It's called hydro-electricity, with hundreds of power stations around the world. The falling water is used to power a turbine generator which produces electricity.
You'd need to live in an area where hydro electricity is available. Most electricity suppliers have green power available at an extra cost, which would include hydro. It's exactly the same electricity as the normal stuff, but you're paying the extra for the them to supply some from eco friendly sources.

All hydroelectric power stations use this energy to generate power. However, it is inefficient to generate power directly from an open water fall.

The normal procedure is to build a dam at the head of the water fall, allow the water to flow down to the lower level through penstock pipes, and let the water jet turn a Pelton wheel turbine. Automatic controllers (governors) regulate the output of water so that the turbine rotates at constant speed. This is to maintain a constant out put frequency at the alternator connected to the turbine. The frequency has to be maintained at 50 +/- 1 Hz.

to answer this question first know about what power mean. power is the amount of work done in a rate of time. then to do work there must be energy change, so here comes your qus'n look what kinds of change of energies are there.
1- potential energy of water fall to kinetic energy of turbine.
2-kinetic energy of turbine to rotating magnetic field
3-rotating magnetic field by inducing current to a coil , electricity can be gained.

Have a mechanism to spin the turbine when water falls with a lot of pressure. Leave the rest to the turbine.

Water fall is having potential energy converted to kinetic energy, and the kinetic energy can be converted into mechanical energy by running the turnbine and the rotary motion can be transferrred and electrical energy can be converted.
But the only disadvantage is the flow of water is not constant and gives lot of fluctuation.

there are turbines located near the waterfall...and due to the force of the water ...those turbines start rotating to generate electricity...basically..mecha* power is converted to electrical power
*mechanical

You need a water wheel, an generator/alternator and a large capacitor to store the electricity and discharge when needed.

Build a water wheel or turbine generator. Of course it will ruin the beauty of the waterfall and the local ecology, but you'll have "free" power. Or will you?

when we make water to fall on the turbo, it starts rotating, which gives the electricity. here water energy is converted into electrical energy.

Probably better move close to one and set up a turbine for the water to turn and whatever else it takes to make it work. I don't know all the details.
