Forms of energy : Energy exists in many different forms. Examples of these are: light energy, heat energy, mechanical energy, gravitational energy, electrical energy, sound energy, chemical energy, nuclear or atomic energy and so on. Each form can be converted or changed into the other forms. Total energy is sum of all forms of energy a system possesses. In the absence of magnetic, electrical and surface tension effects, the total energy of a system consists of kinetic, potential and internal energies.
Although there are many specific types of energy, the two major forms are Kinetic Energy and Potential Energy.
For example : water evaporates from the oceans, may be deposited on elevated parts of the earth, and after being released at a hydroelectric dam, it can drive turbines to produce energy in the forms of electricity. Atmospheric phenomena like wind, rain, snow, and hurricanes are all a result of energy transformations brought about by solar energy on the atmosphere of earth.
