One of the most famous passages of Miguel de Cervantes\u2019 novel comes in Chapter VIII, when Don Quixote encounters the windmills of the plains of La Mancha and attacks them, believing them to be giants, despite the warnings of Sancho Panza. The knight and his steed, Rocinante, come out on the losing end and are dragged by the blades of the windmill.<\/p>\n

This is quite the opposite of what has happened to the Spanish wind power sector, which is one of the strongest in the world. Today, the traditional windmills of La Mancha, now major tourist attractions, coexist with more than 20,000 state-of-the-art wind turbines spread over more than 1,100 wind farms across the country, which now produce 19% of the electricity consumed per year in Spain. Generating 23,484 megawatts of power every year, Spain is ranked fifth in the world and second in Europe for installed wind power, although it is not Castilla-La Mancha, but Castilla y Le\u00f3n (followed by Galicia) that is the region with the highest installed power. Wind is now the primary source of renewable energy in Spain, and the second largest in the energy mix.<\/p>\n

Wind power is produced when horizontal air currents (vertical ones do not have sufficient dynamic energy) move the blades of a wind turbine. This kinetic energy (caused by movement) is transmitted to a turbine, which transforms it into electricity. This passes through a power line to a distribution substation that is part of the grid, and from there to the end user. To be able to install a wind farm, the average wind speed in the area needs to reach at least 21 km\/h.<\/p>\n
