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.
Water energy can be converted into electrical energy through hydropower plants. These plants use the force of flowing water, such as rivers or dams, to turn turbines connected to generators that produce electricity. The spinning turbines convert the kinetic energy of the moving water 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
A hydroelectric turbine is used to convert the energy of moving water into electrical energy. This turbine is connected to a generator that produces electricity as the water flows through the turbine.
Falling water , gravity energy, drives generators to produce electricity.
Photosynthesis is the process by which plants convert the energy from the sun's light into chemical energy.
This hydroelectric dam will convert the water's energy into electricity for the entire town.
