It means that energy cannot be created nor destroyed, but it can change from one form to another.(for example, mechanical energy to heat energy.)

The law of "conservation of energy" states that energy can neither be created nor destroyed by any chemical or physical means. These days, many scientists are talking about conservation. Conserving energy does mean saving energy.
That is because the law of conservation of energy states that you can not create new energy.
Conservation of momentum means the sum of Momentum is constant. Conservation of Momentum is the result of Conservation of Energy.
The law of conservation of energy itself is not strictly correct since nuclear reactions change a small amount of matter into energy, if this is what you mean.
Perhaps you mean "energy conservation", or equivalently, "conservation of energy". That refers to the fact that there is a quantity called energy, which can't be increased or decreased (in a closed system).

The Law of Conservation of Energy is not the work of a single scientist. The knowledge about this law developed gradually over several centuries, as more and more types of energy were recognized to be equivalent. For example, at some moment somebody recognized that kinetic energy could be converted into potential energy and vice versa, and at another moment, somebody else recognized that mechanical energy could be converted to heat energy at a fixed ratio.
The Conservation of Matter and the Conservation of Momentum are the consequence of the Conservation of Energy.
Conservation of energy means that the total energy of a system remains constant no matter what the internal changes are.
It means that energy is conserved; that is, the total amount of energy will neither increase nor decrease.
I am not sure how much of a proof this is; but light energy is involved both in conservation of energy, and in conservation of momentum. A photon has both energy and momentum.I am not sure how much of a proof this is; but light energy is involved both in conservation of energy, and in conservation of momentum.
