Normally directly behind the blades of a wind turbine is the alternator unit which produces alternating current (AC) electricity. This is a concept. They also found that the turbines worked over a wider range of wind conditions than standard turbines—they would turn under lower wind conditions and were not as susceptible to wear and tear under high wind conditions. These features make the wind turbine pleasant to live with. Thermoplastics can be melted and re-used, making it possible to recycle the blades into new wind turbine blades, even on-site. It was not recognized at that time that collisions with the rotating blades on the wind turbines would kill thousands of birds at the wind farms. This force vector acts on the rotor and is the driving force of the wind turbine. Engineers strive to design blades that extract as much energy from the wind as possible in a variety.
