Is there proof gravity can not be a energy source?

[Omnibus]

4 statements above, 2 false assertions due to ignorance or stupidity. 

There is energy in the gravity field. Gravity is not force.
When two bodies attract one each other, and accelerate, energy is taken from their gravitational field, whose energy density decreases while the field redistributes in space, changing of topology due to the bodies movement.
Gravity field energy density is: D = g²/(8*pi*G). 
It is the same as the energy density of an electric field (1/2*epsilon0 * E²) or magnetic field (1/(2*mu0) * B²). It is a general law when fields are the source of 1/r² forces.

Now the above is nothing short of sheer crap. There's a reason why I'm so adamant when telling off this confused element going by the handle @exnihiloest. His aggressive confusion and incompetence can be really damaging for people already confused enough to be pounced by another blind leading the blind.

The formuli above are akin to gravitational potential energy. The fact that a body in a gravitational field placed at rest at a given position in this field has gravitational potential energy does not at all mean that gravity is a source of energy. It is absolutely not true that a body at rest in a field of gravity does anything to the gravity, depleting it in some way. Nor does a body deplete gravity when moving under the action of that force. It has to be understood once and for all, there is potential energy connected with gravity (as with other fields detived from a potential) but gravity is not a source of energy, it is not a pool of energy which can be depletednto do work. Gravity is force which is different from energy and that force can do work provided it induces displacement of a body with mass. Therefore, not only there's no proof that gravity is a source of energy but such proof cannot even be sought for because energy and force are incompatible when trying to equate them.

So the question is answered.

a well-known proof is Hydroelectricity

look at the strong rain falling on the ground and you see the power

and look at the Gwatt of electricity produced ( approximately 20% of the world's electricity )

I thought it was over but I guess not.

The actual energy for this comes from the sun that evaporates the water and runs the weather cycle that brings in the rain and deposits the water at higher elevations so a waterfall can exist. So the energy is only indirectly produced from gravity.

It is not a proof. The solar energy is the primary source of rain: water evaporation, then condensation, fall on earth and the cycle continues. The energy of gravity is not concerned, it is balanced, the same mass of water that falls, had been raised before by the sun energy.

Blah blah blah, an act of faith asserted arbitrarily, not scientific because refutable elements are not provided. I don't discuss Coran sourats.
