Wind Energy

Wind energy is a renewable energy source that uses the power of the wind to generate energy. This process happens through wind turbines, which operate as follows: blowing air passes through the turbine blades, causing them to spin, which triggers the main shaft of the turbine. Have you ever looked at a wind turbine and wondered why the blades rotate so slowly and yet it is possible to produce energy? If you have asked yourself this question, here is the answer: in fact the turbine spins slowly (about 18rpm, which is not fast enough to generate power) and that is why the rotor shaft of the turbine is connected to a series of gears (gearbox) that will increase the rotation up to 1800 rpm. At this speed, the generator that is connected to the gearbox can generate a lot of electricity.
