Wind power capacity has expanded to 369,553 MW by December 2014, and total wind energy production is growing rapidly and has reached around 4% of worldwide electricity usage.
What is wind energy? Wind energy is generated by harnessing the wind and is the worldâs fastest growing energy source. Itâs becoming more important for electricity companies to use wind energy as itâs a renewable and free resource.ach wind turbine has an internal computer system that monitors the direction and speed of the wind, and allows it to automatically set itself to operate at a safe level. If there is any damage to the turbine due to overcapacity (wind speed and strength), the turbines shut down automatically.
