How are wind energy and water energy converted into electrical energy?

First of all, you need to understand the principle of a generator. You must have been in contact with (it is recommended to go to a hardware store to check it) a small generator when we spin the rotor. the generator, the generator stator will have a voltage output. But the question is how to run this generator? An external diesel engine? Also. In short, we can just keep it spinning. The principle of wind energy production is therefore very simple. He installs a “fan” on the generator rotor. When the wind blows on the "fan", the "fan" will rotate the generator rotor and stator. part of it will produce electrical energy. If it is to be applied to domestic or road lighting, we need to solve one problem, that is, the "fan" must always rotate in one direction. It's very simple, just add a "rudder" to the "fan". .
