Conservation of Energy

Energy can neither be created nor destroyed. Although it may be transformed into different forms, the amount of energy remains the same. This law is called the Law of Conservation of Energy.

For example, in a light bulb, electrical energy is converted to light energy and other forms of energy such as heat. The amount of electric energy put into the bulb is the same as the amount of light energy and heat energy combined which come out of the bulb.
