Its a very odd and unexpected law, because its not how things around us behave.
For instance, take a book on a shelf. No two people in the room will even agree how much energy it has (it depends what you measure it compared to - the floor, the ceiling, the centre of the earth). Or a person on a train - their kinetic energy is high relative to the ground but zero relative to the train.
And there are many different guises to energy - heat, light, electrical etc.
But the law of conservation says that the total amount of energy always stays the same.

Conservation of energy states that the total amount of energy (in mechanics often expressed as the sum of kinetic energy and potential energy) in an isolated system remains constant. In other words, energy can be converted from one form to another, but it cannot be created nor destroyed. In modern physics, all forms of energy exhibit mass and all mass is a form of energy.
In thermodynamics, the first law of thermodynamics is a statement of the conservation of energy for thermodynamic systems.
The energy conservation law is a mathematical consequence of the shift symmetry of time; energy conservation is implied by the empirical fact that physical laws remain the same over time

The Law is
Energy can neither be created nor destroyed. It can be converted from one form to another. The total amount of Energy in the Universe remains constant at all the times.
K.E=1/2mv^2
P.E=K.E at Rest

according to the law of conservation of energy, energy can neither be created nor bedestroyed.it only changes from one form to another.
