• Generating electricity from wind power is one of the fastest growing methods in the world. The kinetic energy of the moving air is converted into electricity by wind turbines that are installed in places where the weather conditions are most favorable. Wind turbines can be used individually, but are often grouped together to form wind parks also called wind farm. Electricity generated from wind parks can be used to meet local needs or to supply an electricity distribution network for homes and businesses further away. Energy obtained from the wind can also be converted into hydrogen and used as transport fuel or stored for subsequent electricity generation. The use of this form of energy, reduces the impact of electricity generation on the environment as it does not require fuel and does not produce any pollutants or greenhouse gases. Wind energy is growing significantly and since 1994 the world market has grown by around 30% per year. The installed capacity worldwide rose from 17,400 up to 650,560 MW between 2000 and the end of 2019. In the European market, which concentrates most of the world's wind farm, Germany remains the leader with almost half of the total capacity. Spain recorded the strongest growth in the last three years with an annual growth rate of 28%. Europe also concentrates industrial and technological activities: Eight European manufacturers are among the top ten in the world, with 70% of devices sold in 2018.
