During the last decade. renewable energies have taken on a great importance in the development of some countries. Developing this energy is increasingly the axis explored by the scientific community. The energy can be extracted from many sources. to cite fossil. solar and wind.Wind turbine technology has developed rapidly in recent years and Europe is at the hub of this high-tech industry. Wind turbines are becoming more powerful. with the latest turbine models having larger blade lengths which can utilize more wind and therefore 66 produce more electricity. bringing down the cost of renewable energy generation. Wind turbines produce electricity by using the natural power of the wind to drive a generator. The wind is a clean and sustainable fuel source. it does not create emissions and it will never run out as it is constantly replenished by energy from the sun. In many ways. wind turbines are the natural evolution of traditional windmills. but now typically have three blades. which rotate around a horizontal hub at the top of a steel tower. Most wind turbines start generating electricity at wind speeds of around 3-4 meters per second (m s). (8 miles per hour). generate maximum ‘rated’ power at around 15 m s (30mph). and shut down to prevent storm damage at 25 m s or above (50mph).
