The total amount of energy in the universe is constant. To do something you use energy, but you don't really "use" it (as in it disappears), you just change it into something else (like motion or heat). Unless you don't mean how it's done, but actually "Why". Because that's like asking what the meaning of life is

Conservation of energy

63 Cu nucleus has 29 protons and also has (63 – 29) 34 neutrons.. The mass of a proton is 1.00728 u and a neutron is 1.00867 u.. The combined mass is: 29 protons x (1.00728 u/proton) + 34 neutrons x (1.00867 u/neutron) = 63.50590 u (No surprise there. Lost energy is inevitable.) Somewhere in the middle of the 20th century, however, the situation reversed. The potential energy of world class pole vaulters now routinely exceeds the kinetic energy of world class sprinters. It would appear that vaulters have discovered a way to "violate" the law of conservation of energy.

The law of conservation of energy states that energy can neither be created nor destroyed – only converted from one form of energy to another.This means that a system always has the same amount of energy, unless it’s added from the outside.

To do something you use energy, but you don't really "use" it (as in it disappears), you just change it into something else (like motion or heat). Unless you don't mean how it's done, but actually "Why". Because that's like asking what the meaning of life is Conservation of energy definition is - a principle in physics: the total energy of an isolated system remains constant irrespective of whatever internal changes may take place with energy disappearing in one form reappearing in another. The energy conservation law is a consequence of the shift symmetry of time; energy conservation is implied by the empirical fact that the laws of physics do not change with time itself.

Course Material Related to This Topic: Definition of the law of conservation of energy, with examples; definition of conservative forces and the potential energy of conservative forces.

But before getting into that you first need to understand what’s the importance of energy conservation or saving energy in general terms. Conservation laws as fundamental laws of nature. Conservation laws are fundamental to our understanding of the physical world, in that they describe which processes can or cannot occur in nature. For example, the conservation law of energy states that the total quantity of energy in an isolated system does not change, though it may change form.
