Energy cannot be created, it can only change forms. In that case what is the source of tidal energy? What other energy is getting converted here?

Question

I know that it is caused by the Sun and Moon’s gravitational pull. But where is the energy coming from? Who is losing energy?

Is gravity an unlimited energy source?

Answer 1

Tidal energy is created by the gravitational forces between earth and the moon. The moons rotation has stopped and the earth’s rotation is slowing ever so slightly. Given enough time if nothing else changed the earth would stop rotating. So that is where some of the energy comes from.
