This is a very good question.
A Watt is a unit of power, or energy with respect to (divided by) time, and is defined as 1 Joule per second.
A 100 Watt light bulb consumes energy at a rate of 100 Joules (J) per second (s).
There are 60 seconds in every minute, and 60 minutes in every hour. So also, there are 3600 seconds in every hour (60 X 60).
100 J/s X 3600s = 360,000 J (the s cancels out in the division)
Your bulb consumes 360,000 Joules in one hour.
A measure of electrical energy equivalent to one kilowatt hour is a unit of energy equal to 3.6 million joules.
A measure of electrical energy is called a kilowatt-hour (kWh). It is commonly used to quantify electricity consumption on utility bills and represents the amount of energy used by devices over a period of time.
Electrical potential energy is the energy stored in an object due to its position in an electric field. It arises from the interaction between electric charges and is measured in joules. The potential energy is directly proportional to the voltage or electric potential difference between the charges.
To find out how much energy is transferred in an hour in joules, you need to know the power consumption of the device in watts. You can calculate the energy transferred by multiplying the power in watts by the time in hours. The formula is Energy (joules) = Power (watts) x Time (seconds).
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
A measure of electrical energy equivalent to one kilowatt hour is a unit of energy equal to 3.6 million joules.
In physics, the total amount of energy is measured in joules. The rate of energy use - joules/second - is the power, the unit is also known as watt. Electricity companies tend to use another measure for energy use: the kilowatt-hour (kWh), which of course is equal to 3.6 million joules.
The unit used to describe the amount of electrical energy provided by an energy source is the kilowatt-hour (kWh). It represents the amount of energy consumed or produced by using 1 kilowatt of power for 1 hour.

The watt is a unit of measurement as related to electrical energy. eg: one (1) kilowatt hour equals 3,412 BTUs.Another AnswerEnergy is not measured in watts, but in joules. A watt is used to measure power.
A Watts is a measurement of power or energy usage represented by W. When you see this on an electrical device, say a sticker on an appliance, it tells you how much energy it will use in watts, or Joules per hour. This allows the consumer to compare similar appliances based on energy usage.
5 HP MOTOR WOULD CONSUME ENERGY OF 1342800 JOULES IN AN HOUR.EXPLANATION :-1 HP = 746 WATTSTHEREFORE 5 HP = 3730 WATTS.= 373O Joules/sec (since 1WATT= 1 Joules/sec)=3730 x 3600= 13428000 Joules/ hour.
1 joule = 1 watt-secondkilo = 1,000hour = 3,600 seconds1 kilowatt-hour = 1,000 x watt x (3,600 seconds) = 3,600,000 joules
1 calorie = 4.184 joules 1 kilowatt-hour (kWh) = 3.6 million joules 1 British thermal unit (BTU) = 1,055 joules
This question has been answered in wikipedia:A joule is ...The work required to continuously produce one watt of power for one second; or one watt second (W·s) (compare kilowatt hour). This relationship can be used to define the watt.http:/en.wikipedia.org/wiki/JouleThe kilowatt hour, or kilowatt-hour, (symbol kW·h, kWh) is a unit of energy equal to 3,600,000 joules. Energy in watt hours is the multiplication of power in watts and time in hours.http:/en.wikipedia.org/wiki/Kilowatt_hour
