 Watt light bulb consumes electrical energy. If you leave is on for 24 hours, it consumes 60 x 24 = 1440 Watt-Hours, or 1.44 Kilowatt-Hours. If you want to know how much money this much energy costs, look on your last electricity bill. There it will give the cost of one Kilowatt-Hour.
How long is a watt hour?
A watt hour is a unit of energy, not time -so you cannot ask how 'long' it is. The time taken to consume a watt hour of energy depends upon the rate (i.e. the power) at which it is consumed, expressed in watts. A watt hour is defined as the amount of energy consumed, over a period of one hour, at the rate of one watt.
How much is a watt?
A watt is one joule of energy used every second. In electronics, applying 1 volt across a 1 ohm resistor will produce 1 W of heat.
What is the unit of watt?
A watt is a unit of power, and it can also be expressed as one joule of energy per second.
