If you mean hydraulic energy, you don't really "convert water to energy". If the water is in a higher position, it has more energy (potential energy); when it falls down, this potential energy is converted to some other type of energy.
We can convert electrical energy into mechanical energy in mixer and grinder. We can convert electrical energy into sound energy in various sound systems. We can convert electrical energy into heat energy in electric water or room heater.
Photosynthesis uses the energy of sunlight to convert water and carbon dioxide to sugar.
A dam does not transform mechanical energy from the motion of water into electrical energy. A turbine can convert the kinetic energy of moving water, coming from a dam, a river, or anywhere, into mechanical energy, which a generator then takes to convert that into electrical energy.
Water pump is the best example
You could for instance convert the nuclear energy to mechanical or electrical energy and use it to pump water up into a high reservoir, where it will have potential energy.
kinetic & heat energy
convert energy from falling water to electrical energy?
Let falling/running water turn a water wheel, hydroenergy to mechanical energy.
its photosynthesis
Of course it does numb nuts
Falling water , gravity energy, drives generators to produce electricity.
