How can we show mathematically that a wave transfer energy?

Look up "Feynman's sticky beads". Feynman used this (embarassingly simple) argument to show that gravitational waves carry energy. Modifying it for a mechanical wave is simple.

I just want a simple explanation.

I thought you wanted the math. If you want a simple explanation, never ask for the math behind something.
 
On the other hand, explanations without math are either more complicated than with math or wrong.
