| The history of the wind energy | |

La Cour, is considered to the meteorologist Pour as Urvater, of the modern
generation of current by wind. The first wind-powered device was built in 1891, with
that we could produce electricity. It used the then available windmills around the
wind to catch and it into electricity to convert. In the course 2. World war built the Danish company F.L. Smidth several two and three-blade wind-powered devices. Likewise at this time the two technical designers Smith and Putnam built a wind system north of New York. The tower height amounted to 33m and the whole construction had a diameter of more than 52m. A rotor blade flew with a case of loss over 230m far. Around the system one would have repaired much would have had to invest time and cash, therefore the operators decided that this power station was to be shut down. In the year 1956 J. Juul built a wind system, which is considered as a predecessor of the today's wind towers. It was a three-blade system with electromechanical wind adjusting. Juul's construction was long the largest and most reliable of the world. The oil crisis 1973 aroused the interest in the renewable energy in several countries. In Denmark many, large systems were built. In addition, the same occurred in the USA, Sweden, Germany and Great Britain. The maintenance was however very expensive and the electricity tariffs accordingly high. Only 1980 wind power stations were designed, with which one could produce more than 50kW. This had the consequence that the electricity tariffs sank around approximately 50%. The Americans (special the Californier) turned out in a proper "wind intoxication". Wind systems shot such as mushrooms from the soil at this time in California. When however around 1985 the interest sank again, many wind power stations disappeared over night. At present there is the largest "wind market" in Germany and also in other countries begins the interest in this energy again to grow. |
