Energy cannot be created or destroyed,but we can…..

transform it into other sorts of energy.

Law of Conservation of Energy: a principle in physics which states that energy cannot be created or destroyed.

Energy Transformation: the change of energy from one form to another.

The original source of energy – even for all other sources of energy is…

the SUN!!!!
