The Theory of the Conservation of Energy states -

• Energy can be created, just not destroyed. It changes its form from one type to another.
• Energy can never be created nor destroyed. It can only change its form from one type to another.
• The total energy in our Universe changes, as different forms of energies can be transformed from each other under certain circumstances.
• Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform energies.
