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

Earth’s rotational speed slows down a little bit and the Moon slowly, very slowly moving further away from Earth. That’s the energy that is converted into the tides.
