    In the class of Physics we have learned that the Energy is the property of the material systems that can effect changes in it selves or in the enviroment.

    Some examples of Energy are : 

    A rock in the top of a mountain ; gravitatonial Energy

    The sun ; thermic Energy 

    A spring ; elastic Energy 

    Food ; chemical Energy 

    The unit for Energy is the Joule (J).  The conversion factor for other units are:

    1 calorie is 4,19 J

    1 Kilowatt is 3,6 x 106 J

    1 ton is 4,13 x 1010 J

    The use of Energy is related with the development of the country. We can see the data of the use of energy in different countries in:
